12/5 = 2.4 times larger

3 x 2.4 = 7.2 inches wide

We set up fractions. The numerator was 3 (which was the width). The denominator was 5 (which was the length). We set it equal to x/12 and cross multiplied and got 7.2.

A certain food has a gluten ratio of 13mg per L of the food.what is the gluten ratio in micrograms per milliliter? PLEASE HELP M
AlekseyPX
Given:
The gluten ratio is 13 mg per L of food.

Note that
1 L = 1000 mL (milliliter)
1 mg = 10⁻³ g
1 μg = 10⁻⁶ g
Therefore
1 mg = 1000 μg

The gluten ratio is
(13  \frac{mg}{L} )*( 1000   \frac{\mu g}{mg} )*( \frac{1}{1000} \frac{L}{mL}  )=13 \frac{\mu g}{mL}

Answer:  The gluten ratio is 13 μg/mL

You have $1000 to invest in an account and need to have $1500 in one year. What interest rate would you need to have in order to
xz_007 [3.2K]
Let r be the interest rate. Then:
1000(1+r/4)^4=1500
(1+r/4)^4=1.5
ln (1+r/4)^4= ln 1.5
4 ln (1+r/4)=ln 1.5
ln (1+r/4)=0.10136627702704109549450327886609
1+r/4=e^0.10136627702704109549450327886609=1.1066819197003215924087902734403
r/4=0.1066819197003215924087902734403
r=0.42672767880128636963516109376133 or 42.67%, compounded quarterly. ☺☺☺☺

Is (1,2) the point of intersection of y=3x-1 and y=-x+3?​
Luden [163]

Answer:

yes

Step-by-step explanation:

Solving the 2 equations to find the point of intersection

y = 3x - 1 → (1)

y = - x + 3 → (2)

Since both equations express y in terms of x, equate the right sides

3x - 1 = - x + 3 ( add x to both sides )

4x - 1 = 3 ( add 1 to both sides )

4x = 4 ( divide both sides by 4 )

x = 1

Substitute x = 1 into either of the 2 equations for corresponding value of y

Substituting x = 1 in (2)

y = - 1 + 3 = 2

Thus (1, 2) is the point of intersection
