Answer:
24 and 6 are the 2 numbers
Step-by-step explanation:
let the 2 numbers be x and y , then
x + y = 30 → (1)
y = 4x → (2) [ one number is 4 times the other ]
Substitute y = 4x into (1)
x + 4x = 30
5x = 30 ( divide both sides by 5 )
x = 6
Substitute x = 6 into (2)
y = 4 × 6 = 24
The 2 numbers are 24 and 6

Prove z + z + z + z = 4z. Replace each step with the correct equivalent expression based on the given property or operation. Drag the correct tiles to show the steps in order. z + z + z + z = Step 1 (Multiplicative Identity Property) = Step 2 (Distributive Property) = Step 3 (Addition) = Step 4 (Commutative Property of Multiplication) z • 4 1 + (z • z • z • z) 4z z • 0 + z • 0 + z • 0 + z • 0 z • 1 + z • 1 + z • 1 + z • 1 z • (1 + 1 + 1 + 1) ↓ ↓ ↓
Answer:
Step 1: [tex]z*1+z*1+z*1+z*1=[/tex]
Step 2: [tex]z(1+1+1+1)=[/tex]
Step 3: [tex]z*4=[/tex]
Step 4: [tex]z*4 = 4z[/tex]
Step-by-step explanation:
Given
[tex]z+z+z+z = 4z[/tex]
Required
Match the steps with equivalent properties
Step 1: Multiplicative Identity Property
This states that:
[tex]x = 1 * x[/tex]
So, the expression becomes:
[tex]z*1+z*1+z*1+z*1=[/tex]
Step 2: Distributive Property
This states that:
[tex]ab + bc = b(a+c)[/tex]
So, the expression becomes
[tex]z*1+z*1+z*1+z*1=[/tex]
[tex]z(1+1+1+1)=[/tex]
Step 3: Addition
Here, we simply add the expressions in the bracket
[tex]z(1+1+1+1)=[/tex]
[tex]z(4) =[/tex]
[tex]z*4=[/tex]
Step 4: Commutative Property of Multiplication
This states that:
[tex]ab=ba[/tex]
So, we have:
[tex]z*4=[/tex]
[tex]z*4 = 4*z[/tex]
[tex]z*4 = 4z[/tex]

what is -60 ÷_______ = 12
Answer:
5 is the answer.
60÷5=12 as 12×5=60
Answer:
-5
Step-by-step explanation:
The equation, -60 ÷ ____ = 12 can be easily reversed to help us find the missing divisor.
To find the missing divisor, we can rewrite the equation as -60 ÷ 12 = ___.
This way, we can find what the quotient (the divisor of the original equation).
-60 ÷ 12 is equal to -5, so therefore the divisor of -60 ÷ ___ = 12 is -5!
So the finished equation would look like this: -60 ÷ -5 = 12!
(To check your work, multiply -5 by 12 to see if it equals -60 :D)

Answer:
Yes
Step-by-step explanation:
25/5 = 5
30/6 = 5
35/7 = 5
40/8 = 5
Since, 25/5 = 30/6 = 35/7 = 40/8 = 5

Renee bought 7 potatoes at the supermarket. The shortest diameter of each, in centimeters, is shown below
Answer:
2, 3, 4
Step-by-step explanation:
Renee bought 7 potatoes at the supermarket. The shortest diameter of each,
in centimeters, is shown below.
2, 3, 4, 4, 6, 6, 7
After Renee used one potato to make dinner, the median diameter of the remaining potatoes was 5 centimeters. Which of these could be the diameter, in centimeters, of the potato Reneetsed?
Solution:
The median of a group of numbers is the middle number when the group of numbers are arranged in a sorted manner, either ascending or descending.
The median of an even group of numbers, is gotten by taken the average of the two innermost numbers.
Given that the diameter of the potato as:
2, 3, 4, 4, 6, 6, 7
Given that after removing one potato, the median of the remaining potatoes was 5 centimeters.
After removing one potato, the remaining would just be 6. 6 is an even number, hence the median would be the average of the 2 middle numbers.
To get 5 cm, it has to be the average between 4 and 6. This is only possible when a potato of diameter 2,3 or 4 is removed.
If potato with diameter 2 is removed, the remaining is 3, 4, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5
If potato with diameter 3 is removed, the remaining is 2, 4, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5
If potato with diameter 4 is removed, the remaining is 2, 3, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5

