The hight of a regular quadrilateral prism is h=13cm and its lateral area is 624 cm squared. Find the surface area of the prism
Answer:
912 cm^2
Step-by-step explanation:
The total surface area of a 3-dimensional object is the sum of the areas of the faces or surfaces of a 3-dimensional object
Lateral area of a prism = 4 x height x sides
624 = 4 x 13 x s
s = 12
Surface area = 2 x 12^2 + 624
(2 x 144) + 624 = 912 cm^2

If you spin the spinner once, determine the probability and the likelihood of spinning with colors red, orange, blue or green, red blue orange or green, not red
Answer:
Step-by-step explanation: There are 12 colours on a spinner,
Probability of red,orange, blue or green = 1/12×4 =4/12
=1/3
Probability of red,blue, orange or green= 1/12×4=1/3
Probability of not red= 1-1/12
=11/12
how to solve y=-5/2x+4, Y=-1 using substitution
(i need the steps not just the answer)
Answer:
Step-by-step explanation:
- Since y = -1, we will substitute the y variable in the equation for -1.
-1 = -5/2x + 4
- Take away 4 from both sides in order to find out what x equals so we can substitute it.
5 = -5/2x
- turn it into a positive by multiplying each side by -1.
-1(-5 = -5/2x) =
5 = 5/2x
- Divide each side by 5.
1 = 1/2x
- Multiple both sides by 2.
2 = x
- Substitute the variables.
x = 2
y = -1
-1 = -5/2(2) + 4
what value of x makes this equation -5/2x + 1 = x + 3 true
Answer:
x = -4/7
Step-by-step explanation:
-5/2x + 1 = x + 3
-7/2x = 2
(-2/7)-7/2x = 2(-2/7)
x = -4/7
James cut out four parallelograms, the dimensions of which are shown below. Parallelogram 1 length: 12 in. width: 15 in. diagonal: 20 in. Parallelogram 2 length: 16 in. width: 30 in. diagonal: 34 in. Parallelogram 3 length: 20 in. width: 21 in. diagonal: 29 in. Parallelogram 4 length: 18 in. width: 20 in. diagonal: 26 in. James put the parallelograms together so one vertex from each paper exists on a point, as shown in the circle. 4 parallelograms are put together so that one vertex from each paper exists on a point. Which statement explains whether or not the parallelgrams can be put together so each occupies one-quarter of the area of the circle without overlapping any other pieces? Check all that apply. The quadrilaterals can be placed such that each occupies one-quarter of the circle. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 1 do not form right angles. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 2 do not form right angles. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 3 do not form right angles. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 4 do not form right angles.

The equation of a line is y=mx+ 4. What is the value of m if the line passes through point (−3, 7)?
Answer:
m= -1
Step-by-step explanation:
plug in the coordinate (-3, 7) into y=mx+4 where (x, y)
7=-3m+4
solve for m and you get -1
:)
Answer:
[tex]\huge\boxed{m=-1}[/tex]
Step-by-step explanation:
We have
[tex]y=mx+4\\\\(-3,\ 7)[/tex]
Put the coordinates of the given point to the equation of the line:
[tex](-3,\ 7)\to x=-3,\ y=7\\\\7=-3m+4\qquad|\text{subtract 4 from both sides}\\\\7-4=-3m+4-4\\\\3=-3m\qquad|\text{divide both sides by (-3)}\\\\\dfrac{3}{-3}=\dfrac{-3m}{-3}\\\\-1=m\to m=-1[/tex]

The expressions 3¹⁰/3², (3⁴)², and (3·3)⁴ are equivalent to the given expression. which is the correct answer would be options (B), (D), and (E).
What are exponential expressions?Exponential expressions, as the name indicates, involve exponents. We already know that the exponent of a number (base) specifies how many times the number (base) has been multiplied. To answer the exponential expressions, we may need to apply the relationship between exponents and logarithms.
As per option (B), we have
3¹⁰/3²
3¹⁰⁻²
Apply the subtraction operation in the exponent
3⁸
As per option (D), we have
(3⁴)²
3⁴ˣ²
Apply the multiplication operation in the exponent
3⁸
As per option (E), we have
(3·3)⁴
(3²)⁴
3⁴ˣ²
3⁸
Thus, the expressions 3¹⁰/3², (3⁴)², and (3·3)⁴ are equivalent to the given expression.
Hence, the correct answer would be options (B), (D), and (E).

[tex]x^{2}[/tex]+8x+7
Answer:
(x + 1)(x + 7)
Step-by-step explanation:
Assuming you require the expression factored
x² + 8x + 7
Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)
The factors are + 1 and + 7 , since
1 × 7 = 7 and 1 + 7 = 8 , then
x² + 8x + 7 = (x + 1)(x + 7) ← in factored form
Max surveyed 100 of the 200 7th graders that attend his school to help determine new lunch choices in the lunch room. He has come up with these findings.
Which statement is supported by the information in his graphs?
A
It can be inferred that on the days that students are offered pizza and salad, 70% of students are pleased with the offerings.
B
It can be inferred that about the same number of students get a salad as the number of students that like cheeseburgers and tacos combined.
C
It can be inferred that pizza and chicken nuggets should be the only meals offered in the cafeteria to please the most students each day.
D
It can be inferred that if the lunchroom offered cheeseburgers and tacos on the same day, every student would get a tray that day.
Answer:
It can be inferred that pizza and chicken nuggets should be the only meals offered in the cafeteria to please the most students each day.
Step-by-step explanation:
From barchart, we can observe that ; the both pizza and chicken nugget have the highest number of 7th grade students who prefer them. Hence, with these numbers, most students will be pleased if these are the food options served each day.

SHOW YOUR WORK HERE
Answer:
Part A: 40% are pennies
Part B: NIckels 10, Quarters 20, Pennis 20
Answer:
Part A: pennies are 40% of the jar
Part B :
Nickels: 10
Quarters: 20
Pennies: 20
Step-by-step explanation:
Part A: since the nickels and quarters make up 60% of the jar the pennies make up the other 40%.
Part B:
Nickels: 20 percent of 50 (the amount of coins in the jar) is 10
Quarters & Pennies (since they have the same percentage): 40 percent of 50 is 20
