- ( 9 - ( m + a ))
= -( 9 - ( 4 + 3))
= - ( 9 - (7))
= -( 9 - 7)
= - 2
Answer:
-2
Step-by-step explanation:
Open the bracket first
-(9-(m+a))
-(9-m-a)
-9+m+a
So let's substitute the value for the m and a
-9+4+3
Using BODMAS
Addition comes before substration
So
-9+4+3
=-9+7
=-2

Find the volume of the pyramid below. Hint: The base is a right triangle, so you will need to find
the area of the base first.
112
Enter your answer as a number with no units.
Given:
Given that the height of the pyramid is 12 units.
The base of the triangle is 8 units.
The height of the triangle is 6 units.
We need to determine the volume of the pyramid.
Area of the triangle:
The area of the triangle can be determined using the formula,
[tex]A=\frac{1}{2} bh[/tex]
where b is the base of the triangle and h is the height of the triangle.
Substituting the values, we get;
[tex]A=\frac{1}{2}(8)(6)[/tex]
[tex]A=\frac{1}{2}(48)[/tex]
[tex]A=24[/tex]
Thus, the area of the triangle is 24 square units.
Volume of the pyramid:
The volume of the pyramid can be determined using the formula,
[tex]V=\frac{1}{3}AH[/tex]
where A is the area of the triangle and H is the height of the pyramid.
Substituting the values, we get;
[tex]V=\frac{1}{3}(24)(12)[/tex]
[tex]V=\frac{1}{3}(288)[/tex]
[tex]V=96[/tex]
Thus, the volume of the pyramid is 96 cubic units.

Write the ratios 20:40:60 in its simplest form?
Answer:
1:2:3
Step-by-step explanation:
The ratio 20:40:60 is simplified by dividing each number by the greatest common divisor (GCD), which is 20, giving us the simplest form of the ratio as 1:2:3.
Explanation:To write a ratio in simplest form, you have to find the greatest common divisor (GCD) of the numbers and then divide all numbers by the GCD. In the ratio 20:40:60, the GCD is 20. Therefore, when you divide each number of the ratio by the GCD you get 1:2:3. So, the ratio 20:40:60 in its simplest form is 1:2:3.

The length of a rectangle is 24 units. Can the perimeter x of the rectangle be 60 units when its width y is 11 units? (1 point)
Select one
O a. No, the rectangle cannot have x = 60 and y = 11 because x = 48 + 2y
b. No, the rectangle cannot have x = 60 and y = 11 because x = 24 + 2y
c. Yes, the rectangle can have x = 60 and y = 11 because x + y is greater than 48
d. Yes, the rectangle can have x = 60 and y = 11 because x + y is greater than 24

A rectangular garden measuring 13 meters by 15 meters is to have a gravel pathway of constant width built all around it. There is enough gravel to cover 80 square meters. Enter an inequality that represents all possible widths(w), in meters, of the pathway.
Let w represent width of the pathway.
We have been given that a rectangular garden measuring 13 meters by 15 meters is to have a gravel pathway of constant width built all around it.
Since pathway will be on all sides, so new length and width of garden with pathway would be [tex]13+2w[/tex] by [tex]15+2w[/tex].
We are also told that there is enough gravel to cover 80 square meters. This means that area f pathway should be equal to 80 square meters.
The area of the pathway will be equal to area of garden with new dimensions minus area of garden with original dimensions.
We know that area of rectangle is width times length.
[tex]\text{Area of pathway}=(15+2w)(13+2w)-15(13)[/tex]
Since we are asked to write an inequality that represents all possible widths(w), in meters, of the pathway, so area of pathway should be less than or equal to 80 square meters.
[tex](15+2w)(13+2w)-15(13)\leq 80[/tex]
Therefore, our required inequality would be [tex](15+2w)(13+2w)-15(13)\leq 80[/tex].

A right triangle has sides of length 3, 4, and x. Find x if it is a LEG.
Work Shown:
a = x, b = 3, c = 4
a^2 + b^2 = c^2 ... pythagorean theorem
x^2 + (3)^2 = (4)^2
x^2 + 9 = 16
x^2 = 16 - 9
x^2 = 7
x = sqrt(7)
x = 2.64575131106459
x = 2.6
In a right triangle with one leg of length 3, the other leg of length 4, and the hypotenuse of length x, the Pythagorean theorem formula (3² + 4² = x²) gives the length of x as √25, or 5 units.
Explanation:In Mathematics, a right triangle has one angle that is a right angle (90 degrees). In these triangles, the Pythagorean theorem applies, which says that the square of the length of the longest side (hypotenuse) is equal to the sum of squares of the other two sides (legs).
If x is a leg of the triangle, then its length can be found by rearranging the Pythagorean theorem formula. If the length of one leg is 3, the other is 4, and the length of the hypotenuse is x, then the equation is: 3² + 4² = x².
That simplifies to 9 + 16 = x², and further to x² = 25. Taking the square root of both sides gives us the length of x as 5 units.

Answer:

Step-by-step explanation:
The name of the chart is "Participants PER race"
That means they tall you how many people did the race now all you gotta do is, Count up the numbers more than 61- So look at the 6 in the "stem" portion
it has 67, 67 they are both more than 61
Then look at the next "stem" number- 7
that has 74 which is more than 61 but less than 85
Then we look at the 8 in the "stem" it has three numbers- 84, 86, 89
but 86 and 89 are more than 85 so 84 is the only one which will go through
So the numbers are: 67, 67, 74, and 84
Thus 4 participants

3y+6+4y−7=−8
Solve for y
The solution to the equation 3y + 6 + 4y - 7 = -8 is y = -1.
We have,
To solve the equation 3y + 6 + 4y - 7 = -8 for y, we can combine like terms and isolate the variable.
Combining like terms on the left side of the equation, we have:
3y + 4y + 6 - 7 = -8
Simplifying further:
7y - 1 = -8
Next, let's isolate the y-term by moving the constant term to the other side of the equation:
7y = -8 + 1
Simplifying:
7y = -7
Finally, divide both sides of the equation by 7 to solve for y:
y = -7/7
Simplifying the fraction:
y = -1
Therefore,
The solution to the equation 3y + 6 + 4y - 7 = -8 is y = -1.

Given a parallelogram with points

We want to find the perimeter, perimeter is the total sum of the lengths
So, we need to find the length of the sides using distance between two points
D = √(x2-x1)² + (y2-y1)²
So, applying this
WX = √(0-4)²+(-1-0)² = √(16 + 1) = √17
XY = √(4-3)² + (0--2)² = √(1+4) = √5
Since the opposite sides of a parallelogram are equal, we don't need to find the other length
Then,
Perimeter = 2(WX + XY)
Perimeter = 2(√17 + √5)
Perimeter = 2√17 + 2√5
