Answer: y=54

Step-by-step explanation: since a triangles angles =180 and you just have this equation 180-72=2y that equals 108=2y

Answer:

The answer is B. 54 degrees.

Step-by-step explanation:

A triangle must be 180 degrees when all three angles are added together. 180 minus 72 is 108 degrees, which you have to divide by two, because there are two y values.

You can check this by adding 72 plus 54 plus 54 to get 180 degrees total.

Answer:

x = 10

Step-by-step explanation:

We see and show that  x = 10

This makes y = 5 and z = 7 as 5-7 (y-z) = -2

As y5-z7 = -2 then we add 10 = 8

x+y-z = 10x-2yz = 8

x-y+z =  10 -5  +7 = 12  we know  x = 10

We cna now prove.

x+y-z =8

x+5y-7z = 8

x +-2yz = 8

x = 8+2yz

x= 10

And prove

(x-5y)+7z= 12

x-y =12-7z

x = 5+5y

x=10

as x-5 (=5+7z) = 12

Have got the right answer here. Hope it helps.

Answer:

ok here you go

Step-by-step explanation:

i cant really plot them for you but i will help explain how to plot them.

the x-axis is the horizontal plane on the graph. the y-axis is the vertical plane on the graph. every coordinate has both a x and y point.

for you the x would be -8 and the y would be 7. first, you would go accross the x-axis to -8 and then go up to positive seven. you would be in the fourth quadrent in the graph. then  you would do the same to the other pair. remember, (x,y)

Answer:

28 feet long together

Step-by-step explanation:

in 1 yard there is 3 feet so in 4 yards it would be 3(4) which is 12. add 12 to 16 and you get 28

Answer:

28 feet

Step-by-step explanation:

A yard is 3 feet, so

4 yards*3 feet=12 feet.

12 feet+16 feet=28 feet

Answer:

D)The slope is -2/3

Step-by-step explanation:

First, put this equation in slope-intercept form by subtracting 2x on both sides:

2x+3y=6

-2x. -2x

Your equation should be:3y=-2x+6

Then, divide the whole equation by 3 since y has to be by itself

3y=-2x+6

---- ------

3. 3

Your equation should be y=-2/3x+6

Since the slope in slope-intercept form is m in y=mx+b, -2/3×=m

Final answer:D) The slope is -2/3

Answer:

Option (3). $1500

Step-by-step explanation:

Cost price of the jukebox = $9400

Down payment made by the diner = $1000

Diner agreed to pay the rest amount by $275 per month for 36 months

Total amount to be paid by the diner = Down payment + monthly payments

                                                              = 1000 + 275×36

                                                              = 1000 + 9900

                                                              = $10900

Finance charge = 10900 - 9400

                          = $1500

Therefore, option (3). 1500 will be the answer.

Answer:

-5

Step-by-step explanation:

5*-5=-25

5*1=5

A negative plus positive decreases in value

so -25+5=-20

Answer:

1023

Step-by-step explanation:

[tex]8^{0}[/tex] = 1, [tex]8^{\frac{1}{3} }[/tex] = [tex]\sqrt[3]{8}[/tex] = 2, [tex]8^{\frac{2}{3} }[/tex] = [tex]\sqrt[3]{8^2}[/tex] = 4, [tex]8^{1}[/tex] = 8

The series can be expressed in non exponent terms as

1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 + 512 ← 10 terms

There is a common ratio r between consecutive terms, that is

r = 2 ÷ 1 = 4 ÷ 2 = 8 ÷ 4 = .... = 2

This indicates the sequence is geometric with sum to n terms

[tex]S_{n}[/tex] = [tex]\frac{a(r^{n}-1) }{r-1}[/tex]

where a is the first term and r the common ratio

Here a = 1 and r = 2, thus

[tex]S_{10}[/tex] = [tex]\frac{1(2^{10}-1) }{2-1}[/tex] = 1024 - 1 = 1023

Answer:

Lauren made her first error in step 3 because she should have used 85 minus 60 = 25 for chemistry and 80 minus 60 = 20 for biology.  

Step-by-step explanation:

Lauren's box plots may have looked like those below.

Step 1

Chemistry median = 80

Biology median      = 70

Correct.

Step 2

Difference in medians = 80 - 70

Correct

Step 3

Chemistry IQR = 85 - 60 = 25

Biology IQR     = 80 - 60 = 20

Wrong.

This is where Lauren made the mistake.

She was finding the difference between the Max and Q3.

Answer: The volume of a sphere with a radius of 5 cm is approximately 523.33 cm3.

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a sphere (V) = 4/3 π radius³

Replacing with the values given and solving for V (volume)

V = 4/3 (3.14) 5³ = 4/3 (3.14) 125= 523.33 cubic centimeters

The volume of a sphere with a radius of 5 cm is approximately 523.33 cm3.

Answer:

B = 62.9ft

Step-by-step explanation:

The distance where she is from the oak tree is 75ft,

The angle of elevation the stone makes with the top of the oak tree is 40°

The height of the tree is x ft

See attached document for better illustration

Using SOHCAHTOA,

Tanθ = opposite/ adjacent

θ = 40°

Opposite = x ft

Adjacent = 75ft

Tan40 = x / 75

X = 75 × tan40

X = 75 × 0.8390

X = 62.92ft

The height of the oak tree is 62.9ft

Answer:

9 months.

Step-by-step explanation:

Well we subtract the one time fee of $150 from $420

420-150=270

Now we need to divide $270 by $30, the price she pays every month.

270÷30=9

She has had the service for 9 months.
