Answer:

2 staircases

Step-by-step explanation:

3 : 36

1 : 12

2 : 24

If katie can build three staircases to make 36 obstacles against the other player. Then 2 staircases will she need to make 24 obstacles

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

katie can build three staircases to make 36 obstacles against the other player

We need to find the number of staircases she need to make 24 obstacles.

Let us form a proportional relationship.

Consider x as the number of staircases will she need to make 24 obstacles

3/36=x/24

Apply cross multiplication

3×24=36x

72=36x

Divide both sides by 36

x=2

Hence Katie should have 2 staircases to make 24 obstacles.

Answer:

9 yards 1 foot 2 inches

Step-by-step explanation:

90inches=2.5 yards

3.5 yards

10.5 ft=3.5 feet

2.5+3.5=6 yards

6+3.5 ft=9.5 yards

9 yards  1 foot 2 inches

took me forever to write this

Answer:

342 inches, 28.5 feet, 9.5 yards.

Step-by-step explanation:

The conversion rates you need to know are as follows:

1 foot = 12 inches

1 yard = 3 feet

Because there are 3 feet in a yard, we know that there must be are 36 inches in a yard. First, we find how many inches are in 10.5 feet and 3.5 yards. This would be 10.5 * 12 resulting in 126 inches. Also, 3.5 yards as we know is 36 inches so we do 3.5 * 36 which results again in 126. Finding the sum (126 + 126 + 90) we can see that this ribbon is 342 inches long. To find feet we divide this by 12. To find yards, we divide it by 36.

Answer:

Each friend will receive 210.5 dollars.

Step-by-step explanation:

Total Amount Tyion has = 4,000 dollars

He wants to share evenly with 19 friends.

We need to find How much would amount each friend will receive.

We can found it by using formula:

Amount each friend received = Total Amount / Number of friends

Putting values in the formula and finding results:

Amount each friend received = 4000/19

Amount each friend received = 210.5 dollars

So, each friend will receive 210.5 dollars.

The conditional probability P(Cow | 2 legs) is 0.

We have,

To find the conditional probability of selecting a cow given that the animal has 2 legs, we need to determine the number of 2-legged animals and the number of cows with 2 legs.

From the given information, we know that cows have 4 legs.

The probability of selecting a cow with 2 legs is 0, since cows do not have 2 legs.

Thus,

The conditional probability P(Cow | 2 legs) is 0.

Answer:

This line intersects the y-axis at [tex]y = 14[/tex]

Step-by-step explanation:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope and b is the y-intercept(point where the line intersects the y-axis).

To find the slope, we take two points, and the slope is given by the change in y divided by the change in x.

In this question:

Points (-2,6) and (-4,-2). So

Change in y: -2 - 6 = -8

Change in x: -4 -(-2) = -4 + 2 = -2

Slope: [tex]m = \frac{-8}{-2} = 4[/tex]

So [tex]y = 4x + b[/tex]

Now, we take a point, and find b.

Point (-2,6), which means that when [tex]x = -2, y = 6[/tex]. So

[tex]y = 4x + b[/tex]

[tex]6 = 4(-2) + b[/tex]

[tex]b = 14[/tex]

So this line intersects the y-axis at [tex]y = 14[/tex]

Answer:

Step-by-step explanation:

Since the trapezoid is isosceles, the angles J and M are supplementary and angles M and L are congruent, therefore:

∠M = ∠L = 25*6 - 14° = 150° - 14° = 136°

Answer:

From the given figure we can see that :---

JK||ML, JK=ML and JM=KL

Therefore,

angle J+ angle L = 180°

[tex](7x + 2) + (25x - 14) = 180 \\ 32x - 12 = 180 \\ 32x = 192 \\ \boxed{x = 6}[/tex]

Now, we know that, angle M = angle L

Hence,

[tex]25x - 14 \\ =( 25 \times 6) - 14 \\ =150 - 14 \\ = \boxed{136}[/tex]

Answer:

She will jog and lift weights on the same day in 10 days

Step-by-step explanation:

To find when two events will happen on the same day, we find the least common multiple(that is not 0) of their frequencies.

In this question:

Every two days she jogs

Every 5 days she lifts.

Multiples of 2: {0, 2, 4, 6, 8, 10, 12, ...}

Multipled of 5: {0, 5, 10, 15, ...}

The least common multiple is 10, so:

She will jog and lift weights on the same day in 10 days

The value that would result in a system of equations with infinitely many solutions is -10

The system of equations is given as:

2y – 4x =

Complete the blank using h.

So, we have:

2y – 4x = h

Make y the subject

2y = 4x + h

Divide through by 2

y = 2x + h/2

By comparing y = 2x + h/2 and y = 2x – 5, we have:

h/2 = -5

Multiply by 2

h = -10

Hence, the value is -10

Answer: NEED PICTURE TO ANSWER, we dont know if it a square or if its a rectangle, sry

Step-by-step explanation:

Answer:

There will be $634.05 in the account.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

$390 in an account paying an interest rate of 2.7% compounded daily.

This means that [tex]P = 390, r = 0.027, n = 365[/tex]

Assuming no deposits or withdrawals are made, how much money, to the nearest cent, would be in the account after 18 years?

This is A(18). So

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

[tex]A(18) = 390(1 + \frac{0.027}{365})^{365*18}[/tex]

[tex]A(18) = 634.05[/tex]

There will be $634.05 in the account.
