Explanation:
If the amount of change due to rounding is the same for both numbers, the original difference and the difference of rounded values will be the same. This will always be the case if the hundredths digits are the same to start with.
Example:
A = 0.56 ⇒ C = 0.6
B = 0.66 ⇒ D = 0.7
__
B - A = 0.66 -0.56 = 0.10
D - C = 0.7 -0.6 = 0.10 . . . . . same as B - A, ∴ Dominic is incorrect.

PLEASE HELP::::::: Triangle PQR has medians QM and PN that intersect at Z. If ZM= 4, find QZ and QM
HELP HELP
Answer:
value of QZ = 8 units and QM = 12 units.
Step-by-step explanation:
Given: In triangle PQR has medians QM and PN that intersect at Z.
If ZM = 4 units.
In the figure given below; second median divided the two triangles formed by the first median in the ratio 2:1.
We have to find the value of QZ and QM;
QZ:ZM = 2: 1
⇒
Substitute the value of ZM =4 units and solve for QZ;
Multiply both sides by 4 we get;
Now, calculate QM;
QM = QZ+ZM = 8 + 4 = 12 units.
Therefore, the value of QZ and QM are; 8 units and 12 units

Answer:
combined means to add so you are going to add anything over 1 because it says longer than 1
1 1/4 has 2 marks so you add 1 1/4 + 1 1/4 =
they have like denominators so you can add them together
1 + 1 = 2 and 1/4 + 1/4 = 2/4 which can be reduced to 1/2
so your answer is 2 1/2

(urgent please help!!!!)in computing the mean of 8 numbers, a student mistakenly used 17 instead of 25 as one of the numbers and obtained 20 as the mean. find the correct mean.
Answer: 21
Step-by-step explanation:
The student's mean of the 8 numbers is 20; the total of the numbers will be
8 x 20 = 160
If we take out the 17 the total will be 160 - 17 = 143
If we then replace the 17 with 25 the total rises to 168.
168 divided by 8 = 21
Consider the following equation.
x – 0.32x = 0.68x
Which of the following statements matches the mathematical equations?
Question 5 options:
a) Decrease a number by 0.32 is the same as multiplying by 0.68.
b) Decrease a number by 32% is the same as increasing by 68%.
c) Decrease a number by 0.32 is the same as multiplying by 0.32.
d) Decrease a number by 32% is the same as multiplying by 68%.
Answer:
d) Decrease a number by 32% is the same as multiplying by 68%Step-by-step explanation:
Given equation:
x - 0.32x = 0.68xOptions (4 of them given)
a) Decrease a number by 0.32 is the same as multiplying by 0.68.
x - 0.32 = 0.68x ⇒ 0.32x = 0.32Incorrectb) Decrease a number by 32% is the same as increasing by 68%.
x - 32% = x + 68% ⇒ 0 = 100%Incorrectc) Decrease a number by 0.32 is the same as multiplying by 0.32.
x - 0.32 = 0.32x ⇒ 0.68x = 0.32Incorrectd) Decrease a number by 32% is the same as multiplying by 68%
x - 32% = 0.68x ⇒ x - 0.32x = 0.68x ⇒ 0.68x = 0.68xCorrectWhich equation is NOT equivalent to p- 7 = 22? Select all that apply.
A. p-p-7 = 22-p
B. p-7-p = 22 -
C. p - 7 + 22 = 22 - 7
O
D. p - 7 + 7 = 22 - 22
Ep-7 + 7 = 22 +7

Three more than the product of 3 and a number is less than 18
Answer:
x < 5
Step-by-step explanation:
Mark the number as x
Then 3x + 3 < 18
// divide both sides by 3
x + 1 < 6
x < 6 - 1
x < 5

