Given:
The area of the squares are given.
To find:
The exact side length or estimate side length of the square.
Solution:
We know that, the area of a square is
[tex]A=a^2[/tex]
Where, a is the side length of the square.
[tex]a=\sqrt{A}[/tex]
Area of the square is 100 square units. So, the side length is:
[tex]a=\sqrt{100}[/tex]
[tex]a=10[/tex]
Therefore, the side length is 10 units.
Area of the square is 95 square units. So, the side length is:
[tex]a=\sqrt{95}[/tex]
It is not exact. We know that [tex]\sqrt{81}<\sqrt{95}<\sqrt{100}[/tex].
Therefore, the side length is between 9 and 10.
Area of the square is 36 square units. So, the side length is:
[tex]a=\sqrt{36}[/tex]
[tex]a=6[/tex]
Therefore, the side length is 6 units.
Area of the square is 30 square units. So, the side length is:
[tex]a=\sqrt{30}[/tex]
It is not exact. We know that [tex]\sqrt{25}<\sqrt{30}<\sqrt{36}[/tex].
Therefore, the side length is between 5 and 6.
Last year the schools newspaper so if full page ad for $16.50 each of H half page is $9.60 each day school they plan to increase the cost of 8 x 50% which expressions represent the total amount the school newspaper will earn from selling the same number of four and half page ad this year
Question isn't well formatted, however. From what can be gathered form the question :
Options are given
Answer:
4(1.5 * 16.50) + (1.5 * 9.60)
$113.40
Step-by-step explanation:
Last year:
Cost of full page ad = $16.50
Cost of half page ad = $9.60
50% increase in ad price this year :
Price, this year :
Full page = 1.50 * 16. 50 = $24.75
Half page = 1.50 * $9.60 = $14.4
Expression :
4(1.5 * 16.50) + (1.5 * 9.60)
Cost of a 4 and 1/2 page ad :
Full page = 4 * $24.75 = $99
Half page = 1 * $14.4 = $14.40
Total cost = $(99 + 14.40) = $113.40
What the volume of a cylinder with a diameter of 6mm and a height of 7 mm.it says it’s 700 something but the only answers on the test are as low as 100 and highest is 230? Help plz
8th grade math*
Answer: 197.82mm³
Step-by-step explanation:
Volume of a cylinder = πr²h
where,
π = 3.14
r = Diameter/2 = 6mm/2 = 3mm
h = 7mm
Volume = πr²h
= 3.14 × 3² × 7
= 3.14 × 9 × 7
= 197.82mm³
The volume of the cylinder is 197.82mm³
I need to find the number between - 2 2/5 and -2 1/10 The possible answers are -3/10, -2 1/2, -1 5/6, -2 1/4 and why.
Answer:
-2 1/4
converting the fraction to decimals
-2 2/5 = -2.4
-2.1 = -2 1/10
-2 1/4 = -2.25
this is between -2.1 and -2.4 on the number line
Step-by-step explanation:
to determine which number is between the numbers specified, convert to fractions
-2 2/5 = -2.4
-2.1 = -2 1/10
-2 1/4 = -2.25
3/10 = -0.3
this is less than -2.1
-21/2 = -2.5
this is greater than -21/4
-15/6 = -1.83
this is less than -2.1
it is only, -21/4 that is between the numbers

Answer:
4026
Step-by-step explanation:
Remember PEMDAS:
P - parenthesis
E - exponents
MD - Multiplication and Division (Left to Right)
AS - Addition and Subtraction (Left to Right)
------------------------
Start off by doing the parenthesis (7.1 x 10-5)
We must perform multiplication first so 7.1 x 10 is 71. From there you subtract 5 so 71 - 5 is 66!
So far we have: 66(6.7 x 10-6)
But we aren't done yet!
You must solve (6.7 x 10-6)
Same goes here, multiplication is done first so we would do 6.7 x 10 which is 67. Next, 67-6 which is 61.
We now have (66)(61)
When there is no sign of multiplication or division and the numbers are next to each other like this, you perform multiplication. So, 66x61 is 4026.
Thus, the answer is 4026!

The Precision Scientific Instrument Company manufactures thermometers that are supposed to give readings of o°C at the freezing point of water. Tests on a large sample of these thermometers reveal that at the freezing point of water, some give readings below O°C (denoted by negative numbers) and some give readings above O C (denoted by positive numbers). Assume that the mean reading is 0°C and the standard deviation of the readings is 1.00°C. Also assume that the frequency distribution of errors closely resembles the normal distribution. A thermometer is randomly selected and tested. A quality control analyst wants to examine thermometers that give readings in the bottom 4%. Find the temperature reading that separates the bottom 4% from the others. Round to two decimal places. A. -1.48B.-1.89 C. -1.63 D. -1.75
Solution :
It is given that the Precision Scientific Instrument company Manufactures thermometers that provide readings at 0 degree Celsius for the freezing point of water.
A quality control analyst examines the thermometers which provide readings in the bottom of 4%.
Using the standard normal table, we get
P(z < z) = 4%
P(z < z) = 0.04
See the probability of 0.04 in the standard normal corresponding to the z-value is = -1.75
Therefore,
P(z < -1.75) = 0.04
z = -1.75
So the temperature reading that separates the bottom of 4% from the other thermometers is - 1.75°C
Therefore correct option is (D). -1.75
what is the value of 11²
Answer: 121
11^2 = 11 x 11 = 121
Answer:
121
Step-by-step explanation:
To square a number, we have to multiply the number by itself. This means we'll multiply 11 by 11.
11 · 11 = 121
So, 11² = 121.

A baseball bat that originally sold for $65 is on sale at a 15% discount. Which single gift card amount would cover the complete cost of the discounted bat? Select all that apply.
A
$10
B
$15
C
$50
D
$60
E
$80
Answer:
A
$10
Step-by-step explanation:
15% of $65 is 9.75
so $10 would cover the given amount
We want to see which card can cover completely the cost of a bat after a discount is applied. We will see that the correct options are:
D and E.
The baseball bat is originally sold for $65.
It has a discount of a 15%, then the new price is given by:
P = $65*(1 - 15%/100%) = $65*(1 - 0.15) = $65*0.85 = $55.25
So the gift cards that cover the whole cost of the discounted bat are these ones with a value equal or larger than $55.25
The correct options are:
D: $60
E: $80
With these two you could pay the complete cost of the discounted bat.

A satellite is 24,400 miles from the horizon of Earth. Earth’s radius is about 4,000 miles. Find the approximate distance the satellite is from the point directly below it on Earth’s surface. The diagram is not to scale.
Answer: There are several information's already given in the question. It will be easier to get the answer, if we write all the details down first.
AB = 13200 miles
AO = 4000 miles
OB = 4000 miles
Let us assume CB = x
Then
(x + 4000)^2 = (13200)^2 + (4000)^2
x = sqrt(13200^2 + 4000^2) - 4000
= 13793 - 4000
= 9793 miles.
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the third option.

Sally found 33 fossils. She found twice as many plant fossils as animal fossils. How many of each type of fossil did she find
Answer:
a = 11
b = 33
Step-by-step explanation:
Given :
Total fossil found = 33
Let :
Number of plant fossil = b
Number of animal fossil = a
a + b = 33
Plant fossil = 2 times number of animal fossil
b = 2a
Put b = 2a
a + 2a = 33
3a = 33
Divide both sides by 3
3a/ 3 = 33/3
a = 11
a + b = 33
11 + b = 33
b = 33 - 11
b = 22
