Length of the radius of the small pizza = 15 inches

Circumference of the small pizza :

=\tt 2\pi r

= \tt2 \times 3.14 \times 15

= \tt94.2 \: inches

Thus, the circumference of the small pizza = 94.2 inches

Length of the radius of the large pizza = 24 inches

Circumference of the large pizza :

= \tt2\pi r

\tt2 \times 3.14 \times 24

= \tt150.72

Thus, the circumference of the large pizza = 150.72 inches

Ratio of the circumferences of the two pizzas :

= 94.2 : 150.72

=  \tt\frac{94.2 \times 100}{150.72 \times 100}

= \tt \frac{9420}{15072}

Let us simplify the fraction :

=  \tt\frac{9420}{15072}

=\tt \frac{9420 \div 12}{15072 \div 12}

= \tt \frac{785}{1256}

=  \tt\frac{785 \div 157}{1256 \div 157}

= \color{plum}{ \tt\frac{5}{8} }

Thus, the ratio of their circumferences = 5:8

Therefore, the ratio of the circumferences of the pizzas as a fraction = \color{plum}{ \tt\frac{5}{8} }

Answer:

25/64

Step-by-step explanation:

C=πd

find diameter:

small= 15 x 15= 225

large= 24 x 24= 576

multiply:

225 x 3.14= 706.5

576 x 3.14= 1808.64

ratio:

706.5/1808.64

reduce:

25/64

(CO 3) On average, the parts from a supplier have a mean of 97.5 inches and a standard deviation of 6.1 inches. Find the probabi
ololo11 [35]

Answer:

C. Probability is 0.90, which is inconsistent with the Empirical Rule.

Step-by-step explanation:

We have been given that on average, the parts from a supplier have a mean of 97.5 inches and a standard deviation of 6.1 inches.

First of all, we will find z-score corresponding to 87.5 and 107.5 respectively as:

z=\frac{x-\mu}{\sigma}

z=\frac{87.5-97.5}{6.1}

z=\frac{-10}{6.1}

z=-1.6393

z\approx-1.64

z=\frac{x-\mu}{\sigma}

z=\frac{107.5-97.5}{6.1}

z=\frac{10}{6.1}

z=1.6393

z\approx 1.64

Now, we need to find the probability P(-1.64.

Using property P(a, we will get:

P(-1.64

From normal distribution table, we will get:

P(-1.64

P(-1.64

P(-1.64

Since the probability is 0.90, which is inconsistent with the Empirical Rule, therefore, option C is the correct choice.

I'll just factor the above equation.

x² + 18x + 80

x² ⇒ x * x
80
can be:
1 x 80
2 x 40
4 x 20
5 x 16
8 x 10  Correct pair

(x+8)(x+10)
x(x+10) +8(x+10) ⇒ x² + 10x + 8x + 80 = x² + 18x + 80

x+8 = 0
x = -8

x+10 = 0
x = -10

x = -8

(-8)² + 18(-8) + 80 = 0
64 - 144 + 80 = 0
144 - 144 = 0
0 = 0

(-10)² + 18(-10) + 80 = 0
100 - 180 + 80 = 0
180 - 180 = 0
0 = 0

I think the algebra tiles will not be a good tool to use to factor the quadratic equation because the equation is not a perfect square quadratic equation.
