Answer:

88.5

Step-by-step explanation:

100:113*100 =

(100*100):113 =

10000:113 = 88.5

The map tells you 1 inch = 0.5 miles.

Multiply each dimension on the map by 0.5 to get the miles, then add them together:

House to Sports store = 2 x 0.5 = 1 mile.

Sports store to Jay's house = 3.75 x 0.5 = 1.875 miles.

Jay's house to park = 1.5 + 0.5 = 2 inches x 0.5 = 1 mile.

Total distance = 1 + 1.875 + 1 = 3.875 miles.

The total distance covered in miles is; 3.875 miles

From the map, we see that;

1 inch = 0.5 miles.

Now, total distance in inches is;

D = 2 + 3.75 + 1.5 + 0.5

D = 7.75 inches

Using the given conversion rate to miles, we have;

D = 7.75 * 0.5

D =  3.875 miles.

Answer:

The function intersects the y-axis at point (0.9) (vertex)

Step-by-step explanation:

we know that

The equation of a vertical parabola into vertex form is equal to

[tex]y=a(x-h)^{2}+k[/tex]

where

(h,k) is the vertex of the parabola

if a>0 then the parabola open upward (vertex is a minimum)

In this problem we have

[tex]y-x^2=9[/tex] -----> [tex]y=x^2+9[/tex]

This is a vertical parabola open upward

The vertex is the point (0,9)

The vertex is a minimum

see the attached figure to better understand the problem

The graph does not intersect the x-axis (the function has no real roots)

The function intersects the y-axis at point (0.9) (vertex)

A) To find A in terms of B, we need to find A = xB. One given is A = 12 and B = 3. We substitute, which gives us 12 = x4. Divide both sides by 4, which gives us x = 3. This means that A = 3B.

B) For this, we can just plug in 5 as B in our equation. A = 3*5 -> A = 15.

C) We can plug in A as 36. 36 = 3B -> B = 12.

A.) The formula for A in terms of B is A = 4B. B.) When B = 5, A = 20. C.) When A = 36, B = 9.

A.) To find the formula for A in terms of B, we can set up a proportion using the given values. Since A is directly proportional to B, we can write the proportion as A/B = k, where k is the constant of proportionality. Substituting the values A = 12 and B = 3, we have 12/3 = k. Solving for k, we find k = 4. Therefore, the formula for A in terms of B is A = 4B.

B.) To find the value of A when B = 5, we can substitute B = 5 into the formula A = 4B. A = 4(5) = 20.

C.) To find the value of B when A = 36, we can rearrange the formula A = 4B to solve for B. Dividing both sides by 4, we get B = A/4. Substituting A = 36, we have B = 36/4 = 9.

Answer:

256/81

Step-by-step explanation:

The exact form is 256/81.

For this case we have that by definition of power properties:

[tex]a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}[/tex]

We have the following expression:

Answer:

Step-by-step explanation:

Let p represent the number of calories in a peach and g the number of calories in an orange.  

Then p = g + w.

From this we get g = p - w.

In words:  "The number of calories we get from an orange is equal to p, the number of calories from a peach, less w calories."

The midsegment is half the length of the base.

1) 32 ÷ 2 = 16

So, 16 is the midsegment

2) 11 ÷ 2 = 5.5

So, 5.5 is the midsegment

3) 32 ÷ 2 = 16

So, 16 is the midsegment

4) 14 ÷ 2 = 7

So, 7 is the midsegment

Answer:

169pi feet^2.

Step-by-step explanation:

The diameter = 26pi / pi = 26 feet and the radius = 13 feet.

The area  = pi r^2 = 13^2 pi

Step-by-step explanation:

Answer:

18 km/h

Step-by-step explanation:

Let S km be the distance between ports M and N, x km/h be the speed of the motorboat in still water. Then x-2 km/h is the speed of the motorboat upstream and x+2 km/h is the speed of the motor boat downstream.

