The measure of an angle is 15.4°. What is the measure of its supplementary angle?

Answer: y = 5.25x

Step-by-step explanation:

The cost of one pound of cheddar cheese is $5.25.

The number of cheese purchased is x.

The total cost of cheese would therefore be the cost of one pound of cheese multiplied by the number of pounds of cheese purchased:

= 5.25 * x

Full expression is therefore:

y = 5.25 * x

y = 5.25x

Answer:

x = 4

Step-by-step explanation:

The image provided below, I find very helpful when trying to solve difficult problems such as this one.

We use the same relationship, the only difference is we are given expressions and numbers for the segments

If the product of the segments in one chord equal the product of the segments in the other chord then,

x * 6 = 8 * ( x - 1 )

Or 6x = 8 ( x - 1 )

Now we solve for

Step 1 distribute the 8

8 * x = 8x

8 * -1 = -8

We now have 6x = 8x - 8

step 2 subtract 8x from each side

6x - 8x = -2x

8x - 8x cancels out

we now have -2x = -8

step 3 divide each side by -2

-2x / -2 = x

-8 / - 2 = -4

we're left with x = 4

Answer: 22.5

Step-by-step explain:

225/10=22.5

Given:

The exponential function is:

[tex]y=190(1.471)^x[/tex]

To find:

The percentage of increase or decrease.

Solution:

The general exponential function is:

[tex]y=a(1+r)^x[/tex]                   ...(i)

Where, a is the initial value,t is the time period, r is the rate of increase if [tex]r>0[/tex] and r is the rate of decrease if [tex]r<0[/tex].

We have,

[tex]y=190(1.471)^x[/tex]

It can be written as:

[tex]y=190(1+0.471)^x[/tex]         ...(ii)

On comparing (i) and (ii), we get

[tex]r=0.471[/tex]

Since [tex]r>0[/tex], therefore the given function is an increasing function.

[tex]r\%=0.471\times 100[/tex]

[tex]r\%=47.1\%[/tex]

Therefore, the percentage of increase is 47.1%.

Answer:

{14, 47, 50}

Step-by-step explanation:

The three sides of a right triangle must satisfy

a² + b² = c², known as the Pythagorean Theorem. So let's put the pairs into the theorem.

20, 48, 52

a² + b² = c²

20² + 48² = 52²

400 + 2304 = 2704

2704 = 2704

20, 48, and 52 represent the three sides of a right triangle.

40, 75, 85

a² + b² = c²

40² + 75² = 85²

1600 + 5625 = 7225

7225 = 7225

40, 75, and 85 represent the three sides of a right triangle.

14, 47, 50

a² + b² = c²

14² + 47² = 50²

196 + 2209 = 2500

2405 ≠ 2500

14, 47, and 50 do NOT represent the three sides of a right triangle.

13, 84, 85

a² + b² = c²

13² + 84² = 85²

169 + 7056 = 7225

7225 = 7225

13, 84, and 85 represent the sides of a right triangle.

14, 47, and 50 do NOT represent the three sides of a right triangle, therefore making it your answer.

Answer:

the paper need to be 16 inches

Answer:

25%

Step-by-step explanation:

Percentage change is the difference between the new price and the old price, divided by the old price.  Finally, multiply by 100 to convert the decimal answer to percent.

Difference in prices (new - old):  95 - 76 = 19

Divide by old price:  19/76 = .25

Multiply by 100%:  .25 x 100 = 25%

Answer:

The median score will stay at 91.

Step-by-step explanation:

First put the numbers in order from greatest to least:

87, 88, 91, 91, 95, 100

Then find the median (middle) because there are two in the middle that are the same, it's just that number.

Next, add the other numbers.

86, 87, 88, 88, 91, 91, 95, 98, 100, 100

Find the median again, which is still 91.

Answer:

Cost (10 guests ) = 50

Step-by-step explanation:

Given : Cost c = 10 + 4g (g refers to guests)

Equation : c = 10 + 4g

Putting no. of  guests 'g' = 10

c = 10 + 4 (10) = 10 + 40

c = 50

Answer:

The area is 2,000 cm2

Step-by-step explanation:

The answer is that because Area is when you multiply the length times the width ( l x w ). The length is 40 cm and the width is 50 cm and when you multiply them, you will get 2,000 cm2.

Answer:

No it does not

Answer:

It does not represent a function

Step-by-step explanation:

The values of x and y don't vary.

Answer:

20

Step-by-step explanation:

Pythagorean Theorem: a^2 + b^2 = c^2

21^2 + b^2 = 29^2

441 + b^2 = 841

Subtract 441 on both sides to get b^2 = 400

Take the square root of both sides to get b = 20

Remark

I hope you don't mind if I laughed a little at the graph. The y intercept of the line is at 10 dollars, but the rental car has not moved an inch. I guess they're charging you to look at your driver's license. It's late, and maybe I am a little giddy.

Begin by using a ruler (or some other straight edge) to join all the dots.

a) I'll spend a little time here. It is very important that you know how to read a chart and this question is your first step. The question is how many dollars does it take to go 40 miles? There is a system. Start with the 40 miles on the horizontal axis (x axis if you know that that is).

Use a ruler to go straight up until you hit the line.

b) This question is a guess.

c) This question is the exact reverse of the other two.

Answer:

a)1017.88 cm³

b)63.62 cm² (corr. to 2 d. p.)

c)452.39 cm²  (corr. to 2 d. p.)

d)579.63 cm²

Step-by-step explanation:

a) Volume = π x r x h = π x (9/2) x 16 = 1017.88 cm³

b) area of tin is used = circle = π x (9/2)² = 63.62 cm² (corr. to 2 d. p.)

c) area of cardboard is used = 2 x π x (9/2) x 16 = 452.39 cm²  (corr. to 2 d. p.)

d) total area surface = 2(63.62) + 452.39 = 579.63 cm²

Given:

A line is perpendicular to the line [tex]y=\dfrac{7}{2}x-13[/tex].

The line passes through the x-axis at 21.

To find:

The equation of the line in slope intercept form.

Solution:

The slope intercept form of a line is:

[tex]y=mx+b[/tex]

Where, m is the slope and b is the y-intercept.

The given line is:

[tex]y=\dfrac{7}{2}x-13[/tex]

So, the slope of this line is [tex]\dfrac{7}{2}[/tex].

The product of slopes of two perpendicular lines is -1.

Let m be the slope of required line. Then the slope of the required line is:

[tex]m\times \dfrac{7}{2}=-1[/tex]

[tex]m=-\dfrac{2}{7}[/tex]

The line passes through the x-axis at 21. It means the line passes through the point (21,0). So, the equation of the line is:

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-0=-\dfrac{2}{7}(x-21)[/tex]

[tex]y=-\dfrac{2}{7}(x)-\dfrac{2}{7}(-21)[/tex]

[tex]y=-\dfrac{2}{7}x+6[/tex]

Therefore, the equation of the required line is [tex]y=-\dfrac{2}{7}x+6[/tex].
