Answer:

2.6 kilograms

Step-by-step explanation:

Tebow weighs 3.2 and Tiger weighs 4.5, so adding those numbers together...

3.2 + 4.5 = 7.7

-3 + 4 = 7      

-0.2  + 0.5 = 0.7  

-7 + 0.7 = 7.7

Bear weighs 10.3 kilograms.

10.3 - 7.7 = 2.6

10 - 7 = 3

Now you had the 0.3 to the whole 3.

3.3 - 0.7 = 2.6

(Think of each number as a group of 10, and then subtract the decimal from it.)

Answer: 81 miles

Step-by-step explanation:

The total distance traveled on the three-day trip is: 81 miles.

Denote the total distance of each day's journey by D1, D2, and D3, respectively. Then write equations based on the given identities:

a. (5/8)D1 + 15 = D1

(3/8)D1 = 15

D1 = 40 miles

So, the total distance traveled on Day 1 is 40 miles.

b. 18 + (2/5)D2 = D2

(3/5)D2 = 18

D2 = 30 miles

So, the total distance traveled on Day 2 is 30 miles.

c. (5/11)D3 + 6 = D3

(6/11)D3 = 6

D3 = 11 miles

So, the total distance traveled on Day 3 is 11 miles.

Therefore, the total distance traveled on the three-day trip is:

40 + 30 + 11 = 81 miles.

Answer:

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

Answer:

$12.31

Step-by-step explanation:

Think of the original rate of pay as being 100%.

If your rate is increasing by 7%, it will now be 107% of the original rate (since 100% + 7% = 107%)

To find 107% of $11.50, convert 107% into a decimal

⇒ 107% = 107/100 = 1.07

then multiply this by the original rate to get the new increased rate:

⇒ $11.50 × 1.07 = $12.305

Rounding this to the nearest hundred = $12.31

Alternatively, you can find 7% of $11.50 and then add this to $11.50.

⇒ 7% = 7/100 = 0.07

Therefore, 7% of $11.50 = 0.07 × $11.50 = $0.805

Add this to the original rate:

$11.50 + $0.805 = $12.305

Rounding this to the nearest hundred = $12.31

Answer: Mila

Step-by-step explanation: First, you have to find the amount of orange beads Mila uses. First, you want to multiply 2 and 3 by 12, which results in 24 and 36. once you add them together, you get the total of 60. Next, you have to find the number of orange beads Ben uses. In order to solve the problem, you multiply 5 and 7 by 5, and the resulting numbers are 25 and 35. Once you add them together, you get a total of 60. Lastly, you can set up an equation, which results in 36 > 35. Therefore, Mia used more orange beads than Ben did.     Mia > Ben

Answer:

Part A:

6 feet

Part B:

Around 9.17 feet

Part C:

Around 3 feet

Step-by-step explanation:

Part A:

The Pythagorean Theorem (which is a^2 + b^2 = c^2), is the simpilist way to solve this. a = 8; c = 10. so, the problem becomes (64 + b^2 = 100). Subtract 64 from both sides to get (b^2 = 36). Square root both sides to get (b = 6).

Part B:

Using the same method, but with different measurements:

(a^2 + b^2 = c^2)

(16 + b^2 = 100)

(b^2 = 84)

(b = 9.17)

Part C:

The difference of 9.17 and 6 is 3.17. Therefore, the closest foot is 3. Hope this helps! Have a great day! :)

Step-by-step explanation:

(2/3)(-4)(9) = -24

(5/16)(-2)(-4)(-4/5)= -2

(-3/4)(7/8)=-21/32

(2 3/5) (7/9)=91/45

The correct answer is (D) -2x - 8.

To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:

-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3

Then we can simplify using the properties of multiplication and division:

-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3

Finally, we can combine like terms:

-2x - 5 - 3 = -2x - 8

The correct answer is therefore (D) -2x - 8.✅

Answer:

He can do 2/6 of his math homework in an hour.

Step-by-step explanation:

If there is 1/2 an hr. and you just double 1/6 to get 2/6.

Step-by-step explanation:

0.5% of w is 12 is what they are asking

0.5% of w = 12. Only the first answer has the equation equal to 12, so the first part is

\(12 = 0.005 \times w\)

Now to solve it, we want to get W alone, we can do that by dividing 0.005 on both sides. Since right now it's being multiplied we must do the opposite

\(w = \frac{12}{0.005} = 2400\)
