-10+ (-15)=??? Plzzz help me show work plz <3

Answers

Answer 1
The equation is -10+(-15). So you take -15 out of the parentheses and you get -10-15 because if you add a negative number then it's just subtracting. So -10-15 is -25. Because 15 less than -10 is -25.
Answer 2
The answer would be 5 (positive) because a negative and a negative = a positive

how to solve this kind of question?

Answers

96 degrees.

x is the opposite angle to one of the interior angles in the quadrilateral. The interior angles to the quadrilateral are.
1. For the pentagon 180-108 = 72 degrees
2. For the hexagon 180-120 = 60 degrees
3. For the angle with both hexagon and pentagon = 360 - 180 - 120 = 132
4. For the opposite angle to x, since it's the last of the 4 angles in the quadrilateral  will be 360 - 72 - 60 - 132 = 96 degrees

And since x is opposite this 4th angle, it too will have the value 96 degrees.

96 degrees Looking at the diagram, you have a regular pentagon on top and a regular hexagon on the bottom. Towards the right of those figures, a side is extended to create an irregularly shaped quadrilateral. And you want to fine the value of the congruent angle to the furthermost interior angle. So let's start. Each interior angle of the pentagon has a value of 108. The supplementary angle will be 180 - 108 = 72. So one of the interior angles of the quadrilateral will be 72. From the hexagon, each interior angle is 120 degrees. So the supplementary angle will be 180-120 = 60 degrees. That's another interior angle of the quadrilateral. The 3rd interior angle of the quadrilateral will be 360-108-120 = 132 degrees. So we now have 3 of the interior angles which are 72, 60, and 132. Since all the interior angles will add up to 360, the 4th angle will be 360 - 72 - 60 - 132 = 96 degrees. And since x is the opposite (or congruent) angle to this 4th interior angle, it too has the value of 96 degrees.

the walls of a square room need painting.Each of the four walls is 12 ft wide by 8.5 feet tall.One gallon of paint covers 75 ft.How many gallons will you need?

Answers

The walls of a room need painting. Each of the four walls is 12 ft wide by 8.5 feet tall.

We know that, Area = length [tex]\times[/tex] width.

So, the area of one wall = 8.5 ft [tex]\times[/tex] 12 ft = 102 square feet

Thus, the area of 4 walls = 4 [tex]\times[/tex] 102 = 408 square feet

One gallon of paint covers 75 square feet. We need to find how many gallons of paint will cover 408 square feet.

So, the amount of gallons of paint needed = 408[tex]\div[/tex]75

= 5.44 gallons

So, 5.44 gallons are needed to cover 408 square feet.

Final answer:

To find the number of gallons of paint needed to paint the walls of a square room, calculate the total area of all four walls and divide it by the coverage of one gallon of paint.

Explanation:

To find the total area of all four walls, we need to calculate the area of one wall and then multiply it by four. The area of one wall is the product of its width and height, which is 12 ft x 8.5 ft = 102 ft².

So, the total area of all four walls is 102 ft² x 4 = 408 ft².

Since one gallon of paint covers 75 ft², we divide the total area of all four walls (408 ft²) by the coverage of one gallon of paint (75 ft²) to find the number of gallons needed: 408 ft² ÷ 75 ft² = 5.44 gallons.

Therefore, you will need approximately 5.44 gallons of paint to paint the walls of the square room.

The minimum value of g(x) is greater than the maximum value of f(x).

Thank you! :)

Answers

The statement that is true about the graph is The maximum value of g(x) is greater than the minimum value of f(x).

1. "The maximum value of g(x) is greater than the minimum value of f(x)": This is true because the maximum value of g(x) is -10, which is greater than the minimum value of f(x) (which we don't know, but it cannot be lower than -10 based on the given data).

2. "The minimum value of g(x) is less than the maximum value of f(x)": This is true based on the given data, as the minimum value of g(x) is -1, which is less than the maximum value of f(x) (which we don't know, but it cannot be higher than -1 based on the given data).

3. "The minimum value of g(x) is greater than the maximum value of f(x)": This is false based on the given data. The minimum value of g(x) is -1, which is less than the maximum value of f(x) (which we don't know).

4. "The maximum value of g(x) is less than the minimum value of f(x)": This is false based on the given data. The maximum value of g(x) is -10, which is less than the minimum value of f(x) (which we don't know, but it cannot be lower than -10 based on the given data).

