Is 30/5 an integer number

Answer:

C - AC equals AD times AB over AE

Step-by-step explanation:

If Hiro is creating a larger scaled replica of a triangular canvas, then Hiro will get two similar triangles ABE (the small one) and ACD (the large one). Similar triangles have proportional corresponding sides, so

[tex]\dfrac{AC}{AB}=\dfrac{AD}{AE}[/tex]

From this proportion:

[tex]AC=\dfrac{AD\cdot AB}{AE}[/tex]

So, option C (AC equals AD times AB over AE) is correct option

Answer:

Yes there is GCF > 1 ⇒ (GCF = 4)

The completely factored form is 4(x - 2)(x² + 2x + 4)

Step-by-step explanation:

* Lets find the greatest common factor of the two terms

- The binomial is 4x³ - 32

- The terms of the binomial are 4x³ and 32

- The greatest common factor of 4 and 32 is 4 because both of them

  can divided by 4

∵ 4x³ ÷ 4 = x³

∵ 32 ÷ 4 = 8

∴ The greatest common factor GCF is 4

∴ 4x³ - 32 = 4(x³ - 8)

* Yes there is GCF > 1

# x³ - 8 is the difference of two cubs, it can factorize it into two

  brackets

- The first bracket has cube root of x³ and cube root of 8

- The second bracket comes from the first bracket it has three terms

# The 1st term is square the 1st term in the first bracket

# The 2nd term is the product of the 1st term and the 2nd term of the

  1st bracket with opposite sign of the 2nd term in the 1st bracket

# The 3rd term is the square of the 2nd term in the 1st bracket

* Lets do these steps with x³ - 8

∵ The first bracket = (∛x³ - ∛8)

∵ ∛x³ = x and ∛8 = 2

∴ The first bracket = (∛x³ - ∛8) = (x - 2)

- Lets make the 2nd bracket from the 1st bracket

∴ The second bracket = (x² + (x)(2) + 2²)

∴ The second bracket = (x² + 2x + 4)

∴ The factorization of x³ - 8 = (x - 2)(x² + 2x + 4)

* The completely factored form is 4(x - 2)(x² + 2x + 4)

Answer:

....Yes it is 4                                                                                                                       ....4(x-2)

Step-by-step explanation:

the screenshot shows proof :))

The value of the rational expression when x is -2 or -1 is 0 and 3, respectively.

To find the value of the rational expression when x is -2 or -1, we substitute these values into the expression. Plugging in -2, we have (-2)^2 - 4/((-2)+2)((-2)+1) = 0.

Next, plugging in -1, we have (-1)^2 - 4/((-1)+2)((-1)+1) = 3.

Therefore, the value of the rational expression when x is -2 or -1 is 0 and 3, respectively.

The third angle would have to be either an obtuse angle or a right angle.

The third angle can either be an acute angle or obtuse angle

The sum of an interior angle of a triangle is 180 degrees

Acute angles are angles that are less than 90 degrees. If the two angles of a triangle are acute, the two angles can be 30 and 45 degrees

If the third angle is m<C

m<C = 180 - (30 + 45)

m<C = 180  - 75

m<C = 105 degrees

Since the angle is greater than 90 and less than 180, hence it is an Obtuse angle.

Similarly, if the two angles of a triangle are acute, the two angles can be 30 and 89 degrees

If the third angle is m<D

m<D = 180 - (30 + 90)

m<D = 180  - 119

m<D = 61 degrees

Since the angle is less than 90degrees, hence it is an acute angle.

This shows that the third angle can either be an acute angle or obtuse angle

Answer:

reciprocals

Step-by-step explanation:

Let's actually find the slopes.  Then we can better compare them.

8x - 9y = 5 → - 9y = 5 - 8x → slope is m = (-8) / (-9), or 8/9.

9x - 8y = 1  →  - 8y = 1 - 9x  → slope is (-9) / (-8), or 9/8

These two slopes are reciprocals (but not negative reciprocals).

Answer:

reciprocals, but not negative reciprocals

Step-by-step explanation:

8x - 9y = 5

9y = 8x - 5

y = 8/9x - 5/9

m1 = 8/9

9x - 8y = 1

8y = 9x - 1

y = 9/8x - 1/8

m2 = 9/8

Answer:h= [tex]\frac{(p/0.7-b)}{r}[/tex]

Step-by-step explanation:

1) p/0.7=rh+b

2) (p/0.7)-b=rh

3) [tex]\frac{(p/0.7-b)}{r}[/tex] =h

h= [tex]\frac{(p/0.7-b)}{r}[/tex]

The equivalent equation for isolated variable h = [tex]\frac{p-0.7b}{r}[/tex] obtained from the equation p = 0.7(rh + b).

Isolating a variable is the re-arrangement of the equation for the required variable. Even though rewriting the terms, doesn't affect the logic of the equation. It forms an equivalent equation.

