What is 60 scaled down by a factor of 1/10?
ERGENT

Answers

Answer 1
Comment
You can do this a number of ways.
The first way is to set up a proportion. That's very formal, and is most respected.

Proportion.
x / 60 = 1 / 10 The proportion is reduced by a factor of 10. Cross Multiply.
10 * x = 60 * 1 
10x = 60  Divide by 10
x = 60/10 
x = 6

Multiply by the scale factor.
Beginning number * scale factor = Final result.
60 * 1/10  = Final Result
60 * 1 / 10 = Final Result
Final Result = 6

This method words even when the numbers are quite complicated.

From a barrel of colored marbles , you randomly select 5 blue , 2 yellow , 3 red , 4 green , and 2 purple marbles. Find the expreimetal probability of randomly selecting a marble that is NOT yellow .

1. 9 / 16
2. 7 / 8
3. 8 / 9
4. 3 / 4

Answers

I think it's 7/8 because there's 16 marbles and 14 aren't blue so you have a 14/16 chance of not getting a yellow marble which simplifies to 7/8

Answer:

4/5

Step-by-step explanation:

From your experiment of drawing 20 marbles you now have a proportion of non-yellow marbles to total marbles and from that you can come up with an experimental probability that you'll draw a non-yellow marble.  

P(not yellow) = 16/20

How would you use a yardstick to measure the length of a rug

Answers

1 yardstick is equal to 1 yard, which is also equal to 3 feet. If you line the end of the yardstick up with the end of the rug, you can figure out 3 feet in. Then line the yardstick up at the 3 foot mark to determine where 6 feet is. Keep laying the yardstick across the rug until you have an overall estimate of how many feet you have. Add up the number of times you have laid the yardstick down and multiply by 3 feet.

If lines L and M are parallel in the given diagram and angle 5 is 132°, what is the measure of angle 3?

Answers

Hi,
The answer is 48 degrees.
How I got my answer:
Angle 5 + Angle 3  = 180(Co. Interior Angles)
let Angle 3 be x
132 + x = 180
x = 180 - 132
x = 48
The measure of Angle 3 is 48 degrees.
Hope this helps you.
Final answer:

Since lines L and M are parallel, corresponding angles such as angle 5 and angle 3 will be equal. Thus, if angle 5 is 132°, angle 3 will also be 132°.

Explanation:

This question concerns parallel lines and the angles formed by a transversal cutting across them. The lines L and M in the given diagram are parallel. Parallel lines have a special property where corresponding angles are equal. If angle 5 measures 132°, then the corresponding angle, angle 3, also measures 132°, because of this property of parallel lines.

The width of a large, rectangle-shaped tree farm is 1.9 kilometers. The best length of the farm is 4.4 kilometers. What is the best estimate of the area of the farm? Estimate 1.9 x 4.4

Answers

To make estimates, we usually round the numbers the nearest integer.
Since 1.9 is closest to 2 than it is to 1, the nearest integer of 1.9 is 2.
Similarly, since 4.4 is closest to 4 than it is to 5, the nearest integer of 4.4 is 4.

Now, to estimate the area of the farm, we are going to multiply our two integers:
Estimated Area of the Farm= [tex]2[/tex]x[tex]4=8[/tex]

Since 8 is between 4 and 10, we can conclude that the best estimate of the area of the farm is: between 4 and 10

The area of the base of the regular quadrilateral pyramid is 36 cm2 and the area of a lateral face is 48 cm2. Find: Surface area of the pyramid

Answers

Answer:

The surface area of the pyramid is [tex]228\ cm^{2}[/tex]

Step-by-step explanation:

we know that

The surface area of the Pyramid is equal to

[tex]SA=B+LA[/tex]

where

B is the area of the base of the pyramid

LA is the lateral area of the pyramid

In this problem we have

[tex]B=36\ cm^{2}[/tex]

Find the lateral area LA

Remember that the lateral area is the area of its four lateral faces

so

Multiply the area of a lateral face by 4 (because is a regular quadrilateral)

[tex]LA=(4)(48)=192\ cm^{2}[/tex]

Find the surface area SA

substitute the values

[tex]SA=36+192=228\ cm^{2}[/tex]

The surface area of the pyramid is 228 square cm.

What is the regular quadrilateral pyramid?

A pyramid is a three-dimensional shape. A pyramid has a polygonal base and flat triangular faces, which join at a common point called the apex.

