Answer:

38/7

Step-by-step explanation:

question: 5*3/7

      we should first cross multiply 5 with 7 and add the 3 to the product.

      the formula for solving any question like this is :-

               ( whole no. multiplied with denominator ) + numerator

                                                 denominator

Answer:

(2,4), (6,4), (2,-2), (6,-2)

Step-by-step explanation:

To dilate a figure multiply 2(x,y)

2(1,2)  = (2,4)

2(3,2) = (6,4)

2(1,-1) = (2,-2)

2(3,-1) = (6,-2)

Answer:

4:1 & 8:2

Step-by-step explanation:

The ratio is 32/8

When simplified it will be 4/1

Since the next ratio is 8/x, make the equation 4x = 8

Because x = 2 the ratio will be 8/2

C. 172.5 ft²

Step-by-step explanation:

area of triangular roof piece is 1/2(10)(6.9) = 34.5

there are 5 of them so 34.5 x 5 = 172.5 ft²

===========================================

Work Shown:

40 coins total

16 are dimes

40-16 = 24 coins are not dimes

Half of this is 24*(1/2) = 12 which are quarters. The other half (12) are pennies and nickels

n = number of nickels

p = number of pennies

This means n+p = 12 so that we have 12 pennies and nickels combined.

"There are 2 nickels for every penny", so we can write n = 2p. If p = 1, then n = 2. If p = 2, then n = 4, etc. Whatever p is, we double it to get n.

So,

n+p = 12

2p+p = 12

3p = 12

p = 12/3

p = 4, we have 4 pennies

n = 2p

n = 2*4

n = 8 and 8 nickels

-----------------------------------------

Here are all the coin counts

16+12+8+4 = 40 coins total

Answer:

Option (B) is correct, 4 pennies.

I would try 10 again but this time put the degree sign in. Sometimes the computer registers in incorrect if it doesn't have a degree sign

Step-by-step explanation:

Also, this is a random note but in geometry, minutes and seconds are classified as smaller units in angles than degrees. 60 minutes is a degree and 60 seconds is a minute so that means 3600 seconds is a degree.

Answer:

Option a) $ 82,531.59

Step-by-step explanation:

The Formula for Future value =

Present value (1 + r/n)^nt

From the question

Present value = $51,123.21

Interest rate (r) = 2 3/8 % = 2.375% = 0.02375

n = compounding frequency = compounded daily = using the traditional bankers rule of 30 days = 30 × 12 months = 360

T = Time duration in years = 20 years and 2 months = 20.1667

Future value = $ 51,123.21(1 + 0.02375/260)^20.1667 × 360

Future value = $ 82,531.59

Step-by-step explanation:

Answer:

Assume that 1900km^2 is 1900.

If that happens, The equation of that will look like...

1900 - (1900 x 7.75% x 14)%.

1900 x 7.75% are 147.25.

and 147.25 x 14 are 2061.5.

so... there will be no forest after 14 years.(harsh)

Hope it helps!

The area of the forest after 14 years would be 614.1617 km².

We have,

Let's denote the initial area of the forest as A₀ = 1900 km².

The decrease in the area each year is 7.75%, which means that the remaining area after each year is 92.25% of the previous year's area.

i.e

[tex]A_i= A_0[/tex] (1 - 0.0775)

where Aᵢ is the area after i years.

To find the area after 14 years.

A₁₄ = 1900 x [tex](1 - 0.0775)^{14}[/tex]

      = 1900 x 0.3232430884671

      = 614.1617 km²

Therefore,

The area of the forest after 14 years would be 614.1617 km².

Answer:

He wrote the rate incorrectly

Step-by-step explanation:

Camille's calculation

(48/$3.84)(?/s1)

48x/3.84

=$13.79

The correct calculation

(48/$3.84)(?/s1)

48x/3.84

=$12.50

To find the error in Camille's calculation

(48/$3.84)(?/s1)

48x/3.84

=$13.79

We will divide 48 ounces of jelly by $13.79 to get the rate

48/13.79

=$3.48

Therefore, Camille wrote the rate incorrectly by interchanging .84 after the decimal for .48

Answer:

D

Step-by-step explanation:

The required measure of XZ (the minor arc) is 116. Option A is correct.

In the figure, a circle gave with 3 arc divisions XY, YZ, and XZ. And angle 58 at point y.

