Average Tim correctly answers 12 out of 18 questions in a trivia game assuming the situation is proportional how many more questions is he likely to get correct if there are 30 questions and all
Answer:
Step-by-step explanation:
12/18= 2/3, that’s the ratio of how many questions he gets right compared to total questions
So if there are 30 questions total, he will get 20 right (30 x 2/3)
If you’re taking into consideration that he already answered 18 questions, he will get 8 more correct

If my heart beats 2790 times every three quarters of an hour, what is your heart rate per minute?
Your heart rate is the number of times each minute that your heart beats, which is normally between 60 and 100 times per minute for adults. Your pulse is a way you can feel each time your heart beats. Measuring your heart rate helps you monitor your own health and know if you’re exercising at the right level to get the most benefits to your health.
Your pulse is your heart rate, or the number of times your heart beats in one minute. Pulse rates vary from person to person. Your pulse is lower when you are at rest and increases when you exercise (more oxygen-rich blood is needed by the body when you exercise). Knowing how to take your pulse can help you evaluate your exercise program.
352,345,338,... Find the 43rd term
Step-by-step explanation:
it seems we are dealing with subtraction, as the differences between the 1st and second, and between the 2nd and 3rd numbers are equal : -7
so, we can assume that the sequence is created by always subtracting 7.
a1 = 352
a2 = a1 - 7 = 352 - 7 = 345
a3 = a2 - 7 = a1 - 7 - 7 = 352 - 7 - 7 = 338
an = an-1 - 7 = a1 - 7(n-1) = 352 - 7(n-1)
a43 = 352 - 7(43-1) = 352 - 7×42 = 352 - 294 = 58

The length of a rectangular frame is represented by the expression 2x + 10, and the width of the rectangular frame is represented by the expression 2x + 6. Write an equation to solve for the width of a rectangular frame that has a total area of 140 square Inches.
A: 4x^2+32x-80=0
B: 4x^2+32x+60=0
C: 2x^2+32x-80=0
D: x^2+16x+60=0
Answer:
A
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = length × width
= (2x + 10)(2x + 6) ← expand using FOIL and equate to 140
= 4x² + 12x + 20x + 60 = 140
= 4x² + 32x + 60 = 140 ( subtract 140 from both sides )
4x² + 32x - 80 = 0
Answer:
A: 4x² + 32x - 80 = 0
Step-by-step explanation:
Length = 2x + 10 inWidth = 2x + 6 inArea = 140 in²Formula
Area (rectangle) = Length x WidthSolving :
140 = (2x + 10)(2x + 6)2x(2x) + 10(2x) + 2x(6) + 10(6) = 1404x² + 20x + 12x + 60 = 1404x² + 32x - 80 = 0The correct option is AWhat is the distance between (-5,8) and( 6,8)

F(5)=12 for a geometric sequence that is defined recursively by the formula f(n)=0. 3*f(n-1), where n is an integer and n>0. Find f(7) Round your answer to the nearest hundredth
Answer:
f(7) = 1.08
Step-by-step explanation:
The recursive formula can be used with the given value to find the desired value.
__
Given:
f(n) = 0.3×f(n-1) . . . . . where f(5) = 12
The next term in the sequence is ...
f(6) = 0.3×f(5) = 0.3(12) = 3.6
f(7) = 0.3×f(6) = 0.3(3.6) = 1.08

A boating company has the following notice at the gate:
"Children under the age of 13 are not allowed to operate a boat".
Part A- Write an inequality to show the age of children who are allowed to operate a boat.
Part B- Describe in words how you can show the solution to this inequality of a number line.
Answer:
Part A:
x > 13
Part B:
How to show this inequality on a number line is a closed circle on 13, going left of 13.
Step-by-step explanation:
Part A:
x represents the age of children who are allowed to operate the boat.
Our inequality is < because if you are of the age of 13 you are allowed to operate the boat,
the inequality x > 13 reads x (the age of children) is greater than or equal to 13
Part B:
How to describe inequalities on a number line;
Closed circle: less than or equal to - or - greater than or equal to ( < , > )
Open circle: less than - or - greater than ( < , > )
To the right of the number on the number line: greater than
To the left of the number on the number line: less than
Answer:
Part A
Let x = age of child (in years)
Given:
"Children under the age of 13 are not allowed to operate a boat"
Therefore, children should be 13 or older:
⇒ x ≥ 13
Part B
Place a closed circle at 13.
Shade to the right of the closed circle.

Answer:
[tex]3\frac{1}{3}[/tex] or [tex]\frac{10}{3}[/tex]
Step-by-step explanation:
We could use the combined rate equation to find the combined rate of work.
Combined rate of work formula: [tex]\frac{1}{t_{b}} = \frac{1}{t_{1} } + \frac{1}{t_{2} }[/tex], where [tex]t_{1}[/tex] is the individual time for object A, [tex]t_{2}[/tex] the individual time for object B and [tex]t_{b}[/tex] is the time for A and B together.
The time it takes Irina to paint the room alone, [tex]t_{1}[/tex] = 5 hours
The time it takes Paulo to paint the room, [tex]t_{2}[/tex] = 10 hours
1) Substitute object A (Irina) and B (Paulo) into the formula given above, and change [tex]t_{b}[/tex] into an [tex]x[/tex].
[tex]\frac{1}{{x}} = \frac{1}{5 } + \frac{1}{10 }[/tex]
2) Add the fractions.
[tex]\frac{1}{x} = \frac{3}{10}[/tex]
3) Solve for the [tex]x[/tex].
[tex]x(3) = 1(10)\\3x = 10\\x = \frac{10}{3} \\[/tex]
4) Change them into a mixed fraction.
[tex]3\frac{1}{3}[/tex]
Note: [tex]\frac{10}{3}[/tex] or [tex]3\frac{1}{3}[/tex] are both correct. Write the answer according to the question. In this case, there is no specific rule, so I choose [tex]3\frac{1}{3}[/tex].

Answer:
Q' (2,4)
R' (3,1)
S' (5,3)
Step-by-step explanation:
When reflected across x-axis, the x-values stay the same but y-values change signs. Because you count how many points till the reflection line then same amount you have to go to the other side. But since it is saying x-axis, the reflection line is on x=0 so you just change the sign.
Answer:
Q=(2,4)
R=(3,1)
S=(5,3)
Step-by-step explanation:
The x value stays the same when reflecting in the x axis
And the y value would be an equal distance from the y-axis for all coordinates so you would make -4 into 4 ecause they are both 4 away from the y-axis line.

If f(x) = |x| 9 and g(x) = –6, which describes the range of (f g)(x)?
The range of the functions f(x) = |x| 9 and g(x) = –6 then (f+g)(x) will be equal to (f+g)(x)[tex]\geq[/tex]3 for all the values of x.
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
It is given that
[tex]f(x)=|x|+9[/tex]
[tex]g(x)=-6[/tex]
So now
[tex](f+g)(x)=|x|+9-6=|x|+5[/tex]
So from the above equation, we can see that (f+g)(x) describes the range (f+g)(x)[tex]\geq[/tex]3
