Answer:

$44.15 spend by tyrell if he buys the regular school lunch 9 days and buys ala carte 4 days .

Step-by-step explanation:

As given

When Tyrell buys the regular school lunch he spends $2.75.

On some days he buys ala carte he spends $4.85.

Tyrell buys the regular school lunch 9 days and buys ala carte 4 days.

Than

Tyrells spends money when he buys regular school lunch 9 days and ala carte 4 days = 9 × 2.75 + 4 × 4.85

                    = 24.75 + 19.4

                    = $44.15

Therefore $44.15 spend by tyrell if he buys the regular school lunch 9 days and buys ala carte 4 days .

What is 96-8c=20-12
galben [10]

Answer:

c = 11

Step-by-step explanation:

96 - 8c = 20 - 12 , that is

96 - 8c = 8 ( subtract 96 from both sides )

- 8c = - 88 ( divide both sides by - 8 )

c = 11

What is an equation of the line that passes through (2,2) and is parellel to the line y=7x
laila [671]

Answer:

Therefore, equation of the line that passes through (2,2) and is parellel to the line y=7x is y=7x-12

Step-by-step explanation:

Given:

a line y=7x

To Find:

Equation of line passing through ( 2, 2) and is parellel to the line y=7x

Solution:

y=7x     ...........Given

Comparing with,

y=mx

Where m =slope

We get

Slope = m = 7

We know that parallel lines have Equal slopes.

Therefore the slope of the required line passing through (2 , 2) will also have the slope = m = 7.

Now the equation of line in slope point form given by

(y-y_{1})=m(x-x_{1})

Substituting the points and so we will get the required equation of the line,

(y-2)=7(x-2)=7x-14\\\\y=7x-12......Equation\ of\ line

Therefore, equation of the line that passes through (2,2) and is parellel to the line y=7x is y=7x-12

A city has a vacant lot in the shape of an isosceles trapezoid and the city workers are installing a fence around the lot. What
ValentinkaMS [17]

Answer:

Length of the fence required = 135 m

Step-by-step explanation:

Total length of the fence required to cover the vacant lot = Perimeter of the isosceles trapezoid

Perimeter of ABCD = AB + BC + CD + AD

Since, AB = BC = EF = ED = 25 m

From the given right triangle BEC,

m∠EBC = m∠ECB = 45°

ΔBEC will be an isosceles triangle.

So, BE = EC

By Pythagoras theorem,

BC² = BE² + EC²

25² = 2(EC)²

EC = \frac{25}{\sqrt{2}} =17.7 m

And DC = (DF + EF + EC)

             = EC + EF + EC [Since, DF = EC]

             = 2EC + EF

             = 35.4 + 25

             = 60.4 m                            

Hence. perimeter of ABCD = 25 + 25 + 60.4 + 25

                                              = 135.4 m

                                              ≈ 135 m

Therefore, length of the fence required = 132 m
