write additive and multiplicative inverse of19/-6 and-2/3
Additive inverse of 19/-6 is 19/6
Additive inverse of -2/3 is 2/3
Multiplicative inverse of 19/-6 is -6/19
Multiplicative inverse of -2/3 is 3/-2 (also written as -3/2)
Step-by-step explanation:
(a) The additive inverse of a number is that number that when added to it gives 0.
For example, the additive inverse of x is -x.
This is because adding -x to x gives 0. i.e
x + (-x) = 0
In other words, the additive inverse of a number is the negative of that number.
Given:
(i) 19/-6
The additive inverse of 19/-6 is the negative of 19/-6 which is -(19/-6).
-(19/-6) then gives 19/6
Therefore, the additive inverse of 19/-6 is 19/6
(ii) -2/3
The additive inverse of -2/3 is the negative of -2/3 which is -(-2/3).
-(-2/3) then gives 2/3
Therefore, the additive inverse of -2/3 is 2/3
(b) The multiplicative inverse of a number is that number that when multiplied by it gives 1.
For example, the multiplicative inverse of y is 1/y.
This is because multiplying y by 1/y gives 1. i.e
y x (1/y) = 1
In other words, the multiplicative inverse of a number is the reciprocal of that number.
Given:
(i) 19/-6
The multiplicative inverse of 19/-6 is the reciprocal of 19/-6 which is 1/(19/-6).
1 / (19/-6) then gives -6/19
This is found by just swapping the numerator(19) and the denominator(-6)
Therefore, the multiplicative inverse of 19/-6 is -6/19
(ii) -2/3
The multiplicative inverse of -2/3 is the reciprocal of -2/3 which is 1/(-2/3).
1 / ( -2/3) then gives 3/-2
This is found by just swapping the numerator(-2) and the denominator(3)
Therefore, the multiplicative inverse of -2/3 is 3/-2 (also written as -3/2).
The ratio of cattle to horses on the ranch was 12 to 3. The combined number of cattle and horses was 960. How many horses are on the ranch?
Answer: There are 192 horses in the ranch
Step-by-step explanation:
The combined number of cattle and horses = 960.
Ratio of cattle to horses =12 :3
Total ratio =12+3=15
Number of horses on the ranch = ratio of horse / Total ratio x total number of horses and cattle
3/15 x 960 = 192
Therefore there are 192 horses in the ranch

Tyler and Bethany have 240 feet of fencing with which to build a garden. Tyler wants the garden to be in the shape of a square, while Bethany wants it to be rectangular with a length of 50 feet and a width of 70 feet. Which design would give the maximum area for the garden? Explain.
Bethany’s design would give the larger garden because the area would be 3,500 ft2.
Tyler’s design would give the larger garden because the area would be 3,600 ft2.
Bethany’s and Tyler’s designs would give a garden with the same area.
Bethany’s and Tyler’s designs are not possible with the given amount of fencing.
Answer:
Step-by-step explanation:
Tyler's square is going to be 60 feet on each side. That is 3600 square feet.
Bethany can build a rectangle to her shape. It will be 240 feet of fencing. But it will give only 3500 square feet.
A is wrong. A square maximizes the area.
B is correct.
C The areas are not the same. C is wrong.
D is wrong. Both fence proposals work.
Answer:
B is correct
Explanation:
Tyler's square is going to be 60 feet on each side. That is 3600 square feet.
Bethany can build a rectangle to her shape. It will be 240 feet of fencing. But it will give only 3500 square feet.

