Simplify -15- |-7.5|
Answers
Answer:
-22.5
Step-by-step explanation:
-15- |-7.5|
after taking the absolute value off, -7.5 would become positive 7.5. But then the negative outside the absolute value makes it negative again.
-15-7.5
=-22.5
The simplified expression -15 - |-7.5| is equal to -22.5.
To simplify the expression -15 - |-7.5|, we'll follow these steps:
Evaluate the absolute value: |-7.5|.
The absolute value of a number is its distance from zero on the number line. In this case, |-7.5| is equal to 7.5 because 7.5 units away from zero.
Substitute the absolute value into the expression:
-15 - 7.5.
Perform the subtraction:
-15 - 7.5 = -22.5.
Therefore, the simplified expression -15 - |-7.5| is equal to -22.5.

whats the surface area?
Answers
Answer:
1108 in²
Step-by-step explanation:
You want the total surface area of the pentagonal prism shown.
Base areaThe area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...
A = LW +1/2bh
A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches
Lateral areaThe lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.
LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches
Total areaThe total surface area of the figure is the sum of the two base areas and the lateral area:
SA = 2(114 in²) +880 in² = 1108 in²
The surface area of the composite figure is 1108 in².

what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answers
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.

Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

Q1) 80% of a dog's mass is equal to 24% of the mass of a lion. If the mass of the lion is 105 kg more than the mass of the dog, find the total mass of the dog and the lion.
Answers
We are given that 80% of the dog's mass is equal to 24% of the lion's mass. Mathematically, this can be expressed as:
0.80D = 0.24L
We are also given that the mass of the lion is 105 kg more than the mass of the dog:
L = D + 105
We can use these two equations to find the values of D and L.
Substituting the value of L from the second equation into the first equation:
0.80D = 0.24(D + 105)
Now, let's solve for D:
0.80D = 0.24D + 0.24(105)
0.80D - 0.24D = 25.2
0.56D = 25.2
D = 25.2 / 0.56
D ≈ 45
Now that we have the value of D, we can find the value of L by substituting it back into the second equation:
L = 45 + 105
L = 150
Therefore, the total mass of the dog and the lion is:
D + L = 45 + 150 = 195 kg
So, the total mass of the dog and the lion is 195 kg.

A submarine submerges from the surface of the sea at the rate of 10 m/min. How long will it take to reach 300 m below the sea level
Answers
Answer:
answer is 300m/30min

300\10=30
Given the speed of the submarine, the total time it will take to cover the the given distance is 30 minutes.
How long will it take the submarine to reach 300 m below the sea level?Using the expression Time = distance / speed.
Given that;
Speed = 10m/minDistance = 300mTime = ?Time = distance / speed
Time = 300m / 10m/min
Time = 30 minutes

the cost of endless chicken wings and sauce at restaurant x is $10. The cost of chicken wings at restaurant z is $0.50 per wing plus a one-time $1.50 charge for sauce. the total cost, c, of n chicken wings can be represented by a system of equations.
a.) write the system of equations that could be used to find out the cost of n chicken wings at each restaurant.
b.) graph the system of equations
c.) when will the total cost of the same number of chicken wings be the same at both restaurants? Explain.
Answers
Answer:
.27w+3=18
.27w=15
w=15/.27
w=55.5r
Sadly, there is no such number of wings. You can’t order fractional wings, only whole numbers of them. So you can either order 55 wings, paying $14.85 plus the $3 sauce charge, a total of $17.85, less than the $18 charge at restaurant W… or you can order 56 wings, paying $15.12 plus the $3 sauce charge, a total of $18.12, more than the $18 charge at restaurant W.
Even if you skip the sauce, you still end up picking either 66 (coming up short) or 67 wings (paying more)
The total cost, c, of n chicken wings can be represented by a system of equations.:c = 10; c = 0.50n + 1.50. The graph has been attached below. The total cost of 17 chicken wings is the same at both restaurants.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
a.) The cost of n chicken wings and sauce at restaurant x is represented by the equation: c = 10
The cost of n chicken wings and sauce at restaurant x is represented by the equation: c = 0.50n + 1.50
The system of equations is:
c = 10
c = 0.50n + 1.50
b.) To graph the system of equations, we can plot the two equations on the same coordinate plane. The x-axis represents the number of chicken wings, and the y-axis represents the cost in dollars.
The graph has been attached below.
For the equation c = 10, this represents a horizontal line at y = 10.
For the equation c = 0.50n + 1.50, this is a line that has a slope of 0.50 and y-intercept of 1.50.
c.) The total cost of the same number of chicken wings will be the same at both restaurants when the lines representing the cost at each restaurant intersect. This occurs at the point where the lines have the same y-value, which is the cost.
To find the point of intersection, we can solve the system of equations by setting the two equations equal to each other and solving for n, the number of chicken wings.
c = 10
c = 0.50n + 1.50
Substituting the first equation into the second equation, we get:
10 = 0.50n + 1.50
Subtracting 1.50 from both sides, we get:
8.50 = 0.50n
Dividing both sides by 0.50, we get:
n = 17
This means that the total cost of 17 chicken wings is the same at both restaurants. At any number of chicken wings less than 17, the cost at restaurant x will be less than the cost at restaurant z. At any number of chicken wings greater than 17, the cost at restaurant z will be less than the cost at restaurant x.