The given equation is p = 0.7(rh + b)

Where,

p - home pay

h - working hours

r - the rate of dollars per hour

b - bonus received

Re-writing the equation for the variable h:

p = 0.7(rh + b)

⇒ p/0.7 = rh + b

⇒ p/0.7 - b = rh

⇒ h = p/0.7r -b/r

∴ h = [tex]\frac{p-0.7b}{r}[/tex]

Answer:

D:Spring A is 3 m longer than spring B because 15 – 12 = 3.

Step-by-step explanation:

In this question, you should remember the Hooke's Law in physics.

The Hooke's Law simply explains that the extension that occurs on a spring is directly proportional to the load applied on it.

The mathematical expression for this law is

[tex]F=-kx[/tex]

where;

F= force applied on the spring

x = the extension on the spring

k= the spring constant which varies in spring.

The question will need you to calculate the extension on the springs A and B then compare the values obtained.

In spring A

Force, F=60N and spring constant ,k=4 N/m

To find the extension x apply the expression;

[tex]F=-kx\\\\60=-4*x\\\\60=-4x\\\\\frac{60}{-4} =\frac{-4x}{-4} \\\\\\-15=x[/tex]

Here the spring extension is 15 m

In spring B

Force, F=60N and spring constant , k=5N/m

To find the extension x apply the same expression

[tex]F=-kx\\\\60=-5*x\\\\60=-5x\\\\\\\frac{60}{-5} =\frac{-5x}{-5} \\\\\\-12=x[/tex]

Here the extension on the spring is 12 m

Compare

The extension on spring A is 3 m longer than that in spring B because when you subtract the value of spring B from that in spring A you get 3m

[tex]=15m-12m=3m[/tex]

3. The Books

The numbers of the problem make it quite easy.

We can easily figure out how many books will be stacked in each dimension of the trunk.

Length:

Books: 10 inches

Trunk: 40 iinches.

How may books can you fit lengthwise in the trunk?  40 / 10 = 4

We then to the same for the width:

Books: 6 inches

Trunk: 24 inches

How many books can you stack wide-wise in the trunk?  26/4 = 4

And then the height:

Books: 2.5 inches

Trunk: 20 inches

How many books stacked in height? 20 / 2.5 = 8

So, we can saw the trunk is 4 books long, by 4 books wide by 8 books thick... so, the number of books you can fit in that trunk is:

B = 4 * 4 * 8 = 128

4. Tomato juice

First, we have to find the volume of that big can...

Since it's a cylinder, its volume is calculated by:

V = π * r² * h and we have everything we need:

V = 3.14 * 4² * 12 = 192 * 3.14 = 602.88 cu in

We know a cup of tomato juice takes 12 cu inches...

So, how many cups of juice fit in that can?

C = 602.88 cu in / 12 cu in/cup = 50.24 cups

Answer:

1. Number line 2

2. Number line 1

3. Number line 4

4. Number line 3

Step-by-step explanation:

1. x – 99 ≤ -104

Solving by adding +99 on both sides

x - 99 +99 ≤ -104 +99

x ≤ -5

Number line 2 represent x ≤ -5

2. x – 51 ≤ -43

Adding +51 on both sides

x -51 +51  ≤ -43 +51

x ≤ 8

Number line 1 represent x ≤ 8

3. 150 + x ≤ 144

Adding -150 on both sides

150 + x -150 ≤ 144 -150

x ≤ -6

Number line 4 represent x ≤ -6

4. 75 < 69 – x

Adding +x on both sides

75 + x < 69 -x +x

x < 69 -75

x < -6

Number line 3 represent x < -6

The correct matches are:

[tex]\(x - 99 \leq -104\)[/tex] with the number line showing [tex]\(x \leq -5\)[/tex].

[tex]\(x - 51 \leq -43\)[/tex] with the number line showing [tex]\(x \leq 8\)[/tex].

[tex]\(150 + x \leq 14475\)[/tex] with the number line showing [tex]\(x \leq 14325\)[/tex].

[tex]\(69 - x < 14475\)[/tex]  with the number line showing [tex]\(x > -14406\)[/tex].

To solve the given inequalities and match them to their corresponding number lines, we will first solve each inequality algebraically and then represent the solution on a number line.

1. For the inequality [tex]\(x - 99 \leq -104\)[/tex], we add 99 to both sides to isolate \[tex](x\)[/tex]:

[tex]\[x \leq -104 + 99\][/tex]

[tex]\[x \leq -5\][/tex]

This means that all values of [tex]\(x\)[/tex] less than or equal to -5 satisfy the inequality.

2. For the inequality[tex]\(x - 51 \leq -43\)[/tex], we add 51 to both sides:

[tex]\[x \leq -43 + 51\][/tex]

[tex]\[x \leq 8\][/tex]

This means that all values of [tex]\(x\)[/tex] less than or equal to 8 satisfy the inequality.

3. For the inequality [tex]\(150 + x \leq 14475\)[/tex], we subtract 150 from both sides:

[tex]\[x \leq 14475 - 150\][/tex]

[tex]\[x \leq 14325\][/tex]

This means that all values of [tex]\(x\)[/tex] less than or equal to 14325 satisfy the inequality.

