Answer:
a. 3 : 2
b. 2 : 15
c. 3 : 2
Step-by-step explanation:
Red fish = 3
Yellow fish = 6
White fish = 4
Black fish = 2
Total number of fishes = 15
a) Ratio of the Number of yellow fish to the number of white fish.
Yellow fish : White fish
6 : 4
= 6 /4
= 3/2
= 3 : 2
Ratio of the Number of yellow fish to the number of white fish = 3 : 2
b) Ratio of the Number of black fish to the total number of fish
Black fish : Total fish
2 : 15
= 2 / 15
= 2 : 15
Ratio of the Number of black fish to the total number of fish = 2 : 15
c) Ratio of the Number of red fish to the number of black fish
Red fish : black fish
= 3 : 2
= 3/2
= 3 : 2
Ratio of the Number of red fish to the number of black fish = 3 : 2

Answer:
second choice y = -2(x+4) + 15
When you reflect a point over the x-axis you negate the y value.
True
False
Answer:
True.
Step-by-step explanation:
The rule for reflecting the X value is to negate the Y value but leave the X as it is.
Example: K= (7,2) when reflected it would be (7,-2).
The population in Smalltown in 2010 was 45,230 people and is growing exponentially at a
rate of 2%. What will the population be in 2030?
O 67,475
O 81.928
O 67.209
O 82.414
Answer:
The first option
67475
Step-by-step explanation:
Step one:
Given data
The population in Smalltown in 2010 was 45,230
rate= 2%= 0.02
time t= 20 years
Step two:
Let P(t) = population t years after 2010
= 45230e^0.02t
Population in 2030 = P(20)
= 45230e^0.02t(20)
= 45230e^0.4
≈ 67475

Answer:
Answer is D
Step-by-step explanation:
0x means that the x axis did move. the y intercept is 1.5. if no number appears infront of y or x just know that the 1 is always infront of y or x even if you don't see it.

7x-7=3x-23. can u show the steps
Answer: ight bet i gotchu its x=−4
Step-by-step explanation:
Let's solve your equation step-by-step.
7x−7=3x−23
Step 1: Subtract 3x from both sides.
7x−7−3x=3x−23−3x
4x−7=−23
Step 2: Add 7 to both sides.
4x−7+7=−23+7
4x=−16
Step 3: Divide both sides by 4.
4x/4=-16/4

Santa has many toys to deliver on Elm Street. If there are 48 kids that live on Elm
Street and 12 of them are boys what is the ratio of girls to boys?
Answer: 3 : 1
Step-by-step explanation:
We know that there are 48 kids in Elm street.
12 of them are boys, then the number of girls will be:
48 - 12 = 36
So there are 12 boys and 36 girls.
Then the ratio of girls to boys is 36:12
We can divide both numbers by the same number and we will get an equivalent ratio, if we divide by 12 in both sides, we have:
36/12 : 12/12
3 : 1
Then the ratio is 3 to 1.

The graph shows the proportional relationship between rainfall during the growing season and seasonal growth of a type of plant. What does the point (8,6) represent? If the plants grew 12 mm one season, how much rain fell?
Answer/Step-by-step explanation:
✔️The point (8, 6) represents seasonal plant growth of 6 mm with 8 cm of rainfall during the growing season.
✔️To determine how much rain fell if the plants grew 12 mm one season, find the value of x (rainfall) when y (plant growth) = 12.
From the graph, when y = 12, x = 16.
This means that when the plant grew 12 mm, 16 cm of rainfall was recorded.
Therefore:
If the plants grew 12 mm one season, 16 cm rainfall fell.

If \triangle △RST is isosceles. find x then find m∠S.
due in 30 min plz help
X=
m∠S =
Answer:
s=32
Step-by-step explanation:
15x-31 = 9x+11
6x=42
x=7
2(63+11)= 2(74)= 148
180-148=32
Isosceles triangles have equal base angles.
The values of x and S are 7 and 32, respectively.
The base angles are given as: 15x - 31 and 9x + 11
So, we have:
[tex]\mathbf{15x - 31 = 9x + 11}[/tex]
Collect like terms
[tex]\mathbf{15x - 9x =31+ 11}[/tex]
[tex]\mathbf{6x =42}[/tex]
Divide both sides by 6
[tex]\mathbf{x =7}[/tex]
The measure of S is:
[tex]\mathbf{S = 180 - (15x - 31) - (9x + 11)}[/tex]
Substitute 7 for x
[tex]\mathbf{S = 180 - (15\times 7 - 31) - (9\times 7 + 11)}[/tex]
[tex]\mathbf{S = 180 - (74) - (74)}[/tex]
[tex]\mathbf{S = 32}[/tex]
Hence, the values of x and S are 7 and 32, respectively.

the next day she sells 108 ice creams.
Work out the percentage increase in the number of ice creams she sells.
Answer:
35%
Step-by-step explanation:
Change/original x 100
The change between 80 and 108 is 108-80 = 28.
28/80 x 100 (80 is our original number of ice cream cones that she sold).
.35 x 100 = 35%
