Which sequence of rigid motions will definitely work to take triangle GHJ onto triangle STU?

A.) Rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.

B.) Translate GHJ by the directed in segment GS. Translate G’H'J by the directed line segment H'T. Translate G"H"J" by the directed line segment J"T.

C.) Translate GHJ by the directed line segment GS. Rotate G’H'J using S as the center by angle H'ST Reflect G"H"J" over ST.

D.) Translate GHJ by the directed line segment GT. Rotate G’H'J using T as the center by angle H'ST. Reflect G"H"J over ST.

Answers

The answer is A I think

The correct option is A. Rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.

There are four types of rigid motions that we will consider translation , rotation, reflection, and glide reflection.

Here we have to rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.

Hence option A is correct that is Rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.

Find the value of earache missing variable

Answers

x = 9 because since they’re corresponding angles they would equal the same length so 11x -47 = 6x -2 and you add 47 to the opposite side so it would be 11x=6x + 45 and then do the same for 6x which would now be 5x=45 and then you divide 5 from both sides which equals 9

how do I solve −2(n− 9) + 4 using distributive property or combining like terms?

Answers

Answer:

Multiply the term outside of the parentheses by each term in the parentheses. To do this, you are essentially distributing the outer term into the inner terms. Multiply the term outside the parentheses by the first term in the parentheses. Then multiply it by the second term. If there are more than two terms, keep distributing the term until there are no terms left. Keep whatever operation (plus or minus) is in the parentheses

Step-by-step explanation:

in a school 46% of the 300 students are boys. how many girls are in the class than boy?

Answers

Answer:

138 of the students are boys, and 162 of them are girls. there are 24 more girls than boys.

Step-by-step explanation:

multiplying a number by its percent as a decimal gets you the percent of that number

300 x .46 = 138 boys

now subtract that from the original 300 to get the girls

300 - 138 = 162 girls

lastly subtract the girls from the boys to get how many more girls there are than boys

162 - 138 = 24

Sonya made a resolution to walk 2.5 kilometers a day. On Tuesday she walked 4 times around the running track at the local high school (each lap is 0.4 kilometers.) How many additional kilometers does Sonya need to walk? (HINT: this is a multi-step problem with 2 operations...)

Answers

Answer:

0.9km

Step-by-step explanation:

Given that:

Sonya's resolution = walk 2.5 km daily

Total distance walked on Tuesday = 4 times around a running track

1 lap = 0.4 km

Hence, total distance by walking 4 times around track :

0.4km * 4 = 1.6km

Additional kilometers Sonya needs to walk:

2.5 - 1.6 = 0.9 km

0 The product st is irrational.
The quotient is rational.
Previous
Pause

Answers

Answer:

The product st is irrational.

The product pt is irrational.

Step-by-step explanation:

Let p = 3/4 and q= 5/9

Now multiplying these two non zero rational numbers

3/4 (5/9)= 15/36 ( this is also a rational number)

An irrational number is one which cannot be expressed in the form of p/q where p and q are integers( in the form of a simple expression) like the rational number.

Now let the two irrational numbers  s and t be √3 and √5

Now multiplying the two irrational numbers we get

st = √3  √5

st =√15  ( this is also an irrational number)

√15 cannot be expressed in the form of a simple fraction.

Now multiplying pt

3/4 * √5= 3√5/4  ( this is also irrational)

5 pencils and 3 pens costs £11.
4 pencils and 6 pens costs £16.
Find the cost of a pencil.
Find the cost of a pen.

Answers

Answer:

The pencil is £1 and the pen is £2

Step-by-step explanation:

Let the pencil be p and let the pen be f.

5p + 3f = 11

4p + 6f = 16

the top one multiplies by two:

10p + 6f = 22

4p + 6f = 16    subtract

6p = £6

pencil = £1

Then you substitute the value of the pencil into the equation and find the value of the pen.

Today, a bicycle rider rode her bike 5 1/2 miles to raise money for her school. Yesterday, she rode 6 1/4 miles her grandfather said he would give her 2$ for every mile she rode. How much money did she earn?

Answers

Answer:

.125 or 1/8

Step-by-step explanation:

The question is looking for the difference divided by the long ride. The long ride is 6 1/4 miles, so now we need to find the difference.

In order to do this, we take the larger distance and subtract the smaller distance.

We would take (Tip: Use decimals when you can. They are easier to work with ) 6.25 - 5.5 and we get .75 or 3/4 of a mile.

Now, we put .75 over 6.25 and simplify.

22$ simplified

x: 90 degrees. y: 43 degrees

We know that x is a right angle. The way we find y is to add 47 + 90 which gives us 137. We also know that a right triangle adds up to 180. So, we subtract 137 from 180. This means that y would be 43 degrees.
