Priya has a recipe for banana bread. She uses 7/1/2 cups of flour to make 3 loaves of banana bread. Andre will follow the same r

wlad13 [49]

Answer:

5b=2f

Step-by-step explanation:

Priya uses $7\dfrac{1}{2}$ cups of floor to make 3 loaves of banana bread.

Andre will follow the same recipe. He will make b loaves of banana bread using f cups of flour.

To find the relation between b and f, the steps are as follows :

$\dfrac{\text{cups of flour}}{\text{loaves of banana bread}}=\dfrac{7 \dfrac{1}{2}}{3}\\\\=\dfrac{\dfrac{15}{2}}{3}\\\\=\dfrac{15}{2}\times \dfrac{1}{3}\\\\=\dfrac{5}{2}$

It means,

$\dfrac{f}{b}=\dfrac{5}{2}\\\\5b=2f$

So, the relationship between b and f is "5b=2f".

If B=16°45’ and c=13 then find a (picture provided)

SIZIF [17.4K]

Answer:

A. 12.4

Step-by-step explanation:

To find a, we'll use the Law of Sines that says:

$\frac{a}{sin(A)} = \frac{c}{sin(C)}$

And we'll isolate a to get:

$a = \frac{sin(A) * c}{sin(C)}$

We first need to find A, which is easy. The sum of the interior angles of a triangle is 180 degrees... and we already have 2 of them, so:

A = 180 - 90 - 16.75 = 73.25

(converted 16°45' to 16.75)

Then we will plug-in the information we already have

$c = \frac{sin(73.25) * 13}{sin(90)} = 12.45$

So, let's round it to 12.4 to match the answer A.

Which of the ordered pairs below could NOT be in this function? {(1, 2), (2, 3), (3, 4), (4, 5)}

Oxana [17]

In order for something to be a function, it cannot have an x-value repeated. Therefore, (1,0) cannot be a possible ordered pair because the function already has a point at x=1 (1,2).
