Answer:

The answer is Dilation of a scale factor of 4 followed by a reflection of the y axis.

Step-by-step explanation:

On the smaller triangle, the line EF has a length of 1 unit.

On the larger triangle, the line EF has a length of 4 units.

Therefore, the smaller triangle was dilated by 4, since 4x1 is 4.

The triangles was flipped over the y axis.

This means that it was reflected over the y axis.

Ball-Bearings, Inc. produces ball bearings automatically on a Kronar BBX machine. For one of the ball bearings, the mean diamete
kherson [118]

Answer:

3.6% of the ball bearings will have diameters of 20.27 mm or more.

Step-by-step explanation:

We can calculate this proportion using the z-score.

We have a normal distribution with mean 20.00 mm and standard deviation of 0.150 mm.

The value for X is 20.27 mm.

Then, the z-score and its associated probability are:

z=\dfrac{X-\mu}{\sigma}=\dfrac{20.27-20}{0.15}=\dfrac{0.27}{0.15}=1.8\\\\\\P(X>20.27)=P(z>1.8)=0.036=3.6\%

The length of a flea is approximately one million times longer than the width of DNA. Which is a reasonable measure for the widt
scZoUnD [109]

Answer:

The answer is A

Step-by-step explanation:

That is because one million has 6 digits and I'm guessing that the flea is measured in millimeters. So you just add the two decimal places. So, you add the one million (count the number of zeroes in a million) to the number of decimal places that the dot was moved. So from a measure of meter you move the dot one place right and you decrease the measuring unit. So, first is meter then centimeter and then millimeter.

Jason has $2 worth of dimes and quarters. He has 13 more dimes than quarters. By following the steps below, determine the number
Crazy boy [7]

Jason has $2 worth of dimes and quarters. He has 13 more dimes than quarters. The Number of dimes = 15 and Number of quarters = 2.

<h3>What is a linear equation?</h3>

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

The total money = $2 = 200 cents

Types of coins are dimes and quarters

Number of dimes are 13 more than quarters

let number of dimes be x and quarters be y

so our equation

10x + 25y = 200\\x = (y+13)\\10(y+13) +25y= 200\\10y + 130 +25y = 200\\\\35y + 130 = 200\\y = 70/35 = 2

What number does x stand for in this equation?<br><br> -7x + 6=27
AURORKA [14]
⓵ You need to solve the left side first in order to isolate the × and find it’s value :

-7× + 6 = 27
-6 -6
↓

-7× = 21
÷-7 ÷-7

↓

× = -3

If you find it too difficult to divide a number by a negative, just divide 21 by 7 and always remember that when dividing, when the signs are different the answer is negative. So knowing that you could just divide 21 by 7, which is 3, and add a negative sign in front!


I hope this helped, if there’s anything let me know! ☻
