Answer:
8.75 feet
Step-by-step explanation:
Use the area formula, A = lw, where l is the length and w is the width
Plug in the area and length, and solve for w:
A = lw
140 = 16w
8.75 = w
So, the width is 8.75 feet
Answer:
8.75 ft
Step-by-step explanation:
Use the area formula, A = lw, where l is the length and w is the width
Plug in the area and length, and solve for w:
A = lw
140 = 16w
8.75 = w
So, the width is 8.75 feet

which inequality matches the graph?
Answer:
The inequality -3x + 2y ≥ 7 matches the graph ⇒ D
Step-by-step explanation:
The slope of the line whose equation is ax + by = c is m = [tex]\frac{-a}{b}[/tex]
From the given graph
∵ The direction of the line is increased from left to right
∴ The slope of the line is positive
∵ The line is solid and the shaded area is over the line
∴ The sign of inequality should be ≥
→ We have only one answer that has a sign of inequality ≥, let us check
its slope
∵ -3x + 2y ≥ 7
∴ a = -3 and b = 2
∵ m = [tex]\frac{-a}{b}[/tex]
∴ m = [tex]\frac{-(-3)}{2}[/tex] = [tex]\frac{3}{2}[/tex]
∴ The slope of the line is positive
∴ The inequality -3x + 2y ≥ 7 matches the graph

Step-by-step explanation:
In the table, look at the x values. Now, in the function ( the expression in the question) substitute the x values from the table into the function. The first column would be 4x1-1sqaured so 4 x 1 = 4 1 squared is 1 so 4 - 1 is 3. So the answer for the first box is 3.
1.Let x, y be any two numbers that satisfies the conditions x ≠0, y ≠0, and x 1
xy 0

Step-by-step explanation:
The water level in a reservoir is now 52 meters. If this was a 23% increase, what was the initial depth?
Answer:
40.04
Step-by-step explanation:
It was at 40.04 before the 23% increase. To find 23 % of 52 set it up as a inequality.
x/52 = 23/100
Cross multiply
52 * 23 = 1,196 100 * x =100x
Now solve for x.
100x /100 = 1,196/100 x = 11.96
Subtract answer from 52 to get answer
52 - 11.96 = 40.04

PLEASE HELP, WILL MARK BRAINLIEST !!!
Answer:
- 2
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 4, 3 ] , then
f(b) = f(3) = 3² - 3 - 8 = 9 - 3 - 8 = - 2
f(a) = f(- 4) = (- 4)² - (- 4) - 8 = 16 + 4 - 8 = 12 , tus
average rate of change = [tex]\frac{-2-12}{3-(-4)}[/tex] = [tex]\frac{-14}{7}[/tex] = - 2
A triangle has angle of 30 degree, 60 degree, 90 degree. It is dilated by a scale of 3. Give the angle measures of the dilation of the triangle.
Please help me with this question and explain your answer too...
Answer:
No matter what scale factor is dilated, the angles will not change.
My explanation:
A 30-60-90 right triangle (literally pronounced "thirty sixty ninety") is a special type of right triangle where the three angles measure 30 degrees, 60 degrees, and 90 degrees. The triangle is significant because the sides exist in an easy-to-remember ratio: 1:√3:2.
That is to say, the hypotenuse is twice as long as the shorter leg, and the longer leg is the square root of 3 times the shorter leg. You might also remember it as "X, 2X, and X roots of 3", which is how I remember it, but then you have to remember that 2X is actually the longest side, not X roots of 3.
Which side is which? The side opposite the 30 degree angle will have the shortest length. The side opposite the 60 degree angle will be √3
times as long, and the side opposite the 90 degree angle will be twice as long. The triangle below diagrams this relationship. Remember that the longest side will be opposite the largest angle, and the shortest opposite the smallest angle.
Hopefully this helped, if not HMU and I will try to get you a better answer! :)
find the e correctly
if u get a correct answer u will get brainliest!
Please help me please thank you sm in advance
Answer:
Your answer is 50 (or b)
Step-by-step explanation:
You can tell this because the inside angle is 25 but the cornner says 2x so you have to double it so 25+25=50...hope this helps
:P
Answer:
50
Step-by-step explanation:
There is a straight line at the bottom which is 180 degrees. On the right side the angle measure is 150 degrees so you subtract that by 180 and you get 30 degrees making it supplementary. Next you should know that there is 180 degrees in a triangle. Now you formulate the equation 30+50+2x =180. Then you solve for x and you get the solution x=50 which is your answer. Now you can substitute 50 in for x and see if all the angle measures add up to 180 degrees.
If you can please make my answer the brainliest that would be much appreciated. Thanks!

Lisa and Molly are on a bridge and see a tree sticking out of the water. Use the diagram to determine how far away Lisa is from the tree in the water. Use appropriate units.
Answer:
Distance between Lisa and the tree in the water = 26.5 ft
Step-by-step explanation:
From the figure attached,
Lisa is a point L, Molly is at M and a tree stick at point S.
By applying sine rule in ΔLMS,
[tex]\frac{\text{SinL}}{\text{SM}}=\frac{\text{SinM}}{LS}=\frac{\text{SinS}}{\text{LM}}[/tex]
[tex]\frac{\text{Sin(54)}}{22}=\frac{\text{Sin(103)}}{\text{LS}}[/tex]
LS = [tex]\frac{22\times \text{Sin}(103)}{\text{Sin(54)}}[/tex]
LS = 26.5 ft
Therefore, distance between Lisa and the tree in the water is 26.5 ft.

Maya estimates that the wait time for her favorite roller coaster is 35 minutes. The actual wait time is 55 minutes. What is the percent error of laya's estimate
Answer:
36.4%
Step-by-step explanation:
Actual wait time is 55 minutes
Approximate wait time is 35 minutes
Therefore the percent error can be calculated as follows
= 35-55/55 × 100
= 20/55 × 100
= 0.3636 × 100
= 36.4%
what is the surface area of the triangular prism represented by the net below?
9514 1404 393
Answer:
608 cm²
Step-by-step explanation:
The central rectangle is 10+12+10 = 32 cm high and 16 cm wide. Its area is ...
A = LW = (32 cm)(16 cm) = 512 cm²
Each of the two triangles on the side have an area of ...
A = 1/2bh = (1/2)(12 cm)(8 cm) = 48 cm²
There are two triangles and one rectangle, so the total surface area is ...
total area = rectangle area + 2 · triangle area
total area = 512 cm² +2(48 cm²) = 608 cm²
