A recipe that makes 4 servings calls for Two-thirds cup of flour. How much flour is required to make 20 servings?

Explain how you decide which part of a problem will be represented by the variable x, and which part will be represented by the

Well i don't know if this will help but slope intercept form

y=mx+b

M-slope
B-Y intercept
and
(x,y)- would be any point on the graph and if you were to plug those points in for x and y the equation would solve if done properly

Need help can someone plz help me solved this problem ASAP! Need help I will mark you as brainiest

Answer: 24, 33

2.5, 4.75

9.5, 11.75

<u>Step-by-step explanation:</u>

It is given that the PERIMETER is BETWEEN 24 and 33

--> 24 < P < 33

Graph: O------------------O

24 33

Perimeter = 2w + 2L

It is given that L = w + 7

Substitute P with 2w + 2L and substitute L with w + 7

24 < 2w + 2(w + 7) < 33

24 < 2w + 2w + 14 < 33

10 < 4w < 19

--> 2.5 < w < 4.75

Graph: O--------------------------O

2.5 4.75

Since L = w + 7, then w = L - 7

Substitute P with 2w + 2L and substitute w with L - 7

24 < 2(L - 7) + 2L < 33

24 < 2L + 2L - 14 < 33

38 < 4L < 47

--> 9.5 < L < 11.75

Graph: O------------------------O

9.5 11.75

In a certain? country, the true probability of a baby being a boy is 0.534. among the next six randomly selected births in the?

OLEGan [10]

Finding the "probability that at least one is girl" can be done much easier by subtracting the "probability that none is girl" from 1, since these 2 events are the complement of each other, and either one or the other, but never both, may happen.

consider the tree diagram of the problem, check the picture, each branching represents a birth. The only branch where there is no girl (no g), is

bbbbbb with a probability of (1-0.534=0.466) per each letter b.

we know that the probability of a particular branch is the multiplication of the probabilities of each letter in the branch.

so in the case, P(bbbbbb)= $(0.466)^{6}= 0.01$

finally, P(at least 1 girl) = 1- P(no girl)=1-P(bbbbbb)=1-0.01=0.99

Answer: 0.99

$\bf \stackrel{\textit{time \underline{t} required to drive a certain distance varies inversely with the speed \underline{r}}}{t=\cfrac{k}{r}}
\\\\\\
\textit{we also know that }
\begin{cases}

140=k\qquad therefore\qquad \boxed{t=\cfrac{140}{r}}

\textit{now, when \underline{r} = 45, what is \underline{t}?}\qquad t=\cfrac{140}{45}$
