I beive your doing "Order of Operations"

Heres some information.

Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Continue to preform multiplication and division from left to right. Next, add and subtract from left to right.

Answer:

The distance between two cities is 70 km.

Step-by-step explanation:

Given that,

The distance between two cities on a map is 3.5 centimeters.

It is also mentioned that the map uses a scale  in which 1 centimeter represents 20 kilometers.

We need to find the actual distance  between these two cities in kilometers.

1 cm = 20 km

3.5 cm = (3.5 × 20) km

= 70 km

Hence, the distance between two cities is 70 km.

Answer:Justin plans to spend $20 on sports cards. Regular cards cost $3.50 per pack and foil cards cost $4.50 per pack

number of packs of regular cards =r and the number of packs of foll cards = f

Cost of Regular card = 3.50

Cost of 'r' packs of regular card = 3.50r

Cost of Foil card = 4.50

Cost of 'f' packs of Foil card = 4.50f

Justin plans to spend $20 on sports cards so the sum of cost of regular and Foil cards should be less than or equal to 20

The inequality becomes

3.50r + 4.50f <= 20

Answer:

3,052.08 cm^3

Step-by-step explanation:

Here, we want to find the volume of the sphere

We have the formula as;

V = 4/3 * pi * r^3

The radius is 9 cm

V = 4/3 * 3.14 * 9^3

V = 3,052.08 cm^3

Answer:

b. P = 56,382(1+0.012)^t

The equation that defines the population in Smalltown t years after 2010 is [tex]P = 56,382(1 + 0.012)^t[/tex]

percentage, a relative value indicating hundredth parts of any quantity.

The population P after 2010 is an exponential growth function of the form:

[tex]P = P_{0} (1 + r)^t[/tex]

where P₀ is the initial population,

r is the annual growth rate as a decimal, and

t is the time in years.

Byu given information P₀ = 56,382,

r = 0.012, and

t is the number of years after 2010.

The equation that defines the population in Smalltown t years after 2010 is:

[tex]P = 56,382(1 + 0.012)^t[/tex]

Hence, equation that defines the population in Smalltown t years after 2010 is [tex]P = 56,382(1 + 0.012)^t[/tex]

Answer:

C. bisects that chord

Step-by-step explanation:

The radius of a circle is perpendicular to a chord if and only if it bisects the chord. Therefore, the option b is correct.

In the case when the diameter or the radius should be perpendicular with respect to the chord so it should be bisected the chord also its arc.

At the time when the two chords should be congruent so their corresponding arc should also be congruent.

Therefore, the option b is correct.

Answer: y = 3

Step-by-step explanation:  

So, we must find an equation of a line that passes through these two points such that we find the slope first as,  

m = (3-3) / (2-(-1)) = 0 / 3 = 0. Then we bring up the point-slope form of an equation to find the line such that  

y - y1 = m(x - x1). Next,  

y - 3 = 0(x - (-1))

y - 3 = 0..............Then add 3 such that the equation of a line is

Answer:

Step-by-step explanation:

Simplifying

5x + -4 = 40

Reorder the terms:

-4 + 5x = 40

Solving

-4 + 5x = 40

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + 5x = 40 + 4

Combine like terms: -4 + 4 = 0

0 + 5x = 40 + 4

5x = 40 + 4

Combine like terms: 40 + 4 = 44

5x = 44

Divide each side by '5'.

x = 8.8

Simplifying

x = 8.8

Answer:

y = kx for  fixed constant k

20 = k(4)  -->  20 = 4k --> k=5