The greatest value of g(x) is -1 (the higher number for the g(x) entry in the table), and the minimum value of f(x) is -3 (the lower y/f(x) you may point on the graph). As a result, the maximum value of g(x) exceeds the minimum value of f(x).

5(25 mm ÷ 4 m) 
5 × 6.25 = 31.25 mm

The length of the blueprint would be 31.25 millimeters. 

I hope this helps!

Answer:

31.25 mm

Step-by-step explanation:

Use a proportion.

25 mm is to 4 m as x mm is to 5 m

25/4 = x/5

4x = 125

x = 125/4

x = 31.25

What is the function rule for the line?

A. f(x) = 3/2x - 2
B. f(x) = -2/3x - 2
C. f(x) = -3/2x - 2
D. f(x) = -3/2x + 2

Answers

(-3,0) and (0,-2)
slope = (-2 - 0)/(0 + 3) = -2/3
b = -2
so equation
y = -2/3(x) - 2

answer
B. f(x) = -2/3(x) - 2
Let's find the slope-intercept equation of this line.  You can read off the y-intercept immediately; it's the place where x= 0 and the line crosses the y-axis.  Here that intercept is b=-2.

The coordinates of that point are (0,-2).

Now let's find the slope of the line.  Starting at (0,-2) move to the left 3 units (because -3 is the x-coordinate of the intersection of the line with the x-axis).  From (0,-2), how far UP along the y-axis to the x-axis is it?

slope = rise / run.  In this case, starting from (0,-2), and moving 3 units to the left, we get "run" = -3.  Starting from (0,-2) and moving straight up to the x-axis, we get "rise" = 2.

The slope is then m = rise / run   =  2/-3, or    m = -2/3.

Thus, the equation of this line is y = mx + b, or   y = (-2/3)x - 2.

Answers

4b + 2 is your answer just to help you out if you use cymath you can easily get your answer like i did 

Final answer:

Combine like terms by adding or subtracting the coefficients of terms with the same variable and combining constants. The simplified expression is 4b + 2, so the coefficients that go in the boxes are 4 and 2.

Explanation:

To simplify the expression by combining like terms, follow the process of identifying and adding/subtracting like terms. The expression 7b + 4 - 3b - 2 contains both variable terms (containing 'b') and constant terms (just numbers).

Combine like terms:

Combine variable terms: 7b - 3b = 4b.

Combine constant terms: 4 - 2 = 2.

After combining like terms, the simplified expression is 4b + 2.

Therefore, the numbers that go in the boxes are 4 for the coefficient of 'b' and 2 for the constant term.

At 9:00 am linda leave work on a trip, sets her cruise control at 60mph. At 9:30 am, Bruce notices she left her briefcase and gets on the free way driving 90mph. At what time will Bruce catch up with Linda?

Answers

60×1.5=90 1.5 hours equals 10:30
9:30 + one hour equals 10:30 and 90 miles away
In conclusion they will meet at 10:30
Final answer:

Bruce will catch up with Linda at 9:48 am.

Explanation:

To find the time at which Bruce catches up with Linda, we need to determine the time it takes for Bruce to cover the same distance that Linda has already covered.

Since Linda starts her trip at 9:00 am and Bruce starts 30 minutes later at 9:30 am, Linda has a head start of 30 minutes or 0.5 hours.

In that 0.5 hours, Linda travels a distance of:

Distance traveled by Linda = Speed * Time
Distance traveled by Linda = 60 mph * 0.5 hours
Distance traveled by Linda = 30 miles

Now, Bruce needs to catch up with that distance of 30 miles. Let's find the time it takes for Bruce to cover that distance at his speed of 90 mph:

Time taken by Bruce = Distance / Speed
Time taken by Bruce = 30 miles / 90 mph
Time taken by Bruce = 0.33 hours

Since Bruce started at 9:30 am, he will catch up with Linda at:

Catch up time = Start time + Time taken by Bruce
Catch up time = 9:30 am + 0.33 hours
Catch up time = 9:48 am

Let us take  hours worked as x and Amount paid as y.

In the given functions

y = 15.4x ...(1)

y = 15.2x ...(2)

y = 16.4x ...(3)

y = 14.9x....(4)

We need to check which satisfies the relationship between x and y.

If x=2 then we need to get 30.4

So let us put x=2 in equation 1.

y=15.4×2

Now let us check with second function.

y=15.2×2

y=30.4
