segment DE is a midsegment of triangle ABC. find the value of x
Answer:
x = 10
Step-by-step explanation:
The value x is 10 units.
What is midsegment?A midsegment is the line segment connecting the midpoints of two sides of a triangle. Since a triangle has three sides, each triangle has three midsegments.
Given that, segment DE is a midsegment of triangle ABC.
According to the midpoint theorem, “The line segment in a triangle joining the midpoint of two sides of the triangle is said to be parallel to its third side and is also half of the length of the third side.”
Therefore, DE = 1/2 AB
5 = 1/2x
x = 5×2
x = 10
Hence, the value of x is 10 units.

A grid is 10 squares high and 10 squares wide. The distance between each grid square is 3 feet. The triangular viewing area of camera is shown. The right triangle has 2 sides with lengths of 5 grid squares. The area of the triangle is 112.5 feet squared.
Alan wants to install security cameras in his store, which has dimensions of 30 feet by 30 feet. Each camera can view an area of approximately 112.5 ft2, with a viewing area shaped like a right triangle.
How many cameras will be necessary to cover the entire store?
.
If he places cameras only in the corners of the store, how much area is left uncovered?
ft2.
Answer:
1) 8
2) 450 ft^2
Step-by-step explanation:
Each triangle takes half a square worth of space, so if you add up 2 triangles for 1 square that is 1/4 of the area, multiply that by 4 and you get 8 cameras.
The left over space in the store is the same amount of space as all the cameras space added together since each camera takes up half a square. That way 4 cameras(each 112.5 ft^2 each) equals 1/2 of the room which added together is 450 ft^2, the other half would be the left over space, 450 ft^2.
1) The cameras will be necessary to cover the entire store are 8
2) The area left uncovered is 450 ft^2
Each triangle takes half a square worth of space, so if you add up 2 triangles for 1 square that is 1/4 of the area, multiply that by 4 and you get 8 cameras.
What is the area of the triangle?
The area of the triangle is
[tex]=\frac{1}{2}\times height \times base[/tex]
The leftover space in the store is the same amount of space as all the camera's space added together since each camera takes up half a square.
That way 4 cameras(each 112.5 ft^2 each) equals 1/2 of the room which added together is 450 ft^2, the other half would be the leftover space, 450 ft^2.

Maribel will borrow $6250 at 13.5% APR. She chooses to pay it back in 2 years.
What will her monthly payment be? Use the table.
Use the rate table to figure out the monthly payments per one hundred dollars.
At a rate of 13.5% the interest per $100 is $ 4.778 per month.
Therefore, for two years the payment will be
$4.778 × 24 = $114.672 per $ 100
Therefore, the interest for a principal $6250 for two years;
(6250/100) × 114.672
= $7167
The monthly payment would therefore be
7167/24
= $298.625

Given that Sophia bought 3 bags of candy, and each bag has 15 pieces:
[tex]3*15 = 45[/tex]
Sophia has 45 total pieces of candy.
If Sophia would like to fill 9 party bags with the candy she has bought, she must divide the 45 total pieces of candy into the 9 party bags:
[tex]45[/tex] ÷ [tex]9=5[/tex]
Therefore, each party bag will have 5 pieces of candy in it.
Answer:
A. 5
Step-by-step explanation:
A, since you can follow these steps:
First, find how many total pieces of candy must be distributed. This is always what needs to be answered in this sort of question.
In this case, it is 3 bags of candy ⋅ 15 pieces of candy in each.
The result - from 3(15) - is 45 total pieces of candy.
Now, we see that we're distributing that value among 9 people (this is another correct way of wording it).
So the result is 45/9, which then results in 5 pieces of candy for 9 guests.

a) Write a system of equations that could be used to find the number of each coin he has.
Answer:
See belowStep-by-step explanation:
Let the number of nickels is n, number of quarters is q.
We know that:
Nickel = 5¢, quarter = 25¢, $2 = 200¢As per given we can set the following system:
n + q = 125n + 25q = 200Solving this we get:

