Answer:
t = - 24
Step-by-step explanation:
Given t varies inversely as a then the equation relating them is
t = [tex]\frac{k}{a}[/tex] ← k is the constant of variation
To find k use the condition t = 2 when a = - 4
2 = [tex]\frac{k}{-4}[/tex] ( multiply both sides by - 4 )
- 8 = k
t = [tex]\frac{-8}{a}[/tex] ← equation of variation
When a = [tex]\frac{1}{3}[/tex] , then
t = [tex]\frac{-8}{\frac{1}{3} }[/tex] = - 24

3m + 2n + 4;
m = 2 and N =4
D2 + 9k; d = 10 and k =9
3m + 4y x 2 m = 7, y = 10
Answer:
1. 18
2. 181
3. 101
Step-by-step explanation:
They want you to take each equation, and replace the letter with the number they give you after the equation.
3m + 2n + 4; m = 2, n = 4
This becomes
3(2) + 2(4) + 4
We multiply before we add, according to the order of operations. So next, the equation becomes:
6 + 8 + 4
= 18
———-
D^2 + 9k ; D = 10, k = 9
Numbers squared are numbers multiplied by themselves.
(10)(10) + 9(9)
= 100 + 81 = 181
——————-
3m + 4y x 2 ; m = 7, y = 10
3(7) + 4(10) x 2
21 + 40 x 2
Remember, multiplication always comes before addition.
21 + 80 = 101

Find 3[g(4)] if g(x) = -2x + 10
Answer:
6
Step-by-step explanation:
= 3[-2(4) + 10]
= 3(-8 + 10)
= 3(2)
The function is given as g(x) = -2x + 10 then the solution of the 3[g(4)] would be equal to 6.
What is a function?A function is a type of relation, or rule, that maps one input to a specific single output.
Functions that are formed by composing two or more functions in a way that one's output is another's input are called composite functions.
They are also called functions of functions.
We have to find 3[g(4)] if g(x) = -2x + 10
3[g(4)] = 3[-2(4) + 10]
3[g(4)] = 3(-8 + 10)
3[g(4)] = 3(2)
3[g(4)] = 6

Answer:
75 sq units
Step-by-step explanation:
A = lw
l = OP = distance between (9, 6) and (0, -6)
= [tex]\sqrt{(9 - 0)^{2} + (6 + 6)^{2} }[/tex]
= [tex]\sqrt{81 + 144)} = \sqrt{225} = 15[/tex]
w = MP = distance between (-4, -3) and (0, -6)

the pass percentage?
here's the solution,
rumba got 250 marks !!
if she had got 30 more marks then she would had passed the exam,

jerry has a water tank that holds 5 gallons of water. jerry drinks 4 pints of water a day. how many full tanks of water will he drink in 30 days?
Answer:
3
Step-by-step explanation:
first of all, 8 pints=1 gallon
multiply 4 by the number of days which is 30 so you get 120. then divide by 8 (pints) to find the number of gallons. you come out with 15 gallons. each tank has 5 gallons, so 15 divided by 5 is 3.
Tasneem has a sample of 12 bags of candy. She recorded the mass, in grams, of each bag. Her data is shown.
Answer:
the answer is D
Step-by-step explanation:
The Dot plot for Alia's Sample is plot D.
What is Dot plot?Based on the values of each point, a dot plot visually groups the number of data points in a data set. Similar to a histogram or probability distribution function, this provides a visual representation of the data distribution.
Tasneem has a sample of 12 bags of candy.
Now, the median for Tasneem sample space is
= (47.1 + 47.2)/ 2
= 47. 15
As, the median mass in A is 47.05, B is 47.1, in C is 47.1 and in D is 47.4.
Also, we know that the median mass for Alia's Sample is greater than Tasneem.
Thus, the correct plot is D.
