Answer:

Step-by-step explanation:

You divide the diameter by 2 to get radius. So 5÷2=2.5

So then you multiply 2.5 by pi aka 3.14 so 2.5x3.14=7.85 So we rounds 7.85 to 7.9

The formula W=0.86g^2-0.01g+5.9 models the weight, W, in ounces, for a cat who is fed g grams per day of a special food. Accordi

RUDIKE [14]

Using the equation which models weight of cat in terms of amount of food fed, the weight of the cat will be : 151.11 ounces

Given the equation :

W=0.86g² - 0.01g +5.9

g = Amount of food in grams

Substituting g = 13 into the equation :

W = 0.86(13)² - 0.01(13) +5.9

W = 0.86(169) - 0.13 + 5.9

W = 145.34 - 0.13 + 5.9

W = 151.11 ounces

Therefore, the weight of the cat will be 151.11 ounces

Find the value of X, Z, and Y in the graph below?

ella [17]

9514 1404 393

Answer:

(x, y, z) = (49, 58, 122)

Step-by-step explanation:

The same-side exterior angles have a sum of 180°.

(x +9) +(3x -25) = 180

4x -16 = 180

x -4 = 45

x = 49

Vertical angles are congruent:

y = 49 +9 = 58

z = 180 -y = 122 = 3(49) -25

The values of x, y, and z are ...

X = 49
Z = 122
Y = 58

!!!PLEASE HELP ASAP!!! I WILL GIVE MORR POINTS IF NEEDED AND MARK BRAINLIEST

The first one shows 1 cm and 7 mm, we need to convert 7 mm to cm
1 cm + 7 mm
= 1 cm + $\frac{7}{10}$ cm
= 1 cm + 0.7 cm
= 1.7 cm
The first one is 1.7 cm

The second one shows 11 inches and 5/16 inches. Between number 11 and 12, there are 16 strips and the pointer lies on fifth strip, thus it show 5/16 inches. The second one is 11 $\frac{5}{16}$ inches.

The third one shows 13 cm and 8 mm. We need to convert mm into cm.
13 cm + 8 mm
= 13 cm + 0.8 cm
= 13.8 cm
The third one is 13.8 mm
