A triangular prism. The rectangular sides are 12 feet by 3 feet, 12 feet by 5 feet, and 12 feet by 4 feet. The 2 triangular sides have a base of 3 feet and height of 4 feet.
The area of each triangular base is:
A = 1/2(b)(h)
A = 1/2(3)(4)
A =
ft2
There are two bases, so total base area is
ft2.
The lateral area is:
A = (12)(3) + 12(5) + 12(4)
A =
ft2
The total surface area is
ft2.

Do the calculation below
6(18 + 14)
Answer:
Explained below...
Step-by-step explanation:
First, recognize the acronym PEMDAS, which stands for:
P - Parenthesis
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
So, as there are parenthesis, that will be your first step in the expression.
6(18 + 14) --> 6(32)
Now, you will find the next step in PEMDAS, which would be multiplication.
6 * 32 = 192.
So, your answer for the equation is 192.
Hope this helps! :)
Answer:
6(18 + 14) = 192

Answer:
C
Step-by-step explanation:
Answer:
c)
Step-by-step explanation:
so we know that the total amount of students in said school is 180, which means that the total amount of girls in this school cannot be greater than 180
with that, let us get to solving these equations to see which one is less than 180-
a) 85/10*180=1530>180
b) 850/100*180=1530>180
c)0.85*180=153
'c' is the only answer choice less than 180>153
another way to solve this would be to focus solely
on answer choice 'c'-
so 85% of the school is female and 85% as a fraction is 0.85, and we need to find the total amount of girls that attend said school and the only way to do that is to multiply-
0.85*180=153>180
good luck :)
i hope this helps

Answer:
11.6 km²
Step-by-step explanation:
Divided it into two shapes, a triangle and a rectangle. Then find the area for each. The triangle is 4 km long and 2.2 km wide. The rectangle is 1.8 km wide and 4 km long.Solve the area for the triangle. The equation l · w ÷ 2=A will help. So, the equation would be 4 · 2.2 ÷ 2=4.4Then, solve the area for the rectangle by using the equation l · w=A. 1.8 · 4=7.2Add them together. 4.4+7.2=11.6Final answer - 11.6 km²Write an equation of a parabola that has two x-intercepts and a minimum vertex.
A. y = −x^2 − 2
B. y = x^2 − 2
C. y = −x^2 + 2
D. y = x^2 + 2
Frankie and Marcel are picking up apples. Frankie has 18 apples, which is 4 times plus 2 more apples then Marcel has. How many apples does Marcel have?
Answer:
Marcel has 4 Apples
Step-by-step explanation:
1. I see that it is plus two so I get rid of that and subtract two from eighteen.
2. Now I see that Marcel has 4 times less than 16 and 16 divided by 4 is 4.
Marcel has 4 apples.
In a circle graph, 36% represents what angle?
1. 33°
2. 130°
3. 95°
4. 65°
Answer:
2. 130
Step-by-step explanation:
There are 360° in a full circle. 36% of 360 = 0.36 360 = 129.6° which rounds to 130°.

Not drawn to scale
a. * = 12
b. x =18
0.
36
d x = 54
Answer:
I believe x = 12
Step-by-step explanation:
If the triangles were similar then they would have the same angle measures.
Steps:
Add angle K and L: 90 + 54 = 144
Subtract the added angles from 180 to find angle J: 180 - 144 = 36
Angle J is similar to angle X so, divide 36 by 3: 36/3 = 12
x = 12

A student is asked to find the length of the hypotenuse of a right triangle. The length of one leg is 38 centimeters, and the length of the other leg is 29 centimeters. The student incorrectly says that the length of the hypotenuse is 8.2centimeters. Answer parts a and b.
Find the length of the hypotenuse of the right triangle to the nearest tenth of a centimeter.
The length of the hypotenuse of the right triangle to the nearest tenth of a centimeter is ..... cm
(Round to the nearest tenth as needed.)
Answer:
1,142.5 or 1,143
Step-by-step explanation:
Part A: Start by writing out the equation a2 + b2 = c2. Since both sides a and b are known, fill it in. So, now it is 38 squared + 29 squared = c2. Next, you have to find the square roots for both sides, or legs. For 38 squared, it will be 38 x 38 = 1,444. For 29 squared, it will be 29 x 29 = 841. Now that we both legs, we add that together: 1,444 + 841, which equals 2,285. Then, you need to divide 2,285 by 2, which is 1,142.5
Since you need to round, it would be 1,143.
Part B: 1,143

Please help me if you can thank you. For question A the answer is 5000 brochures. My question is how did they get that answer?
pls NO links or spam comments it’s really annoying
Answer:
By writing an equation 0.50x + 900 = 0.38x + 1500 and solving (you can also write a system of equations)
Step-by-step explanation:
The equation for company A's price is y = 0.50x + 900 ($0.50 per brochure plus flat fee of $900)
The equation for company B's price is y = 0.38x + 900 ($0.38 per brochure plus flat fee of $1500)
The goal is for the cost (y) to be the same so these equations would both have to be equal to each other. Once solving for x you will get 5000 brochures.

Answer: For the first one, 12.5% chance
Step-by-step explanation:
The probability of flipping a coin and getting tails is 50%. Then, if you were to flip two coins and get both tails, you would have to divide the 50% by 2, which is equals to 25% of flipping two coins and getting them both tails.
So now we know...
Flipping one coin gives you 50% tails and 25% of flipping two coins and getting two tails
So now, we do it again with the third coin. We would divide the 25% by 2, which will get us to a 12.5% of getting all tails, or in fractions, 1/8
