Answer: 26
Step-by-step explanation:
From -10 to 0 will be 10
1 to 16 are 16
Answer:
Step-by-step explanation:
There are several things you need to know in order to write the absolute value equation for a situation. First is how to formulate what you need. The absolute value equation follows the formatting:
| x - midpoint | = the distance between the midpoint and one of the endpoints.
That means we also need to be able to find the midpoint of -10 and 16. Finding the midpoint is finding the middle, which is the same as finding an average of the 2 numbers.
[tex]M=\frac{-10+16}{2}=3[/tex]
So the midpoint is 3. The distance between 3 and either one of the endpoints is going to be the same, by definition of the midpoint of the 2 numbers. The distance between 3 and 16 is 13 units. The distance between 3 and -10 is also 13 units. So, to put this into an absolute value equation,
| x - 3 | = 13

Answer: yes 3/5 equal to 60/100
Step-by-step explanation:
The answer is it is because if you do
5 times 20 its 100
and 3 times 20 is 60
so what you do to the bottom you do to the top
so the answer is yes 3/5 equal to 60/100
Hope this helps :)
Answer:
Yes
Step-by-step explanation:
[tex]\frac{3}{5} and \frac{60}{100}[/tex] are equivalent fractions. Equivalent fractions are fractions that have the same value of decimal. so when you simplify 60/100 you will definitely get 3/5. And both of their's decimal is equal which is 0.6.

If Morgan paints for x hours and Sophia paints for y hours, they will finish half of the painting, while if Morgan paints for y hours and Sophia paints for x hours they will paint the whole room. Find the ordered pair (x,y), expressing both x and y as simplified fractions.
Answer:
x,y = ( 3 17/21 , 10/21)
Step-by-step explanation:
Painting the room = 1 whole job
Morgan rate = 1/10
Sophia rate = 1/4
Rate x time = 1 job
1/10 x + 1/4 y = 1/2 and
1/10 y + 1/4 x = 1 solve for x,y
Multiply the top equation by - 2.5
(-2.5)/10 x - (2.5/4) y = -1.25
-1/4 x - 5/8 y = -1 .25
and add to the second equation to get
1/10 y - 5/8 y = -.25 solve for y
4/40 y - 25/40 y = -.25
-21/40 y = - .25
y = 10/21 hr Substitute this into one of the original equations to find 'x'
1/10 (10/21) + 1/4 x = 1
1/21 + 1/4 x = 1
1/4 x = 20/21
x = 80/21 x,y = ( 3 17/21 , 10/21)

Here is some information about a play starts at 7:30pm first act last 46 minutes interval lasts 20 minutes second act last 53 minutes at what time does the second act end
Answer:
9:29 PM
Step-by-step explanation:
Let us add the number of minutes the first act, interval and second act lasted:
46 + 20 + 53 = 119 minutes
Converting this to hours and minutes:
60 minutes = 1 hour
119 minutes = 1 hour 59 minutes
Therefore, the time that the second act ends is:
H M
7 : 30 PM
+ 1 : 59
9 : 29
The second act will end by 9:29 PM
A manufacturer designs a circular ornament with lines of glitter as shown. Identify m∠PSR.
m=60
m=30
m=90
m=120
Answer:
120
Step-by-step explanation:
The measure of the arc QR⏜ intercepted by the inscribed ∠QPR is given.
According to the Inscribed Angle Theorem, the measure of the inscribed angle is equal to one-half the measure of the arc.
m∠QPR=12mQR⏜
Substitute 60° for mQR⏜.
m∠QPR=12(60°)
Simplify.
m∠QPR=30°
The figure shows the same circle as in the beginning of the task. Triangle P R S is highlighted in red. Angle S P R measures 30 degrees.
It is given that m∠SRP=30°. Use the Triangle Sum Theorem to find the measure of the unknown ∠PSR.
m∠SRP+m∠SPR+m∠PSR=180°
Substitute the known values.
30°+30°+m∠PSR=180°
Simplify.
60°+m∠PSR=180°
Subtract 60° from both sides.
m∠PSR=120°
Therefore, m∠PSR=120°.
PLZ HELP! Joel rolls two fair number cubes at the same time. What is the probability that the sum of the numbers will be odd or less than 4? Show your work.
Answer:
Joel rolls two fair number cubes at the same time.
Each cube has six sides 1, 2, 3, 4, 5, 6
=> There are 6 x 6 = 36 possible pairs (or 36 possible sums)
The collection of pairs that have sum less than 4 includes (1, 2), (2, 1) and (1, 1) => 3 cases (*)
The sum that is odd when two cubes show one odd number and one even number. Therefore each side of first cube has 3 options from second cube to form an odd sum. => The total number of cases: 6 x 3 = 18 cases
In these 18 cases, there are two cases (1, 2) and (2, 1) which have been counted already at (*) => Total case that the sum of the numbers will be odd or less than 4: T = 3 + 18 - 2 = 19 cases
=> Probability that the sum of the numbers will be odd or less than 4:
P = 19/36 = 0.53

