Find the slope of the line containing the points (-3, -6) and (4, 7).
Answer:
[tex]\frac{13}{7}[/tex]
Step-by-step explanation:
→ State the slope formula
( y₂ - y₁ ) ÷ ( x₂ - x₁ )
→ Substitute in the values
( 7 - -6 ) ÷ ( 4 - -3 )
→ Simplify
[tex]\frac{13}{7}[/tex]
Answer:
slope = [tex]\frac{13}{7}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, - 6) and (x₂, y₂ ) = (4, 7)
m = [tex]\frac{7-(-6)}{4-(-3)}[/tex] = [tex]\frac{7+6}{4+3}[/tex] = [tex]\frac{13}{7}[/tex]
Mr. A runs 500 meters in 1 minute, Mr. R runs 450 meters in 50 seconds, Mr. M runs 600 meters in 70 seconds and Mr. K runs 400 meters in 45 seconds. Based on these times, which runner would win a 100 meter race?
Step-by-step explanation:
1minute=60seconds
500 meters=60
100 meters=x
cross multiply
500×x=100×60
500x=6000
x=12
Mr. A will use 12seconds
450meters=70
100=a
cross multiply
450×a=100×70
450a=7000
divide both sides by 450
400=45
100=n
cross multiply
400×n=100×45
400n=4500
divide both sides by 400
divide and get your answer

Find an equation in general form for the straight line that passes through the point (-1.4) and is
perpendicular to the line 2x + 3y = 6
9514 1404 393
Answer:
3x -2y +11 = 0
Step-by-step explanation:
The equation of the line perpendicular to ax+by=c through point (h, k) can be written as ...
b(x -h) -a(y -k) = 0
Simplifying this will put it in general form.

Write 2.4 × 1012 in standard notation.
Answer:
2,400,000,000,000
Step-by-step explanation:
2.4 x 10^12 means that the decimal point is moved 12 places to the right (hence the power of 12)
So by moving the decimal point 12 times you get this: 2,400,000,000,000
The reason why there are only 11 zeroes is because the 4 was a decimal place to the right of 2, thus losing a zero.
the perimeter of a rectangle is 68 feet the length is 5 inches shorter than twice the width what are the dimensions of the rectangle
Answer:
Step-by-step explanation:
The perimeter formula is P = 2L + 2W. If the perimeter is given as 68 feet, then our P will be filled in with 68. If the length is "5 inches shorter than twice the width" is an expression that looks like this, keeping in mind that "shorter" means subtraction, "twice" means doubled, and the word "is" means equals:
L = "length is"
2W is "twice the width"
5 inches shorter is " - 5". Putting it all together:
L = 2W - 5. Now we can fill in the perimeter formula:
68 = 2W + 2(2W - 5) and
68 = 2W + 4W - 10 and
68 = 6W - 10 and
78 = 6W so
W = 13. The width is 13 inches and the length is
L = 2(13) - 5 so the length is
L = 21 inches.

The volume of this cube is 64 cubic feet. What is the value of a?
Answer:
a = 4 feet
Step-by-step explanation:
Since it's a cube, we know that each value will be equal. Because of this, you can cube root the cube's volume to find a.
[tex]\sqrt[3]{64}=4[/tex]
Therefore, a = 4 feet.
Answer:
4
Step-by-step explanation:
To find the area of a cube, we have to multiply the width, height, and length, which, since they are all the same value, would be a side multiplied by itself 3 times(cubed). So, the area of this cube in terms of a(side) is a*a*a or a^3. The area is given to be 64, so we can write:
a^3 = 64
With the equation, we can realize 4*4*4 is 64, meaning a is 4.

Calculate using order of operations. 7.8+6.2×(4-1.5)×4 full formula
Answer:
[tex]69.8[/tex]
Step-by-step explanation:
order of operations can be abbreviated as GEMDAS 1. Groups 2. Exponents 3. Multiplication and Division 4. Addition and Subtraction
So start by writing out the equation
[tex]7.8+6.2*(4-1.5)*4[/tex]
Slove anything grouped with parenthesis or other grouping symbols
[tex]7.8+6.2*(2.5)*4[/tex]
There are no exponents so skip to Multiplying and Dividing
[tex]7.8+15.5*4[/tex]
[tex]7.8+62[/tex]
Then Addition and Subtraction
[tex]69.8[/tex]
(also I already know that most people write it as PEMDAS as in parenthesis instead of groupings but I personally prefer to abbreviate it as GEMDAS and that is an opinion for a reason)

