Answer:
34.44
Step-by-step explanation:
The distance formula can help you find the lengths of the diagonal sides.
d = √((x2 -x1)^2 +(y2 -y1)^2)
DO = √((6 -0)^2 +(0 -7)^2) = √(36 +49) = √85
OG = √((3 -6)^2 +(-4 -0)^2) = √(9 +16) = 5
The length of NG is 3 -(-3) = 6.
The perimeter is the sum of the side lengths:
P = DI +IN +NG +GO +OD = √85 +5 +6 +5 +√85 = 16 +2√85
P ≈ 34.43909 ≈ 34.44 . . . units

Terry makes $2400 per month in gross income. His net earnings are 80% of his gross. His utility bills total $150. What percentage of Terry's net earnings is he spending on utilities?
Answer:
7.81%
Step-by-step explanation:
First, you have to calculate the net earnings by calculating the 80% of the gross income:
gross income= $2,400
net earnings= $2,400*80%= $1,920
Then, you have to calculate the percentage that represents the utility bills spending from the net earnings by dividing $150 by the net earnings and multiplying for 100:
($150/$1,920)*100= 7.81%
According to this, the answer is that 7.81% of Terry's net earnings are spent on utilities.

Midpoint = (2,5)
A = (x₁,y₁) = (1,7)
M(x,y) = [tex](\frac{x1+x2}{2} , \frac{y1+y2}{2})[/tex]

3. Stan is deciding between patio tiles that are 39 cm by 39 cm and tiles that are 18 cm
by 27 cm. His patio is 3 m by 2.5 m. Considering area only, how many of each type
of tile would he need?
Answer:
Stan needs about 50 of the 39 cm x 39 cm tiles
or about 155 of the 18 cm x 27 cm tiles
Step-by-step explanation:
Since we are asked to consider only matters of area, we need to calculate first, the area of the patio:
Patio area = 3 m x 2.5 m = 7.5 m^2
Now we consider what surface (in square meters - m^2) each type of tiles cover:
a) for the 39 cm x 39 cm tiles: 0.39 m x 0.39 m = 0.1521 m^2
b) for the 18 cm x 27 cm tiles: 0.18 m x 0.27 m = 0.0486 m^2
Therefore, to cover the area of the patio, the number of tiles type "a" needed is given by the quotient:
7.5 m^2 / 0.1521 m^2 = 49.3096 (about 50 tiles)
while for type "b" tiles the quotient gives:
7.5 m^2 / 0.0486 m^2 = 154.32 (about 155 tiles)
It takes Virginia 9 minutes to ride her skateboard 3 blocks.
Using this unit rate, how many minutes will it take Virginia to ride her skateboard 1 block?
Answer:
3 minutes
Step-by-step explanation:
We can use ratios to solve
3 blocks 1 block
----------------- = --------------
9 minutes x minutes
Using cross products
3 * x = 9*1
3x = 9
Divide each side by 3
3x/3 = 9/3
x = 3
So the right answer is 3.

Liner equation Melissa and Jane are planting trees Melissa plants 10 tree in 1 hour Jane plants 17 trees in 2 hours enter an equation that can be used to find the number of hours t t takes Melissa and Jane to plant 111 trees together
Answer:
6 hours
Step-by-step explanation:
What we must do is calculate the speed of each one,
Melissa in one hour plants 10 trees, that is 10/1 is her speed.
Jane in two hours plants 17 trees, that is 17/2 is her speed.
Now, we want to know the time it takes to plant 11 trees, so the sum of the previous speeds is equal to 111 / x
10/1 + 17/2 = 111 / x
18.5 = 111 / x
x = 111 / 18.5
x = 6
Which means that in 6 hours between the two they can plant 111 trees

What is the length of the hypotense,c?

