George weeded 1/4 of the garden, and summer weeded, some too. When they were finished, 2/5 of the garden still needed to be weeded. What fraction of the garden did summer weed?

Answer:

0.21

Step-by-step explanation:

if you write it as a fraction it would be 21/100

and if that is made to a decimal it would be 0.21 .

Answer:

500

Step-by-step explanation:

it is a 3 digit number which means it is in the hundreds

Answer:

B. 7/16

Step-by-step explanation:

The answer to this question is the option whose value is closest to 1/2.

We know that the fraction 1/2 is 0.5, now we have to get that fraction out of all these fractions that is closest to the value 0.5

10/12 = 0.833

7/16 = 0.43

2/9 = 0.222

1/8 = 0.125

The value closest to 0.5 is obviously 0.43 from the above. Therefore we can conclude that the fraction 7/16 is closets to 1/2 given these other fractions.

Thank you!

Answer:

80p2 - 180r2

20(4p²-9r²)

20(2p+3r)(2p-3r)

Answer:

20(2p - 3r)(2p + 3r)

Step-by-step explanation:

Given

80p² - 180r² ← factor out 20 from each term

= 20(4p² - 9r²) ← difference of squares which factors in general as

a² - b² = (a - b)(a + b)

4p² - 9r²

= (2p)² - (3r)² ← with a = 2p and b = 3r

= (2p - 3r)(2p + 3r)

Thus

80p² - 180r² = 20(2p - 3r)(2p + 3r) ← in factored form

Answer:

y = 3x+7

Step-by-step explanation:

the slope of parallel lines are the same so the slope is 3

y-y1 = 3(x - x1)

y- 1 = 3(x- -2)

y-1 = 3x +6

y = 3x +7

Answer:

5

Step-by-step explanation:

45/9

Answer:

no solutions

Step-by-step explanation:

Given the 2 equations

y = - 7x + 8 → (1)

y = - 7x - 8 → (2)

Substitute y = - 7x - 8 into (1)

- 7x - 8 = - 7x + 8 ( add 8 to both sides )

- 7x = - 7x + 16 (add 7x to both sides )

0 = 16 ← not possible

This indicates the system has no solutions

Hey there!

The answer to your question is [tex]no[/tex] [tex]solutions[/tex]

To solve this, we will set the equations equal to eachother. We know that since the two expressions, [tex]-7x+8[/tex] and [tex]-7x-8[/tex] both equal [tex]y[/tex], then the expressions are equal. (Somebody comment what property that is, I forgot what it's called) So:

[tex]-7x+8=-7x-8\\[/tex]

Add [tex]8[/tex] to both sides:

[tex]-7x+16=-7x[/tex]

Add [tex]7x[/tex] to both sides:

[tex]16 = 0[/tex]

Therefore, there are [tex]no[/tex] [tex]solutions[/tex].

Have a terrificly amazing day!

Answer:

15.) -21f - 16

16.) 5s + 2t

Step-by-step explanation:

15.)

-12f - 16 - 9f (Distribute 4 through the parentheses)

-21f - 16 (Collect like-terms)

16.)

4s + 2t + s + s - s (Since two opposites add up to zero, remove them from the expression)

4s + 2t + s (Collect like terms)

Answer:

m∠PNO = 60°

m∠O = 33°

Step-by-step explanation:

∡NPO is 87° because it's a vertical angle with the 87° angle

3) ∡PNO is supplementary to the 120° angle (they must add to 180°)

4) m∠O = 180 - (60 + 87) = 33

Answer:

The answer is -

Number bond: 1 times 56 = 56.

Number bond: 4 times 14 = 56.

Number bond: 7 times 8 = 56.

Step-by-step explanation:

We can define a factor pair as a set of two factors, which, when multiplied together, give a particular product.

For example -

5 and 6 are factors of 30 because 5×6 = 30

Now,

Given -

Number bond: 1 times 56 = 56.                         ...................(1)

Number bond: 4 times 14 = 56.                         ...................(2)

Number bond: 5 times 6 = 56.                         ...................(3)

Number bond: 7 times 8 = 56.                         ...................(4)

In equation (1)

1 times 56 = 1×56 = 56

⇒1 and 56 are the factor pairs of 56

Satisfies

In equation (2)

4 times 14 = 4×14 = 56

⇒4 and 14 are factor pairs of 56

Satisfies

In equation (3)

5 times 6 = 5×6 = 30 ≠ 56

⇒5 and 6 are not factor pairs of 56

Not Satisfies

In equation (4)

7 times 8 = 7×8 = 56

⇒7 and 8 are factor pairs of 56

Satisfies

∴ we get

The answer is -

Number bond: 1 times 56 = 56.

Number bond: 4 times 14 = 56.

Number bond: 7 times 8 = 56.

Answer:

Area=36.66 cm^2

Step-by-step explanation:

First, you need the height.

Use the Pythagorean theorem:

hypotenuse^2=height^2+(1/2 base)^2  

It's one-half base because it's an equilateral triangle.

1/2 base =4.6

(9.2)^2-4.6^2=height^2

84.64-21.16=height^2

height^2=63.48

height=7.97

Area=(1/2)(base)(height)

Area=(1/2)(9.2)(7.97)=36.66 cm^2

Answer:
