Answer:
d+6
Step-by-step explanation:
Because d is representing dogs and sum means add, and it's asking to add the number of cats which is 6 so it's d+6
Angles M and N are complementary angles. If angle M is 3x+15 and angle N is 2x+35, what is the measure of angle N?
Use your value of x to find the measure of angle N.
Please help I’m stuck!
Answer:
Step-by-step explanation:
2x+35+3x+15=90(being perpendicular)
5x+50=90
5x=90-50
x=30/5
x=6
Angle N=2x+35
=2*6+35
=12+35

Musical High School has a band that contains four members: (A)vi, (B)rianna, (C)alvin, and (D)achen. Students in the high school must vote for who they like in the band, and they can vote for none of them or for one or more members of the band. There are 3000 students in the school (including the band members), but the band members cannot vote. 1000 students vote for member A. 1000 students vote for member B. 1000 students vote for member C and 1000 vote for member D. 250 students vote for both A and B. 250 students vote for both A and B. 250 students vote for both A and C, 250 students vote for both A and D. 250 students vote for both B and C. 250 students vote for both B and D. 250 students vote for both C and D. 100 students vote for A,B, and C. 100 students vote for A,B, and D. 100 students vote for A,C, and D. 100 students vote for B,C and D. 50 students vote for all of them. What is the number of students that voted for no one?
Answer:
146 didn't vote
Step-by-step explanation:
With this situation, start from the vote for all 4, then move onto the vote of 3 out of 4, then the vote of 2 of the 4 and lastly deal with with the vote of 1 out of the 4;
I've tabulated it in the attached excel document;
First, there are 50 votes for A, B, C and D;
Then there are 100 votes for B, C and D;
Now, the 50 who voted for all 4 are included in the 100 for B, C and D because someone who votes for A, B, C and D has voted for B, C and D;
This means we need to deduct 50 from 100 to get 50, which is the number of voters who voted for B, C and D, but not A;
This is done for all the options where students voted for 3 of the 4;
For those who voted C and D, there are 250, but this will include the 50 who voted A, C and D, the 50 who voted B, C and D and the 50 who voted A, B, C and D;
So, we have to subtract 3×50 (= 150) from 250 to get 100 as is shown in the table;
The table is quite helpful as it shows clearly who will be included in the numbers given in the question info;
We do the same for all those who vote for 2 of the 4;
For those who voted just D, we need to add the votes of all those who voted for D and anyone else, which is 500, and subtract this from the total number of votes for D, which is 1000;
And similarly, we do the same for A, B and C as well;
Now, we can sum all the votes, which gives 2850 and subtract this from the total number of voters, which is 2996 (remember we have to exclude the 4 band members as they can't vote);
This gives us:
2996 - 2850 = 146

9514 1404 393
Answer:
3
Step-by-step explanation:
The common difference of an arithmetic sequence is the slope of the equation that describes it. The slope formula is useful in this case:
m = (y2 -y1)/(x2 -x1)
m = (219 -213)/(4 -2) = 6/2 = 3
The common difference of the corresponding arithmetic sequence is 3.

A honeydew melon is shaped like a sphere with a diameter of 8 inches. Which value is closest to the volume of the melon?
Answer:
The volume of sphere = 268.08
Step-by-step explanation:
Below is the calculation for the volume of melon (sphere).
Given the diameter of the sphere is = 8 inches
Now find the radius by dividing the diameter by 2 = 8/2 = 4 inches
Now use the below formula to find the volume.
The volume of sphere = [tex]\frac{4}{3} \times \pi \times r^{3}[/tex]
The volume of sphere = 268.08

1) Find the distance between -49.75 and 31.5 on a number line.
Answer:
81.25
Step-by-step explanation:
Because you want to know the total distance, calculate how many digits -49.75 is away from 0. It is 49.75 digits away from 0.
Now calculate how many digits 31.5 is away from 0. It is 31.5 digits away from 0.
Finally, add those two distances together so that you know the total distance:
49.75+31.5 = 81.25

1. Consider the sequence: 3, 7, 11, 15...
Find an explicit formula for the n-th term of this sequence.
Answer:
Step-by-step explanation:
This is arithmetic since adding 4 to each term gets us to the next term in the sequence. That means that the common difference, d, is 4. The general arithmetic explicit formula is
[tex]a_n=a_1+d(n-1)[/tex] and using the info given when a1 = 3 and d = 4:
[tex]a_n=3+4(n-1)[/tex] or, if you want to make it easier to deal with:
[tex]a_n=4n-1[/tex] (I just distributed through the parenthesis and then combined like terms. As you can see, arithmetic sequences are linear).

Step-by-step explanation:
The sum of two numbers is 90. The larger
number is 14 more than 3 times the smaller
number. Find the numbers.
First complete the equations below, where x stands for
the larger number and y stands for the smaller number.
x + y = [?]; x = + ly
Step-by-step explanation:
Let the larger number be x and smaller number be y.
→ Sum of two numbers = 90
→ x + y = 90_(1)
Also,
→ Larger number = 14 + 3(Smaller number)
→ x = 14 + 3y_(2)
Substitute the value of x from equation (2) to (1) :
→ x + y = 90
→ 14 + 3y + y = 90
→ 14 + 4y = 90
→ 4y = 90 - 14
→ 4y = 76
→ y = 76 ÷ 4
→ y = 19
And, from the equation (2) ;
→ x = 14 + 3y
→ x = 14 + 3(19)
→ x = 14 + 57
→ x = 71
Therefore, larger number is 71 and smaller number is 19.

Answer and Step-by-step explanation:
In a polygon, when a shape is similar but dilated, the angles are still congruent.
Also, turn the pentagon QRSTP counterclockwise 90 degrees so it is upright and looks like pentagon ABCDE (making it easier to read).
A. The measure of angle P is 124 degrees, as it matches up with angle E.
B. To find the length of side r, we need to find the scale factor. We do this by looking at the given side on pentagon QRSTP (side RS) and match it with its similar side of pentagon ABCDE (side BC)
To find the scale factor, you divide the side of the bigger shape by the side of the smaller shape. For us, this results in the scale factor being 2.
Now, the similar side to r is side ED. We need to divide 7.5 by 2 to find r.
When doing so, we get r to be 3.75.

Step-by-step explanation:
What is the slope in this equation? Y=3x
Answer:
3
Step-by-step explanation:
y = mx + b
m = slope
In this equation,
m = 3
Thus, the slope, or m, is 3.
General equation for slope-intercept form
y=mx+C
where m is slope
Comparing the given eqn y=3x
m= 3
Therefore, slope = 3
Write the error interval for x , where x=4.7 , truncated to 1 decimal place.
Error interval for x is 4.65 ≤ x < 4.75.
What is error interval?Error intervals are the limits of accuracy when a number has been rounded or truncated. They are the range of possible values that a number could have been before it was rounded or truncated.
The error is rounding the number is half of the unit of measure.
The number was rounded to the nearest 0.1 unit. so the error is half of 0.1 which is [tex]\frac{1}{2}[/tex] × [tex]0.1[/tex] = 0.05
∵ 4.7 + 0.05 = 4.75
and 4.7 - 0.05 = 4.65
Error interval for x is 4.65 ≤ x < 4.75.

Answer: 10 inches.
Step-by-step explanation:
v=l*w*h
Let’s plug in your numbers:
4,331.25=22.5*19.25*h
Let’s simplify it.
4,331.25=433.125*h
Then divide both sides by 433.125 (.125=1/8 by the way).
