Answer:

2 rolls of green ribbon

4 rolls of yellow ribbon.

Step-by-step explanation:

2 x 9 = 18

4 x 1 = 4

18 + 4 = 22

Answer:

total \: number \: of \: rolls = 6 \\ number \: of \: rollsof \:  \: green = x \\ number \: of \: rolls \: of \: yellow = 6 - x \\ then \:  \\ x \times 9 + (6 - x) \times 1 = 22 \\ 9x  +  6 - x = 22 \\ 8x  + 6 = 22 \\ 8x = 22  -  6 \\ 8x = 16\\ x =  \frac{16}{8} \\x =  2\\then \: number \: of \: green \:  = x = 2 \\ number \: of \: yellow = 6 - x = 6 - 2 = 4 \\ thank \: you

Which statement best completes the sentence below? If the measure of /_4 is 70^o, then the measure of /_8 is _________________.
Alex_Xolod [135]

Answer:

As given, measure of angle 4 is 70°

Then what would be the measure of ∠8.

Following cases comes into consideration  

1. If ∠4 and ∠8 are supplementary angles i.e lie on same side of Transversal, then

 ∠4 + ∠8=180°

⇒70°+∠8=180°  [∠4=70°]

⇒∠8=180°-70°

⇒∠8=110°

<u>2nd possibility</u>

But if these two angles i.e ∠4 and ∠8 forms a linear pair.Then

⇒ ∠4 + ∠8=180°

⇒70°+∠8=180°  [∠4=70°]

⇒∠8=180°-70°

⇒∠8=110°

<u>3rd possibility</u>

If ∠4 and ∠8 are alternate exterior angles.

then, ∠4 = ∠8=70°

<u>4th possibility</u>

If If ∠4 and ∠8 are corresponding angles.

then, ∠4 = ∠8=70°

Out of four options given Option A[ 110° because ∠4 and ∠8 are supplementary angles], Option B[70° because ∠4 and ∠8 are alternate exterior angles.] and Option D[70° because ∠4 and ∠8 are corresponding angles.] are Correct.

Antwan Campbell earns $494 per week. He is married and claims 1 child as a dependent. The state tax rate is 2.25% of taxable inc
DENIUS [597]

Answer:

$12.35

Step-by-step explanation:

Amount earned by Campbell per week = $494

Tax rate = 2.25 %

Amount withheld = 2.25% of his earning;

Amount withheld = 2.25 % of 494

Amount withheld = 0.025 * 494

Amount withheld  = $12.35

Hence the amount withheld from his weekly pay for state income tax is $12.35
