evablogger [386]

Answer:

83 degrees

Step-by-step explanation:

vertical degrees show that angles across from one another have the same value. All three angles will add up to 180 degrees. Subtract both 56 and 41 from 180 degrees to get a remainder of 83.

Mara's family is driving to her grandmothers' house. The family travels 239.4 miles between the hours of 9:10 a.M. To 1:40 p.M.
anzhelika [568]

Answer:

53.2 mph

Step-by-step explanation:

Mara's family travels 239.4 miles between the hours of 9:10 a.m. to 1:40 p.m.

1:40 p.m. is 13:40.

Thus, they traveled for

13 hours 40 minutes - 9 hours 10 minutes = 4 hours 30 minutes

that is 4\frac{1}{2}=4.5 hours.

Use formula:

D=r\cdot t,

where

D = distance

r = rate

t = time.

In your case,

D = 239.4 miles

t = 4.5 hours

Hence,

239.4=4.5r\\ \\r=\dfrac{239.4}{4.5}=53.2\ mph

Sue has one spin of the circular spinner shown below.
VARVARA [1.3K]

Answer:

Colour | Probability

YELLOW | 0.20

WHITE | 0.18

GREEN | 0.12

RED | 0.18

BLUE | 0.32

Step-by-step explanation:

The complete question is presented on the attached image to this solution.

From the image of the spinner and the given probabilities, the combination of YELLOW, WHITE and GREEN make up exactly half of the total space on the spinner.

0.2 + 0.18 + 0.12 = 0.50

Then, BLUE and RED make up the other half of the spinner.

Probability of landing on either BLUE or RED = 1 - 0.50 = 0.50

Let P(BLUE) = x and P(RED) = y

x + y = 0.50

Two of the lines shown on the diagram are diameters of the circle.

The first line that is a diameter splits the circle into two parts; (WHITE, YELLOW, GREEN) and (RED, BLUE).

From here, we have established that x + y = 0.50

The other line that is a diameter splits The circle into two part; (WHITE, BLUE) and (YELLOW, GREEN, RED)

From this other information,

P(WHITE) + P(BLUE) = 0.50

0.18 + x = 0.50

x = 0.50 - 0.18 = 0.32

P(YELLOW) + P(GREEN) + P(RED) = 0.50

0.20 + 0.12 + y = 0.50

y = 0.50 - 0.32 = 0.18

To check, x + y = 0.32 + 0.18 = 0.50 (Correct!!)

Hope this Helps!!!

2(x -9) = 9 divided ( - 1/3) what value of x makes the equation true <br> plsss help :)))
Ivanshal [37]

Answer:

x = -9/2

Step-by-step explanation:

1. Divide 9 by -1/3:

\frac{9}{1} ÷ -\frac{1}{3} = \frac{9}{1} · -\frac{3}{1}

= -27

2. Divide both sides by 2:

2(x - 9) = -27

\frac{2(x-9)}{2} = \frac{-27}{2}

(x - 9) = -\frac{27}{2}

3. Add 9 to both sides:

x = -\frac{9}{2}

(or 4.5 if you need it in decimal form)

hope this helps!
