Answer:
A) 55 + x ≤ 100
B) 55 + x ≤ 70
Step-by-step explanation:
A Explanation - Inequalities use signs < , > , ≤ , and ≥. We also know you have 100 seconds to beat the level, so you have to solve it in 100 or less, which tells us the 55 + the time left (x) must be less than or equal to 100. Solved will be attached.
B Explaination -
Like A, you can use the same setup, but switching a value. You already have the 55, you need 70. Or less points to ≤, same as before, so you can keep it the same, except with the 70 instead of the 100. Solved attached.

For what value of k is the expression
4x2 – 8x +k a perfect square?
A.
B.
C.
D.
E.
64
32
16
8
4.
Answer:
[tex]k = 4[/tex]
Step-by-step explanation:
Given
[tex]4x^2 - 8x + k[/tex]
Required
Determine k if the expression is a perfect square
A quadratic is of the form;
[tex]ax^2 + bx + c[/tex]
Where (by comparison):
[tex]a = 4[/tex] [tex]b = 8[/tex] [tex]c = k[/tex]
If the above is a perfect square, then
[tex]k = \frac{b^2}{4a}[/tex]
Substitute values for a, b and c
[tex]k = \frac{8^2}{4*4}[/tex]
[tex]k = \frac{64}{16}[/tex]
[tex]k = 4[/tex]
Hence, k = 4

sally has 2/8 cookies in a jar she ate 1/4 how many dose she have left :explain
Answer:
1.5 cookies if 2/8 is like 2 cookies out of 8, 1/16 if its like 2/8 of a cookie
Step-by-step explanation: \
1.5: 2 x 3/4 (already ate 1/4) = 1.5
1/16= 1/4 (2/8 reduced) x 1/4
Solve for x. Leave your answer as a fraction.

Ten voltage measurements in a circuit have produced the following values: 49.3, 50.1, 48.9, 49.2, 49.7, 50.5, 49.9, 49.3, 49.8, 50.2 If the standard deviation for the above data set is 0.50 V, Which of the values can be rejected:
Answer:
48.9 and 50.5 are rejected.
Step-by-step explanation:
Since the standard deviation shows the spread of the values of the voltages, we need to find the mean of the values and use the standard deviation to find the minimum and maximum voltage allowed.
So mean μ = Σx/N where x = individual values of voltage and N = number of values = 10
So, μ = Σx/N
= (49.3 + 50.1 + 48.9 + 49.2 + 49.7 + 50.5 + 49.9 + 49.3 + 49.8 + 50.2)/10
= 496.9/10
= 49.69
≅ 49.7 V
So, the acceptable values of voltage are in the range μ ± σ where σ = standard deviation = 0.50 V.
So, the acceptable values of voltage are in the range 49.7 ± 0.50 V
So, minimum value = 49.7 V - 0.50 V = 49.2 V
and maximum value = 49.7 V + 0.50 V = 50.2 V
So any voltage outside the range 49.2 V ≤ x ≤ 50.2 V is rejected.
There are two values outside this range which are 48.9 and 50.5. So these two values are rejected.

Beth wants to paint her rectangular night stand that is 42 inches long and 28 inches wide. A quart of paint covers about 350 square inches. How many quarts of paint will Beth need to cover the entire night stand?
Answer:
3.36 quarts of paint
Step-by-step explanation:
In this question, we're trying to find how much paint she will need to cover the night stand.
First, we need to find the area.
Solve for the area (rectangle = l * w):
42 · 28 = 1176
Now, we know that 1 quart of paint covers 350 square inches.
To find how much paint she needs, divide 1176 by 350:
1176/350 = 3.36
This means that she needs 3.36 quarts of paint to cover her whole nightstand.
Use substitution to solve the system.

Given f(x) = 2x2 – 3x + 7, find f(2.5)
Answer:
f(2.5)=3.5
Step-by-step explanation:
f(x)=2×2-3x+7
So,
f(2.5)=2×2-3×2.5+7
=4-7.5+7
=11-7.5
=3.5

segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3). segment YZ was dilated at a scale factor of 3 from the origin. Which statement describes the pre-image?
Answer:
YZ is located at Y (0, 1) and Z (-2, 1) and is one-third the size of Y'Z'.
Step-by-step explanation:
Since Y'Z' was dilated from the origin at a scale factor of 3, you can divide its X and Y coordinates by 3 to find the coordinates of YZ.
The statement fourth "segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime" is correct.
What is dilation?The transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller. The image created by this transformation is identical to the original shape.
The question is incomplete.
The complete question is:
Segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3). segment YZ was dilated at a scale factor of 3 from the origin. Which statement describes the pre-image?
segment YZ is located at Y (0, 9) and Z (−18, 9) and is three times the size of segment Y prime Z prime.segment YZ is located at Y (0, 3) and Z (−6, 3) and is the same size as segment Y prime Z prime.segment YZ is located at Y (0, 1.5) and Z (−3, 1.5) and is one-half the size of segment Y prime Z prime.segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime.As we know, in the dilation image of the two-dimensional figure can be larger or smaller depending on the dilation factor.
We have:
segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3).
After dilation:
Y (0, 1) and Z (−2, 1)
Thus, the statement fourth "segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime" is correct.
