A cookie recipe calls for 1 2/3 of sugar if you plan on changing the recipe to make it 2 1/2 times as much how many cups of suga

Dimas [21]

Answer:

$4\frac{1}{6}\ cups$

Step-by-step explanation:

we know that

The recipe calls for 1 2/3 of sugar

To make 2 1/2 times the recipe

Multiply 2 1/2 by 1 2/3

Convert mixed numbers to an improper fraction

$1\frac{2}{3}=\frac{1*3+2}{3}=\frac{5}{3}\ cups$

$2\frac{1}{2}=\frac{2*2+1}{2}=\frac{5}{2}$

$\frac{5}{2}(\frac{5}{3})=\frac{25}{6}\ cups$

Convert to mixed number

$\frac{25}{6}=\frac{24}{6}+\frac{1}{6}=4\frac{1}{6}\ cups$

There are 26 prize tickets in a bowl, labeled A to Z. What is the probability that a prize ticket with a vowel will be chosen, n

AfilCa [17]

The probability that a prize ticket with a vowel will be chosen, not replaced, and then another prize ticket with a vowel will be chosen is 0.031 or 3.1%. The events are dependent events.

Given that there are five vowels, which come from the letters A, E, I, O, and U, the likelihood of drawing a vowel is:

5/26

since there are a total of 26 alternatives available. After choosing that, we are left with 25 alternatives, 4 of which are vowels, thus the probability is:

4/25

The final likelihood is thus:

5/26 * (4/25) = 0.031

In other words, the likelihood is 3.1% when choosing a vowel and then another (without replacement).

The first event has an impact on the second event since there are fewer vowels and overall possibilities, hence the events are dependent.

How do I solve this? 408=1/2(b)(17)

seropon [69]

Answer:

Step-by-step explanation:

Given: $408 = \frac{1}{2} \times (b) \times (17)$

Now, solving it.

We first open parenthesis which is (b) $\times$ (17) = $17b$

Next Multiply both side by 2

⇒ 816 = $17b$

Now, we will divide both side by 17

∴ b $= 48$

Find the value of X

vredina [299]

Answer:

x=8

RPS = 36

Step-by-step explanation:

QPS = 180

The two angles that form QPS

QPR + RPS = 180

7x+88 + 3x+12 = 180

Combine like terms

10x+100 =180

Subtract 100 from each side

10x = 180-100

10x = 80

Divide by 10

x =80/10

x = 8

RPS = 3x+12

= 3(8)+12

24+12
