B stands for the area of the triangular base of the prism.

Area of a triangle = hb/2
h = height of the triangle = 3.75cm
b = base of the triangle = 28mm convert to cm. 2.8 cm

Area of a triangle = (3.75cm * 2.8cm) /2 = 10.5 cm² / 2 = 5.25 cm²

The value of B is 5.25 cm²

A bag of gumballs contains 2 pink, 3 orange, 4 blue, 2 red,

vesna_86 [32]

Answer:

1/33

Explanation:

1. Sample space

The total number of gums is 2 + 3 + 4 + 2 + 1 = 12.

The number of different outcomes, i.e. the size of the sample space, for the selection of two gumballs from 12 gums is 12 × 11 = 132 different combinations.

2. Number of combinations for the desired outocome.

There are four possible combinations in which one ball is pink and one is yellow:

first is yellow and second is one of the pinks
first is yellow and second is the other pink
first is one of the pinks and second is yellow
first is the other pink and second is yellow

3. Probability

By definition:

Probability = number of favorable outcomes / total number of outcomes

Therefore:

Probability that Pierre selects a yellow and a pink gumball = 4/132

Probability that Pierre selects a yellow and a pink gumball = 1/33

A recipe calls for 3/4 cup of butter. Angie wants to triple the recipe, but she has only 1 5/8.

Lyrx [107]

Let's start out by tripling the original recipe to see how much butter Angie needs.

$\frac{3}{4} * 3 = total$
$\frac{3* 3}{4} = total$
$\frac{9}{4} = total$
$2 \frac{1}{4} = total$

So we need $2 \frac{1}{4}$ cups of butter, but Angie only has $1 \frac{5}{8}$ . Let's subtract what Angie has from the total to see how much more she needs.

$2 \frac{1}{4} - 1\frac{5}{8} = n$
$\frac{9}{4} - \frac{13}{8} = n$
we will need the least common denominator for both fractions
$\frac{2}{2} *(\frac{9}{4}) - \frac{13}{8} = n$
$\frac{18}{8} - \frac{13}{8} = n$
$\frac{5}{8} = n$

So Angie need $\frac{5}{8}$ cups more of butter for the recipe.
