Answer:
DF = 57
Step-by-step explanation:
DE + EF = DF
(4x + 10) + (2x - 1) = 9x - 15
Combine like terms on the left side
6x + 9 = 9x - 15
Subtract 6x on both sides
9 = 3x - 15
Add 15 on both sides
24 = 3x
Divide by 3 on both sides
x = 8
DF = 9x - 15 = 9(8) - 15 = 72 - 15 = 57
Checking:
(4(8) + 10) + (2(8) - 1) = 9(8) - 15
(32 + 10) + (16 - 1) = 72 - 15
58 - 1 = 72 - 15
57 = 57
Answer:
DF= DE+EF
9x–15 = (4x+10)+(2x-1)
9x–15 = 6x +9
9x–6x= 9+15
3x = 24
x=24/3
x=8
DF = 9x –15 = 9(8)–15= 72 –15 = 57
So; DF = 57

What is 6 tenths, 2 hundredths, 8 thousandths in standard form?
A.0.0628 B.0.628 C.6.28 D.628
Answer:
B: 0.628
Step-by-step explanation:
Place value rules.
The value of each digit in a number is known as the place value. The number that has 6 tenths, 2 hundredths, and 8 thousandths can be written in the standard form as 0.628. The correct option is B.
What is the place value of a digit in a number?The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.
Identification of the place value of a digit in a number:
The place values on the left of the decimal point start as ones, tens, hundreds, and so on.The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths, and so onThe tens mean multiply by 10The tenth means the tenth part of that digit which is that digit divided by 10Given 6 tenths, 2 hundredths, 8 thousandths, this can be written in the standard form as,
Standard form = 0.6 + 0.02 + 0.008 = 0.628
Hence, the number that has 6 tenths, 2 hundredths, and 8 thousandths can be written in the standard form as 0.628.

You plan to cut a board into 3 pieces to repair part of a railing. You are going to cut the two ends of the board off into two equal pieces that are 3.1 feet long, if the remaining piece needs to be 2.27 times longer than the each of the first two cuts what length board should you buy? Round to the nearest tenth
Answer:
the answer might be 20
Step-by-step explanation:
first you add 3.1 to 3.1 to get 6.2
then you multiply 6.2 by 2.27
then you add the answer you get from that to 3.1+3.1 to get the final length to be 20.274 and that would be 20 in the nearest tenth

727÷9 Pleaase HEEEELLLPPP!!!!!!!!
Answer:
80.77777778
Step-by-step explanation:
when dividing 727 by 9, think about how many times does 9 go into 7? none.
next how many times does 9 go into 72? 8 times!
but since we have established 9 cannot go into 7 we need to know how many times does 9 go into 727, since it goes into 72 8 times already try adding a zero behind that 8. So what is 80(9)? it's 720. So the answer would be 720 with a remainder of 7. :)

1. Using the figure below to answer the question. If the sector (APB) has an area of 7pi and m<APB = 44°, find the radius length for circle P. (answer choices are 6.35, 9.27, 7.57, and 9.7)
Answer:
7.57
Step-by-step explanation:
the area = 44/360 × π × r²
7 π = 44/360 × π× r²
eliminate π
7 = 44/360 x r²
r² = 7× 360/44
r² = 57.27
r =√57.27 = 7.57