Syrus is buying a tent with the dimensions shown below. The volume inside the tent is 4.5\text{ m}^34.5 m 3 4, point, 5, start text, space, m, end text, cubed. Syrus isn't sure if the tent will be tall enough for him to stand inside.
Answer:
2 meters
Step-by-step explanation:
Given
[tex]Volume = 4.5m^3[/tex]
The question is incomplete as the picture of the tent is not attached.
However, I will use the attached figure to answer the question.
From the attachment, we have:
[tex]b = 1.5m[/tex] --- base of the tent
[tex]l = 3m[/tex] --- length of the tent
Required
Determine the height of the tent
The volume of the tent is:
[tex]\frac{1}{2} * bhl = Volume[/tex]
Where h is the required height.
So, we have:
[tex]\frac{1}{2} * 1.5 * h * 3 = 4.5[/tex]
[tex]\frac{1}{2} * 1.5 * 3 * h = 4.5[/tex]
[tex]\frac{1}{2} * 4.5 * h = 4.5[/tex]
Make h the subject
[tex]h = \frac{4.5 * 2}{4.5}[/tex]
[tex]h = 2m[/tex]
The height of the tent is 2m
Answer:
2 meters
Step-by-step explanation:
We can use the volume formula, V = 1/2 bhl
⋅1.5⋅h⋅3
=2.25h
=h
The height of the tent is 2 meters.

Establece el producto cartesiano;representa en diagrama sagital y plano cartesiano M={a,b,c} N={4,8,12} ayuda
Answer:
-30
Step-by-step explanation:
The product of M x N is {4a + 8b + 12c}.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given are the matrices as -
M = {a, b, c} and N = {4, 8, 12}
We can write the product as -
M x N = {4a + 8b + 12c}
Therefore, the product of M x N is {4a + 8b + 12c}.

The enrollment at Temple Junior High School has a change of ─ 60 over a 3 year period. What is the average change per year?
Answer:
- 20
Step-by-step explanation:
Total Change in enrollment = - 60
Period of time at which change occurred = 3 years
Average change per year :
Total change in enrollment / period at which change occurred
= - 60 / 3
= - 20
Average change of - 20 enrollments per year
Mrs. Neville is baking five batches of cookies. She will need 2 \frac{1}{2} 2 1 cups of flour for each batch of cookies. If she begins with a 20 cup bag of flour, what is the resulting change in the amount of flour in the bag?
Answer:
12.5 cups used
7.5 cups left
Step-by-step explanation:
Number of batches = 5
Cups of flour per batch = 2 1/2 cups
Initial amount of flour = 20 cup bag
After 5 batches ; number of cup used :
5 * 2 1/2 = 12.5 cups of flour
Change in amount of flour in bag :
(20 cups - 12.5 cups) = 7.5 cups
Target is having a huge winter season sale on all of their televisions. A 42in screen tv that usually retails at $580 is marked down by 20%. If you brought $450 to the store, do you have enough money to buy the tv? Explain your reasoning.
Answer: You do not because the tv costs $464.
Step-by-step explanation:
First find out how much 20% of 580 is:
= 20% * 580
= $116
The television was therefore marked down by $116. The current selling price is:
= 580 - 116
= $464
Since you came with $450, you will not be able to buy the television as you would be short of the $464 required.
"Dan" uses 2/3 cup of brown sugar and 1/4 cup of white sugar to make oatmeal bars. How many cups of sugar does he use in all?
Answer:
the number of cups of sugar he use in all is [tex]\frac{11}{12}[/tex]
Step-by-step explanation:
The number of cups does he use in all as follows:
= Brown sugar + white sugar
[tex]= \frac{2}{3} + \frac{1}{4}\\\\= \frac{8 + 3}{12} \\\\= \frac{11}{12}[/tex]
Hence, the number of cups of sugar he use in all is [tex]\frac{11}{12}[/tex]

Answer:
x = 5*sqrt(2)
y = 5*sqrt(2)
Step-by-step explanation:
Because the triangle is a 45-45-90 triangle, 10 is equal to x * sqrt(2) and x = y.
x = 10 / sqrt(2)
When simplified:
10 / sqrt(2) = (10 * sqrt(2)) / 2 = 5 * sqrt(2)
