Answer:

$12.80 per pound

Step-by-step explanation:

Since there are 16 ounces in 1 pound, we multiply $0.80 by 16 ounces to find how much cinnamon costs per pound. The answer is $12.80.

Hope this helped, Have a Wonderful Day!!

Answer:

$9.60 per pound

Step-by-step explanation:

- 4 ounces = 2.40 each

- 2.40 x 4 (4 because 4x4 is 16 and there are 16 ounces in a pound)

= $9.60

Answer:

13 hours 55 minutes

Step-by-step explanation:

A train leaves at 5:35

The train arrives at its destination at 18:20

Therefore the time interval between 5:35 and 18:20 is

13 hours 55 minutes

Hence the journey is 13 hours 55 minutes long

Answer:

477.47 revolutions

Step-by-step explanation:

From the information given:

The formula for calculating the circumference = 2π r

Given that the radius of each wheel = 25 centimeter

Then, the circumference = 2 π (25)

= 50π cm

The distance traveled in 5 minutes is as follows:

Given that:

The speed = 45 km/ hour

i.e.

1 hour = 45 km

In an hour, we have 60 minutes

So, 60 minutes = 45 km

1 minute = 45/60 = 0.75 km

To cm;

0.75 km = (0.75 × 1000) m = 750 m

750 m = 750 × 100 = 75,000 cm

∴

The number of revolution in 5 minutes sInce 1 revolution =  50π cm is:

=  75,000 cm/ 50π cm

= 477.47 revolutions in 5 minutes

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: is that the question??

Step-by-step explanation:

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]

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:

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.

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Here, we want to compare the graph of g(x) and f(x)

Looking at the given equations, the difference between the two is that we have 5 subtracted from one of the equations

What this means is that we are moving down 5 units away from the graph of f(x) to get the graph of g(x)

Thus, option D is the correct answer

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

Step-by-step explanation:

Step 1: Define

A = 50°

B = 62°

a = 4

Step 2: Solve for b

Answer:

Below.

Step-by-step explanation:

a.    Φ^2 − Φ − 1 = 0

Φ2 − Φ = 1

(Φ - 0.5)^2 - 0.25 = 1

(Φ - 0.5)^2 = 1.25

Φ - 0.5 = √(1.25)      (We only take the positive root).

Φ  = 0.5 + √(1.25)

b. I used Completing the square.

c.  Φ is irrational That is it cannot be represented as a fraction a/b and because of this it can only be approximated by a decimal.

Answer:

A has 3 factors: 31 x 37 x 37

Step-by-step explanation:

31 and 37 are prime numbers so there are no other factors. due to the square the factor 37 shows up twice.

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]
