Answer:

7/20

Step-by-step explanation:

9/40, 9 divided by 40 is 0.225. 1/8, 1 divided by 8 is 0.125. Add 0.225 and 0.125 you get 0.35. 35% (0.35) of 100 to a fraction is 7/20. 7 divided by 2 is 3.5 or 0.35, 20 divided by 2 is 10 or 1. So yeah. Hope This Helps :)

you do this 8 x 6 x 14 x 4 = 672

Answer:

29

Step-by-step explanation:

In a triangle, a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

Given this formula, we knoe c^2 is the product of 21^2 + 20^2.

This gives you 841. Now you just find the square root of 841 which is 29.

Hope this helps :)

Answer:

3×6=18 t= (6)

I hope this helps by using division

Answer:

t = 6

Step-by-step explanation:

you want (t) by itself so you would divide both sides by -3. A negative divided by a negative is a positive. same goes for multiplying two negative numbers. The answer would be positive

Answer:

linear.

rotary.

reciprocating.

oscillating.

Answer:

m∠ABC = 42°

Step-by-step explanation:

5x + 13 + 3x + 33 = 70

8x + 46 = 70

8x = 24

x = 3

m∠ABC = 3(3) + 33 = 42

Answer:

$1505

Step-by-step explanation:

area = 5 x 7 = 35 m²

35 m² x $43 per m² = $1505

Answer: 35

Step-by-step explanation:

Answer:

-24a^10

Step-by-step explanation:

Given the equation −4a^5⋅6a^5

This can also be written as

−4a5⋅6a^5

= (-4*6)(a^5*a^5)

= -24(a^{5+5})

= -24a^10

Hence the required expression is -24a^10

Answer:

37.68 inches

Step-by-step explanation:

The formula for the circumference of a circle is 2πr.

The radius is 6, and 6⋅2 = 12 (diameter).

3.14 = pi.

12 ⋅ 3.14 = 37.68

Whichever answer is closest to 37.68 is your answer!

Answer:

C. It is likely

Step-by-step explanation:

Given

For the square.

Let

[tex]Length = L[/tex]

So, the area is:

[tex]Area = Length^2[/tex]

[tex]A_1=L^2[/tex]

The side length of the square equals the diameter of the circle.

So:

[tex]diameter (d) = L[/tex]

The radius is:

[tex]r = \frac{1}{2}d[/tex]

[tex]r = \frac{1}{2}L[/tex]

The area is:

[tex]Area = \pi r^2[/tex]

[tex]A_2 = \pi * (\frac{1}{2}L)^2[/tex]

[tex]A_2 = \pi * \frac{1}{4}L^2[/tex]

[tex]A_2 = \frac{22}{7} * \frac{1}{4}L^2[/tex]

[tex]A_2 = \frac{22}{28} L^2[/tex]

The likelihood that a point will be common to the square and the circle is:

[tex]Pr = \frac{A_2}{A_1}[/tex]

[tex]Pr = \frac{\frac{22}{28} L^2}{L^2}[/tex]

[tex]Pr = \frac{22}{28}[/tex]

[tex]Pr = 78.57\%[/tex]

The above probability is greater than 50% but less than 100%.

Hence, it is likely

Answer:

C. Likely

Step-by-step explanation:

all the points are in the circle so it's likely to choose a point inside the circle

Answer:

[tex]7x ^ 5 - x ^ 3- x ^ 2 + 4x[/tex]

Step-by-step explanation:

1) [tex]3x ^ 4 + 2x ^ 3 - 5x ^ 2 + 4x ^ 2 + 6x - 2x - 3x ^ 4 + 7x ^ 5 - 3x ^ 3[/tex]

Rearrange the expression.

2) [tex]7x ^ 5+3x ^ 4- 3x ^ 4 + 2x ^ 3 - 3x ^ 3- 5x ^ 2 + 4x ^ 2 + 6x - 2x[/tex]

Solve.

3) [tex]7x ^ 5 - x ^ 3- x ^ 2 + 4x[/tex]

Answer:

2/3

Step-by-step explanation:

All you do is find the reciprocal,

you take the equation, flip, then change the sign of the numerator. so,

In this it's already done, the sign on top is already changed and so is the equation fliped so we do the opposite,

which would give you 2/3 because the perpendicular line of 2/3 is -3/2 which makes them perpendicular to each other and there is your answer.

Answer:

y = -x - 6

Step-by-step explanation:

If it's parallel, then it means that the slope will remain the same. The slope is

-1.

To find the y-intercept, you need to plug the coordinates into the equation,

y = -1x + b

-3 = -1(-3) + b

-3 = 3 +b

-6 = b

The equation is y = -x - 6

Answer:

3. D) 26, 7, 31

4. B) 6, 34, 27

Step-by-step explanation:

Both #3 and #4 use the same strategy: the two shorter sides' sum has to be greater than the longer side.

#3:

2 + 8 is 10, which is less than 13. So A wouldn't form a triangle.

12 + 22 is 34, which is the length of the longer side. So B wouldn't form a triangle either.

14 + 18 is 32, which is less than 40. So C wouldn't form a triangle.

7 + 26 is 33, which is greater than 31. So D would form a triangle.

D. 26, 7, and 31 are the only lengths of the ones shown that form a triangle.

#4:

17 + 18 is 35, which is greater than 19. So A would form a triangle.

11 + 22 is 33, which is greater than 25. So C would also form a triangle.

5 + 18 is 23, which is greater than 20. So D would form a triangle.

6 + 27 is 33, which is less than 34. So B wouldn't form a triangle.

B. 6, 34, and 27 are the only lengths of the ones shown that don't form a triangle.
