Answer:

Yes, the bill is absolutely accurate

Step-by-step explanation:

Cost of materials= $ 678.12

Final  bill amount(given)=$1206.12

Rate= $32 per hour for 16.5 hrs

Total amount for 32 hrs = time * rate = 16.5* 32=$528

Therefore, by the problem ,

Cost of materials+ Total amount  for 32 hrs = Final bill amount

= 678.12+ 528

=1206.12

Therefore , the final bill amount is 100% accurate as it completely matches with the given bill amount

Answer:

x= 11.33 years

Step-by-step explanation:

Y1= −19.76x + 227

Y2= = –92.57x + 1052

Y1 = Y2

–19.76x + 227 = –92.57x + 1052

Collect like terms and Simplify

-19.76x + 92.57x = 1052 - 227

72.81x = 825

Divide both sides by 72.81

x= 825 / 72.81

=11.33 years

Therefore,

x= 11.33 years

The solution for x is 11.33 years.

Given,

The linear function that models the population of rainbow smelt is[tex]y_{1} = -19.76x + 227[/tex]

The linear function that models the population of bloater fish is [tex]y_{2} =-92.57x + 1052[/tex]

Since, According to the question,

[tex]y_{2}=y_{1}[/tex]

[tex]-19.76x + 227 =-92.57x+1052[/tex]

On solving for x

[tex]-19.76x + 92.57x = 1052 - 227[/tex]

[tex]72.81x = 825[/tex]

Divide both sides by 72.81

[tex]x= \dfrac{825}{72.81}[/tex]

[tex]x=11.33 \ years[/tex]

Hence the solution for x is 11.33 years.

Answer:

The range is 10 cm.

Step-by-step explanation:

The range of a set is the difference of the largest and smallest values of the set. Looking at the data, we see that 30.98 cm is the largest value and 20.98 is the smallest value so the range is 30.98 - 20.98 = 10 cm.

Answer:

The answer is

Step-by-step explanation:

To calculate the range in a given set of data subtract the lowest observation from the highest observation

From the question

The highest measurement = 30.98 cm

The lowest measurement = 20.98 cm

So the range is

30.98 cm - 20.98 cm

Answer:

adult cost £7, child cost £2

Step-by-step explanation:

let a represent an adult and c a child , then

2a + 3c = 20 → (1)

a + 4c = 15 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate a

- 2a - 8c = - 30 → (3)

Add (1) and (3) term by term to eliminate a, that is

- 5c = - 10 ( divide both sides by - 5 )

c = 2

Substitute c = 2 into either of the 2 equations and evaluate for a

Substituting into (2)

a + 4(2) = 15

a + 8 = 15 ( subtract 8 from both sides )

a = 7

The cost of an adult ticket is £7 and a child ticket is £2

Answer:

According to the statement, the equation is :

Sides of regular octagon T= 3 × the length of sides of regular octagon G

The required equation is x = 3y

Where x is the length of the sides of the octagon T and y is the length of the side of the octagon G.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 5 - 9 is an equation.

We have,

Sides of regular octagon T = x

Sides of regular octagon G = y

Now,

The equation of the sides of regular octagon T is three times the length of the sides of regular octagon G can be written as:

x = 3y

Thus,

The equation is x = 3y.

A sailboat traveling 120m in 60s is 20.

Answer:

Step-by-step explanation:

Plug in the value of y & z in the expression

[tex]\frac{3}{2}y-3+\frac{5}{3}z=\frac{3}{2}*6-3+\frac{5}{3}*3\\\\\\=3*2 - 3 + 5 *1\\\\\\= 6 - 3 + 5\\\\\\= 3 + 5\\\\\\= 8[/tex]

Answer: 11

Step-by-step explanation:

If y=6 and z=3 then your problem will look like this : 3/2(6) - 3 + 5/3(3)

Put both 6 and 3 over 1 to turn them into a fraction and then multiply

3/2 multiplied by 6/1 is 18/2 which reduces to 9

5/3 multiplied by 3/1 is 15/3 which reduces to 5

Then your problem will look like this : 9 - 3 + 5

Follow order of operations and add and subtract from left to right

9 - 3 is 6 and 6 + 5 is 11

So your answer is 11

Answer:

38.89%

Step-by-step explanation:

the whole p8e chart is 360° as a perfect circle would be,

so : 360° - ( 66° + 144° ) = 360° - 210° = 140°

140° of the pie chart was cast in favor of candidat C.

(140° ÷ 360°) × 100 = 38.89%

6.0435*10²⁴

Step-by-step explanation:

Moon:  7.35*10²²

Earth: 5.97*10²⁴

7.35*10²² = 0.0735*10²⁴

then:

0.0735*10²⁴ + 5.97*10²⁴ = (0.0735 + 5.97)*10²⁴

=  6.0435 *10²⁴

Step-by-step explanation:

1. 1/6d - 8 = 5/8

1/6d -8 + 8 = 5/8 + 8

1/6d = 69/8

1/6d / 1/6 = 69/8 / 1/6

d = 51.75 or [tex]51\frac{3}{4}[/tex]

2. 3x - 4 + 5x = 10 - 2z

Answer:

40°

Step-by-step explanation:

e = 20°

d = 20°

c = 140°

b = 40°

If one angle in the circle is 20° then the measure of b is 40°.

Alternate exterior angles are those angles which are formed when two parallel lines are intersected by a transversal line and angle formed outside is known as alternte exterior angles.

When we observe the angles then we can say that d and 20° angles are alternate exterior angles. We can say that b=2d.So we have to put the value of d in the above formula to get the value of b.

b=2*20

=40°

Hence if one angle in the circle is 20° then the measure of b is 40°.

The correct option is;

Shirt Express charges less per shirt. For the cost to be the same 74 shirts must be ordered

Step-by-step explanation:

1) The given table for Shirt Express can be used to find the equation of the total cost of each made by Shirt Express as follows;

The rate of change of the function m is given as follows;

[tex]m = \dfrac{y_2 - y_1 }{x_2 - x_1}[/tex]

Therefore, we have;

m = (438 - 353)/(50 - 40) = 8.5

Te equation in slope and intercept form is then y - 438 = 8.5(x - 50)

From which we have;

y = 8.5·x - 8.5×50 + 438 = 8.5·x + 13

y = 8.5·x + 13

Therefore, Shirt Express initially charges 13 per shirt which is less than the 50 Shirt Custom charges

2)  the cost to be the same, we equate both shirts equations to get;

8.5·x + 13 = 8·x + 50

0.5·x = 50 - 13 = 37

x = 37/0.5 = 74 shirts

Therefore, for the cost to be the same 78 shirts must be ordered
