Step-by-step explanation:
number of shirts = x
price of shirts made = 9x+20
amount u earn by selling the shirts = 15x
profit = 15x - (9x+20)
profit of at least 150,
15x - (9x+20) ≥ 150
Find the 7th term of the geometric sequence shown below
10x^3, 40x^8, 160x^13,…
Answer:
[tex]a_7=40960x^{33}[/tex]
Step-by-step explanation:
Geometric sequence has explicit form:
[tex]a_n=a \cdot r^{n-1}[/tex] where [tex]a[/tex] is first term and [tex]r[/tex] is the common ratio.
First term here is [tex]a=10x^3[/tex] and [tex]r[/tex] could be found by doing second term divided by first term, [tex]\frac{40x^8}{10x^3}=4x^5[/tex].
Therefore the [tex]n[/tex]th term is given by
[tex]a_n=10x^3 \cdot (4x^5)^{n-1}[/tex].
So the [tex]7[/tex]th term is given by
[tex]a_7=10x^3 \cdot (4x^5)^{7-1}[/tex].
Let's simplify:
[tex]a_7=10x^3 \cdot (4x^5)^{7-1}[/tex]
[tex]a_7=10x^3 \cdot (4x^5)^{6}[/tex]
[tex]a_7=10x^3 \cdot (4^6(x^5)^6)[/tex]
[tex]a_7=10x^3 \cdot (4096x^30)[/tex]
[tex]a_7=40960x^{33}[/tex]
What is the square root of 81 as a fraction?
Answer: 9/1
Step-by-step explanation:
round off 7284 to 1sf
Answer:
7000
Step-by-step explanation:
This is because when you round to the significant figure, you basically look at any digits at the start of the number, which isn't zero. In this case, it would be in the thousands place 7284. So you round 7284 to the nearest thousands, which, would be 7000

Answer:
19, 25, 32
Step-by-step explanation:
Find the difference within each number:
5 -> 7: + 2
7 -> 10: + 3
10 -> 14: + 4
With each difference, + 1 is added so we can infer the next difference will be + 5.
14 + 5 = 19
Next is + 6.
19 + 6 = 25
Now + 7.
25 + 7 = 32
A banquet room has been set up with 10 tables that each have 8 seats. If 78 people show up for the banquet, how many empty seats will there be?
There would be 2 empty seats.
Explanation:
If we multiply 10x8 we would get 80. If 78 people show up, we would subtract 78 from 80 and our answer would be two.
What load can be lifted by an effort of 800N if the effort arm is 80cm and the load arm is 20cm?
Step-by-step explanation:
Solution,
Effort=800N
Effort arm=80 cm
Load arm=20 cm
Load=?
Now,
by the principle of lever, we have
Load×Load arm=Effot×Effort armLoad×20=800×80Load=800×80/20Load=3200 NSo, the load of 3200N can be lifted .
Answer:
load (l) =?
LOAD ARM = 20 CM
EFFORT ( E)= 800N
EFFORT ARM = 80cm
load *load arm = effort *effort arm
l*20 cm = 800 *80
L = 64000/20
answer = 3200
How do you simplify 5 to the 3 power times 25
Answer:
5^5
Step-by-step explanation:
5^3 * 25
Note that 25 = 5^2 (which is 5 * 5)
so we can rewrite the first expression as
5^3 * 5^2
We can add the exponents because we are multiplying and there is the same base (5):
5^(3+2) = 5^5

f: M ⇒ N is a function from M to N.
Given,
f: M ⇒ N
We need to describe this mathematical statement in our own words.
What is a function?A function is defined as a way where there is an input that it takes and produces an output.
The set from where the inputs come is called the Domain.
The set of outputs is called the Range.
We have,
f: M ⇒ N
Here
f is a function that takes input from the set M and its output belongs to set N( Natural number).
Here,
M is called the domain.
N is called the codomain.
Thus f: M ⇒ N is a function from M to N.

a fruitseller bought 50 kg of fruits. he sold 30 kg of fruits for the cost price of 35 kg of fruits and he sold the remaining quantity for the cost price of 16 kg of fruits. calculates his profit and loss percent in the total transactions
Step-by-step explanation:
let the price of fruits be X per kg
cp of 50kg of friuts =50x
he sells 30kg of fruits on its cp of 35 kg
cp of 30kg fruits=30x
sp of 30kg fruits=35x
remaing fruits is 20kg
he sells 20kg of fruits on cp of 16kg
cp of 20kg fruits=20x
sp of 20kg fruits =16x
total cp is =50x
total sp is =(35+16) =51x
sp>cp(it means profit)
profit =sp-cp
=51-50
= 1
profit%=gain/cp × 100
= 1/50×100
=2%

This chart shows the temperature recorded at noon for some world cities . Which two cities had different of 25°c
Answer: London and Moscow.
Step-by-step explanation: This problem is simple. First, we use process-of-elimination. None of the positive values have a difference of 25 degrees, so one of the two values must be -12 degrees aka Moscow. From there, we add 25 to -12 to get 13. This means that the other city is London since it is 13 degrees.

Two mechanics worked on a car. The first mechanic worked for 10 hours, the second mechanic worked for 5. Together they charged a total of 950$ What was the rate charged per hour by each mechanic if the sum of the two rates was 125$ per hour?
Answer:
Step-by-step explanation:
Let x = the hourly rate of the first mechanic and
y = the hourly rate of the second mechanic.
As far as the equation goes for the total amount charged:
10x + 5y = 950
As far as the equation goes for the sum of the 2 mechanics' rates:
x + y = 125
Solve the first equation for either x or y. I solved for y:
y = 125 - x
Now plug that into the first equation for y to get:
10x + 5(125 - x) = 950 and
10x + 625 - 5x = 950 and
5x = 325 so
x = 65
The first mechanic charges $65 per hour and the second mechanic charges
y = 125 - 65 so
the second mechanic charges $60 per hour.

What is mean by graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
Now,
We know an exponential function is a function in which the independent variable is the exponent.
One such function is y = eˣ
Now, To graph an exponential function you come up with values to use in the graph should be a T-chart using random values for x and y.
As it would result in graphing the complete nature of the function.
