The three solutions of the inequalities are x < 0 , x < 0.8 , x< -2
What are inequalities?Inequalities are defined as mathematical expressions in which both sides are not made equal to each other.
Given the inequalities;
x-0.8 <0-5x<10Let's solve for the value of x
x - 0.8 < 0
Make 'x' the subject
x < 0 + 0. 8
x < 0. 8
-5x < 10
Make 'x' the subject by dividing both sides by - 5
-5x/ 5 < 10/ -5
x < -2
Thus, the three solutions of the inequalities are x < 0 , x < 0.8 , x< -2

Find sin 0 and tan 0 if cos 0= 5/13, assuming that
[tex]0 \leqslant 0 < \ \frac{\pi}{2} [/tex]
sin( θ) = 12/13 and tan( θ) = 12/5.
sin θ, cos θ, tan θ are the three important trigonometry functions.
If θ lies in the first quadrant that is 0 ≤ θ < π/2, then the value of all trigonometry functions is positive.
The three most significant trigonometry functions are sin θ, cos θ, and tan θ.
If θ is located in the first quadrant, which is equal to θ/2, then all trigonometric functions have positive values.
The three important trigonometry identities are:
sin²( θ ) + cos²( θ ) = 1
1 + tan²( θ ) = sec²( θ )
1 + cot²( θ ) = csc²( θ )
Now we have,
cos θ = 5/13
Then,
sin²( θ ) + cos²( θ ) = 1
sin²( θ ) + ( 5/13 )² = 1
sin²( θ ) + 25/169 = 1
sin²( θ ) = 1 - 25/169
sin²( θ ) = ( 169 - 25)/ 169
sin²( θ ) = 144/ 169
sin( θ ) = √( 144/ 169 )
sin( θ ) = ± 12/13
Since, 0 ≤ θ < π/2
sin( θ ) = 12/13
Now we know,
tan(θ) = sin(θ) / cos(θ)
tan(θ) = ( 12/13 ) / ( 5/13)
tan(θ) = 12/5

(a) A cylindrical glass jar whose height is 7 inches and whose diameter is 4 inches. Find the
capacity of the jar.
The volume of the glass jar is 87.96 cubic inch.
What is volume?Volume is a unit used to express how much three-dimensional space is occupied. It is usually represented quantitatively in different imperial measures, such as the gallon, quart, and cubic inch, or in SI-derived units like the cubic meter and liter. The cubic concept of length and volume are connected.
Volume is a three-dimensional measurement that's used to gauge a solid shape's capacity. It implies that the volume of a closed form determines how much space it may occupy in three dimensions.
The capacity of the jar is calculated as
Volume of cylinder = [tex]\pi r^{2}h[/tex] = [tex]\pi (2^{2})7[/tex] = [tex]28\pi[/tex] = 87.96 cubic inch.
Hence the capacity of the glass jar is 87.96 cubic inches.

A garden table and a bench cost $863 combined. The garden table costs $87 less than the bench. What is the cost of the bench?
Answer:
The bench costs $388.
Step-by-step explanation:
Let the cost of the bench be x
The cost of the garden table = x + 87
x + (x + 87) = 863
2x + 87 = 863
2x = 776
x = 388
The bench costs $388 and the garden table costs 388 + 87 = $475
475 + 388 = 863

The depth of a local river averages 16 ft, which is represented as |−16|. In January, it measured 4 ft deep, or |−4|, and in July, it was 18 ft, or |−18|. What is the difference between depths in January and July?
22 feet
14 feet
10 feet
2 feet
The difference between depths in January and July is 14 feets
The depth of a local river averages 16 ft., which is represented as |−16|.
In January, The depth of a local river measured 4 ft. deep, or |−4|
in July, The depth of a local river 18 ft., or |−18|
The average depth of a local river is measured as -16 because it is below the ground level and hence measured or plotted on -y axis
the difference between depths in January and July can be measured as
|−18| - |−4|
This is absolute sign which means every number inside this sign should be treated as positive

How much of the circle is shaded? Write your answer as a fraction in simplest form.
Answer:
5/18
Step-by-step explanation:
1/2 × 9/9 = 9/18
2/9 × 2/2 = 4/18
This means we have 9/18 and 4/18 left in the circle. Because these fractions have a common denominator, we can now subtract them from the whole to find the shaded portion:
18/18 - 9/18 - 4/18 = 5/18
The shaded portion is 5/18, which is already in simplest form.

The final answer in scientific notation with the correct number of significant digits, and label with the correct units is 4.1 * 10^6 square ft
Part A: If half of the field is used to grow crops, what is the area of the portion of the field that has crops growing?The dimensions of the field are given as
Length = 3.3 * 10^3
Width = 2.5 * 10^3
From the question, we have
Half of the field is used to grow crops
This means that the area of the portion of the field that has crops growing is
Area = 1/2 * Length * Width
So, we have
Area = 1/2 * 3.3 * 10^3 * 2.5 * 10^3
Evaluate the product
Area = 4.125 * 10^6
Part B: Write the final answer in scientific notation with the correct number of significant digits, and label with the correct units.In (a), we have

Given, the sides of the rectangle are:
length = 2x ₊ 2 and
breadth = 3x ₋ 2
perimeter of the rectangle = 48 units
2(l ₊ b) = 48

Active dry yeast and bread machine yeast were not available in stores during the coronavirus pandemic. Fleischmann’s attempted to staff two shifts to produce enough active dry yeast to put some yeast back on the market. If the first shift produced 1½ times as many yeast packets as the second shift, and 5,600 packets of yeast were produced during the month, how many packets of yeast were produced on each shift
Based on the rate of the production of yeast packets by the two shifts of Fleischmann’s, the packets produced in each shift were:
First shift - 3,360 packets Second shift - 2,240 packets What number of yeast packets were produced?Assuming that the number of yeast packets produced in the second shift is x, the number produced in the first shift would be:
= 1½ × x
= 1.5x
The number of yeast packets in the second shift is:
x + 1.5x = 5,600
2.5x = 5,600
x = 5,600 / 2.5
