Answers
Answer:
a. x = 22
b. Perimeter = 100
Step-by-step explanation:
a. Based on the proportionality theorem, we have the following:
(2x - 4)/8 = (36 - 6)/6
(2x - 4)/8 = 30/6
(2x - 4)/8 = 5
Cross multiply
2x - 4 = 8*5
2x - 4 = 40
2x = 40 + 4
2x = 44
x = 44/2
x = 22
b. Perimeter of ∆JKL = KJ + KL + JL
KJ = 2x - 4 + 8
Plug in the value of x
KJ = 2(22) - 4 + 8
KJ = 44 - 4 + 8 = 48
KL = 36
JL = 16
Perimeter = 48 + 36 + 16
Perimeter = 100

An athlete takes 10 rounds of a rectangular park, 60 m long and 35 m wide. Find the total distance covered by him
Answers
Answer:
1900M
Step-by-step explanation:
If the athlete runs round a rectangular park, the distance covered can be determined by calculating the perimeter of the park
Perimeter of a rectangle = 2 x (length + width)
2 x (60 + 35) = 190m
Since he run rounds 10 times, the total distance covered = 190m x 10 = 1900m

A point is reflected across the x-axis. The new point is (5,-3.5). What is the distance between the two points?
Answers
Answer:
Distance between the points = 7 units
Step-by-step explanation:
If a point P(h, k) is reflected across x-axis, rule to be followed will be,
P(h, k) → P'(h, -k)
By this rule,
If the coordinates of new point P' are (5, -3.5)
Then the coordinates of pre-image point P will be (5, 3.5)
By using formula to get the distance between two points,
Distance = [tex]\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
Distance between (5, 3.5) and (5, -3.5) = [tex]\sqrt{(5-5)^2+(3.5+3.5)^2}[/tex]
= [tex]\sqrt{0+7^2}[/tex]
= 7 units

pls help 209572.999129 round to the nearest cent
Answers
Answer:
$209,573.00
Step-by-step explanation:
when rounding to a place, you only need to look at the numbers one place beyond the place you are rounding to. For example, if you want to round 0.878 to the nearest tenth, you only need to look at 0.87, since both 0.87 and 0.878 round to 0.9. In this case, you are rounding to the nearest hundredth because one cent represents one hundredth of a dollar. You only need to look at 209572.999. Since the last digit is 9, which is greater than 5, you round up to 209573.00.

What is the answer for, A metal bar 8.15 ounces 93% of the bar is sliver. How many ounces of silver are in the bar? ( round to the nearest thousandth)?
Answers
Answer:
7.580 ounces
Step-by-step explanation:
The question is asking how many ounces of silver are in the bar. We know that 93% of the bar is silver. The bar is 8.15 ounces. This means we need to find 93% of 8.15. Let's set up an equation.
93% of 8.15
93/100 • 8.15
0.93 • 8.15
= 7.5795
Round to the nearest thousandth.
7.580 ounces

What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
At schools art teacher designs a circular flower bed inside a rectangular sandbox.
Here, We have;
The sandbox is 6 feet wide and 10 feet long.
Now, We get;
⇒ Radius of circle = 5 feet
Hence, Area of circle = πr²
⇒ Area of circle = 3.14 × 5²
⇒ Area of circle = 78.5 cm²
And, Area of rectangular sandbox is,
⇒ 10 × 6
⇒ 60 feet²
Thus, There will be after the flower bed is installed = 78.5 - 60
= 18.5 feet²
