Answer:
31
Step-by-step explanation:
The solution of expression 20 divided by cos70° is,
⇒ 20 divided by cos70° = 58.82
We have to given that,
A number 20 divided by cos70°.
We can simplify the expression as,
20 divided by cos70°
⇒ 20 ÷ cos 70°
⇒ 20 / cos 70°
⇒ 20 / 0.34
⇒ 20 x 100 / 0.34x100
⇒ 2000/34
⇒ 58.82
Therefore, The solution of expression 20 divided by cos70° is,

The dimensions of a rectangular garden are 15 yards by 20 yards. A sidewalk, one yard wide, is to be built around the outside of the garden. What will be the area of the sidewalk?
Answer:
74 square yards
Step-by-step explanation:
Area of two-dimensional shapes:Area of rectangular garden:
l = 20 yds
w = 15 yds
Area of the rectangular garden = l *w
= 20 * 15
= 300 square yards.
Area of the outer rectangle (rectangular garden and the sidewalk):
length = 20 + 1 + 1 = 22 yds
width = 15 + 1 + 1 = 17 yds
Area of outer rectangle = 22 * 17
= 374 square yards
To find the area of the sidewalk, subtract the area of rectangular garden from the outer rectangle.
Area of the sidewalk = area of outer rectangle - area of sidewalk
= 374 - 300
= 74 square yards

The five steps to resolving inequalities are as follows?
When addressing an inequality, we can:
Equal numbers are added to both sides.Take the same amount away from both sides.Add the same positive number to both sides.Subtract the same positive value from both sides.Reverse the sign and multiply both sides by the same negative value.Isolate the variable on one side of the inequality and place all other constants on the other. To achieve this, alter the inequality by performing opposing procedures. First, multiply each side by two to isolate the x. Any action you take toward one side must also be taken toward the other.
C) If x = -1,
|x| - 2 ≤ -3

Answer:
both a and b
Step-by-step explanation:
It is because in the elimination method it does not matter whether you eliminate x or y so if you use option a which multiplies -2 by 1st equation so it will become:
-4x+6y=40
4x+6y=8
so the -4x and 4x cancels and a is a valid option.
If you use the b which multiplies the second with 3 it becomes:
2x-3y=-10
4x+3y=24
so -3y and 3y cancel which also makes this a valid option.
Answer: both a and b
a survey has an error in departure (ed) of 0.35 ft, and error in latitude (el) of 0.82 ft. the total distance covered i the survey is 684.5 ft. compute the precision (choose the answer that is closest)
The correct value for the precision is found to be 0.0013 for the survey.
What is called the precision in surveying?Our measurement processes take into account accuracy and precision. How precisely a measurement or observation compares to a predetermined value or benchmark defines its accuracy. Contrarily, precision is the degree to which a measurement is repeatable precisely without reference to any specific significance or standard.The formula for finding the precision is-
Precision = E(closure)/ Perimeter
E(closure) = √(ed)² + (el)²
Where,
error in latitude (el) = 0.82 ft
error in departure (ed) = 0.35 ft.
Perimeter = 684.5 ft.
Find the E(closure)
E(closure) = √(0.82)² + (0.35)²
E(closure) = 0.89
Precision = 0.89/684.5
Precision = 0.0013
Thus, the correct value for the precision is found to be 0.0013 for the survey.

Which equation represents a line which is perpendicular to the line y=-4x-5?
A. x+4y=-32
B.4x+y=3
C.4x−y=−4
D.4y−x=4
Answer:
D.4y−x=4
Step-by-step explanation:
Perpendicual lines have a slope that is the negative inverse of the referenced line. The reference here is:
y = -4x-5
The slope is -4
The negative inverse of -4 would be +(1/4). Any line that has a slope of +(1/4) will be perpendicular to y=-4x+5.
The equations in the answer options are not arranged according to the standard format of y=mx+b, where m is the slope and b the y-intercept.
We could graph all the equations and look for the one(s) that are perpendicualr, but it might be safer, and faster, to rearrange them in the standard format, and then note the slope:
Slope =+(1/4)?
A. x+4y=-32
4y= -x-32
y = -(1/4)x-8 -(1/4) NO
B.4x+y=3
y = -4x + 3 -4 NO
C.4x−y=−4
y = 4x + 4 4 NO
D.4y−x=4
4y=x+4 +(1/4) <==YES
y=(1/4)x+1 [Option D has a slope of +(1/4). It will be perpendicular]

An iocele triangle ha a bae length of 126 unit and a height of 16 unit find the length of one of thoe leg
The length of one of the legs of the triangle is 65 units.
An isosceles triangle has a base length of 126 units and a height of 16 units. We need to find out the length of one of the legs of the triangle.
First of all, we will consider a perpendicular bisector of the triangle. This divides the given triangle into two equal right-angled triangles. Now, in the smaller triangle, we will use the Pythagorean theorem.
Let the length of the leg be represented by the variable "x". The length of the base of the right-angled triangle is half the length of the base of the original triangle.
x² = (16)² + (126/2)²
x = √(256 + 3,969)
x = √4,225
x = 65
Hence, the length of one of the legs of the triangle is 65 units.
