If the area of a triangle is 30 in.? and the base is 5 in., what is the height?

seropon [69]

The height would be 12. This is because the area formula for a triangle is base times height divided by 2.
Therefore 12 x 5 = 60 and 60/2 = 30 :)

Williiam lost 25% of his marble,gave 1/6 of the remainder to his.Brother and had 120 marbles left.How many marbles did he have a

bija089 [108]

Answer:

Number of marbles with Williams at the starting = 192

Step-by-step explanation:

Let total number of marbles with Williams = m

He lost marbles = 25% of the total number

= $\frac{25}{100}\times m$

= $\frac{m}{4}$

Remaining marbles with Williams = m - $\frac{m}{4}$

= $\frac{3m}{4}$

He gave marbles to his brother = $\frac{1}{6}$ th of the remaining marbles

= $\frac{1}{6}\times \frac{3m}{4}$

= $\frac{m}{8}$

Remaining marbles after giving marbles to his brother = 120

Therefore, $\frac{3m}{4}-\frac{m}{8}=120$

$\frac{6m}{8}-\frac{m}{8}=120$

$\frac{5m}{8}=120$

m = $\frac{120\times 8}{5}$

m = 192

Number of marbles with Williams at the starting = 192

Answer:

5.3 hours

Step-by-step explanation:

Given:

3 hours = 8lbs. turkey

?? hours = 14lbs. turkey

Do proportions:

$\frac{3}{8}$ = $\frac{x}{14}$ <-- Cross Multiply

42 = 8x <-- Solve for x

x = 5.25

Round to the nearest tenth:

x = 5.3 hours
