B: 5.9a + 5.6b

C: 5.9a - 5.6b

D: 5.6b - 5.9a

E: 5.9a - 5.6b (This is it’s simplest form)

Answer:3

Step-by-step explanation:

Answer: $37.8

Step-by-step explanation: To find the cost of the supplies we multiply $54 by .3 (the decimal version of 30%). The total is 16.2 . If we subtract this from the total amount we find the cost of the cleaning service. 54-16.2 = 37.8

Answer:

He does not have enough money left to buy a backpack for $37.50

Step-by-step explanation:

If he spent 40% of $60 on take out food, that means he spent $24.

So the remaining money would be $60-$24=$36.

So, no, he does not have enough money left to buy a backpack for $37.50

Answer:

The Stores profit is 70% or $59.5

How?

The reason is because if it's selling it for 100% of the price, then that means that the store bought it for 85 dollars, and it's selling it for 85 dollars, and that's 0% profit. But because the store has bought it for 100%, and then it's charging another 70% of the price, so the store's profit is 70%.

Now, we find 70% of 85 dollars, which will be the STORE'S PROFIT AMOUNT!

1. Convert percentages into fractions or decimals

For fraction: divide 70 by 100 and remove the % sign.

[tex]{70}\%=\frac{70}{100}[/tex]

For decimal: move the decimal point 2 places to the left and remove the % sign.

[tex]{70}\%=0.7[/tex]

2. Multiply the decimal or fraction by the quantity that equals 100%

[tex]100[/tex]%[tex]=85[/tex]

[tex]\frac{70}{100} *85=0.7*85=59.5[/tex]

Extra info:

170% of 85 = 144.5

70% of 85 = 59.5

15d=165

Step-by-step explanation:

15 dollars per dough (d)= 165 dollars

Hope this helps! ;-)

~Master Chief

Let's solve this problem step by step:

 So we know that Isaac sold 'x' number of tubs of dough

    ⇒ and that each tub of dough is worth 15 dollars

       ⇒  means he made '[tex]15*x'[/tex] dollars from selling 'x' tubs of dough

           ⇒ coincidently, we know that he made a total of $165

   ⇒ So the equation is: [tex]15x = 165[/tex]

Answer: 15x = 165

Hope that helps!

Answer:

1438 cm²

Explanation:

Rectangular prism area:  2(length × width + width × height + length × height)

Here given:

Find Surface Area:

2(19 × 11  + 11 × 17 + 19 × 17) = 2(719) = 1438 cm²

Answer:

1,1,2,5,6,7,10,10,13, 18, 19, 20, 24, 26, 27, 31, 36, 54, 63, 67

The average age  is  22 yrs

The sum  of the ages  is  440 yrs

When  two  of the turtles leave, the average is  21 yrs....and there are 18 turtles left

So....the sum of the ages is  21 * 18  = 378

And the difference  in the sums  is  62

The only two values that sum to 62  are  26 and 36

So.....the box turtle must have been 36 and the map turtle must have been 26

Step-by-step explanation:

The age of the escaped box turtle is 36 years in the reptile house of the Kalamazoo Zoo.

A stem-and-leaf diagram is a quantitative assessment of a collection of data in which the data values are divided into a "stem" (the first digit of the number) and a "leaf" (the remainder of the number) (the last digit of the number).

This stem-and-leaf plot shows the ages (in years) of the turtles in the reptile house of the Kalamazoo Zoo:

1,1,2,5,6,7,10,10,13, 18, 19, 20, 24, 26, 27, 31, 36, 54, 63, 67

To find the age of the escaped box turtle, we can first find the average age of all the turtles before the escape. To do this, we can add up all the ages and divide by the number of turtles:

(1+1+2+5+6+7+10+10+13+18+19+20+24+26+27+31+36+54+63+67)/20 = 26

The average age of the turtles remaining at the zoo after the escape is 1 year less than the average age before the escape, so the average age of the turtles remaining at the zoo is 26 - 1 = 25 years.

To find the age of the escaped box turtle, we need to subtract its age from the average age of the remaining turtles.

