Every day, Isabella practices the piano for 0.75 hour and the flute for 1.4 hours. What is the total number of hours that she practiced in April? (Reminder: April has 30 days

Answers

Answer:

She practiced a total of 64.5 hours

Step-by-step explanation:

Here, we need to know the number of hours practiced on both per day

Mathematically, that will be;

0.75 + 1.4 = 2.15 hours per day

So in 30 days ; the total number of hours will be

30 * 2.15 = 64.5 hours

The ratio of the number of cars to dolls in a toy store is 3/20 . The ratio of the number of male dolls to the number of female dolls is 3:5 There are 500 female dolls. How many toys are there?

Answers

Answer:

800 dolls

Step-by-step explanation:

Step one:

given  data

we are told that the ratio of the number of male dolls to the number of female dolls is 3:5 , i.e male dolls to female dolls is 3 to 5

given that there are 500 female dolls, let the number of male dolls be x

Step two:

3/5= x/500

cross multiply we have

3*500=5x

1500=5x

divide both sides by 5

x=1500/5

x=300

hence there are 300 male dolls

The total dolls is 300+500= 800 dolls

Dimas is playing a game that uses a number cube. The sides of the cube are labeled from 1 to 6. Dimas wants to roll a 2 or 3. He rolls the number cube one time

Answers

Answer:

B. 1/3

Step-by-step explanation:

The total number of sides in the cube are 6 (1,2,3,4,5,6). If Dimas only wants to roll either a 2 or 3 then that would mean that he has 2 chances out of the total 6 probable outcomes to roll one of those numbers. Therefore, in order to find the probability of this happening in a single roll we need to divide the number of times that his two choices appear on the dice by the total number of sides the dice has, like so...

2 / 6 = x

Find the value of x that makes m || n

Answers

Answer:

a) 24

Step-by-step explanation:

To  make m//n,  the sum of co-interior angles (4x + 84) should be 180

4x + 84 = 180

        4x = 180 - 84

        4x = 96

         x = 96/4

        x = 24

The graph below shows a system of equations:

The x-coordinate of the solution to the system of equations is

Answers

Answer:

solution is (-2, 2) so x-coordinate of solution is -2

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

First, we have to write down both equations.

y = x + 4

3y = -2x + 2

Now we already have an equation that we can plug into the other equation.

= 3(x + 4) = -2x + 2

= 3x + 12 = -2x + 2

= 5x + 12 = 2

= 5x = -10

x = -2

Now we know that x = -2, and the question asks for the x-coordinate, which is -2.

Find the solution of this system of equations
x- 10y = -59
-4x + 10y = 86

Answers

Answer:

x - 10y = -59

(+)-4x + 10y = 86

-3x = 27

x = -9

substitute x into x - 10y = -59

-9 -10y = -59

-10y = -50

y = 5

a) The average high and low temperatures are -8°C and -27°C.  b) The average high and low temperatures are 13°C and  7°C. c) The average net change in temperature is -19°C.  d) The average net change in temperature is 6°C.  e) Nuuk in January experiences a larger absolute change.  f) The January low for Nuuk is 3.8 times farther below the freezing point of water than the August low for Isla Hoste.

Part A

The average high temperature in Nuuk in January is -8°C and the average low temperature is -27°C.

Part B

The average high temperature in Isla Hoste in August is 13°C and the average low temperature is 7°C.

Part C

The average net change in temperature in Nuuk in January is -27°C - (-8°C) = -19°C.

Part D

The average net change in temperature in Isla Hoste in August is 13°C - 7°C = 6°C.

Part E

Nuuk in January experiences a larger absolute change between the high temperature and low temperature, with a net change of -19°C, compared to Isla Hoste in August, with a net change of 6°C.

Part F

The January low for Nuuk is -27°C, which is 27°C below the freezing point of water. The August low for Isla Hoste is 7°C, which is 7°C below the freezing point of water. Therefore, the January low for Nuuk is 27 / 7 = 3.8 times farther below the freezing point of water than the August low for Isla Hoste.
