Two shelters offers dog adoption twice a year ruff had 123 dogs adoption in january 196 fogs adoption in July barks had 78 dogs adoption in January and 135 adoption in July estimates the difference in the number of dogs adoption at each shelter that year

Answers

Answer:

106

Step-by-step explanation:

ruff

123 dogs adoption in january

196 dogs adoption in July

Total adoption for the year = 123 + 196

Plzzz help

Answers

Answer:

[tex]121=6w[/tex]

Step-by-step explanation:

Formula for perimeter of a rectangle:

[tex]P=2l+2w[/tex]

[tex]w[/tex] = width

[tex]l[/tex] = length

Since the length is twice the width,

[tex]l=2w[/tex].

So, plugging these values into the formula, as well as the given perimeter of 121 feet, we get,

[tex]121 = 2(2w)+2w[/tex]

And after some simplification, we are left with,

[tex]121 = 6w[/tex]

Suppose v varies directly as g, and v = 36 when g = 4. Find v when g = 11

Answers

Step-by-step explanation:

v=kg

36=k×4

k=36/4

k=9

9=v/11
Multiply both sides by 11 to get rid of /11
99=v

Aggie is an australian exchange sudent in china, and she currenly has 14,000 yuan in her bank account. If the exchange rate changes from 1 australian dollar to 6.21 yuan to 1 australian dollar 6.37 chinese yuan, what happens to the value in australian dollars of the money in aggies bank account

Answers

Step-by-step explanation:

Amount in Aggie bank account = 14,000 yuan

Initial exchange rate:

1 Australian dollar = 6.21 yuan

Initial amount in Australian dollars will be;

x aus dollar = 14,000 yuan

cross multiply

6.21x = 14,000

x = 14,000/6.21

x =  2,254.428 australian dollars

If the exchange rate increases to 6.37 Chinese yuan, her new balance in Australian dollars will be y;

1 Australian dollar = 6.37 yuan

y Australian dollar = 14,000 yuan

cross multiply

6.37y = 14,000

x = 14,000/6.37

y = 2,197.80 Australian dollars

The change in her account balance due to increase in exchange rate is y-x

y-x = 2,197.80 - 2,254.428

y-x = -56.626 aus dollars

This negative values shows a decrease in her account balance by 56.626 aus dollars due to increase in the exchange rate.

suppose three Riders rode a total of 260 Mi if they use a total of 18 horses and rode each horse to the same number of miles how many miles did they ride before replacing the horse​

Answers

Answer:

14.3 - Not entirely sure?

Step-by-step explanation:

So you first divide 260 by 3 (the riders), and if they used a total of 18 horses together you then divide them by 3 as well. You get the answer from 260 and 3 (which would be 86) also the answer from 18 and 3 (which would be 6) and divide them together (I know, lots of dividing) and there's your answer! 14.3

A school nurse can give 25 eyes test in a two-hour period. How long will it atke the nurse to give eye test to all 600 student sin her school?

Answers

Answer:

96 hours

Step-by-step explanation:

25 eyes - 2 hours

1200 eyes* - x hours

[tex]x = \frac{2 \times 1200}{25} [/tex]

[tex]x = 96[/tex]

*each student has 2 eyes. So 600 students have 600×2=1200 eyes.

It will take the nurse 48 hours to give eye tests to all 600 students in her school.

What is Expression?

An expression is combination of variables, numbers and operators.

If the nurse can give 25 eye tests in two hours, then she can give 12.5 tests in one hour (since 25 divided by 2 equals 12.5).

To give eye tests to all 600 students, the nurse will need to give 600 tests in total.

Using the rate of 12.5 tests per hour, we can set up a proportion:

12.5 tests / 1 hour = 600 tests / x hours

Apply Cross-multiplication

12.5 tests ×  x hours = 600 tests

Divide both sides by 12.5 tests

we get,  x hours = 600 tests / 12.5 tests per hour

x hours = 48 hours

Therefore, it will take the nurse 48 hours to give eye tests to all 600 students in her school.

what's the distance between (-9,2) and (5,-4)?

Answers

Answer: Exact Form: d= 2√58

Decimal Form: 15.23154621...

Step-by-step explanation:

Distance formula: d=√(x2-x1)^2 + (y2-y1)^2

d=√(5- -9)^2 + (-4 - 2)^2

Exact Form: d= 2√58

Decimal Form: 15.23154621...

The distance between two points (-9,2) and (5,-4) is 15.23 units.

What is the distance between two points?

The distance between two points is defined as the length of the line segment between two places representing their distance. Most significantly, segments that have the same length are referred to as congruent segments and the distance between two places is always positive.

The formula of distance between two points is P(x₁, y₁) and Q(x₂, y₂) is given by: d (P, Q) = √ (x₂ – x₁)² + (y₂ – y₁) ².

We have to determine the distance between (-9,2) and (5,-4)

As per the question, substitute the known values in the formula,

d = √ {(-9 – 5)² + (2 – (-4))²}

d = √ {(-14)² + (6)²}

d = √ {196 + 36}

d = √232

d ≈ 15.23

Thus, the distance between the given two points is 15.23 units.
