Answer:

X= 124

Step-by-step explanation:

Because these angles are alternate interior angles we know that X+56 will equal 180, so to solve:

180 - 56= 124

Answer:

124 degrees

Step-by-step explanation:

180 degrees is a straight line

the given angle is 56 degrees

so, all you do is subtract

180 - 56 = 124

to double check,

56 + 124 = 180

Answer:

t×2.70=6

Step-by-step explanation:

this is only applicable if the price of one apple each is t.

Answer:

1 : 2

Step-by-step explanation:

The original ratio would be 3 : 6, so now you need to simplify it.

To simplify ratios, you divide the number on each side by their greatest common factor. The GCF(greatest common factor) for 3 and 6 would be 3, so divide 3 by 3 =1 and divide 6 by 3 =2, so then your simplified ratio of circles to triangles would be 1 : 2

Hope this helps! :)

Answer:

Depreciation for 1st year = 20/100 × 64000 = $12800

End of 1st year = $64000 - $12800 = $51200

Depreciation for 2nd year = 10/100 × 51200 = $5120

End of 2nd year = $51200 - $5120 = $46080

Answer:

Value at the end of the 2nd year is $46,080

Answer:

Value at the end of the 2nd year is $46,080

Step-by-step explanation:

Depreciation for 1st year = 20/100 × 64000 = $12800

End of 1st year = $64000 - $12800 = $51200

Depreciation for 2nd year = 10/100 × 51200 = $5120

End of 2nd year = $51200 - $5120 = $46080

Answer:

The change received by the customer is $7.

Step-by-step explanation:

First, write the given expression for the change when paying with $50.

[tex]50 - ( 14 + 12 + 2 ( 5 ) + 2 ( 2 ) + 3 )[/tex]

Evaluate the parentheses:

[tex]50-(26+10+4+3)[/tex]

Now add the numbers inside the parentheses.

[tex]50-43[/tex]

Subtract the numbers.

[tex]7[/tex]

Hence, the change received by the customer is $7.

Answer:

Given:

Entrance fee per student: $5(29)

Lunch costs: $4(29 + 6)

Bus fees: $25 + 8($2 + $3)

Total cost: 5(29) + 4(35) + 25 + 8(5)

To find:

The equivalent expressions of the total cost that use the properties of operations to simplify the math.

Solution:

We have,

Total cost = 5(29) + 4(35) + 25 + 8(5)

To simply this expression, we need to write 29 and 35 in the expand form or as the sum of their place values because it is easy to multiply a number with multiply of 10 and single digit.

Total cost = 5(20+9) + 4(30+5) + 25 + 40

Therefore, the correct option is B.

Answer:

(a) 259.5 days

(b) 284 days

Step-by-step explanation:

Let X represent the pregnancy length in days.

It is provided that [tex]X\sim N(270,9^{2})[/tex].

(a)

Let a represent the minimum pregnancy length that can be in the top 12% of pregnancy lengths.

Then,

P (X < a) = 0.12

⇒ P (Z < z) = 0.12

The corresponding z-score is, z = -1.17.

*Use a z-table.

Compute the value of x as follows:

[tex]z=\frac{x-\mu}{\sigma}\\\\-1.17=\frac{a-270}{9}\\\\z=270-(9\times 1.17)\\\\z=259.47\\\\z\approx 259.5[/tex]

Thus, the minimum pregnancy length that can be in the top 12% of pregnancy lengths is 259.5 days.

(b)

Let b be the maximum pregnancy length that can be in the bottom 6% of pregnancy lengths.

Then,

P (X > b) = 0.06

⇒ P (X < b) = 0.94

⇒ P (Z < z) = 0.94

The corresponding z-score is, z = 1.56.

*Use a z-table.

Compute the value of x as follows:

[tex]z=\frac{x-\mu}{\sigma}\\\\1.56=\frac{b-270}{9}\\\\z=270+(9\times 1.56)\\\\z=284.04\\\\z\approx 284[/tex]

Thus, the maximum pregnancy length that can be in the bottom 6% of pregnancy lengths is 284 days.

Answer and explanation:

The data we get from counting how many people entering a building in one minute is the sample of the population size. We do this since it would be tedious or not feasible to stand and count one by one how many people enter the building and so we do a good estimate with our one minute sample

Let's assume in one minute, 15 people enter the building and it takes one hour for everyone to enter the building

Population size would be 15*60 minutes= 900 people

Answer:

If two row interchanges are made in succession, then the determinant of the new matrix is equal to the determinant of the original matrix. ( A )

Step-by-step explanation:

A and B been n*n matrices the true statement would be ;  If two row interchanges are made in succession, then the determinant of the new matrix is equal to the determinant of the original matrix.

Although other options can be true for some matrices but they are not always true for every kind matrices but option A is always true

Answer:

3750 m

Step-by-step explanation:

This question can be solved using law of equation of motion

[tex]v^2 = u^2 + 2as[/tex]

where v is the final velocity

u is the initial velocity

a is the acceleration

and

s is the distance travelled

________________________________

given

final velocity = v = 0 since it is given that plane stops

u = 150 m/s

a = -3m/s2

using the above values in the given equation

[tex]v^2 = u^2 + 2as\\0 = 150*2 + 2*-3s\\0 = 22500 - 6s\\=> 6s = 22500\\=> s = 22500/6 = 3750[/tex]

Thus, plane will travel 3750 m before it stops.

Answer:

y = -2x + 5

Step-by-step explanation:

20 = 8x + 4y

subtract 8x from both sides

4y = -8x + 20

divide both sides by 4

y = -2x + 5

The value of y is 5-2x=y

Two or more expressions with an Equal sign is called as Equation.

The given equation is 20 = 8x + 4y

Twenty equal to eight times of x plus four times of y.

We need to solve the equation for y.

To solve this we need to separate the variable y.

Subtract 8x on both sides

20-8x=4y

Divide both sides by 4

20/4-8/4x=y

5-2x=y

Hence, the value of y is 5-2x=y
