B) 64, because all these numbers have a difference of 14, and it you keep going, the 10th term will be 64.

Using the sequence, you can tell that this is an arithmetic sequence. Therefore, the common difference is 14. The formula is 14n - 76. Using this, plug in n=10 and the answer comes out to be 64, or B.

The length of a postage stamp is

AleksAgata [21]

<h3>Answer: Choice B</h3><h3>2W+2( W+4 1/4) = 124 1/2</h3>

=========================================

Explanation:

L = length

W = width

"The length is 4 1/4 longer than the width" (paraphrase) so

L = W + 4 1/4

This means,

P = perimeter = 124 1/2

P = 2L+2W

2L+2W = P

2W+2L = P

2W+2( L ) = P

2W+2( W+4 1/4) = 124 1/2

Your room surface area is 132 square feet. Express the surface area in square meters.

Leviafan [203]

Answer: 12.263 sqm

Step-by-step explanation:

1 square meter = 10.7639 square feet

132 square feet in meters would therefore be;

1 sqm : 10.7639 sqf

x sqm: 132 sqf

10.7639x sqm = 132sqf

x sqm = 132 / 10.7639

= 12.263 sqm

Bruce wayne splits his budget by using the ratio 13:7. For every $13 he spends on reaearch he donates $7 to local charities. If

Gennadij [26K]

Answer:

The money that Bruce Wayne donates to local charities last week was $5,600

Step-by-step explanation:

Let

x ----> the money that Bruce Wayne spend on research last week

y ----> the money that Bruce Wayne donates to local charities ls week

we know that

$\frac{x}{y}=\frac{13}{7}$

$x=\frac{13}{7}y$ -----> equation A

$x=y+4,800$ ----> equation B

equate equation A and equation B and solve for y

$\frac{13}{7}y=y+4,800$

$\frac{13}{7}y-y=4,800$

$\frac{6}{7}y=4,800$

$y=4,800(7)/6\\y=\$5,600$

therefore

The money that Bruce Wayne donates to local charities last week was $5,600

What is the value of x that will make each of the two ratios proportional?

PilotLPTM [1.2K]

Answer:

a=7, b=14

Step-by-step explanation:

a. 2/6=x/21

cross multiply=

2×21=x×6

then solve

42=6x

divide both sides by 6

x=42/6=7

b. 150/84=25/x

cross multiply=

84×25=150×x

then solve

2100=150x

divide both sides by 150

x=2100/150=14

 HOPE THIS HELPS.
