Option first, option second, and option fourth are correct this expression is equivalent to the formula for a trapezoid.
What is a trapezoid?It is defined as the quadrilateral having four sides in which two sides are parallel to each other, it is a 2-dimensional geometry.
The options are:
h=2A/(b1+b2)b1=2A/h - b2b2= 2A/b1 - hb2= 2A/h - b1b1= 2A//b2 - hWe have a formula for finding the area of the trapezoid:
[tex]\rm A= \dfrac{1}{2}h(b_1+b_2)[/tex]
Make a subject h and solve for h:
[tex]\rm \dfrac{2A}{(b_1+b_2)}= h[/tex]
or
[tex]\rm h = \dfrac{2A}{(b_1+b_2)}[/tex]
[tex]\rm b_2 = \dfrac{2A}{h}- b_1[/tex]
[tex]\rm b_1 = \dfrac{2A}{h}- b_2[/tex]
Thus, option first, option second, and option fourth are correct this expression is equivalent to the formula for a trapezoid.

The y-values go up by the square of the x-value (22 = 4). Therefore, the ordered pairs represent a quadratic equation.
The y-values go up by the square of the x-value (22 = 4). Therefore, the ordered pairs do not represent a quadratic equation.
Since the differences between the differences of the y-values is not consistent, the ordered pairs do not represent a quadratic equation.
Since the differences between the x-values is 2 and the differences between the y-values is 4, that means that the differences between the differences

Answer:
56 [tex]in^2[/tex]
Step-by-step explanation:
We can first break this down into 2 smaller rectangles.
1x2x4 rectangle
4x3x4 rectangle.
Then we can find out the area of each, and we get 8+48 = 56.
You also could find this out by subtracting the area that is missing.
Answer:
The volume of the container is 56 in^3
Step-by-step explanation:
To solve, I split this figure vertically at the corner between the two steps. We know that the formula for volume of a container is V= l*w*h. The first, smaller portion of the container has a length of 4, a width of 1, and a height of 2. 4*1*2= 8 in^3
The second, larger portion of this container has a length of 4, (look at the side of the first portion), a width of 3, (4-1=3), and a height of 4. 4*3*4= 48 in^3.
Finally, add together the volumes of the two portions and that is the volume of the whole figure. V= 56 in^3
Find the median of the data in the dot plot below.
Answer:
40
Step-by-step explanation:
The median is the middle value of the data arranged in ascending order. If there is no exact value in the middle then it is the average of the values either side of the middle.
The data is arranged in ascending order within the dot plot
There are 10 values in the data set
Thus the median is between the fifth and sixth values.
Counting from the left (35)
The fifth value = 39 and the sixth value = 41, thus
median = [tex]\frac{39+41}{2}[/tex] = [tex]\frac{80}{2}[/tex] = 40
Answer:
Step-by-step explanation:
Data:
35 , 38, 38 , 39 , 39, 41, 42 , 43, 43, 44
Total number of data = 10
Number of data is even. so, median is the average of (n/2)th term & ([tex]\frac{n}{2}+1[/tex] ) middle term,
Median = average of 5th and 6th term
= (39 + 41)/2 = 80/2 = 40

Answer:
<Q= 15/36=0.42
<R= 36/15=2.4
Step-by-step explanation:
When doing trig you have to remember, "SOH CAH TOA"
Since you're looking for the tangent for angles Q and R, it would be the opposite over adjacent which is what "TOA" stands for. So, opposite of Q is 15 and adjacent to Q is 36, so you get 15/36. Opposite of R is 36 and adjacent is 15 so you get 36/15.
What is the volume of the square pyramid shown to the nearest tenth? The figure is not drawn to scale. width of 16 and a length of 17 A. 1,280.0 ft^3 B. 85.3 ft^3 C. 1,920.0 ft^3 D. 3,840.0 ft^3
The volume of the pyramid is 1,280 cubic feet. Thus, the correct option is A.
What is the volume of the pyramid?Let h be the height of the pyramid, l be the slant height, and A be the base area of the pyramid. Then the volume of the pyramid will be given as,
Volume = (1/3) × A × h
The slant height is given as,
l² = (half of the side)² + h²
Given that:
Slant height, l = 17 ft
Side length, a = 16 ft
The height of the pyramid is calculated as,
17² = (16/2)² + h²
h = 15
The volume of the pyramid is calculated as,
V = 1/3 x 16 x 16 x 15
V = 256 x 5
V = 1,280 cubic feet
Thus, the correct option is A.

we can multiply the 4 on the outside of the parenthesis to all the terms. Multiplying, we get
[tex](r^{-12}s^8t^4)[/tex]

