A 35-meter length of cable is cut into pieces that measure 1.25 meters each. Into how many pieces is the cable cut?

Answers

It can be cut into 28 pieces. 
Final answer:

The cable is cut into 28 pieces.

Explanation:

To find how many pieces the cable is cut into, we can divide the total length of the cable by the length of each piece. In this case, the total length of the cable is 35 meters and the length of each piece is 1.25 meters.

Dividing 35 meters by 1.25 meters gives us:

35 m ÷ 1.25 m = 28 pieces

Therefore, the cable is cut into 28 pieces.

What number would come next in the sequence above, 4, 7, 10, or 12? Explain your answer.

Answers

The next number in the sequence will be 12.

Explanation

The given sequence is:   8, 15, 14, 9, 1, 6, 3

If we express these numbers in words, then we can see that the words are in alphabetical order, like....

Eight,  Fifteen,  Fourteen,  Nine,  One,  Six,  Three

There are two numbers 10 and 12 in the options which starts with letter 'T' , but  alphabetically 'Twelve' will be the next number after 'Three'

So, the next number in the sequence will be 12.

What is a parllogarm and how to work on it

Answers

A parallelogram is a quadrilateral where there are no right angles, the vertical sides are parallel to each other (usually slanted), and the horizontal sides are parallel to each other. All of the sides can be congruent but not always; the lines parallel to each other must also be congruent to each other though.

What kinds of symmetry do these letters and numbers have? Choosing best answer? What kind(s) of symmetry do these have? F 3 E Point, line, plane, or none?

Answers

Answers:

Letter F: none
Number 3: line and plane simmetry
Letter E: line and plane simmetry

Explanation:

1) point symmetry means that a rotation of 180° returns the same original figure.

None of the objects given result the same when you rotate them 180°, so none has point symmetry.

2) line simmetry is when the reflection accross a line returns the same original figure.

Both number 3 and letter E have symmetry accros a horizontal line that crosses them by the middle, which F does not.

3) Plane simmetry: exactly as with the line,number 3 and letter E have simmetry accross a plane that crosses them by the middle.

Runyon Company sells T-shirts ($5) and shorts ($6). If total sales were $1,040 and people bought 4 times as many T-shirts as shorts, what was the total number of T-shirts and shorts sold

Answers

Final answer:

To find the total number of T-shirts and shorts sold, set up equations using the given information. Solve the equations to find the values of the variables. Therefore, the total number of T-shirts and shorts sold is 200.

Explanation:

To find the total number of T-shirts and shorts sold, let's assign variables to the unknown quantities. Let T represent the number of T-shirts sold and S represent the number of shorts sold.

Given that people bought 4 times as many T-shirts as shorts, we have the equation T = 4S.

Since the total sales were $1,040, we can write another equation: 5T + 6S = 1040.

We can substitute the value of T from the first equation into the second equation to solve for S. Substituting 4S for T, we get 5(4S) + 6S = 1040. Simplifying this equation gives us 20S + 6S = 1040. Combining like terms, we have 26S = 1040. Solving for S, we find that S = 40.

Substituting this value back into the first equation, we can find T: T = 4(40) = 160.

Therefore, the total number of T-shirts and shorts sold is 160 + 40 = 200.

What expressions are equivalent to 6-10/6-4

Answers

Final answer:

To simplify the expression 6 - 10/6 - 4, divide 10 by 6 and subtract the result from 6, then subtract 4 from the previous result. The simplified expression is 0.33.

Explanation:

To simplify the expression 6 - 10/6 - 4, you need to follow the order of operations which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

To simplify the expression, we can perform the division first: 10/6 = 1.67.

Substituting the result back into the expression, we have: 6 - 1.67 - 4.

Next, we can perform the subtraction from left to right: 6 - 1.67 = 4.33, then 4.33 - 4 = 0.33.

Therefore, the expression 6 - 10/6 - 4 simplifies to 0.33.

Jed figures the promwill cost hin $160. He has saved $46 and can earn $6 an hour at his job. How many hours will he have to work?

Answers

The first step for finding out our equation is to know that the $6 depends on how many hours he works,, so it must have a variable with it. Along with that,, $46 will be out constant and we will equal our expression to the cost of prom ($160). This will look like the following:
6x + 46 = 160
Now that we have our equation,, we can start solving by moving our constant to the right side of the equation and changing the sign.
6x = 160 - 46
Now subtract the numbers on the right side.
6x = 144
Finally,, divide both sides of the equation by 6 to get your final answer.
x = 19
This means that Jed needs to work 19 hours to pay for prom.
Let me know if you have any further questions.

BRAINLIEST FOR WHO EVER GET THIS RIGHT triangle has a leg of 6 yards and a hypotenuse of 8 yards. What is the length of the other leg?

Enter your answer, as a decimal rounded to the nearest tenth, in the box.

Answers

using the Pythagorean theorem a^2 + b^2 = c^2
 where a and b are the legs and c is the hypotenuse
 so a = 6 and c = 8

lets solve for b

6^2 + b^2 = 8^2

36 + b^2 = 64

b^2 = 64 - 36
b^2 = 28

b = sqrt(28)
b = 5.29
b = 5.3 yards
