Answer:
Step-by-step explanation:
10)a) Let the number = x
4x + 8 = 16
Subtract 8 form both sides
4x + 8 - 8 = 16 - 8
4x = 8
Divide both sides by 4
4x/4 = 8/4
x = 2
The number is 2
b) Let the number = x
4x - 8 = 6
Add 8 to both sides
4x - 8 + 8 = 6 + 8
4x = 14
Divide both sides by 4
4x/4 = 14/4
x = 3.5
The number is 3.5
11) a) Increase in cost = 105 - 100 = $ 5
b) Percentage increase = [tex]\frac{5}{100}*100[/tex]

12) Number of girls = 35
Number of girls wearing glasses = 15
Number of boys = 40
Number of boys wearing glasses = 10
a) Percentage of boys wearing glasses = [tex]\frac{10}{40}*100\\[/tex]
= 25%
b) Percentage of girls wearing glasses = [tex]\frac{15}{35}*100[/tex]
= 42.86%
c) Total children = 35 +40 = 75
Total children wearing glasses = 15 + 10 = 25
Percentage of children wearing glasses = [tex]\frac{25}{75}*100[/tex]
= 33.33%

Answer:
Step-by-step explanation:
45=5*3^2
75=5^2*3
1. LCM=product of the common and uncommon prime factors at the biggest power
LCM=3^2*5^2=9*25=225
2. HCF= product of the common prime factors at the lowest power
HCF=3*5=15
3. 10*x-3
4. 6^2-7^2=36-49=-13
5. I. K=4-1=3 drinks
II. Total=4+3=7 drinks
6. You will draw exact as inthe drawing with dimensions l=8 cm,h=3cm, w=4 cm
Answer:
Step-by-step explanation:
LCM of two numbers is the smallest number that is evenly divisible by the two numbers
1) 45 = 3 * 3 * 5 = 3² * 5
75 = 3 * 5 * 5 = 3 * 5²
LCM = 3² * 5² = 9 *25 = 225
LCM = 225
2) HCF of two numbers is the greatest number which divides each of them exactly.
HCF of 45 and 75 = 3*5 = 15
HCF = 15
3) 10x - 3
4) m² - n² = 6² - 7²
= 36 - 49
= -13
m² - n² = -13
When two numbers are in different sign, subtract and the result will have the sign of the bigger number.

The population of Watesville decreases at a rate of 1.6% per year. If the population was 62,500 in 2014, what will it be in 2020?
Answer:
56,735 people
Step-by-step explanation:
We can set up an equation to model this:
The equation for exponential decay is y = C(1 - r)^t, where C is the original amount, r is rate of change, and t is time.
We can plug in the corresponding values and solve:
y = 62500(1 - 0.016)^6
y = 62500(0.984)^6
y = (62500)(0.9077)
y = 56,734.94, which we can round to 56,735 people

Mrs. Carlyle bought a bag of nuts for her children. Phillip, Joy, Brent, and Preston took some from the bag.Phillip took 1/3. Joy took 1/4 of the remaining nuts. Brent took 1/2 of the remaining peanuts.Preston took 10. There were 71 remaining in the bag. How many peanuts were oringinally in the bag? How many peanuts did each child take?
Answer:
Originally there was 324 nuts in the bag.
Phillip took 108, Joy took 54, Brent took 81 and Preston took 10.
Step-by-step explanation:
Let's call the total amount of nuts N, and the number of nuts each child took by the initial of their name (Phillip will be P1 and Preston will be P2).
So we can write the following equations:
P1 = N/3
After removing N/3, the remaining nuts is (N - N/3):
J = (N - N/3)/4 = (2N/3)/4 = N/6
After removing N/6 from (N - N/3), the remaining nuts is (N - N/3 - N/6):
B = (N - N/3 - N/6)/2 = (N/2)/2 = N/4
P2 = 10
In the final there were 71 nuts remaining, so we have that:
N - N/3 - N/6 - N/4 - 10 = 71
N - N/3 - N/6 - N/4 = 81
N/4 = 81
N = 324 nuts
The amount of nuts took by each child is:
P1 = N/3 = 108 nuts
J = N/6 = 54 nuts
B = N/4 = 81 nuts
P2 = 10 nuts
Solve the equation 2x + 10 = 30

