Mary made $176 for 8 hours of work. At the same rate, how much would she make for 17 hours of work?​

Answer:

see below!

Step-by-step explanation:

A) [tex]\frac{.15x + 25 + 48(.15)}{x + 48}[/tex] which can be simplified to [tex]\frac{32.2 + .15x}{x + 48}[/tex] = f(x)

B)

plug in 952 to x because x is the number of cookies left that you need to bake since 48 has been taken out already for the samples

[tex]\frac{32.2 + .15(952)}{952 + 48}[/tex] -----> [tex]\frac{32.2 + 142.8}{1000}[/tex]------> [tex]\frac{175}{1000}[/tex] ------> $0.175 or 17.5 cents

first let's name a couples of variable

• the number of adults tickets sold: a

• the number of children tickets sold: c

From the problem we know

a + c = 128

and

$5.40c + $9.20a = $976.20

1) solve the equation to alpha

a+c-c = 128 -c

a+0=128-c

a=128-c

2) substitute (128 - c) for a in the second equation and solve to c

$5.40c + $9.20a = $976.20 become

$5.40c + $9.20(128 - c) = $976.20

$5.40c + ($9.20 × 128) - ($9.20 - c) = $976.20

$5.40c - $9.20c + $ 1177.6 = $976.20

($5.40 - $9.20)c +$1177.6 = $976.20

-$3.80c + $1177.6 = $9.76.20

-$3.80c + $1177.60 - $1177.60 = $976.20 - $1177.60

-$8.30c + 0 = $201.40

-$3.80c = - $201.40

-$3.80c. -$201.40

A simple random sample involves taking a proportion from a population to represent the complete data set.

The books in the sample are: (b) 06 35 58 10 47

The numbers are given as:

85063 55810 10470 08029 30025

Rewrite the numbers as 2-digits as follows:

85 06 3 5 58 10 10 47 0 0 80 29 30 02 5

So, we have:

85 06 35 58 10 10 47 00 80 29 30 02 5

Remove numbers outside the range 01 - 70, the single digits and the repeated numbers

06 35 58 10 47 29 30 02

Take the first five samples

06 35 58 10 47

Hence, the books in the sample are: 06 35 58 10 47

Answer:

4m

Step-by-step explanation:

see image. The area of the trapezoid is

Area=1/2 (b1 + b2)h

We can fill in the area and the two bases that were given. Then we solve for h to find the height.

37.4 = 1/2 (6.4+12.3)h

Add inside the ( ).

37.4 = 1/2 (18.7)h

Multiply

the 1/2 × 18.7

37.4 = 9.35h

Divide by 9.35

37.4/9.35 = h

4 = h

The height is 4 meters

Answer:

y=4x-29

Step-by-step explanation:

y-y1=m(x-x1)

y-3=4(x-8)

y=4x-32+3

y=4x-29

Answer:

y = 4x - 29

Step-by-step explanation:

You will use the slope-intercept form y = mx + b

Your point (8, 3) will be substituted for (x, y) and 4 will be substituted for the slope(m)

y = mx + b

3 = (4)(8) + b

Simplify

3 = 32 + b; now subtract 32 from both sides to keep a balanced equation.

3 - 32 = 32 + b - 32

-29 = b

Finally, substitute your slope(m) = 4 and the y-intercept(b) = -29 back into the slope-intercept form

y = 4x - 29

The total fabric for shirts is 37.5 yards.

The total fabric for shorts is 45 yards.

The total fabric for each shirt and each pair of shorts is 5.5.

The amount of fabric leftover after making the shirts and shorts is zero.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

The company uses 2.5 yards of fabric for each shirt.

The company uses 82.5 yards of fabric to make shirts and shorts for 15 players.

Equation is 15 (2. 5 x) = 82.

Solution is x = 3.

Where x be each short.

Total fabric for shirts = 2.5 x 15

Total fabric for shirts = 37.5

The total fabric for shirts is 37.5 yards.

Total fabric for shorts = 3 x 15

Total fabric for shorts = 45

The total fabric for shorts is 45 yards.

The total fabric for each shirt and each pair of shorts will be

2.5 + 3

5.5

The total fabric for each shirt and each pair of shorts is 5.5.

82.5 - 15 (2.5 + 3)

82.5 - 15 (5.5)

82.5 - 82.5 = 0

The amount of fabric leftover after making the shirts and shorts is zero.

Answer:

Brandon has 18 Dimes and 33 Quarters  [Beware:  The problem does not state that Brandon owns the coins - he just has them.  Check your pockets]

Step-by-step explanation:

Let D and Q stand for the numbers of Dimes(D) and Quarters(Q).  I'll use pennies instead of dollars, so avoid the clutter of decimal points.

We are told that:

Q = 2D - 3  [The number of quarters is 3 less than twice the number of dimes.]

and

25Q + 10D = 1005   [total value of $10.05]

Substitute the value of Q in the first equation in the second, so that we have an equation with just one unknown, D.

25(2D-3) + 10D = 1005

50D - 75 + 10D = 1005

60D = 1080

D = 18

Q = 2D - 3

Q = 2(18) - 3

Q = 33

=============================

Check

25Q + 10D = 1005

25(33) + 10(18) = 1005  ?

825 + 180 = 1005  YES

----

Q = 2D - 3 ?

33 = 2(18) - 3    YES

Given

The airplane can seat up to 149 passengers.

If 96 passengers are already on the plane.

The solution to the inequality would be used to find how many more people can board.

Let x be the vacant seat.

So the equation will be.

x + 96 ≤ 149

On simplifying, then we get.

x + 96 ≤ 149

       x ≤ 149 - 96

       x ≤ 53

Thus, A solid circle is at 53. Everything to the left of the circle is shaded.