1. The motorboat traveling downstream covers the distance between port M and port N in 6 hours, then

[tex]\dfrac{S}{x+2}=6[/tex]

2. Once, the motorboat stopped 40 km before reaching N, turned around, and returned to M. This took the motorboat 9 hours. Then

[tex]\dfrac{S-40}{x+2}+\dfrac{S-40}{x-2}=9[/tex]

From the first equation [tex]S=6(x+2)=6x+12.[/tex] Substitute it into the second equation:

[tex]\dfrac{6x+12-40}{x+2}+\dfrac{6x+12-40}{x-2}=9,\\ \\\dfrac{6x-28}{x+2}+\dfrac{6x-28}{x-2}=9.[/tex]

Now

[tex]\dfrac{(6x-28)(x-2)+(6x-28)(x+2)}{(x-2)(x+2)}=9,\\ \\(6x-28)(x-2+x+2)=9(x^2-4),\\ \\(6x-28)\cdot 2x=9x^2-36,\\ \\12x^2-56x-9x^2+36=0,\\ \\3x^2-56x+36=0,\\ \\D=(-56)^2-4\cdot 3\cdot 36=2704,\\ \\x_{1,2}=\dfrac{56+\sqrt{2704}}{2\cdot 3}=\dfrac{56\pm52}{6}=\dfrac{2}{3},\ 18.[/tex]

The speed of the motorboat cannot be less than the speed of the current, thus, x=18 km/h.

The speed of the motorboat in still water if the speed of the current is 2 km/hour is 18 km/hour.

Suppose the distance between port M and N =d

Suppose the speed of the motorboat in still water =x

The speed of the current =2 km/h (given)

So, the downstream speed of the boat = (x+2)

Upstream speed of the boat = (x-2)

Speed is the distance covered in unit time.

According to the question, a motorboat travelling downstream covers the distance between port M and port N in 6 hours.

This means, [tex]\frac{d}{x+2} =6[/tex]

So, [tex]d=6(x+2)[/tex]

Distance covered by the motorboat when the motorboat stopped 40 km before reaching N = d-40

=[tex]6(x+2)-40[/tex]

=[tex]6x-28[/tex]

So, [tex]\frac{6x-28}{x+2} + \frac{6x-28}{x-2} =9[/tex]

So, [tex]x=18[/tex]

[tex]x=\frac{2}{3}[/tex](not possible)

Therefore, the speed of the motorboat in still water if the speed of the current is 2 km/hour is 18 km/hour.

Step-by-step explanation:

we have

[tex]8(5x-9)[/tex]

Applying the distributive property

taking the outer term and multiplying it by each term inside the parenthesis

so

[tex]8(5x-9)=8*5x-8*9[/tex]

[tex]40x-72[/tex]

Answer:

[tex]8(5x - 9) = 40 x - 72[/tex]

Step-by-step explanation:

Let a, b, and c be any real number. Then

[tex]a(b + c) = ab + bc[/tex]

This is called the distributive property.

The given expression is

[tex]8(5x - 9)[/tex]

Or

[tex]8(5x + - 9)[/tex]

Let a=8, b=5x and c=-9

We apply the distributive property to obtain:

[tex]8(5x - 9) = 8 \times 5 x + 8 \times - 9[/tex]

We simplify to get:

[tex]8(5x - 9) = 40 x - 72[/tex]

Answer:

he earns $24 a hour

Step-by-step explanation:

31,200 divide by 52 (that is how many weak's are in a year) = 600

600 divide by 24 = 24

:)

Ms. Juarez earns $24 per hour.

To determine how much Ms. Juarez earns each hour, we need to find her annual salary first.

Since Ms. Franklin earns $31,200 per year and Ms. Juarez earns the same amount annually, Ms. Juarez also earns $31,200 per year.

Next, we calculate the number of hours Ms. Juarez works in a year. She works 25 hours per week, and there are 52 weeks in a year:

Weekly hours x Number of weeks = Total yearly hours

25 hours/week x 52 weeks/year = 1,300 hours/year

To find her hourly wage, we divide her annual earnings by the number of hours she works in a year:

Annual salary / Total yearly hours = Hourly wage

$31,200 / 1,300 hours = $24 per hour

Therefore, Ms. Juarez earns $24 per hour.

Keep on mind that:

[tex](a-b)^2=a^2-2ab+b^2[/tex]

Apply the quadratic formula:

[tex]x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}\\\\x=\frac{-(-2)+/-\sqrt{(-2)^2-4(0.5)(-2.5)}}{2(0.5)}\\x=-1\\x=5[/tex]

366 muffins

Step-by-step explanation:

28 x 12 = 336

5 x 6 = 30

336 + 30= 366 muffins

The total number of muffins the store ordered is, 366

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A store ordered 28 boxes holding 12 banana muffins each and five boxes holding 6 blueberry muffins each.

Hence, Number of banana muffins is,

⇒ 28 x 12 = 336

And, Number of blueberry muffins is,

⇒ 5 x 6 = 30

Thus, The total number of muffins the store ordered is,

336 + 30 = 366 muffins
