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

Hope this helps!

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.

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

Answer:

{(2, 9), (5, 9), (1, -6), (-5, 5), (2,9), (5,9), (1,−6), (−5,5)}

Step-by-step explanation:

recall that for a function to be valid, every input must give one and only 1 output. (i.e every x-ordinate must have only one unique corresponding y-ordinate)

I have highlighted in bold and underlined the entries for each of the other choices where an x-value gives more than one possible y-value, hence these are not functions. only the first option satisfies this condition:

{(2, 9), (5, 9), (1, -6), (-5, 5), (2,9), (5,9), (1,−6), (−5,5)} Every x-value has a unique y-value, so it is possible that this is a function.

{(6, 6), (6, 8), (-8, -7), (-3, -8), (6,6),(6,8),(−8,−7),(−3,−8)}  (not a function)

{(1, 8), (9, -3), (7, -4), (7, -6), (1,8),(9,−3),(7,−4),(7,−6)} (not a function)

{(-5, -1), (-3, -7), (-5, 3), (-7, -4), (−5,−1),(−3,−7),(−5,3),(−7,−4)} (not a function)

Answer:

360

Step-by-step explanation:

So, here's what we know...

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!

Step-by-step explanation:ok:)

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

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]

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.

Answer:

Step-by-step explanation:

If you substitute 0 to x the equation will not be right.

2*0 = 0 + 5

0 ≠ 5

0 is not equal to right. So 0 is not a solution for the equation.

The solution is actually 5. X=5

Answer:

:3))

Step-by-step explanation:

2x = x + 5                         original equation

2(0) = 0 + 5                      plug in 0 ("solution") for x

0 = 0 + 5                          simplify 2(0)

0 = 5 (not true)                 simplify 0 + 5

Because the final answer to the equation wasn't true when using the input value of 0 for x, we know that 0 is not a solution to this equation.

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

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)

Answer:

1. 768 square yards

2. 384 square yards

Step-by-step explanation:

1. 16 x 16 = 256

  256 x 3 = 768 square yards

2. 16 x 16 = 256

   256/2 = 128

   128 x 3 = 384 square yards

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
