Steps to solve:
5(y + 2/5) = -13
~Distributive Property
(5 * y) + (5 * 2/5) = -13
~Simplify
5y + 2 = -13
~Subtract 2 to both sides
5y + 2 - 2 = -13 - 2
~Simplify
5y = -15
~Divide 5 to both sides
5y/5 = -15/5
~Simplify
y = -3

The value of expression 1/10.
Given that we need to solve expression 100% - 9/10,
To explain the calculation of "100% - 9/10," let's break it down step by step:
First, let's simplify the fraction 9/10. This fraction represents a ratio where the numerator (9) is the number of parts, and the denominator (10) is the total number of parts.
In this case, it means that we have 9 parts out of a total of 10 parts.
Next, we need to calculate the percentage equivalent of 9/10. To do this, we can multiply the fraction by 100.
So, 9/10 × 100 = 90%.
This means that 9/10 is equivalent to 90%.
Finally, we subtract 90% from 100%. Since 100% represents the whole or the entirety, subtracting 90% from it gives us the remaining percentage.
Mathematically, 100% - 90% = 10%
10% = 1/10
Therefore, 100% - 9/10 equals 10%.

What is the surface area of the cone? Express your answer in terms of π.b
Given:
Radius of the cone = 5 ft
Slant height of the cone = 21 ft
To find:
The surface area of the cone
Solution:
Surface area of cone formula:
[tex]SA=\pi r^{2}+\pi r l[/tex]
where r is the radius and l is the slant height.
[tex]SA=\pi \times 5^{2}+\pi \times 5 \times 21[/tex]
[tex]SA=\pi \times 25+\pi \times 105[/tex]
[tex]SA=25 \pi+ 105 \pi[/tex]
[tex]SA=130 \pi[/tex]
The surface area of the cone is 130π square feet.
The total surface area of the cone is 130π square feet.
How to Calculate the Surface Area of a Cone
The surface area of a cone can be calculated using two main components: the base and the lateral (side) surface. If the radius of the base is r and the slant height is l, the formulas for these areas become essential.
The area of the base is found using the formula for the area of a circle: πr².The lateral surface area is calculated using: πrl, where l is the slant height.Therefore, the total surface area A of the cone is:
A = πr² + πrl
Calculate the surface area using the given values:

A race begins with 2 1/2 miles through town, continues through the park for 2 1/3 miles, and finishes at the track after the last 1/6 mile. A volunteer is stationed every quarter mile and at the finish line to pass out cups of water and cheer on the runners. How many volunteers are needed?
Answer:
You would need 20 volunteers
Step-by-step explanation:
If you make all of the fractions have a denominator of 6 then they would all add up to 1 which would be 2+2+1 which is 5 miles. Then you multiply 5 by 4 (for ever quarter mile) and it equals 20
Answer:20 I think
Step-by-step explanation:
So you add all the miles up 2 1/2 + 2 1/3 + 1/6 = 5 miles
A volunteer is stationed every quarter (1/4)
1 mile divided into 1/4 is 4
So 5 times 4 is 20

Final answer:
The correct ratio to compare the number of turkey sandwiches to vegetarian sandwiches is 3:1, with 18 students selecting turkey and 6 students selecting vegetarian sandwiches.
Explanation:
The correct ratio to compare the number of turkey sandwiches to the number of vegetarian sandwiches is 3:1.
First, determine that 18 students chose turkey sandwiches, which leaves 6 students choosing vegetarian sandwiches (24 total students - 18 turkey sandwiches).Next, calculate the ratio by dividing the number of turkey sandwiches by the number of vegetarian sandwiches, resulting in 18/6 = 3.Therefore, the ratio of turkey sandwiches to vegetarian sandwiches is 3:1.

Without diagrams, it's only possible to give general descriptions, suggesting various intersecting, parallel, or skew scenarios.
Explanation:Without diagrams or additional context, it's difficult to determine the relationships between the segments and planes, but I will provide general descriptions. Lines AB and BC appear to intersect if 'B' is the shared point between them. Lines AE and BF could be parallel, intersecting, or skew, depending on their orientation in space. Lines EF and AD again depend on their spatial orientation. Plane ABC and Plane ABF may intersect along line AB, if they are not the same plane. Plane AED and Plane BFC could also intersect, be parallel, or neither, depending on how the points are positioned in space.

