Answer:

One fruit kabob and one smoothie

Two fruits kabobs and two smoothies

Three fruit kabobs and one smoothie

One fruit kabob and two smoothies

Explanation:

In this situation, the basic combination John can afford is simply to buy one fruit kabob and one smoothie ( $1.75 + $ 2.50 = $4.25) because he wants at least one unit of each item. Additionally, it is possible to add more units of each item to create new combinations or possibles, just make sure they do not total more than 9 dollars, which is the money John has. Here are some of the possible combinations:

Two fruit kabobs and two smoothies

Fruit kabobs: $1.75 x 2 = $3.5

Smoothies: $ 2.50 x 2 = $5

Total: $8.5

Three fruit kabobs and one smoothie

Fruit kabobs: $1.75 x 3 = $5.25

Smoothie: $2.50

Total: $7.75

One fruit kabob and two smoothies

Fruit kabob: $1.75

Smoothies: $2.50 x 2 = $5

Total: $6.75

x=9

Step-by-step explanation:

Answer:

x = 9

Step-by-step explanation:

According to the Product of a Power Property, when you multiply the power with the same base, you just have to add the exponents.

Answer:

1 + i[tex]\sqrt{5}[/tex], 1 - i[tex]\sqrt{5}[/tex]

Step-by-step explanation:

A quadratic function is    f(x) = a[tex]x^{2}[/tex] + bx + c

Your function with the given values is   f(x) = 2[tex]x^{2}[/tex] - 4x + 12

To solve a quadratic function, you can use the quadratic formula  

(-b +/- [tex]\sqrt{b^{2} - 4ac}[/tex]) / 2a

Fill in with your given values.

(4 +/- [tex]\sqrt{(-4^{2} - 4 (2) (12)}[/tex] ) / 2(2)

Simplify

(4 +/- [tex]\sqrt{16 - 96}[/tex]) / 4

(4 +/- [tex]\sqrt{-80}[/tex] ) / 4

Because there is a negative number under the square root making it an imaginary number put an i by it.

(4 +/- i[tex]\sqrt{80}[/tex]) / 4

80 is divisible by 16, a perfect square. 80 / 16 = 5

(4 +/- 4i[tex]\sqrt{5}[/tex]) / 4

Divide by 4

1 +/- i[tex]\sqrt{5}[/tex]

Your teacher may want you to list your radical without the i and just as [tex]\sqrt{-5}[/tex], so keep that in mind.

Don't forget to list it both as addition and subtraction.

Consider the given number is [tex]\sqrt{30}[/tex] in question as well as in options.

Given:

[tex]\sqrt{30}[/tex] is considered as an irrational number.

To find:

The reason for given statement.

Solution:

We have,

[tex]\sqrt{30}=5.47722557505...[/tex]

When evaluated, [tex]\sqrt{30}[/tex] results in a nonterminating (infinite digits after decimal) and nonrepeating decimal, which  is considered an irrational number.

Therefore, the correct option is C.

Answer:

counting numbers is another name

Answer:

A. x+30

B. x+35

Step-by-step explanation:

A. Daniel

Since "Daniel is 30 cm taller than Katie" and "Katie's height is x cm", the expression will be x+30

B. Juli (sorry I can't type the full name due to Brainly system)

Since "Juli is 5 cm taller than Daniel" and Daniel is (x+30) cm, the expression will be (x+30)+5=x+35

Answer:

the time is the independent quantities and the dependent one is the mass of the turkey

Step-by-step explanation:

Answer:

m = 5

Step-by-step explanation:

-9 - m = -4 -2m

-m = -4 +9 - 2m

-m = 5 -2m

2m - m = 5

m = 5

Hi!

Your answer should be: 3/c, "c= (5)($7)"

Reason being:

A: it only has the number of tickets, so that wouldn't make sense.

B: It has both numbers, but, were not adding, because the tickets cost $7 EACH, so only adding them wouldn't give you the right answer.

C: They are multiplying 5x$7, which is correct because  each ticket is $7, and she is trying to buy 5, so 5x$7=c is correct.

D: like A, they only have one part of the problem, so it wouldn't make sense.

Hope this helps!

Yours truly,

Answer:

I did this in a test so the answer is the third one. i already knew the answer was the third one.

Step-by-step explanation:

Lets check all of em first.

c = 5

(c) cant equal five because (c) is the total cost for tickets and if she bought 5

and each of them is $7  it cant be 5 thes goes same for the other-  c = $7

Now for c = 5 + $7 Clearly you cant find out the total cost for 5 tickets using addition.

therefore, the right answer is c = (5) ($7)

Explanation= You basically do x=6 on the graph then you shade in the right side because that represents that x is GREATER THAN OR EQUAL to 6.

Answer: 2

Step-by-step explanation:

When you take the square of a number, you are taking it to the 2nd power

Answer:

squaring a number is raising that number to the power of 2

Step-by-step explanation:

for example:

Answer:

-102

Step-by-step explanation:

-38

-120

-158

+56

-102

Answer:

Step-by-step explanation:

Given the explicit rule function F(n) = 15n +10, in order to get the 52nd term of the sequence, we will have to substitute n = 52 into the rule given as shown;

f(52) = 15(52) + 10

f(52) = 780+10

f(52) = 790

Hence the 52nd term of the explicit rule is 790

Answer:

[tex]x=5/3\text{ or } x=1[/tex]

Step-by-step explanation:

We have the equation:

[tex]27x^6-152x^3+125=0[/tex]

We can solve this using u-substitution. Let's let u=x³. Therefore:

[tex]27(x^3)^2-152(x^3)+125=0[/tex]

Substitute all x³s for u:

[tex]27u^2-152u+125=0[/tex]

This is now in quadratic form. So, we can use the quadratic formula:

[tex]u=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

Our a is 27, b is -152, and c is 125. So:

[tex]u=\frac{-(-152)\pm \sqrt{(-152)^2-4(27)(125)}}{2(27)}[/tex]

Simplify:

[tex]u=\frac{152\pm\sqrt{9604}}{54}[/tex]

Simplify:

[tex]u=\frac{152\pm 98}{54}[/tex]

Reduce. Divide everything by 2:

[tex]u=\frac{76\pm49}{27}[/tex]

Split into two cases:

[tex]u=\frac{76+49}{27}\text{ or } u=\frac{76-49}{27}[/tex]

Solve for each case:

[tex]u=\frac{125}{27}\text{ or } u=\frac{27}{27}=1[/tex]

Substitute back x³ for our u:

[tex]x^3=\frac{125}{27}\text{ or } x^3=1[/tex]

Take the cube root of each equation:

[tex]x=\sqrt[3]{\frac{125}{27}}\text{ or } x=\sqrt[3]1[/tex]

Evaluate:

[tex]x=5/3\text{ or } x=1[/tex]

And that's our two solutions.

And we're done!