When solving a system of equations, Jared found y = x + 10 for one equation and substituted x + 10 for y in the other equation. Nicole found x = y – 10 for the same equation and substituted y – 10 for x in the other equation. Who is correct? Explain
Answer:
They are both correct.
Step-by-step explanation:
As we can see, it does not matter whether you plug in x or y in a system of equatins. One thing somebody might be skeptical about in this equation is that one of the equations does not contain a variable. BUT, if reading closer, one can see that both x and y have to be in one of the equations to make the other true.
Hope this helped!
We will see that both Jared and Nicole are correct.
Working with systems of equations:
So we know that Jared found an equation:
y = x + 10, then he substituted y for (x + 10) on the other equation, this would be the substitution method, and Jared is correct so far.
We also know that Nicole found the equation:
x = y - 10
And she replaced x by y - 10 on the other equation, she is also correct.
So why both of them are correct?Each one just substituted a different variable, that is why they have different approaches, but in both cases the substitutions are correct.

Ella has twelve cards numbered I to 12. What is the probability she picks three even-numbered cards in a row, if the first two cards are not replaced?
Answer:
1/11Step-by-step explanation:
even #s between (or including) 1 and 12:
2, 4, 6, 8, 10, 12
there are 6
6/12 for the first one
5/11 for the second one (one even # less)
4/10 for the third one
To find the probability of picking three even numbers from 1 to 12 in a row three times:
multiply the probabilities together:
(6/12)*(5/11)*(4/10)=(24/120)*(5/11)=(12/60)*(5/11)=(1/5)*(5/11)=5/55=1/11

Find the volume pls
Answer:
V = 960 cm ^3
Step-by-step explanation:
The volume is given by
V = Bh where B is the area of the base
B = 1/2 bh since the base is the triangle
B = 1/2 *12*8 =48
V = 48 * 20
V = 960 cm ^3
Answer:
960 cm^3
Step-by-step explanation:
volume of prism = (area of base) * (height of prism)
This is a triangular prism, so the base is a triangle.
area of base of prism = area of triangle = bh/2
The base of the triangle is 12 cm. The height of the triangle is 8 cm.
The height of the prism is 20 cm.
volume = (12 cm)(8 cm)/2 * 20 cm
volume = 960 cm^3

Step-by-step explanation:
This sentence isn't always true.

What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 12*2 = 24
We have been that conjecture "The product of two positive numbers is always greater than either number."
As per the given condition,
For example: 4 × (1/2) = 2 < 4
Therefore, the product of two positive numbers is less than either number i.e. 2 < 4.
Hence, the above counterexample shows that the conjecture is false.

Answer:
A =256 cm^2
Step-by-step explanation:
The perimeter of a square is 64 cm
P = 4s where s is the side length
64 = 4s
Divide by 4
64/4 = 4s/4
16 =s
The side length is 16 cm
The area of a square is
A = s^2
A = 16^2
A =256 cm^2
Answer:
16
Step-by-step explanation:
Perimeter=64
Since there are four sides, we divide 64 by 4
64/4=16
1 side = 4 cm
Area = l x w
4 x 4 = 16
Therefore your area of the square is 16

Answer:
False
Step-by-step explanation:
A definition produces out of nothing a new mathematical entity. But a theorem utilizes some relation between previously defined mathematical entities.

Step-by-step explanation:
You know the short side of an isosceles right triangle is 1/√2 times the hypotenuse. So, the hypotenuse of the 30°-60°-90° right triangle is ...
6/√2 = (6√2)/2 = 3√2
You also know the short leg of a 30°-60°-90° right triangle is half the length of its hypotenuse, so ...
x = (1/2)(3√2)
x = (3/2)√2
_____
Additional comment
For many trig and geometry problems, it is useful to remember the ratios of side lengths for "special" right triangles:
isosceles right triangle: 1 : 1 : √2
30°-60°-90° triangle: 1 : √3 : 2 (shortest to longest)
This knowledge usefully relates to the trig function values for these "special" triangles.
Answer:
3/√2 or 3√2/2
Step-by-step explanation:
Bigger triangle has internal angles 45/45/90, so the legs have equal length and = 6/√2 as hypotenuse = 6
Smaller triangle has hypotenuse of 6/√2 and the angle against leg x is 30°
As we know the leg opposite to 30° angle is half the hypotenuse, so
x= 1/2*6/√2= 3/√2= 3√2/2
