Answer:
56
Step-by-step explanation:
by the formula at the bottom, it would be 1/2h(b1 + b2)
so h = height and the height is 7 feet. 1/2 of 7 feet is 3.5
b1 would be 12 feet, and b2 would be 4 feet. so first let’s do the (. )
12 + 4 = 16
now the problem is 3.5(16)
3.5 x 16 = 56
now i just went off the formula, but i think that’s right. good luck!
Answer:
56
Step-by-step explanation:
Area of a Trapezium = 1/2 × sum of parallel sides× height
= 1/2× (12+4)×7
=1/2 × 16×7
= 8×7
= 56

Determine which lines are parallel and which are perpendicular. Explain your reasoning.
Answer:
Parallel: a and b, p and q, p and r, q and r
PErpendicular: p&a, p&b, q&a, q&b, r&a, r&b
Step-by-step explanation:
Parallel lines have the same slope so both of the lines would be going in the same direction and will never cross each other.
Perpendicular lines cross at a 90 degree angle.
Technically you do not know if q&a and q&b are perpendicular because you do not know if there is a 90 degree angle
Answer:
Parallel lines are equally spaced out in the same direction so it would be p,q, and r, Purpendicular Lines intersect at a 90 degee angle so it would be q and a, q and b, r and b, and r, and so on

evelyn packed this box with 1-inch cubes. which expression does NOT show how evelyn can find the volume of the box
Answer:
[tex]Volume = 2 + 3+6[/tex]
Step-by-step explanation:
Given
[tex]Length = 2[/tex]
[tex]Width = 3[/tex]
[tex]Height = 6[/tex]
See attachment for box
Required
Which does not represent volume?
The volume is calculated as:
[tex]Volume = Length * Width * Height[/tex]
This gives:
[tex]Volume = 2 * 3 * 6[/tex] ---- (b) represents volume
Multiply 2 and 3
[tex]Volume = 6 * 6[/tex] ---- (d) represents volume
The above product can be converted to addition, as:
[tex]Volume = 6 + 6 + 6 + 6 + 6 + 6[/tex] ---- (a) represents volume
Hence:
[tex]Volume = 2 + 3+6[/tex] --- does npot represent volume

Given:
The diagram.
To find:
(a) [tex]m\angle SQT[/tex]
(b) [tex]m\angle QRW[/tex]
(c) [tex]m\angle PRV[/tex]
Solution:
(a)
If two lines intersect each other at a point, then the vertically opposite angles are equal.
[tex]m\angle SQT = m\angle PQR[/tex] (Vertically opposite angles)
[tex]m\angle SQT = 36^\circ[/tex]
Therefore, the measure of angle SQT is 36 degrees.
(b)
If a transversal line intersect two parallel lines, then the alternate interior angles are equal.
[tex]m\angle QRW = m\angle PQR[/tex] (Alternate interior angles)
[tex]m\angle QRW = 36^\circ[/tex]
Therefore, the measure of angle QRW is 36 degrees.
(c)
It is given that the angles PRV and angle PRQ are congruent.
Let the measures of angle PRV and angle PRQ are x degrees.
[tex]m\angle PRV+m\angle PRQ+m\angle PQR=180^\circ[/tex] (Adjacent interior angles are supplementary)
[tex]x+x+36^\circ=180^\circ[/tex]
[tex]2x=180^\circ -36^\circ[/tex]
[tex]2x=144^\circ[/tex]
Divide both sides by 2.
[tex]x=\dfrac{144^\circ}{2}[/tex]
[tex]x=72^\circ[/tex]
Therefore, the measure of angle PRV is 72 degrees.

Answer:
n = 4
Step-by-step explanation:
The expression must equal 6. Thus, we can make an equation:
3n - (2 + n) = 6
We distribute the negative and take away the parenthesis:
3n - 2 - n = 6
We combine like terms:
2n - 2 = 6
We add 2 to both sides to isolate n:
2n = 8
We divide each side by 2:
n = 4.

A farmer sells 8.6 kg of Pierce an apple at the Farmers Market two fifths of the wait is pears and the rest is apples how many kilograms of apples did she sell at the Farmers Market
Answer:
Weight of Pears = 3.44 Kgs
Weight of Apple = 5.16 Kgs
Step-by-step explanation:
Given
The total weight of the Pears and the apple is 8.6 Kg
Out of this total weight, the weight of the pears is 2/5
Hence, weight of the Pears is 2/5 * 8.6 = 3.44 Kg
Weight of the Apple is equal to 8.6 -3.44 Kgs = 5.16 Kgs
Weight of Pears = 3.44 Kgs
Weight of Apple = 5.16 Kgs

