Answer:

Step-by-step explanation:

Yasmina:

5.25 x 5 = 26.25 per week

5.25 x 20 = 105 per month

5.25 x 260 = 1365 per year

Camila:

9.75 x 35 = $ 341.25 earnings per week

341.25 x 0.20 = 68.25 saves per week

9.75x35x 4= 1365 earnings per month

1365 x 0.20 = 273 saves per month

9.75 x 35 x 52 = 17745 earnings per year

17745 x 0.20 = 3549 saves per year

A brand of cereal had 1.2 mg of iron per serving then they change their receipt so they had 1.8 mg of iron per serving what was

Neko [114]

Answer:

$50\%$

Step-by-step explanation:

To Calculate the percentage Increase

Step 1: Subtract the old value from the new value

1.8 mg - 1.2 mg = 0.6 mg

Step 2: Divide the difference by the Old Value

$\dfrac{0.6}{1.2}$

Step 3: Multiply by 100

$\dfrac{0.6}{1.2} X 100\\=50\%$

The Percentage Increase in Iron is 50%.

When solving systems of equations with the elimination

viktelen [127]

Step-by step explanation:

That's a great question. Look for things such as these:

x=x (infinite solution)

x=12 (one solution)

x+3 = x + 5 (no solutions)

Find the value(s) of the variable(s). Write your answer(s) in simplest radical form.

Romashka [77]

Answer:

Step-by-step explanation:

12). By applying Pythagoras theorem in the given right triangle,

Hypotenuse² = (Leg 1)² + (Leg 2)²

x² = 7² + 7²

x² = 2(7)²

x = $\sqrt{2(7)^{2} }$

x = $7\sqrt{2}$

13). By sine rule,

sin(60)° = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

$\frac{\sqrt{3}}{2}=\frac{9\sqrt{3} }{y}$

y = $\frac{18\sqrt{3} }{\sqrt{3} }$

y = 18

By cosine rule,

cos(60)° = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

$\frac{1}{2}=\frac{x}{y}$

x = $\frac{y}{2}$

x = $\frac{18}{2}=9$

14). By applying Pythagoras theorem in the given right triangle,

12² = x² + x²

144 = 2x²

72 = x²

x = √72

x = 6√2
