Vinnie decorated 72 cookies in 36 minutes how many cookies did he decorate per minute

2 answers:

5 0

You need to find the unit rate( how many cookies decorated per 1 minute) so you'd divide 72 cookies by 36 minutes to result in 2 cookies per 1 minute, or 2/1.

The circumference of the hub cap of a tire is 83.21 centimeters. Find the area of this hub cap. Use

Elena L [17]

Answer:

<u>551 square centimeters</u>

Step-by-step explanation:

Finding the radius (r) :

C = 2πr
83.21 = 2 x 3.14 x r
83.21 = 6.28r
r = 83.21/6.28
r = 13.25 cm

Finding the area :

A = πr²
A = 3.14 x (13.25)²
A = 3.14 x 175.5625
A = <u>551 square centimeters</u> (nearest whole number)

<u></u>

The area of this hub cap is about <u>551 square centimeters</u>.

According to the general equation for conditional probability, if P(A upside down u B)= 5/7 and P(B)=7/8 , what is P(A|B)?

natta225 [31]

$P(A | B) = \frac{P(A \cap B)}{P(B)}$

$P(A|B) = \frac{5/7}{7/8}$

$P(A|B) = \frac{5}{7} \div \frac{7}{8}$

$P(A|B) = \frac{5}{7}\times\frac{8}{7}$

$P(A|B) = \frac{5*8}{7*7}$

$P(A|B) = \frac{40}{49}$

The ratio of the angles in a triangle is 5:9:10. what is the measure of the largest angle?

Maksim231197 [3]

The measure of the largest angle is 75 degrees.

<h3>What is a triangle? </h3>

A triangle is a polygon with three sides and vertices. The sum of angles in a triangle is 180 degrees. Types of triangles include: right-angled triangle, isosceles triangle, equilateral triangle and scalene triangle.

<h3>What is the measure of the largest angle? </h3>

The measure of the largest angle = (largest ratio / sum of ratios) x 180

10 / 24 x 180 = 75 degrees
