April wants to paint three walls of her bedroom. The walls are each 90 square feet. Paint is only sold in whole quarts, and each quart of paint will cover 100 square feet. How many quarts of paint must she purchase to have sufficient paint for this job?

I think there is a little error in your question. I guess You mean 60 vaccinations instead of 606060. I solved using 60 vaccinations.

Answer:Dr. Potter gave 32 polio vaccines and 28 measles vaccinations that year.

Step-by-step explanation:

STEP 1

Let number of polio vaccines be x

and number of measles vaccine be y

such that

total does of 60 vaccinations be expressed as

x+y = 60---- equation 1

And number of doses for both  vaccine to total 184 doses taken be expressed as

4x + 2y= 184 ---- equation 2

Step 2--- solving

x+y = 60---- equation 1

4x + 2y= 184 ---- equation 2

Making x the subject of formula in equation 1 and substituting it in equation 2

x= 60-y

4(60-y) +2y- 184

240-4y+2y=184

240-184= 4y-3y

56= 2y

y= 58/2 = 28

To get x , put the value of y=28 in equation 1 and solve

x+y=60

x=60-28

x=32

Therefore Dr. Potter gave 32 polio vaccines and 28 measles vaccinations that year.

Answer: -3

Answer:

B. -13w - 7

Step-by-step explanation:

Combine -6w and -7w together to get -13w as the first part of your answer since you are subtracting from a negative to get a negative answer and combine -8 and 1 together to get -7 since you are adding 1 from -8 to go up.

Answer:

Mario brought 5 magazines

Step-by-step explanation:

If you just add $12.60 and $2.25 together then keep adding $2.25 until you get to $23.85, you'll get your answer.

So like,  

(1) 12.60 + 2.25 = 14.85

(2) 14.85 + 2.25 = 17.1

(3) 17.1 + 2.25 = 19.35

(4) 19.35 + 2.25 = 21.6

(5) 21.6 + 2.25 = 23.85  

So the total would be 5. Mario bought 5 magazines.

Answer: is that the question??

Step-by-step explanation:

Answer:

The coordinates of B' and C' are [tex]B'(x,y) = (4, -7)[/tex] and [tex]C'(x,y) = (-1, -8)[/tex], respectively.

Step-by-step explanation:

From the Linear Algebra, we define the translation of a given point as:

[tex]O'(x,y) = O(x,y) + T(x,y)[/tex] (1)

Where:

[tex]O(x,y)[/tex] - Original point, dimensionless.

[tex]T(x,y)[/tex] - Translation vector, dimensionless.

[tex]O'(x,y)[/tex] - Translated point, dimensionless.

If we know that [tex]A'(x,y) = (1, -5)[/tex] and [tex]A(x,y) = (4,-2)[/tex], then the translation vector is:

[tex]T(x,y) = A'(x,y)-A(x,y)[/tex] (2)

[tex]T(x,y) = (1,-5)-(4,-2)[/tex]

[tex]T(x,y) = (-3,-3)[/tex]

If we know that [tex]B(x,y) = (7,-4)[/tex], [tex]C(x,y) = (2,-5)[/tex] and [tex]T(x,y) = (-3,-3)[/tex], then the translated points are, respectively:

[tex]B'(x,y) = B(x,y)+T(x,y)[/tex] (3)

[tex]B'(x,y) = (7,-4) +(-3,-3)[/tex]

[tex]B'(x,y) = (4, -7)[/tex]

[tex]C'(x,y) = C(x,y) +T(x,y)[/tex]

[tex]C'(x,y) = (2,-5) + (-3,-3)[/tex]

[tex]C'(x,y) = (-1, -8)[/tex]

The coordinates of B' and C' are [tex]B'(x,y) = (4, -7)[/tex] and [tex]C'(x,y) = (-1, -8)[/tex], respectively.

