Answer:

#1 THE LENGTH IS 24 FT, WIDTH IS 12 FT..... #2 DISTANCE IS 7

Step-by-step explanation:

ON PROBLEM ONE ITS SAYING FOR EVERY 1 CM ITS EQUALY TO 4 FEET, SO MULTIPLY 6CM*4 FEET OR 1*4 + 1*4 + 1*4 + 1*4 + 1*4 +1*4=24

YOU DO THE SAME FOR THE WIDTH WHICH WOULD BE 3CM*4FT=12

ITS THE SAME FOR THE SECOND PROBLEM TO YOUD DO 2*3 1/2=7

Step-by-step explanation:

I'm going to answer number one.

The figure you are given is a scale copy- a smaller version of the real thing with the same ratio of measurements. So, since we have a 6cm length and 1 cm is supposed to be 4 feet, multiply 6 by 4 to get 24 feet as the real length.

We have 3 cm as width, so multiply that by 4 to get 12 feet as the real width

Finding area of shaded sectors.

tekilochka [14]

Answer:

69.81 sq. m. (rounded to 2 decimal places)

Step-by-step explanation:

The sector of a circle is "part" or "portion" of a circle. The formula for the area of a sector is:

$A=\frac{\theta}{360}*\pi r^2$

Where

$\theta$ is the central angle

r is the radius

Given the figure, the arc is given as 80 degrees, but not the central angle of the shaded sector. But from geometry we know that the central angle and the intercepted arc have the same measure. So we can say:

$\theta = 80$

Also, the radius of the circle shown is 10 meters, so

r = 10

Now, we substitute in formula and find our answer:

$A=\frac{\theta}{360}*\pi r^2\\A=\frac{80}{360}*\pi (10)^2\\A=\frac{2}{9}*100\pi\\A=\frac{200\pi}{9}\\A=69.81$

Thus,

The area of the shaded sector is 69.81 sq. meters.

Given that XY is a line segment with the angle a = 48° and c = 59°, work out the value of the angle marked b.

olga nikolaevna [1]

Answer:

a+b+c = 180

48+59+b=180

107+b=180

b=180-107

b=73

The square of a number minus six times a number equals negative five.

olga_2 [115]

Answer:

x² - 6x = -5

x = {1, 5}

Step-by-step explanation:

The square of a number minus six times a number equals negative five.

x² - 6x = -5

Add 5 to both sides

x² - 6x + 5 = 0

Factor

(x - 1)(x - 5) = 0

x = {1, 5}

Find the probability that the hitter makes 10 outs in 10 consecutive at-bats, assuming at-bats are independent events. Hint:

emmainna [20.7K]

Answer:

0.037

Step-by-step explanation:

If the hitter makes an out 72% of the time, then the probabilty that he makes hit in 1 at-bat is $p=0.72$ and the probabilty that he doesn't make hit in 1 at-bat is $q=1-p=1-0.72=0.28.$

The probability that the hitter makes 10 outs in 10 consecutive at-bats, assuming at-bats are independent events is

$P=p^{10}=(0.72)^{10}\approx 0.037.$
