how many times larger is 9 X 10 to the 6 exponent than 3 x 10 to the 4th exponent

10, 267

the fraction of voters opposed from the survey = [tex]\frac{250}{974}[/tex]

Assuming this fraction as a basis then the predicted number against will be

40, 000 × [tex]\frac{250}{974}[/tex] = 10, 267 ( nearest while number )

Answer:

7x+6 = 5(x+6)

Step-by-step explanation:

x represents Harry's age now, so 7x represents Nick's age now. (Nick is 7 times as old as Harry.)

In 6 years, Harry's age will be x+6.

In 6 years, Nick's age will be 7x+6, which is 5 times Harry's age at that time, 5(x+6). Hence an appropriate equation is ...

... 7x+6 = 5(x+6)

_____

Please note that finding the value of x does not give the answer to the question. We are asked for Harry's age in 6 years, so the answer is x+6 (=18).

Solution:

We can graph using the intercepts:

(1) y-intercept, when x=0

y=4x-3→y=4(0)-3→y=0-3→y=-3

Point=(x,y)=(0,-3)

(2) x-intercept, when y=0

y=4x-3→0=4x-3

Solving for x: Adding 3 both sides of the equation:

0+3=4x-3+3

3=4x

Dividing both sides of the equation by 4:

3/4=4x/4

3/4=x

x=3/4=0.75

Point=(x,y)=(3/4,0)=(0.75,0)

With these pair of points (0, -3) and (0.75,0) we can draw the right line

Answer:

C thank you next

Step-by-step explanation:

Answer: First option. y-15=5(x-3)

Solution:

We can take any pair of points of the table. For example:

P1=(3, 15)=(x1, y1)→x1=3, y1=15

P2=(5, 25)=(x2,y2)→x2=5, y2=25

And we can find the slope m using the following formula:

m=(y2-y1)/(x2-x1)

m=(25-15)/(5-3)

m=(10)/(2)

m=5

Now we can apply the point-slope formula to find the equation of the right line:

y-y1=m(x-x1)

Replacing y1=15, m=5, and x1=3

y-15=5(x-3)

The equation in point-slope form that represents the plant's growth over time would be 'y - 9 = 3x', given that the y-intercept is 9 and the slope is 3.

Based on the information given, it is clear that the y-intercept where the line intersects the y-axis is 9 and the slope of the line is 3. We know that y stands for the height of the plant and x for time in months. Using these values, the equation in point-slope form, which is normally written as y - y1 = m(x - x1) where m is the slope and (x1, y1) is a given point on the line, can be simplified assuming that x1=0 and y1 is our y-intercept which is 9.

Therefore, the equation of the line that represents the growth of the plant over time in point-slope form would be y - 9 = 3x.

This question is one where the numbers don't add up. You should ask your teacher to show you how to work it.

___

Let n, d, q represent the numbers of nickels, dimes, and quarters Landau has, respectively.

... d = 7n +3 . . . . . the number of dimes is 3 more than 7 times the number of nickels

... q = 2n -4 . . . . . the number of quarters is 4 less than 2 times the number of nickels

... 5n +10d +25q = 330 . . . . the total value of the coins is 330 cents

Using the first two equations to substitute into the last one, we get

... 5n +10(7n +3) +25(2n -4) = 330

... 125n -70 = 330 . . . . . . eliminate parentheses, collect terms

... n = 400/125 . . . . . . . . add 70, divide by 125

... n = 3.2

... d = 7·3.2 +3 = 25.4

... q = 2·3.2 -4 = 2.4

Landau has 3.2 nickels, 25.4 dimes, and 2.4 quarters.

24.75 i just had this question got it wrong but there's the correct answer

Angle D is 180° -75° -45° = 60°. Drawing altitude MX to segment DN divides the triangle into ΔMDX, a 30°-60°-90° triangle, and ΔMNX, a 45°-45°-90° triangle. We know the side ratios of such triangles (shortest-to-longest) are ...

... 30-60-90: 1 : √3 : 2

... 45-45-90: 1 : 1 : √2

The long side of ΔMDX is 10√3, so the other two sides are

... MX = MD(√3/2) = 15

... DX = MD(1/2) = 5√3

The short side of ΔMNX is MX = 15, so the other two sides are

... NX = MX(1) = 15

... MN = MX(√2) = 15√2

Then the perimeter of ΔDMN is ...

... P = DM + MN + NX + XD

... P = 10√3 +15√2 + 15 + 5√3

... P = 15√3 +15√2 +15 . . . . perimeter of ΔDMN

The Perimeter of △DMN is 35.9

First step

sin 45 / 10 = sin 60/ x

x = sin 60 × 10 / sin 45

= √(3)/2 × 10 × 2 / √(2)

= √(3) / 2 × 10 ×√(2)

= 5 × √(6)

Second step

sin 45 / 10 = sin 75 / y

y = sin 75 × 10 / sin 45

= sin 75 × 10 × 2 / √(2)

= sin 75 × 10 ×√(2)

= 13.066054

Now let determine Perimeter of △DMN

Perimeter of △DMN=10 + 5*√(6) + 13.06605425

Perimeter of △DMN= 35.90770275                      

Perimeter of △DMN=35.9

Answer:

22.9 m

Step-by-step explanation:

Circumference = π × diameter

Using a calculator to evaluate 7.3π, we get 22.933626...

