Answer:

C) 161/163

Step-by-step explanation:

First, you add up all the students for both genders.

Female- 193+ 214 +197+ 201 = 805

Male- 216+ 207+ 198 + 194 = 815

That gives you a fraction on 805/815 which you simplify to 161/163

So your answer would be C, 161/163 :)

andreyandreev [35.5K]

Answer: Her measuring cup has 8.25 mL of medicine.

Step-by-step explanation:

As per given,

In 11 mL of medicine, there are 20 drops.

That means quantity in 1 drop = $\dfrac{11}{20}$ mL

Now , the quantity in 15 drops = 15 x quantity in 1 drop

= $15\times\dfrac{11}{20}$

$=\dfrac{33}{4}$

= 8.25 mL

Hence, her measuring cup has 8.25 mL of medicine.

A writing workshop enrolls novelist and poets in a ratio of 5:3. There are 24 people at the workshop. How many novelist are ther

Harman [31]

Answer:

There are 15 novelist and 9 poets at the writing workshop.

Step-by-step explanation:

Given,

Total number of people at the workshop = 24

We have to find the number of novelist and poets at the workshop.

Solution,

Since the ratio of novelist and poets is 5:3.

Then we can say that the number of novelist is '5x' and the number of poets is '3x'.

Now according to question, total number of people is the sum of number of novelist and number of poets.

So, framing the above sentence in equation form, we get;

Total number of people = number of novelist + number of poets

On substituting the given values, we get;

$5x+3x=24\\\\8x=24$

On using division property we will divide by '8' on both side and get;

$\frac{8x}{8}=\frac{24}{8}\\\\x=3$

Now we substitute the value of 'x' to get the number of novelist as well as poets.

Number of novelist = $5x=5\times3=15$

Number of poets = $3x=3\times3=9$

Hence There are 15 novelist and 9 poets at the writing workshop.

(4) A taxi service charges Rs.100 as an initial fee and Rs.50 for each kilometer travelled. Write an algebraic expression for th

vredina [299]

Answer:

f(x) = 50x + 100

Explanation:

The term "Rs. 100" is constant. The term "Rs. 50" keeps changing per km.

Linear equation: y = mx + b, where 'm' is rate of change, 'b' is constant

Equation built:

f(x) = 50x + 100

This will determine the cost for journey of x meters.

The weight of water is 62 1/2 per cubic feet. Water that weighs 325 lbs will fill how many cubic feet

yulyashka [42]

Water that weighs 325 lbs will fill 5.2 cubic feet.

Step-by-step explanation:

This is a simple question of cross multiplication

DATA:

1. The weight of water for 1 cubic feet is 62.5

2. The weight of water for 'X' cubic feet is 325

3. To find x, form an equation:

Cubic feet : Weight of water

1 : 62.5

X : 325

4. Cross multiply

X x 62.5 = 1 x 325

62.5X = 325

5. Make X the subject

X = $\frac{325}{62.5}$

6. Solve to find X

X = 5.2 cubic feet

Therefore, water that weighs 325 lbs will fill 5.2 cubic feet.

The first side of a triangle is 4 inches longer then twice th second side the third side of a trianhle

Law Incorporation [45]

Question:

The first side of a triangle is four inches longer than twice the

second side. The third side of the triangle is 5 inches shorter than

the sum of the other two sides. The perimeter is 72 inches. Find

the lengths of the three sides.

Answer:

The sides of the triangle are: 11.5, 27 and 33.5

Step-by-step explanation:

Let the first side be f, the second be s and the third be t.

So, we have:

$f =4 + 2s$

$t = f + s - 5$

$Perimeter = 72$

Required

Determine the length of the three sides

Perimeter is calculated as:

$Perimeter = f + t + s$

Substitute values for f and t

$Perimeter = 4+2s + f+s-5 + s$

$Perimeter = f+2s +s+s-5+4$

$Perimeter = f+4s-1$

Substitute values for f and Perimeter

$72 = 4+2s+4s-1$

$72 = 2s+4s-1+4$

$72 = 6s+3$

Collect Like Terms

$6s = 72 -3$

$6s = 69$

$s= 11.5$

$f =4 + 2s$

$f = 4 + 2 *11.5$

$f = 27$

$t = f + s - 5$

$t=27+11.5 - 5$

$t=33.5$

The sides of the triangle are: 11.5, 27 and 33.5
