Answers

Answer:

2^-2

Step-by-step explanation:

When multiplying indices or exponents with the same base number, you can add the powers:

2^4 x 2³ = 2^7 (4 + 3 = 7)

2^5 x 2^4 = 2^9 (5 + 4 = 9)

When dividing indices or exponents with the same base number, you can subtract the powers:

2^7 ÷ 2^9 = 2^-2 (7 - 9 = -2)

Triangle EFG is congruent to triangle JKL.
What is KL, in units?

Answers

Applying the theorem of congruent triangles, since FG = 6 units and FG and KL are congruent, therefore:

KL = 6 units

Recall:

Congruent triangles have the same shape and size.Congruent triangles have all corresponding angles and side lengths congruent to each other.

Given that:

[tex]\triangle EFG \cong \triangle JKL[/tex],

therefore,

EF = JK

FG = KL, and

EG = JL

Thus, since FG = 6 units and FG and KL are congruent, therefore:

KL = 6 units

The 10 largest soccer and football stadiums have a capacity of at least of 1 x 105 people. Each stadium has 8 events each year for 10 years.

How many total people attended these events if every event was seated to capacity? Select ALL that apply

A

С

D

at least 8 x 107

E

at least 80 x 107 people

Answers

We have 10 stadiums each holding 105 people.
If each stadium has 8 events each year that’s 80 events per year in total.
So there is 800 events throughout the 10 years (each year holding 80 events).
To find the total number of people that attended the event we multiply the number of people that attended each event by how many events we had in total (105x800=84000)
So, C,D and E apply.

Answer:

324 ft²

Step-by-step explanation:

Given 2 similar figures with ratio of sides a : b , then

ratio of areas = a² : b²

Here ratio of sides = 3 : 18 = 1 : 6

ratio of areas = 1² : 6² = 1 : 36

That is the area of the larger parallelogram is 36 times the smaller

area of larger parallelogram = 36 × 9 = 324 ft²

Place the following steps in order to describe how to solve the following equation: ​ ​ 2(2x+3)-2=5

Answers

Answer:

0.25

Step-by-step explanation:

First, you distribute the equation.

2(2x+3)-2=5

4x+6-2=5

Then, you combine like terms.

4x+6-2=5

4x+4=5

Next, you subtract 4 from each side.

4x+4=5

4x+4-4=4x

5-4=1

4x=1

Finally, you divide each side by 4.

4x/4

For any two real numbers, a and b one and only one of these relations is true:
1. a = b
2. a < b
3. a > b

Answers

Answer:

For real numbers according to the Law of Trichotomy,

if a = b then a will never be greater than b and a will never be less than a.

if a<b then a will never be equal to b and a will never be greater than b.

if a>b then a will never be less than b and a will never be equal to b.

And vice versa to b as well.

That means only one property will hold for given two numbers.

3x-5y-7=0
X=2k-1.
Y=k

Answers

Answer:

x = 19

y = 10

Step-by-step explanation:

3x - 5y - 7 = 0

x = 2k - 1

y = k

3x - 5y = 7

x = 2y - 1

3 * (2y - 1) - 5y = 7

6y - 3 - 5y = 7

6y - 5y = 10

y = 10

x = 2 * 10 - 1

x = 19
