Answer:

25 miles, and the cost will be $37.50.

Step-by-step explanation:

Mose's charge can be represented by f(x) = 0.5x + 25, Holly's charge can be represented by g(x) = 0.3x + 30.

Set the equations equal to each other: 0.5x + 25 = 0.3x + 30.

0.2x = 5

x = 25

Substitute 25 for x: f(x) = 0.5(25) + 25 = 37.5, g(x) = 0.3(25) + 30 = 37.5.

So f(x) = g(x) at x = 25, and the output will be 37.5.

Answer:

184

Step-by-step explanation:

Find the common difference first   d = 6 - 4 = 2

first term  a_1  = 4

a_n = (n -1)*d + a_1

a_91 = (91 - 1) * 2 + 4

a_91  is the 91st term:

a_91 = 90*2 + 4

a_91 = 180 + 4 = 184

Answer:

1. D

2. B

3. A

4. C

Step-by-step explanation:

1. The third side can't be calculated with given information

2. This is right triangle so you can use Pythagorean theorem to find hypotenuse.

6^2 + 8^2 = c^2

36 + 64 = c^2

100 = c^2

10 = c = PR

Since PM = RM, you would take half of c to find PM. So PM = 5

3. When writing congruency statement, you have to be careful with orders.

Angle A is congruent to angle E.

Angle B is congruent to angle D

So if A comes first, then E should be written first for the other side (does that make sense?)

4. For SAS, you need 2 congruent sides and 1 congruent angle. But that angle has to be in between two congruent sides.

Answer:

1. width = 4 inches length = 13 inches

2. 225 m²

Step-by-step explanation:

1. So we know there are two sides and one side is 9 more than the other.

We let one side be x as we don't know what the number is. The other side is x+9 as its 9 more than the first side but we don't what that is either.

We know the area of a rectangle is A = bh.

The two sides are x and x+9

so, x(x+9) = 52

x² + 9x = 52

x² + 9x - 52 = 0

x² + 13x - 4x - 52 = 0

x(x+13) -4(x+13) = 0

(x-4)(x+13) = 0

x = 4 x = 13

The answer is x = 4 because you can't have x = -13 as negative lengths don't exist.

So if one side is x and the other side is x+ 9. Then plugging in 4 to both gets us, 4 and 13 as the dimensions.

The length is 9 more than width so,

length = 13 inches and width = 4 inches.

2. We know the area of a rectangle is A = bh.

One side is x + 10 and the other is x+15

Area is 750.

(x+10)(x+15) = 750

x²+15x+10x+150 = 750

x²+15x+10x-600 = 0

x²+25x-600 = 0

(x+40)(x-15) = 0

x = 15 as we can't have x = -40 because negative distance does not exist.

The bistro has sides x and x.

So the area is x * x.

15 * 15 = 225 m².

Answer:

8

Step-by-step explanation:

If 8 is added to 3(√9) it is more than 10. If 10 and 3(√9) is added it is more than 8. If 8 is added to 10 it more than 3(√9).

Percentage is a way to describe a part of a whole. The production of the footwear that will be in 2016 will be 1.65 billion.

A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

It is given that the production of footwear in 2006 was 1.8 billion which will be reduced by 8.4%, therefore, the number of footwear that will be produced in 2016 is 91.6%(100%-8.4%) of the production in 2006. Therefore, the production of footwear in 2016 will be

[tex]91.6\%\ of\ 2006\\\\= 0.916 \times 1.8\ billion \\\\= 1.6488\approx 1.65\ billion[/tex]

Hence, the production of the footwear that will be in 2016 will be 1.65 billion.

Answer:

5:2 please give me brainliest

Step-by-step explanation:

Start with definition of absolute value, |x|.

It says, |x| = x, for any x >= 0 and

|x| = -x, for any x < 0

 Now, instead of x, we have the expression x+120 inside the absolute value brackets:

|x+120|

Play the same game as above - what is the absolute value here?

|x+120| = x+120 for (x+120)>=0 and

|x+120| = -(x+120) for (x+120)<0

Now, recognize that the last condition (x+120)<0 is the same as writing x<-120. That is the condition in the question. Therefore the absolute value |x+120| will equal the second expression (for that condition), namely -(x+120), or -x-120.

Answer:

A and C

Step-by-step explanation:

When you are dividing exponents you subtract. So for this problem -8 - -4 = -8 + 4 = -4. This means that the new exponent would be -4.

When you have a negative exponent, the equation is a fraction. As an example x^-5 would be equal to 1/x^5. For this equation, since you know that the new exponent is -4, an equivalent equation would be 1/3^4.

Answer:

RN = registered nurse

LPN = licensed practice nurse

RN earns $21.50 per hr

LPN earns $14 per hr

To calculate earnings for a 40 hour working week, multiply the rate per hour by 40:

RN earns:  21.50 × 40 = $860 per week

LPN earns:  14 × 40 = $560 per week

Difference:  860 - 560 = $300

Therefore, an RN is paid $300 more than an LPN for a 40 hour working week.

Number of weeks in a (non leap) year = number of days in a year ÷ 7

                                                               = 365 ÷ 7

                                                               = 52.14285714...

Rounding to the nearest whole number ⇒ 52 weeks in a year

To calculate the yearly salary, multiply the rate per week by 52:

RN earns:  860 × 52 = $44720 per year

LPN earns:  560 × 52 = $29120 per year

Difference:  44720 - 29120 = $15600

OR we can simply multiply the difference between the amount paid for a 40 hour week by 52:

⇒ 300 × 52 = $15600

Therefore, an RN is paid $15600 per year than an LPN.
