We will see that there are 35 two-digit odd numbers larger than 20.
How many odd 2-digit positive integers greater than 20 are there?So in each range of 10 consecutive numbers, we have 5 odd ones.
For example, between 20 and 30 we have:
{21, 23, 25, 27, 29}
And from 20 to 100 (we count to 100 because we only care for 2-digit integers) there are 7 sets of 10s
(20 to 30), (30 to 40), (40 to 50), (50 to 60), (60 to 70), (70 to 80), (80 to 90), (90 to 100).
And we know that in each one of these 7 sets we have 5 odd numbers, so we can conclude that there are:
7*5 = 35 2-digit odd numbers larger than 20.

3x + 7 = y-5
trying to find y
Answer: Simplifying
3x + 7 = y + -5
Reorder the terms:
7 + 3x = y + -5
Reorder the terms:
7 + 3x = -5 + y
Solving
7 + 3x = -5 + y
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + 3x = -5 + -7 + y
Combine like terms: 7 + -7 = 0
0 + 3x = -5 + -7 + y
3x = -5 + -7 + y
Combine like terms: -5 + -7 = -12
3x = -12 + y
Divide each side by '3'.
x = -4 + 0.3333333333y
Simplifying
x = -4 + 0.3333333333y

Your friends shuffle the cards and then deal them. Select probability of getting a red card. Select probability of getting a spade card.
Answer:
1/2 ; 1/4
Step-by-step explanation:
Number of cards in a deck = 52
Number of red cards = 26
Number of spades = 13
Probability of event A :
P(A) = required outcome / Total possible outcomes
P( red card) = number of red cards / total cards in deck
P(red card) = 26 / 52 = 1/2
P(spade) = number of spades / total cards in deck
P(red card) = 13 / 52 = 1 / 4
What is the volume of the triangular prism
Hight 10in
Base 14 in
Length 6
Answer:
[tex]V=336\ in^3[/tex]
Step-by-step explanation:
Triangular Prism
Given a triangular prism of base area A and height H, its volume is obtained with the formula:
V = AH
The area of the base is calculated as follows:
[tex]A = \frac{WL}{2}[/tex]
Where W is the width and L is the length. Both dimensions must be perpendicular.
The triangle of the base has a hypotenuse equal to 10 in and the width is 6 in, the length is calculated by:
[tex]L=\sqrt{10^2-6^2}[/tex]
[tex]L=\sqrt{100-36}=\sqrt{64}[/tex]
L = 8 in
The area is:
[tex]A = \frac{6*8}{2}[/tex]
[tex]A = 24\ in^2[/tex]
Finally, the volume is:
[tex]V = 24\ in^2*14\ in[/tex]
[tex]\boxed{V=336\ in^3}[/tex]

I thought of a number, subtracted it from 6 1/4 , multiplied the difference by 1 2/3 and then by 2 4/5 . The result was the same as the result of division of 146 by 5 3/14 . What was my number?
Answer:
The number was 1/4
Step-by-step explanation:
Let the
number be x
from the question, we have
6 1/4 - x
multiplied difference;
(6 1/4 - x) 1 2/3
The
next multiplication will give;
1 2/3 * 2 4/5
= 5/3 * 14/5 = 14/3
So we have;
(6 1/4 - x) 14/3
Result is same as:
146 divided by 5 3/14
= 146 * 14/73 = 28
Thus;
(61/4 - x) * 14/3 = 28
(25/4 - x) * 1/3 = 28/14
(25/4 - x) * 1/3 = 2
(25-4x)/4 = 6
25-4x = 6(4)
25-4x = 24
25-24 = 4x
4x = 1
x = 1/4

