Answer: 2.25 grams
Step-by-step explanation:
In this problem, we are given the ratio of grams to weight. Since we are trying to find how many grams to give to a person with a specific weight, we can use proportions to solve.
[tex]\frac{150mg}{5kg} =\frac{x}{75kg}[/tex] [cross multiply]
[tex]11250=5x[/tex] [divide both sides by 5]
[tex]x=2250mg[/tex]
We are almost done with the problem. The problem is asking for grams, not mg, so we can use unit conversions to change that.
[tex]\frac{1000mg}{1g}=\frac{2250mg}{y}[/tex] [cross multiply]
[tex]1000y=2250[/tex] [divide both sides by 1000]
[tex]y=2.25[/tex]
Therefore, we need to give 2.25 grams.
Use partial quotients to solve 5,140 ÷ 9 = ___.
The correct answer is 571 quotient and 1 is remainder.We can solve easily by partial quotients.
What are partial quotients division?Partial quotients division is a deviation from the standard method. The divisor is multiplied with a number and the multiple obtained is deducted from the dividend. This multiple of the divisor is as close as possible to the dividend, that is less than or equal to the dividend.
Why do we use partial quotient division?Partial quotient division provides natural differentiation because we can have students solve at a level they are comfortable with and then we can challenge them to find a more efficient way. And this means using fewer steps and solve easily.
Now we solve
first 9 multiply with 500 so we get 4500. 5140-4500=640
then 9 multiply with 70 so we get 630. 640-630=10
then 9 multiply with 1 so we get 9. 10-9=1
Hence 500+70+1=571
And our remainder is 1.

Using the concept of proportion to find the value of x in the similar triangle, x is equal to 6.67
What is Similar Triangle TheoremSimilar triangle theorem states that if two triangles have corresponding angles that are equal, then the sides of the triangles are proportional to each other. This theorem can be used to solve problems involving triangles, such as finding the lengths of missing sides.
We can use the concept of ratio to find the value of x.
12 / 5 = 16 / x
Cross multiply both sides and solve for x
12 × x = 16 × 5
12x = 80
x = 80 / 12
x = 6.67

LMNP is a rectangle. Find the value of x and the length of each diagonal.
The value of x is equal to 3.
The length of diagonal LN is equal to 18 units.
The length of diagonal MP is equal to 15 units.
What is a diagonal?In Mathematics, the diagonal of a rectangle can be defined as a line segment that connects any two (2) of its non-adjacent vertices together while dividing the rectangle into two (2) equal parts.
This ultimately implies that, the length of each diagonal of a rectangle is always equal to each other. Therefore, the diagonals of any rectangle is always equal to one other.
How to determine the value of x?We would determine the value of x by equating the length of each diagonal as follows;
LN = MP
7x - 3 = 4x + 3.
7x - 4x = 3 + 3
3x = 6
x = 6/2
x = 3.
Next, we would calculate length of each diagonal as follows;
LN = 7x - 3
LN = 7(3) - 3
LN = 21 - 3
LN = 18 units.
MP = 4x + 3.
MP = 4(3) + 3.

a. How much will the patient weight in pounds?
b. How much will the patient weight in kilograms?
a) The patient weight in pounds is 234 lbs.
b) The patient weight in kilograms is 106.36 Kg.
What is Unit Conversion?The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.
Given:
The patient’s weight is 245 lbs.
Each week patient loses = 1 Kg
So, In 5 week patient loses = 5 Kg
As, 1 kg = 2.2 lbs
In 5 week patient loses = 11 lbs
a) The weight of the patient after 5 weeks = 245 lbs. - 11 lbs.
= 234 lbs.
b) The weight of the patient after 5 weeks = 234 lbs.

17. The triangles can be proven congruent by the SSS theorem.
18. The triangles cannot be proven congruent by the HL theorem, as it is not known if the triangles are right triangles.
What are the congruence theorems?The side-side-side congruence theorem, abbreviated as SSS, means that if two triangles have three equal side lengths, then the triangles are congruent.
In item 17, we have that:
Sides JK and IH are equal.Sides JI and HY are equal.Side JH is common to both triangles, hence they are equal.As the three triangles are equal, then the SSS theorem can be used to prove the congruence of the two triangles.
The HL theorem represents the hypotenuse and leg theorem, which means that if two right triangles share a hypotenuse measure along with a leg measure, then they are congruent.
Hence item 18 cannot be proven congruent by the HL theorem, as there is no information regarding whether the triangles are right triangles.

Given the circle below with secants \overline{UVW} UVW and \overline{YXW} YXW . If YW=40, YX=16YW=40,YX=16 and VW=22VW=22, find the length of \overline{UV} UV . Round to the nearest tenth if necessary.
The length of UV in the circle is given as follows:
13.2.
How to obtain the length of UV?We are given two secant segments in the circle for this problem.
For two secants, the product of the lengths of one secant segment and it's external segment equals the product of the lengths of the other secant segment and it's external segment.
Hence, from the circle given by the image presented at the end of the answer, the relation for this problem is given as follows:
(22 + 17) x 17 = (20 + UV) x 20
Hence we must simply solve the expression to obtain the length of UV, as follows:
39 x 17 = 400 + 20UV
663 = 400 + 20 UV
20 UV = 263
UV = 263/20
UV = 13.2.

Step-by-step explanation:
4x+5y=-7
-5x-3y=-1
I need help with this question since im not smart
Answer:
To solve this system of equations, you can use the method of elimination. To do this, you can add the two equations together:
4x + 5y - 5x - 3y = -7 - 1
-x + 2y = -8
Then, you can divide both sides of the equation by -1 to solve for y:
x - 2y = 8
y = (x - 8) / 2
Now that you have solved for y, you can substitute this expression back into either of the original equations to solve for x. For example, you can substitute y = (x - 8) / 2 into the first equation to get:
4x + 5((x - 8) / 2) = -7
4x + 5x - 40 = -7
9x = 33
x = 3.67
Now that you have solved for both x and y, you can find the solution to the system of equations:
x = 3.67
y = (3.67 - 8) / 2 = -2.17
So, the solution to the system of equations is x = 3.67 and y = -2.17.
A 12 ft ladder leans against the side of a house. The top of the ladder is 11 ft off the ground. Find x , the angle of elevation of the ladder. Round your answer to the nearest tenth of a degree.
The value of angle of elevation (x) is 67°
What is angle of elevation?The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.
Angle of elevation can be found by using trigonometry ratio
The height of the house is the opposite and the height of the ladder is the hypotenuse.
Therefore from trigonometry ratio;
sin x = 11/12
sin x = 0.92
x = sin^-1 (0.92)
x= 66.93°
x = 67° ( nearest degree)
Therefore the value of angle of elevation is 67°
