20% of all the children in a class are left handed.
4 children are left handed.
How many children are there in the class altogether?
Answer:
There are 20 students in the class
Step-by-step explanation:
Let the total number of children in the class be = x
from the question, we know that 20% of all the children are left-handed. We also know that 20% of the total children in the class = 4.
This means that 20% of x = 4
Wherever we see the word "of" in an arithmetic problem, we should know that it infers a multiplication there.
Hence, we have
[tex]\frac{20}{100} \times x = 4[/tex]
[tex]x = \frac{4 \times 100}{20}= 20[/tex]
There are 20 children in the class altogether

Given the graph that is shown. What is the range of the function??!
Answer:
[tex]-3\leq x[/tex] < 6
third answer choice
Step-by-step explanation:
On a coordinate plane, point AS
located at(74) and point Bis
located at 8.41 What is the
distance between the two points?
Answer:
√1370 or about 37.01
Step-by-step explanation:
use distance formula
√(x2-x1)^2+(y2-y1)^2
sqrt(8-7)^2+(41-4)^2
sqrt(1)^2+(37)^2
sqrt 1+1369
sqrt 1370
= about 37. 01

In Tampa the number of new houses built each month during the first half of the year decreased at a constant rate. During the second half of the year the number of new houses remained the same. Which graph best illustrates the numbers of houses built over the course of the year? 1l
Answer:
D or C I believe
Step-by-step explanation:
it says it was going down and then it stayed the same, but what confuses me is that the bottom says "month" so I cant tell now if its an error or its telling us it is still going down during the month year (C) so yeah good luck :,)

What is the solution set for the inequality below
-3x + 15 < 18
Answer:
x > -1
Step-by-step explanation:
-3x + 15 < 18
Subtract 15 from each side
-3x + 15-15 < 18-15
-3x < 3
Divide each side by -3, remembering to flip the inequality
-3x/-3 > 3/-3
x > -1

7x-6y=9
5x+2y=19 Solve the system using elimination.
Step-by-step explanation:
multiply 5x+2y=19 by 3 youll get 15x+6y=57
eliminate y
7x-6y=9
15x+6y=57 +
22x=66
x=3
substitute x to 5x+2y=19
15+2y=19
2y=4
y=2

a bed of a pickup truck measures 4 ft by 8 ft to the nearest inch what is the length of the longest thin metal bar that will lie flat in the bed
Answer:
11 ft 3 in
Step-by-step explanation:
The bed of a pickup truck measures 4 feet by 8 feet. To the nearest inch, what is the length of the longest thin metal bar that will lie flat in the bed? 11 ft 3 in.
Answer:
Step-by-step explanation:
the diagonal is the longest so use Pythagoras
c^2 =a^2 + b^2
c^2=4^2+8^2
c^2=16+64
c =[tex]\sqrt{80}[/tex]
c = 8.944 ft
Colin buys a tv for £780.
It depreciates at a rate of 5% per year.
How much will it be worth in 6 years?
Give your answer to the nearest penny where appropriate.
Answer:
£573.40
Step-by-step explanation:
Amount = cost price - total depreciation
depreciation (1st year ) = 5% of £780
= [tex]\frac{5}{100}[/tex] x 780
= 0.05 x 780
= £39.00
depreciation (2nd year) = 5% of £741
= £37.05
depreciation (3rd year) = 5% of 703.95
= £35.1975
depreciation (4th year) = 5% of 668.7525
= £33.437625
depreciation (5th year) = 5% of 635.314875
= £31.76574375
depreciation (6th year) = 5% of 603.5491313
= £30.17745656
Total depreciation = £39.00 + £37.05 + £35.1975 + £33.437625 + £31.76574375 + £30.17745656
= £206.6283253
Total depreciation = £206.6283253
Therefore,
Amount after 6 years = £780 - £206.6283253
= £573.3716747
= £573.40
The worth of the TV after 6 years is £573.40.

573.37

Step-by-step explanation:
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share, now when you have a polynomial, the greatest common factor (GCF) of a polynomial is the largest monomial that divides evenly into each term , so
[tex](GCF)\\x^4=x^4\\x^5=x^4.x\\x^7=x^4 x^3\\(GCF)=x^4 \\[/tex]

Craig measured a length as 0.034 millimeters. What is the margin of error? 0.03 mm to 0.04 mm 0.033 mm to 0.034 mm 0.0335 mm to 0.0345 mm 0.0345 mm to 0.0350 mm
C. 0.0335 mm to 0.0345 mm
Step-by-step explanation:
The least significant digit of Craig's measurement is in the 0.001 mm place. The error in the measurement is presumed to fall within half that value either side of Craig's measurement. So, the actual value is expected to be in the range ...
0.034 - 0.0005 = 0.0335
to
0.034 + 0.0005 = 0.0345
The measurement is presumed to be in the range 0.0335 mm to 0.0345 mm.

The function t=f(S) models the time, in hours, for a sample of water to evaporate as a function of the size S of the sample, measured in millimeters. What are the units for f’’(S)?
Given that,
The function is t = f(S).
To find,
The unit of f''(S).
Solution,
The given function shows the time for a sample of water to evaporate as a function of the size S of the sample, measured in millimeters.
f'(S) will be in hours per Mililiter
And
f''(S) will be in hours per Mililiter per Mililiter. Therefore, this is the required solution.
