What's the diameter of 76cm circle circumference
Answers
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)

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)
Answers
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
what is 8y – 3z + 2 + 10y + 5z – 2 simplified?
Answers
Answer:
18y + 2z
Step-by-step explanation:
So first things is first, arrange all terms with the same degree.
8y + 10y - 3z + 5z + 2 - 2
Next combine like terms for everything
8y + 10y = 18y cuz 8 + 10 is 18.
-3z + 5z = 2z cuz -3 + 5 = 2
2 - 2 = 0 cuz that's a rule in math.
So the final answer is 18y + 2z.
You don't have a whole number cuz it is 0. You can put it there if you want as well.
18y + 2z + 0

Answers
Answer:
17.5 tour guides are needed . In my idea.
Answer:
18
Step-by-step explanation:
If you add all of the students then divide by 8 you get 17.5. However, you can't have .5 of a tour guide, so you round up to 18.
28+35+22+33+22=140
140/8=17.5
17.5 ≈ 18 tour guides

How many roots do the functions have in common?
f(x)=2x^2-4x-16
Please Help??
Answers
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

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
Answers
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.

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)=
Answers
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]
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.
Answers
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!!
Kay
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

3,240 cookies ÷ 9 cookies per box = x boxes
Now, let's do the math!
