Answer:
a=10
Step-by-step explanation:
The question can be interpreted as
F∝a
If we introduce proportionality constant k, we have
F= k.a
28= k. 7
k= 28/7
k= 4
Then the equation can be written as
F= 4.a
To find, a when F = 40?
F= 4.a
40=4 × a
a= 40/4
a= 10
Square root of 25 rounded to the nearest tenth
Write an explicit formula for An, the nth term of the sequence 33, 36, 39,
Answer:
30 + 3n
Step-by-step explanation:
33 , 36 , 39 .......
This is an arithmetic series
First term = 33
Common difference (d) = Second term - first term
= 36 - 33 = 3
Nth term = a + (n -1)* d
= 33 + ( n-1) * 3
= 33 + n*3 - 1*3
= 33 + 3n - 3
= 33 - 3 + 3n
= 30 + 3n

Answer:
a) Area of sector TRV = [tex] 42.4\: units^2 [/tex]
b) [tex] 0.8\: units[/tex]
Step-by-step explanation:
a)
In [tex] \odot R[/tex], TW is diameter.
Therefore,
[tex] m\widehat {TVW} = 180\degree [/tex]
[tex] \because m\widehat {TV} +m\widehat {VW} =m\widehat {TVW} [/tex]
[tex] \therefore m\widehat {TV} +120\degree =180\degree [/tex]
[tex] \therefore m\widehat {TV} =180\degree - 120\degree [/tex]
[tex] \therefore m\widehat {TV} = 60\degree [/tex]
[tex] \because m\angle TRV=m\widehat{TV} [/tex]
(Measure of central angle is equal to the measure of its corresponding arc)
[tex] \therefore m\angle TRV\:(\theta) =60\degree [/tex]
Radius (r) = RW = 9 units
Area of sector TRV
[tex] =\frac{\theta}{360\degree}\times \pi r^2 [/tex]
[tex] =\frac{60\degree}{360\degree} \times 3.14\times 9^2 [/tex]
[tex] =\frac{1}{6} \times 3.14\times 81 [/tex]
[tex] =\frac{1}{6} \times 254.34 [/tex]
[tex] =42.39\: units^2 [/tex]
Area of sector TRV[tex] =42.4\:units^2 [/tex]
b)
Length of [tex] \widehat{VW} [/tex]
[tex] =\frac{120\degree }{360\degree} \times 2\pi r [/tex]
[tex] =\frac{2}{3} \times 3.14\times 9 [/tex]
[tex] =2 \times 3.14\times 3 [/tex]
Length of [tex] \widehat{VW} [/tex] [tex] = 18.84\: units [/tex]
[tex] \overline{TW} =2*RW =2*9 = 18\: units[/tex]
[tex] \widehat{VW}- \overline{TW}= 18.84-18=0.84\: units[/tex]
[tex] \widehat{VW}- \overline{TW}= 0.8\: units[/tex]

Nicki and june win some money and share it in the ratio 5:3 buck gets £26 more than june how much did june get
Answer:
£39
Step-by-step explanation:
Given data
The sharing formula is
5:3
Let June get £x
Buck gets £26 more than june
Buck = x+26
Applying the part to part ratio method
5/3= x+26/x
cross multiply
3(x+26)= 5x
3x+78= 5x
78= 5x-3x
78= 2x
x= 78/2
x= £39
Hence June get £39
Evaluate the numerical expression 4(8 - 2) = (-3) + 7
Answer:
4 ( 8 - 2 ) = (-3) + 7 -> this is a false statement
Step-by-step explanation:
4 ( 8 - 2 ) = ( -3 ) + 7
Simplify the parenthesis
4 ( 6 ) = (-3) + 7
Multiply;
24 = (-3) + 7
Add, remember, adding a negative number and a positive number is the same as subtracting the negative number from the positive number,
24 = 4
This statement is not true.
An employee compiled sales data for a company once each
month. The scatter plot below shows the sales in multiples of
$1000) for the company over time (in months). The equation
represents the linear model for this data
y = 0.94x + 125
According to the model, how much do the company's sales
increase per month?
$940
$1250
$5000
$9400
$12,500
Answer:sales aer in multipules of 1000
normally the output is y and input is x
input would be number of months
output would be the sales
so
subsitute 40 for x
y=0.94*(40)+12.5
y=37.6+12.5
y=50.1
this is in thousands
times 1000
$50,100 is the sales after 40 months

1. Define "Conjugate radical binomials."
Step-by-step explanation:
For a+b, it's a−b. A conjugate is a binomial where the second term is the opposite of the second term of another binomial. In other words, if I have the expression a+b, the conjugate of my expression is a−b. If I were to add the second terms of these two expressions, I would get 0.

During 2021, equipment was sold for $470000. The equipment cost $782000 and had a book value of $439000. Accumulated Depreciation—Equipment was $2062000 at 12/31/20 and $2211000 at 12/31/21. Depreciation expense for 2021 was:
Answer:
$149,000
Step-by-step explanation:
Subtract acc depreciation for 2020 from acc deprecitation in 2021 and it gives you the depreciation expense solely for 2021.
The Equipment was purchased during 2021 at $1,402,000.
What is Accumulated Depreciation?The total amount of depreciation applied to an asset up to a particular point is known as accumulated depreciation. The beginning cumulative depreciation balance is increased with each period's depreciation expense.
Given:
Equipment purchased during 2021
= Cost of equipment on 12/31/2021 - (Cost of equipment on 12/31/2020 - Cost of equipment sold)
= $2211000 - ( $2062000 - $470000)
= $2211000 - 15,92,000
= $6,19,000
Hence, the Equipment purchased during 2021 at $1,402,000.
