A =surface area 528cm

Answer:

the last one is the answer I thin

Answer:

D

Step-by-step explanation:

Hey There!

Remember in order for the relation to be a function none of the x values can repeat

For the first one the x value 0 repeats therefore it is not a function

for the second one the x value -7 repeats thus meaning that its not a function

for the third one the x value 6 repeats hence, it is not a function

for the last one each input has a different output therefore it is a function

Answer:

False

Step-by-step explanation:

Based on what is stated in the question :

Expressing the worded equation Mathematically,

(5x - 7) / 2 = y

If y = 28

(5x - 7) / 2 = 28

Cross multiply

5x - 7 = 28 * 2

5x - 7 = 56

5x = 56 + 7

5x = 63

x = 63 / 5

x = 12.6

Hence, x ≠ 9

Complete question :

Laura and Martin obtain a 30-year, $180,000 conventional mortgage at 10.0% on a house selling for $210,000. Their monthly mortgage payment, including principal and interest, is $1566.00. Determine the total amount they will pay for their house. How much of the cost will be interest? How much of the first payment on the mortgage is applied to the principal?

Answer:

$563760 ; $383760 ; $66

Step-by-step explanation:

Given that:

Monthly mortgage payment = $1566

Period = 30 years

Number of months in period = (30 * 12) = 360

Principal = $180,000

1.)

Total amount paid :

Monthly payment * period

$1566 * 360 = $563760

2.)

Total amount paid = Principal + Interest

Interest = Total amount paid - principal

Interest = $563760 - $180000

Interest = $383760

3)

First payment = 1566

Interest rate = 10% per annum = 0.1 / 12 = 0.0083333

monthly interest: 180,000 * 0.0083333 = 1500

Principal = 1566 - 1500 = $66

Answer:

y=5.4

Step-by-step explanation:

So first we cross multiple.

2*112=35*(y+1)

224=35y+35

-35 on both sides

189=35y

÷35 on both sides

5.4=y

Answer:

De acuerdo a la información proporcionada, dado que se van a repartir 5 barritas entre 8 niños, se tiene que dividir las barritas entre el número de niños y a partir de aquí, se construye la fracción 5/8. Esto lo que indica es que cada barrita se divide en ocho pedazos y cada niño recibiría 1/8 de cada barrita y para las 5 barritas sería:

1/8*5=5/8

Answer:

x=28

Step-by-step explanation:

I am assuming the mean is arithmetic mean. So we first add up the numbers:

6+10+12+18+16+x

=22+10+30+x

=22+40+x

=62+x

Then since there's 6 numbers in total, we have an equation:

[tex]\frac{62+x}{6}=15\\62+x=90\\x=28[/tex]

The answer is 28!

Have a nice day! :)

Answer:

Thanks for asking for the explanation, everyone wants just the answer, You want to know how to solve the problem , great.  :)

Step-by-step explanation:

Our strategy  and one you can use on any triangle problem.  

the interior angles add to 180° .  Remembering that, seems to me, that very often is the "key" to figuring out triangle problems.

keeping that in mind, we know to add up all the inside angles to 180

180= A + B + C

from this particular triangle then,  we have

A = 6X

B = 90   ( b/c that's what the small red square is telling us, it's a 90 angle )

C = 5x - 2

put that all together

180 = 6x + 90 +5x - 2

now use your algebra skills to solve for X ( and to be fair, this is where lots of people struggle, the algebra skills are not so good )

so I'll just go slow

put like terms together

180 = 11x + 88  ( I just added the terms with an x,  and the constant terms )

move the 88 over to the other side by subtracting

92 = 11x

divide both sides by 11

92 / 11 = x

8.3636 = x

now that we know x, plug it into the expression for the angle next to the y angle in the picture

5x - 2

5(8.3636) - 2

39.8181

then y is the other part of another 180 pair of angles sooo use that again

180 = 39.8181 + y

solve for y

140.1818 = y

Hope this helps, ask any questions you may have, :)

Answer:

-48 ; - 16

Step-by-step explanation:

Given the expression :

X /4 = - 12

Multiply both sides by 4

X/4 * 4 = - 12 * 4

X = - 48

For the second :

X/2 = - 8

Multiply both sides by 2

X/2 * 2 = - 8 * 2

X = - 16

Answer:

-12 and 4

Step-by-step explanation:

-12+4=-8

(-12)*4= -48

Answer:

9.75

Step-by-step explanation:

Answer:

1

Step-by-step explanation:

Note that:

a = -4

b = 3

Plug in the corresponding numbers to the corresponding variables:

2a + 3b

2(-4) + 3(3)

Remember to follow PEMDAS. First multiply, then add:

2 * -4 = -8

3 * 3 = 9

-8 + 9 = 1

1 is your answer.

Answer:

26.65 or 58

Step-by-step explanation:

Answer: 30 cubic units

Step-by-step explanation:

Since the base has a volume of 2x3 or 6 and he plans on making the height 5 we must mutliply the base by height to get the new voulme so 6*5=30

Answer:

M= ([-1],[1/2])

The number in the green box is -1

Step-by-step explanation:

M= ([x1+x2/2], [y1+y2/2])

M= ([2+(-4)/2], [5+1/2])

M= ([-2/2, 6/2])

M= ([-1, 3])

umm whichever grade this is I don't know

Answer: 58.33π units ³

Step-by-step explanation:

The volume of a cylinder = πr²h

The volume of a cone = 1/3πr²h

Since we have been told that the volume of this cylinder is 175pi cubic units and that the cone has the same base area and the same height, then the volume of the cone will be the volume of the cylinder divided by 3. This will be:

= 175π / 3

= 175/3π

= 58.33π units ³

The volume of the cone is 58.33π units ³

Answer:

183
