Answer: It's less than 1 because we invert the divisor and multiply.
Step-by-step explanation:
a sceintist conducts an invenstigation she mixes 4/5 ounce of one chemical with 13/20 ounce of another chemical how many ounces are in the mixture?
There are an improper fraction of 29/20 ounces or a mixed fraction of one whole number and a fraction of 1/20 ounces in the mixture.
How to calculate for the fraction of ouncesWe shall add the two fractions 4/5 and 13/20, but firstly we find the lowest common multiple (LCM) of their denominators to enable us get a single denominator before simplifying the numerator.
LCM of 2 and 20 is equal to 20
20/5 = 4 and 20/20 = 1
4/5 + 13/20 = (4×4 + 1×13)/20
4/5 + 13/20 = (16 + 13)/20
(4/5 + 13/20) ounces = 29/20 ounces
Therefore, 29/20 is an improper fraction gotten by adding the fraction of ounces, but when expressed as mixed fraction is one whole number, and a fraction 1/20 ounces in the mixture.

Find the length of TQ.
The length of the segment TQ is equal to 27 for the chord PQ intersecting another chord RS.
Chords intersecting in the interior of a circleWhen two chords are intersecting each other inside a circle, then the product of the segments of one of the chord is equal to the product of the segments of the other chord.
The chords PQ and RS are interesting each other, so;
18(2x - 5) = 14(2x + 1)
36x - 90 = 28x + 14
36x - 28x = 14 + 90
8x = 104
x = 104/8
x = 13

. Tara's meal cost $8.60. She had to pay a sales tax of 6%. Then she left a 10% tip based off the new total. What did she spend altogether?
Answer:
The answer is $10
Step-by-step explanation:
GivenTara's meal cost $8.60. She had to pay a sales tax of 6%.It means she paid tax of $8.60 which is 6%
So,
(8.60 × 6) ÷ 100
51.6/100 = $0.516
Here, The tax was $0.516
Total cost of meal
= $0.516 + $8.60 = $9.116 (including tax)
Then she left a 10% tip based on the new total.(9.116 × 10) ÷ 100 = $0.9116
Total cost (including tip)
= $9.116 + $0.9116 = $10.0276 ≈ $10
Thus, Tara spend $10 altogether.

The slope of the line made by these given coordinates is 7/6.
What is proportionality?In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one double, and both decrease in size when one drops to a tenth of its original value.
Given coordinates of a graph. Since the coordinates are proportional thus, these coordinates represent the graph of the line as shown in the figure below.
From the general formula of the slope of the line (m) = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
The slope of the line = (14-7) / (12- 6)
The slope of the line = 7/6
Equation of the line id y = 7/6x + c
Since, the line passes through the point (18, 21)
21 = 7 /6 * 18 + c
c = 0
thus, the equation of the line is 6y = 7x
therefore, the slope of the line made by these given coordinates is 7/6 and this line passes through the origin.

The measure of one angle of a right triangle is 24∘ more than the measure of the smallest angle. Find the measure of the smallest angle.
33°
Since it's a right triangle that has an immediate 90° angle, we have 90°'s left to worry about. We have two angles to worry about it, and since one angle is bigger than the other by 24°, it means that the gap between them is 24°. After doing some mental math, you get 57° + 33°. The gap between them is 24°, and they add up to 90°. Finally, since you're looking for the smaller angle in this problem, then 33° would be your answer.

So, We get;
⇒ y = 2 + x .. (ii)
Substitute the value of y from (ii) in (i), we get;
⇒ 2x + 3 (2 + x) = 16
Solve for x as;
⇒ 2x + 6 + 3x = 16
⇒ 5x = 16 - 6
⇒ 5x = 10
⇒ x = 2

Madison and her brother drove around the perimeter of their neighborhood looking for their cat. The diagram above shows the path they drove. In total, 56 kilometers did they drive. This can be solved using the concept of rectangular perimeter.
What is perimeter of a rectangle?The circumference of a form is known as its perimeter. One must sum the lengths of the all four edges of a rectangular or squares to determine its perimeter. In this instance, the rectangle's length is represented by x and its width by y. P = 2 (x+y), which is the perimeter.
The diagram is actually looks like a rectangle.
Here the length becomes = 10 km
and breadth = 18 km
The question mark here is: 18 -10 = 8km

The the area and perimeter of the shapes in terms of pi are 36pi - 72.
What is Perimeter?You should understand that the perimeter of the object is the distance round the object.
A circle's area is calculated as pi*r², so a semicircle is pi*r² / 2, and a quarter circle is pi*r² / 4.
A triangle's area is 0.5*base*height.
We have a quarter circle of radius 12, of which the area is pi*(12² / 4) = 36pi.
The area of the triangle ABC is 0.5*12*12 = 72,
This means that the shaded area is 36pi - 72.
Rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of AD is actually identical in area to the blank semicircle-shaped space to the left of BC.
