Five years ago, Julie was 4 feet 7 inches tall. Her sister Carrie was 5 feet 1
tall. Since then, Carrie has grown 2 inches each year. Julie grew 13 inches
during the last 5 years. How much taller than Julie is Carrie now?
The differnce in the height of Carrie and Julie given their rate of growth is 3 inches.
What is the difference in height?Carrie's height = 5 feet 1 inch + (2 x 5)
= 5 feet 1 inch + 10 inches
5 feet 11 inches
Julie's height = 4 feet 7 inches + 13 inches
4 feet 20 inches
Difference in height = 5 feet 11 inches - 4 feet 20 inches
I feet = 12 inches
71 inches - 68 inches
3 inches

Identify the graphed linear equation.
A: y=2x +2
B: y=2x +3
C: y=3x +2
D: y=3x +3
Answer:
B: y = 2x + 3

The 2x is the slope, and the 3 is the y-intercept
The y-intercept is kinda like how far the slope is from zero, but it can only be applied to the y-axis.
The slope is... well... the slope-- like how steep it is. If a slope is 2/1, like in the graph, it will go higher 2 units every 1 unit across. Or, if the slope is 1/4: The slope will go 1 unit higher every 4 units

Answer
hours
Answer:
What we know:
39 hours is the total amount of time spent on the trip.14 hours spent with both walking and the train.Our challenge:
To figure out how many __ hours were spent on the bus.Let's set up an equation,
-we'll assume that 'x' are the unknown hours spent on the bus.
The unknown hours spent on the bus plus the hours spent both on walking/and the train will equal a total of 39 hours.
So,
14 + x = 39
Solve for x;
-14 -14
x = 25, the hours Jerry spent riding on the bus is 25 hours.
Answer:
25 hours

A line passes through the point (-8,5) and has a slope of -3/4 .
Write an equation in slope-intercept form for this line.
Answer:
Step-by-step explanation:
Formula
The basic formula is
y = mx + b
m = the slope
b = the y intercept
What you know so far
y = mx + b.
You know that the slope = -3/4
y = - 3/4 x + b
y intercept
The point is used to find the y intercept.
x = - 8
y = 5
Subtitute these two values into the equation above.
5 = -3/4 * (-8) + b Multiply the factors on the right
5 = 6 + b Subtract 6 from both sides
5 - 6 = b Combine
-1 = b
Answer: y = -(3/4) x - 1
Answer:
[tex]\Longrightarrow:\boxed{\sf{y=-\dfrac{3}{4}x-1}}[/tex]
Step-by-step explanation:
Use the slope-intercept form.
Slope-intercept form:
[tex]\Longrightarrow: \sf{y=mx+b}[/tex]
The m represents the slope.The b represents the y-intercept.X= (-8)
Y= 5
[tex]\sf{5=-\dfrac{3}{4}*(-8)+b}[/tex]
5=6+b
Subtract the sign.
5-6=b
Solve.
Isolate the term of b from one side of the equation.
Subtract the numbers from left to right.
⇒ 5-6=-1
⇒ -1=b
Change the equation.
⇒ b=-1
So, therefore, the y-intercept is -1.
[tex]\Longrightarrow: \boxed{\sf{y=-\dfrac{3}{4}x-1}}[/tex]
Therefore, the correct answer is y=-3/4x-1.I hope this helps! Let me know if you have any questions.

The measure of the unknown angle in the triangle is 58 degrees.
What is a triangle ?A triangle has three sides and the sum of the angles of a triangle is 180 degrees.
Triangles can be classified base on there angles and length of the sides.
Therefore,
let the length of the unknown angle = x
x + 65° + 57° = 180°
x + 122 = 180
subtract 122 from both sides
x + 122 - 122 = 180 - 122

Find the volume of a pyramid with a square base, where the perimeter of the base is 14 m and the height of the pyramid is 8.8 m. Round your answer to the nearest tenth of a cubic meter.
The volume of the pyramid with a square base, where the perimeter of the base is 14 m and the height of the pyramid is 8.8 m is 35.9 m³
How do i determine the volume of the pyramid?First, we shall determine the determine the area of the square base. This is shown below:
Perimeter of square (P) = 14 mArea of the square base (A) = ?P = 4L
14 = 4L
Divide both sides by 4
L = 14 / 4
L = 3.5 m
Now, the area is obtained as follow
A = L²
A = 3.5²
A = 12.25 m²
Finally, we shall determine the volume of the pyramid. Details below:
Area of the square base (A) = 12.25 m²Height of pyramid (h) = 8.8 mVolume of pyramid (V) = ?V = ⅓Ah
V = ⅓ × 12.25 × 8.8
V = 35.9 m³
Thus, we can conclude that the volume of the pyramid is 35.9 m³

Answer:
Below.
Step-by-step explanation:
To find the volume of the silo find the volum of the hemisphere with radius of 15 feet and add the volume of the cylinder with a radius of 15 feet and a height of (100 - 15) = 85 feet.
The total volume = 1/2 * 4/3 π (15)^3 + π (15)^2 * 85
= 67151.5 ft^3.
Step-by-step explanation:
find the volume of a sphere with a radius of 15 ft and divide by 2 (because there is only half a sphere on top of the silo).
then add the volume of a cylinder with a radius of 15 ft and a height of 85 ft (because we need to deduct the radius of the sphere from the total height to get the height of the cylinder itself).
