Stella is making 25 sundaes with mint, chocolate, and vanilla ice cream. 1 5 of the sundaes are mint ice cream and 1 2 of the re

o-na [289]

Answer:

Vanilla = 10 sundaes

Step-by-step explanation:

Total sundaes = 25

1/5 of the sundaes are mint ice cream

Mint ice cream = 1/5 of 25

= 1/5 * 25

= 25/5

= 5

Sundaes remaining = total sundaes - sundaes for mint ice cream

= 25 - 5

= 20 sundaes

Sundaes remaining = 20 sundaes

1/2 of the remaining sundaes are chocolate

= 1/2 of 20

= 1/2 * 20

= 20/2

= 10

Chocolate ice cream = 10

The rest will be vanilla

Sundaes remaining = 20 - 10

= 10 sundaes

Vanilla = 10 sundaes

F and H are sets of real numbers defined as follows.

Marina CMI [18]

Answer:

$(a)F \cup H=(3, \infty)\\(b)F \cap H=(6, \infty)$

Step-by-step explanation:

Given the sets F and H of real numbers defined as given:

F={w | w>3}

H={w | w>6}

To write a set in interval notation, we use these brackets, ( ) for < or > while we use [ or ] for $\leq $ or \geq$ .

Since our sets are defined by strict inequalities(< or >)

In interval notation

$F=(3,\infty), H=(6,\infty)$

$(a) F \cup H =(3,\infty) \cup (6,\infty) \\\\F \cup H=(3, \infty)\\\\(b) F \cap H =(3,\infty) \cap (6,\infty) \\\\F \cap H=(6, \infty)$

I don't understand how to answer this

IgorLugansk [536]

Answer:

$\large\boxe{D)\ \dfrac{1}{2}\pi\ feet}$

Step-by-step explanation:

Step 1:

Calculate the circumference of both circles.

The formula of a circumference:of a circle with radius r:

$C=2\pi r$

The circle R:

$C_R=2\pi\left(\dfrac{2}{3}\right)=\dfrac{4\pi}{3}\ ft$

The circle S:

$C_S=2\pi\left(\dfrac{3}{4}\right)=\dfrac{3\pi}{2}\ ft$

The length of the intercepted arc for circle R is

$l=\dfrac{4\pi}{9}\ ft$

Step 2:

Calculate what the part of the circumference of the circle R is the intercepted arc:

$\dfrac{4\pi}{9}:\dfrac{4\pi}{3}=\dfrac{4\pi}{9}\cdot\dfrac{3}{4\pi}=\dfrac{1}{3}$

The same length of the circumference of the circle S is searched for the length of the intercepted arc for circle S.

Step 3:

Calculate the length of the intercepted arc for circle S:

$\dfrac{1}{3}\cdot\dfrac{3\pi}{2}=\dfrac{1}{2}\pi\ ft$

I need help on this question about percentages

Vera_Pavlovna [14]

Sales above monthly quota = 23800 - 17000 = $6800

So her commission = 0.05 * 6,800 = $340

Therefore her total salary for the month = 3600 + 340

= $3,940 (answer).