The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by. (x-h)²+(y-k)²=2 where h, k is the coordinate of the circle's center on the coordinate plane and r is the circle's radius.

Since by the property of the circle the angle subtended by arc to the vertex corresponding to the center is half the measure of the angle subtended by the arc to the center.
so, let the center of the circle is o.
Now,
measure of XZ = 2 * 58
                         =  116

Thus, the required measure of XZ (the minor arc) is 116.

Answer:

  y = 4

Step-by-step explanation:

The line x=8 is a vertical line. The perpendicular line will be horizontal, with a slope of 0. In order for it to go through the given point, the y-intercept must match the y-value of the point. The equation is ...

  y = 0x +4 . . . . . slope-intercept form with slope explicitly shown as 0

Answer:

a) Number of hours it takes 1 centimetre of snow to form in Harper's yard = (1/5) hour = 0.20 hour

b) Centimetres of snow that accumulate per hour = 5 cm

Step-by-step explanation:

Complete Question

We can calculate the depth d of snow, in centimeters, that accumulates in Harper's yard during the first h hours of a snowstorm using the equation d=5h.

a) How many hours does it take for 1 centimeter of snow to accumulate in Harper's yard? hours

b) How many centimeters of snow accumulate per hour? centimeters

Solution

The depth of snow, d, in centimetres that accumulates in Harper's yard in h hours is given d = 5h

a) Number of hours it takes 1 centimetre of snow to form in Harper's yard.

d = 5h

d = 1 cm

h = ?

1 = 5h

h = (1/5) = 0.20 hour

b) Centimetres of snow that accumulate per hour.

d = 5h

In 1 hour, h = 1 hour

d = ?

d = 5 × 1 = 5 cm

Answer: The polynomial has 3 terms and a degree of 10.

Step-by-step explanation:

The given polynomial: [tex]5s^6t^2 + 6st^9 - 8s^6t^2 - 6t^7[/tex]

Here, two terms [tex]5s^6t^2[/tex] and [tex]8s^6t^2[/tex] have same power for s and t i.e. they are like terms.

Combine like terms , we get

[tex]6st^9 - 3s^6t^2 - 6t^7.[/tex] i.e. there are 3 terms.

Degree of [tex]6st^9[/tex]  is 1+9=10;

Degree of [tex]- 3s^6t^2[/tex] is 6+2=8;

Degree of  [tex]- 6t^7[/tex]  is 7.

Since degree of the polynomial = highest degree i.e. 10

Hence, the polynomial has 3 terms and a degree of 10.

The statement which is true about the polynomial 5s⁶t² + 6st⁹ – 8s⁶t² – 6t⁷ is; It has 4 terms and a degree of 10.

Discussion:

By counting the number of terms in the polynomial;

Additionally, the degree of the polynomial is 10.

This is from the term with the highest degree which is; 6st⁹; where s has degree 1 and t has degree 9; total of which is; 10.

Step-by-step explanation:

For the 1st it is 25,000 because that is what he starts off with and there is an x behind 1000 because it depends on how many years he receives the bonus. For example, if he was there for 3 years the equation would look like 25000+1000(3).

Statement #1:

Since there are 30 total pizzas then the amount of pizzas with 12 slices is 60% of 30 which is 18. Then you can multiply 18 by 12 to get the amount of slices in the large pizzas with 12 slices:

18 × 12 = 216

-----------------------------------------------------------------------------------------------------------------

60% of the pizzas have 12 slices each. In total, there are 216 slices in these pizzas.

Statement #2

There are 12 remaining pizzas which means that 12 × 10 = 120 is the amount of slices in total of the smaller pizzas.

-----------------------------------------------------------------------------------------------------------------

40% of the pizzas have 10 slices each. In total, there are 120 slices in these pizzas.

Statement #3

To get the total amount of pizzas you simply add both of the previous solutions:

216 + 120 = 336

-----------------------------------------------------------------------------------------------

Altogether, there is a total of 336 slices of pizza.

Answer:

Coordinate d

Step-by-step explanation:

Answer: d is larger

c = -2 and d = -1

====================================================

Explanation:

We have c = -2 as this is the same as the x coordinate of (-2,-1), which is the point directly below (c,5).

The point (3,d) is on the same horizontal level as (-2,-1), so the y coordinates must match up. We therefore have d = -1.

Comparing c = -2 and d = -1, we see that d = -1 is larger as it is to the right of -2.
