Step-by-step explanation:
Hope this helps
Answer:
80 mStep-by-step explanation:
The described points form two right triangles which share same horizontal leg a.
The bottom triangle has 60 m vertical length and 60° opposite angle.
The triangle on the top has unknown (x) vertical length and 30° opposite angle.
We are looking for the distance x + 60 m
On the top triangle we have:
tan 30° = x/a ⇒ a = tan 30° / xOn the bottom triangle we have:
tan 60° = 60/a ⇒ a = tan 60° / 60Comparing we get:
tan 30° / x = tan 60° / 60 x = 60 tan 30° / tan 60°x = 20 mSo the distance is:
60 m + 20 m = 80 mGiven the coordinates of a rectangle A(2,5) B(6,5) C(6,-5) and D(2,-5), write the equations of the lines of reflection

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

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.
Irena sells ice cream
One day she sells 80 ice creams,
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%
Answer:
The answer is 35%.

The height of a rectangular prism is 15 centimeters the area of its base is 270 square centimeters
What is the volume of the rectangular prism?
Answer:4,050
Step-by-step explanation:
The volume of the rectangular prism is 4050 centimeter cube
What is Volume?Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.
What is rectangular prism?In geometry, a rectangular prism can be defined as a 3-dimensional solid shape which has six faces that are rectangles
Height of the rectangular prism =15 cm
Area of the base =270 centimeter square
Volume of the rectangular prism = Area of the base × Height
=270×15
=4050 centimeter cube
Hence, the volume of the rectangular prism is 4050 centimeter cube

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

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.
When you reflect a point over the x-axis you negate the y value.

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.
