Answer:

h = 6

Step-by-step explanation:

Substitute the given to its corresponding places.

30 = \frac{1(10)h}{2}

30 = 10h/2

Multiply both sides by two to remove the denominator.

2 [30 = 10h/2] 2

60 = 10h

Divide both sides by 10 to isolate h.

h = 6

To check, substitute everything to the original equation:

A = \frac{1(10)(6)}{2}

A = 30 !

k0ka [10]

1. The system of inequality is

y < 1.5x - 3

y < -2x/3 + 4



2. A is (2,-3)

E is (3,1)

-3 < 1.5(2) - 4

-3 < -1

1 < -2(3)/3 + 4

1 < 2



3. You can graph the inequality and see which schools inside the zone. Schools C and B are the schools he is allowed to attend.

Of a squirrel's hidden nuts, for every 5 that get found, there are 3 that do not get found. A squirrel hid 40 nuts all together.
koban [17]

Answer:

15 nuts do not get found.

Step-by-step explanation:

Given that Of a squirrel's hidden nuts, for every 5 that get found, there are 3 that do not get found.

Total number of nuts squirrel had hidden = 40

Proportion of nuts not found to total = 3/(3+5) = 3/8

Hence out of 40, nuts not found =3/8(40) = 15 nuts.

15 nuts would not be found and 25 nuts would be found if squirrel had hidden in total 40 nuts.

This is because the proportion of found:unfound = 5:3

Hence 25:!5 =5:3 satisfies this

15 nuts are not found.

2 1/4 x2 1/4 in mixed number
maks197457 [2]

Answer:

5 \frac{1}{16} is the answer.

Step-by-step explanation:

Given:

2 \frac{1}{4} \times 2 \frac{1}{4}

<u>Step 1: Converting the mixed fraction into  fraction:</u>

Multiply  4 by 2 add  1 to the result.

<u></u>2\frac{1}{4}  =  \frac{4 \times 2+1}{4}

=\frac{8+1}{4}

=\frac{9}{4}

<u>Step 2: Performing the multiplication using the fraction</u>

= >\frac{9}{4} \times \frac{9}{4}

=> \frac{81}{16}

<u>Step 3: Converting the product back to  mixed fraction </u>

divide 81 by 16 and find the remainder

=>quotient \frac{remainder}{divisor}

Dividing 81 by 16 we get  5 as quotient and 1 as remainder

Thus the result in  mixed fraction will be

=> 5 \frac{1}{16}
