If y varies directly as x, and y is 18 when x is 5, which expression can be used to find the value of y when x is 11?

Oy- (11

y (11)

(18)(5)

oy-

5

11

2 y = (1865

**Answer:**

**y = 18/5(11)**

**Step-by-step explanation:**

If y varies directly as x, this is expressed as;

y∝x

y = kx

k is the constant of proportional constant

if y = 18 and x = 5

18 = 5k

k = 18/5

to get the expression that can be used to find the value of y when x is 11

y = kx

**y = 18/5(11)**

**This gives the required expression**

Write all the factors of S 35. Use commas to senarate them 。

**Answer:**

All of the positive integers that can divide evenly into 35 (they are the factors) are:

1, 5, 7, 35

All others, like 2, 3, 13, ... create a remainder that is not 0.

Now, you may (or soon will be) learning about the prime factors of 35 (not 1, and only divisible by itself and 1). They are:

5, 7

In one company, 20% of the workers in the technical department applied for vacation at the same time. If 12 workers applied for vacation, how many tech workers are there, altogether?

**Answer:**

There are 60 tech workers altogether

**Step-by-step explanation:**

Let X be the total number of tech workers in the company

Out of X tech employees, 20 % applied for leaves

In totality, 12 tech employees are on leave

Thus,

[tex]\frac{20}{100} * X = 12[/tex]

On solving the above mathematical equation, we get -

[tex]X = \frac{12*100}{20} \\X = 60[/tex]

Hence, there are 60 tech workers altogether

Jacob did the following calculations, please explain the error if any. (2-3i)2 = (2-3i)(2-3i) = 4-6i-6i+9i2 = 9i2-12i+4

There is no error, Jacob expand the equation correctly but can go a step further knowing that i^2=-1 so they would have 4-12i+9(-1)=4-12i-9=-5-12i

Ajar contains $36.25 in dimes (10 cents) and quarters (25 cents). There are 250

coins in the jar. How many quarters are there in the jar?

**Answer:**

**Step-by-step explanation: **

**The jar contains 2 types of coins dimes and quarters**

**the total amount is equal to 36.25 dollars**

**the total number of coins is 250**

**let number of dimes be x and quarters be y**

**let us put the equation**

**0.10x + 0.25y = 36.25**

**for our convinience convert all money to cents i.e. = 3625 cents **

**now the equations are **

**10x + 25y = 3625**

**x + y = 250 **

**we need to solve for y i.e. number of quaters **

**y = 250 - x**

**rewrite the equation substituting y in x place **

**10(250 - y) +25 y = 3625**

**2500 - 10y +25y = 3625**

**15y = 1125**

**y = 75**

**so the number of quarters = 75**

**cross checking :**

**number of dimes = 250 - 75 = 175**

**total = 10x175 + 25x75 = 1750 + 1875 = 3625 = $36.25**

The winner of a basketball contest is the individual who scores the highest percentage of free throws. The too three finishers are contestants A, B, and C. Contestant A made 85% of her free throws, contestant B made 0.88 of his free throws, and contestant C made 21/25 of his free throws. Graph in inequality that represents the possible percentages (in decimal form) of free throws made by the other contestants in the competition. (Assume there are no ties.)

**Answer:**

**Step-by-step explanation:**

Less than 0.84

Step-by-step explanation:

Convert all numbers to decimals

85% --> 0.85

0.88 --> 0.88

21/25 --> 0.84

Since these are the top three, the rest of the competitors are less than 0.84.

**Answer:**

**Step-by-step explanation:**

Middle School:

Find the median by arranging the data points from smallest to largest.

1, 1, 1, 3, 4, 4, 5, 6 (Take the average of the two points in the middle, 3 and 4)

7/2 = 3.5

High School:

1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 4 (Take the average of the two points in the middle, 2 and 2)

4/2 = 2

Most of the points in the middle school plot are four or less.

A (High school students had more variation.)

a)

Estimate the probability that on the next roll the score will be 4.

b)

If the dice is rolled 400 times, about how many 2s would you expect to get?

Answer:

a) 1/10

b) 110

Step-by-step explanation:

A) we start by getting the total number of rolls

That would be;

11 + 22 + 7 + 8 + 13 + 19 = 80

The frequency of getting a 4 is 8

The probability that the next roll will be a 4 is;

8/80 = 1/10

b) Firstly, we get the probability of getting a 2

We have this as:

22/80

So for 400 rolls, the number of 2’s will be;

22/80 * 400

= 22 * 5 = 110

The circumference of a steering wheel is 19.8in. What is the radius

A. 3.2

B. 1.3

Please!!!! Help!!!! this a important test

I will mark you brainliest

If i get the correct answer Please!!!!

**Answer:**

A. 3.2

**Step-by-step explanation:**

Given

Circumference (c) = 19.8 in

Radius (r) = ?

We know

2πr = c

2 * 3.14 * r = 19.8

6.28 r = 19.8

r = 19.8 / 6.28

r = 3.2 in

The ratio of marbles to stones in a large pot is 6 to 7. If there are 42 marbles, then how many stones are there?

**Answer:**

49 stones

**Step-by-step explanation:**

Write the following proportion based on the given ratio of marbles (m) to stones (s), and naming the unknown number of stones to find, with the letter "X":

6 m / 7 s = 42 m / X s

cross multiply to get the unknown in the numerator:

6 * X = 42 * 7

divide both sides by 6 to isolate X entirely on the left of the equal sign

X = ( 42 * 7 ) / 6

X = 49

Therefore, there are **49 stones**

The spinner shown is divided into equal sections that each contain one number, so that the probability of spinning each number on the spinner is the same. However, there are two red sections, and therefore there are a total of two numbers (1 and 3) that appear in red sections, while each other color appears in only one section.

A spinner with 6 equal-sized sections labeled 1 through 6. Sections 1 and 3 are red. Section 2 is blue. Section 4 is orange. Section 5 is purple. Section 6 is green.

If ∆ABC ∼ ∆PQR such that AB = 1.8cm and PQ = 1.6 cm, what is the ratio of the areas of ∆ABC and ∆PQR.

Answer:

81 / 64

Step-by-step explanation:

The ratio of the areas can be obtained thus :

Area of ∆ABC / Area of ∆PQR

Area of ∆ABC / Area of ∆PQR = AB² / PQ²

AB = 1.8 ; PQ = 1.6

AB² / PQ² = 1.8² / 1.6²

= 18² / 16²

= 324 / 256

= 81 / 64
