Answer:

Step-by-step explanation:

3,249

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!

Hope this Helps! :)

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

Answer:

A bat

Step-by-step explanation:

Answer:

The bat flies faster by 7 feet

Step-by-step explanation:

first, you need to find some common ground. 84 and 4 can both be divided by two 84/2=42 so now we know that:

-The bat flies 42 feet in two seconds

-The dove flies 35 feet in two seconds

So we know that the bad flies faster because the number is greater, but by how much?

To find this just subtract 35 from 42 to get 7.

So to summarize

The bat flies faster by 7 feet

Given:

Total number of marbles in the bag = 150

There are 21 blue marbles for every 4 white marbles.

To find:

The number of blue marbles in the bag.

Solution:

Since, there are 21 blue marbles for every 4 white marbles, therefore the ratio of blue marble to white marbles is 21:4.

Let the number of blue marbles be 21x and white marbles be 4x.

Total number of marbles in the bag = 150

[tex]21x+4x=150[/tex]

[tex]25x=150[/tex]

Divide both sides by 25.

[tex]x=\dfrac{150}{25}[/tex]

[tex]x=6[/tex]

Now,

[tex]\text{Blue marbles}=21x[/tex]

[tex]\text{Blue marbles}=21(6)[/tex]

[tex]\text{Blue marbles}=126[/tex]

Therefore, the number of blue marbles is 126.

Since we are looking for a polynomial with RATIONAL coefficients, then we know that if [tex]3-\sqrt{2}[/tex]  is a root, then its conjugate  [tex]3+\sqrt{2}[/tex] must also be a root

Therefore, we build the polynomial using binomial factors with the given roots as shown below:

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

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]

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:

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:

Step-by-step explanation:

Given the expression of the speed satisfying the equation |S-60|≤17.5

The inequality expression will return both a negative and positive value.

For the positive value of the function;

S-60 ≤17.5

S ≤17.5+60

S  ≤ 77.5

For the negative value of the function;

-(S-60) ≤17.5

-S+60 ≤17.5

-S  ≤17.5 -60

-S  ≤ -42.5

multiply through by -1

S≥42.5

Hence the minimum speed limit is S≥42.5 while the maximum is S  ≤ 77.5

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:

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:

f and g share the same root(s).

Step-by-step explanation:

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:

501.5

Step-by-step explanation:

Fill it in.

Answer: 2.7x (27 + 4x) - 45y + 2 = 501.5

Step-by-step explanation:

Start with 2.7x (27 + 4x)

so 2.7(5) = 13.5

and then you change the number that multiplies with the others:

13.5 (27 + 4x)

Then multiply them:

364.5 + 54x

And then add them with the rest of your equation:

364.5 + 54x - 45y + 2

Now multiply the numbers that have the variables:

364.5 + 54x - 45y + 2

54(5) = 270  and -45(3) = -135

then add them to the equation again:

364.5 + 270 -135 + 2

And then add them or subtract them altogether (I added 364.5 and 270 first and I got: 634.5. And then I subtracted/added -135 + 2 second and I got: -133.

then do 634.5 - 133 and you should get 501.5.

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)
