Simon says that to find the area of a trapezoid, you can multiply the height by the top base and the height by the bottom base. Then add the two products together and divide the sum by 2. Is Simon correct? Complete the explanation.
Answer:
Yes, Simon is correct.
Step-by-step explanation:
A trapezoid refers to a quadrilateral that is convex in shape; as such it has no equal sides and no parallel sides.
Let the height of a trapezoid be h.
Let the top base of a trapezoid be b1.
Let the bottom base of a trapezoid be b2.
[tex] Area \; of \; trapezoid = \frac {1}{2} * (Sum \; of \; nonparallel \; sides) * height [/tex]
Therefore, [tex] Area \; of \; trapezoid = \frac {1}{2} * (b_{1} + b_{2}) * h [/tex]
[tex] Area \; of \; trapezoid = \frac {1}{2} * (b_{1}h + b_{2}h) [/tex]
[tex] Area \; of \; trapezoid = \frac {b_{1}h + b_{2}h}{2} [/tex]
Hence, to find the area of a trapezoid, you will multiply the height by the top base and the height by the bottom base. Then you add the two products together and divide the sum by 2.

Step-by-step explanation:
From 1-10 You can see the numbers going from 0-8 on the left side except you repeat the number 4 twice then proceed. Then on the right side you do it backwards but instead you use the 2 times tables and you’re going to want to work your way from bottom to top and then when you reach to 0 which is the number 10 you repeat the 2 times tables again.

Answers
A. 10
B. 5
D. 15
C. 20
Answer:
D: 15
Step-by-step explanation:
Ok, by looking at the first equation, you know that one triangle equals 10. By looking at the second one, you see that two circles equal 10, since 20- triangle(10) equals 10. This means a circle has to equal 5. looking at the third one, the answer is 13, and a circle is 5, so 13-5=8. Two squares equal 8. the last one shows one triangle, one circle, and a half square. From the third one, you know that one square equals 4, so a half square equals two. I do not know why this logic doesn't match with the answers, since 10(triangle) plus 5(circle) and 2(half square) is 17, but in terms of what makes sense and just matching it with the answers provided, I say go with the third option.

The weights in pounds of 6 members of a basketball team are 125, 136, 150, 119,
and 143. Find the mean and the median *
Answer:
Mean:(137.2)
Median:(139.5)
Step-by-step explanation:
Mean = (125+136+150+119+143) divide by six(6)
= 823/6 = approx 137.2
Median = for the median, you will arrange the numbers in other. from smaller to the bigger number.
119,125,136,143,150, 150. so 136 & 143 is the middle number.
so you will add the middle number and divide by 2.
that is 136+143/2 = 139.5.

A line passes through the point 2,1 and has a slope of -3/5. Write an equation for this line
Answer:
y = -3/5x + 1.3
Step-by-step explanation:
y = mx + b
m: slope
b: y-intercept
First, let's substitute in the values.
Point: (2, 1)
Slope: -3/5
y = mx + b
(1) = (-3/5)(2) + b
1 = -0.3 + b
1 + 0.3 = -0.3 + b + 0.3
b = 1.3
Now, let's add the slope and y-intercept to the equation.
y = mx + b
m = -3/5
b = 1.3
y = -3/5x + 1.3
Hope this helped! <3
An angle θ on the unit circle has a sine of 14. What is the value of cosθ?
Given:
An angle θ on the unit circle has a sine of [tex]\dfrac{1}{4}[/tex].
To find:
The value of cosθ.
Solution:
We have,
[tex]\sin \theta=\dfrac{1}{4}[/tex]
Since sinθ is positive, therefore, θ lies in first or second quadrant.
We know that,
[tex]\sin^2 \theta +\cos^2 \theta =1[/tex]
[tex](\dfrac{1}{4})^2+\cos^2 \theta =1[/tex]
[tex]\dfrac{1}{16}+\cos^2 \theta =1[/tex]
[tex]\cos^2 \theta =1-\dfrac{1}{16}[/tex]
Taking square root on both sides.
[tex]\cos \theta =\pm \sqrt{\dfrac{16-1}{16}}[/tex]
[tex]\cos \theta =\pm \dfrac{\sqrt{15}}{4}[/tex]
Therefore, the value of cosθ is either [tex]\dfrac{\sqrt{15}}{4}[/tex] or [tex]-\dfrac{\sqrt{15}}{4}[/tex].
Lori tosses a ball into the air. The equation y = –16(x – 1)^2 + 25 models the height, y, in feet, of the ball after x seconds. What is the maximum height the ball reaches?
1 ft
9 ft
16 ft
25 ft
Answer:
25 ft
Step-by-step explanation:
Got it right on EDG2020
The ball will reach the maximum height in a second. Then the maximum height the ball reaches will be 25 ft.
What is differentiation?The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.
Lori tosses a ball into the air. The equation models the height, y, in feet, of the ball after x seconds.
[tex]\rm y = -16(x - 1)^2 + 25[/tex]
Differentiate the equation with respect to x, then we have
[tex]\begin{aligned} y' &= 0\\\\\dfrac{d}{dx}[-16(x - 1)^2 + 25] &= 0\\\\ -32(x-1) &= 0\\\\x &= 1 \end{aligned}[/tex]
Then the maximum height the ball reaches will be
[tex]\rm y = -16(1 - 1)^2 + 25\\\\y = -16*0^2 + 25\\\\y = 25[/tex]
Then the maximum height the ball reaches will be 25 ft.

What is the value of x for the equation 4x – 2y = 6 if y= -3?
Answer:
x = 0
Step-by-step explanation:
Let's divid both sides of the equation by 2 first, so we don't have as much work to do in the next step:
[tex]4x-2y=6\\2x-y=3[/tex]
Substituting -3 for y:
[tex]2x-(-3)=3\\2x+3=3\\2x=0\\x=0[/tex]

b. Mills works as a construction worker. He makes a salary of 54,200 a year. After
this year his boss decided to give him a 3.5% raise. What is his new salary?
Answer:
$56,097
Step-by-step explanation:
First, we have to figure out how much his raise was, so we can convert 3.5% directly to a decimal:
3.5% = 0.035
Then we find
3.5% of 54,200 = 0.035 x 54,200 = 1,897
1,897 + 54,200 = 56,097
So, Mills new salary is $56,097
hope this helps:)
