how many solutions does 9x+3=9x+5 have?​

Answer:

m∠1 = (a + b) you will also need to divide the sum by 2

Step-by-step explanation:

The measures of angles formed by intersecting chord can be found by adding their arc measures and dividing in 2.

In this case, m< 1 = 1/2 ( a + b).

Based on the angle of intersecting chords theorem, the equation of that can be used to solve m∠1 is: m∠1 = 1/2(a + b).

The angle of intersecting chords theorem states that the measure of any of the vertical angles formed when two chords intersect equals half of the sum of the two intercepted arcs.

Therefore, based on the angle of intersecting chords theorem, the equation of that can be used to solve m∠1 is: m∠1 = 1/2(a + b).

Final answer:

To use order numbers in different forms, you convert between fractions, decimals, and percents. For example, to convert from percent to decimal, you divide by 100; to convert from decimal to percent, you multiply by 100.

Explanation:

You can use order numbers that are written as fractions, decimals, and percents for various mathematical and real-life applications. They are different ways to represent the same value, and you can convert between them. For example, to convert a percent to a decimal, you write the value of the percent as a fraction with a denominator of 100 and divide the numerator by the denominator. Similarly, to convert a decimal to a percent, you write the decimal as a fraction. If the denominator of the fraction is not 100, convert it to a fraction with a denominator of 100, then write the fraction as a percent.

Example of Converting Percents

To convert 75% to a decimal, write it as 75/100, which simplifies to 0.75. Conversely, to convert 0.75 to a percent, you multiply by 100 to get 75%.

Answer: The correct answer is 3.

Step-by-step explanation:

You need to write an equation to solve this problem, using x as the number of personal training sessions.

The equation to solve this problem is

35 + 25 x = 65 + 15x

First, subtract 35 from both sides:

25x = 30 + 15x

Subtract 15x from both sides:

10x = 30

The last step is to divide both sides by 10:

x = 3

You can then double check your work to make sure that the answer is correct:

35 + (25 x 3) = 110

65 + (15 x 3) = 110

To solve 3x^2(9x)^0, simplify the expression inside the parentheses first, then multiply by 3x^2.

To solve the equation 3x2(9x)0, we can simplify the expression inside the parentheses first. Any number raised to the power of 0 is equal to 1. So, (9x)0 becomes 1. Now we have 3x2 * 1. Multiplying any number by 1 doesn't change its value, so the equation simplifies to 3x2.

Answer:

x = 60°

Step-by-step explanation:

This is an equilateral triangle. All angles of this triangle are congruent and have a measure of 60°.

Other method.

We know: the sum of the measures of the angles of the triangle is equal to 180 °.

Therefore we have the equation:

x + x + x = 180°

3x = 180°           divide both sides by 3

x = 60°

Answer:

B option. AB is larger than FD

Step-by-step explanation:

The rule which must be remembered here is:

The side opposite to the larger angle will be larger in measure. We have to compare two sides that are opposite to two angles 72 and 65.

So using the above rule we can say that side opposite to angle 72 will be greater in measure than the side opposite to 65.

The side opposite to 72 is AB and side opposite to 65 is FD.

Therefore, we can conclude that AB is larger in measure than FD, which makes option B as the correct answer,

Answer:

The correct answer option is AB is longer than FD.

Step-by-step explanation:

We are given two triangles, ΔABC and ΔDEF, where AC ≅ FE and BC ≅ DE.

One out of three angles is known for each triangle: ∠ACB = 72° and ∠DEF = 65° and we are to determine which of the statements is correct about AB and FD.

We know that the side opposite to the bigger angle is longer. Since ∠C = 72° is greater than ∠E, therefore side AB is longer than FD.

Answer:

5 dozen hot dogs

Step-by-step explanation:

Erica started with 80 dozen hot dogs.

To determine what she sold, take what she started with and subtract what she ended with

80-75 = 5

She sold 5 dozen hot dogs

The length is 13 and width is 8

Let the length is L

Width will be L-5

Area of rectangle = Length x Width

Putting the values

104 = L x L-5

104=l(l−5)

Simplify both sides of the equation.

104=l²−5l

Subtract l²-5l from both sides.

104−(l²−5l)=l²−5l−(l²−5l)

−l²+5l+104=0

Factor left side of equation.

(−l−8)(l−13)=0

Set factors equal to 0.

−l−8=0 or l−13=0

l=−8 or l=13

We will take l = 13 because length cannot be negative

Now for width we know that w = l -5

So width is 13 -5 = 8

Answer:

(D) [tex]8.46\cdot 3.51^x[/tex]

Step-by-step explanation:

One could run this on a computer and verify the best fit through brute force. The more elegant way is, as usual, to think: What are special values of x for an exponential function? Zero, for starters - anything to the power of zero is 1. The function value for x=0 in the table is 10. Which choices A through D are close to 10 for x=0? Well, (C) and (D), the rest is too far. Next, what is the function value for the next easy one, x=1? The table says 30. Which of (C) and (D) is close to 30 for x = 1. It turns out we can safely exclude (C) because 10.84*1.77 is about 19 and that's way too far from 30. Let's check (D): 8.46*3.51=29.7 - that's quite close. Since there is no other candidate left, I bet my money on (D). Feel free to verify closeness for the other values of x if you are unconvinced yet.  

Answer:

[tex]\text{D. }y = 8.46(3.51)^{x}[/tex]

Step-by-step explanation:

The quickest way is probably to do some direct substitution.

First, let's try f(0).

The values of y predicted by the four equations are, respectively, 3.14, 5.32. 10.84, and 8.46.

It looks like C and D are the closest to the observed data.

Now, let's try f(4) on C and D.

C: 10.84(1.77)⁴ = 10.84 × 9.815 = 106.4

D:  8.46(3.51)⁴ =    8.46 × 151.4 = 1284

The best curve is [tex]y = 8.46(3.51)^{x}.[/tex]

Answer:

Step-by-step explanation:

Total Number of animals = 23 + 27 = 50

Number of Dogs = 27

Percentage of dogs = [tex]\frac{27}{50}[/tex] × 100 = 54%

The percentage of dogs will be 54%.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Number of cats = 23

Number of dogs = 27

Now,

Total number of animals = 23 + 27

                                      = 50

And, Number of dogs = 27

Hence, The percentage of dogs = (27/50) × 100

                                                  = 54%

Thus, The percentage of dogs will be 54%.

Answer: D) All of these are correct

Answer:

D. All of these are correct

Step-by-step explanation:

She needs four inches of ribbon and each spool has 24 inches, so we can write this equation like:

384/24 = s

where s is the number of spools.

If we divide 384 inches by the 24 inches each spool has she will get how many spools she needs.

Now having the equation: 384/24 = s, we can change it and it will mean the same.

384/24 = s  is the same as 24s = 384; just sending the 24 to multiply on the other side.

And it is the same as 384/s = 24 just sending the s to the other side dividing.

So all of the answers are correct they are just in different orders.

Isabella uses the equation [tex] V = \frac { 1 } { 3 } ( 12 ) ^ 2 ( 9 ) \pi [/tex] and we are to find the error that she is making in finding the volume of this cone.

The volume of a cone is given by: [tex]\pi r^2\frac{h}{3}[/tex] out of which [tex]\pi r^2[/tex] represents the area of the base (circle).
