This problem is just try and error.
First we try number 2.5 since its the average of all the answers.
2.5^2=6.25
This is smaller than 7 so the answer is either 2.6 or 2.8
Now let's try 2.7
2.7^2=7.29
Which is bigger than 7 and that means the correct answer is 2.6 :)
Omari buys a computer for $1,083. She
makes a down payment of 20%. She pays
$144.40 per month to finish paying for
the computer. How many months will it
take Omari to finish paying?
Answer:
6 months.
Step-by-step explanation:
To find the answer, we first need to find out how much Omari paid for the down payment. To find this, you multiply 1083*0.20 and you get $216.60. So we subtract the down payment from the total leaving us with $866.40. Now to find out how many months it would take Omari to pay, we divide 866.40/144.40 since each month she pays $144.40 a month. Once you divide 866.40/144.40, you are left with an answer of 6 months.
Phil is riding his bike. He rides 25 miles in 2 hours, 37.5 miles in 3 hours, and 50
miles in 4 hours. Find the constant of proportipnality and write an equation to
describe the situation. Let x represent the number of hours.
The equation that describes the relationship is y =
The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour.
The equation is
d
=
12.5
×
t
Explanation:
To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:
For example
25
miles
÷
2
hours
=
12.5
miles
hour
A direct proportionality will always result in an equation that resembles this:
y
=
k
x
where
y
and
x
are the related quantities and
k
is the constant of proportionality. If you draw a graph using the values you have, the graph will show a straight line the passes through the origin. The slope of this line will be the constant of proportionality. (And if the values given are real physical quantities, this constant will contain important information about the situation you are studying!)

Answer:
[tex]Area=\frac{ab}{2} \\\\area=\frac{9.5.23}{2} \\\\answer=108.8 yd^{2}[/tex]
Step-by-step explanation:
I hope this helps ^_^
The area of the triangle is 108.7 square yards.
What is the area of the triangle?Let a, b, and c is the sides of the triangle.
The area of the triangle is given as
S = (a + b + c) / 2
[tex]\rm A = \sqrt{s(s - a)(s - b)(s -c )}[/tex]
The third side of the triangle will be
c² = a² + b² - 2ab cos θ
c² = 9.5² + 23² - 2 × 9.5 × 23 × cos 85°
c² = 619.25 - 38.09
c² = 581.16
c = 24.11 yd
Then the area of the triangle will be
S = (9.5 + 23 + 24.11) / 2
S = 56.61 / 2
S = 28.3
Then the area will be
[tex]\rm A = \sqrt{28.3(28.3 - 24.11)(28.3 - 23)(28.3 - 9.5)}[/tex]
Simplify the expression, then the value will be
A = √11815.01
A = 108.7 square yd
The area of the triangle is 108.7 square yards.

Complete the statements about the cone.
The height is units.
The radius is units.
The volume is Tot cubic units.
10
6
Answer:
The answers are:
The height is 6
The radius is 8
The volume is 128 π cubic units.
Step-by-step explanation:
The height is shown in the picture. So the first answer is 6.
To find the radius, you use the equation. [tex]\sqrt{slant height^{2}- height^{2} }[/tex] = radius
The slant height 10, and the height is 6. So you plug those into the equation and solve.
[tex]\sqrt{10^{2}-6^{2} }[/tex] =
[tex]\sqrt{100-36}[/tex] =
[tex]\sqrt{64}[/tex] = 8
So the radius is 8.
Now we use the equation [tex]\pi[/tex][tex]r^{2}[/tex] [tex]\frac{h}{3}[/tex] = volume.
[tex]\pi[/tex][tex]8^{2}[/tex] [tex]\frac{6}{3}[/tex] =
[tex]\pi[/tex]64 [tex]\frac{6}{3}[/tex] =
[tex]\pi[/tex] 64(2) = 128 [tex]\pi[/tex] cubic units
I hoped this helped you. I would love brainiest.
The statements about the cone is that,
The height is 6 units, the radius is 8 units and the volume is 128π cubic units.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given a cone.
We have to find the complete the statements related to the cone.
From the figure,
height of the cone = 6 units
Using the Pythagoras theorem,
Radius of the cone = √(10² - 6²) = 8 units
Volume of the cone = 1/3 π r² h
= 1/3 π × 8² × 6
= 128π cubic units
Hence the height, radius and volume of the cone are 6 units, 8 units and 128π cubic units respectively.

Answer:
y=-1.7x+8
Step-by-step explanation:
An equation of a line is y=mx+c
m is the gradient and c is the y intercept, which is where the line intercepts y.
you work out m getting two points and then subtracting y - y ÷ x - x
So in this graph, if we chose points (6,-2) and (3,3) then we would do this equation.
[tex] \frac{3 - - 2}{3 - 6} = \frac{5}{ - 3} = - 1.7[/tex]
So m = -1.7
c = 8 because it goes through 8 in y.
So the equation is y=-1.7x+8

Write an equation of a line through the point (-4,-1) that is parallel to the line y= -3/4x + 4
Answer:
y = -3/4x -4
Step-by-step explanation:
Parallel slope = -3/4
(-4,-1)
y - y1 = m(x - x1)
y + 1 = -3/4(x + 4)
y + 1 = -3/4x - 3
y = -3/4x -4

Just trying to win the CONTEST BUT GOOOOD LUCK
Answer:
56 units, 84 units, 56 units, 140 units
Step-by-step explanation:
Since you have the ratios, you can multiply each by x, because you do not know the actual values.
2x+3x+2x+5x=336
12x=336
÷12 ÷12
x=28