Shannon, who is paid time-and-a-half for hours worked in excess of 40 hours, had gross weekly wages of $551 for 52 hours worked. What is her regular hourly rate?
Answer:
frnddcchdddssjegtgeeusiss ehejsbdvbsjwjgebee e e e e r ytjrbehww
Answer:
$9.5
Step-by-step explanation:
40x+12*1.5x=551
40x+18x=551
58x=551
58x/58=551/58
x=9.5
I put 40x to represent her normal rate when she isnt working overtime which is over 40 hours. And then I put 12*1.5x which is broken down into two parts, 12 represent the amount of overtime hours worked 12 hours overtime (52-40=12) and 1.5x represents the time-and-a-half (which if you didnt know is where you get paid 1.5 times your hourly wage each hour worked overtime). And when you solve this equation you get 9.5 hours an hour as her regular hourly rateSandra is 5 years old. When she asked her father about his age, he gave her this answer.

michelle is 3 times as old as her sister tina. Tina is 4 years younger than michelle. How old is tina now?
Answer:
Tina's age = 2 years
Step-by-step explanation:
Tina's age = x
Michelle's age = 3 * x = 3x
Tina is 4 years younger than Michelle.
x = 3x - 4
Add 4 to both side
x +4 = 3x
Subtract x from both sides
4 = 3x - x
4 = 2x
Divide both sides by 2
4/2 = x
2 = x
Tina's age = 2 years

How much money will be in a bank account after 3 years if $9 is deposited at an interest rate of 5% compounded annually? Round to the nearest dollar.
Answer:
$10.42
Step-by-step explanation:
Compound interest formula: A=p(1+r/n)^nt
9=p, r=0.05, n=1, and t=3
A=9(1+0.05)^3
A=9(1.05)^3
Plug this into calculator and you get $10.42
Answer:
A = $10.42
Step-by-step explanation:
The appropriate formula is the "compound amount" formula given by
A = P(1 + r)^t,
where P is the initial amount, r is the annual interest rate as a decimal fraction, and t is the number of years elapsed.
Here:
A = $9(1 + 0.05)^3, or
A = $9(1.05)^3, or
A = $10.42

Consider that 45% of Americans own a dog, 25% of Americans own a cat, and 40% of Americans own neither. Draw a Venn Diagram for this situation. Be sure to label every region of the Venn Diagram with a word AND the percentage of Americans that fall in each category.
Answer:
See below
Step-by-step explanation:
40% own neither, it means 100% - 40% = 60% own either a dog or a cat.
Since 45% own a dog, 60% - 45% = 15% own a cat but not a dog.
Since 25% own a cat and 15% own only a cat, 25% - 15% = 10% own a dog and a cat.
Now, 10% out of 45% own both pets, 45% - 10% = 35% own only a dog.

given that tan x =3/7find cos (90-x) giving you answer in 4 significant figures
Answer:
[tex]\cos \left(90 ^\circ - x\right) \approx 0.1688[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \tan x = \frac{3}{7}[/tex]
And we want to find the value of:
[tex]\displaystyle \cos \left(90^\circ - x\right)[/tex]
Recall that by definition, tan(θ) = sin(θ) / cos(θ). Hence:
[tex]\displaystyle \frac{\sin x }{\cos x} = \frac{3}{7}[/tex]
And by definition, sin(θ) = cos(90° - θ). Hence:
[tex]\displaystyle \frac{\cos \left(90^\circ - x\right)}{\cos x} = \frac{3}{7}[/tex]
Multiply:
[tex]\displaystyle \cos \left(90 ^\circ - x\right) = \frac{3}{7} \cos x[/tex]
Find cosine. Recall that tangent is the ratio of the opposite side to the adjacent side. Therefore, the opposite side is 3 and the adjacent side is 7.
Thus, by the Pythagorean Theorem, the hypotenuse will be:
[tex]\displaystyle h = \sqrt{3^2 + 7^2} = \sqrt{58}[/tex]
Cosine is the ratio of the adjacent side to the hypotenuse. Therefore:
[tex]\displaystyle \cos x = \frac{7}{\sqrt{58}}[/tex]
Thus:
[tex]\displaystyle \cos \left(90 ^\circ - x\right) = \frac{3}{7} \left(\frac{3}{\sqrt{58}}\right)[/tex]
Use a calculator. Hence:
[tex]\cos \left(90 ^\circ - x\right) \approx 0.1688[/tex]