Step-by-step explanation:
→ First work out volume of pyramid using the formula [tex]\frac{lwh}{3}[/tex] where 'l' is the length, 'w' is the width and 'h' is the height
[tex]\frac{lwh}{3}[/tex] ⇔ [tex]\frac{4*8*10}{3}[/tex] ⇔ [tex]\frac{320}{3}[/tex] ⇔ 320 ÷ 3 = 106.666666667

Density = Mass ÷ Volume
Density = 50 ÷ 106.666666667
Density = 0.46875 to 1 decimal place is 0.47

Answer:
x = 0, x = 4
Step-by-step explanation:
12x - 21 = 5x + 7(x - 3)
First, foil out the right side --> 5x² - 15x + 7x - 21, which simplifies down to 5x² - 8x - 21.
Move the 12x - 21 to the right side by subtracting --> 0 = 5x² - 20x.
Factor out a 5x --> 0 = 5x(x - 4)
If you want to solve for x, set 5x = 0 and x - 4 = 0.
For 5x = 0, divide both sides by 5 to isolate the x --> x = 0/5, which simplifies down to x = 0.
For x - 4 = 0, add 4 to both sides to isolate the x --> x = 0 + 4, which simplifies down to x = 4.
Plug the values back into the original equation to check if it works
12(0) -21 = 5(0) + 7((0) - 3) --> -21 = -21
12(4) - 21 = 5(4) + 7((4) -3) --> 27 = 27

An exponential function f(x)= ab^x passes through the points (0,10) and (3,1250). What are the values of a and b?
a = I know it’s 10
b = ?
Answer:
a = 10 and b = 5
Step-by-step explanation:
We write out f(x)= ab^x for x = 0 and x = 3 to create two equations in a and b that must be solved simultaneously:
(0, 10): 10 = a*b^0
This tells us that 10 = a*1, or a = 10.
(3, 1250): 1250 = a*b^3 => 10*b^3, or
1250 = 10*b^3, or
125 = b^3. Taking the cube root of both sides, we obtain b = 5.
a = 10 and b = 5
the graph of y=f(x) is shown below. find all the values of x where f(x)=8
Answer:
x = 4
Step-by-step explanation:
Find 8 on the y-axis. Draw a horizontal line through y =8. Determine the x value for which the graph intersects this horizontal line y = 8. It is x = 4
The value of x when f(x) = 8 according to the graph is; 4.
According to the graph;
To determine the value of x when f(x) = 8.We must plot a line of the equation; y = 8.
This line of y = 8 results in an horizontal line.The point at which the horizontal line, y = 8 intersects the given graph has an x coordinate.Ultimately, the x coordinates of this point is 4 and hence, the value of x when f(x) = 8 is 4.

Slim Johnson was usually the best free-throw shooter on his basketball team. Early in the
season, however, he had made only 9 of 20 shots. By the end of the season, he had made all
the additional shots he had taken, thereby ending with a season record of 3:4. How many
additional shots had he taken?
Answer:
24
Step-by-step explanation:
(9 + x)/(20 + x) = 0.75
Solve that for x, the number of additional free throws taken.
9 + x = 15 + 0.75 x
0.25 x = 6
x=24
The required number of additional shots that were shot is 24.
Given that,
He had made only 9 of 20 shots. By the end of the season, he had made all the additional shots he had taken, thereby ending with a season record of 3:4.
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Let the extra shots be x,
Now, according to the question,
Number of shots will be 9 + x and 20 + x,
And their ratio is 3:4
9 + x / 20 + x = 3 / 4
[9 + x] × 4 = 3 [20 + x]
36 + 4x = 60 + 3x
x = 60 - 36
x = 24
Thus, the required number of additional shots that were shot is 24.

Solve the simultaneous equations. You must show all your working to find x and y. 1/2x -3y = 9 5x y + y = 28
Answer:
[tex]\huge\boxed{x = 6 , y = -2}[/tex]
Step-by-step explanation:
[tex]\sf \frac{1}{2} x - 3y = 9-----------(1)\\5x + y = 28 ----------(2)[/tex]
Taking equation (1)
[tex]\sf \frac{1}{2} x -3 y=9[/tex]
Multiplying both sides by 2
[tex]\sf x-6y = 18[/tex]
Adding 6y to both sides
[tex]\sf x = 18+6y[/tex]
Putting this in (2)
5(18+6y) + y = 28
5(18+6y) + y = 28
90 + 30y+y = 28
31y+90-28 = 0
31 y + 62 = 0
31y = -62
Dividing both sides by 31
y = -2
Now,
x = 18 + 6y
x = 18+6(-2)
x = 18-12
x = 6
