Four times the sum of half a number and 6 is 48.
How do you put this as an equation?

Answer/Step-by-step explanation:

To simplify the given expressions that involves negative exponent, recall the law of exponents that deals with simplifying negative exponent.

Thus: [tex] a^{-x} = \frac{1}{a^x} [/tex]

Ally this rule in solving the given problem as follows:

Red blood cell = [tex] 125,000^{-1} = \frac{1}{125,000^1} = \frac{1}{125,000} = 0.000008 = 8*10^{-6} [/tex]

White blood cells = [tex] 3(500)^{-2} = 3(\frac{1}{500^2}) = 3(\frac{1}{250,000}) = 3*0.000004 = 0.000012 = 1.2*10^{-5} [/tex]

Platelet = [tex] 3(1000)^{-2} = 3(\frac{1}{1,000^2}) = 3(\frac{1}{1,000,000}) = 3*0.000001 = 0.000003 = 3*10^{-6} [/tex]

Perform an experiment

Step-by-step explanation:

The experiments state that it is the test which is to be carried to confirm or refute the hypotheses they had about a specific subject. Therefore, the study findings will be based on the outcome of these experiments.

Answer:

[tex][15: (3 \times 5) + 4] \times 8[/tex]

Step-by-step explanation:

First of all, let us have a look at the rule for solving brackets/parentheses/algebraic operations.

The rule states that the expression must be solved in the following order:

B - Brackets (Innermost parentheses first, then the enclosing brackets are solved)

O - Of (for example 10% of 20)

D - Divide operation

M - Multiplication operation

A - Addition operation

S - Subtraction operation

So, we need to add a set of parentheses i.e. () and a set of brackets i.e. [] in the expression:

[tex]15: 3 \times 5 + 4 \times 8[/tex] such that the result is 40.

Consider the expression: [tex][15: (3 \times 5) + 4] \times 8[/tex]

Let us try to solve the expression using the above rule:

[tex][15: (3 \times 5) + 4] \times 8[/tex]

First of all, the innermost () will be solved:

[tex](3\times 5) = 15[/tex]

Now, the expression becomes:

[tex][15: 15 + 4] \times 8[/tex]

Now, 15:15 will be solved as 1

[tex][1+ 4] \times 8[/tex]

Now, the outer [] will be solved:

[tex]5\times 8 = 40[/tex]

Hence, the correct answer is:

[tex][15: (3 \times 5) + 4] \times 8[/tex]

Answer:

At my school 20 people boys and girls play soccer

Answer:

250 m

Step-by-step explanation:

Let the total length be x m.

[tex] \therefore \: \frac{3}{5} \times x = 210 \\ x = 210 \times \frac{5}{3} \\ x = 70 \times 5 \\ x = 350 \: m \\ \\ \frac{5}{7} \times x = \frac{5}{7} \times 350 = 5 \times 50 = 250 \: m[/tex]

Step-by-step explanation:

(Sorry in advanced. I haven't done this stuff in a while.)

It's basically asking for the numbers in between each number. Thing is that the symbols on each end makes all numbers positive. Looking at the graphs, there are none with all positives.

I'm very sorry if this isn't right but I believe its the correct answer. Tell me if it is!

Answer:

[tex]\sqrt{45}[/tex]

Step-by-step explanation:

We can use the distance formula to find the distance between these two points. The distance formula is:

[tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

We know that x1 is 6, x2 is 3, y1 is -2, and y2 is 4, so we can substitute inside the equation.

[tex]\sqrt{(3 - 6)^2 + (4 - (-2))^2} \\\\\sqrt{-3^2 +6^2} \\\\\sqrt{9 +36}\\\\\sqrt{45}[/tex]

Hope this helped!

Answer:

D. The number will be less than 1 because when adding the exponents,

11 + (-14) = -3, and a number in scientific notation with a negative exponent is less than 1.

Step-by-step explanation:

The question lacks appropriate option. Find the options below;

A. The value will be greater than 1 because 4.296 x 10^11 is a very large number and multiplication always increases the size of a number.

B. The value will be greater than 1 because 4 x 2 = 8 and 8 is larger than 1.

C. The value will be less than 1 because (4.296 x 10^11) x (1.8614 x 10^-14) will be a negative number. All negative numbers are less than one.

