Let's call the number ' Q '.

The question says that (4Q) - (-10) = -18

Add -10 to each side:

4Q = -28

Divide each side by 4 :

Q = -7

Answer:

PQR reduction of ABC in the ratio 16/24=2/3

PR =x = AC*2/3 = 30*2/3=20

QR = y= BC*2/3 = 9*2/3=6

Step-by-step explanation:

Answer:

x=20cm

y=6cm

Step-by-step explanation:

We are told ΔABC and ΔPQr are similar. This means their corresponding sides are in ratios to one another.

That means the ratio of AB to PQ, is equal to the ratio of AC to PR, is equal to the ratio of BC to QR. Written mathematically, this is:

$(AB)/(PQ) =(AC)/(PR) =(BC)/(QR)$

Find x/PR

Since we know the values of AB, PQ, and AC, we can use $(AB)/(PQ) =(AC)/(PR)$ to find PR (x):

$(AB)/(PQ) =(AC)/(PR)$

$(24)/(16) =(30)/(x)$

1.5= $(30)/(x)$

1.5x=30

x=20

Find y/QR

Since we know the values of AB, PQ, and BC, we can use $(AB)/(PQ) =(BC)/(QR)$ to find QR (y):

$(AB)/(PQ) =(BC)/(QR)$

$(24)/(16) =(9)/(y)$

1.5= $(9)/(y)$

1.5y=0

y=6

Mr. and Mrs. Ferguson are planning a vacation to celebrate their anniversary.Mrs. Ferguson is considering reserving a room at the Abraham Hotel. The Abraham Hotel charges $239 a night.

Mrs. Ferguson calculates that 6 nights will cost $1450. What is the percent error in Mrs. Ferguson’s calculation? Round to the nearest percent. Show your work.

HELP ME

Answers

First, let's calculate the actual cost.
$239*6=1434$ is the actual cost of six nights.
The formula for percent error is $|(measured value-accepted value)/(accepted value)|*100$
The bars (|) stand for absolute value which gets rid of the negative sign if there is one.
Plug in the values: $|(1434-1450)/(1450)|*100$
$|(-16)/(1450)|*100$
$|-0.0110344828|*100$
$0.0110344828*100$
$1.10344828%$ is the percent error.

you have the numbers 1-25 written on slips of paper. if you choose one slip at random, what is the probability that you will select a number that divisible by 4

Answers

since there are 25 numbers there is 6/25 chances to pull a number divisible by 4 if you want a percent you divide the numerator 6 by the denominator 25 which is 0.24 then you move the decimal over to the right twice and you get 24%

How do I solve 1/7 +2/7

Answers

1/7+2/7=3/7 because you only add the numerator not the denominator

Answer: 3/7

Here are two methods to solve this problem.

1. Count on, since you have the same denominator.

1/7, 2/7, 3/7.

2. Add, but not counting on.

1 + 2 = 3

3 = 3/7.

Hope it helps!
