Answer:
2794 m^2
Step-by-step explanation:
Area of Triangle - Area of Circle
1/2bh - piR^2
4050 - 1256
= 2794
The approximate area of the shaded region is, 2794 m²
What is Area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
Given a right triangle with a circle cut out of it,
Area of circle = π*Radius²
Area of triangle = 1/2*base*height
Area of circle = π*20² = 1256 m²
Area of triangle = 1/2*90*90 = 4050 m²
Area of the shaded region = Area of triangle - Area of circle
Area of the shaded region = 4050 - 1256 = 2794 m²

the graph of f(x)=|x| is reflected across the x-axis, moved 2 units to the right and 7 units down. What is the function?
The transformed function after reflecting f(x)=|x| across the x-axis, moving it 2 units to the right, and 7 units down is f(x)=-|x-2|-7.
Explanation:The original function is f(x)=|x|.
When the graph of the function is reflected across the x-axis, it changes the sign of the output or y-coordinate.
Thus, the absolute value function becomes f(x)=-|x|.
When this function is moved 2 units to the right, it results in a shift in the coordinate of x within the function, thus becoming f(x)=-|x-2|.
Lastly, when the function is moved 7 units down, 7 is subtracted from the function, resulting in the final equation of f(x)=-|x-2|-7.

Rhombus
Answer:
It can be a parallelogram, a square, a rectangle and rhombus too.
Answer:
There are many special types of quadrilateral.
A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel .
A parallelogram also has the following properties:
Opposite angles are congruent;
Opposite sides are congruent;
Adjacent angles are supplementary;
The diagonals bisect each other.
A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals. On the other hand, not all quadrilaterals and parallelograms are rectangles.
A rectangle has all the properties of a parallelogram, plus the following:
The diagonals are congruent.
A rhombus is a parallelogram with four congruent sides. The plural of rhombus is rhombi . (I love that word.)
A rhombus has all the properties of a parallelogram, plus the following:
The diagonals intersect at right angles.
A square can be defined as a rhombus which is also a rectangle – in other words, a parallelogram with four congruent sides and four right angles.
A trapezoid is a quadrilateral with exactly one pair of parallel sides. (There may be some confusion about this word depending on which country you're in. In India and Britain, they say trapezium ; in America, trapezium usually means a quadrilateral with no parallel sides.)

MD writes an order for 150 mg by mouth every 6 hours for 24 hours. pharmacy dispenses you with 75 mg per 3 ml. how many ml will you administer daily?
Answer:
24ml
Step-by-step explanation:
First, calculate the amount needed in mg for each day.
The rate given for each dose is 150mg every 6 hours. Since there are 24 hours in a day, divide the number of hours in a day by how often to give the medication to get the number of doses each day.
24 hours ÷ 6 hours = 4 doses daily
The total mg each day is the number of doses daily multiplied by the amount in each dose.
4 doses daily X 150 mg = 600mg daily
Calculate how many mg of medication are in 1 ml given by the pharmacy.
75mg ÷ 3ml = 25mg/ml
Divide the mg of medication daily by the concentration the pharmacy dispenses.
600 mg daily ÷ 25mg/ml = 24ml
You will administer 24ml daily.
Check by doing these steps backwards:
24ml per day gives 600 mg of medication because there are 25mg per 1 ml. 24ml X 25mg = 600mg
Each day you need to administer 150mg X (24h ÷ 6h) of medication.
150mg X 4 = 600mg, which is the correct amount.

5x/2 + 2y = 5 .......(2)
Putting (1) into (2)
5x/2 + 2(3x/4) = 5
5x/2 + 3x/2 = 5
Multiply each term by 2
5x + 3x = 10

x = 10/8
x = 5/4
x = 1 1/4

Tina has $220 in her account. Cliff has $100 in his account. Starting in July, Tina adds $25 to her account on the first of each month, while Cliff adds $35 to his. How many dollars will they have in their accounts when the amounts are the same
Answer:
Both accounts will have $450
Step-by-step explanation:
Tina y= 25x+220
Cliff y= 35x+100
we can use substitution to solve this problem so the formatting would be:
25x+220=35x+100
subtract 25x from both sides
220=10x+100
Subtract 100 from both sides
120=10x
Divide both sides by 10
12=x
now that we have an x value we can plug it into either equation.
y=100+35(10)
y=100+350
y=450
A builder is putting floor tiles on each of the 15 kitchen floors in an apartment building. Each floor uses 40 tiles. Each floor tile costs $7.
How much does the builder spend on the floor tiles?
Answer:
$4200
Step-by-step explanation:
15 floor times 40 tiles
15 X 40 = 600 tiles
so 600 tiles times 7 dollars
600 X 7 = 4200 dollars
Final answer:
To find the total cost of floor tiles for 15 kitchen floors, multiply the total number of tiles by the cost per tile. The builder will need 600 tiles (15 floors × 40 tiles) and with each tile costing $7, the total cost comes to $4200.
Explanation:
The student is asking about the total cost of floor tiles needed for an apartment building project. To calculate this, we need to find the total number of tiles used and then multiply this by the cost per tile. There are 15 kitchen floors, with each floor using 40 tiles. Each tile costs $7.
First, let's find out how many tiles are needed in total:
Number of floors × Number of tiles per floor = Total number of tiles
15 floors × 40 tiles per floor = 600 tiles in total
Next, let's calculate the total cost:
Total number of tiles × Cost per tile = Total cost
600 tiles × $7 per tile = $4200
Therefore, the builder spends a total of $4200 on floor tiles for the 15 kitchen floors.