D. The number will be less than 1 because when adding the exponents,

11 + (-14) = 3, and a number in scientific notation with a negative exponent is less than 1.

Given the expression [tex](4.296*10^{11})(1.8614*10^{-14})[/tex], to expand the expression we will apply some of the law of indices below. If a, b and m are integers

[tex]a^m*a^n = a^{a+m}[/tex]

[tex]= (4.296*10^{11})(1.8614*10^{-14})\\\\= (4.296*1.8614)(10^{11}*10^{-14}) \\\\= 7.9965744 * 10^{11}*10^{-14}\\sum \ up \ the\ power\ of\ the \ exponents\\\\= 7.9965744 *10^{11-14}\\\\= 7.9965744 *10^{-3}\\[/tex]

= 0.0079965744

Based on the result, it can be seen that the resulting value is less than 1 due to the negative power of its exponent (i.e -3). Any scientific notation having a negative exponent always returns a value that is less than 1.

Answer:

The number will be less than 1 because when adding the exponents, 11 + (negative 14) = negative 3, and a number in scientific notation with a negative exponent is less than 1.

Answer:

$5.50 + $10.50 = $16

Step-by-step explanation:

6a + 5b = $34

2a + 3b = $16

...Solving by elimination

6a + 5b = 34

-3(2a + 3b = 16)

-4b = -14

b = 14/4 0r $3.50, cost of each pound of jelly beans.

a,cost of each pound of almonds = $2.75  %2816-+3%283.50%29%29%2F2+=+2.75

...checking Using:

2a + 3b = $16

$5.50 + $10.50 = $16

Answer:

$12.72 or $25.44

Step-by-step explanation:

if he buys 2 tickets that are $12 each. half of 12 is 6 so you will have to pay 12 plus tax(6%). to find tax you would multiply 12 x .06 which would be $12.72. if it say the tickets are half off from $24 being $12 each then the answer would be $25.44. the question  dosent specify that.

Answer:

Step-by-step explanation:

The base number is 13 dollars since you must pay it before adding hourly expenses.

Every hour, you have to pay 5.50.

So, the total cost would equal:

29.50 - (13 + 5.5h) < 29.50

Think: you have 29.50. you must pay 13 dollars before using it. it costs 5.50 for each hour. your money must be less than your total.

Hope this helped :)

Answer:

[tex]x=13[/tex]

Step-by-step explanation:

The perimeter of a rectangle is given by the formula:

[tex]P=2l+2w[/tex]

Where l is the length and w is the width.

We know that the perimeter is 80. Looking at the rectangle, we can also see that the length is 2x+3 while the width is x-2. Thus, make the substitutions:

[tex]P=2l+2w\\80=2(2x+3)+2(x-2)[/tex]

Distribute:

[tex]80=4x+6+2x-4[/tex]

Combine like terms and add:

[tex]80=6x+2[/tex]

Subtract 2 from both sides:

[tex]78=6x[/tex]

Divide both side by 6:

[tex]x=13[/tex]

Thus, the value of x is 13.

Answer:

x=39

Step-by-step explanation:

Answer:

Below

Step-by-step explanation:

● (3/4)×(z+7) = y

Divide both sides by (3/4)

● (3/4)÷(3/4)×(z+7) = y÷(3/4)

● 1×(z+7) = y ÷(3/4)

● (z+7) = y ×(4/3)

● z+7 = 4y/3

Substract 7 from both sides

● z+7-7 = (4y/3)-7

● z = (4y/3)-7

This equation has infinite solutions. Every time you input a value you get a different solution.

Answer: [tex]M = 50 + 7.50 h[/tex]

Step-by-step explanation:

As per the given scenario,

Total money Christina made = (Money she made in tips) + (Per hour wage ) x (Number of hours she work in one night)   (i)

Let M is the total money she makes and h is the number of hours she works in one night.

Here, Money she made in tips = $ 50

Per hour wage = $7.50

So substitute all the values in (i), we get

[tex]M = 50 + 7.50 h[/tex]

Hence, the required function is [tex]M = 50 + 7.50 h[/tex].
