Answer:

x = 6 weeks

Step-by-step explanation:

We'll let x represent the number of weeks it will take to save enough money. If she saves $11 each week, then in x weeks she will save  11x dollars.

Add this to the 107 she has already saved, and at the end of 11 weeks she will have    11x + 107 dollars.

We want the amount saved to be equal to the price of the bike, so our equation is

11x + 107 = 173

In a word problem, writing the equation is usually the hardest part. Now we solve the equation.

Subtract 107 from both sides to get

11x = 66

Divide both sides by 11 to get

x = 6 weeks

The standard form of the number will be 7.90 x 10¹².

A number can be expressed in a fashion that adheres to specific standards by using its standard form. Standard form refers to any number that may be expressed as a decimal number between 1.0 and 10.0 when multiplied by a power of 10.

Given that the number is 7.901 x 10¹². The number is already in standard form. The number will be written in normal form as below:-

7.901 x 10¹² = 7901000000000

Therefore, the standard form of the number will be 7.90 x 10¹².

Answer:

[tex](-13) * (-13) = (-13)^{2}[/tex]

[tex]35 * 35 = 35^{2}[/tex]

Step-by-step explanation:

Given

[tex](-13) * (-13)[/tex]

Required

Express as an exponential notation

[tex](-13) * (-13)[/tex]

Apply the following law of indices

[tex]x^a * x^b = x^{a+b}[/tex]

This gives:

[tex](-13) * (-13) = (-13)^{1+1}[/tex]

[tex](-13) * (-13) = (-13)^{2}[/tex]

The second complete is incomplete; However, I'll assume it is: 35 times 35

[tex]35 * 35[/tex]

Using the same law applied in (1) above:

[tex]35 * 35 = 35^{1+1}[/tex]

Answer:

The height of the building is 18.8 feet to the nearest tenth

Step-by-step explanation:

Whenever an elevation problem is given the first step is to try to visualize a triangular path between the objects that are given in the problem.

In this case, we can form a triangular path between the man, the top of the building, and the ground.

The height of the building we are looking for will be the opposite side of the triangle because it is directly facing the angle: 38 degrees.

The distance 24 feet will be the adjacent side of the triangle because it is adjacent to that angle

We can use the Tan trigonometric relationship to find a relationship between the length of the sides of the triangle and the available angles.

[tex]tan 38 = height/24ft[/tex]

[tex]height = 24 \times tan38 = 18.75ft[/tex] approximately 18.8 ft

Answer:

Any value of x

Step-by-step explanation:

Given

[tex]f(x) = \sqrt{x^2 - 1}[/tex]

[tex]g(x) = \sqrt{x^2 + 1}[/tex]

Required

What value of x is  [tex]f(g(x)) = g(f(x))[/tex]

Solving for f(g(x))

[tex]f(x) = \sqrt{x^2 - 1}[/tex]

[tex]f(g(x)) = \sqrt{(\sqrt{x^2 + 1})^2 - 1}[/tex]

Solve the inner square

[tex]f(g(x)) = \sqrt{(x^2 + 1 - 1}[/tex]

[tex]f(g(x)) = \sqrt{x^2 } }[/tex]

[tex]f(g(x)) = x[/tex]

Solving g(f(x))

[tex]g(x) = \sqrt{x^2 + 1}[/tex]

[tex]g(f(x)) = \sqrt{(\sqrt{x^2 - 1})^2 + 1}[/tex]

[tex]g(f(x)) = \sqrt{x^2 - 1 + 1}[/tex]

[tex]g(f(x)) = \sqrt{x^2 }[/tex]

[tex]g(f(x)) = x[/tex]

Equate f(g(x)) and g(f(x))

[tex]f(g(x)) = g(f(x))[/tex]

[tex]x = x[/tex]

This implies that [tex]f(g(x)) = g(f(x))[/tex] at any value of x

Answer:

8

Step-by-step explanation:

10+8-6-4=8

Answer:

If the segment is horizontal or vertical, you can find the midpoint by dividing the length of the segment by 2 and counting that value from either of the endpoints. Example 1: Given the graph at the right, find the midpoint of and of . AB = 4 units (by counting). The midpoint is 2 units from either endpoints.

Add n on both sides:

3m = km - 8 + n

Subtract km on both sides:

3m - km = n - 8

Factor the Left-Hand Side:

m(3 - k) = n - 8

Divide both sides by (3 - k):

m = (n - 8) / (3 - k)

Answer:

(8-n)/(k-3) =m

Step-by-step explanation:

3m-n=km-8

Subtract 3m from each side

3m -3m-n=km -3m-8

-n =km -3m-8

Add 8 to each side

8-n =km -3m-8+8

8-n =km -3m

Factor out m

8-n =m(k -3)

Divide by (k-3)

(8-n)/(k-3) =m(k -3)/( k-3)

(8-n)/(k-3) =m

Answer:

Step-by-step explanation:

From the given rectangle,

Length of the rectangle = 5 cm

Width of the rectangle = 10 cm

Ratio of length : width = 1 : 2

Perimeter of the rectangle = 2(l + b)= 150 cm

l + b = 75 -----(1)

Since, l : b = 1 : 2

[tex]\frac{l}{b}= \frac{1}{2}[/tex]

b = 2l ------(2)

From equations (1) and (2),

l + 2l = 75

3l = 75

l = 25 m

Width 'b' = 2(25) = 50 m

Now we have to draw a rectangle with a scale = 25 : 2

Therefore, Scale factor = [tex]\frac{25}{l}=\frac{25}{2}[/tex]

l = 2 cm

Similarly,

[tex]\frac{50}{w}=\frac{25}{2}[/tex]

w = 4 cm

Now we can draw a rectangle with length = 2 cm and width = 4 cm.