Complete question :

A local Charity receives 1/3 of funds raised during a craft fair and bake sale. The total amount given to the charity was $137.45. How much did the bake sale raise

Answer:

$412.35

Step-by-step explanation:

Given that:

Fraction Given to charity from bake sale = 1/3 of amount raised

Amount given to charity = $137.45

Let amount raised from bake sale = x

Hence,

1/3 of x = 137.45

x / 3 = 137.45

x = 137.45 * 3

x = $412.35

Amount raised from bake sale = $412.35

Answer:

The fraction of the beads that are red is

Step-by-step explanation:

Algebraic Expressions

A bag contains red (r), yellow (y), and blue (b) beads. We are given the following ratios:

r:y = 2:3

y:b = 5:4

We are required to find r:s, where s is the total of beads in the bag, or

s = r + y + b

Thus, we need to calculate:

[tex]\displaystyle \frac{r}{r+y+b} \qquad\qquad [1][/tex]

Knowing that:

[tex]\displaystyle \frac{r}{y}=\frac{2}{3} \qquad\qquad [2][/tex]

[tex]\displaystyle \frac{y}{b}=\frac{5}{4}[/tex]

Multiplying the equations above:

[tex]\displaystyle \frac{r}{y}\frac{y}{b}=\frac{2}{3}\frac{5}{4}[/tex]

Simplifying:

[tex]\displaystyle \frac{r}{b}=\frac{5}{6} \qquad\qquad [3][/tex]

Dividing [1] by r:

[tex]\displaystyle \frac{r}{r+y+b}=\displaystyle \frac{1}{1+y/r+b/r}[/tex]

Substituting from [2] and [3]:

[tex]\displaystyle \frac{r}{r+y+b}=\displaystyle \frac{1}{1+3/2+6/5}[/tex]

Operating:

[tex]\displaystyle \frac{r}{r+y+b}=\displaystyle \frac{1}{\frac{10+3*5+6*2}{10}}[/tex]

[tex]\displaystyle \frac{r}{r+y+b}=\displaystyle \frac{10}{10+15+12}[/tex]

[tex]\displaystyle \frac{r}{r+y+b}=\displaystyle \frac{10}{37}[/tex]

The fraction of the beads that are red is [tex]\mathbf{\frac{10}{37}}[/tex]

-2w² + -16w

Step-by-step explanation:

-2w(w+8)

Multiply each term by -2w

(-2w * w) + (-2w * 8)

-2w² + -16w

Answer:

-2[tex]w^2[/tex] - 16w

Step-by-step explanation:

multiply w and 8 by -2w.

when you multiply w by 2w, you get -2[tex]w^2[/tex] and 8 times -2w = -16w

-2[tex]w^2[/tex] - 16w

Answer:

The answer is below

Step-by-step explanation:

A polynominal function that describes an enclosure is v(x)=1500x-x2 where x is the length of the fence in feet what is the maximum area of the enclosure

Solution:

The maximum area of the enclosure is gotten when the differential with respect to x of the enclosure function is equal to zero. That is:

V'(x) = 0

V(x) = x(1500 - x) = length * breadth.

This means the enclosure has a length of x and a width of 1500 - x

Given that:

v(x)=1500x-x². Hence:

V'(x) = 1500 -2x

V'(x) = 0

1500 -2x = 0

2x = 1500

x = 1500 / 2

x = 750 feet

The maximum area = 1500(750) - 750² = 562500

The maximum area = 562500 feet²

Answer:

562500 feet²

Answer:

[tex]\angle F =\bold{88^\circ}[/tex]

Step-by-step explanation:

Given a [tex]\triangle FGH[/tex] with the following angles:

[tex]\text{m}\angle F = (6x-14)^{\circ}[/tex]

[tex]\text{m}\angle G = (4x-8)^{\circ}[/tex]

[tex]\text{m}\angle H = (x+15)^{\circ}[/tex]

To find:

[tex]\text{m}\angle F[/tex] = ?

Solution:

Here, we can simply use the angle sum property of a triangle to find the value of [tex]\text{m}\angle F[/tex].

As per the angle sum property of a triangle, the sum of all the interior angles a triangle is equal to [tex]180^\circ[/tex].

[tex]\angle F + \angle G + \angle H = 180^\circ[/tex]

Putting all the given values in the above equation, we get:

[tex](6x-14)^{\circ} + (4x-8)^{\circ} + (x+15)^{\circ} = 180^\circ\\\Rightarrow 11x-7=180^\circ\\\Rightarrow 11x=180+7\\\Rightarrow 11x=187\\\Rightarrow x = \bold{17}[/tex]

Putting the value of [tex]x[/tex] in [tex]\angle F[/tex]

[tex]\text{m}\angle F = (6x-14)^\circ\\\Rightarrow \text{m}\angle F = (6\times 17-14)^\circ\\\Rightarrow \text{m}\angle F = \bold{88^\circ}[/tex]
