Step-by-step explanation:
A point is reflected across the x-axis. The new point is (5,-3.5). What is the distance between the two points?
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

An athlete takes 10 rounds of a rectangular park, 60 m long and 35 m wide. Find the total distance covered by him
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

PLEASE HELP ME ASAP
Answer:
Look below
Step-by-step explanation:
(a)
The Pythagorean Theorem is a^2+b^2=c^2. In this case. a=10, b=y, and c=2+y.
So, [tex](2+y)^{2}=10^{2}+y^{2}[/tex].
(b)
Using the equation (2+y)^2=10^2+y^2, solve for y.
(2+y)^2=10^2+y^2Square it, 4+4y+y^2=100+y^2Subtract y^2, 4+4y=100Subtract 4, 4y=96Divide by 4, [tex]y=24[/tex].Find the circumference of the pizza. Round your answer to the nearest tenth.

how of find the area of a composite figure
Step-by-step explanation:
A composite figure is made up of simple geometric shapes. To find the area of a composite figure or other irregular-shaped figures, divide it into simple, nonoverlapping figures. Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure. Formula = a(a=lw+bh)
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)?
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

A car uses 1 liter of gas every 12 kilometers. How many meters can the car travel on 3 liters of gas? 36 meters 3,600 meters 360 meters 36,000 meters
Answer:
36,000 meters. 12km= 12,000m multiply by 3l of gas.
Step-by-step explanation:
The car will travel 36000 meters using 3 liters of gas as per linear equation.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, 'A' is a coefficient and 'B' is constant".
Given, a car uses 1 liter of gas every 12 kilometers.
Therefore, using 3 liters of gas, the car will go
= 3 × 36 kilometers
= 36 kilometers
= 36000 meters
With 3 liters of gas, the car will travel 36000 meters.

pls help 209572.999129 round to the nearest cent
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.
