Answer: The answer is C) y= 2/3x-3

Step-by-step explanation:

i figure it out

Answer:

C

Step-by-step explanation:

so obviously your slop is 2/3. so it starts with y=2/3. so B is out of the question. since the slope is x in the equation, you still have to add the x in the equation; y=2/3x

Answer:

a) 26.3% b) 58.5%

Step-by-step explanation:

(72/123) * 100 = 58.5

Vineisha earned 110 percent on the science quiz which was about the phases of the moon.

Vineisha earned 22 out of 20 points on her science quiz over the phases of the moon

The percent earned can be calculated by dividing 20 by 22 and then multiplying the result by 100

22/20 × 100

= 1.1 × 100= 110

Hence the percent she earned on the quiz is 110%

Answer:

The length of the shorter part of the wire is 24 centimeters.

Step-by-step explanation:

Let [tex]L[/tex] the total length of the piece of wire, where [tex]L-x[/tex] and [tex]x[/tex] are the perimeters of the greater and lesser squares. All lengths are measured in centimeters. Since squares have four sides of equal length, the side lengths for the greater and lesser squares are [tex]\frac{L-x}{4}[/tex] and [tex]\frac{x}{4}[/tex]. From statement we find that the sum of the areas of the two squares ([tex]A[/tex]), measured in square centimeters, is represented by the following expression:

[tex]A = \left(\frac{L-x}{4} \right)^{2}+\left(\frac{x}{4} \right)^{2}[/tex] (1)

And we expand this polynomial below:

[tex]A = \frac{L^{2}-2\cdot L\cdot x +x^{2}}{16} + \frac{x^{2}}{16}[/tex]

[tex]A = \frac{L^{2}-2\cdot L\cdot x +2\cdot x^{2}}{16}[/tex]

[tex]2\cdot x^{2}-2\cdot L\cdot x +L^{2}-16\cdot A = 0[/tex] (2)

If we know that [tex]L = 76\,cm[/tex] and [tex]A = 205\,cm^{2 }[/tex], then the length of the shorter part of the wire is:

[tex]2\cdot x^{2}-152\cdot x +2496 = 0[/tex]

By the Quadratic Formula, we determine the roots associated with the polynomial:

[tex]x_{1} = 52\,cm[/tex], [tex]x_{2} = 24\,cm[/tex]

The length of the shorter part of the wire corresponds to the second root. Hence, the length of the shorter part of the wire is 24 centimeters.

The area of the circle is around 908 square centimeters, so the correct option is A.

The area of a circle of radius R is given by:

A = pi*R²

Where pi is an irrational number, and we can write it as pi = 3.14

Here we can see that the radius of the circle is 17cm, then we can replace that in the area formula to get:

A = 3.14*(17cm)² = 908 cm²

Then the corret option is A.

The answer i got is -1.55, im not sure though

The value of the given algebric expression is x - y when x=−5 1/4 and y=−6.8 will be 2.05.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

An expression is a mathematical proof of the equality of two mathematical expressions.

As per the given expression, x - y

x = - 5 1/4 = (-5 x 4 + 1)/4 = -19/4 = -4.75

y = -6.8

Substitute x and y into the above expression,

-4.75 - (-6.8) = 2.05

Hence "The value of the given algebric expression is x - y when x=−5 1/4 and y=−6.8 will be 2.05".

Answer:

Ounces of green paint needed = 13.8

Step-by-step explanation:

Blue paint : green paint = 25 : 115

how many ounces of green paint should she mix with 3 ounces of blue paint?

Let

Ounces of green paint needed = x

Blue paint : green paint = 3 : x

Equate both ratios

25 : 115 = 3 : x

25/115 = 3/x

25 * x = 115 * 3

25x = 345

x = 345/25

x = 13.8 ounces

Ounces of green paint needed = 13.8

The number of cheery pieces in the box are [tex]18[/tex].

Step-by-step explanation:

Let the number of orange pieces in the box be [tex]x[/tex].

The box contains three times as many cherry pieces as orange pieces.

So, the number of cherry pieces in the box be [tex]3x[/tex].

It has four more grape pieces than cherry pieces.

So, the number of grape pieces in the box be [tex]3x+4[/tex].

There are [tex]46[/tex] total pieces in the box.

So, [tex]x+3x+3x+4=46[/tex]

[tex]\Rightarrow 7x+4=46[/tex]

[tex]\Rightarrow 7x=46-4[/tex]

[tex]\Rightarrow 7x=42[/tex]

[tex]\Rightarrow x=\frac{42}{7}[/tex]

[tex]\Rightarrow x=6[/tex]

So, the number of cherry pieces [tex]=3x=3\times 6=18[/tex].

Hence, the number of cheery pieces in the box are [tex]18[/tex].
