A student has a 90, 84, and an 86 on their first 3 tests. What possible scores would the student need
Ugo [173]
The student would have to score 100% on their next test to brung their average up to 90. Here is why;
90+84+86=260
(260+?)/4=90
(260+100)/4=90
360/4=90
This is done to get the mean (or average) of a group of numbers by adding all the numbers and dividing by the amount of numbers you added together. Here it is divided by 4 because of the three tests he has taken and the test he will take.

What is the direct linear variation equation for the relationship?
defon
\bf \begin{array}{cccccclllll}
\textit{something}&&\textit{varies directly to}&&\textit{something else}\\ \quad \\
\textit{something}&=&{{ \textit{some value}}}&\cdot &\textit{something else}\\ \quad \\
y&=&{{ K}}&\cdot&x
\\ \\
&&  y={{ K }}x
\end{array}
\\ \quad \\

\begin{cases}
y=4\\
x=12
\end{cases}\implies y=Kx\implies 4=K\cdot 12

solve for "K", to see what "K" is, or the "constant of variation",
once you found K, plug it back in y=Kx, and that's the equation

4 Celeste uses 24 inches of ribbon from a spool that holds 36 inches of ribbon. Which shows equivalent representations for the p
kaheart [24]

We are given that 24 out of 36 inches of ribbon is used. The percentage that is used is equivalent to:

\frac{24}{36}=\frac{2}{3}

Therefore, the percentage is:

\frac{2}{3}\times100=0.66\times100=66\text{ percent}

The gradient of A(6,2) B(3,-3)
Anestetic [448]

Answer:

\sf  gradient: \dfrac{5}{3}

Explanation:

\sf slope/gradient: \dfrac{y_2 - y_1}{x_2- x_1} \ \  where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points

Given points: A(6,2), B(3,-3)

\rightarrow \sf  slope: \dfrac{-3-2}{3-6}

\rightarrow \sf  slope: \dfrac{-5}{-3}

\rightarrow \sf  slope: \dfrac{5}{3}

Carmen can buy bottles of paint for $2.00 each and boxes of colored pencils for $3.50 each. She can spend no more than $42 on ar
Lemur [1.5K]

Answer:

Step-by-step explanation:

Let x = the number of bottles of paint that Carmen can buy

Let y = the number of boxes of colored pencils that Carmen can buy

A bottle of paint costs $2

A box of colored pencils costs $3.50

She can spend no more than $42 on art supplies. This means

She can buy bottles of paint worth 2×x = $2x

She can buy boxes of colored pencils

worth 3.5 × y = $3.5y

Since the total amount she can spend cannot exceed $42, the equation becomes

2x + 3.5y lesser than or equal to 42

This is shown in the attached photo

b) three different solutions to the inequality would be three different possible values that x and y can take. These are

x = 7 while y = 8

x = 10 while y = 6

x = 14 and y = 4