Step-by-step explanation:
Mark the two points (-1,7) and (1,-1) on the graph. Then draw a straight line between them. To determine the equation that goes through these two points, we can use the two given points to find the slope of the line. The standard form of a straight line equation is
y = mx + b,
where m is the slope and y is the y-intercept (the value of y when x = 0).
Slope is also known as the "Rise"/"Run" - the change in y divided by the change in x. We can use the two points to calculate this:
Rise (-1-(7) = -8 Run = (1 - (-1) = 2
The slope is therefore (-8/2) or -4.
y = -4x + b
We can find b by entering either of the two points in y = -4x + b and solve for b. I'll use (1,-1) since I have my 1's multiplication table memorized
y = -4x + b
-1 = -4(1) + b
b = 3
The straight line equation that connects the two points is
y = -4x + 3
You can graph this equation (e.g., on DESMOS) to see how it intersects the points. [Attached]
The coordinates of the y intercept are (0,3).
The coordinate of the y-intercept of the line is (0, 3)
Equation of a line
The equation of a line in slope-intercept form is expressed as y = mx + b.
where:
m is the slope the lineb is the y-interceptGiven the coordinate points (-1, 7) and (1, -1).
Get the slope
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{-1-7}{1-(-1)}\\ m=\frac{-8}{1+1}\\ m=\frac{-8}{2}\\ m=-4[/tex]
Get the y-intercept:
Recall that y = mx + b
Using the coordinate point (1, -1) and m = -4
-1 = -4(1) + b
-1 = -4 + b
b = -1 + 4
b = 3
The equation of the line is y = -4x + 3
Get the y-intercept:The y-intercept occurs at the point where x = 0
y = -4(0) + 3
y = 0 + 3
y = 3
Hence the coordinate of the y-intercept of the line is (0, 3)

1 km = 1000 m
1 hr = 3600 sec. To convert km/hr into m/sec,
We multiply the speed which in this case is 22m/s
by 3.6 giving 79.2 kmh. Therefore 22m/s into kilometer is 79.2 kmh.

Answer:
797600km, 9172400 km, 2293100 km
Step-by-step explanation:
a. to find the amount of canada covered in fresh water, multiply 9970000 by 0.08 to get 797600km
b. the amount not covered by fresh water is 9970000-797600 which equals 9172400 km
c. multiply area of canada by 0.23 which is 2293100 km
just in case you might want to double check the zeros to make sure i did it right
Answer:
a. 797,600 km²
b. 9,172,400 km²
c. 2,293,100 km²
Step-by-step explanation:
To find a percent of a number, multiply the percent by the number. First, change the percent into a decimal number by moving the decimal point of the percent 2 places to the left. For example, 42% = 0.42; 7% = 0.07
Part a.
8% of 9,970,000 km²
Step 1. Multiply the percent by the number
8% of 9,970,000 km² = 8% × 9,970,000 km²
Step 2. Change the percent into a decimal number by moving the decimal point of the percent 2 places left.
8% of 9,970,000 km² = 8% × 9,970,000 km² = 0.08 × 9,970,000 km²
Step 3. Use a calculator or long division to do the multiplication.
0.08 × 9,970,000 km² = 797,600 km²
Answer: a. area covered in fresh water is 797,600 km²
Part b.
Subtract the area of part a. from the total area of Canada.
9,970,000 km² - 797,600 km² = 9,172,400 km²
Answer: b. area not covered in fresh water is 9,172,400 km²
Part c.
Tundra is 23% of total area.
23% of 9,970,000 km²
Step 1. Multiply the percent by the number
23% of 9,970,000 km² = 23% × 9,970,000 km²
Step 2. Change the percent into a decimal number by moving the decimal point of the percent 2 places left.
23% of 9,970,000 km² = 23% × 9,970,000 km² = 0.23 × 9,970,000 km²
Step 3. Use a calculator or long division to do the multiplication.
0.23 × 9,970,000 km² = 2,293,100 km²
Answer: a. area covered in tundra is 2,293,100 km²

Jimmy is interested in purchasing some yellow and red flowers for his mother's birthday. He visits a local floral shop and gift shop. Both businesses have a variety of flowers from which he can choose. Which answer best describes the sample and population
Answer:
ll available yellow and red flowers at the two businesses
Population: all available flowers at the two businesses
Step-by-step explanation:
The sample and population should be sample represents all yellow and red flowers while the population represents all flowers.
What are the sample and population?The entire group about whom you want to make conclusions is referred to as a population. The particular group from which you will gather data is known as a sample. The sample size is always smaller than the population as a whole. A population in research doesn't usually refer to humans.
An entire group from which a conclusion should be derived is referred to as a population. The sample, on the other hand, refers to the population from which the data is drawn.
So based on this, we can say that the sample represents all yellow and red flowers while the population represents all flowers.
