find the value of x for mAB=34 and mCD=25 (The figure is not drawn to scale.)

Multiple choice :
59
9
29.5
46.5

Answer:

8 students

Step-by-step explanation:

Number of people who voted for dogs:

12

Number of people who voted for fish:

4

We find the difference between the 2:

12 - 4 = 8

Answer:

8 students voted for dogs than fish.

Step-by-step explanation:

so if we look at the graph 12 students voted for dogs and 4 students voted for fish. so now we have to subtract both of these numbers to find how many more students voted for dogs than fish.

12 - 4 = 8

Have a nice day!

This is my 200th answer!!!

Answer:

one board game cost 15 dollars

75/5=15

15y

y = number of board games and 15= the price of each board game

so to calculate any number of board games bought just input the number of board games bought for y in the expression 15y and you will get the price.

Step-by-step explanation:

Given:

Sum of ages of brother and sister = 15

Product of their ages = 54

To find:

How old is the older one between the two of them?

Solution:

Let x be the age of brother and y be the age of sister.

Sum of ages of brother and sister = 15

[tex]x+y=15[/tex]

[tex]x=15-y[/tex]                ...(i)

Product of their ages = 54

[tex]xy=54[/tex]

[tex](15-y)y=54[/tex]                [Using (i)]

[tex]15y-y^2=54[/tex]

[tex]0=54-15y+y^2[/tex]

Splitting the middle term, we get

[tex]54-15y+y^2=0[/tex]

[tex]54-9y-6y+y^2=0[/tex]

[tex]9(6-y)-y(6-y)=0[/tex]

[tex](6-y)(9-y)=0[/tex]

Using zero product property, we get

[tex](6-y)=0\text{ and }(9-y)=0[/tex]

[tex]y=6\text{ and }y=9[/tex]

If [tex]y=6[/tex], then using (i), we get

[tex]x=15-6[/tex]

[tex]x=9[/tex]

If [tex]y=9[/tex], then using (i), we get

[tex]x=15-9[/tex]

[tex]x=6[/tex]

Therefore, the age of older one is 9, the age of younger one is 6 and the difference between their ages is 3.

Answer:

6

Step-by-step explanation:

9 - 3 = 6

Answer: Reflection about x-axis

Step-by-step explanation:

Given

Initially, vertices are [tex]A(-2,0), B(2,5),C(3,1)[/tex]

After reflection they become [tex]A(-2,0),B(2,-5),C(3,-1)[/tex]

It is clear that the x coordinate remains unchanged and the y coordinate changes its sign. It occurs when reflection is done about the x-axis.

For example, when (a,b) is reflected about the x-axis, it becomes (a,-b).

So, here reflection is being done about the x-axis.

Answer: B, E

Step-by-step explanation:

Answer:

answer: 50%

Step-by-step explanation:

The answer is 50% because 15 is half of 30 because 15 + 15 = 30 so 15 is half of 30 50%

Answer:

725.7 m²

Step-by-step explanation:

A=2πrh

r=16 1/2 ÷ 2 = 8 1/4

Answer:

Step-by-step explanation:

Answer:

14

Step-by-step explanation:

Sum of the first five numbers = 40

The sum of the six numbers should equal 9 x 6 = 54

So, you would do 54 - 40 = 14

Answer:

The Mean 14.5 and the Median is 15

Step-by-step explanation:

For the Mean you just add all the numbers up and divide on how many you have. And the Median the middle

Answer:

Below in bold.

Step-by-step explanation:

First arrange in ascending order:

5 8 9 11 13 15 16 17 17 18 22 23

Median = mean of the middle 2 values = (15+16)/2 = 15.5.

Mean = Sum of all the values / 12 = 174/12 = 14.5.

Interquartile range =  upper quartile - lower quartile = 17 - 11 = 6.

3 because 2 of them played during spring and winter. 6 of them played during spring and fall. and 13 played during fall and winter. but your asking for year round which is all three seasons meaning only 3 played year round.

Answer:they have eaten 3/4 of the total pizza

Step-by-step explanation:

Let the whole pizza =1whole

Amount eaten by Toby =1/2

Amount eaten by Ahmed =1/4

Total Amount eaten by both of them =1/2 +1/4 =  2+1/ 4=3/4

Therefore, they have eaten 3/4 of the total pizza

Answer: You are correct. The mode is between 90 and 100

This is because the tallest bar corresponds to this interval. The mode is the most frequent value.

i am not sure but i hope this can help you

Answer:

Median = 10

Mean = 18

Step-by-step explanation:

1) Median equals the middle number of a set.

To find median, place the numbers from least to greatest. So that’ll turn to be:

0, 8, 9, 10, 26, 35, 38

The middle number is 10.

2) Mean is the average of all the numbers.

To find mean, add all the numbers together. So 0+8+9+10+26+35+38 = 126

Then, divide the sum by the amount of numbers you added. We added a total of 7 numbers to get 126. 126/7 = 18. The average is 18.

Answer:

The median is 10 and the mean is 18 . Hope it help

Step-by-step explanation:

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest

Answer:

The value of 1 tenth is less than the value of 1 ten.

Step-by-step explanation:

Answer:

Because 3 x 1/10 = 3/10

whereas 3 x 10 = 30

and 3/10 < 30

Also b/c 1/10 < 10 and they are multiplied by the same value (3)

Answer:

70 km/h

Step-by-step explanation:

Answer:

70

Step-by-step explanation:

Let the no of books bought be x

The cost price of 1 book is 5x

No of the missing book is 15

The remaining book is x-15

The selling price of 1 book is 87

Selling price of (x-15) book is 87

Hence the number of books can be calculated as follows

8(x-15)-5x= 90

8x-120-5x= 90

8x-5x= 90+120

3x= 210

x= 210/3

= 70

Hence the number of books bought is 70
