Answer:
20 %
Step-by-step explanation:
four blue shirts, two green shirts, two gray shirts, one white shirt and one red shirt = 10 shirts
P(red) = number of red shirts / total
= 2/10
= 1/5
=20 %
Answer:
10%
Step-by-step explanation:
4 blue
2 green
2 gray
1 white
1 red
4 + 2 + 2 + 1 + 1 = 10
each t-shirt = 10 percent
so 1 red t-shirt = 10%

the triple of the area of a square is 1587 m2 What is the side of the square?
Answer:
23 m
Step-by-step explanation:
Given that triple the area = 1587 m² , then
area = 1587 ÷ 3 = 529 m²
The area of a square = s² ( s is the measure of the side ), thus
s² = 529 ( take the square root of both sides )
s = [tex]\sqrt{529}[/tex] = 23 m

Determine if the sequence -184, -207, -230, -253,... is arithmetic or geometric. Then identify the next term in
the sequence.
a arithmetic; -23
b. arithmetic; -276
c. geometric; -23
d. geometric; -276
Answer:
a arithmetic; -23
Step-by-step explanation:
this is not geometric sequence as we don't see multiplication effect in the terms
let's see what is the difference in terms
-207- (-184)= -23
-230- (-207)= -23
-253- (-230)= -23
we can state it is an AP with common difference of -23

g(0) =3
Then put this into f(x)
f(g(0) ) = f(3) = 5*3 = 15
A ship is sailing due west …
Plz answer !!
Answer:
8.75° south of west
26.3 mph
Step-by-step explanation:
Let's say that east is +x and north is +y.
The sailor's horizontal velocity is -26 mph. The vertical velocity is -4 mph. So the velocity vector is in the 3rd quadrant. The direction is:
θ = tan⁻¹(-4 / -26)
θ = 188.75°, or 8.75° south of west.
The magnitude of the speed is:
v = √((-4)² + (-26)²)
v = 26.3 mph
Choose the equation of the horizontal line that passes through the point (2, 4). (5 points) y = 2 x = 2 y = 4 x = 4

The diagram shows a cuboid.
6 cm
The height of the cuboid is 6 cm.
The volume of the cuboid is 90 cm.
What is the area of the shaded face?
Answer:
length x width x 6 = 90
area of shaded face = 15
The area of the shaded region is 15 square cm.
What is area?
The space occupied by a flat shape or the surface of an object is called area.
Formula for the area of rectangle[tex]Area = lb[/tex]
Where,
l is the length of the rectangle.
b is the breadth of the rectangle.
What is volume?A volume is simply defined as the amount of space occupied by any three-dimensional solid.
Formula for volume of cuboidvolume = length × breadth × height
According to the given question.
We have,
Height of the cuboid = 6cm
Volume of the cuboid = 90 cubic cm.
⇒ length × breadth × height = 90
⇒ length × breadth × 6 = 90
⇒ length × breadth = [tex]\frac{90cm^{2} }{6cm}[/tex]
⇒ length × breadth = 15 square cm....(i)
Since, the area of shaded region = length × breadth
From (i)
Length × breadth = 15 square cm .
Hence, the area of the shaded region is 15 square cm.

The math team wraps gifts as a way to raise money for traveling to competitions. They offer two choices: a plain wrapping or a decorative wrapping with bows. The table represents the money raised over a busy shopping weekend. A 3-column table titled Gift-Wrapping Fundraiser has 3 rows. The first column is labeled Plain Gifts Wrapped with entries 10, 25, 16. The second column is labeled Decorative Gifts Wrapped with entries 9, 12, 12. The third column is labeled Total Raised in dollars with entries 47, 86, 68. Which statement describes the amounts the team charged for wrapping gifts? The team charged $1 to wrap a gift with no bow and $2 to wrap a gift with a bow. The team charged $2 to wrap a gift with no bow and $3 to wrap a gift with a bow. The team charged $3 to wrap a gift with no bow and $4 to wrap a gift with a bow. The team charged $4 to wrap a gift with no bow and $5 to wrap a gift with a bow.
Answer:
The team charged $2 to wrap a gift with no bow and $3 to wrap a gift with a bow.
Step-by-step explanation:
Gift-Wrapping Fundraiser
Plain Gifts Wrapped Decorative Gifts Wrapped Total Raised in dollars
10 9 47
25 12 86
16 12 68
Let's define:
x: $ charged per gift for Plain Gifts Wrapped
y: $ charged per gift for Decorative Gifts Wrapped
From 2nd 3rd row:
25x + 12y = 86
16x + 12y = 68
Subtracting them:
25x + 12y - (16x + 12y) = 86 - 68
9x = 18
x = 18/9 = 2
Replacing x = 2 into the first equation:
25(2) + 12y = 86
12y = 86 - 50
12y = 36
y = 36/12 = 3
Answer:
The team charged $2 to wrap a gift with no bow and $3 to wrap a gift with a bow.

PO=100cm
P=23 degrees
Answer:
40 cm
Step-by-step explanation:
In the right triangle PNO:
∠N = 90°PO = 100cm (the hypotenuse of the triangle)∠P = 23°∠O = 90° - 23° = 67°side NO is adjacent to ∠OBy definition:
cos(β) = adjacent/hypotenuse
Replacing with data and solving for NO:
cos(∠O) = NO/PO
2/5 = NO/100
NO = (2/5)*100
NO = 40

The function ƒ(x) = 4x + 1 is transformed to g(x) = 2x + 1. What type of transformation has occurred? A) Reflection and Vertical Translation B) Rotation C) Reflection D) Rotation and Vertical Translation
Answer:
B) Rotation
Step-by-step explanation:
The only difference between functions f(x) and g(x) is the slope. To get from f(x)=4x+1 to g(x)=2x+1, you would need to rotate slightly clockwise about point (0,1) - the y-intercept. This would make the graph less steep (2x is less steep than 4x) while still retaining the (0,1) y intercept.

Which statement describes how to determine if a relation given in a table is a function?
A. If none of the output values are repeated, the relation is a function.
B. If none of the input values are repeated, the relation is a function.
C. If any of the input values are equal to the output values, the relation is a function.
D. If all the output values are paired with the same input value, the relation is a function.
Answer: B
Step-by-step explanation: A function is a relation in which each input value is paired to exactly one output value.
Technically, if you had the same input value twice and the same output value corresponded to each of those, it would still be a function because you are just repeating what you have twice.
However, most teachers want to think of it as each input value must have exactly one corresponding value to be a function.
Answer:
B. If none of the input values are repeated, the relation is a function.

What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Let the numbers be x, y, and z.
The sum of three numbers is 10.
x + y + z = 10 …1
The first number minus the second plus the third is 6.
x – y + z = 6 …2
The first minus the third is 2 more than the second.
x – y = z + 2 …3
Add equation 1 and 3, we have
x + x + z = 10 + z + 2
2x = 12
x = 6
Subtract equation 2 from 1, we have
2y = 4
y = 2
Then the value of z will be
6 + 2 + z = 10
z = 2
