Answer:

1) 188.4 in³

2)306 in³

3)210in³

Step-by-step explanation:

1) r = 5in h = 12in

5 * 12 * 3.14

2) L = 3 W = 8.5 H = 12

3 * 8.5 * 12

3) $\frac{1}{2}$ ( B = 5 W = 7 H = 12)

.5(5 * 7 * 12)

Which set of side lengths can be used to form a right triangle

leva [86]

Answer:

14, 48, 50

Step-by-step explanation:

To check which set of side length can be used to form a right triangle we use pythagorean theorem

c^2 = a^2 + b^2

biggest side (hypotenuse is c^2)

(a) 14, 48, 50

$50^2 = 14^2 + 48^2$

2500= 196+2304

2500= 2500 that is true

(b) 30, 40, 60

$60^2 = 30^2 + 40^2$

3600= 900+ 1600

3600= 2500 that is false

$60^2 = 14^2 + 50^2$

3600= 196+2500

2500= 2196 that is false

(d) 10, 24,28

$28^2 = 10^2 + 24^2$

784=100+576

784=676 that is false

Help!! Lots of points

murzikaleks [220]

$\frac{ {5}^{2} }{ {2}^{2} } = {( \frac{5}{2}) }^{2}$
Since they are both squared.

Evaluating 5^2 and 2^2 and finding the quotient also works.

$\frac{ {5}^{2} }{ {2}^{2} } = \frac{5 \times 5}{2 \times 2} = \frac{25}{4} = 6.25\\ \frac{ {5}^{2} }{ {2}^{2} } = {( \frac{5}{2} )}^{2} = 2.5 \times 2.5 = 6.25$
The third option, "Evaluate 5^2 and 2^2 ...," and the last option, "Rewrite the expression as (5/2)^2 ...," are the correct choices.

Marty is taking piano lessons. She is going to practice every afternoon. The 1st week she practiced for 11 minutes each day. The

Answer:

$m=7w+4$

Step-by-step explanation:

Linear Modeling

It consist is setting up a linear relationship between two variables, given some experimental data. Only 2 points are needed to set up the equation of a line, but if more than 2 points are used, then the result should use statistical approaches like linear regression to find the best-fit line.

For the question at hand, Marty practices his piano lessons 11 minutes the week #1. It provides the first point (1,11). He practices 25 minutes per day on the third week. It gives us another point (3,25). This is enough to find the equation of a line. The general formula for a line, having two points (m1,w1) (m2,w2) is

$\displaystyle m-m_1=\frac{m_2-m_1}{w_2-w_1}(w-w_1)$
