Answers
Answer:
15200 cm²
Step-by-step explanation:
from inspection of the diagram, we can see that the prism comprises:
2 congruent triangles1 base rectangle2 congruent side rectanglesTriangle
Area of triangle = 1/2 x base x height
Given:
base = 60 cmheight = 40 cm⇒ area = 1/2 x 60 x 40 = 1200 cm²
Base rectangle
Area of a rectangle = width x length
Given:
width = 60length = 80⇒ area = 60 x 80 = 4800 cm²
Side rectangle
Area of a rectangle = width x length
Given:
width = 50length = 80⇒ area = 50 x 80 = 4000 cm²
Total area = 2 triangles + base rectangle + 2 side rectangles
⇒ total area = (2 x 1200) + 4800 + (2 x 4000) = 15200 cm²

Answer:
144 degrees
Step-by-step explanation:
The exterior angles theorem states:
The exterior angles of a triangle = the sum of the interior angles that are NOT adjacent (touching) the exterior angles.
We can use this information to set up an equation:
x=48+96
x=144 degrees
Determine whether the conclusion is valid AND explain. You want to know how the residents of your town feel about building a new baseball stadium. You randomly survey 100 people who enter the current stadium. Eighty support building a new stadium, and twenty do not. So, you conclude that 80% of the residents of your town support building a new baseball stadium.
Answers
Answer: The answer is valid, because you survey 100 people and 80 of them support building a new stadium.
Step-by-step explanation:
80% agree. 80/100 = 80%
Given triangle ABC is similar to triangle DEF, angle A measures 30 degrees, and angle F measures 50 degrees, what is the measure of angle B?
Answers
Answer:
100 degrees
Step-by-step explanation:
Since triangle ABC is similar to triangle DEF, their angles are basically the same.
All angles of a triangle have to add up to 180.
We are already given two angles: 30 and 50
Add them together: 30 + 50 = 80
Now we subtract the number from 180
180 - 80 = 100
The remaining angle has to be 100 degrees

The sum of 2 numbers is 15 and their qoutient is 2
Answers
x + y = 15------(1)
x/y = 2------(2)
y = 15 - x
put this value in eq 2
x/(15-x) = 2
x = 2 (15 - x)
x = 30 - 2x
2x + x = 30
3x = 30
x = 10
y= 15 - x
y = 15 - 10
y = 5
Solution:
Given:
x + y = 15x/y = 2Let’s simplify the second equation to find out the value of x.
x/y = 2 x = 2yNow, let’s substitute the value of x into the first equation.
x + y = 152y + y = 153y = 15y = 5Now, let’s substitute the value of y into the simplified second equation.
x = 2yx = 2(5)x = 10Hence, the value of x and y are 5 and 10 respectively.
solve system of equations:
-8x - 10y = 10
3x + 2y = 12
Answers
Answer:
x=10
y = -9
Step-by-step explanation:
-8x - 10y = 10
3x + 2y = 12
Multiply the second equation by 5
5(3x + 2y) = 12*5
15x+10y = 60
Add this to the first equation to eliminate y
-8x - 10y = 10
15x+10y = 60
-----------------------
7x + 0y = 70
Divide by 7
7x/7 = 70/7
x = 10
Now find y
3x+2y = 12
3(10) +2y = 12
30 +2y =12
Subtract 30 from each side
2y = 12-30
2y = -18
Divide by 2
2y/2=-18/2
y = -9

Sam has a party with snacks. One bowl of snacks has a mixture of fish crackers. There are 15 pretzels, 3 orange, 5 yellow, and 7 green fish crackers in the bowl.
What percent of the fish crackers are yellow?
Answers
Explanation:
Ignore the 15 pretzels. We're only focusing on the fish crackers.
3 orange + 5 yellow + 7 green = 15 total fish crackers
Of that total, 5 are yellow.
So approximately 5/15 = 1/3 = 0.333 = 33.3% of the crackers are yellow.

Answer:16 square feet
Step-by-step explanation:
add the length of the top and the bottom face them multiply the sum of those two by the perpendicular height between them and the product is to be divided by 2 : ((a+b)h)/2)
Answer:
16 ft²
Step-by-step explanation:
First you'll find the area of the rectangle forming in the trapezoid:
3 x 4 = 12
Next, you'll think logically and understand that if BC is 3 feet, EF is also 3 feet. So, you'll subtract 5 - 3 = 2, so AE and FD is 1 foot.
So, you'll now multiply to find the area of the whole trapezoid:
4 x 1 = 4
So:
4 + 12 = 16
which set of pairs represents a function? PLSS HURRY (100 POINTS)
Answers
Answer:
{(0, 0), (1, 2), (2, 4), (3, 4)}
Step-by-step explanation:
A set of ordered pairs that represent a function is one in which each different ordered pair has a unique x-coordinate (so no two different ordered pairs can have the same x -coordinate).
Therefore, {(0, 0), (1, 2), (2, 4), (3, 4)} is a function as each different ordered pair has a unique x-coordinate.
The other sets all have different ordered pairs that share the same x-coordinate and so these sets do not represent functions.
The vertical line test is also used to determine whether a graph represents a function. If the vertical line intersects the graph only once, then the curve represents a function. This test can be applied to ordered pairs, in that if two ordered pairs have the same x-coordinate but different y-coordinates, they will be on the same vertical line and therefore do not represent a function.
