Find the unknown side length x write your answer in simplest radical form
Sauron [17]

Answer:

(B)4\sqrt{37}

Step-by-step explanation:

First, we determine the height of the triangle which we label as y.

Using Pythagoras Theorem.

25^2=7^2+y^2\\y^2=25^2-7^2\\y^2=576\\y=\sqrt{576}\\y=24

In the smaller right triangle with hypotenuse, x

Base = 7-3 =4 Units

Height, y= 24 Units

Therefore, applying Pythagoras Theorem.:

x^2=24^2+4^2\\x^2=592\\x=\sqrt{592}\\ x=4\sqrt{37}

tyra has 12 2/3 cups of sugar. if r is the amount of sugar needed for one batch of cookies, the expression 12 2/3 ÷ r can be use
olga nikolaevna [1]

ANSWER

She can make 19 batches of oatmeal.

EXPLANATION

First we can change the mixed number into an improper fraction:

12\frac{2}{3}=12+\frac{2}{3}=\frac{12\cdot3}{3}+\frac{2}{3}=\frac{36}{3}+\frac{2}{3}=\frac{38}{3}

In this problem, r = 2/3. The division is:

12\frac{2}{3}\div r=\frac{38}{3}\div\frac{2}{3}

Using the KFC rule:

\frac{38}{3}\div\frac{2}{3}=\frac{38}{3}\times\frac{3}{2}

Solving we can see that the denominator of the first fraction can be simpliied with the numerator of the second fraction:

\frac{38}{3}\times\frac{3}{2}=\frac{38}{1}\times\frac{1}{2}=\frac{38}{2}=19

Tyra can make 19 batches of oatmeal with 12 2/3 cups of sugar.

Which pair of measurements is not equivalent?
Bingel [31]

Answer:

750 mm, 7.5 cm

Step-by-step explanation:

Verify each case

case a) 2.5 km, 2,500 m

we know that

1 km ------> 1.000 m

so

2.5 km=2,500 m

therefore

The pair of measurements is equivalent

case b) 750 mm, 7.5 cm

we know that

1 cm ------> 10 mm m

so

7.5 cm=75 mm

therefore

<u>The pair of measurements is not equivalent</u>

case c) 3 m, 3,000 mm

we know that

1 m ------> 1.000 mm

so

3 m=3,000 mm

therefore

The pair of measurements is equivalent

case d) 120 cm, 1.2 m

we know that

1 m ------> 100 cm

so

1.2 m=120 cm

therefore

The pair of measurements is equivalent
