184.8 calories :)

the grams are both 100, meaning we can use percentages. banana: 70% of 86 (.7*86=?) is 60.2 calories. yogurt: 140% of 89 (1.4*89=?) is 124.6 calories. 60.2+124.6=184.8 calories

For the spinner above, the probability of landing on black is 1/2, and the probability of landing on red is 1/3. Suppose it is s

saul85 [17]

Answer:

d) The probability spinner will land on black all three times is 1/8

Step-by-step explanation:

The probability of landing on black = 1/2

The probability of landing on red = 1/3.

Now, if the spinner is spun 3 times.

The probability it will land on black all three times

= $\textrm{ (The probability of landing on black)}^3$

= $\frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} = \frac{1}{2 \times 2 \times 2 } = \frac{1}{8}$

Hence, the probability spinner will land on black all three times is 1/8.

The height of a triangle is 8ft greater than the base. The area of the triangle is 136.5 square ft. Find the length of the base

mixer [17]

Answer:

the base is 9/2 ft and the height is 9/2 + 8, or 25/8, ft.

Step-by-step explanation:

Note that the formula for the area of a triangle is A = (1/2)(base)(height). Let's abbreviate that to A = (1/2)(b)(h). We are told that h = b + 8.

Then A = 136.5 = (1/2)(b)(b + 8), or

(after multiplying both sides by 2)

A = 273 = b^2 + 8b

which, when put into standard quadratic form, becomes:

b^2 + 8b - 273 = 0

The coefficients of this quadratic are a = 1, b = 8 and c = -273.

Thus, the discriminant is b^2 - 4ac, or 64 - 4(1)(-273) = 1156 = 17^2.

The roots are then

-8 ± √1156 -8 ± 17

x = -------------------- = ------------ = 9/2 and -25/2

2 2

Only the root 9/2 makes sense here, because measurements of length are positive.

Thus, the base is 9/2 ft and the height is 9/2 + 8, or 25/8, ft.
