Multiplication/Division
Addition/Subtraction
30/(5+7)
parenthesis first so
5+7 = 12
30/12
then division
30/12= 2 6/12
6/12 can be simplified by 6 so
6/6 = 1 and 12/6 = 2
So your answer would be 2 1/2
The quotient of 30 and the sum of 5 and 7 is 2.5

You have a bag of gummy worms. 12 are green, 3 are blue, 6 are red, and 2 are orange. What is the probability that you will reach into the bag and pull a red worm, eat it, and then pull a green worm?
The probability that you will reach into the bag and pull a red worm, eat it, and then pull a green worm:
What is probability?Probability is a mathematical term, which can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. The possibility that an event will occur is measured by probability.
Probability of Event = Favorable Outcomes/Total Outcomes = X/n
The probability of pulling a red worm from the bag is 6/(12+3+6+2) = 6/23.
After eating the red worm, there are 11 green worms left in the bag, so the probability of pulling a green worm is 12/(12+3+2) = 12/17.
To find the probability of both events occurring (pulling a red worm and then a green worm), we need to multiply their probabilities:
P(red and green) = P(red) × P(green)
P(red and green) = (6/23) × (12/17)
P(red and green) = 72/391
Therefore, the probability of reaching into the bag and pulling a red worm, eating it, and then pulling a green worm is 72/391.

What fact will help you to find the measure of angles B and C in the diagram shown?
A) An equilateral triangle has 3 congruent angles.
B)
The height of an isosceles triangle bisects the base.
C) The base angles of an isosceles triangle are congruent.
D)
The midsegment of an isosceles triangle is parallel to the base
Answer:
The Answer is C
Step-by-step explanation:
Look at B and C you can see that they have a line on each angle. Also, know that isosceles have two congruent sides. So when looking at this triangle we can infer that C is our best bet.

A trampoline was originally priced at $100 but went on sale for 60% off. If Emmett bought the trampoline and paid 5% sales tax, how much did he pay in total? $
Answer: $42
Step-by-step explanation:
Since the trampoline was originally priced at $100 but went on sale for 60%, the price paid will be:
= $100 - (60% × $100)
= $100 - (0.6 × $100)
= $100 - $60
= $40
Emmett bought the trampoline and then paid 5% sales tax, the total amount paid will be:
= $40 + (5% × $40)
= $40 + (0.05 × $40)
= $40 + $2.
= $42
She paid $42 in total.

The point (-3, 2) lines on a circle whose equation is (x + 3)2 + ( + 1)2 = r2. Which of
the following must be the radius of the circle?
Answer:
3 units
Step-by-step explanation:
Equation of the circle is:
[tex] (x+3)^2 +(y+1)^2=r^2 [/tex]
[tex] \therefore [x-(-3)] ^2 +[(y-(-1)] ^2=r^2 [/tex]
Equating it with
[tex] (x-h)^2 +(y-k)^2=r^2 [/tex]
We find: h = - 3 & k = - 1
Center of the circle (C) = (-3, - 1)
Since, the point (-3, 2) lies on the circle, therefore radius of the circle wii be equal to the distance between the center of the circle (-3, - 1) and the point (-3, 2) which is on the circle.
Therefore,
[tex] r = \sqrt{[-3-(-3)]^2 +[2-(-1)]^2} [/tex]
[tex] r = \sqrt{[-3+3]^2 +[2+1]^2} [/tex]
[tex] r = \sqrt{[0]^2 +[3]^2} [/tex]
[tex] r = \sqrt{0 +9} [/tex]
[tex] r = \sqrt{9} [/tex]
[tex] r = 3\: units [/tex]

Answer:
a = 30°
b = 11°
Step-by-step explanation:
JK = 360 - 110 - 130 - 54 = 66°
Inscribed angles = 1/2 their arc
∠K = 1/2(130 + 54) = 92°
∠J = 1/2(110 + 130) = 120°
∠M = 1/2(66 + 110) = 88°
8b = 88°
b = 11°
∠L = 1/2(54 + 66) = 60°
2a = 60°
a = 30°

Your pay rate is $20 per hour and you have a weekly pay period. You have worked overtime and accumulated 50 hours for the week. You get paid time and a half for overtime hours. Calculate your gross pay. *
Answer:
$1200 gross pay
Step-by-step explanation:
if you worked 40 hours normally and had 10 hours over time, that equation for the gross pay would be X = 20(40) + 30(10)
X = 20(40) + 30(10)
X = 800 + 300
X = 1200
