Three machines are used to produce nails. the table displays the total number of nails produced by the three machines over different lengths of time
Answer:
Step-by-step explanation
they answer would be a whole number because you are multiplying by one thousand
Using the principle of proportionality, the number of nails that will be produced by 1 machine in 1 hour is [tex] 21 \frac{3}{5} \: thousand [/tex]
Let :
Number of machines = mNumber of nails produced = nTime taken = tUsing Principle of variation :
Number of machines α nails produced α 1/time[tex] m = \frac{kn}{t} [/tex] ; where k = constant of proportionalityUsing a row from the table :
t = 15 ; n = 81/5
3 = (81/5)k / 15
Cross multiply :
3 × 15 = (81/5)k
45 = (81/5)k
Divide both sides by (81/5) to isolate k
(45 ÷ 81/5) = k
k = (45 × 5/81) = 25/9 = 2.7777
Substituting the value of k into the expression:
[tex] m = \frac{\frac{25}{9}n}{t} [/tex]
We can use the expression to obtain, the value of n ; when m = 1 and t = (1 hour = 60 minutes)
[tex] 1 = \frac{\frac{25}{9}n}{60} [/tex]
[tex] 60 = \frac{{25}{9}}{n}[/tex]
Divide both sides by 25/9 to isolate n
[tex] 60 \times \frac{9}{25} = n [/tex]
[tex] n = \frac{540}{25} = 21 \frac{3}{5} \: thousand \: nails [/tex]

Given the points a ( -2,4 ) and b(7,-2) find the coordinates of the point p on the directed like segment ab that partitions ab in the ratio 1:2
9514 1404 393
Answer:
p = (1, 2)
Step-by-step explanation:
We want ...
(p -a)/(b -p) = 1/2
2(p -a) = b -p . . . . . cross multiply
3p = b +2a . . . .. . . rearrange
p = (b +2a)/3
p = ((7, -2) +2(-2, 4))/3 = (7 -4, -2 +8)/3 = (3, 6)/3
p = (1, 2)

Emma got 90% of the questions on her history test correct if she answered 27 questions correctly, how many questions did Emma get wrong?
There were (A) questions on the test so she got (B) questions wrong
Answer:
There were 30 questions on the test so she got 3 questions wrong.
Step-by-step explanation:
Given that:
Correct answers by Emma = 27
Percentage of correct answers = 90%
Let,
x be the total number of questions on test
90% of x = 27
[tex]\frac{90}{100}x=27[/tex]
[tex]0.9x=27[/tex]
Dividing both sides by 0.9
[tex]\frac{0.9x}{0.9}=\frac{27}{0.9}\\x=30[/tex]
There were 30 questions on the test.
Wrong answers = Total questions - Correct answers
Wrong answers = 30-27 = 3
Hence,
There were 30 questions on the test so she got 3 questions wrong.

ANSWER TO GET 20 POINTS
Answer:
true
Step-by-step explanation:
which function represents the relationship between x and y when y=16/5 and x=20
Answer:
y = (4/25)x
Step-by-step explanation:
We are given;
y = 16/5 and x = 20
Now if y varies directly with x, then we can say;
y = mx
Where m is constant of proportionality
This means that;
16/5 = 20m
Divide both sides by 20 to get;
(16/5) × 1/20 = m
16/100 = m
m = 4/25
Thus,the equation is:
y = (4/25)x

Write an equation to describe this situation using decimals. “Tessa bought x pounds of almonds. Lark (y) bought more than that”. PLEASE HELP!
Answer:
y = 1.6x
Step-by-step explanation:
y is the total amount/pounds of almonds that Lark bought. x is the amount that Tessa bought. 3/5 is the same as 0.6. If we multiplied Tessa's amount by 0.6 it would decrease by 2/5 so we have to add 1 to make it 1.6. To find how much Lark bought multiply 1.6 and Tessa's amount.

The complete table will be:
x y
1 5
0.8 4
0.4 2
Step-by-step explanation:
Given rule is:
y = 5x
In the given rule, x is multiplied by 5 to get the values of y. The same rule can be manipulated to find the value of x in terms of y.
[tex]\frac{y}{5} = \frac{5x}{5}\\x = \frac{y}{5}[/tex]
Putting y = 5
[tex]x = \frac{y}{5}\\x = \frac{5}{5}\\x = 1[/tex]
Putting y = 4
[tex]x = \frac{y}{5}\\x = \frac{4}{5}\\x = 0.8[/tex]
Putting y = 2
[tex]x = \frac{2}{5}\\x = 0.4[/tex]
Hence,
The complete table will be:
x y
1 5
0.8 4
0.4 2
