Step-by-step explanation:

Real numbers are basically all numbers, even uncountable ones, which are irrational numbers.

Answer:

  B

Step-by-step explanation:

AB and CD are the same length, so the construction will be one that shows addition of same-length segments. In choices A and C, XY > YZ. In choice D, XY < YZ. Only choice B shows addition of same-length segments.

As a check, you can compare the length of AB or CD to XY or YZ. You will find they are approximately the same, as they should be.

Answer:

$40 is the sales price after a 20% discount.

(*Edited as the shoes are $50.00, not $60.00)

Step-by-step explanation:

When calculating discounts, we can convert the percentage to a decimal and multiply by the original sales price:

[tex]50(.20)[/tex]

Multiply.

[tex]50(.20)=10[/tex]

Subtract your product from the sales price.

[tex]50-10[/tex]

Subtract.

[tex]50-10=40[/tex]

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

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.

Answer:

D w = 12ft, l = 32ft

Explanation:

Make an equation for your length based on the given information.

l = 2w + 8

Make an equation using what you know about the perimeter

p =2l + 2w, p = 88

88 = 2l +2w

Substitute in your previous equation for l.

88 = 2(2w + 8) + 2w

Distribute and simplify.

88 = 4w + 16 + 2w

88 = 6w + 16

72 = 6w

w = 12

Now you can solve for l using the first equation.

l = 2(12) + 8

l = 32

Your answer is w = 12fr, l = 32ft. You can check your work by plugging the values back into the perimeter equation.

Answer:

Step-by-step explanation:

From the question all the angles are on a a straight line which means the sum of their angles is 180 and one of the angles is 90°

So to find m [tex] \angle[/tex] 6 , add

m [tex] \angle[/tex] 5 and 90 and subtract the result from 180°

That's

m[tex] \angle[/tex]5 + m[tex] \angle[/tex]6 + 90 = 180

m[tex] \angle[/tex]6 = 180 - 90 - m[tex] \angle[/tex]5

m[tex] \angle[/tex]6 = 180 - 90 - 22

We have the final answer as

Hope this helps you

In the question, a lines & angles diagram is provided, and we can see three angles labelled here. The angles are angle 5, angle 6 and a 90°.

GiveN,

We have to find the measure of the missing angle 6...

All the three angles are lying on a staright line, so their collective measure or the sum of these 3 angles is equals to 180°.

➝ Angle 5 + Angle 6 + 90° = 180°

➝ 22° + Angle 6 + 90° = 180°

➝ Angle 6 + 112° = 180°

➝ Angle 6 = 68°

So, the measure of Angle 6:
