Answer:

For every 5 blonde teachers there are 3 brown teachers.

Step-by-step explanation:

Here we have to find the ratio of blonde teachers to brown teachers

Blonde : Brown

20: 12

10:6

5:3

For every 5 blonde teachers there are 3 brown teachers.

This can be further evaluated

Blonde : Brown

5:3

dividing both sides by 5

1: 3/5

For every 1 blonde teachers there are 3/5 brown teachers. It means that the brown teachers are 2/5 less than the blonde teachers.

1-2/5= 3/5

20* 3/5= 12

Answer:

$8.50

Step-by-step explanation:

[tex]\frac{y}{22.10} =\frac{1}{2.6}[/tex]

2.6 × y = 22.1 × 1

2.6y = 22.1

2.6y ÷ 2.6 = 22.1 ÷ 2.6

y = 8.5

Answer:

About 3000 feet

Step-by-step explanation:

This is a 30,60 90 triangle, all the angles in a triangle adds up to 180.

Use sin ratio

sin 60 = [tex]\frac{o}{4000}[/tex]  o for opposite side of triangle from the 60 degree angle

o = 4000 (sin 60) = 3464.11

Use cosine

cos 30 = [tex]\frac{a}{3464.11}[/tex]   a for adjacent side of triangle from the 30 degree angle

3464.11 (cos 30) = 3000.01

Answer:

64

Step-by-step explanation:

In this problem n is 6 which represents the sixth and final hour of the period. Therefore gn = g6.

g1 = 2 which is the first value in the sequence which corresponds to the first hour where 2 people know the                 rumor.

r = the common ratio is 2, because each successive hour the people who know the rumor doubles... {2, 4, 8...}.

Substitute into equation:     g6 = 2 x 26-1 = 2 x 25 = 2  x 32 = 64 Answer is 64.

Answer:

1/36

Step-by-step explanation:

Probability is the likelihood of chance that an event will occur. Mathematically,

Probability = expected outcome/total outcome

If a bag contains two white blocks, one red block and 3 purple block

Total outcome = 2+1+3= 6

Probability that white ball is selected = 2/6

Probability that red ball is selected = 1/6

Probability that white ball is selected = 3/6

Probability of picking a ball is 2/6 × 1/6 × 3/6

Probability of picking a ball = 6/216

Probability of picking a ball = 1/36

Answer:

This is very similar to what we are proving if you just change the angles.

Answer:

2.7 kb

Step-by-step explanation:

Total kb = 7.48

Total apps = 2

one app = 4.78

another app = x

> 4.78 + x = 7.48

x = 7.48 – 4.78

= 2.7 kb

total cost =rate× area =$21×7/3=$49

Answer:

The answer is 225

Step-by-step explanation:

Because you first need to subtract 350-125 and you get 225

Answer:

the slope, m, is 4 and that the y-intercept, b, is -8

Step-by-step explanation:

Compare the given equation to the slope-intercept form y = mx + b.  Here we see that the slope, m, is 4 and that the y-intercept, b, is -8.

Answer:

Mean would be most affected

Step-by-step explanation:

The mean is defined as the average value . If the data has extreme values then the average value automatically changes.

The median is the value which divides the data in to two halves. It is not affected by the extreme values. The middle value remains the same.

The mode is the value which occurs repeatedly. An extreme value in a data does not affect the mode.

For example I have 5 chocolate bars of sizes 5,6,7,7,9  and another 5 chocolate bars of sizes  5,6,7,7,12

Mean for the two sizes will be 34/5= 6.8  and 37/5=7.4

The median and mode in both sets is 7

So the mean is most affected with change in value.

11. y=(3/2)x-2

12. y=x+3

13. y=(3/5)x-4

14. y=3x-1

15. y=(5/4)x

im not 100% sure on 14 but the rest of them should b right :)

Answer:

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The multiplication of 4/7 x 5/6 as a fraction in the simplest form​ is 10/21.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

The multiplication of the two fractions 4/7 and 5/6 can be done as,

4/7 × 5/6

Multiply the numerator and the denominator of the two fractions

= (4×5)/(7×6)

= 20/42

Dividing both the numerator and the denominator by 2 to simplify,

= 10/21

Hence, the multiplication of 4/7 x 5/6 as a fraction in the simplest form​ is 10/21.

Answer:

10 cent coins = 43

Step-by-step explanation:

x = 10 cent coins

y = 5 cent coins

x + y = 157, then y = 157 - x

$10 = 1000 cents

0.10x + 0.05y =1000

substitute for y:

0.10x + 0.05(157 - x) = 1000

0.10x + 7.85 - 0.05x = 1000

combine like terms:

0.05x = 2.15

x = 43

y = 114

AB = CD

So option C is right

Option (3) is correct. The slope of CD = 1/2.

"A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees, opposite sides are parallel and adjacent sides are perpendicular.

For the given situation,

Consider the rectangle ABCD,

The slope of [tex]AB=\frac{1}{2}[/tex]

The slope of parallel sides are equal. Here AB and CD are parallel sides.

So, slope of [tex]AB=CD[/tex].

Hence we can conclude that the slope of CD = 1/2. So, option (3) is correct.
