He should have written it as 24:10.Jeff did not write the ratio in the correct order. He should have written it as 12:5.

Answers

Answer:

The correct option A.

Step-by-step explanation:

Total numbers of students = 24.

Number of boys = 10

Number of girls = 24 - 10 = 14

Jeff claims that the ratio of boys to girls in this class must be 5:12.

The ratio of the number of boys to the total number of students is

$(boys)/(students)=(10)/(24)=(5)/(12)=5:12$

Therefore Jeff found the ratio of the number of boys to the total number of students.

The ratio of boys to girls in this class is

$(boys)/(girls)=(10)/(14)=(5)/(7)=5:7$

Therefore the ratio of boys to girls in this class is 5:7.

Option A is correct.

The ratio is 10:14 or 5:7 which is the ratio of boys to girls!

What is 1/2 + (-3/4)

?????????????????

Answers

1/2 + (-3/4)

= 1/2 - 3/4

= 2/4 - 3/4

= -1/4

$(1)/(2) + (-(3)/(4)) = \n \n (1^((2))/(2)- (3)/(4) = \n \n (2)/(4)- (3)/(4) = \underline{\boxed{(-1)/(4)} }$

Can someone explain major and minor arcs in relation to circles.

Answers

A Major Arc within a circle is something that that is more than half of the circle, and therefore, larger than the minor arc. The way in which this could be used in an example is; Tony has a pizza with 8 slices, 6 of these slices are pepperoni and 2 are chilli beef. In this case, the pepperoni slices are the major arc and the chilli beef slices are the minor arc.
The Major Arc will always be bigger than the minor arc- whether this is 181 degrees to 179, or whether this is 350 degrees to 10 degrees.
The Minor Arc is always the smallest arc, and this can be explained by; Benedict has an apple pie that has 10 slices, between him and his friends, they have eaten four slices. In this case, they have eaten the 'minor arc'
There is a picture attached, and this is the examples of a major and a minor arc.
Hope this has been able to help you :)

Brownies are now on sale. Each brownie costs $0.20 less than the original price. Right now, if you buy 8 of them it will cost $15.20

Answers

Answer: The original price of brownie was $2.1 each.

Step-by-step explanation:

since we have given that

Let the original price will be x

Number of brownie purchased = 8

According to question , each brownie costs $0.20 less than the original price.

So, it becomes

$8* (x-0.20)=\$15.20\n\n8x-1.6=15.20\n\n8x=15.20+1.60\n\n8x=16.8\n\nx=(16.8)/(8)\n\nx=\$2.1$

Hence, the original price of brownie was $2.1 each.

Write the equation of a line through the points (2,3) and (-1,-9)

Answers

Answer:

with the points (2,3) and (-1,-9) the answer is y=4x+10

Step-by-step explanation:

you have to do (x1,y1) (x2,y2) thats for each point

the equation to get the slope is y2-y1 divided by x2,x1

to get the y-intercept to plug in one of the points to the slope-intercept equation

y=4x+5

I picked the points (2,3) but you should get the same answer with the other points

3=4(2)=5

3=8+5

3=13

-3+-3

=10 thats your y intercept.
