Answer 1
The answer to this question should be: 
1. definition of supplementary angles
2. 115
3. definition of acute angle

Supplementary angles mean that the angle will add up to 180°. In this case, that means PQR + RQS= 180° where PQR=115°
So the RQS would be 180-115=65° Acute angle is when the angle is <90° so RQS is acute angles

Answers

expand the brackets first
-3y-12=21
add 12 
-3y=33
divide by -3
y= -11
Distribute negative 3 to y and 4. After distributing you should have -3y+-12=21. 21 plus 12 equals 33. 33 divides by negative 3 equals negative 11.

The sum of two consecutive integers is 59. Write an equation that models this situation and find the values of the two integers.


A) n + 2n = 59; n = 19; 2n = 38

B) n + n + 1 = 59; n = 29; n + 1 = 28

C) n + n + 1 = 59; n = 30; n + 1 = 31

D) n + n + 1 = 59; n = 29; n + 1 = 30


Please explain your answer! : )

Answers

The equation will be:

Fred completen 10 math problems This is 40 percent of the number of math problems he has to do How many math problems must he do

Answers

he got 4 out of the 10 right how you do that you would divide the two numbers together

Answer:

15 more/ 25 problems in total

Step-by-step explanation:

During a sale at a bookstore, a customer buys one book at full price. The customer is given a 25 percent discount on a second book of equal or less value. If George buys two books that value full prices of $17 and $8, by what percent is the total cost of the two books reduced during the sale?

Answers

Amount paid for the first book is $17.

Amount paid for the second book is 0.75 x 8 = $6

Total amount paid = $17 + $6 = $23

Total full cost of the two books = $17 + $8 = $25

Amount of discount = $25 - $23 = $2

% reduction = [tex] \frac{2}{25} \times100\%=8\%[/tex]

Therefore, the percent of the total cost of the two books reduced during the sale is 8%
8% First, determine what book the discount is applied to. That will be the lower priced book, so the customer saves 25% of the cost of $8, giving 25% * $8 = 0.25 * $8 = $2 So there's a total savings of $2. Now determine what the total price of purchasing both books without the discount. That would be $17 + $8 = $25 And finally, determine what percent of $25 that $2 is, so $2 / $25 = 0.08 = 8%

You ride your bicycle at a rate of 10 mi/h. the distance d (in miles) that you ride is given by the function d=10t where t is the time in hours.

Answers

I think it is 1 hour

The function d = 10t signifies that you cover 10 miles of distance per hour.

What is the general equation of a Straight line?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

We have the following problem -

You ride your bicycle at a rate of 10 mi/h. the distance d (in miles) that you ride is given by the function d=10t.

We have the distance [d] as the function of time as -

d = 10t

The given equation id d = 10t. The slope of the line is 10. This means that you cover 10 miles of distance in 1 hour. The graph representing the function is plotted.

Therefore, the function signifies that you cover 10 miles of distance per hour.

TheValue of a stock begins at $0.05/and increase by 0.01 each month write an equation representing the value of the stock v in any months m

Answers

Because you start with $0.05, you're going to add that to whatever 0.01 is equal to after the amount of months

the equation I got was: v=0.05+(0.01m)

The linear equation can be represented as a straight line on a graph. The equation for the given case is v = 0.05 + 0.01m.

What is a Linear equation?

A linear equation is a equation that has degree as one.

To find the solution of n unknown quantities n number of equations with n number of variables are required.

Given that,

The value of stock at the beginning is $0.05,

And, its rate of increase for each month is 0.01.

Suppose the value of stock be v and the month be m,

Then, the increment in its value for any month m  is $0.01m.

Now, the equation for the value of stock v at any month m can be written by summing its initial value to its increment value obtained for each month as,

v = 0.05 + 0.01m.

Hence, the equation representing the value of the stock v in any months m is given as v = 0.05 + 0.01m.

how do you put 2.303,2.3,2.33 and 2.03 from least to greatest

Answers

you add extra zeroes until all numbers have the same quantity. in this case, 2.303 has three numbers after the decimal, so the other three number need it too. 2.300, 2.330, and 2.030. now that you have all of them looking the same now, you can tell which is least and work from there: 2.030 is the least, then 2.300, 2.303 then 2.330 is the largest.

The number can be arranged from least to greatest as 2.03<2.3<2.303<2.33.