4. For the inequality [tex]\(69 - x < 14475\)[/tex], we subtract 69 from both sides and reverse the inequality sign because we are dividing by a negative number (-1):

[tex]\[-x < 14406\][/tex]

[tex]\[x > -14406\][/tex]

This means that all values of [tex]\(x\)[/tex] greater than -14406 satisfy the inequality.

Now, let's represent these solutions on number lines:

- For [tex]\(x \leq -5\)[/tex], the number line will have a closed circle at -5 and shading to the left of -5.

- For [tex]\(x \leq 8\)[/tex], the number line will have a closed circle at 8 and shading to the left of 8.

- For[tex]\(x \leq 14325\)[/tex], the number line will have a closed circle at 14325 and shading to the left of 14325.

- For [tex]\(x > -14406\)[/tex], the number line will have an open circle at -14406 and shading to the right of -14406.

Matching the inequalities to the number lines:

- The inequality [tex]\(x - 99 \leq -104\)[/tex] corresponds to the number line with a closed circle at -5 and shading to the left.

- The inequality [tex]\(x - 51 \leq -43\)[/tex] corresponds to the number line with a closed circle at 8 and shading to the left.

- The inequality [tex]\(150 + x \leq 14475\)[/tex] corresponds to the number line with a closed circle at 14325 and shading to the left.

- The inequality [tex]\(69 - x < 14475\)[/tex] corresponds to the number line with an open circle at -14406 and shading to the right.

Therefore, the correct matches are:

[tex]\(x - 99 \leq -104\)[/tex] with the number line showing [tex]\(x \leq -5\)[/tex].

[tex]\(x - 51 \leq -43\)[/tex] with the number line showing [tex]\(x \leq 8\)[/tex].

[tex]\(150 + x \leq 14475\)[/tex] with the number line showing [tex]\(x \leq 14325\)[/tex].

[tex]\(69 - x < 14475\)[/tex]  with the number line showing [tex]\(x > -14406\)[/tex].

Answer: OPTION A.

Step-by-step explanation:

Find the length scale factor by dividing the known length of the larger triangle by the known length of the smaller triangle:

Answer:

your answer would be just x

Step-by-step explanation:

you just subtract the exponents

The expression x^-8/x^-7 simplifies to 1/x. This is due to the rule for dividing exponential expressions with the same base, which involves subtracting the exponents.

To solve x^-8/x^-7, we need to understand the rule for division of expressions with exponents which is: x^a / x^b  = x^(a-b).

When you divide exponential expressions with the same base, you subtract the exponents.

In our case, x^-8 / x^-7 = x^(-8 - -7). This simplifies to x^-1 or x^-1 = 1/x. So, the result is 1/x.

Answer:

Option C is correct.

Step-by-step explanation:

Slope of line JK

J (1,-6) K (0,4)

slope of JK = y₂ - y₁ / x₂ - x₁

Slope of JK = 4-1/0-(-6) = 3/6 = 1/2

so slope of JK = 1/2

Slope of line LM

L (-5,-3) and M(0,3)

slope of LM = y₂ - y₁ / x₂ - x₁

slope of LM = 3-(-5)/0-(-3) = 3+5/3 = 8/3

Slope of line NO

N(-6,-5) and 0 (0,0)

slope of NO = y₂ - y₁ / x₂ - x₁

slope of NO = 0-(-6)/0-(-5) = 6/5

So, slope of line NO = 6/5

Slope of PQ

P(-5,4) Q(0,-2)

slope of PQ = y₂ - y₁ / x₂ - x₁

slope of PQ = -2-4/0-(-5) = -2/5

so slope of line PQ = -2/5

the two lines are perpendicular if slope of one line is m then slope of other line is -1/m

The slope of given line =m= -5/6

The slope of line perpendicular to the given line = -1/m = 6/5

So, line NO is perpendicular to the given line as its slope is 6/5

4(-6+2z+6-2z)+1

-24+8z+24-8z+1

the 24's and 8's cancel out leaving 1

To find g(h(-3+z)), we first find h(-3+z) by substituting -3+z into h(a), it becomes z^2-8z+15. Then, substitute this into g(a) to get g(h(-3+z)), which results in 4z^2-32z+61.

In the field of Mathematics, to solve the problem g(h(-3+z)), we need to substitute h into g. It means that every 'a' in g(a) will be replaced by what h(-3+z) is equal to. To find h(-3+z), we substitute -3+z into h(a) in place of a. Therefore, h(-3+z) equals to (-3+z)^2-2(-3+z). After simplifying, it becomes z^2-6z+9+6-2z=z^2-8z+15. Next, we substitute this into g(a) to get g(h(-3+z))=4[z^2-8z+15]+1=4z^2-32z+61. Hence, the solution to the problem g(h(-3+z)) is 4z^2-32z+61.
