A red kangaroo and a gray kangaroo together weigh 139 kg. The red kangaroo weighs 35 kg less than the gray kangaroo. How much does the gray kangaroo weigh?

Answers

Answer 1

Answer:

Gray kangaroo weighs 87 kg.

Step-by-step explanation:

Total weight of the two kangaroo = 139 kg.

Let the weight of the gray kangaroo be represented by p.

Since the red kangaroo weighs 35 kg less than the gray kangaroo = (p - 35) kg.

Thus;

weight of gray kangaroo + weight of red kangaroo = 139 kg

p + (p -35) = 139

p + p -35 = 139

2p = 139 + 35

2p = 174

p = 87

The weight of the gray kangaroo is 87 kg.

Weigth of the red kangaroo = (87 - 35)

                                               = 52 kg

Answer 2

The gray kangaroo weighs 87 kg.

let the weight of the gray kangaroo as G.

We have,

the red kangaroo weighs 35 kg less than the gray kangaroo.

So, the weight of the red kangaroo can be represented as G - 35.

We also know that the combined weight of the red kangaroo and the gray kangaroo is 139 kg. So we can write the equation:

G + (G - 35) = 139

Combining like terms:

2G - 35 = 139

Now, let's solve for G by isolating the variable:

2G = 139 + 35

2G = 174

Dividing both sides by 2:

G = 174 / 2

G = 87

Therefore, the gray kangaroo weighs 87 kg.

J/6 -9=5/6

Can u give me a step to step answer

Answers

Answer:

j = 59

Step-by-step explanation:

since you are solving for j, you want to get it by itself

you can start out by multiplying both sides of the equation by 6 to get rid of the fractions

[tex](6)(\frac{j}{6}-9)=\frac{5}{6}(6)[/tex]

distribute the 6

[tex]j-54=5[/tex]

add 54 to both sides

[tex]j-54+54=5+54[/tex]

[tex]j=59[/tex]

Which is not a pair of congruent angles in the diagram below?

A. Angles BDA and DBC

B. Angles ABD and BAD

C. Angles ABD and BDC

D. Angles BCD and BAD​

Answers

Answer:

B. Angles ABD and BAD

Step-by-step explanation:

The way that you tell which angles are congruent, are based on the angle marks. Angle A and C are congruent because they both contain 3 of the congruency marks, meaning they would equal the same degree. The answer is B because starting with angle BDA, B is your starting point, whereas D is the angle and A is the point you end on. With angle BAD, you start at point B and end at D, making angle A the one you're looking at. Because angle A contains 3 congruency marks, while angle B only contains one, this makes the two angles NOT congruent. Hope this helps. :)

Answer:

angles ABD and BAD

Step-by-step explanation:

The congruent angles match in the number of angle markings on the diagram.

Consider this equation 2,900 = 250 + 132.5T. In this situation, what would the solution
to this equation tell us?

Answers

Answer:

T = 20

Step-by-step explanation:

Given the equation 2,900 = 250 + 132.5T, to get the solution of the equation, we will find the value of T as shown;

From 2,900 = 250 + 132.5T

subtract 250 from both sides;

2,900- 250 = 250 + 132.5T-250

2,650 = 132.5T

Divide both sides by 132.5

132.5T/132.5 = 2650/132.5

T = 20

Hence the solution to the equation tells us that the value of T is 20

Answer:

Step-by-step explanation:

5x - (3+7)=9+2(x-8)

Add the numbers 3 + 7= 10

5x - 10= 9 + 2(x-8)

Expand 9 + 2(x-8): 2x - 7

5x - 10 = 2x - 7

Add 10 to both sides

5x -10 + 10 = 2x -7 + 10

Simplify 5x = 2x + 3

Subtract 2x from both sides

5x -2x = 2x + 3- 2x

3x = 3

Divide both sides by 3

Dominick wants to determine the maximum capacity of a cylindrical bucket that has a radius of 6 inches and a
height of 12 inches. What is the capacity of Dominick's bucket? Round your answer to the nearest tenth. Don't
forget the label.

Answers

Hey there! I'm happy to help!

To find the volume of a cylinder, you multiply the base by the height.

First, let's find the base.

The base is a circle. To find the area of a circle, you square the radius and multiply by 3.14 (pi).

6²=36

36(3.14)=113.04

We multiply this by the height.

113.04(12)=1356.48

And we round to the nearest tenth.So, the maximum capacity of Dominick's bucket is 1356.5 cubic inches. If you use the entire pi number you would get something more around 1357.2, so that could be the answer if the first is incorrect.

#SPJ1

Answer: A dilation will map shape I onto shape II. The bottom left coordinate of shape I is (1, 1) and the bottom left coordinate of shape II is (3, 3). So, to get the corresponding coordinates of shape II, multiply the coordinates of shape I by 3. This is true for every set of coordinates. So, the scale factor is 3. Because the scale factor is 3, which is greater than 1, the dilation is an enlargement.
