2x2 = 4 4x 10 = 40 x 32 = ?

Answer:

40%

Step-by-step explanation:

percent change in Mike's long distance runs = (change in miles ran / initial longest mile ran) x 100

change in miles ran = new personal record - initial personal record

14 - 10 = 4

(4/10) x 100 = 40%

Answer:

p=1, 2, 3

Step-by-step explanation:

p<3.25

p=1, 2, 3

Answer:

Step-by-step explanation:

I attached a pic so you can see what the angles look like when you draw them out and construct right triangles out of them. We need to find the missing side lengths, ?, in each triangle. For A:

and

x = 40 For B:

and

x = 29. Now that we know all the sides of each triangle, we will use the sum identity for sin:

sin(A + B) = sinAcosB + cosAsinB. Filling in what we found in our triangles for each ratio: sin A = 40/41, sin B = 21/29, and cos B = 20/29

sin(A + B) = which simplifies to

And that's it. It doesn't simplify any further.

a = 22 × Cos( 60 )

a = 22 × 1/2

a = 11

Answer:

a = 11

Step-by-step explanation:

[tex]sin 60 = \frac{opposite}{hypotenuse} = \frac{b}{22}\\\\b = 22 \times sin 60 = 19.05[/tex]

[tex]22^2 = a^2 + b^2 \\484 = a^2 + 19.05^2\\a^2 = 484 - 362.9025\\a^2 = 121.0975\\a = \sqrt{121.0975} = 11.004[/tex]

( 3x - 12 / 9x^2 ) ÷ ( x - 4 / 3x ) =

( 3x - 12 / 9x^2 ) × ( 3x / x - 4 ) =

( 3 ( x - 4 ) / 3 × 3x × x ) × ( 3x / x - 4 ) =

( x - 4 / 3x × x ) × ( 3x / x - 4 ) =

( x - 4 ) × 3x / ( x - 4 ) × 3x × x =

1 / x

Thus the correct answer is option A .

Answer:

HCFD

Step-by-step explanation:

a² + b² = c² => a² = c² - b² => a = √(c² - b²)

=> the height of the window = √[(the given length of the latter)² - (the distance from the latter to the base of the building, 3.5 meters)²]

A) √(5.5² - 3.5²) ≈ 4.24 => H

B) √(8.8² - 3.5²) ≈ 8.07 => C

C) √(9.3² - 3.5²) ≈ 8.62 => F

D) √(7.9² - 3.5²) ≈ 7.08 => D

Answer:

2.36 inches

Step-by-step explanation:

V = 4.18879r³

to determine the value of r, make r the subject of the formula in the above equation

∛(V/4.18879) = R

∛(55/4.18879) = r

r = ∛13.130283

r = 2.36 inches

the hundredth is the second number after the decimal place. To convert to the nearest hundredth, look at the number after the hundredth (the thousandth). If the number is greater or equal to 5, add 1 to the hundredth figure. If this is not the case, add zero

y = 1/2x + x where x is any real number

y= -1/3 + x where x is any real number

Answer: to make a line parallel to y = 1/2x + 6, just change the y-intercept (6), and to make a perpendicular line to y = 3x - 8, turn the slope (3x) into its opposite (1/3x).

Answer:

[tex]x = - 16[/tex]

Step-by-step explanation:

Let's solve:

[tex] \frac{3}{4} x = - 12[/tex]

Step 1: Multiply both sides by 4/3.

[tex]( \frac{4}{3} )*( \frac{3}{4} x)=( \frac{4}{3} )*(−12)[/tex]

[tex]x = - 16[/tex]

[tex] \frac{3}{4} x = - 12 \\ \\ = > 3x = - 12 \times 4 \\ \\ = > x = \frac{ \cancel{- 12} \times 4}{ \cancel3} \\ \\ = > x = - 4 \times 4 \\ \\ = > x = 16[/tex]

Answer: 0.39 inch  snow fell on Wednesday than on Thursday.

Step-by-step explanation:

We are given that, It snows 0.7 inch on Wednesday and 0.31 inch on Thursday.

According to this model,

more snow fell on Wdifferenceednesday than on Thursday because 0.7 > 0.31

To compute the difference we subtract the length of snow on Thursday from length of snow on Wednesday.

Difference = 0.7-0.31

= 0.39 inch

Hence, 0.39 inch  snow fell on Wednesday than on Thursday.

Answer:

c 1602

Step-by-step explanation:

there are 36 months in 3 years but he pays every 4 months so now we do 36/4 to get 9 after we do 178x9 to get 1602

Answer:

x = 10

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides of the equation:

x - 4 (+4) = 6 (+4)

x = 6 + 4

x = 10

x = 10 is your answer.

~

You get this result after adding 4 to both sides. This is to undo the "minus 4" happening to the x.

To check the answer, replace x with 10 and simplify each side like so

x-4 = 6

10-4 = 6

6 = 6

We get the same thing on both sides, so that confirms the solution.

Given:

A segment has endpoints V and X.

To find:

The two names for the segment.

Solution:

A line segment is a small part of a line and it has two end points. The name of a segment is described by its end points.

For example: If A and B are two and points of a line segment, then the names for the segment are [tex]\overline {AB}[/tex] and [tex]\overline {BA}[/tex].

It is given that the segment has endpoints V and X.

Therefore, the two names for the segment are [tex]\overline {VX}[/tex] and [tex]\overline {XV}[/tex].

Answer:

I think it's C because it's a whole number while the others are fractions or decimals

Step-by-step explanation:

Answer:

54

Step-by-step explanation:

135(.6) = 81

total = 135

won = 81

lost = 54

OR you could just multiply 135 by 110%-60%, which is 40% or 0.4

135(.4) = 54
