What is the m ZACB? 10° 50° 90° 180°

Mathematics
1 answer:
kifflom [539]3 years ago
7 0

Answer:

50 deg

Step-by-step explanation:

In an right triangle, the acute angles are complementary. That means their measures have a sum of 90 deg.

m<C + m<B = 90

7x - 20 + 4x = 90

11x = 110

x = 10

m<ACB= 7x - 20

m<ACB = 7(10) - 20

m<ACB = 70 - 20

m<ACB = 50

Answer: m<ACB = 50 deg

At a local restaurant, a couple ordered two dinners for $12.50 each and two drinks for $1.50 each. If the couple left an 18% tip
aivan3 [116]
First, you have to add up the cost of each meal and drink:
12.50 + 12.50 + 1.50 + 1.50 = 28


$28 is the cost before the tip. Now multiple 28 by .18 to find the tip:
28 x .18 = 5.04

The tip was $5.04. Add the 28 and the 5.04 to get the total cost:
28 + 5.04 = 33.04

ANSWER:
The total cost was $33.04

When 50 mL of water is added, the graduated cylinder has a mass of 180 g. If a rook is added to the graduated cylinder, the wate
Bezzdna [24]

Answer:

2.25 (or \frac{9}{4}) g/mL

<u>Skills needed: Density</u>

Step-by-step explanation:

1) Briefly, let's cover what density is:

- It is \frac{mass}{volume}

- Measures the mass per unit of volume

- In this situation the formula for density is: \frac{m_f-m_i}{v_f-v_i}

---> m_f is the final mass

---> m_i is the initial mass

---> v_f is the final volume

---> v_i is the initial volume

2) In this case, we start out with a mass of 180 grams as stated in the problem, and also 50 mL of water initially.

This means that:

- m_i is 180 g

- v_i is 50 mL

3) Also, we end up with 270 g in mass, and 90 mL of water finally.

- m_f is 270g

- v_f is 90 mL

4) We can find density by substitute given the values above:

\frac{270-180}{90-50} = \frac{90}{40} = \frac{9}{4} \text{ or } 2.25

5) Our answer is 2.25 g/mL (since mass is grams (g), and volume is milliliters (mL) in the problem above).
