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 = 0.68xCorrect38- Blank:_____=12c+4+3c
Answer:
38-15c-4
Step-by-step explanation:
38-x=12c+4+3c
38-x=15c+4
x=38-15c-4

"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]

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

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

Answer:
Note that the tangents to the circles at A and B intersect at a point Z on XY by radical center. Then, since∠ZAB=∠ZQA and ∠ZBA=∠ZQB. ∠AZB+∠AQB=∠AZB+∠ZAB+∠ZBA=180°. ∴ZAQB is cyclic.But if O is the center of w, clearly ZAOB is cyclic with diameter ZO, so ∠ZQO is 90° ⇒Q is the mid-point of XY.Then, by Power of a Point, PY· PX = PA · PB = 15 and it is given that PY+PX = 11. Thus,PX=(11±[tex]\sqrt{61}[/tex])/2. So, PQ=[tex]\frac{\sqrt{61} }{2}[/tex], PQ²=[tex]\frac{61}{4}[/tex]. Thus, the answer is 61+4=65.

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.

Mike discovered that the pool in his backyard is leaking slowly. The pool holds 17,897 gallons of water, and is leaking at a rate of 5 gallons per day. If Mike does not replace the water that has leaked from the pool, how many gallons of water will remain in the pool after 187 days?
Answer:
Gallons of water remaining = 16,962 gallons
Step-by-step explanation:
Total capacity of the pool = 17,897 gallons
Rate of leakage per day = 5 gallons
Number of days = 187 days
how many gallons of water will remain in the pool after 187 days?
Gallons of water remaining = Total capacity of the pool - (Rate of leakage per day × Number of days
= 17,897 - (5 × 187)
= 17,897 - 935
= 16,962 gallons
Gallons of water remaining = 16,962 gallons
