Answer:

1. 14

2. 10

3. 4

Step-by-step explanation:

(You have very organized tabs, much neater than mine)

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

1. Basically just count the squares from the home to the school using the blue path.

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

2. You must use the pythagorean theorem for this, the formula is:

a² + b² = c²

One side is 6, the other is 8, so:

36 + 64 = 100

$\sqrt{100}$ = 10

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

To find how much longer something is, you minus:

14 - 10 = 4

Katie works part-time at a Fallbrook riding stable she makes $5 an hour for exercising horses and $10 an hour for cleaning stall

Nookie1986 [14]

In order to at least earn $90, Katie can work exercising horses for 6 hours and cleaning stalls for 6 hours.

Step-by-step explanation:

Let hours of exercising horses be x --> $5 per hour = 5x

Let hours of cleaning stalls be y --> $10 per hour = 10y

Total earning = $\geq 90$

Total hours = 12

Equation 1:

5x + 10y = $\geq 90$

Equation 2:

x + y $\leq 12$

1. Multiply equation 2 by -5

x + y $\leq 12$ (*-5)

5x + 10y = $\geq 90$

-5x - 5y $\leq -60$

5x + 10y = $\geq 90$

2. Solve

-5x + 5x -5y + 10y = -60 + 90

5y = 30

y = 6

x + y = 12

x + 6 = 12

x = 6

Therefore, in order to at least earn $90, Katie can work exercising horses for 6 hours and cleaning stalls for 6 hours.

What's 14 ten thousands + 12 thousand

statuscvo [17]

The answer to this question would be 152,000

In this question, you are given multiple number names and asked to add it. To answer this question, it will be easier to split the sentences into multiple parts like this:
1. "14 ten thousands" mean 14 * 10,000 =140,000
2. "12 thousands" mean 12 * 1,000= 12,000
Then, if you add them up it will be: 140,000+ 12,000= 152,000