What’s the length of the arc for a circle with a radius of 6 and a central angle of 48 degrees
Answer:
5.02655 units
Step-by-step explanation:
A circle consists of 360 degrees. Thus, 48 degrees is 48/360 of a circle. This relationship transfers to the arc length. The arc length with a central angle of 48 degrees is 48/360 of the entire circle's circumference. Thus:
[tex]Arc(Length) = \frac{48}{360}* 6*2*\pi = 5.02655[/tex]
A rectangular prism has a volume of 600 cubic inches.
If the height of the prism is 5 inches and the width is 10 inches,
what is the length of the prism? Enter your answer in the box.
Answer:
The length is 12 inches.
Step-by-step explanation:
The volume of a rectangular prism is given by:
V=LBH
It was given that; the rectangular prism has a volume of 600 cubic inches.
The height of the prism is 5 inches and the width is 10 inches.
We want to find the length of the rectangular prism.
We substitute V=600, H=5,and W=10 into the formula:
600=5×10×L
600=20L
[tex] L = \frac{600}{50} [/tex]
[tex]L = 12in[/tex]
The length of the rectangular prism is 12 inches.
To find the length of a rectangular prism, we can use the formula for volume:
Volume = Length × Width × Height
We know the volume is 600 cubic inches, the height is 5 inches, and the width is 10 inches. We can rearrange the formula to solve for the length:
Length = Volume / (Width × Height)
Substitute the known values into the equation:
Length = 600 / (10 × 5)
Length = 600 / 50
Length = 12 inches
Therefore, the length of the rectangular prism is 12 inches.
A marble was dropped into a graduated cylinder holding a volume of 20 mL. The water level increased to 35 mL. The mass of the marble is 37.8 grams. What is the density of the marble?
Answer:
2.52 g/ml
Step-by-step explanation:
Density is defined as the mass per unit volume of a substance. Therefore,
density, d=m/v
Where d denote density, m for mass and v for volume.
The volume of marble is given by getting the difference in the reading of graduated cylinder. Since the initial reading was 20 ml and final reading 35 ml, rhen the volume is 35-20=15 ml
The mass is given as 37.8 grams.
Density is therefore 37.8 g/15ml=2.52 g/ml
Density of marble is 2.52 g/ml
Final answer:
The density of the marble is calculated by dividing its mass (37.8 grams) by its volume (15 mL), leading to a density of 2.52 g/mL.
Explanation:
The density of an object can be found by dividing its mass by its volume. In this case, the mass of the marble is 37.8 grams, and when dropped into a graduated cylinder, the water level rose from 20 mL to 35 mL. The change in water level represents the volume of the marble, which is 15 mL (35 mL - 20 mL).
To find the density, perform the following calculation: density = mass/volume. Thus, the density of the marble = 37.8 grams / 15 mL = 2.52 g/mL.

The number line shows four elevations in Death Valley National Park.Enter the difference ,in feet between the elevation at Zabriskie Point and Furnace Creek.
Given:
The number of elevations in Death Valley National Park is given below:
Zabriskie Point = 648 feet
Stovepipe Wells = 0 feet
Furnace Creek = -178 feet
Badwater Basin = -282 feet
To find the difference between the elevation at Zabriskie Point and Furnace Creek.
Formula
Difference means subtraction.a-(-b) = a+bSo,
The difference between the elevation at Zabriskie Point and Furnace Creek = (648-(-178)) feet
= 648+178 feet
= 826 feet
Hence,
The difference between the elevation at Zabriskie Point and Furnace Creek is 826 feet.
The elevation difference between Zabriskie Point and Furnace Creek in Death Valley National Park is 826 feet, obtained by adding the positive elevations.
To find the difference between the elevation at Zabriskie Point and Furnace Creek in Death Valley National Park, follow these steps:
Use the formula for subtracting negative numbers:
Difference = Elevation at Zabriskie Point - (Elevation at Furnace Creek)
Given elevations:
Elevation at Zabriskie Point = 648 feet
Elevation at Furnace Creek = -178 feet
Substitute these values into the formula:
Difference = 648 - (-178) feet
Remember that subtracting a negative is the same as adding the positive:
Difference = 648 + 178 feet
Perform the addition:
Difference = 826 feet
Therefore, the difference between the elevation at Zabriskie Point and Furnace Creek is 826 feet.
