A pole that is 2.9 m tall casts a shadow that is 1.77 m long. At the same time, a nearby
tower casts a shadow that is 47.25 m long. How tall is the tower? Round your answer to the nearest meter.
Answer:
77 m
Step-by-step explanation:
The 2 situations are similar , so the ratios of corresponding sides are equal.
let h be the height of the tower, then
[tex]\frac{2.9}{h}[/tex] = [tex]\frac{1.77}{47.25}[/tex] ( cross- multiply )
1.77h = 137.025 ( divide both sides by 1.77 )
h ≈ 77 m ( to the nearest metre )

Find the volume of the cylinder
Either enter an exact answer in terms of t or use 3.14 for t
10
4 units
Answer:
502.4 cubic unit
Step-by-step explanation:
Given data
The parameter for the cylinder is as follows
Height h= 10units
Radius r= 4 units
We know that the expression for the volume of a cylinder is
V= πr^2h
substitute
V= 3.14*4^2*10
V= 3.14*16*10
V= 502.4 cubic unit
Hence the volume is 502.4 cubic unit

Graph a line that is perpendicular to the given line. Determine the slope of the given
line and the one you graphed in simplest form. Click and drag on the graph to draw a
line.
Answer:
y=2/3
Step-by-step explanation:
Find two points on the line and find the slope.
1,-3 -1,1
y1-y2/x1-x2
-3-1/1--1
-3/2
Then find the reciprocal of this slope by flipping the numerator and the denominator, changing the sign from positive to negative and visa versa.
A rectangle is placed around a semicircle as shown below. The length of the rectangle is 3 cm. Find the area if shaded region. Use the value 3.14 for pie, And do not round your answer.
Answer:
0.9675sq.cm
Step-by-step explanation:
Find a related diagram attached
Area of the shaded region = Area of rectangle - area of semicircle
Area of rectangle = 3cm * 1.5cm
Area of rectangle = 4.5sq.cm
Given
diameter of the semicircle = 3cm
area = πd²/8
Area of the semicircle = 3.14(3)²/8
Area of the semicircle = 3.5325sq.cm
Area of the shaded region = 4.5 - 3.5325
Area of the shaded region = 0.9675sq.cm
Josh is driving from his house to his grandmother's house. If 1/3 gallon of gasoline will get Josh 1/9 of the way to his grandmother's, how many gallons of gasoline does Josh need for the entire trip?
Answer:
3 Gallons
Step-by-step explanation:
Answer:
3 gallons
Step-by-step explanation:
Given: 1/3 gallon needed for 1/9 of the whole trip
To find: How many gallons of gasoline Josh needs for the entire trip
Solve: Firstly, we need to find out the entire trip as a fraction
1/1
If 1/9 = 1/3, then 1/1 = 1/9 ÷ 1/3 = 0.33
No, multiply that by 1/1
1/1 × 0.33 = 0.33
Then, convert 0.33 to a whole number
Hence, Josh needs 3 gallons for the entire trip
use the difference of two squares to find the value of 612 - 392
Answer: 4 (153 - 98)
formula is a^2-b^2=(a+b)(a-b)
factor out the GCF:
4(153−98)
both terms are not perfect squares so
you cant factor it further.
Use the equation below to find y, if m =6, x = 3, and b = 5.

What type of triangle is ABC?
Give reasons for your answer.
Answer:
I'll say that it is a scalene triangle because all of the sides of the triangle have different lengths.
Angle CAB is congruent to angle ACD because they are alternate interior angles (note the parallel lines AB and DE). So this makes angle CAB to be 50 degrees.
For similar reasoning, angle BCE = angle ABC = 80 degrees.
Focus on the angles that are centered at point C. Those three angles form a straight line so they add to 180 degrees.
(angle ACD) + (angle ACB) + (angle BCE) = 180
(50) + (angle ACB) + (80) = 180
(angle ACB) + 130 = 180
angle ACB = 180-130
angle ACB = 50 degrees
Ultimately, this leads to triangle ABC having the interior angles of A = 50, B = 80 and C = 50.
Because we have exactly two interior angles that are the same measure, this must mean triangle ABC is isosceles. The congruent angles are opposite the congruent sides, meaning that AB = BC.
Please help thank youu!

Tell me the answer please. Give me a short answer and a step-by-step explanation.
Answer:
( -4 , 16 )
Step-by-step explanation:
1/2x + 18 = 5/2x + 26
-8 = 4/2x
-4 = x
so the lines cross at -4 x so, then plug that number into either equation to see what y is
y = 1/2(-4) + 18
y = 16

You decide to get an estimate on the cost of repairs for the green food truck. The mechanic explains that the cost of the repairs comes out to be about $9,500. This price includes the cost of labor and the cost of the parts needed to do the repairs. If labor costs are 3/5 the cost of the parts, how much would you save by doing the repairs yourself and just purchasing the parts?
Answer:
you save labor : 3562.50
Step-by-step explanation:
You want to calculate for labor.
labor = 3/5 (parts)
labor + parts = $9500 (total costs)
3/5 parts + parts =9500
3/5 parts + 5/5 parts = 9500
8/5 parts=9500
5/8(8/5 parts) = 5/8 (9500)
‘parts = 5937.50
labor=3562.50 (3/5 x 5937.50)
total = 9500

The height h, in feet, that an arrow will reach 1 seconds after being shot directly upward is given by the formula h = 1121 - 1612
How high will the arrow be after 4 seconds?
Answer:
4484 - 6448
Step-by-step explanation:
Given: 1 second = 1121 - 1612.
To find: How high the arrow will be after 4 seconds.
Solution:
If 1 second = 1121 - 1612, then 4 seconds = 4 × 1
4 × 1121 - 1612 = 4484 - 6448
Therefore, the arrow will be as high as 4484 - 6448 in 4 seconds.

Answer:
II and III
Step-by-step explanation:
Causation always means coorelation, but corelation doesn't always mean causation.
Also, correlation is a two-sided relationship while causation is not. Hot days cause more ice cream sales but ice cream does not cause more hot days. However, hot days are correlated with ice cream and ice cream is correlated with hot days.
Therefore, only II and III are correct.
