Answer:
19%
Step-by-step explanation:
40/50 = x/100
solve for x
x is equal to 20%
but out of the answer choices it's 19%.
Answer: 19%
Step-by-step explanation:
50, percentage decreased by 60% (percent) of its value = 20
50, percentage decreased by 80% (percent) of its value = 10
50, percentage decreased by 19% (percent) of its value = 40.5
50, percentage decreased by 40% (percent) of its value = 30
Hence, the answer is 19%

Move the radius x to make a right triangle. The 6 unit segment bisects the chord. So, the legs of the right triangle are 6 and 9
The use the Pythagorean theorem to find x, which is the hypotenuse of the right triangle. Now,
[tex]6^{2} + 9^{2} = x^{2}[/tex]
[tex]x^{2} = 36 + 81 = 117\\x = \sqrt{117} = 3\sqrt{13}[/tex]= 10.8
None of the answer choices are to the nearest tenth. So, I am confused about that.
In the second problem, the answer should be 11.2

Answer:
1/2 and 3
Step-by-step explanation:
The quadratic formula is as given:
( -b±√(b^2-4ac) )/2a
To use it, plug in the a,b and c values.
ax^2+bx+c
In this case a is equal to 2, b is equal to -7, and c is equal to 3
plugging it into our formula gives us:
(-(-7)±√(-7^2-4*2*3) )/2*2
Which is equal to:
7±√(49-24) / 4
= 7±√25 / 4
=7±5 / 4
=2/4, 12/4= 1/2, 3

Each football game begins with a kickoff. The formula h = - 16t ^ 2 + 64t , where h is the height in feet of the football at t seconds, can be used to model a kickoff that is in the air for 4 seconds. At what times will the football be 48 feet above the ground?
The ball will be 48 feet above the ground at the times of
1 second and 3 seconds.
How to obtain the times?The quadratic function for this problem is defined as follows:
h = -16t² + 64t.
The ball is 48 feet above the ground when h(t) = 48, hence:
-16t² + 64t = 48.
16t² - 64t + 48 = 0.
The equation can be simplified by 16 as follows:
t² - 4t + 3 = 0.
Factoring the expression, we have that:
(t - 3)(t - 1) = 0.
Applying the Factor Theorem, the times are given as follows:
t - 3 = 0 -> t = 3 seconds.t - 1 = 0 -> t = 1 second.More can be learned about quadratic functions at https://brainly.com/question/1214333

According to the line plot, what is the total amount of time spent studying by the students who studied for an hour each?
Answer:
2.5 hours
Step-by-step explanation:
The total amount of time studying by students who spent 1/2 an hour studying is the product of the number of students who spent 1/2 an hour studying by 1/2 an hour.
Hence, counting the number of dots on the point marked 1/2 gives the count of students who spent 1/2 an hour studying and multiply this number by 1/2.
Total amount of hours spent = 1/2 * 5 = 2.5 hours
Three boys spent the afternoon playing a video game and then compared their best scores. Al says, "My best today is 1800 points more than yours, Bob." Carlo says, "I was having a good day. My 7200 points is 2/3 as much as your two scores combined, Al and Bob." How many points did each boy get in his best game that afternoon?
Answer:
Bob = 4500
Al = 6300
carlo = 7200
Step-by-step explanation:
the following equations can be derived from the question
A = B + 1800 equation 1 or A - B = 1800
C = 7200 = 2/3 (A + B) equation 2
where A = Al's score
B = Bob's score
C = Carlo's score
Make A + B the subject of the formula in equation 2
A + B = 10,800 equation 3
subtract equation 1 from 3
2B = 9000
B = 4500
Substitute for B in equation 1
A = 4500 + 1800 = 6300
The general term of a sequence is given by an = 7+3 (n-1) for n > 1.
Which recursive formula defines this sequence?
9514 1404 393
Answer:
E
Step-by-step explanation:
The general term matches the form ...
an = a1 +d(n -1)
for a1 = 7 and d = 3.
This is the form for the general term of an arithmetic sequence with first term 7 and each successive term 3 more than the previous one.
That description matches the recursive formula ...
a(1) = 7; a(n) = a(n-1) +3 . . . . . choice E

answer: [x]
Answer:
-36
Step-by-step explanation:
replace x with -5 and solve for the parenthesis and then take that number which would be -16 and multiply it by 9 which then would give you -144. So then you would take -144 and divide it by 4 and your answer would be -36.