The area of the base of the regular quadrilateral pyramid is 36 cm2 and the area of a lateral face is 48 cm2.

The surface area of the pyramid is;

[tex]\rm Surface \ area=B + LA[/tex]

Where; B is the area of the base of the pyramid, LA is the lateral area of the pyramid.

The area of a lateral face by 4 (because is a regular quadrilateral) is;

[tex]\rm LA=4(48)=192[/tex]

Substitute all the values in the formula;

[tex]\rm Surface \ area=B + LA\\\\\rm Surface \ area=36+192\\\\\rm Surface \ area=228[/tex]

Hence, the surface area of the pyramid is 228 square cm.

You would choose the arrow pointing to the right with a solid circle, and place it on the number line at the number positive 2.

Since his plant grows "at least" 2 inches per month, this means that it can grow that much or more.  This is the same as the inequality "greater than or equal to."

Since the plant can grow 2 inches per month, the circle is filled in at 2.  Since it can grow more than this, the arrow points to the right, which is the numbers greater than 2.

What is the surface area of the regular pyramid

Answers

The total area is the sum of the area of the base (65 m^2) and six times the area of one of the triangular sides.  This area (of one side) is (1/2)(base)(height), or (1/2)(5)(12), so the total area of the sides is 6(1/2)(5)(12) = 180 m^2.  Thus, the total area is 65 m^2 + 180 m^2 = 245 m^2.

Anne plans to increase the prices of all the items in her store but 5%. To the nearest cent how much will an artist saved if the artist buys a canvas and a frame that each measures 24 by 36 in before the price increase goes into effect. 24/36 canvas price 22.80 and the frame price is 89.98

Answers

Final answer:

The artist will not save any money, but will end up paying $24.06 more after the price increase.

Explanation:

To find out how much the artist will save, we first need to calculate the original cost of the canvas and frame. The price of the canvas is $22.80 and the frame is $89.98. Next, we calculate the price increase of 5% for both the canvas and frame. To do this, we multiply the original prices by 0.05. After that, we add the price increase to the original prices to get the new prices. Finally, we subtract the new prices from the original prices to find the amount saved by the artist.

The calculations are as follows:

Canvas price increase: $22.80 x 0.05 = $1.14New canvas price: $22.80 + $1.14 = $23.94Frame price increase: $89.98 x 0.05 = $4.50New frame price: $89.98 + $4.50 = $94.48Amount saved: ($22.80 + $89.98) - ($23.94 + $94.48) = $94.36 - $118.42 = -$24.06

The artist will actually end up paying $24.06 more after the price increase, rather than saving any money.

what is the equation of a circle with a center located at (4,-1) and a radius of 9

Answers

The equation for a circle with the given information would be (x - 4)^2 + (y + 1)^2 = 81.

This is because the base form of a circle is:

(x - x1)^2 + (y - y1)^2 = r^2

In which, x1 is the x coordinate of the center and y1 is the y coordinate of the center. r is the radius of the circle. So we plug in to those and simplify.

(x - 4)^2 + (y - -1)^2 = 9^2

(x - 4)^2 + (y + 1)^2 = 81

if the length of an arc is 12π inches and the radius of the circle us 10 inches, what is the measure of the arc?

Answers

You're dealing with "arc length" here, and the formula for that is   s = r*theta, where r is the radius and theta is the central angle in radians (not degrees).

Thus,   s = (12pi inches) = (10 inches)(theta), so

theta = the central angle (not the measure of the arc) = (12pi)/(10 inches), or

theta = 1.2*pi (no units of measurement)

Answer:

The measure of arc is 216°

Step-by-step explanation:

Length of arc, L = 12π inches

Radius of the circle, R = 10 inches

Formula: [tex]\theta=\dfrac{L}{R}[/tex]

Where, [tex]\theta[/tex] in radian.

By substituting L and R into formula.

[tex]\theta=\dfrac{12\pi}{10}[/tex]

[tex]\theta=\dfrac{6\pi}{5}[/tex]

Now we change radian to degree

[tex]\text{Degree }=\dfrac{\text{Radian}}{\pi}\times 180^\circ[/tex]

[tex]\text{Degree }=\dfrac{6\pi}{5\pi}\times 180^\circ[/tex]

Central angle = 216°

Hence, The measure of arc is 216°
