Step-by-step explanation:
Alfredo is buying a watch for $200. He will make an initial payment of $50 and
then pay the remaining balance in payments of $15 per week.
Which function can be used to find a, the amount he will still need to pay at the
end of n weeks?
Answer:
Step-by-step explanation:
There is nothing to choose from.
However, 200-50 down payment will leave 150 left on the watch. 150 divided 15 a month is 10 months.
200=50+15(n)
200=50+15(10)
Sheila is making accessories for the soccer team. She uses 776.32 inches of fabric on headbands for 29 players and 3 coaches. She also uses 247.66 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer:
[tex]32.8\ \text{inches}[/tex]
Step-by-step explanation:
Fabric used for players and coaches is 776.32 inches.
Number of players is 29 and coaches is 3
So fabric used for each player and coach for the headbands is
[tex]\dfrac{776.32}{29+3}=24.26\ \text{inches}[/tex]
So, for the players [tex]24.26\ \text{inches}[/tex] of fabric will be used for the headbands.
Total fabric used for the wristbands is 247.66 inches
Fabric used for the wristband is
[tex]\dfrac{247.66}{29}=8.54\ \text{inches}[/tex]
So, total amount of fabric used by Shelia for the wristband and headband is [tex]24.26+8.54=32.8\ \text{inches}[/tex].

A company makes steel rods shaped like cylinders. Each rod has a radius of 2 centimeters and height of 70 centimeters. How much steel will the company need to make 243 rods? Use 3.14 for pie, and round your answer to one decimal
Answer:
213,645.6cm³
Step-by-step explanation:
Area of a cylinder is expressed as;
V = πr²h
r is the radius = 2cm
h is the height = 70cm
Get the volume of one rod;
V = πr²h
V = (3.14)(2)²(70)
V = (3.14)(4)(70)
V = 879.2cm³
one steel = 879.2cm³
243 rods = x
Cross multiply;
x = 879.2 * 243
x = 213,645.6
The company will need 213,645.6cm³ volume of steel to make 243 rods

5/3y=-(x-5) in slope intercept form
Required slope intercept form is [tex]y = - \frac{3}{5} x + 3[/tex]
What is slope ?
The slope of a line is a measure of the steepness and direction of the line. Finding the slope of lines in a coordinate plane can help predict whether the lines are parallel, perpendicular, or missing without using a compass.
The slope of any straight line can be calculated using two points on the line. The slope of the line formula calculates the ratio of "vertical change" to "horizontal change" between two different points on the line. In this article we will understand the slope finding method and its applications.
The slope of a line is defined as the change in the y-coordinate relative to the change in the x-coordinate of that line. The net change in the y-coordinate is Δy, while the net change in the x-coordinate is Δx. Thus, the change in the y-coordinate with respect to the change in the x-coordinate can be written as: m = Δy/Δx
Here given,Equation of line [tex] \frac{5}{3}y = - (x - 5)[/tex]
We want to find what is 5/3y=-(x-5) in slope intercept form ?
We want to simplify the equation.
[tex]5y = - 3(x - 5) \\ 5y = - 3x + 15 \\ y = \frac{ - 3x + 15}{5} \\ y = - \frac{3}{5} x + \frac{15}{5} \\ y = - \frac{3}{5} x + 3....(1)[/tex]
We know slope in line y = mx+c is m.
We are comparing equation (1) with y = mx + c and get [tex]m = - \frac{3}{5} [/tex]
Equation (1) is slope intercept form of 5/3y=-(x-5).
Therefore,required slope intercept form is [tex]y = - \frac{3}{5} x + 3[/tex]

y = 5.831
Reflect Here are two paint mixtures: • $$3 cups of white and $$4 cups of blue. • $$6 cups of white and $$8 cups of blue. Both mixtures make the same color because they are in equivalent ratios. Which of these mixtures is also in an equivalent ratio? $$ white $$ blue $$ white $$ blue $$ white $$ blue $$ white $$ blue
Answer:
See Explanation
Step-by-step explanation:
Given
Mixture 1:
[tex]White = 3[/tex] [tex]Blue = 4[/tex]
Mixture 2:
[tex]White = 6[/tex] [tex]Blue = 8[/tex]
Required
Determine equivalent mixtures
First, we need to calculate the unit rate of the given mixtures using:
[tex]Rate = \frac{White}{Blue}[/tex]
For mixture 1:
[tex]Rate = \frac{3}{4} = 0.75[/tex]
For mixture 2:
[tex]Rate = \frac{6}{8} = 0.75[/tex]
So, to determine which other mixture has equivalent ratio.
All you need to do is divide the number of white cups by the number of blue cups.
Since the options are not clear enough, I'll assume the following:
[tex]White = 12[/tex] [tex]Blue =16[/tex]
The rate will be:
[tex]Rate = \frac{12}{16} = 0.75[/tex]
Any rate other than 075 is not equivalent
