Answer:

[tex]x=0.79[/tex]

Step-by-step explanation:

we have

[tex]-5(10^{x})=-31[/tex]

step 1

Divide by -5 both sides

[tex]10^{x}=31/5[/tex]

step 2

Apply log both sides

[tex]log[10^{x}]=log[31/5][/tex]

step 3

Applying Property of logarithms

Remember that

[tex]log(x^{y})=ylog(x)[/tex]

so

[tex]xlog[10]=log[31/5][/tex]

Remember that

[tex]log(10)=1[/tex]

substitute

[tex]x=log[31/5][/tex]

[tex]x=log(6.2)[/tex]

[tex]x=0.79[/tex]

The answwe is that 5 is 50 and 5 is 5, giv the other user brainliest tho...

One line has a positive slope and the other a negative slope, they are bound to intercept eventually, so that's why there can't be zero solutions. Two lines can't intercept each other twice, and if they have opposite slopes they can't have infinite solutions.

First quadratic equation whose graph open upward is

[tex]ax^{2} + bx + c = 0[/tex] , where (a≠0)

when a>0 is positive the graph upward .

And second quadratic equation whose graph open downwards is

Answer:

1.6 miles

Step-by-step explanation:

60/12=5

which will mean 1/5=.2

.2x8=1.6 miles

Tina's running rate is 8 miles per hour. In 12 minutes, she will cover a distance of 1.6 miles.

To calculate the number of miles Tina will run in 12 minutes, we need to convert the time to hours since her rate is given in miles per hour.

Since there are 60 minutes in an hour, we divide 12 minutes by 60 to convert it to hours:

12 minutes / 60 = 0.2 hours

Now, we can calculate the distance Tina will run by multiplying her rate by the time:

Distance = Rate * Time = 8 miles per hour * 0.2 hours

Distance = 1.6 miles

Therefore, Tina will run 1.6 miles in 12 minutes.

Answer:

m=1.1

Step-by-step explanation:

Divide one side by 8, then you get 7:(4/11 m)=7: 0.4

Basically then 4/11 m=0.4

4/11 m=2/5

m=(11/4)(2/5)

m=11/10, 1 1/10, 1.1

The value of m that satisfies the proportion 7:(4/11 m) = 56:3.2 is 1.1

From the question, we have the following parameters that can be used in our computation:

7: (4/11m) = 56 : 3.2

Cross-multiply the proportions

7 * 3.2 = (4/11 m) * 56

Simplify both sides:

22.4 = (4/11 m) * 56

Divide both sides by 56

(4/11 m) = 22.4 / 56

Simplify the right side

(4/11 m) = 0.4

Multiply both sides by (11/4)

m = 0.4 * (11/4)

So, we have

m = 1.1

Hence, the calculated value of "m" that satisfies the proportion 7:(4/11 m) = 56:3.2 is 1.1

Answer:

  Greg is correct. 3.3 has a finite number of digits

Step-by-step explanation:

A "non-terminating" decimal is one with an infinite number of digits. If you can actually count the digits, it is a terminating decimal. 3.3 has 2 digits, so is a terminating decimal. Greg is correct.

__

A terminating or repeating decimal is a rational number.

  [tex]3.3 \quad\text{a terminating decimal equal to $\dfrac{33}{10}$}\\\\ 3.\overline{3} \quad \text{a non-terminating rep}\text{eating decimal equal to $\dfrac{10}{3}$}[/tex]

Using the concept of rational numbers, it is found that 5.3 is a rational number, as it is a terminating decimal, and thus, Greg is correct.

Answer:

100

Step-by-step explanation:

You are given the equation

[tex]4x-4.5=10.73+5.7+7x[/tex]

There are 5 coefficients:

[tex]4, \ -4.5,\ 10.73,\ 5.7,\ 7[/tex]

Two of them are integers

[tex]4,\ 7[/tex]

two of them are decimals with one digit after point

[tex]-4.5,\ 5.7[/tex]

and one is a decimal with two digits after point

[tex]10.73[/tex]

To get rid of fractions, we have to get rid of digits after point. The maximum number of digits after point is 2, then we have to multiply the equation by 100:

[tex]400x-450=1,073x+570+700x[/tex]

Final answer:

To eliminate decimals in an equation, multiply all terms by a power of 10 to shift the decimals to whole numbers, simplifying the calculation process.

