If I’m tiling a floor of a 10’ x 10’ room and find that 100 tiles will be needed how many tiles will be needed to tile a floor of 20’ x 20’ room
Answer:
400 Tiles
Step-by-step explanation:
20 x 20 = 400
(Length x Width)
Answer:
400
Step-by-step explanation:
Enough that you will need a large piggy bank to take money out of.\
There are 4 squares of equal size that will fit the floor of a 20 by 20 foot room.
Therefore you will need 4 * 100 = 400 tiles.
You could do it by noting that the floor has 20 by 20 tiles which is 20^2 which is 400.

How do you find p(a and b) ?
Answer:
Formula for the probability of A and B (independent events): p(A and B) = p(A) * p(B). If the probability of one event doesn't affect the other, you have an independent event. All you do is multiply the probability of one by the probability of another.

The sum of a number and twice another number is 17. The sum of twice the first number and the second number is 4. What are the two numbers?
a) define the variables
b) write a system of equations
c) solve by elimination
Step-by-step explanation:
Given that,
a + 2b = 17
Also,
2a + b = 4
By adding the above expressions we get,
a + 2b + 2a + b = 17 + 4
3a + 3b = 21.
3 (a + b) = 21
a + b = 21/3
a + b = 7 Let us take 'b' = 10
a + 10 = 7
a = 7 - 10
a = -3
Now let's check by verifying by putting a = -3 and b = 10 in the previous expressions
a + 2b = 17
-3 + (2 × 10) = 17
-3 + 20 = 17
17 = 17
2a + b = 4
(2 × -3) + 10 = 4
-6 + 10 = 4
4 = 4
Therefore, a = -3 and b = 10 [(-3,10)] is the solution.

What's the diameter of 76cm circle circumference
Answer:
The circumference of a circle is C = 2πr^2 (2nd power) Radius (r) is the distance from the center of the circle to the outside of it. To find radius divide the diameter (d) by 2. The diameter (d) of a circle is the radius (r) multiplied by 2. To find the diameter (d) you need to do C ÷ π.
For example):
Finding diameter - 76/3.14 = 24.19 (d)
Finding radius - 24.19/2 = 12.095 (r)

Andres has 3,240 cookies and is putting them in boxes and wants 9 cookies in each.
To solve this, the easiest way is to divide 3,240/9. Since Andres is splitting putting 9 cookies in a box. The equation to solve this would be...
3,240 cookies ÷ 9 cookies per box = x boxes
Now, let's do the math!
3,240 ÷ 9 = 360
So, Andres used 360 boxes!

For her phone service, Kaitlin pays a monthly fee of $10, and she pays an additional $0.07 per minute of use. The least she has been charged in a month is $105.27. What are the possible numbers of minutes she has used her phone in a month? Use m for the number of minutes, and solve your inequality for m.
The equation of this problem is:
0.07m + 10 ≥ 105.27
Subtract 10 from both sides:
0.07m ≥ 95.27
Divide 0.07 on both sides:
m ≥ 1,361
Therefore, the number of minutes that Kaitlyn acquires each month is greater than or equal to 1,361 minutes.
Hope this helps!!

The possible number of minutes Kaitlin has used her phone in a month is 1361 minutes or more.
Let's set up an inequality to represent Kaitlin's monthly charges. We know that the total cost, C, for the month is the sum of the monthly fee ($10) and the additional charge based on the number of minutes used ($0.07 per minute, which can be written as 0.07m, where m represents the number of minutes used).
So, the inequality can be written as: C = 10 + 0.07m
Now, we are given that the least amount she has been charged in a month is $105.27. Therefore, we can write the inequality:
C ≥ 105.27
Substitute the expression for C from the first inequality: 10 + 0.07m ≥ 105.27
Now, solve for m:
Subtract 10 from both sides of the inequality:
0.07m ≥ 105.27 - 10
0.07m ≥ 95.27
Finally, divide both sides of the inequality by 0.07:
m ≥ 95.27 / 0.07
m ≥ 1361

How many roots do the functions have in common?
f(x)=2x^2-4x-16
Please Help??
Answer:
Step-by-step explanation:
Given the function f(x)=2x^2-4x-16
To know the amount of roots that the function have in common, we need to first factorize the expression as shown;
f(x)=2x^2-4x-16
f(x)=2x^2-8x-16
Let f(x) = 0
0 =2x^2-4x-16
2x^2-4x-16 = 0
Divide through by 2;
x^2-2x-8 = 0
x^2 - 4x + 2x - 8 = 0
x(x-4)+2(x-4) = 0
(x+2)(x-4) = 0
x = -2 and 4
Hence the roots of the function are -2 and 4. They did not have any common roots

-----------------------------------------
2. If OQ and RT are parallel lines which statement is true?
A) RSP is congruent to RSU
B) RSP is congruent to PST
C) RSP is congruent to TSU
D) RSP is congruent to OPS (my answer)
Answer:
1. A) OPS is congruent to RSU
2. C) RSP is congruent to TSU
Step-by-step explanation:
1. Since OQ and RT are parallel lines that are cut across by the transversal line, NU, therefore, angle OPS and angle RSU are corresponding angles formed. Corresponding angles are congruent.
✅Therefore: A) OPS is congruent to RSU. OPTION A IS TRUE.
❌OPS and RSP are consecutive interior angles. They are not congruent. They are supplementary. So, option B is NOT TRUE.
❌OPS and OPN are linear pair angles. Linear pair angles are not congruent. They are supplementary. Therefore, OPTION B IS NOT TRUE.
OPS and TSU are also not congruent.
2. Angle RSP and angle RSU are vertical angles. Vertical angles are congruent. Therefore, the statement that IS TRUE is:
C) RSP is congruent to TSU

An object with initial temperature 120° F is submerged in large tank of water whose temperature is
70°F. Find a formula for F(t), the temperature of the object after t minutes, if the cooling constant is
k= 0.2
F(t)=
Answer:
[tex]F(t)=Ts+(T0-Ts)^{e-0.2t[/tex]
Step-by-step explanation:
Newton's law of cooling states
"that the temperature of a body changes at a rate proportional to the difference in temperature between the body and its surroundings"
Newton's Law of Cooling is given by the formula
[tex]F(t)=Ts+(T0-Ts)^{e-kt[/tex]
Where
F( t ) is the temperature of the object at a given time t
T s is the surrounding temperature
T 0 is the initial temperature of the object
k is the constant
Given k=0.2
Hence the expression is
[tex]F(t)=Ts+(T0-Ts)^{e-0.2t[/tex]
