What is the area of the trapezoid shown below?
The trapezoid has two bases. Base one is labeled fifteen feet. Base two is labeled ten feet. The height of the trapezoid is labeled eight feet.
200 ft2
150 ft2
120 ft2
100 ft2
Answer:
Step-by-step explanation:
The area formula for a trapezoid would be b1+b2/2*height
So, 15+10/2*8
15+10=25
25/2= 12.5
12.5x8= 100 ft2
Therefore, Area equals 100 ft2
Answer:
100 ft.^2
Step-by-step explanation:
A = a+b ÷ 2 • h
A = 15 + 10 ÷ 2 • h
A = 25 ÷ 2 • 8
100 = 25 ÷ 2 • 8

This situation describes the AP with:
The first term of a₁ = 1Common difference d = 2The nth term of AP is:
aₙ = a₁ + (n - 1)dThe sum of the first n terms:
Sₙ = (a₁ + aₙ)*n/2S₁₀ = (1 + 1 + 9*2)*10/2 = 20*5 = 100What is the area of the triangle.
Answer:
4.44 cm²
Step-by-step explanation:
We can find the area of the outlined triangle by plugging its dimensions into the triangle area formula.
\(A = \frac{1}2 \times \text{base} \times \text{height}\)
\(A = \frac{1}2 \times 6 \times 1.48\)
\(\boxed{A = 4.44 \text{ cm}^2}\)
Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.
Step-by-step explanation:
State the inequality that describes the region drawn in the number plane.
Answer:
y > -2x - 1
Step-by-step explanation:
The slope is -2 because it goes down 2 every time it goes over 1
The y intercept is -1
Therefore the answer is y > -2x - 1

Which inequalities would have an open circle when graphed? Check all that apply.
t Less-than-or-equal-to 25
-2.5 Less-than-or-equal-to m
x > 5.4
One-half less-than x
x > 0
An open circle is used to graph strict inequalities, which means the inequality does not include the value at the boundary. The inequalities that would have an open circle when graphed are:
x > 5.4
One-half less-than x
x > 0

Find the arc length of the semicircle.
Answer:
9π, or 28.26
Step-by-step explanation:
The Arc of the semicircle is the circumference of half a circle.
The radius of the semicircle is 9, and the circumference of a circle is 2πr, so it is 2π9 = 18π. since this is a semicircle, it is half of that, so 9π, or 28.26, since π is 3.14 here

Answer the question as an multiple choice.
Answer: i think its the first one 2/3
Answer:
2/3
Step-by-step explanation:
it starts off as 2:3 right? so the 3 is light soy sauce. if you want to turn the right soy sauce into 1 cup you have to divide 3 bye 3 which gives you one. then you also divide by 3 on the other side. that would be 2 divided by 3. 2 divided by 3 is the same as 2/3. so your answer is 2/3.
