Answer:

[tex]\%Percent = 30 \%[/tex]

Step-by-step explanation:

Given

[tex]Shaded = 6\ cubes[/tex]

[tex]Box = 5\ x\ 4[/tex]

Required

Determine the percentage of the shaded cubes

First, we calculate the number of boxes:

[tex]Box = 5\ x\ 4[/tex]

Express as multiplication

[tex]Box = 5\ *\ 4[/tex]

[tex]Box = 20[/tex]

This implies that there are 20 cubes in the box.

The percentage of the shaded cubes is:

[tex]\%Percent = \frac{Shaded}{Box} * 100\%[/tex]

[tex]\%Percent = \frac{6}{20} * 100\%[/tex]

[tex]\%Percent = \frac{6* 100}{20} \%[/tex]

[tex]\%Percent = \frac{600}{20} \%[/tex]

[tex]\%Percent = 30 \%[/tex]

30% were shaded

Answer:

x ≤ 13.2.

Step-by-step explanation:

6  ≥  x/2.2

Multiply both sides by 2.2:

6 * 2.2 ≥ x

x ≤ 13.2.

The solution to the inequality is [tex]x \leq 13.2[/tex], the correct symbol used in blank is  ≤.

To complete the solution to the inequality [tex]6 \geq \frac{x}{2.2}.[/tex]

Rearrange the inequality as follows:

[tex]\frac{x}{2.2} \le 6[/tex]

The solution to the inequality is:

[tex]x \leq 13.2[/tex]

Comparing the expression [tex]\frac{x}{2.2}[/tex] to 6, we can see that [tex]\frac{x}{2.2}[/tex] should be less than or equal to 6 in order for the inequality to hold true.

Therefore, the correct symbol to place in the blank is "≤" and solution is [tex]x \leq 13.2[/tex].

Answer:

p = 2 or p = -2

Step-by-step explanation:

Solve for p over the real numbers:

16 p^2 - 64 = 0

Hint: | Factor constant terms from the left hand side.

16 p^2 - 64 = 16 (p^2 - 4):

16 (p^2 - 4) = 0

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides by 16:

p^2 - 4 = 0

Hint: | Using the quadratic formula, solve for p.

p = (0 ± sqrt(0^2 - 4 (-4)))/2 = ( ± sqrt(16))/2 = ( ± 4)/2 = ± 2:

Step-by-step explanation:

Answer:

(6,-7)

Step-by-step explanation:

subtract them:

-8x - 5y = -13

-4x - 5y = 11

you get

-4x = -24

so x = 6

plug x into the second equation:

-24 - 5y = 11

-5y = 35

y = -7

so your solution is (6,-7).

Answer:

Your solution is (6, -7).

Step-by-step explanation:

Combining the equations is also known as substitution. This is done when you substitute one variable into another equation.

-8x - 5y = -13

-4x - 5y = 11

Let's change the second equation into one with one variable on each side.

-5y = 4x + 11

y = -4/5x - 11/5

Now, plug this into your first equation.

-8x - 5(-4/5x - 11/5) = -13

Distribute the -5 sign.

-8x + 4x + 11 = -13

Combine the like terms.

-4x + 11 = -13

-4x = -24

Isolate x by dividing both sides by -4.

x = -24/-4

x = 6

Now plug this back into either equation.

y = -4/5(6) - 11/5

Multiply.

y = -24/5 - 11/5

Subtract.

y = -35/5

Simplify.

y = -7

Your solution is (6, -7).

Check this by plugging in these values into the equation you have not checked yet.

-8(6) - 5(-7) = -13

-48 + 35 = -13

-13 = -13

Your solution is correct.

Step-by-step explanation:

Catherine bought apples and pears for the school picnic. If the total fruit is less than 100, then the correct equation for this will be y<100-x and y<x. Hence, option C is correct.

Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

As per the given data in the equation,

Catherine bought apple and pears.

The overall quantity is less than 100

Let the number of apples is x and,

The number of pears is y.

She bought more apples than pears,

y<x.

And y < 100-x.

Answer:

What figure?

Step-by-step explanation:

Answer:

The function have a constant ratio

No, it does not represent an exponential function.

Step-by-step explanation:

As given,

Ines has saved $5. She doubles the amount she saves each week.

⇒ In first week she saved = $5

   In second week she saved = 2×$5 = $10

   In third week she saved = 2×$10 = 20

  In fourth week she saved = 2×$20 = 40

and so on..

∴ we get the series

5, 10, 20, 40 ,.......

If the series is given as a, b, c, d, ..... , then

The common difference is defined as d = b-a = c-b

The common ration is defined as r = [tex]\frac{b}{a} = \frac{c}{b}[/tex]

Here, in the given question

The series is - 5, 10, 20, 40

This has no common difference , d =   10 - 5 (= 5 )≠ 20 - 10 (= 10)

As 5 ≠ 10

So the function does not define common difference .

Now,

This has common ratio , r =  [tex]\frac{10}{5} (=2) = \frac{20}{10}(=2)[/tex]

As 2 = 2

So, the function represent common ratio

Now,

The function does not represent an exponential function because it is increased by common ratio.

5 = 1/2x

x = 5/1/2

x = 10/1

Answer:

x=5 cm,y=12 cm

Step-by-step explanation:

We are given that

RQ=3 m

PQ=4 cm

RP=x cm

RS=13 cm

SP=y cm

We know that Pythagoras theorem

[tex](Hypotenuse)^3=(base)^2+(perpendicular\;side)^2[/tex]

In right triangle RQP

Using Pythagoras theorem

[tex]RP^2=RQ^2+PQ^2[/tex]

Substitute the values

[tex]x^2=3^2+4^2[/tex]

[tex]x^2=9+16[/tex]

[tex]x^2=25[/tex]

[tex]x=\sqrt{25}=5[/tex]cm

Now,

In triangle RPS

[tex]RS^2=RP^2+SP^2[/tex]

[tex](13)^2=5^2+y^2[/tex]

[tex]169=25+y^2[/tex]

[tex]169-25=y^2[/tex]

[tex]144=y^2[/tex]