Let's represent the age of the box turtle X. We can set up the equation:

(1+2+5+6+7+10+10+13+18+19+20+24+26+27+31+36+54+63+67 - X)/19 = 25

We can solve this equation by multiplying both sides by 19 and then subtracting 67 from both sides:

1+2+5+6+7+10+10+13+18+19+20+24+26+27+31+36+54+63 - X = 475

Then we can add X to both sides to get:

1+2+5+6+7+10+10+13+18+19+20+24+26+27+31+36+54+63 -X + X = 475 + X

This simplifies to:

X = 36

Therefore, the age of the escaped box turtle is 36 years.

Answer:

Step-by-step explanation:

2 by 2

Answer: About 9.2

Step-by-step explanation:

  Since this is a right triangle, we can use the Pythagorean theorem. We are solving for the hypotenuse which is the "c" variable in the formula.

a² + b² = c²

7² + 6² = c²

7² + 6² = c²

49 + 36 = c²

85 = c²

[tex]\sqrt{85}[/tex] = c

9.2 ≈ c

Answer:

True

Step-by-step explanation:

To find true or false

Using the properties of logarithms, the left side of the given equation .logb b^2r=2r

, is equivalent to logb b^2r = 2x logb b

(use Power Rule)

=2x(1)

=2x

Hence, the given statement is a true statement.



Answer:

No

Step-by-step explanation:

The data is discrete and so there would be nothing to compare in terms of distribution as there are no similarities between the different categories.

First size: SA1 = 2B + Ph, where B = area of the base of the figure, P = perimeter of the base and h = height

SA1 = 2(12*7,2) + (12+7,2)*31 = 172.8 + 595.2 = 768 cm^2

Second size: SA2 = 2B + ph2 (where h2 is the new height, 31.9 cm)
SA2 = 2(12*7,2) + (12+7,2)*31.9 = 785.28 cm^2

It increases (by rounding it down) by 17 cm^2.

We will use the proper formula and solve.

Answer:

Step-by-step explanation:

1 hour equals 60 minutes

Find out how many pages per minute by dividing 1,520 pages by 60 minutes.

= 25.3333333

Therefore the machine prints 25.333333 pages per minute.

Multiply 25.3333333 by 15 minutes = 380

The machine can print 380 pages in 15 minutes.

You can check your work by finding out how many fifteen minute periods are in an hour (60/15=4), and multiplying 380x4

Since 15x4 is 60 and you can print 1520 pages in 60 minutes, you should be able to multiply 380x4 and get 1520 (spoiler alert! 380x4 is 1,520)

My explanation is below.

Step-by-step explanation:

rolling a six sided die and getting 7 = impossible

This is because a six sided die doesn’t even have the number 7 on it.

Randomly selecting a girl from a team of 14 boys and 4 girls = unlikely

This is because, if there are 14 boys and 4 girls, the girls have a lower chance of getting picked.

Randomly selecting a short straw from a set of 12 short straws and 12 long straws = neither likely nor unlikely

This is because the chance of picking a long straw is 12/24 and the chance of picking a short straw is 12/24 so it’s equal or neither unlikely or likely since you have a equal chance of picking either one.

Picking a bird from a list of 20 bird species and 6 other animals = likely

This is likely because, 20 is more than 6 and because there are 20 birds and 6 other animals, the birds are more likely.

Answer:

B) x²+2x-35=0; the factors are (x+7)(x-5)

Step-by-step explanation:

The quadratic equation which has the solutions as x = -7 and 5 may be x² + 2x - 35 = 0, the factors are (x + 7) and (x - 5) and (x + 7)(x - 5) = x² + 2x - 35.

Quadratic equations are polynomial equations of second degree.

The general form of a quadratic equation is ax² + b x + c = 0.

Given that,

a quadratic equation has the solutions x = -7 and 5.

There are two options, x² + 2x - 35 and x² - 2x - 35

Using the factorization method, a quadratic equation ax² + b x + c = 0 can be factored as (x + p)(x + q) where pq = c/a and p + q = b/a.

Consider, x² + 2x - 35 = 0

There are numbers 7 and -5 that 7 - 5 = 2 and 7 × -5 = -35

So it can factored as,

(x + 7) (x - 5) = 0

Solutions are x = -7 and x = 5

Hence the quadratic equation is x² + 2x - 35 = 0.
