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
Which of the following expressions is equivalent to 3x + 3x + 5 + 5? 3( x + 10) 2(6 x + 10) 3( x + 5) 2(3 x + 5)
Answer: 2(3 x + 5)
Explination: 2(3x) = 6x which is also 3 + 3
2(5) = 10 which is also 5+5

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.

a number is chosen at random from 1 to 25. find the probability of selecting a number less than 3?
Answer: Because we are finding the probability of selecting a number less than three, you are left with two options. The answer would be either one, or two.
If you were to also use three it wouldn´t be correct because three is equivalent to three.

Alejandro made an error in the steps below when determining the equation of the line that is perpendicular to the line 4x – 3y = –8 and passes through the point (3, –2).
Answer:
y=-3/4x+1/4
Step-by-step explanation:
This is the concept of equations of graphs; We are required to calculate for the equation if the line that is perpendicular to the line 4x-3y=-8 and passes through point (3,-2).
Here we proceed as follows;
4x-3y=-8 can be written in he form y=mx+c as follows;
-3y=-4x-8
thus;
y=4/3x+8/3
The slope of the line perpendicular to this is -3/4. Thus using point (3,-2) the equation will be as follows;
-3/4=(y--2)/(x-3)
-3/4(x-3)=y+2
y+2=-3/4(x-3)
y+2=-3/4x+9/4
thus;
y=-3/4x+1/4
the answer is:
y=-3/4x+1/4
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.

Solve the equation using the zero-product property 4X(X + 4) = 0
Answer:
X = 0 or X = -4
Step-by-step explanation:
4X(X + 4) = 0
4 = 0 or X = 0 or X + 4 = 0
Since 4 = 0 is false, we eliminate that equation.
X = 0 or X + 4 = 0
X = 0 or X = -4

The two leg lengths of a triangle are 21 and 28 ft. What is the length of the hypotenuse?
Answer:
588
Step-by-step explanation:
Answer
The length of the hypotenuse is 35 feet.
Explanation
This is the formula to find the hypotenuse.
[tex]l^{2} + l^{2} = h^{2}[/tex]
One leg is 21 feet. The other is 28 feet. Now insert those into the formula.
[tex]21^{2} + 28^{2} = h^{2}[/tex]
[tex]h^{2}=1225[/tex]
Now to find what h is you should find the square root of 1225.
[tex]\sqrt{1225} =35[/tex]
So the length of the hypotenuse is 35 feet.

Evaluate: f(x) = 2x^2 + 6x - 4; f(-5) *
[tex]f(x)=2x^2+6x-4\\[/tex]
Find f(-5) by substituting x = -5 in the equation.
[tex]f(-5)=2(-5)^2+6(-5)-4\\f(-5)=2(25)-30-4\\f(-5)=50-34\\f(-5)=16[/tex]
Therefore, the answer is f(-5) = 16
Answer:
f(-5)=126
Step-by-step explanation:
what you would do first is plug -5 in for x which would give you the equation of f(-5)= 2(-5)^2 + 6(-5) -4
then you multiply the negative 5 and you will get
f(-5)= -10^2 + 30 -4
remove that square by multiplying -10 by -10 and you will get
f(-5)= 100 + 30 -4
combine like terms and you will get
f(-5)=126
