Answer:

0.000002

Step-by-step explanation:

since its -6+2 you need to move the decimal place in 2, 6 places foward. So the number would go from 2 to 0.000002.

Unit rate!

Step-by-step explanation:

A unit rate is a rate that has a denominator of 1!

~ LadyBrain

Answer:

First, we can find the least common denominator for 8 and 3 which is 24.

5/8 = 15/24

1/3 = 8/24  

Then we can divide 15/24 by 8/24 which is 2 1/4.

If we then do 16 divided by 2 1/4 we get 7 1/9

Answer = 7 1/9

Answer:

A u B = {1,3,5,7,9,11,13,15,17,19,23}

A n B = {5,7,11,13}

Step-by-step explanation:

The prime numbers between 4 and 25 are; 5, 7, 11 , 13 , 17 , 19 and 23

A = {5, 7,11, 13, 17, 19,23}

B are odd numbers less than 16

B = {1, 3 , 5,7,9,11,13,15}

The union of both is the list of all values present in both sets without repeating;

A u B = {1, 3, 5,7,9,11,13,15,17,19,23}

A n B is the set that contains values that are present in both sets

A n B = {5,7,11 , 13}

Answer:

To get C

180-163(angles on a straight line)

=17

17 is vertically opposite c

And from geometry... Vertically Opposite angles are equal.

a=90°

b=163° too (Vertically opposite angles)

e=70(vertically opp. angles)

d=110.

Answer:

y = 4x - 7 (Answer C)

Step-by-step explanation:

First find the slope of this line.  Note that as we go from (2, 1) to (3, 5), x (the 'run') increases by 1 and y (the 'rise') increases by 4.  

Thus, the slope, m, is

m = rise / run = 4/1, or m = 4.

Apply the point-slope form of the equation of a straight line, since we now have both the slope and two points on the line:

y - k = m(x - h) becomes y - 1 = 4(x - 2)

Solving for y, we get:  y = 4x - 8 + 1, or y = 4x - 7 (Answer C)

Step-by-step explanation:

f(x) = 2^x (this is exponential function)

f(x) = 8

the equation is :

2^x = 8

2^x = 2³

cross out 2

so, we get : x= 3

The conversion is given below.

x is 3.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = [tex]2^x[/tex]

f(x) = strength and x is the length.

Now,

Strength = 8

So,

8 = [tex]2^x[/tex]

Taking logs on both sides.

log 8 = x log 2

x = log 8 / log 2

x = log (8/2)

x = log 4

x = log [tex]2^2[/tex]

x = 2 log 2

or

2 x 2 x 2 = 2³ = 8

So,

8 = 2³

x = 3

Thus,

x = 3.

Answer:

785

Step-by-step explanation:

did the math in a calculator I got yoy

Answer:

D. 785

Step-by-step explanation:

the formula to find the surface area of a cylinder is A=2πrh+2πr^2

the diameter is a straight line through the center of a figure so half of that would be the radius and our diameter is 10 so the radius is 5

our height is 20 so now we put it into the equation it will look like this

2·π·5·20+2·π·5^2

[tex]10^4\\\\10*10*10*10\\\\100*100\\\\10000\\\\\\10000*6.16\\\\61600[/tex]

Answer:

Step-by-step explanation:

we know that the triangle to the center is an isosceles,  so the two angle on the circle of that triangle are the same.   both 41,  so 41*2 =82  

all the way around that isosceles triangle is 180  so

180-82 = 98

the angle at O is 98°

the arc BC spans 98°

angle 'a'  is 1/2(98°)

a = 49°

X = 29

Answer:

Step-by-step explanation:

The mean is calculated as

mean = [tex]\frac{sum}{count}[/tex]

let x be the score required to give a mean of 27 in the 6 games

[tex]\frac{38+27+23+19+26+x}{6}[/tex] = 27 ( multiply both sides by 6 )

133 + x = 162 ( subtract 133 from both sides )

x = 29

Step-by-step explanation:

Answer:   I think it's D

Step-by-step explanation: I say the answer is (B) because  in the full question, it's asking how much would 2.5 means, therefore, you're multiplying, to get 125.

If 1cm=50km Then 2.5 is 50km, 50km, 25

50+50+25=125, or simply just multiply. 25 is half of 50, so with the 2.5 there, doesn't make it a whole number, therefore, making the 25 in it's place, because of the 2.5.

Answer:

Supplementary angles.

Step-by-step explanation:

We can define two big groups of pairs of angles.

Complementary and supplementary angles.

Two angles are complementary if the sum of their measures is equal to 90°

Two angles are supplementary if the sum of their measures is equal to 180°

Here, we have the angles 160° and 20°, and we know that their sum is 180°

Then we can conclude that the given angles fall in the group of the supplementary angles.
