Answer:

80

Explanation:

The dogs weight rounded to the nearest ten pounds would be 80 because 76 rounded to the nearest tenth is 80. The reson why is because the 6 in the ones place is greater than 5 so you round up. Because 76 was the orignial number, and you're trying to round to the neares ten pounds, you round the 7 up because that is the number in the tenths place.

Answer:

80 pounds.

Step-by-step explanation:

The dog weighs 76 pounds.

The units value is 6 . Since we round up the tens place when the unit is equal or greater than 5 the answer is 80.

Answer:The answer would be -1

Step-by-step explanation:

First insert the -1 into the equation which would look like this -4(-1)+3 which is then multiplication which would narrow the solution down to -4+3 which a negative plus a positive is a rule called you always subtract and the number with the bigger value determines what sign you use so in this equation it would be 4 since 4 is bigger than 3 which 4-3 equals 1 so then carry the negative sign down with you and that would get you your answer of -1

To calculate how many people are registered after 4 weeks, apply the formula for exponential growth using the initial 50 users and the 15% weekly growth rate, which gives us 87 registered users after rounding to the nearest whole number.

Explanation:

The process of calculating the number of registered users after 4 weeks with a weekly growth rate of 15% involves using the formula for exponential growth. You start with the initial number of users which is 50 and multiply this by 1 plus the growth rate raised to the power of the number of time periods, which in this case is 4 weeks.

The equation to calculate the number of users after 4 weeks will be 50 × [tex](1.15)^4[/tex].

Now we calculate: 50 × [tex](1.15)^4[/tex] = 50 × 1.749 = 87.45, which when rounded to the nearest whole number is 87 registered users.

The equation to relate the number of weeks a computer programmer works to the number of hours worked is h = 40w, where h represents the total hours worked and w represents the number of weeks.

To relate the number of weeks w that a computer programmer works to the number of hours h he or she spends working, we can use a simple multiplication equation. Since we know the programmer works 40 hours per week, the relationship between hours worked and number of weeks can be represented as:

h = 40w

This equation states that the total hours worked (h) is equal to 40 times the number of weeks worked (w). For example, if the programmer works for 2 weeks, the total hours worked would be h = 40 * 2, which equals 80 hours.

The given family of facts can be completed as follows:

2 8 6 0 -4 -2 22 86.

by observing the given number pattern.

To complete the family of facts,  observe the pattern and determine the missing numbers.

Starting with the first number, 2, observe that each subsequent number is obtained by multiplying the previous number by 4 and then subtracting 2.

So, to find the next number, multiply 6 by 4 and subtract 2, giving  22.

Similarly, to find the next number after 22, we multiply 22 by 4 and subtract 2, resulting in 86.

Therefore, the completed family of facts is 2 8 6 0 -4 -2 22 86.

Answer:

175

Step-by-step explanation:

7(13+12)

distribute 7 to 13 and 12

(91+84)

175

By distributive property the expression 7(13 + 12) can be rewritten as 175.

To rewrite the expression 7(13 + 12) using the distributive property, we multiply 7 by each term inside the parentheses:

7(13 + 12) = 7 × 13 + 7 × 12

This simplifies to:

91 + 84

Adding the two terms, we get:

175

Therefore, using the distributive property, 7(13 + 12) can be rewritten as 175.

The domain of the function is the set of values for x, given as {2,3,4}. The range, which is the set of all output values for y that result when substituting each x value in the domain into the equation, is {8,6,4}.

In this problem, we are given an equation y + 2x = 12 and a domain D = {2,3,4}, which means x takes the values 2, 3, and 4. The domain of a function is all the possible values that x can take. Therefore, in this case, the domain (D) is {2,3,4}.

The range, on the other hand, includes all the corresponding output values that y takes for each x in the domain. The output is determined by plugging each value of the domain (x) into the equation and solving for y:

Hence, the range for this equation, given the domain {2,3,4}, is {8,6,4}.

Answer: The sequence is to add 12 to each new term.

Step-by-step explanation: The Best way to solve these type of questions is to quests and check. For example, one may notice 3 can be multiplied by 5 to get 15. However, 15 times 5 is 75, not 27, so the rule of multiply by 5 is not correct. Then, you may guess that the rule is to add some number to get the next. One may then notice that it is increasing by 12 each time.

The sequence provided is an arithmetic sequence where each subsequent number is 12 more than the previous one.

The sequence described in your question: 3, 15, 27, 39,... follows a rule of addition. Specifically, each subsequent number in the sequence is 12 more than the preceding number. For instance, 15 is 12 more than 3, 27 is 12 more than 15, and 39 is 12 more than 27, and so on. This sequence can be described as an arithmetic sequence with a common difference of 12.

The rule for the given sequence is that each term is obtained by adding 12 to the previous term.

3 + 12 = 15

15 + 12 = 27

27 + 12 = 39

To prove that angle 1 is equal to angle 3, we can use the given information and the properties of supplementary angles. Using substitution and algebraic manipulations, we can show that angle 1 is indeed equal to angle 3.

To prove that angle 1 is equal to angle 3, we can use the given information and the properties of supplementary angles.

Given: angle 2 = angle 4 and angle 2 and angle 3 are supplementary.

Since angle 2 and angle 4 are equal, we can substitute angle 4 with angle 2 in the given statement, giving us angle 2 = angle 2. Now, since angle 2 and angle 3 are supplementary, their sum is 180 degrees. So angle 2 + angle 3 = 180 degrees. We can rewrite this equation as angle 2 = 180 - angle 3. Now, we can substitute angle 2 in the equation with angle 4 (which is equal to angle 2), giving us angle 4 = 180 - angle 3. Rearranging this equation, we get angle 3 = 180 - angle 4. Since angle 4 = angle 2, we can substitute angle 4 with angle 2 in the equation, giving us angle 3 = 180 - angle 2. Finally, since angle 3 = 180 - angle 2, and angle 2 = angle 4 (from the given information), we can conclude that angle 1 = angle 3.

Answer:

Step-by-step explanation:

Firstly we have to distribute it and write in this form

1/4*12x-1/4*5.6=0.5*3x+0.5*0.7

3x-1.4=1.5x+0.35 ( now that we have multiplied and simplified it we will combine like terms remember whenever you move it to the other side of equal signs it turns the opposite of the sign value eg positive to negative.

subtract 0.35 from both sides leaving the equations as 3x-1.75=1.5x

now we move 3x on other side to combine with 1.5x and 3x becomes negative

-1.75=1.5x-3x

-1.75= -1.5x (divide -1.5 from both sides

-1.75/-1.5=1.5x/-1.5

1.166666666666667=x  

or 7/6 if you left the fraction as it is and didn't simplify further.

Let me know if you don't understand  or need more help .

The student's algebraic equation 1/4 (12x−5.6)=0.5(3x+0.7) simplifies to x = 1.17. This is found by distributing numbers, rearrangement of terms, and final division to solve for x.

The question is an algebraic equation that needs to be simplified and solved. First, distribute the numbers in front of the parentheses to both the terms inside. This gives:

Next, rearrange terms to bring all terms involving x to one side of the equation and constants to the other side. This gives:
