James has dimes and quarters saved up in his change jar. He has a total of 162 coins totaling $31.20. James has dimes

Answers

The question is incomplete:

James has dimes and quarters saved up in his change jar. He has a total of 162 coins totaling $31.20 what is the total amount james has in quarters?

a. $10.00

b. $6.20

c.$15.50

d.$25.00

Answer:

d.$25.00

Step-by-step explanation:

With the information provided, you can write the following equations given that dimes are equal to 0.10 and quarters to 0.25 to determine the number of dimes and quarters that James has:

x+y=162 (1)

0.10x+0.25y=31.20 (2), where:

x is the number of dimes

y is the number of quarters

First, you can solve for x in (1):

x=162-y (3)

Then, you have to replace (3) in (2) and solve for y:

0.10(162-y)+0.25y=31.20

16.2-0.10y+0.25y=31.20

0.15y=31.20-16.2

0.15y=15

y=15/0.15

y=100

Finally, you have to replace the value of y in (3) to find x:

x=162-100

x=62

Now, you know that James has 100 quarters and you can multiply this number for the value of a quarter to find the amount James has in quarters:

100*0.25=25

According to this, the answer is that James has $25 in quarters.

Plzz I asked this three times! The Functions r and s are defined as follows.
r(x)=-2x+2
s(x)=x^2+2
Find the value of s(r(2)).

Answers

Answer:

s(r(2)) = 6

Step-by-step explanation:

You would first solve for r(2). You then input r(2) which equals -2 into s(r(2)).

r(x)= -2x + 2

r(2)= -2(2) + 2

r(2)= -4 +2

r(2)= -2

s(x)=x² + 2

s(r(2)) = (-2)² +2

s(r(2)) = 6

Find the perimeter of the figure to the nearest hundredth.​

Answers

Perimeter: 36.84 feet

Let’s start with the easy part...all the rectangle pieces 6 x 3 = 18 feet

We know from subtracting the rectangle length (6ft) from the total length (12 ft) that the diameter of the circle is 6ft.

Circumference = diameter x pi
= 6 x 3.14 = 18.84

We have the circle split into 2 halves, but the circumference remains the same

In AABC, what is AB to the nearest tenth?

Answers

Answer:

AB = 9.5 units

Step-by-step explanation:

Here, we want to find the measure of AB

To do this, we are going to make use of the sine rule

for the sine rule, the ratio of the measure of a side and the sine of the angle that faces the side is a constant value for a triangle

Thus, we have it that; in a triangle ABC

a/sin A = b/sin B = c/sin C

using the triangle given;

we need the measure of the angle at C

The sum of angles in a triangle is 180

thus;

C + 93 + 48 = 180

C = 180 - 93 -48

C = 39 degrees

Now, to get the value of AB;

AB/sin 39 = 15/sin 93

AB = (15 * sin 39)/sin 93

AB = 9.5 units

What is the measure, in degrees, of the missing interior angle?

A) 70

Step-by-step explanation:

180 - 120 = 60

? = x

x + 50 + 60 = 180

x + 110 = 180

x = 70

So we need it to equal 120
120-50 is 70
So your answer is 70

You have a triangle with one 70 degree angle and one 40 degree angle. What is the measure of the other angle? A) 40 degrees B) 70 degrees C) 60 degrees D) 180 degrees

Answers

Answer:

B) 70 degrees

Step-by-step explanation:

The sum of angles in a triangle = 180 degrees

We are given 2 angles in the triangle = 70° and 40°

The measure of the third angle is

180° = 70° + 40° + 3rd Angle

3rd Angle = 180° - ( 70° + 40°)

= 180° - 110°

= 70°

The measure of the other angle is 70°

Option B is the correct option.

Fourteen percent of the town's population is over the age of 65. If there are 320
residents over the age of 65, approximately what is the town's population?

Answers

Answer:

2,285.7143

Step-by-step explanation:

There are two ways of doing this.

#1: Take 320, and divide it by the 14%. This should get you how many people are eqivlelent to 1 percent. When I did it out, 320/14 is equal 22.857143...

Remember this is 1%, and we need to find 100%. So we need to multiply the 1%, which was 22.857143, by 100.

This should get you 2,285.7143.

#2 Take your 100%, and divide it by the 14% that make up the 65+ population. This should get you 7.1428571.

Now you just have to multiply this number by the amount of 65+ residents, which is 320. So you should multiply 320x7.1428571.

This should get you the same exact answer, 2,285.7143

When a bakery opened this morning, the ratio of the number of pineapple muffins to the number of mango muffins was 3 : 2. After 244 pineapple muffins were sold, the ratio of the number of pineapple muffins to the number of mango muffins changed to 3 : 5. How many pineapple muffins were there when the bakery opened this morning?

Answers

Answer:

(x+244)/y=3/2

x/y=3/5

y=5x/3

(x+244)/(x5/3)=3/2

x+244=3/2 . 5x/3

x+244=15x/6

6(x+244)=15x

6x+1464=15x

1464=15x-6x

1464=9x

x=1464/9

x≈ 162

mm=162*5/3=270

162:270 = 3:5

pm before = 270*3/2=405

405:270 = 3:2

Answers

Answer:

y = 150x

Step-by-step explanation:

There is a proportional relationship between number of computers sold (x) and profit generated (y)

y ∝ x

y = kx

Here, k = proportionality constant

From the table given,

At y = 450 and x = 3,

450 = k(3)

k = 150

Therefore, expression that represents the proportional relationship will be,

y = 150x

Answer:

Step-by-step explanation:

1000 milliters is 1 liter, so we would have to convert it to the ml so that it will all be in proportion. To simplify a ratio, divide by a number they can all be divided by. In this case, it was 10 first, so it made it 100: 30: 75. Then, to simplify it more, they can all be divided by 5, which is the lowest it can be since 20: 6: 15 have no numbers in common to be divided by.
