Explain how to use ratio tables and compare ratios.
Answer:
You should ALWAYS do everything by the same value for using the tables Step-by-step explanation:
if one side gets multiplied so should the other, so let's say you had 2:4 if you are multiplying the 4 by 3, you should also multiply the 2 by 3.
Comparing ratios:
In order to compare a ratio you must have a number that is constant, basically in other words a common number. A number that almost is always the multiplied, or divided by the same amount.

A card is drawn at random from a standard pack of 52 playing cards find the probity of drawing a heart or a club
Answer:
1/2
Step-by-step explanation:
From the question, there are 13 cards of heart and 13 card of club in each suit in each deck.
P(drawing heart) = 13/52
P(drawing club) = 13/52
And we know total standard pack =52
P(drawing a heart or a club)
= number of favourable outcome/ total Number of outcome
P( drawing heart or club) =( 13+13)/52
=26/52
=1/2
Can you find the slope and type the correct code?
Answer:
1. (3,19) and (-1,-13)
to find the slope you need to do [tex]\frac{y2-y1}{x2-x1}[/tex]
Hence [tex]\frac{-13-19}{-1-3}[/tex]= 32/-4=-8
2. Take two points on the graph:
(-2,3) and (1,0)
Know that to calculate the slope you do
[tex]\frac{rise}{run}[/tex]= 4/2= 2
3. To find the slope in a table you need to choose any two points and utilize the following formula: [tex]\frac{y2-y1}{x2-x1}[/tex]= [tex]\frac{-16-(-8)}{2-1}[/tex]=-8/1= -8
4. Like in #1 we take the two points and plug it into the formula:
[tex]\frac{8-(-10)}{0-9}[/tex]=18/-9= -2

Which expression is equivalent to 20c-8d? Show all work and circle letter of correct answer.
2(10c+4d)
4(5c-8d)
4(5c-2d)
c(20-8d)
Answer correctly and get brainiest
Answer: This one is equal to what we were looking for.
4 × 5c = 20 - 8d = 12
Step-by-step explanation:
(20c - 8d = 12) so we are look for an expression that is equal to 20c 8d and 12
2 × 10c = 20 + 4d = 24
4 × 5c = 20 - 8d = 12
4 × 5c = 20 - 2d = 18
c20 - 8d = 12

Is (x+1)/x^2 greater or less or equal to 1/x
Answer:
(1) x^2 is greater than 1.
(2) x is greater than -1.
(1) x^2 is greater than 1 --> x2>1x2>1 --> x<−1x<−1 or x>1x>1. Sufficient.
(2) x is greater than -1 --> x>−1x>−1. Not sufficient.
Lin bought x grams of sugar. Jada bought 3⁄4 more than that. Select all equations that represent the relationship between the amount of sugar that Lin bought, x, and the amount of sugar that Jada bought, y.
Answer:
y = 7/4xStep-by-step explanation:
Lin bought x grams of sugar.
Jada bought 3⁄4 more than Lin bought.
The equation:
y = x + 3/4x ⇒ y = 7/4xFor students majoring in Hospitality Management, it was determined that 5% have visited 1–10 states, 16% have visited 11–20 states, 45% have visited 21–30 states, 19% have visited 31–40 states, and 15% have visited 41–50 states. Suppose a Hospitality Management student is randomly picked. What is the probability that the student has visited 30 or fewer states?
9514 1404 393
Answer:
66%
Step-by-step explanation:
The categories are mutually exclusive, so we have ...
P(≤30) = P(1–10) +P(10–20) +P(20–30) = 5% +16% +45%
P(≤30) = 66%
The probability is 66% that a randomly chosen student has visited 30 or fewer states.

The X coordinate of a point P on X axis is 4 and the y coordinate of a point Q on y axis is 3. Find the distance of PQ.
Answer:
5 units
Step-by-step explanation:
Since The X coordinate of a point P on X axis is 4 and the y coordinate of a point Q on y axis is 3 the points are
P (4 , 0) and Q(0 , 3)
The formula to calculate distance between two points
[tex]PQ=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\PQ=\sqrt{(0-4)^2+(3-0)}\\PQ=\sqrt{(4)^2+(3)^2}\\PQ=\sqrt{16+9} \\PQ=\sqrt{25} \\PQ=5\ units\ \\[/tex]
IMPORTANT!
As we take the square root of 25 we get two values +5 and -5 we always take the positive value because distance can never be negative.

How many sides does the polygon measures 160 degrees how many sides does the polygon have???
Answer:
18 sides
Step-by-step explanation:
I'm not sure what the question is, but this is what I think the question is.
"An interior angle of a regular polygon measures 160 degrees. How many sides does the polygon have?"
The sum of the measures of the interior angles of a polygon of n sides is
(n - 2)180
If the polygon is a regular polygon, then the measure of each interior angle is
(n - 2)180/n
Here, we are told an interior angle measures 160 deg.
(n - 2)180/n = 160
(n - 2)180 = 160n
(n - 2)18 = 16n
(n - 2)9 = 8n
9n - 18 = 8n
n = 18
Answer: 18 sides

Which value is equivalent to 9^c x 9^-c A. 0 B. 1 C. 1/9^2C D. 9
Answer:
B
Step-by-step explanation:
Using the rule of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex]
[tex]a^{0}[/tex] = 1
Given
[tex]9^{c}[/tex] × [tex]9^{-c}[/tex]

Multiple choice question: A square mosaic is made of small glass squares. If there are 196 small squares
in the mosaic, how many are along one edge? Image is of a mosaic, not the
problem. *
O 14 squares
O 49 squares
O 98 squares
O 16 squares
Answer:
14 squares
Step-by-step explanation:
1. We know if the mosaic is a square shape, all sides are the same length and consist of the same amount of squares
2. Area is L×W, so in this case A×A=196
3. We can test this by replacing A with 14 and seeing if the answer is correct.
4. 14×14=196 is true
This can also be done by finding the square root of 196.
What is the sign of the product (8)(−23)( −21)(−29)?
A) Positive, because the products (8)(−23) and (−21)(−29) are negative, and the product of two negative numbers is positive
B)Positive, because the products (8)(−23) and (−21)(−29) are positive, and the product of two positive numbers is positive
C)Negative, because the product (8)(−23) is positive and the product (−21)(−29) is negative, and the product of a positive number and a negative number is negative
D)Negative, because the product (8)(−23) is negative and the product (−21)( −29) is positive, and the product of a negative number and a positive number is a negative number
Answer:
D) Negative, because the product(8)(-23) is negative and the product of (-21)(-29) is positive, and the product of a negative number and a positive number is negative number
Buddy painted (1/5) of the 320 nutcrackers.How many nutcrackers did buddy paint
Answer:
64
Step-by-step explanation:
Given that,
Buddy painted (1/5) of the 320 nutcrackers.
We need to find how many nutcrackers did buddy paint. It can be calculated by finding (1/5) of 320.
[tex]x=\dfrac{1}{5}\times 320\\\\=64[/tex]
Hence, he painted 64 nutcrackers.