36 m
Answer:
Choice C
Step-by-step explanation:
Using the Pythagorean theorem, you can find that the length of the hypotenuse is:
[tex]\sqrt{3^2+5^2}=\\\\\sqrt{9+25}=\\\\\boxed{\sqrt{34}}[/tex]
Hope this helps!
Answer:
[tex]c=\sqrt{34}[/tex]
Step-by-step explanation:
Using the Pythagorean theorem (a^2 + b^2 = c^2), you can find the hypotenuse
Begin by plugging in 3 into a and 5 into b.
3^2 + 5^2 = c^2
9 + 25 = c^2
34 = c^2
Then, take the square root of both sides.
[tex]\sqrt{34} =\sqrt{c^{2} }[/tex]
[tex]c=\sqrt{34}[/tex]
The present age of Joyal’s mother is three times the present age of joyal. After 5 years their ages will add up to 66. Find their present age
Answer:
The present age of Joyal is 14 years.
The present age of Joyal's mother is 42 years
Step-by-step explanation:
Let J denotes the age of Joyal
Let M denotes the age of Joyal's mother
The present age of Joyal’s mother is three times the present age of joyal.
Mathematically,
M = 3J
After 5 years their ages will add up to 66
Mathematically,
(M + 5) + (3J + 5) = 66
M + J + 10 = 66
M + J = 66 - 10
M + J = 56
But we know that M = 3J
3J + J = 56
4J = 56
J = 56/4
J = 14 years
So the present age of Joyal is 14 years.
M = 3J
M = 3(14)
M = 42 years
So the present age of Joyal's mother is 42 years.

Answer:
economy class = 260
business class = 100.
Step-by-step explanation:
for every 13 economy seats, there are 5 business class seats
EC = 13
BC = 5
ADD to get total = 18
divide 360 by 18 to get the number of groups created.
you get 20.
multiply 20 by each class seats
13 by 20 = 260
5 by 20 = 100
you can confirm by adding the seats to see if you will get 360.

Joey is building a frame for a sandbox. The sandbox is going to be a quadrilateral that has the lengths shown. A rectangle is shown. The length of the top and bottom sides are 8 feet, and the length of the left and right sides are 12 feet. A diagonal that is 14 feet long is drawn from the bottom one corner of the rectangle to the other corner of the rectangle. Points X and C are opposite to the diagonal. If the diagonal of the sandbox measures 14 feet, which best describes the shape of the sandbox? a rectangle, because angle C is a right angle a rectangle, because angle C and angle X are congruent a quadrilateral, because angle C and angle X are acute a quadrilateral, because angle C and angle X are obtuse
Answer:
C) a quadrilateral, because angle C and angle X are acute
Step-by-step explanation:
It is a quadrilateral because angle C and angle X are acute angles and not right angles option third is correct.
What is quadrilateral?It is defined as the four-sided polygon in geometry having four edges and four corners. It has two pairs of congruent sides and one pair of opposite congruent angles.
From the Pythagoras theorem:
[tex]14^2=12^2+8^2[/tex]
196 ≠ 208
The angles C and X are not right angles since angles C and X are congruent and acute angles.
Thus, it is a quadrilateral because angle C and angle X are acute angles and not right angles option third is correct.

for the Black Panther trip 420 students were scheduled to go. After selecting more parents surveys 15% more students are going on the trip each Administration ticket cost 22.75 dollars what was the total amount pay for all the tickets purchased
Answer: $10988.25
Step-by-step explanation:
From the question, we are told that for the Black Panther trip 420 students were scheduled to go and 15% more students were selected. This means that the total number of students that are going will be:
= 420 + (15% × 420)
= 420 + (0.15 × 420)
= 420 + 63
= 483 students
Since each administration ticket cost 22.75 dollars. The total amount paid for all tickets purchased will be:
= 483 × $22.75
= $10988.25

The Air conditioner unit in the classroom uses 120 volts. it requires 2000 watts of usage on the average, and it stays on for 8 hours every day. Find out the Amps, Watt hrs/Day, Watts hrs/yr, Kilowatt Hrs/Yr and cost/Yr if the cost of elelctricity per kilowatt is $0.25
Step-by-step explanation:
P = IV
2000 W = I (120 V)
I = 16.7 A
P = E/t
P = (2000 W × 8 hr) / (1 day)
P = 16,000 W·hr/day
P = 16000 W·hr/day × (365 day / yr)
P = 5,840,000 W·hr/yr
P = 5,840,000 W·hr/yr × (1 kW / 1000 W)
