Mrs. Roslin has 32 students in her class. Of these students, 14 are girls. She chooses one boy and one girl at random to help pass out papers. Determine the total number of outcomes.
(Basically how many different outcomes can be made... no explanation needed.)
Answers
Answer:
2 outcomes
Step-by-step explanation
The Roslin has 32 students in her class, of these students, 14 are girlsl number of outcomes are 252.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The total number of outcomes can be found by multiplying the number of options for choosing a boy by the number of options for choosing a girl:
Number of outcomes = number of options for choosing a boy x number of options for choosing a girl
Since Mrs. Roslin has 32 students in her class, there are 32 - 14 = 18 boys in her class.
So the number of options for choosing a boy is 18, and the number of options for choosing a girl is 14.
Therefore, the total number of outcomes is:
18 x 14 = 252
Hence, the total number of outcomes is 252.

What is the image point of (-5,3) after a translation left 3 units and down 1 unit?
Answers
Answer:
(- 8, 2 )
Step-by-step explanation:
A shift of 3 left means subtract 3 from the x- coordinate
A shift of 1 down means subtract 1 from the y- coordinate
Translation rule is
(x, y ) → (x - 3, y - 1 ), thus
(- 5, 3 ) → (- 5 - 3, 3 - 1 ) → (- 8, 2 )
Circle A has a diameter of approximately 20 inches and an area of 314 in2 (approximately 300 in2) Circle B has a diameter of approximately 60 inches and an area of 2826 in2 (approximately 2700 in2) Circle C has a diameter of approximately 40 inches. Find the area of Circle C and explain or show your reasoning.
Answers
Answer:
1256.8in^2Step-by-step explanation:
Step one:
Given data
Circle A
diamteter= 20 in
Area= 314 in^2 approx. 300in^2
Circle B
diamteter= 60 in
Area= 2826in^2 approx. 2700in^2
Step two:
Circle C
diamteter= 40 in
radius= 20 in
The expression for A is given as
A=πr^2
A=3.142*20^2
A=3.142*400
A=1256.8
The area of circle C is 1256.8in^2
what is the equation of a line in slope intercept form that is perpendicular to y=2x+2 and passes through the point (8,-4)
Answers
Answer:
The equation of the line that is perpendicular to y = 2x + 2 is
y = -1/2x
Step-by-step explanation:
The original equation is y = 2x + 2; it's slope is 2
Any line perpendicular to this equation would have to have a slope that is the negative reciprocal of the original slope.
Example:
y = 2x + 2 so,
the perpendicular line's slope must be -1/2
Write a new equation with the new slope:
y = -1/2x + b
We know that this line passes through (8, -4)
Plug these coordinates in the equation to find b, the y-intercept
-4 = -1/2 (8) + b
-4 = -4 + b
0 = b
b = 0
We do not have to write y = -1/2x + 0
So, our final answer is "y = -1/2x is perpendicular to y = 2x+2"
A ladder is leaning against a tall wall with the foot of the ladder placed at 7 feet from the base of the wall and the angle of elevation is 73' 30' 40"
Answers
Complete question is;
A 21 ft ladder is leaning against a tall wall with the foot of the ladder placed at 7 feet from the base of the wall and the angle of elevation is?
Answer:
θ = 70.5°
Step-by-step explanation:
The angle of elevation simply means the angle that the ladder makes with the ground. Let's call this angle θ.
I've attached a diagram showing the triangle made by this ladder and the wall.
From the attached diagram, we can see the triangle formed by the ladder and the wall.
We can find the angle of elevation θ from trigonometric ratios.
Thus;
7/21 = cos θ
cos θ = 0.3333
θ = cos^(-1) 0.3333
θ = 70.5°

Answer:
W = 40
L = 60
Step-by-step explanation:
L = 20 + W
L*W = 2400
(20 + W)*W = 2400
W^2 + 20*W - 2400 = 0
(W + 60)*(W - 40) = 0
W = 40 (yards)
L = 20 + W
= 20 + 40 = 60
W = 40

Bamboo Plant A is 1.2 meters tall and growing at a rate of 0.45 meter per day. Bamboo Plant B is 0.85 meter tall and growing 0.5 meter per day. After how many days will Plant B be taller than Plant A?
Answers
Answer:
7 days
Step-by-step explanation:
Bamboo plant A = 1.2 + 0.45d
Bamboo plant B = 0.85 + 0.5d
Where,
d = number of days
Equate the two growth
Bamboo plant A = Bamboo plant B
1.2 + 0.45d = 0.85 + 0.5d
Collect like terms
1.2 - 0.85 = 0.5d - 0.45d
0.35 = 0.05d
Divide both sides by 0.05
d = 0.35 / 0.05
d = 7 days
Plant B be taller than Plant A after 7 days

For me, typically I dont read the question properly and do the math wrong. Other moments I cant even figure out what exactly the question is even asking.
Step-by-step explanation:
You can try to read the word problem once first (no need to be really through just need to get an idea of what's really happening), and then read again, now a little more through, where you need to understand what the question wants of you. Once you understood the question, relate it to the topic you have learnt and see if there's any formula in this topic that you have been taught. If there is, keep all of these formulas in mind. If there isn't then it's good just search for all the numbers given in the question and form and equation in it or just solve. If there may be formulas involved, try relate the question/info given to the formulas you have in your head and yeah