what would be the leading coefficient of f(x)=6-x+7x^2
Answer:
7
Step-by-step explanation:
The leading coefficient of the given expression is 7.
What is coefficient?A coefficient is a factor that is multiplied by a variable or a term in an expression. It can be a number or a symbol representing a constant value. For example, in 7x - 3y + 5, the coefficients are 7, -3, and 5.
Given that a quadratic function f(x) = 6-x+7x², we need to find the leading coefficient,
So, rearranging the terms in the function in standard form,
f(x) = 7x²+x-6
The leading coefficient is the coefficient of the term with the highest power or degree in a polynomial,
Here, the highest power coefficient is 7.
Hence, the Leading coefficient of the given expression is 7.

Circle A has center of (−2, 4) and a radius of 4, and circle B has a center of (3, 9) and a radius of 8. What steps will help show that circle A is similar to circle B?
Translate circle A using the rule (x − 5, y − 5).
Dilate circle A by a scale factor of 2.
Reflect circle A over the axis.
Rotate circle A 90° clockwise about the center.
To go from circle A to B, we apply a translation of <-5, -5> and a dilation of scale factor k = 2.
What steps will help show that circle A is similar to circle B?The equation for circle A is:
(x + 2)^2 + (y - 4)^2 = 4^2 = 16
The equation for circle B is:
(x - 3)^2 + (y - 9)^2 = 8^2 = 64
So, if we start with circle B, we need to apply a translation of <-5, -5> to go to the center of B, then if we apply a dilation of scale factor K, the radius of the circle becomes 4*k.
Particularly of k = 2, we get:
4*2 = 8
So the scale factor k = 2 transforms the radius from 4 to 8.
Finally, if we apply these two transformations to circle A, we get circle B, which means that the circles are similar.

Find the values of x and y that make these triangles congruent by the HL Theorem.
Answer:
x = 3 ; y=2
Step-by-step explanation:
to simplify the work we can build a system of two equations
2x+3 = 3y+3
x = y+1
we can now substitute the value of x in the first equation
2(y+1)+3 = 3y+3
2y + 2 + 3 = 3y+3
2y + 5 = 3y+3
y = 2
now we can subisitute the value of y in the first equation
x = 2 + 1 = 3
Verify
2(3)+3 = 6+3 = 9
3(2) + 3 = 6 + 3 = 9

There are 8 red marbles, 5 blue marbles, 11 green marbles, 1 yellow marble in a jar. Suppose one marble is selected at random. P(red, green or yellow)
Given:
Number of red marbles = 8
Number of blue marbles = 5
Number of green marbles = 11
Number of yellow marbles = 1
One marble is selected at random.
To find:
The P(red, green or yellow).
Solution:
Number of red, green or yellow marbles = 8 + 11 + 1
= 20
Total number of marbles = 8 + 5 + 11 + 1
= 25
The probability of getting a red, green or yellow marble is:
[tex]P(\text{red, green or yellow})=\dfrac{\text{number of red, green or yellow marbles}}{\text{Total number of marbles}}[/tex]
[tex]P(\text{red, green or yellow})=\dfrac{20}{25}[/tex]
[tex]P(\text{red, green or yellow})=\dfrac{4}{5}[/tex]
[tex]P(\text{red, green or yellow})=0.8[/tex]
Therefore, the value of P(red, green or yellow) is 0.8.