Answer:
Just put the values of x and y
x = 1
y = -2
2x – y = p
2(1) - (- 2) = p
p = 4
Answer:
The value of p is 4.
Step-by-step explanation:
In order to find p, you have to substitute the value of x and y into the linear equation :
[tex]2x - y = p[/tex]

Given the following exponential function identify weather the change represents growth or decay and determine the percentage rate of increase or decrease y=550(0.97)x
Answer:
The exponential function is that of decay
The percentage decrease is by 3%
Step-by-step explanation:
The exponential equation we are considering is;
y = 550(0.97)^x
Now to know if it’s decay or growth, we shall be considering what we have in the bracket
Mathematically, we can express 0.97 as follows
0.97 = 1-0.03
So what does this means? There is a decrease in subsequent values from one value of y to another.
This means that the equation is for decay as what the term raised to an exponent is less than 1.
Now we want to determine the percentage rate of increase or decrease
What we need to do is to represent the 0.03 difference in fraction
That would be 3/100
So this means that the percentage decrease is by 3%

In a local city, the temperature at noon is Negative 3 degrees Celsius. The temperature is expected to decrease by 2.5 degrees Celsius each hour until the temperature reaches Negative 18 degrees Celsius. How many hours will it take for the temperature to reach Negative 18 degrees Celsius? 6 hours 7 hours 7.2 hours 8.4 hours
Answer:
6
Step-by-step explanation:
It takes 6 hours to reach -18°C. Therefore, option A is the correct answer.
Given that, the temperature at noon=-3°C, every hour temperature decreased by -2.5°C.
How do multiply whole numbers and decimals?Multiplying Decimals has the same procedure as that of multiplication of the whole numbers, except for the placement of the decimal point in the product.
Now, every hour temperature decreases by -2.5°C, we need to find how many hours it takes to -18°C.
So, -2.5×6=-15°C
Then, final temperature=initial temperature+increased temperature.
=-3°C+(-15°C)=-18°C
Therefore, option A is the correct answer.

Adult Golden Retrievers have a mean weight of 64 pounds with a standard deviation of 8 pounds. If you take a random sample of 35 gold retrievers, what is the probability the sample mean will be less than 65.5 pounds?
0.8643
0.1357
0.8665
0.1335
Answer:
Step-by-step explanation:
Let x be the random variable representing the mean weight of Adult Golden Retrievers. Assuming the weights are normally distributed(number of samples is greater than 30), we would apply the formula,
z = (x - µ)/(σ/√n)
Where
x = sample mean
µ = population mean
σ = standard deviation
n = number of samples
From the information given,
µ = 64
σ = 8
n = 35
the probability that the sample mean will be less than 65.5 pounds is expressed as
P(x < 65.5)
For x = 65.5,
z = (65.5 - 64)/(8/√35) = 1.11
Looking at the normal distribution table, the probability corresponding to the z score is 0.8665
Therefore, the probability that the sample mean will be less than 65.5 pounds is 0.8665

at which root does the graph of f(x)=(x+4)^6(x+7)^5 cross the x-axis ?
Answer:
-7
Step-by-step explanation:
The equation is simplified so there are two possible answers here, -4 and -7
There is a root where y = 0 and x = a number
At -4 and -7 y = 0
However at -4 the function bounces since the (x+4) is raised to the 6th power.
When you have an even power, the function bounces at the x-axis, and when you have an odd power the function goes through the x-axis.
Since you can only choose one answer, the logical answer would be -7.
At x = -7, y = 0 and the function crosses the x-axis.
At x = -4, y = 0 but the function bounces on the x-axis.
The logical answer here is -7.
The graph crosses the x-axis at x = -7
RootsThe roots of a function are the zeros of the function
The function of the graph is given as:
[tex]f(x) =(x+4)^6(x+7)^5[/tex]
EquationIn the above equation, the roots of the functions and their corresponding multiplicities are:
Root: -4, Multiplicity: 6Root: -7, Multiplicity: 5x-axisThe graph will cross the x-axis, when the multiplicity is odd
The root, -7 has an odd multiplicity.
Hence, the graph crosses the x-axis at x = -7

The average of two numbers is 7, and three times the difference
between them is 18. Find the numbers. use the simultaneous equation plz guys
Answer:
10 & 4
Step-by-step explanation:
Let the numbers are a and b.
Their average = 7
= > ( a + b ) / 2 = 7
= > a + b = 2 * 7 = 14 ...( 1 )
Also,
= > 3 times of difference between a and b = 18
= > 3( a - b ) = 18
= > a - b = 6 ... ( 2 )
adding ( 1 ) & ( 2 ) :
= > ( a + b ) + ( a - b ) = 14 + 6
= > 2a = 20
= > a = 10
Thus,
= > a + b = 14 → 10 + b = 14
= > b = 14 - 10 = 4
