Answer:

C. The roller coaster is 150 feet.

Step-by-step explanation:

If Kate casts a 2-ft shadow, and the rollercoaster casts a 60-ft shadow, and Kate is 5 feet tall, that means for every 5 feet, the shadow is 2-ft more. Which means every foot of shadow is equal to 2.5 ft in real life.

60 x 2.5 = 150

I hope that this helps! :)

A flat screen television has a 50 inch diagonal and a height of 25 inches. How wide is the television rounded to the nearest ten

Lyrx [107]

Answer: 43.3 inches.

Step-by-step explanation:

According to the Pythagorean Theorem:

$a^2=b^2+c^2$

Where "a" is the hypotenuse, and "b" and "c" are the legs of the right triangle.

Let be "c" the width of the television.

We can indentify in the figure that:

$a=50in\\b=25in$

Then, we can substitute values and solve for "c":

$(50in)^2=(25in)^2+c^2\\\\c=\sqrt{(50in)^2-(25in)^2}\\\\c=43.30in$

Rounded to the nearest tenth:

$c=43.3in$

The recipe for cereal squares uses the ratio 20 large marshmallows to 3 cups of cereal. The ratio of mini-marshmallows to large

Nadya [2.5K]

The relationships are:

20 large marshmallows = 3 cups cereal

3 mini marshmallows = 1 large marshmallow

Therefore if there are 6 cups cereal, so we also get 40 large marshmallows. Since for every 1 large, we need 3 mini, hence:

mini marshmallows = 40 * 3 = 120

Convert the following equation into<br> standard form.

kicyunya [14]

Answer:

7x+9y=45

Step-by-step explanation:

Standard equations always mean that you have to get x and y on one side so that they equal the coefficient.

Do this by adding the fraction that is combined with x to the other side where y is. The equation should now read $\frac{7}{9} x + y = 5$

Standard form cannot have fractions, so now you must multiply by the denominator (9) on both sides of the equation in order to cancel it out. Don't forget to multiply EACH variable by 9. This leads you to the answer.
