Answer:
a) There are 25 pencils of other colour in the bag.
b) P(Blue) = 3/7
Step-by-step explanation:
A bag contains 70 pencils out of which 15 are green and 30 are blue.
a) How many pencils of other colour are in the bag?
This is calculated as:
70 - (15 + 30)
= 70 - 45
= 25 pencils
Hence, there are 25 pencils of other colour in the bag.
b) A pencil is selected from a bag at random .What is the probability that it is blue?
P(Blue) = Number of Blue pencils/Total number of Pencils
P(Blue) = 30/70
P(Blue) = 3/7

Answer:
228 I believe
Step-by-step explanation:
Input the values first
3[tex](7)^{2}[/tex] + [tex]9^{2}[/tex]
PEMDAS it so exponents first
Even though the 7 is in () it's being multiplied by 3 is exponent would still come first
3(49) + 81
147 + 81 = 228
Answer:
228
Step-by-step explanation:Take 7 and multiply it by itself. you get 49. times 49 by 3 you get 147. Take 9 and multiply it by itself. You get 81. 147 plus 81 = 228

Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:
Step-by-step explanation: I choose d because if you notice there are only 33 marbles in Bag F and Bag F-number of marbles is equal to 1/3 marbles = 11/33 marbles and Bag G contains only 11 marbles which are how many marbles there are in all bags.
Answer:
The probability of randomly selecting a blue marble from bag F is 1/3
Step-by-step explanation:
Let's logically work this out:
Bag G has 33 marbles.
Bag F has 11 marbles.
Each bag is mentioned to have 11 blue marbles, so that means there is a 1/3 chance of picking a blue marble from bag F and a 1/1 (100%) chance of picking a blue marble from bag G.
A is incorrect because the chance of picking a marble from bag G (about 33%) is less than bag F (100%).
B is incorrect because the probability is 1/3, not 1/1. If it said bag F, it would be correct, however it is not so.
C is incorrect because, as mentioned before, 33% is not larger than 100%. It specifically says bag F has a greater chance, so this isn't correct.
D IS correct not only because it's the last one left, but because 11/33 (blue marbles to all marbles in the bag) is equal to 1/3 when simplified.

Answer:
x < 16
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
−3x+21>−27
Step 2: Subtract 21 from both sides.
−3x+21−21>−27−21
−3x>−48
Step 3: Divide both sides by -3.
−3x−3>−48−3
x<16
Answer:
x<16
Step-by-step explanation:
Isolate (x-7) by dividing -3 to the other side. Remember that the direction of the inequality will change. X-7<9, add 7 so x<16.

I have to take care of my sister's cat while she is on vacation. The cat is a very picky eater and will only eat a certain cat food, available at two stores.
Gristede's sells 12 cans for $18
PetSmart sells 20 cans for $26
Which store is offering the best deal on cat food?
Make sure to explain how you were able to determine which store offers the best deal on the cat food.
What us the equivalent ratio for 4:3
Answer:
PetSmart is offering the best deal
Step-by-step explanation
For Gristede's we get 18 and divide it by 12 which would give us $1.50 per can
For PetSmart we get 26 and divide it by 20 which would give us $1.30 per can
find The value of x, y and z
Answer:
x = 18 ; y = 10 ; z = 102°
Step-by-step explanation:
The triangle in the pic is an isosceles triangle.
As it is an isosceles triangle , it's two sides will be equal .
[tex] = > 3x - 42 = 12[/tex]
[tex] = > 3x = 42 + 12 = 54[/tex]
[tex] = > x = \frac{54}{3} = 18[/tex]
Also, both the base angles will be equal.
[tex]4y - 1 = 39[/tex]
[tex] = > 4y = 39 + 1 = 40[/tex]
[tex] = > y = \frac{40}{4} = 10[/tex]
According to angle sum property of a triangle , sum of measure of all the angles of a triangle is equal to 180°. So,
[tex]z + 39 + 39 = 180[/tex]
[tex] = > z + 78 = 180[/tex]
[tex] = > z = 180 - 78 = 102[/tex]

Which graph represents the equation below?
y= 3(x – 3)^2 + 3
Answer:
Option 3
I hope this helps!
The graph represents the equation y = 3x² -18x + 30 is attached below, so option 3 is correct.
What is graph?A graph is a structure made up of a collection of things, where some object pairs are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.
Given:
y = 3(x – 3)² + 3
y = 3(x² + 9 - 6x) + 3
y = 3x² + 27 - 18x + 3
y = 3x² -18x + 30
This is a quadratic equation, so make a table of values of x and y,
put the values of x and find y, and then mark on the graph, and at last join all the dots.
The graph is attached below.

If person A pushes a box with 30 N of force to the right and person B pushes a box with 30 N of force to the left, what is the net force
Answer:
balanced
Step-by-step explanation:
The net force is zero.
What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
A person A pushes a box with 30 N of force to the right and person B pushes a box with 30 N of force to the left.
Now,
Since, The person A pushes a box with 30 N of force to the right.
So, Force = 30 N
And, The person B pushes a box with 30 N of force to the left.
So, Force = - 30 N
Thus, The net force = 30 N + (- 30) N
= 30 - 30
= 0
Therefore, The net force is zero.
