Raymond normally has a snack consisting of ten 12-calorie crackers. How many 20-calorie cookies would he have to eat to consume

ss7ja [257]

<h3>Answer: 6</h3>

Work Shown:

He eats ten 12-calorie crackers, so that is 10*12 = 120 calories total

If x is the number of 20-calorie cookies, then the total number of calories here is 20x. We want this to be 120, so,

20x = 120

x = 120/20 .... divide both sides by 20

x = 6

He must eat six 20-calorie cookies to get 120 calories total

A scale model of a street sign is in the shape of a triangle. The base is 4.25 cm and the height is 8.8 cm what is the area of t

agasfer [191]

Answer:

18.7 cm²

Step-by-step explanation:

To work out the area of a triangle you have to use the formula

$\frac{1}{2} * B * H$

Where "B" is the base and "H" is the height

Since these are decimals, I like to convert them into fractions which makes them easier to calculate with

The base is 4.25 cm which will turn into $4\frac{1}{4}$

The height is 8.8 cm which will turn into $8\frac{8}{10}$

Now we use the formula

$\frac{1}{2} * B * H$

$\frac{1}{2} * 4\frac{1}{4} *8\frac{8}{10}$

→ Convert to improper fractions

$\frac{1}{2} * \frac{17}{4} *\frac{88}{10}$

→ Simplify

$\frac{187}{10}$

→ Convert into decimal