Answer:
b=3, y=6
Step-by-step explanation:
Label the 2 equations:
2b +6y= 42 -----(1)
2b +4y= 30 -----(2)
(1) -(2):
(2b +6y) -(2b +4y)= 42 -30
2b +6y -2b -4y= 12
2y= 12
y= 12 ÷2 (÷2 on both sides)
y= 6
Susbt. y=6 into (2):
2b +4(6)= 30
2b +24=30
2b= 30 -24 (-24 on both sides)
2b= 6
b= 6 ÷2
b= 3
Answer:
y = 6, b = 3
Step-by-step explanation:
Since both equations have 2b in them, subtracting them gets you a quick result because the 2b-2b cancels out!
2b + 6y = 42
2b + 4y = 30
------------------ -
2y = 12
y = 6
Then 2b = 42 - 36 = 6, so b = 6/2 = 3

What is 1 + 3 (x - 5)
Answer:
1 + 3 (x - 5) = 3x - 14
Step-by-step explanation:
Given:
1 + 3 (x - 5)
Open parenthesis
= 1 + {(3 * x) - (3 * 5)}
= 1 + (3x - 15)
= 1 + 3x - 15
= 3x - 14
1 + 3 (x - 5) = 3x - 14
A school chorus has 90 sixth-grade students and 75 seventh-grade students. The music director wants to make groups of performers, with the same combination of sixth- and seventh-grade students in each group. She wants to form as many groups as possible.
Answer:
The music director could make 15 groups of performers with 6 6th grade students and 5 7th grade students in each group.
Step-by-step explanation:
Since in the question it is mentioned that
There is 90 6th grade students and 75 7th grade students
Now factor could be done in the following ways
90 = 2 × 45 = 2 × 3 × 15 = 2 × 3 × 3 × 5
75 = 3 × 25 = 3 × 5 × 5
Now the GCF of 90 and 75 is
= 3 × 5
= 15
So,
90 = 15 × 6
75 = 15 × 5
Hence, The music director could make 15 groups of performers with 6 6th grade students and 5 7th grade students in each group.
3x - y = 5
2x + 3y = 7

How do you simplify square roots.
Answer:
Simplifying a square root just means factoring out any perfect squares from the radicand, moving them to the left of the radical symbol, and leaving the other factor inside the radical symbol. If the number is a perfect square, then the radical sign will disappear once you write down its root.

This sign shows when a lift is safe to use.
Total mass of people must be 480 kg or less
Fred and some other people are in the lift and their total mass
is 565 kg to the nearest 5 kg.
Fred, who has a mass of 88 kg to the nearest kg, gets out of the lift.
Is the lift now safe to use?
You must show your working and clearly state 'Yes it is safe' or 'No it is not safe'
Answer:
Yes it is safe
Step-by-step explanation:
lower bound of fred's weight (88kg) = 87.5kg
upper bound of total mass (480kg) = 567.5 kg
567.5kg - 87.5kg = 480 kg
The total mass in the lift after Fred gets out is [tex]477[/tex] kg which is less than the safe limit of [tex]480[/tex] kg. So, the lift is safe to use.
Maximum mass in the lift [tex]= 480[/tex] kg.
Total mass of Fred and other people in the lift [tex]= 565[/tex] kg.
Mass of Fred, in nearest kg, [tex]= 88[/tex] kg.
Fred gets out of the lift. So, subtract the mass of Fred from the total mass in the lift.
Total mass of people in the lift [tex]= 565-88 = 477[/tex] kg, which is less than safe limit of mass in the lift.
So, the lift is safe to use now.

What is an equivalent expression for 4(2m + n)
Answer:
8m+4n
Step-by-step explanation:
4(2m+n)
you have to distribute 4 to 2m and n
so your answer will be
8m+4n
Hope this helped :))
Answer:
8m + 4n
Step-by-step explanation:
To find the answer, you should distribute the 4 on the outside of the parentheses to each of the terms inside the parentheses, which would get: 4(2m) + 4n.
Simplify 4(2m) by multiplying, which gets 8m.
The equation is then 8m + 4n, which cannot be added together because the variables are different.
