Explain step by step how to do 10.25 x .15.

Answers

Answer:

1.5375

Step-by-step explanation:

Multiply without the decimal points, then put the decimal point in the final answer

1025 x 15 = 15375

....

10.25 has TWO decimal places

0.15 has TWO decimal places

Therefore, when you multiply with the decimal points (10.25 x 0.15), the answer should have FOUR total decimal places.

So the answer is 1.5375

Yes that is the answer

Yesterday noah ran 2 1/2 miles in 3/5 hour. Emily ran 3 3/4 miles in 5/6 hour. Anna ran 3 1/2 miles in 3/4 hour how fast in miles per hour did each person run? Who ran the fastest? !!SHOW WORK!!

Answers

Answer:

Step-by-step explanation:

To calculate the speed of each one we proceed as follows:

speed=distance/time

a] Noah's speed:

distance=2.5 miles

time=3/5 hours

speed=(2 1/2)/(3/5)

=(5/2)/(3/5)

=5/2×5/3

=25/6

=4 1/6 mi/hr

Emily's speed

distance=3 3/4 miles

time=5/6 hour

thus

speed=(3 3/4)/(5/6)

=15/4)/(5/6)

=15/4×6/5

=4 1/2 mi/hr

Anna's speed:

distance=3 1/3 miles

time=3/5

speed=(3 1/3)/(3/5

=(10/3)/(3/5)

=10/3×5/3

=5 5/9 mi/hr

Anna was the fastest

Solve each system using the substitution method. Show all work and steps.

4.5.1) 2x-5y=8
x=3y-1


A. Substitute the equation that is already solved for one variable into the other equation.


B. Solve for the single variable in the one-variable equation.


C. Substitute the result from the previous step into x=3y−1 and solve for the unknown variable.


D. Write the solution as an ordered pair. E. Check the solution with the equation not used in Step C.

Answers

Answer: X=29

Step-by-step explanation:

First you substitute the x's: 2(3y-1)-5y=8

Then you open parenthesis:6y-2-5y=8

Combine like terms: y-2=8

Bring the 2 to the other side: y=10

Now you substitute the y with the answer: x=30-1

Easy equation: x=29

The answer will be x=29

What will be the result of substituting 2 for x in both expressions below?

1/2 x + 4
x + 6 - 1/2 x minus 2

Both expressions equal 5 when substituting 2 for x because the expressions are equivalent.
Both expressions equal 6 when substituting 2 for x because the expressions are equivalent.
One expression equals 5 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent.
One expression equals 6 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent.

Answers

Answer:pretty sure the answer is A

Step-by-step explanation:

1/2(2) + 4 = 1 + 4 = 5

2 + 6 - 1/2(2) -2 = 8 - 1 - 2 = 5

A jewelry maker is designing a crown. The crown must have at least 45 gems, using only emeralds, rubies, and diamonds. The number of rubies must be 1 less than 3 times the number of emeralds. The number of diamonds must be 4 less than the number of rubies. Which inequality could the jewelry maker use to find the fewest number of emeralds, x, that can be placed on the crown?

Answers

Answer:

Step-by-step explanation:

X is the variable and x means multiplication symbol.

X + (X x 3 - 1) + (X x 3 - 1) - 4) ≥ 45 is the answer I got.

Answers

1= -4

a negative plus a negative will always be a negative. Think of it as pouring 3 negatives and 4 negatives into a pot. You would just end up with 7 negatives

subtract 23-11 to get 12.

Answer:

The first one is -4 and the second one is 12. all you will need to do is change the + to a - then do for the first one which would be -7- -3= -4 so to check it you will need to use the + to check it so it will be -3+-4=-7. and for the second one you will need to do -11- -23=12 so to check it you will need to change the - to + so it will be set up as 12+ -23=-11.

Jack needs 22 pirates for every 2 pirate ships he manages.

Answers

Answer:

55, 121

Step-by-step explanation:

2*2 =4

22*2=44

but 4 is not the number we need and 4 is one less so we divide 22 by 2 and get 11 so 44+11=55

thats the first box.

The second box is 55*2+11 which is 121

55:is the first box

121 is the second empty box

55 pirates for 5 ships
And
122 pirates for 11 ships

22 pirates for every two ships that would be 11 pirates for every 1 ship so your basically adding 11 to every ship there

The ratio would be 11:1