Answer:

[tex]12942[/tex] is the sum of positive integers between [tex]1[/tex] (inclusive) and [tex]199[/tex] (inclusive) that are not multiples of [tex]4[/tex] and not multiples [tex]7[/tex].

Step-by-step explanation:

For an arithmetic series with:

there would be [tex]\displaystyle \left(\frac{a_n - a_1}{d} + 1\right)[/tex] terms, where as the sum would be [tex]\displaystyle \frac{1}{2}\, \displaystyle \underbrace{\left(\frac{a_n - a_1}{d} + 1\right)}_\text{number of terms}\, (a_1 + a_n)[/tex].

Positive integers between [tex]1[/tex] (inclusive) and [tex]199[/tex] (inclusive) include:

[tex]1,\, 2,\, \dots,\, 199[/tex].

The common difference of this arithmetic series is [tex]1[/tex]. There would be [tex](199 - 1) + 1 = 199[/tex] terms. The sum of these integers would thus be:

[tex]\begin{aligned}\frac{1}{2}\times ((199 - 1) + 1) \times (1 + 199) = 19900 \end{aligned}[/tex].

Similarly, positive integers between [tex]1[/tex] (inclusive) and [tex]199[/tex] (inclusive) that are multiples of [tex]4[/tex] include:

[tex]4,\, 8,\, \dots,\, 196[/tex].

The common difference of this arithmetic series is [tex]4[/tex]. There would be [tex](196 - 4) / 4 + 1 = 49[/tex] terms. The sum of these integers would thus be:

[tex]\begin{aligned}\frac{1}{2}\times 49 \times (4 + 196) = 4900 \end{aligned}[/tex]

Positive integers between [tex]1[/tex] (inclusive) and [tex]199[/tex] (inclusive) that are multiples of [tex]7[/tex] include:

[tex]7,\, 14,\, \dots,\, 196[/tex].

The common difference of this arithmetic series is [tex]7[/tex]. There would be [tex](196 - 7) / 7 + 1 = 28[/tex] terms. The sum of these integers would thus be:

[tex]\begin{aligned}\frac{1}{2}\times 28 \times (7 + 196) = 2842 \end{aligned}[/tex]

Positive integers between [tex]1[/tex] (inclusive) and [tex]199[/tex] (inclusive) that are multiples of [tex]28[/tex] (integers that are both multiples of [tex]4[/tex] and multiples of [tex]7[/tex]) include:

[tex]28,\, 56,\, \dots,\, 196[/tex].

The common difference of this arithmetic series is [tex]28[/tex]. There would be [tex](196 - 28) / 28 + 1 = 7[/tex] terms. The sum of these integers would thus be:

[tex]\begin{aligned}\frac{1}{2}\times 7 \times (28 + 196) = 784 \end{aligned}[/tex].

The requested sum will be equal to:

That is:

[tex]19900 - 4900 - 2842 + 784 = 12942[/tex].

Answer:

Yes, ratios of blue paint to yellow paint form a proportional relationship

Step-by-step explanation:

In case of the first person:

Number of blue parts = 2

Number of yellow parts [tex]=3[/tex]

In case of another person:

Number of blue parts [tex]=4[/tex]

Number of yellow parts [tex]=6[/tex]

Ratio of blue parts [tex]=2:4=1:2[/tex]

Ratio of yellow parts [tex]=3:6=1:2[/tex]

As ration of blue parts is equal to the ratio of yellow parts, ratios of blue paint to yellow paint form a proportional relationship

Answer:

x = 9

Step-by-step explanation:

2x + 3(6)= 36

2x + 18= 36

    - 18    - 18

2x = 18

divide by 2

x= 9

x = 145°

the sum of interior angles of octagon formula

S = (n - 2)×180°

n = 8

S = (8 - 2)×180°

S = 6×180°

S = 1080°

we have 1 angle = 65° & others are equal to each other

1080° - 65° = 7x

7x = 1015°

x = 1015° : 7

x = 145°

Answer:

D) The square root of a positive number can be a negative or positive value.

Step-by-step explanation:

36 is a perfect square, meaning that the square root of 36 is equivalent to an integer, 6, whereby, the integer 6, when multiplied by itself gives us the perfect square, 36.

i.e. 36 = 6*6 = 6²

√36 = √6² = 6

There are actually two possible square root of 36. That is -6.

Square of, -6², equivalently is -6 * -6 = 36.

Therefore, √36 = ±6.

So, her claim is wrong. 6 is not the only square root of 36.

Square root of 36 could be negative 6 or positive 6.