Rounding this to the nearest tenth gives 22.9. Units are meters.

The circumference of a circle with a diameter of 7.3m is approximately 22.9 meters.

The circumference of a circle is calculated by using the formula C = πd, where 'C' is the circumference and 'd' is the diameter. Given that the diameter of the circle is 7.3 m, you can plug this value into the formula to find the circumference.

So, C = π × 7.3

To find the circumference of a circle with diameter 7.3m, we can use the formula C = π x d, where C is the circumference and d is the diameter. Plugging in the given value, we get C = 3.14 x 7.3 = 22.922. Rounding to the nearest tenth, the circumference is approximately 22.9 meters.

This equation does not factor, but we can solve using the quadratic formula

x = ( - b ± √(b² - 4ac) )/ 2a

given the equation in standard form : ax² + bx + c = 0

divide through by - 1, to obtain

x² + 7x + 2 = 0

with a = 1, b = 7 and c = 2, then

x = ( - 7 ± √(49 - 8) ) / 2

x = - [tex]\frac{7}{2}[/tex] ± √41 / 2 → (d)

Finding real roots of higher-degree polynomials is often done most easily with the help of a graphing calculator.

x = 2x + 1

x - 2x = 1

-x = 1

x = -1

Solution :

Given , function[tex]f(x) = 2x+1[/tex]

we have to find the inverse of the function f(x)

Substitute y for f(x):  [tex] y=2x+1[/tex]

Subtract 1 from both sides, [tex]y-1=2x+1-1[/tex]

Divide both sides by 2, [tex]\frac{y-1}{2} = x[/tex]

[tex]\Rightarrow x=\frac{y-1}{2}[/tex]

Substitute [tex]f^{-1}(y)\:for\:x [/tex][tex]\RIghtarrow f^{-1}(y)=\frac{y-1}{2}[/tex]

Hence, The inverse of the function [tex]f(x)=2x+1\:is f^{-1}(y)=\frac{y-1}{2}[/tex]

4!(7 – 4)! is equivalent to (4!)(3)!

3! = 3*2*1 = 6, and 4! = 4(6) = 24.

The values of x and y are x=10, y=50.

_____

AB = 6x+30 = 90

BC = 2x-5 = 15

This is because the total needs to be equal to 180 degrees. Since obtuse angles are greater than 90 degrees, then it needs an acute angle (lower than 90 degrees) to supplement it to equal 180

Answer:

Step-by-step explanation:

An angle bisector divides the angle into equal halves.

Given that:

[tex]\angle ABD = 52^o[/tex]

From the question, we understand that:

BC bisects [tex]\angle ABD[/tex]

This means that:

[tex]\angle ABD = 2 \times \angle ABC[/tex] ---- By definition of midpoint

So, we have:

[tex]52^o= 2 \times \angle ABC[/tex] ---- By substitution property

Divide both sides by 2

[tex]26^o= \angle ABC[/tex] ---- By division property of equality

So, we have:

You can write equations for total pay, but in the end, you want to find the amount of sales that makes the difference in commission make up for the difference in base pay.

... (commission rate difference) × sales = (base pay difference)

To find the sales, divide by its coefficient:

... sales = (base pay difference)/(commission rate difference)

Sales = (20,000 -17,000)/(.12 -0.05) = 3000/0.07 ≈ 42,857.14

You need to sell more than $42,857.14 for option A to pay more.

Sales = (25,000 -20,000)/(.09 -.03) = 5000/0.06 ≈ 83,333.33

You need to sell more than $83,333.33 for option A to pay more.

_____

In each case, total pay is ...

... total pay = (base pay) + (commission rate) × sales

For the two options to give the same total pay, the difference in total pay is zero. That occurs when ...

... 0 = (base pay₁) + (commission rate₁) × sales -((base pay₂) + (commission rate₂) × sales)

... 0 = (base pay₁) - (base pay₂) - sales × ((commission rate₁) -(commission rate₂))

Solving for sales, we get the above result:

... sales = ((base pay₂) -(base pay₁))/((commission rate₁) -(commission rate₂))

Solution 8:

We are given base salary of 17000 and 12% of sales.

Les us say salesperson does sales of x amount.

So 12% of x is 0.12x

Total salary = 17000+0.12x

In second case base salary is $20000 and commission of 5% of sales.

Total salay=20000+0.05x

Now for option A to pay more we have:

[tex]17000+0.12x>20000+0.05x[/tex]

Solving we get:

[tex]0.07x>3000[/tex]

x>42,857

Answer: Option A need to make sales of $42,857 more.

Solution 9:

We are given base salary of 20000 and 9% of sales.

Les us say salesperson does sales of x amount.

So 9% of x is 0.09x

Total salary = 20000+0.09x

In second case base salary is $25000 and commission of 3% of sales.

Total salay=25000+0.03x

Now for option A to pay more we have:

[tex]20000+0.09x>25000+0.03x[/tex]

Solving we get:

[tex]0.06x>5000[/tex]

x>83,333.33
