The probability that a red block is selected from a bucket is
3/8, and the probability that a blue block is selected is 2/8.
What is the probability that a red block or a blue block is
selected?
a) 1
b) 1/2
c) 5/8
d) 6/8

Answers

Answer 1

Answer:

5/8

Step-by-step explanation:

Since we don't know what the other color (s) are, all we need to do to determine the probability is add the two fractions, and that is your probability.

Answer 2

Answer:

5/8

Step-by-step explanation:

The probability of a red block shows 3/8.  This means there are 8 blocks total and only 3 of them are red.

The probability of a blue block shows 2/8.  Again there are 8 total blocks and only 2 are blue.

So the total number of blocks remains the same....8

The total of red and blue blocks is 3 + 2 = 5

So the probability would be 5/8

A tennis racket with a price of $180 is subject to a sales tax of 7%. What is the total
price of the racket?
$192.60
$187

Answers

The total price of the racket is $192.60 (first option).

What is the total price?

A tax is a compulsory amount of money that is levied by the government or an agency of the government on goods and services. A sales tax is levied on the sales of goods and services.

The total price of the racket would include the amount of tax that would be paid.

Total price = (1 + tax/100) x initial price

Total price = (1 + 7%/100) x $180

Total price = (1 + 0.07) x $180

Total price = (1,07 x $180)  

Total price = $192.60

A Spanish teacher informed her class that she would be giving 4 quizzes each month. Write an equation that shows the relationship between the number of months elapsed, x, and the total number of quizzes, y.

Answers

Answer:

y = 4x

Step-by-step explanation:

Since there are going to be four quizzes a month (x), we know that we will multiply the number of months (x) by the number of quizzes (4). However, because we don't know how many months there are, we can define the months as (x), and instead put the total (y) is equal to the number of quizzes per month (4), multiplied by the number of months (x). Out final result is

(y = 4x)

a model of a ship is made to a scale of 1:200
the surface area of the model is 7500 cm²
calculate the surface area of the ship, giving your answer in square meters

Answers

The surface area of the ship is 1500000 cm²

Scaling is used to either increase or decrease the size of a figure so as to create an image.

Given a scale of 1:200, this means that it is a scaling down (decrease in size) of the ship to create a model.

The surface area of the model is 7500 cm², hence that of the ship is:

Surface area of ship * (1 : 200) = surface area of model

Surface area of ship = surface area of model * 200 = 7500 * 200 = 1500000 cm²

The surface area of the ship is 1500000 cm²

Complementary angles are two angles whose sum = 90°

Answers

Answer:

Carros = 20

Motos = 30

Step-by-step explanation:

Carros = x

Motos = y

x + y = 50

4x + 2y = 140

x = 50 - y

4 (50-y) + 2y = 140 (substitución)

200 - 4y + 2y = 140

- 2y = 140 - 200

y = -60/-2

y = 30

x + 30 = 50

x = 50-30

x = 20

Answer:

Step-by-step explanation:

The whole angle is 180 degrees.

90 degrees is already taken by the angle dividing the two vertical angles.

So you have 90 degrees left. then you have to subtract 49 from 90 to get the angle of '5t+6'.

So 5t+6 = 41, 41-6 is 35. 35/5 is 5, so t is 5.

I didn't go too far into explaining since you asked to not explain it.

#13. line QR is 26.

#14. a) x = 2 b) m = 6

Step-by-step explanation:

13. We can use the Pythagorean therom: a^2 + b^2 = c^2

We will substitue PQ for a and PR for b

10^2 + 24^2  = c^2

100 + 576 = c^2

100 + 576 = 676

Then, we find the square root of 676, which is 26.

14. a) 3(2x -1) = 9

we first use distributive property:

6x - 3 = 9

then we add 3 to both sides to counteract the -3:

6x = 12

we divide both sides by 6 to get x alone:

x = 2

b) 3m - 12 = 6

we add 12 to both sides to counteract the -12:

3m = 18

we divide both sides by 3:

m = 6