Nick works two jobs to pay for college. He tutors for $15 per hour and also works as a
bag boy for $8 per hour. Due to his class and study schedule, Nick is only able to work
up to 20 hours per week but must earn at least $150 per week. If t represents the
number of hours Nick tutors and b represents the number of hours he works as a bag
boy, which system of inequalities represents this scenario?
A. t+b = 20
15t + 8b < 150
B. t+b 20
15t + 8b = 150
C. None of the systems shown represent this scenario.
D. t+b = 20
15t + 8b > 150
Answer:The answer is B.
He can't work more than 20 hours so t+b must be less than or equal to 20.
He has to earn $150 so it cannot be less than 150. Theoretically he could earn more, e.g doing 10 hours of each job which equals $230
Therefore t + b less than or equal to 20 15t + 8b greater than or equal to 150

Find the sum of the first 33 terms of the following series, to the nearest
integer.
2,8, 14, ...
Answer:
3234
Step-by-step explanation:
The series is arithmetic with a common difference = d = 6
First we need to find the 33rd term. Use the formula [tex]a_{n} = a_{1} + (n - 1)d[/tex] where n = 33 and [tex]a_{1} = 2[/tex]
[tex]a_{33} = 2 + (33 - 1)6 = 2 + 32(6) = 194[/tex]
Now the formula for the sum of an arithmetic series is [tex]S_{n} = \frac{n(a_{1} + a_{n} )}{2}[/tex]
So, [tex]S_{33} = \frac{33(2 + 194)}{2}[/tex]
= [tex]\frac{33(196)}{2}[/tex]
= 3234

Answer:
1330.5 cm³
Step-by-step explanation:
To find the volume you want to find the area of the circle and then times this by 14 which is the length of the shape
Area of circle = πr²
11 = the diameter so 5.5 = radius
5.5² x π = 121/4 π
times this by 14 to get 1330.464489 cm³
to 1dp = 1330.5 cm³
Answer:
1330cm³ (rounded to 3 s.f.)
Step-by-step explanation:
The formula of finding the volume of a cylinder is: [tex]\pi[/tex] × r² × h
r is the radius of the cylinder, which is also half of the diameter.
You know the diameter is 11cm and the height (h) is 14cm.
Volume of cylinder = [tex]\pi[/tex] × (11÷2)² × 14
= [tex]\pi[/tex] × 5.5² × 14
= [tex]\pi[/tex] × 30.25 × 14
= 423.5[tex]\pi[/tex]
= 1330cm³ (rounded to 3 s.f.)

A number or the product of a number and a variable in an algebraic expression; a number in a sequence is a term?
Answer:
Yes a number in a sequence is a term.
Step-by-step explanation:
Suppose we have three terms n+2 , n+4 and n+6 in the sequence .
These are treated as separate terms .
Suppose we have
n+ 2= 32
n+2-2= 32-2
n= 30
Again if we put
n+4=32
n+4-4= 32-4
n= 28
we get different values of n for the one solution given for all terms which shows that each term is different.
Now
if we have a different solution for each of them then
Putting the values
n+ 2= 32
n+2-2= 32-2
n= 30
Which shows n is constant but still the terms are different as each has a different value.
Hence the given number in a sequence is a different term.
and
n+4=34
n+4-4= 34-4
n= 30

Answer/Step-by-step explanation:
✔️Find BC:
Reference angle = 50°
Opposite = BC
Adjacent = 5 cm
Based on trigonometric ratio, thus:
Tan 50 = BC/5
Multiply both sides by 5
BC = 5 × tan 50
BC = 5.96 cm (to 3 s.f)
✔️Find x:
Reference angle = 38°
Opp = x
Adj = BC = 5.96 cm
Based in trigonometric ratio, thus:
Tan 38 = x/5.96
Multiply both sides by 5.96
x = 5.96 × tan 38
X = 4.66 (3 s.f)
