Answer:

2/13    or  15.38%

Step-by-step explanation:

Number of Aces in a deck = 4

Number of 7s in a deck = 4

Number of cards in a deck = 52

Probability of A or 7 = (4 Aces + 4 Sevens) / 52 cards                                          8 cards / 52 cards

This simplifies to                           2/13    or  15.38%

D.the population change is inconsistent

Answer:

The slope of the line is: M = 0

Step-by-step explanation:

Using the "Slope from 2 points" formula which is \/

M = (y2 - y1) / (x2 - x1)

We just need to input the numbers to find the slope!
M = ( 1 - 1 ) / (1 - - 2 )

Now solve within the parentheses:

M = ( 0 ) / ( 3 )

Which is basically just 0.

I hope the formula: M = ( y2 - y1) / (x2 - x1)

Answer:

s < 50

Step-by-step explanation:

This is an inequality that can be used to express the amount of flowers planted. If Jones planted s flowers, Kerry planted 50, and Jones planted less flowers than Kerry, s must be less than 50.

Using Pythagoras theorem:-

H²= P²+ B²

Putting the value in equation

[tex] {x}^{2} = {5}^{2} + {3}^{2} \\ {x}^{2} = 25 + 9 \\ {x}^{2} = 34 \\ x = \sqrt{34} = 5.83[/tex]

Volume of a cone is:

V = 1/3pi•r^2•h

Fill in the given information.

847.8

= 1/3(3.14)9^2•h

847.8 = 84.78h

divide by 84.78

10 = h

The measure of angle HIJ is 20°. The correct option is the last option 20°

From the question, we are to determine the measure of angle HIJ

From one of the Circle theorems, we have that

The angle at the center of a circle is twice the angle at any part of the circumference

From the information,

The measure of arc HJ is 40°. That is, the angle at the center is 40°.

Then, using the above theorem,

Measure of angle HIJ = 40° / 2

Measure of angle HIJ = 20°

Hence, the measure of angle HIJ is 20°. The correct option is the last option 20°

The slope of the line that passes through the points (0, -4) and (30, -9) is -1/6

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=(y₂-y₁)/(x₂-x₁)

x₁=0, y₁=-4, x₂=30, y₂=-9

Substitute in slope formula

m=(-9-(-4))/(30-0)

m=-9+4/30

m=-5/30

m=-1/6

Hence the slope of the line that passes through the points (0, -4) and (30, -9) is -1/6

Answer:

6 units

Step-by-step explanation:

since the y- coordinates of both points are 7 then the horizontal distance between the points is the absolute value of the difference in the x- coordinates , that is

d = | 9 - 3 | = | 6 | = 6 units , or

d = | 3 - 9 | = | - 6 | = 6 units

Answer:

9000 ft

Step-by-step explanation:

Given: A airplane is ascending at a constant rate of 15 feet per second,

What we need to know: The change in altitude during 10 minutes of flight,

60 seconds = 1 minute

60 × 10

= 600 seconds

600 × 15

= 9000 ft

Therefore there was a 9000 ft change in altitude during the 10 minutes of the flight.

Answer:

M+16m

Step-by-step explanation:

-9m+9 cancel eachother out because it is a negative and a postive value, so you would just put the variable. For 8m+8 it would be 16m because the sre both positive so you would add them like normal

Step-by-step explanation:

[tex] = ( - 9m + 9) + (8m + 8)[/tex]

[tex] = - 9m + 9 + 8m + 8[/tex]

[tex] = - 9m + 8m + 9 + 8[/tex]

= m + 17

hence m + 17 is the answer....

Answer:

36

Step-by-step explanation:

A ratio 4:6 means the one quantity is 4/10 of the full thing:

While the other quantity is 6/10 of the full thing

So the smaller angle will be 4/10 of the the complementary angle.

Complementary angle is 90.

So 4/10 of 90 is 36.