What are decimal Numbers?

A decimal is a number with a whole and a fractional portion. Decimal numbers are between integers and indicate numerical value for a whole plus some fraction of a whole. In fraction form, we may say there is one and one-half pizzas. This is represented in decimal form as 1.5 pizzas.

Let's write the numbers to the third decimal point. Therefore, we can write the numbers as,

2.303 = 2.3032.3 = 2.3002.33 = 2.3302.03 = 2.030

Now, the numbers can be arranged as,

2.030 < 2.300 < 2.303 < 2.330

2.03 < 2.3 < 2.303 < 2.33

Hence, the number can be arranged from least to greatest as 2.03<2.3<2.303<2.33.

When the smaller of two consecutive integers is added to three three times the​ larger, the result is 23. find the integers?

Answers

consecutive integers are numbers in order, 1,2,3,4,5,6,....
if you make x the smaller number the next number will be (x+1).
x +3(x+1) = 23
x +3x +3 = 23
5x = 23 - 3
5x = 20
x = 20/5
x = 4

the smaller integer is 4 then the next is 5

The value of the integers can be obtained by solving the equation as 5 and 6 respectively.

What is a linear equation?

A linear equation in two variable has the general form as y = ax + by + c, where a, b and c are integers and a, b ≠ 0.

It can be represented as a straight line on a graph.

Suppose the smaller integer be x.

Then, the larger one is x + 1.

As per the question, the following equation can be formed as,

x + 3(x + 1) = 23

⇒ 4x + 3 = 23

⇒ x = 5

Thus, the larger integer is 5 + 1 = 6.

Hence, the integers are obtained as 5 and 6 respectively.

A counterexample showing the conclusion 'All the marbles in the bag are black' as false.

A counterexample is a scenario where the premises are true but the conclusion is false, demonstrating the invalidity of an argument. In this case, to prove invalidity, a counterexample could be a situation where there is at least one marble in the bag that is not black. For instance, if there are three black marbles and one red marble inside the bag, the selection of three black marbles is still possible, but the conclusion that all marbles are black is false.

What is the solution to 89+k=-42

Answers

subtract 89 from -42. k=-131
89+k=-42

We simplify the equation to the form, which is simple to understand
89+k=-42

We move all terms containing k to the left and all other terms to the right.
+1k=-42-89

We simplify left and right side of the equation.
+1k=-131

We divide both sides of the equation by 1 to get k.
k=-131.

What consecutive numbers have a sum of 133?

Answers

Two consecutive integers mean numbers like 2, 3 or -3, -2. Let x represent the first number. the next consecutive number will be x + 1. The equation becomes:  x + (x + 1) = 133. Solve for x: x + (x + 1) = 133 x + x + 1 = 133 2x + 1 = 133 Subtract 1 from both sides: 2x = 132 Divide both sides by 2: x = 66 x + 1 = 67. Solution: The two consecutive numbers adding up to 133 are 66 and 67.

a-b+2c=7
b+c=1
a-2b-3c=0

Answers

Equation 1)  a - b + 2c = 7
Equation 2)  b + c = 1
Equation 3)  a - 2b - 3c = 0

Subtract equation 3 from equation 1.

3)  a - 2b - 3c = 0
1)  a - b + 2c = 7

Subtract equations from one another.

-b - 5c = -7 {This will now be called equation 4)  

Then, add equation 4 into equation 2.

4)  -b - 5c = -7
2)  b + c = 1

Add.

-4c = -6

Divide both sides by -4.

c = 3/2

Plug in 3/2 for c in the 2nd equation.

2)  b + c = 1

b + (3/2) = 1

Subtract 3/2 from both sides.

b = 1 - 3/2

Simplify.

b = 1 - 1 1/2

Simplify.

b = -1/2

Plug in -1/2 for b in equation 1 so that we find the value of a.

*Remember : b = -1/2, c = 3/2

1)  a + b + 2c = 7

Plug in -1/2 for b, and plug in 3/2 for c.

a + (-1/2) + 2(3/2) = 7

Simplify.

a - 1/2 + 3 = 7

Simplify.

a - 2 1/2 = 7

Add 2 1/2 to both sides.

a = 7 + 2 1/2

Simplify.

a = 9 1/2

So, a = 9 1/2, b = -1/2, c = 3/2