Explanation:

To get rid of decimals in the equation 4x - 4.5 = 10.73x + 5.7 + 7x, you would multiply each term by a power of 10 that shifts the decimals to whole numbers. By determining the highest number of decimal places in the terms, you can multiply all terms by a suitable power of 10.

For example, if the highest number of decimal places is 2, you would multiply all terms by 100. This action shifts the decimals two places to the right, converting them into whole numbers and simplifying the equation.

By multiplying all terms by the appropriate power of 10, you eliminate decimals and work with whole numbers, making it easier to solve the equation.

The resulting expression for (3⁰+2⁰)×5⁰ is 1

Before we solve the tabled algebra problem, we must understand that any value raise to the power of zero is 1.

Given the expression

(3⁰+2⁰)×5⁰

Since all the integers are raised to power of zero, hence;

3⁰ = 1

2⁰ = 1

5⁰ = 1

Substitute this values into the given expression

= (3⁰+2⁰)×5⁰

= (1+1)×1

= 1 × 1

= 1

Hence the resulting expression for (3⁰+2⁰)×5⁰ is 1

Now raise [x^(1/5)] to the 9th power.

[x^(1/5)]^(9)

Multiply the powers to complete the problem.

x^(9/5)

Answer: Choice B.

The expression 'fifth root of x to the power of 9' can be rewritten as 'x to the 9/5 power' in terms of rational exponents, this is option b.

The correct rewrite of the expression, 'fifth root of x to the power of 9', utilizing rational exponents instead of a radical approach, is expressed as x to the 9/5 power. When translating a radical to a rational exponent, the index of the root becomes the denominator and the power of the term inside the root becomes the numerator.

So, fifth root of x to the power of 9 translates to x to the power of 9/5, which corresponds to option b.

Answer:

- 1, 1, - 3

Step-by-step explanation:

To obtain the value of f(1), we require the corresponding value of y from the graph when x = 1

From the graph

when x = 1 the value of y on the graph is - 1 ⇒ f(1) = - 1

Similarly

f(3) means what is the value of y corresponding to x = 3

From the graph when x = 3 then y = 1 ⇒ f(3) = 1

and f(- 1) = - 3

Answer:

100 inches Over 1 minute times × 1 foot Over 12 inches

Step-by-step explanation:

Remember that

[tex]1\ ft=12\ in[/tex]

so

[tex]1\ in=1/12\ ft[/tex]

we have

[tex]100\frac{in}{min}[/tex]

Convert to ft/min

To convert in/min to ft/min multiply the given value by the factor 1/12

[tex]100\frac{in}{min}(1/12)\frac{ft}{in}=8.33\ ft/min[/tex]

therefore

100 inches Over 1 minute times × 1 foot Over 12 inches

100 inches Over 1 minute times × 1 foot Over 12 inches, the correct answer is 3.

We know that,

1ft = 12inches

So, 1 in. = 1/12 ft

We have expression converts 100 inches per minute to feet per minute

100 inches/min

To convert in/min to ft/min multiply the given value by the factor 1/12

100  inches/min (1/12 ft/in)

Therefore, 100 inches Over 1 minute times × 1 feet Over 12 inches

Step-by-step explanation:

The vertices of pentagon PQRST are P(0, 1), Q(2, 2), R(5, 3), S(4, 0), and T(1,−1).

If a figure reflected across y-axis, then the relation between preimage and  image is

[tex](x,y)\rightarrow (-x,y)[/tex]

If the pentagon PQRST reflected over the y-axis, then vertices of image are

1. Volume of a cylinder is πr^2h

Area of the base would be πr^2

Volume would be the height x the area of the base:

Volume = 5 x 20 = 100 cubic in.

2. Divide the volume by the area:

B - base area

h - height

1. We have

h = 5in, B = 20 in².

Substitute:
