Answer:

f=16/7.3x

Step-by-step explanation:

Lets solve for f:

f(7.3)=16

Step 1:Divide both sides by 7.3x

7.3f/7.3x=16/17.3x

f=16/7.3x

You can spend at most $21 on fruit. Blueberries cost $4 per pound, and strawberries cost $3 per pound. You need at least 3 pound

Juliette [100K]

Answer:

<h2>a. The system of linear inequalities is $x + y \geq 3$ and $4x + 3y \leq 21$ .</h2><h2>b. The solution is given in the figure.</h2><h2>c. The given scenario can happen.</h2>

Step-by-step explanation:

Let, I will buy x pounds Blueberries and y pounds Strawberries.

I need to collect at least 3 pounds of fruits.

Hence, $x + y \geq 3$ .

It also given that I can not spend more than $21, that is $4x + 3y \leq 21$ .

If I will buy 4 pound Blueberries and 1 pound Strawberry, then x = 4 and y = 1.

Now, 4 + 1 = 5 > 3. First inequality is satisfied.

$4x + 3y = 4\times4 + 3\times1 = 16 + 3 = 19 \leq 21$ , Second inequality is also satisfied.

Triangles R S T and V U T are connected at point T. Angles R S T and V U T are right angles. The length of side R S is 12 and th

kkurt [141]

Answer:

$\dfrac{\overline{RS}}{\overline{VU}}=\dfrac{\overline{ST}}{\overline{UT}}\quad\text{and}\quad\angle S\cong\angle U$

Step-by-step explanation:

To use the SAS similarity theorem, you must show proportionality between corresponding sides, and congruence of the angle between them.

The answer shown above is the only answer choice that mentions an angle.

<em>Comment on other choices</em>

Choice B shows the three sides are proportional, so would be useful if the SSS similarity theorem were to be invoked. It isn't helpful for the using the SAS similarity theorem.

Choices C and D get the proportion statements wrong.
