Answer:

$2

Step-by-step explanation:

Step-by-step explanation:

Given, John had $30

after riding 5 rides, He had $20

( Let's subtract the balance and the balance he had after ride )

$(30 - 20)

$10

Therefore, Each ride costs = $10 ÷ 5

(dividing 10 and 5, we get 2)= $2

Hence, It took $2 for a ride.

Brand B of shoes is most likely to have defects in their shoes.

A relative value indicating hundredth parts of any quantity.

Brand A was found to have 5 out of 600 pairs of shoes with a defect.

Brand B was found to have 5 out of 250 pairs of shoes with a defect.

As per the data the brand B shoes get more often defected.

For every 250, 5 are defected,

The percent probability for brand A is

= 5/250*100

= 2%.

while Brand B

65.22 % of teachers ordered the salad bar

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

According to the question

A school cafeteria offers three lunch options on Mondays:

Spaghetti, sub sandwiches, or salad bar.

Percentage of teachers ordered the salad bar

Total number of teachers = 23

Total number of teachers ordered the salad bar = 15

= [tex]\frac{15}{23}[/tex]

= 0.6522

= 65.22%

Thus, 65.22 % of teachers ordered the salad bar

Solution

x=10

Equation

x+3= -7

Solution

x= -10

Equation

5x= -2

Solution

x= -0.4

Equation

0.5x = 5

Solution

x= 10

All the solutions of the expressions are,

1) x = 10

2) x = -10

3) x = -0.4

4) x = 10

We have to given that,

All expressions are,

1) x - 6 = 4

2) x + 3 = - 7

3) 5x = - 2

4) 0.5x = 5

Now, We can simplify the expression as,

x - 6 = 4

x = 4 + 6

x = 10

x + 3 = - 7

x = - 7 - 3

x = - 10

5x = - 2

Answer:

C. The radii of both bases are the same.

Step-by-step explanation:

Answer: 3.90125×10⁻³

Step-by-step explanation:

The scientific notation consists of two parts

So the final version should be: a×10ˣ

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

STEP ONE. Number based

We are given 3,901.25

In order to make it within the range of a, we should move the decimal to the left three places, or divide the number by 10³, which is times 10⁻³

We get 3.90125

STEP TWO: Exponent based

Since we changed the number by 10⁻³,  this will be our exponent-based.

Therefore, it is 3.90125×10⁻³

Answer:

30

Step-by-step explanation:

Ah okay, so this is a simple proportion.

If 1 rose = 6 tulips, then you just multiply however many roses you have by 6. So in your case, 5 x 6 = 30. So in short, for every 5 roses Genny uses, she will use 30 tulips.

Answer:

30 tulips

Step-by-step explanation:

This question gives us the amount of tulips for one rose.

Let us make 1 rose as r and a tulip is t. Now write an equation for the tulips.

Tulip = 6r

If we have 5r:

5r = 6t x 5

Solve!

5r = 30t

5 roses = 30 tulips

Answer:

The side lengths of the larger polygon are;

15 cm

20.625 cm

16.875 cm

9.375 cm

13.125 cm

Step-by-step explanation:

Firstly, we need to calculate the perimeter of the first polygon

Mathematically, we can get this by adding the side lengths together

We have this as;

5 + 7 + 8 + 11 + 9

= 40 cm

so we have the ratio of the lengths of both as;

75 cm/40 cm = 1.875

Now, we simply will multiply the lengths of the smaller polygon by 1.875

So we have the side lengths of the bigger polygon as;

1.875 * 5 = 9.375 cm

1.875 * 7 = 13.125 cm

1.875 * 8 = 15 cm

1.875 * 9 = 16.875 cm

1.875 * 11 = 20.625 cm

Answer:

113.04 cm³

Step-by-step explanation:

diameter = 6cm

so radius = 3cm

Volume of sphere = [tex]\frac{4}3}[/tex][tex]\pi r^3[/tex]

= 4 * 3.14 * 3 * 3 *3 / 3

Answer:

Step-by-step explanation:

6³ is not equal to 18, that is 6x3

6³= 6x6x6=216

so the correct volume is V= 904.7 cm³

Answer:

ur steps would be 9*1*9  = 9^3

Step-by-step explanation:

Any number in the power of 0 = 1

Answer:

9^4

Step-by-step explanation:

Let's review the equation:

9 · 9^0 · 9^3

Anything to the power of 0 is equal to one, so 9^0 is one

That leaves us with 9 · 1 · 9^3

9 · 1 = 9

9^1 · 9^3 = 9^4

so..

9 · 9^3

[tex] \boxed{(6, -3)} [/tex]

Step-by-step explanation:

Given the ratio 5:3

and Points A and B where A is located at (-6, 3), and B is located at (26, -13).

Let point A be [tex] (x_{1}, y_{1}) [/tex], and let point B be [tex] (x_{2}, y_{2}) [/tex].

(-6, 3) → [tex] (x_{1}, y_{1}) [/tex].

(26, -13) → [tex] (x_{2}, y_{2}) [/tex].

Let 5 be n, and 3 be m.

5:3 → n:m

[tex] (\frac{nx_{1} + mx_{2}}{n+m}, \frac{ny_{1} + my_{2}}{n + m}) [/tex].

To solve, just substitute these variables into the expressions of these coordinates to get the answer.

[tex] (\frac{nx_{1} + mx_{2}}{n+m}, \frac{ny_{1} + my_{2}}{n + m}) [/tex] →

[tex] (\frac{(5)x_{1} + (3)x_{2}}{(5)+(3)}, \frac{(5)y_{1} + (3)y_{2}}{(5) + (3)}) [/tex] →

[tex] (\frac{(5)(-6)+ (3)(26)}{(5)+(3)}, \frac{(5)(3)+ (3)(-13)}{(5) + (3)}) [/tex] →

[tex] (\frac{-30 + 78}{8}, \frac{15+ -39}{8}) [/tex] →

[tex] (\frac{78 – 30}{8}, \frac{15 – 39}{8}) [/tex] →

[tex] (\frac{48}{8}, \frac{-24}{8}) [/tex]

→

[tex] (\frac{6}{1}, \frac{-3}{1}) [/tex]

→

[tex] (6, -3) [/tex].

Thus the coordinates of B are:

[tex] \boxed{(6, -3)} [/tex]

Answer:

Step-by-step explanation:

AB:BC::5:3

let the coordinates be (x,y)

[tex]x=\frac{nx1+mx2}{m+n} \\=\frac{3(-6)+5(26)}{5+3} \\=\frac{-18+130}{8} \\=\frac{112}{8} \\=14\\y=\frac{ny1+my2}{m+n} \\=\frac{3(3)+5(3)}{5+3} \\=\frac{9+15}{8} \\=\frac{24}{8} \\=3\\[/tex]