Lori had $126.89 in her bank account. She deposited $21.49 into it and then wrote a check for her car repairs for $156.61.
What was the ending balance in her account?
O -$51.21
O $8.23
O $8.23
O $51.21
What is the answer?
Answer:
-8.23
Step-by-step explanation:
If Lori had $126.89 in her bank account and she deposited $21.49, she would be adding that to the amount of money in her bank account.
126.89+21.59= 148.48
Then subtract the amount of money the repairs costed.
148.48 - 156.61 = -8.23
Therefore Lori would have a balance of -$8.23.
Answer:
Lori had $126.89 in her bank account.
She deposited $21.49 into it and then wrote a check for her car repairs for $156.61
126.89+ 21.49=148.38
148.38-156.61=−8.23
the answer is -8.23

1 and 2 are complementary angles. The measure of 1 is 54 . The measure of 2 is 6(x +1). Find the value of x.
Answer:
x = 5
Step-by-step explanation:
Complementary angles are two angles that add up to 90 degrees. 90 - 54= 36, so 6(x+1), or 6x+6 = 36. You subtract 6 from both sides to get 6x=30, then divide by 6 on both sides to get x=5. So the answer would be x=5.

In this table, Davis recorded how far he could throw balls of different weights.
He modeled the data with a linear best-fit function. He can throw a certain ball 30 feet. Approximately how many pounds would this ball weigh?
a. 7.5 pounds
b. 8.1 pounds
c. 8.6 pounds
d. 9.1 pounds
Answer:
Option C
Step-by-step explanation:
By using linear best fit calculator for the given data,
Equation of the line of best fit will be,
y = -5.2514x + 74.94413
Here, x = Weight of the ball
y = Distance thrown by Davis
Now substitute y = 30 feet to calculate the weight (x) of the ball.
30 = -5.2514x + 74.94413
5.2514x = 74.94413 - 30
5.2514x = 44.94413
x = 8.5585
x ≈ 8.6 pounds
Therefore, David can throw a ball 30 feet weighing 8.6 pounds.
Option C will be the answer.

The stock was worth $85. What will the stock be worth in 7 years? WhThe value of πPhone stock has increased 8% each year for the past several years. In 2020,at was the stock worth in 2016? Equation: 7 years from now? In 2016?
Answer:
Part A
The worth of the stock in 7 years is approximately $145.68
Part B
The worth of the stock in 2016 is approximately $62.48
Part C
f(7) = 85 × (1 + 0.08)⁷
Part D
85 × (1 + 0.08)⁻⁴
Step-by-step explanation:
Question
"The value of the πPhone πhas increased 8% each year for the past several years. In 2020, the stock was worth $85. What will the stock be worth in 7 years? What was the stock worth in 2016? Equation: 7 years from now? in 2016?"
The equation for the growth of the stock to a final amount f(x) is given by the general equation for exponential growth as follows;
[tex]f(t) = a \cdot (1 + r)^t[/tex]
Where, in relation to the stocks;
f(t) = The value of the stocks after 't' years
a = The initial amount of the stocks
r = The rate of growth of the stock = 8%
t = The number of years of growth
Part A
The worth of the stock in 7 years, f(7), is found as follows;
The (initial) value of the stock in 2020, a = $85
The rate of increase in the value of the stock = The growth rate of the stock, r = 8% = 8/100 = 0.08
The number of years of growth, t = 7 years
We get;
f(7) = 85 × (1 + 0.08)⁷ ≈ 145.68
The worth of the stock in 7 years, f(7) ≈ $145.68
Part B
The value of the stock in 2016 is found as follows;
The number of years between 2020 and 2016 = 2016 - 2020 = -4 (years)
Here, let 'f(t)' represent the value of the stock in 2016, and therefore, we have;
t = -4 years
r = 8% = 0.08
a = The value of the stock in 2020 = $85
Plugging in the values gives;
f(-4) = 85·(1 + 0.08)⁻⁴ = 85 × (1.08)⁻⁴ ≈ 62.48
The value of the stock in 2016, f(-4) ≈ $62.48.
Part C
The equation for 7 years from now is f(7) = 85 × (1 + 0.08)⁷
Part D
The equation for 2016 is f(-4) = 85 × (1 + 0.08)⁻⁴.

In order, range, median, mode and mean. Round the mean to the nearest tenth.
PLS HELP ASAP
Answer:
Range: 40
Median: 55
Mode: 72
Mean: 54.6
Step-by-step explanation:
First, let's put all of the numbers down.
32, 34, 35, 40, 41, 54, 54, 56, 63, 69, 70, 72, 72, 72
Now, to find the range, subtract 72 - 32 = 40
To find the median, find the number in the middle
32, 34, 35, 40, 41, 54, 54, 56, 63, 69, 70, 72, 72, 72
Because there are an even amount of numbers we will find the mean of those two numbers which would be 55.
To find the mode, look for the number that appears the most.
32, 34, 35, 40, 41, 54, 54, 56, 63, 69, 70, 72, 72, 72
To find the mean, add everything up.
32, + 34, + 35, + 40, + 41, + 54, + 54, + 56, + 63, + 69, + 70, + 72, + 72, + 72 = 764
Then, divide. 764 ÷ 14 = 54.6 when rounded to the nearest tenth.
I hope that this helps, and you have a great day! :)
