Answer:
780
Step-by-step explanation:
So when you're adding consecutive numbers like this. 1+2+3...+39. You add 39 and 1. This is 40. 2+38 is 40. This is a pattern. Now, we do 40 multiplied by 39 and this will give you the number 1620. After this you would have to divide this product by 2. The answer will soon be 780.

Point Y is between the points X and Z. If XY = 3x – 4, YZ = 2x + 3,
and XZ = 24. What is the numerical length of YZ? Use mathematics
to justify your reasoning.
Answer: YZ = 13
Point Y is between the points X and Z => XY + YZ = XZ
=> 3x - 4 + 2x + 3 = 24
<=> 5x - 1 = 24
<=> x = (24 + 1) : 5 = 5
with x = 5 => YZ = 2.5 + 3 = 13
Step-by-step explanation:
The length of segment YZ can be found using the segment addition
postulate that specifies the relationship between the segments.
The numerical length of YZ is 13Reasons:
The given location of point Y = Between points X and Z
Length of XY = 3·x - 4
Length of YZ = 2·x + 3
Length of XZ = 24
Required:
The length of YZ
Solution:
XY + YZ = XZ according to segment addition postulate
Therefore;
3·x - 4 + 2·x + 3 = 24
Which gives;
5·x - 1 = 24
5·x = 24 + 1
[tex]x = \dfrac{24 + 1}{5} = 5[/tex]
x = 5
YZ = 2·x + 3
Therefore;
YZ = 2 × 5 + 3 = 13
The numerical length of YZ is 13

why wuld 8/4 be considerd a whole number
Answer:
because 8/4=2
Step-by-step explanation:
4/4=1
8/4=2
it's because the numerator is bigger if it were 6/4 it would be a mixed number but the eight goes in to 4 directly 2 time so therefore it's 2.
Alexander is a stockbroker he earns 11% commission each week last week he sold $7,200 worth of stocks how much money did he make last week in commission
Answer:
Last week Alexander earned $792 in commissions.
Step-by-step explanation:
Giving the following information:
Commission= 11%
Sales= $7,200
To calculate the total commission, we need to use the following formula:
Total commission= commission rate*sales
Total commission= 0.11*7,200
Total commission= $792
Last week Alexander earned $792 in commissions.
Arjun had some chocolates with him. He gave one fourth of them to Arun and one-sixth of them to Varun. Arjun could do so without breaking any chocolate. Which of these could be the number of chocolates Arjun had in the beginning?
Answer:
See Explanation
Step-by-step explanation:
Given
Arun = ¼
Varun = ⅙
Required
Determine the possible initial number of chocolate
The question requires options to work with which are missing; however, I'll explain how to solve and also list out possible options to make use of.
The question says Arjun gave out fractions of his chocolate without breaking an of them; this means that he gave out whole chocolate (i.e. whole number)
So, to solve this, we multiply the fraction given to Arun and Varun.
Any of the options that results in non decimal integer answers the question.
Take for instance, the options are:
a) 8 b) 15 c) 20 d) 48
Option A: 8
Arun = ¼ * 8 = 2
Varun = ⅙ * 8 = 1.33
Option B: 15
Arun = ¼ * 15 = 3.75
Varun = ⅙ * 15 =2.5
Option C: 20
Arun = ¼ * 20 = 5
Varun = ⅙ * 20 = 3.33
Option D: 48
Arun = ¼ * 48 = 13
Varun = ⅙ * 48 = 8
Option D answers the question because other options resulted in decimals for either Arun or Varun or both of them.

The food bill at a restaurant was $56.40. You decide to leave a 15% tip. What is
the TOTAL amount you are paying for the food and tip?
Answer:$64.86
Step-by-step explanation:
Answer:
$8.46 for tip. The total you paid was $64.86 plus tip.
Step-by-step explanation:
1. Why? First, you need to know the percentage to whole to get to your part. PERCENTAGE: 15% WHOLE: $56.40. (A percent is the percentage of a whole, which is the total.) You need to multiply to get the part.
15% times $56.40
2. How to multiply the percentage to whole.
Put the 15 into a fraction. 15/100, then put the fraction into a demail. (15/100=0.15) Now, multiply.
0.15 x 56.40
(You can add your tip and the bill to get the total of money you spend)
~~~Hope this helps~~~ :)

Leo Is Making A cAke for a friends birthday. The recipe tells him to bake the cake at 190* C for 35 minutes. To what temperature in *F should Leo bake the cake.
A. Use the *C formula to solve for F.
C = 5/9(F-32)
B. Use your new formula for *F to find the temperature equal to 190* C
Answer:
A). F = [tex]\frac{9C}{5}+32[/tex]
B). 374°F
Step-by-step explanation:
A). Formula to convert the temperature from degree centigrade to °F is,
C = [tex]\frac{5}{9}(F-32)[/tex]
We have to solve the formula to get the value of F,
9 × C = [tex]9\times \frac{5}{9}(F-32)[/tex]
9C = 5(F - 32)
[tex]\frac{9C}{5}=\frac{5(F-32)}{5}[/tex]
[tex]\frac{9C}{5}=(F-32)[/tex]
F = [tex]\frac{9C}{5}+32[/tex]
B). In this part we have to find the value of 190° C in °F.
From the formula given in part (A),
F = [tex]\frac{9\times 190}{5}+32[/tex]
= 374°
Therefore, 190°C = 374°F

Answer:
Domain: [1, 6]
Range: [1, 7]
General Formulas and Concepts:
Alg I
Domain is the set of x-values that can be inputted into function f(x). Range is the set of y-values that are outputted by function f(x).Step-by-step explanation:
We can find our domain and range from looking from the graph.
Domain
Domain encompasses x-values. According to the graph, the x-values span from 1 to 6. Since both are closed dots, they are included in the domain:
[1, 6] or 1 ≤ x ≤ 6
Range
Range encompasses y-values. According to the graph, the y-values span from 1 to 7. Since both are closed dots, they are included in the range:
[1, 7] or 1 ≤ x ≤ 7
Easy way to remember this: for Domain, look only at the x-axis and for Range, look only for the y-axis.
