1- the diameter of a CD is 24 cm nearest to cm .find its upper and lower bound.
2- if your mass is 57g .your mass could actually be anything between 56.5kg and 57.5kg.do you agree or not explain the reason .why?
3- write 7.875 nearest to a two decimal place.
4- write 2.3242900000 nearest to a two decimal place.
5-divide 180 kd between ahmed ,jasim and Dalal in the ratio of 3:1:5.
answer any one of this questions
Answer:
1) Lower bound = 23.5 cm
Upper bound = 24.5 cm
2) I disagree
3) 7.88
4) 2.32
5) Ahmed = 60 kg
Jasim = 20 kg
Dalal = 100 kg
Step-by-step explanation:
1) diameter = 24 cm was rounded up to the nearest cm.
Now, usually, we round up 0.5 to the next whole number. This means that, the actual diameter is;
23.5 ≤ D < 24.5
Thus;
Lower bound = 23.5 cm
Upper bound = 24.5 cm
2) If you weigh 57g,converting to kg is 0.57 kg.
Now, this does not fall in between 56.5kg and 57.5kg given.
Thus, I disagree that your weight could be anything between 56.5kg and 57.5kg .
3) 7.875 approximated to the nearest two decimal place = 7.88
4) 2.3242900000 to the nearest 2 decimal place = 2.32
5) 180 kd shared between ahmed ,jasim and Dalal in the ratio of 3:1:5.
Total part of ratio = 3 + 1 + 5 = 9
Their respective shares are;
Ahmed = 3/9 × 180 = 60 kg
Jasim = 1/9 × 180 = 20 kg
Dalal = 5/9 × 180 = 100 kg

Austin borrowed money from a credit union for 4 years and was charged simple interest at an annual rate of 5% the total interest that he paid was $160 how much money did he borrow
Given:
Rate of simple interest = 5%
Time = 4 years
Total interest = $160
To find:
The amount borrowed by Austin from a credit union.
Solution:
The formula for simple interest is:
[tex]I=\dfrac{P\times r\times t}{100}[/tex]
Where, P is principal, r is the rate of interest and t is the number of years.
Putting [tex]I=160,r=5,t=4[/tex] in the above formula, we get
[tex]160=\dfrac{P\times 5\times 4}{100}[/tex]
[tex]160=\dfrac{20P}{100}[/tex]
[tex]160=\dfrac{P}{5}[/tex]
Multiply both sides by 5.
[tex]800=P[/tex]
Therefore, Austin borrowed $800 from a credit union for 4 years.

If you roll a single six-sided die, what is the probability of rolling an odd number?
A 1/6
B 1/3
C 1/2
D 3
Please help!
Answer: that means you have a 3/6 chance which can be simplified to 1/2
1, 3 and 5 are the odd numbers
Step-by-step explanation:
Answer:
the answer is c 1/2
Step-by-step explanation:
since there are 6 numbers on the die that range from 1-6, that means there are three odd numbers, so the probability would be 3/6, which can reduce to 1/2

A local shelter is having an Adopt-a-thon for kittens and puppies. Kittens cost $50 to adopt and puppies are $75. The shelter made $1200 during the Adopt-a-thon event and adopted off twice as many puppies as kittens. Write and solve a system to find how many puppies and kittens were adopted
Answer:
Step-by-step explanation:
P=2K
50K+75P=1200, using P from above makes this equation become
50K+75(2K)=1200
50K+150K=1200
200K=1200
K=6, since P=2K
P=2(6)=12
So 12 puppies and 6 kittens were adopted.

y = x + 7
For -1:
y = -1 + 7 = 6
y = 7
(x,y) = ( -1, 7)
For 0:
y = 0+ 7
y= 7
(x,y) = (0,7)
For 2:
y = 2+ 7
y= 9
(x,y) = (2,9)
For 4:
y = 4+ 7
y= 11
(x,y) = (4,11)
The quadrilateral below is a rectangle. Solve for x and m
Answer:
x = 13
∠WZX = 57°
Step-by-step explanation:
Because it is a rectangle, ∠XYZ is 90°
∠XZY + ∠YXZ = 90
(5x - 8) + (x + 20) = 90
simplify:
6x + 12 = 90
subtract 12 from each side
6x = 78
divide both sides by 6
x = 13
∠WZX is complimentary to angle (x + 20)
∠WZX = 90 - (13 + 20) = 57°

Y= -6/5x-7 and y=2/5x+1
Answer:
x = -5
y = -1
Step-by-step explanation:
Y= -6/5x-7 and y=2/5x+1
then:
-6/5x - 7 = 2/5x + 1
simplify:
-8/5x = 8
divide both sides by 8:
-1/5x = 1
multiply both sides by 5:
-x = 5
x = -5
y = 2/5(-5) + 1 = -2 + 1 = -1

110 yards per person
Put back into miles
Everyone ran 0.0625 miles
Which value is a solution to the inequality x 4
Answer:
The answer is D
Step-by-step explanation:
We want to see which of the given values is a solution of the inequality:
x < 4
The correct option is A, x = 3.
Finding the solution:
So the inequality:
x < 4
This means that the variable must be a number smaller than 4.
Then we just need to select the option that is smaller than 4, the only option that meets this requirement is option A, x = 3
Also, as you can see in the number line, the only number that is in the shaded part is x = 3 (from the ones in the options).

On Sunday, the high temperature was 71° F, but on Monday it was 5° F lower. What was the percent change?
Answer:
The percent change is -7%.
Step-by-step explanation:
In order to find the answer, you can use the following formula:
Percent change=(New value-Old value/Old value)*100
New value=71-5=66
Old value=71
Now, you can replace the values on the formula:
Percent change=(66-71/71)*100
Percent change=(-5/71)*100
Percent change=-0.07*100
Percent change=-7%
According to this, the answer is that the percent change is -7%.
