Answer:

Step-by-step explanation:

Lets find out first the Area of the rectangle building

A=50*100=5000 ft^2

we have 2 circles with the radius of 42 ft, r=21ft

Acircle=3.14*(21)^2=1384.74

Area of 2 circles=2*1384.74=2769.48

What is not covered by the rings is

5,000.00-2769.48=2230.52, rounded is 2231

Choice A

Answer:

[tex]f(d) = 15 + 3d[/tex]

Step-by-step explanation:

Given

[tex]a = 15[/tex] --- day 1

[tex]Rate = 3[/tex] -- i.e. triples daily

Required

Determine the function f(d)

The number of customers on a particular day is:

Customers = Day 1 + Rate * Number of days

Represent as a function:

[tex]f(d) = a + Rate* d[/tex]

Where d is the number of days.

So, we have:

[tex]f(d) = 15 + 3* d[/tex]

[tex]f(d) = 15 + 3d[/tex]

Answer:

Step-by-step explanation:

Since there are 16 oz in 1 lb, to find the amount in 3 lbs, you would just multiply it by 3

16 · 3 = 48

to find the price you divide the total price by number of oz.

6.95 ÷ 48 ≈ 0.1448

since money is measured in hundreths, you would round up (because thats how money works) so it would be roughly 15 cents. unless your teacher wants you to round down to 14 cents

Answer:

  y +2 = -1/2(x -7)

Step-by-step explanation:

The line PQ has a rise of 6 units for a run of 3 units, so its slope is ...

  m = rise/run = 6/3 = 2

A line perpendicular to PQ will have a slope that is the opposite reciprocal of that, so ...

  -1/m = -1/2

We have the slope of the desired line, and a point it needs to pass through, so we can use the point-slope form of the equation of a line.

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

An equation for the desired line is ...

  y +2 = -1/2(x -7)

__

This can be rearranged to other forms.

  y = -1/2x +3/2 . . . . . slope-intercept form

  x +2y = 3 . . . . . . . . . standard form

Answer:50°

Step-by-step explanation:

Let x represent the scale factor, the ratios are multiplied by:

5x°+6x°+7x°=180°

18x°=180°

x=10

Smallest Angle 5x°=5(10)°=50°

Answer: x=10

Step-by-step explanation:

x/20=14/28

28x=14 times 28

x=10

Frank's pet store

Step-by-step explanation:

Assuming they want the most fish with 12 gallons, lets see how many we can get from each place

Sally's. 12/4 = 3

3 goldfish

Franks. 12/3 = 4

4* 4 = 16.

Frank's place can get you more fish

Answer:

1/4

Step-by-step explanation:

For a die,

the number of possible results is 6

The prime numbers are 2,3,5

the probability of getting a prime number is thus; 3/6 = 1/2

Tossing a coin, the probability of getting a head is also 1/2

So the probability of getting both on a single toss will be;

1/2 * 1/2 = 1/4

According to the question,

The number of possible results,

Prime numbers,

Now,

The probability of getting a prime number will be:

= [tex]\frac{3}{6}[/tex]

= [tex]\frac{1}{2}[/tex]

then, by tossing the coin head's probability is "[tex]\frac{1}{2}[/tex]".

hence,

Getting both on single toss will be:

= [tex]\frac{1}{2}\times \frac{1}{2}[/tex]

= [tex]\frac{1}{4}[/tex]

Thus the above answer is right.

Answer:

27°C

Step-by-step explanation:

The temperature on February 9th 1934 = -15°C

The next day the temperature rose 42 degrees.

We need to find an expression for the temperature on February 10th.

February 10th temperature = -15 + 42

= 27°C

So, the temperature on February 10th is 27°C.

Answer: it would be 42+(-15)

Answer:

Multiply both sides by -2 and reverse the inequality symbol.

Step-by-step explanation:

To isolate w, multiply both sides by the reverse of -1/2 (because -1/2*2=1 ), which is -2

When multiplying or dividing by negatives, you must reverse the inequality symbol as well.

To isolate the variable,  you multiply both sides by -2 and reverse the inequality symbol.

Isolation of variables means making the variable the subject of the formula from the given expression.

Given the inequality expression -1/2 w  < 12

To make w the subject of the formula, we will have to multiply both sides by -2 to have;

-1/2 w * -2 >  12 * -2
w > -24

Hence to isolate the variable,  you multiply both sides by -2 and reverse the inequality symbol.
