Answer:
500m
Step-by-step explanation:
a rectangle has 4 sides, so 30=60 and 20=40
60x5=300
40x5=200
300+200=500
500m
reason of 500
The main reason for this is he ran AROUND the rectangle and did it 5 TIMES, doing it once would be 100m.

length of one of the legs of the isosceles triangle.
Answer:
What do u mean by legs please can you explain it further
Help me please thanks
Given:
Triangle ABC and triangle DEF are similar triangles.
To find:
The proportion that can be used to find the length of segment DE.
Solution:
We know that the corresponding sides of similar triangles are proportional.
Triangle ABC and triangle DEF are similar triangles. So, their corresponding sides must be proportional.
[tex]\dfrac{AB}{DE}=\dfrac{BC}{EF}=\dfrac{AC}{DF}[/tex]
[tex]\dfrac{AB}{DE}=\dfrac{BC}{EF}[/tex]
[tex]\dfrac{4}{DE}=\dfrac{3}{9}[/tex]
[tex]\dfrac{4}{3}=\dfrac{DE}{9}[/tex]
Therefore, the correct option is A.
0.4 repeating as a fraction for a mixed number
Answer:
Step-by-step explanation:
1.Rewrite the decimal number as a fraction with 1 in the denominator
2.Multiply to remove 1 decimal places. Here, you multiply top and bottom by 101 = 10
3.Find the Greatest Common Factor (GCF) of 4 and 10, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,
so the answer is
0.4= 2/5

Find the area of quarter circle with the radius of 10
Answer: 78.5
Step-by-step explanation:
Formula: A=pi*r^2 or Area = 3.14*radius squared (by two)
A = 3.14*10^2
A = 3.14*100
A = 314
Divide it by 4, because it's a quarter of the circle: A = 314/4
A = 78.5
Answer: 78.5

What is the answer X/7-3>8
Answer:
x > 77
Step-by-step explanation:
According to order of operations rules, we must carry out division before addition or subtraction. In this case we wish to isolate x and are permitted to simplify the inequality by combining the "like terms" 3 and 8, as follows:
X/7-3>8
+3 +3
--------------
x/7 > 11
The easiest way in which to solve for x is to multiply both sides of this inequality by 7:
7(x/7) > 7(11), or
x > 77
All numbers greater than 77 are part of the solution set.

Paige started to make a rectangular prism using centimeter cubes, as shown below. When Paige completes the prism, the volume will be 60 cubic centimeters. What will be the height, in centimeters, of Paige's completed rectangular prism?
Answer:
The volume is 12.
Step-by-step explanation:
If you multiply l x w x h
4 x 3 x 1 = 12
l x w x h
Answer:
my guess is 5 cm
Step-by-step explanation:
im not really good at math but i think its 5 cm because 60 divided by 12 is 5
hope i helped some people :D
Two blocks of wood are shaped as a right rectangular prism the smaller block has a length of 9 cm a width of 3 cm and a height of 7 cm the dimensions of the larger block are double the dimensions of the smaller block what is the volume of the larger block of wood
Answer:
1512 cm^3
Step-by-step explanation:
the small ones dimentions are 9 by 3 by 7
if you double that then it is 18 by 6 by 14
to figure out the volume you have to multiply all the numbers together
and you get 1512 cm^3

To three decimal places, find the value of the first positive x-intercept for the function f(x) = -2cos(x + 1). (6 points)
0.571
1.571
-1.081
-2.571
PLEASE HELP URGENT I AM TAKING IT NOW
I'm not 100% sure about this because this unit confused me but...
if you put it in your graphing calculator or in desmos, you can see that the first positive x -intercept (which is a point that is on the x-axis) is somewhere around one but it's not 1.571!! (other person is wrong!)
that point is (0.571, 0) so it's the first option
Eric was rock climbing. At one point, he stopped and climbed straight down 2 1/2 meters. Then he climbed straight up 6 3/4 meters. Eric was wondering what his change in elevation was after these two moves.Which of the following equations matches the situation above?
Choice a: 2 1/2-6 3/4=?
Choice b: -2 1/2+6 3/4=?
Choice c: none of the above
NEED NOW
Answer:
Choice b
Step-by-step explanation:
He starts by going down, so that is descending, and would be a negative number. Then he is climbing, so that’s a positive number.

Make A the subject of the formula r=√А/3
Answer:a = 9 r^2
Step-by-step explanation:
We need to make a subject of the formula given r = square root a / 3
Given r = √a / 3 -------------1
Now we can find a.
Squaring the given equation 1 we get
So r^2 = (√a / 3)^2
So r^2 = a / 9

HELP PLEASE! WILL NE MUCH APPRECIATED❤
A circular flower bed is 23 m in diameter and has a circular sidewalk around it that is 4 m wide. Find the area of the sidewalk in square meters. Use 3.14 for π.
Answer: 244.92 m
Step-by-step explanation:
The area of a circle is pir^2. First you will need to find the area of the concrete and subtract the area of the flower bed from that amount. The concrete is 3 feet wide so you will add that to 11.5 (half of the flower bed diameter) to find the radius. 14.5^2 pi is the entirety of the area. Then subtract 11.5^2 pi for the area of the concrete.
HELP!!!!! Correct only!
Answer:811.5
Step-by-step explanation:
Answer:
Step-by-step explanation:
(7.5ftx9ftx12ft)+[5(9ftx12ft)+2(1/2x5x√(4.5^2+1.5^2)ft)]
=810ft+[540ft+2(1/2x5x6.75)ft]
=810ft+(540ft+33.75ft)
=1383.75ft
(sorry I'm not too sure if it is correct )
