Jason considered two similar televisions at a local electronics store. The generic version was based on the brand name and was three fourths the size of the brand name. If the generic television set is 12 inches by 24 inches, what are the dimensions of the brand name television?

Answers

Answer 1

Answer:

Answer: The dimensions of brand name will be

16 inches by 32 inches.

Step-by-step explanation:

Since we have given that

Dimensions of generic version is given by

$12\text{ inches }* 24\text{ inches }$

Since we have also given that

$Generic=(3)/(4)* \text{brand }$

So, we first use the 12 inches

$12=(3)/(4)* \text{ brand}\n\n12* (4)/(3)=brand\n\n16\text{ inches}=brand$

Similarly,

if we now use the dimension 24 inches

$24=(3)/(4)* \text{ brand}\n\n24* (4)/(3)=brand\n\n32\text{ inches}=brand$

so, the dimensions of brand name will be

16 inches by 32 inches.

Answer 2

Answer: 12*4/3 = 16
24*4/3= 32

What is division?

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

Let x = the jujubes Sam had

he gave x/2 to jen

jen eats half of it = 1/2(x/2)

= x/4

the remaining x/4 he gave to kyle

kyle kept 8 and gave 10 to Kim

x/4 - 8 = 10

x/4 = 18

x =72

so, we get,

thus jen had 36 jujubes

jen eat 18 jujubes

Hence, The solution is, jen eat 18 jujubes.

Let x = the # jujubes Sam had
he gave x/2 to jen
jen eats half of it = 1/2(x/2) = x/4
the remaining x/4 he gave to kyle
kyle kept 8 and gave 10 to Kim
so
   x/4 - 8 = 10
   x/4 = 18
   x =72
thus jen had 36 jujubes
jen eat 18 jujubes

Ninety students auditioned for the school play. One-third of those who auditioned were cast, 6 in major roles. What fraction of those who were cast got major roles?

Answers

Answer:

Step-by-step explanation:

0.2

Total number of students: 90

Total number of students who were cast: 1/3 x x 90 = 30

Number of students who got a major role: 6

Fraction of students who got a major role: 6/30

Fraction of students who got a major role: 1/5

1/5 as a decimal is 0.2

So in conclusion, the fraction of students who were cast and got major roles is 1/5 and the answer as a decimal is 0.2!

How do you simply 2x+8=-6

Answers

To simplify 2x + 8 = -6, the easiest way is to manipulate the equation one step at a time:

2x + 8 = -6
2x = -14 (subtract 8 from both sides)
x = -7 (divide both sides by 2)

There are 420 children in a school. 45% of the pupils are boys. How many boys are there?
How many girls are there?

Answers

$1 \% = (1)/(100) \n \n 45 \% =(45)/(100)=(9)/(20)\n \n total \ children : 420 \n \n boys : \n \n420 \cdot 45 \% = 420 \cdot (9)/(20)= 21\cdot 9 =189 \n \n girls : \ \n \n 420 -189 = 231$

total children = 420
boys = 45% of 420 = 189 boys
Girls = (100-45)% = 55% of 420 = 231 boys

a new gym is being built at greenfield middle school. The length of the Gym is 12 inches on the builders blueprint. Find the actual length of the gym if the scale is 3/4 in = 5ft

Answers

Using scale conversion in mathematics, we set up a proportion based on the blueprint scale of 3/4 in equals 5 ft. Solving this proportion, we find the actual length of the gym is 80 feet.

In mathematics, this problem is about scale conversion.

The blueprint scale in this case is 3/4 in equals 5 ft.

To find out the actual length of the gym, we need to set up a proportion and solve for the missing value.

We know that 3/4 inches represents 5 feet on the actual gym.

According to the blueprint, the length of the gym is 12 inches.

First, let's set up the proportion: 3/4 in: 5 ft = 12 in: x ft.

Now we can cross multiply and solve for 'x'. (3/4) * x = 12 * 5, which simplifies to (3x/4) = 60.

Multiply both sides by 4 to isolate 'x': 3x = 240.

Finally, divide both sides by 3, we get x = 80.

Therefore, the actual length of the gym is 80 feet.
