Answer:

On the blueprint the dimensions are <u>48 inches by 64 inches</u>.

Step-by-step explanation:

Given:

The scale on blueprint was 1/4 inch = 1 foot.

The actual dimensions of her bedroom are 12 feet by 16 feet.

Now, to find the dimensions on the blueprint.

Let the dimensions on the blueprint be x by y.

As, given the scale on blueprint:

\frac{1}{4}\ inch=1\ foot

So, \frac{1}{4}\ inch  is equivalent to 1 foot.

Thus, x is equivalent to 12 feet.

And, y is equivalent to 16 feet.

Now, solving by cross multiplication method:

\frac{\frac{1}{4}}{1} = \frac{x}{12}

\frac{4}{1} =\frac{x}{12}

<em>By cross multiplying we get:</em>

48=x

x=48\ inches.

Now, again:

\frac{\frac{1}{4}}{1} =\frac{y}{16}

\frac{4}{1} =\frac{y}{16}

<em>By cross multiplying we get:</em>

64=y

y=64\ inches.

Therefore, on the blueprint the dimensions are 48 inches by 64 inches.

Answer:

Factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12. A positive integer greater than 1, or an algebraic expression, that has only two factors (i.e., itself and 1) is termed prime; a positive integer or an algebraic expression that has more than two factors is termed composite. The prime factors of a number or an algebraic expression are those factors which are prime. By the fundamental theorem of arithmetic, except for the order in which the prime factors are written, every whole number larger than 1 can be uniquely expressed as the product of its prime factors; for example, 60 can be written as the product 2·2·3·5.

Jimmy cn run 3.5 miles in 20 minutes. How far can he run in one hour and ten minutes?
vladimir2022 [97]

Answer: 12.25miles.

Step-by-step explanation:

This is a simple proportion.

                       20 miles   = 3.5miles

      ∴                1 mile     = 3.5/20

      ∴  1hour 10minutes  which is equivalent to 70minutes will be

                                        =  (3.5/20 x ⁷⁰/₁ ) miles

                                        = 12.25miles
