Lela and Pepe are playing a video game. The ratio of Lela’s game score to Pepe's score is 2 : 5. Then Lela completes a quest and

Fed [463]

Answer: Lela's original score was 16.

Step-by-step explanation:

Alright lets get started.

Suppose Lela score was L.

Suppose Pepe score was P.

The ratio of Lela’s game score to Pepe's score is $2:5$

So the equation will be

$\frac{L}{P} = \frac{2}{5}$

Cross multiplying

$5\times L=2\times P$

$P=\frac{5\times L}{2}$ .................equation 1

Then Lela completes a quest and scores 12 bonus points. The new ratio becomes $7:10$

$\frac{L+12}{P} =\frac{7}{10}$

Cross multiplying

$10(L+12)=7P$

Plugging value of P from equation 1

$10(L+12)= 7\times\frac{5L}{2}$

$20L+240=35L$

$15L=240$

$L=16$

Hence the score of Leela originally was 16. Answer

Find the area of the rhombus. A= square units

mylen [45]

Answer: A=70 square units

Step-by-step explanation:

The area of a triangle can be found using the formula $A=\frac{1}{2} bh$

Let 5=h and 7=b

Plug in the values and solve

$A=\frac{1}{2} (7)(5)$

$A=17.5$

However, since four of these triangles make up this rhombus, we can multiply the area of one of these triangles by four to find the area of the whole rhombus.

$A=17.5*4$

$A=70$

What is a 4:1 ratio? Is it equivalent to 75% to 25%?

Ludmilka [50]

Ratios are basically:

for this much of this:theres this much of that

lets say you have 4:1 in spoons and forks.

for every 4 spoons, there is 1 fork. if there is 8 spoons there are 2 forks and so on.
The percent is 400%

if you meant 1:4 the percent would be 25%. all other rules apply.
for every 1 spoon you have 4 forks.
