Hi there!

r=5.4

1.Add the terms:

[tex]22.68*4.2=5.4[/tex]

2.Divide the two terms:

[tex]22.68*4.2=5.4[/tex]

Therefore, r=5.4.

Answer:

2.50

Step-by-step explanation:

ok, so we start out with a 6 cup bag of cheese. But then she uses 2.25 cups to make lasgna, and 1.25 cups to make pizza. we need to see how much cheese is left after she used the cups. First lets add the 2 cups: 1.25 + 2.25. Lets first add 1 + 2 = 3, then .25 + .25 = .50. Lets now add 3, and .50, and that gives us 3.50. Now to see how much cheese is left, we must subtract 6 minus 3.50, which gives us a total of 2.50. I hope that helped!

Answer: 3/4 feet

Step-by-step explanation:Conversion a mixed number 3 5/

12

to a improper fraction: 3 5/12 = 3 5/

12

= 3 · 12 + 5/

12

= 36 + 5/

12

= 41/

12

To find new numerator:

a) Multiply the whole number 3 by the denominator 12. Whole number 3 equally 3 * 12/

12

= 36/

12

b) Add the answer from previous step 36 to the numerator 5. New numerator is 36 + 5 = 41

c) Write a previous answer (new numerator 41) over the denominator 12.

Three and five twelfths is forty-one twelfths

Conversion a mixed number 2 2/

3

to a improper fraction: 2 2/3 = 2 2/

3

= 2 · 3 + 2/

3

= 6 + 2/

3

= 8/

3

To find new numerator:

a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/

3

= 6/

3

b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8

c) Write a previous answer (new numerator 8) over the denominator 3.

Two and two thirds is eight thirds

Subtract: 41/

12

- 8/

3

= 41/

12

- 8 · 4/

3 · 4

= 41/

12

- 32/

12

= 41 - 32/

12

= 9/

12

= 3 · 3/

3 · 4

= 3/

4

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(12, 3) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 12 × 3 = 36. In the next intermediate step , cancel by a common factor of 3 gives 3/

Step-by-step explanation:

Answer:

5 triangles are in a heptagon.

Answer:

Your answer would be 189

Step-by-step explanation:

if you break the figure in to smaller parts you get for the two triangles 12*9/2. There are two of them, so that gets you 12*9/2+12*9/2, and all that equals 108. Finally, there is one more square in the middle, which equals 81, so 108+81=189, which is your answer.

Answer: 1875km 840m

Step-by-step explanation:

From the question, we are informed that Gupty travelled 75km 800m by car and travelled 1800km 40m by aeroplane.

The distance that she travel altogether will then be:

= 75km 800m + 1800km 40m

= 1875km 840m

Answer:

D because you divide both sides by x.

Step-by-step explanation:

They are equivalent if you divide both sides by x for A

Answer: $94.49

Step-by-step explanation:

125.99 x 25/100

125.99 x 0.25

you save = $31.50

final price = original price - discount

final price = 125.99 - 31.4975

final price = $94.49

The answer is H(t)=5(censored)(go do your work child)

Answer:

  126.9°

Step-by-step explanation:

The sine of an angle is the same as the sine of its supplement. The other solution in the interval is ...

  180° -53.1° = 126.9°

Answer:

[tex]\sqrt{85}[/tex] = 9.2195 = 9.22

[tex]\sqrt{17}[/tex] = 4.123

Step-by-step explanation:

Answer:

x ≈ 25.1

Step-by-step explanation:

Using the sine ratio in the right triangle

sin26° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{11}{x}[/tex] ( multiply both sides by x )

x × sin26° = 11 ( divide both sides by sin26° )

x = [tex]\frac{11}{sin26}[/tex] ≈ 25.1 ( to 1 dec. place )

"Correct" Answer:

53

Step-by-step explanation:

It's automadically 90 degrees because it's an acute angle, so you add 11 + 26 which gives you 37. Subtract 90 from 37 and it gives you 53, the variable.

26 + 11 = 37

90 - 37 = 53

Answer:

C. a shipwreck at -52 feet

Step-by-step explanation:

It is asking which is farthest from the ocean's surface, so we must use absolute value.

[tex] | - 22| = 22 \\ |48 | = 48 \\ | - 52| = 52\\ |19| = 19[/tex]

52 is greater than the others. therefore the farthest away.

Answer:

approximately 83%

Step-by-step explanation:

Answer:

83%

So basically you take 12-2=10 and then do 10/12 and that = 0.83 and so 83% is the answer

Answer:

Step-by-step explanation:

First replace f(x) with y

[tex]y=-2x+2[/tex]

Then switch the variables

[tex]x=-2y+2[/tex]

Solve for the new y value

[tex]x-2=-2y\\[/tex]

[tex]-\frac{x-2}{2} =y[/tex]
