Answer: each eraser cost 5 dollors
Step-by-step explanation: Simplifying
25 = 5 + 4e
Solving
25 = 5 + 4e
Solving for variable 'e'.
Move all terms containing e to the left, all other terms to the right.
Add '-4e' to each side of the equation.
25 + -4e = 5 + 4e + -4e
Combine like terms: 4e + -4e = 0
25 + -4e = 5 + 0
25 + -4e = 5
Add '-25' to each side of the equation.
25 + -25 + -4e = 5 + -25
Combine like terms: 25 + -25 = 0
0 + -4e = 5 + -25
-4e = 5 + -25
Combine like terms: 5 + -25 = -20
-4e = -20
Divide each side by '-4'.
e = 5
Simplifying
e = 5

Find the height of a pyramid with
a volume of 128 cm3 if the base is
a square with a side length of
8 cm.
Answer:
height:6
if the base is a square that means all the side lengths are equivalent so it would be 8 for side lengths, and the volume is 128. plug it in with the formula to get 6
The height of a pyramid is 8cm
How to find the volume of a square based right pyramid?Supposing that:
The length of the sides of the square base the pyramid has = b units
The height of the considered square based pyramid = h units,
Then, its volume is given by: [tex]V = \dfrac{1}{3} \times b^2 \times h \: \rm unit^3[/tex]
Given;
The volume of pyramid= 128cm3
Length of side of square base= 8cm
Now,
128=1/3 x 8x8xh
128= 64/3 xh
h= 128x3/64
h=8
Therefore, the height with the volume 128cm3 will be 8cm

Jerry borrowed $4000 for 5 years at 6X simple
interest rate. What will be the total amount that
Jerry paid after 5 years?
Answer:
qqqqqqqqqq
Step-by-step explanation:
Answer:
In this question one has to look forward to the information's already given. Based on those given information's the answer to the question can be easily determined.
Principal amount = $4000
Time for which money is borrowed = 5 years
Rate of interest = 6%
Then
Amount of Interest = Principal * Rate * Time
= 4000 * 6% * 5
= 4000 * 6/100 * 5
= 40 * 30
= 1200 dollars
So the amount of interest that needs to be given is 1200 dollars. I hope the naswer and the procedure is clear enough for you to understand.

Question 7: The ratio of M's to A's cat is 5:7. Meg's cat weighs 20 kg. How
much more does Anne's cat weigh?
A) 28 kg
B) 2 kg
C) 8 kg
D) 9.3 kg
Answer: C
Step-by-step explanation: The ratio shows that Anne's cat is 2kg heavier, but Meg's cat weighs 20kg which is 4 times what the ratio shows the weight is, so the difference of the weight is also 4 times greater, which is 8kg!
The value of weight of Anne's cat will be 28 kg. Then the correct option is A.
What is the ratio?The utilization of two or more additional numbers that compares is known as the ratio.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The ratio of M's to A's cat is 5:7. Meg's cat weighs 20 kg.
Let 'x' be the weight of Anne's cat. Then the equation is given as,
5 / 7 = 20 / x
Simplify the equation, then we have
5 / 7 = 20 / x
1 / 7 = 4 / x
x = 28 kg
The value of weight of Anne's cat will be 28 kg. Then the correct option is A.

Answers to questions A and B
Answer:
A. m(arc BC) = 16°
B. m(arc BAC) = 344°
Step-by-step explanation:
From the picture attached,
AB is the diameter of the circle.
Since, measure of an arc is always same as the central angle of arc.
Therefore, m(arc AC) = m(∠ADC) = 164°
m(arc AB) = 180°
m(arc BC) = 360° - m(arc AB) + m(arc AC)
= 360° - (180° + 164°)
= 360° - 344°
= 16°
m(arc BAC) = m(arc AB) + m(arc AC)
= 180° + 164°
= 344°

What is the slop and the y-intercept on the graph?
Answer:
Slope= 2 ; y intercept= 4
Step-by-step explanation:
Slope: (y2 - y1)/(x2-x1) where x and y indicate the coordinates of two points
Slope = (4-0)/(0-(-2) = 4/2 = 2
y intercept is where the line intercepts the y axis: it happens in (0;4)
Answer:
y intercept is 4 and slope is 2

The discriminant if a quadratic equation is negative. One solution is 4 + 7i. What is the other solution? *
7 - 4i
4 - 7i
- 4 + 7i
7 + 4i
==========================================================
Explanation:
When you have a quadratic in the form ax^2 + bx + c = 0, where a,b,c are real numbers, then a negative discriminant leads to having a pair of complex roots. The roots come in conjugate pairs meaning that p+qi is one root while p-qi is the other root. The p,q are real numbers.
In the case of 4+7i being one root, we have p = 4 and q = 7, since it matches with p+qi. The other root must be 4-7i since it matches with p-qi.
In short, we flip the plus to a minus when going from 4+7i to 4-7i. All of this applies when we have a,b,c as real numbers.
If we allowed a,b,c to be complex numbers, then the roots may not necessarily come in conjugate pairs.

A deli clerk has lunchmeat formed in the shape of a cylinder with a radius of 2 inches and a height of 4 inches. He divides the lunchmeat into two equal sections by making a vertical cut as shown below. What is the shape of the cross section formed by the vertical cut?
Answer:
The shape of the cross-section is a square
Step-by-step explanation:
Given
[tex]r =2[/tex]
[tex]h = 4[/tex]
See attachment
Required
The shape of the cross-section
From the attachment, we can see that when the cylinder is cut vertically, the shape formed is a quadrilateral of equal opposite sides.
The dimension of the shape is: the height of the cylinder and the diameter of the base circle
From the given parameters, we have the radius and the height to be:
[tex]r =2[/tex]
[tex]h = 4[/tex]
The diameter (d) is:
[tex]d = 2 * r[/tex]
[tex]d = 2 * 2[/tex]
[tex]d = 4[/tex]
So, the dimension is:
[tex]h = 4[/tex] and [tex]d = 4[/tex]
Since the height and the diameter have the same lengths, then the shape is a square.