2 litre 450 ml mustard oil was used from a can of 5 litre in a month. How much is left? For how many months in all can it be used?
Answer:
Step-by-step explanation:
1 liter = 1000 ml....so 2 liters and 450 ml = (2* 1000) + 450) = 2450 ml
5 liters = (5 * 1000) = 5000 ml
5000 ml - 2450 ml = 2550 ml or 2 liters and 550 ml <== this is how much is left
so he used 2450 ml in 1 month....and he has 5000 ml
5000/2450 ≈ 2.04 months <=== it will be all used up
Answer:
Step-by-step explanation:
1 litre = 1000 ml
5 liter = 5 * 1000 = 5000 ml
2 liter 450 ml = 2 liter + 450 ml = 2000 ml + 450 ml = 2450 ml
Oil left = 5000 - 2450 = 2550 ml
2550 - 2450 = 100 ml
4 liter 900ml is used in two months and 100 ml will be left over

The sum of two numbers is 52. The larger number is 8 more than the smaller number. What are the numbers?
Answer:
The smaller number is 22
The larger number is 30
Step-by-step explanation:
L + S = 52
L = S + 8
Set both equations equal to L.
S + 8 = -S + 52
+S +S
2S + 8 = 52
- 8 - 8
2S = 44
S = 22
To find the larger number, plug 22 in as S into the equations.
L = 30
Final answer:
The two numbers are 22 and 30, with the smaller number being 22 and the larger one being 30 (which is 8 more than the smaller number).
Explanation:
The sum of two numbers is 52, and the larger number is 8 more than the smaller number. Let's denote the smaller number as x and the larger number as x + 8. The equation to represent their sum is:
x + (x + 8) = 52
By combining like terms, the equation simplifies to:
2x + 8 = 52
Subtract 8 from both sides of the equation to isolate the term with x:
2x = 44
Divide by 2 to solve for x:
x = 22
Now that we have the value of the smaller number, we can find the larger number:
x + 8 = 22 + 8 = 30
So, the two numbers are 22 and 30.
Suppose we want to choose 2 objects, without replacement from the objects pencil, eraser and desk
The question is about finding the number of ways to choose 2 items without replacement from a set of 3 items using combinatorics, and there are 3 different ways to do so.
The question deals with the concept of combinations in probability and combinatorics. When choosing 2 objects from a set of 3 items (a pencil, an eraser, and a desk) without replacement, we can use the combination formula C(n, k) = n! / (k!(n-k)!), where n is the total number of items and k is the number of items to choose.
In this case, we have 3 items and we want to choose 2, so we plug the values into the formula to get the number of combinations without replacement.
Using the combination formula, C(3, 2) = 3! / (2! × (3-2)!) = 3.
Therefore, there are 3 different ways to choose 2 objects from the set of a pencil, an eraser, and a desk.
X divided by 4 equals -7. What is x?
The required value of x that satisfies the equation x/4 = -7 is x = -28.
To solve for x when x divided by 4 equals -7, we can follow these steps:
Start with the equation: x/4 = -7.
To isolate x, we want to get rid of the division by 4. We can do this by multiplying both sides of the equation by 4:
(4)(x/4) = (4)(-7).
The 4 on the left side cancels out with the 4 in the denominator, leaving us with:
x = -28.
Therefore, the value of x that satisfies the equation x/4 = -7 is x = -28.

Final answer:
The value of x in the equation x divided by 4 equals -7 is -28. To find x, we multiply both sides of the equation by 4, resulting in x=-28. Substituting back into the original equation confirms the solution is correct.
Explanation:
To solve the equation x divided by 4 equals -7, we want to find the value of x. We can do this by performing the inverse operation of division, which is multiplication. So if x divided by 4 is -7, we can multiply both sides of the equation by 4 to solve for x:
x / 4 = -7
4 * (x / 4) = 4 * (-7)
x = -28
So, the value of x is -28. As a check, you can substitute -28 back into the original equation:
-28 / 4 = -7
Which simplifies to:
-7 = -7
This confirms that the solution is correct since it results in an identity, showing that the left side of the equation is equal to the right side.