A right rectangular prism has a base with an area of `25\ \frac{1}{2}`square feet and a volume of 153 cubic feet. What is the height, in feet, of the right rectangular prism?
Answer:
Height = 6 feet
Step-by-step explanation:
Given the following data;
Base area = 25½ ft²
Volume = 153 ft³
To find the height of the right rectangular prism;
Mathematically, the volume of a right rectangular prism is given by the formula;
Volume = base area * height
Substituting into the formula, we have;
153 = 25½ * height
153 = 51/2 * height
Cross-multiplying, we have;
306 = 51 * height
Height = 306/51
Height = 6 feet
Right rectangular prism is also called cuboid. The height of the right rectangular prism considered is evaluated as of 6 ft
How to find the volume of a right rectangular prism?Suppose that the right rectangular prism in consideration be having its dimensions as 'a' units, 'b' units, and 'c' units, then its volume is given as:
[tex]V = a\times b \times c \: \: unit^3[/tex]
For this case, we're provided that:
Base area of the right rectangular prism = [tex]25\dfrac{1}{2} = 25 + 0.5 = 25.5 \: \rm ft^2[/tex]Volume of the right rectangular prism = [tex]153\: \rm ft^3[/tex]Let the length and width of the prism be L ft and W ft
Let the heigth of the prism be H ft
Then, we get:
Area of base = [tex]L \times W = 25.5 \: \rm ft^2[/tex] (since base is a rectangle with length L and width W).Volume of prism = [tex]V = H \times L \times W = H \times 25.5 = 153 \: \rm ft^3[/tex]Thus, we get:
[tex]H \times 25.5= 153\\\\\text{Dividing both the sides by 25.5}\\\\H = \dfrac{153}{25.5} = 6 \: \rm ft[/tex]
Thus, the height of the right rectangular prism considered is evaluated as of 6 ft.

Find the measure of the are or angle indicated. Assume that lines which appear tanget are tangents
Given:
On a circle, UT and UV are two tangent
Measure of arc VT = 125 degrees.
To find:
The measure of angle TUV.
Solution:
Intersecting tangents theorem: According to this theorem, if two tangent are drawn to the circle then the measure of angle on the intersection is half of the difference of intercepted major arc and minor arc.
We know that the measure of complete arc of a circle is 360 degrees. So,
[tex]\text{Major arc}(VT)=360^\circ -\text{Minor arc}(VT)[/tex]
[tex]\text{Major arc}(VT)=360^\circ -125^\circ[/tex]
[tex]\text{Major arc}(VT)=235^\circ[/tex]
Using Intersecting tangents theorem, we get
[tex]m\angle TUV =\dfrac{1}{2}(\text{Major arc}(VT)-\text{Minor arc}(VT))[/tex]
[tex]m\angle TUV =\dfrac{1}{2}(235^\circ -125^\circ )[/tex]
[tex]m\angle TUV =\dfrac{1}{2}(110^\circ )[/tex]
[tex]m\angle TUV =55^\circ[/tex]
Therefore, the measure of angle TUV is 55 degrees.

Answer:

Step-by-step explanation:
This is because, the factor 3 in from of the elements in parentheses on the left hand side is less than the factor 6 in from of the elements in parentheses on the right hand side. Thus, the product on the left hand side is less than the product on the right hand side, since the sum in parentheses on both sides are the same.

What is the probability that a customer ordered

drink?
Rounded to the nearest percent, [? ]%
Enter
Copyright
Answer: p=25%
Step-by-step explanation:We have a sample of 100 clients.
To find the probability that a randomly selected customer chooses a cold drink, we must first count how many people in the sample chose cold drinks.
The table shows that cold drinks were
8 small, 12 medium and 5 large.
Then the number of cold drinks was:
The probability that the customer ordered a small given that he or she ordered a hot drink is 67%.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given a table which shows the number of orders of coffee by first 100 customers.
Out of it,
Total number of orders which are hot = 5 + 48 + 22 = 75
Number of orders which are small out of the total hot drinks = 5
Probability = 5/75 = 0.6667 = 66.67% ≈ 67%
Hence the required percent is 67%.

Find the surface area and volume of the prisim it has 5cm 12cm 13cm and 28cm The surface area of the prism is (blank)cm2 The volume of the prism is (blank)cm3 pls help i need this quick!
Answer:
A = 1124 cm²
V = 840 cm³
Step-by-step explanation:
Assuming the prism is a triangular prism,
Applying,
V = 1/2bhL.................. Equation 1
Where V = volume of the prism, L= lenght of the prism, b = base of the triangle, h = height of the triangle
From the question,
Given: L = 28 cm, 12 cm, h = 5 cm
Substitute these values into equation 1
V = (5×12×28)/2
V = 840 cm³
Surface area (A) = bh+(a+b+c)L
A = (5×12)+(13+13+12)28
A = 60+1064
A = 1124 cm²
