Step-by-step explanation:
Given
[tex]D = s.t[/tex]
Required
Which represents 400km
This question requires options. Since none were given, I will answer on a general term.
Situation 1:
s = 20km/h and t = 20h
[tex]D = s.t[/tex]
[tex]D = 20km/h * 20h[/tex]
[tex]D = 400km[/tex]
Situation 2:
s = 10km/h and t = 40h
[tex]D = s.t[/tex]
[tex]D = 10km/h * 40h[/tex]
[tex]D = 400km[/tex]
Situation 3:
s = 40km/h and t = 10h
[tex]D = s.t[/tex]
[tex]D = 40km/h * 10h[/tex]
[tex]D = 400km[/tex]
So, all you literally have to do is multiply the values of s and t. If the product gives 400, then; that situation is D = 400

The measure of an exterior angle of a triangle is 40°. What is the sum of the measures of the corresponding remote interior angles?
Answer:
40 degrees
Step-by-step explanation:
Because there are 180 interior angles in a triangle, you need one of the sides. If an angle's exterior is 40 degrees, we know that the interior angle is 140 degrees. This means that the sum of the other interior angles have to be 40 as 180-140 is 40.
If an angle's exterior is 40 degrees, we know that the interior angle is 140 degrees. This means that the sum of the other interior angles have to be 40 as 180-140 is 40°.
What are Triangle theories?A triangle is the smallest polygon with three sides and three interior angles.Theorem 1: The Sum of Angles property of a triangle states that the sum of the interior angles of a triangle is 180°.Theorem 2: If you lengthen one side of a triangle, the resulting exterior angle is the sum of the two opposite interior angles of the triangle.A exterior angle equals the sum of his two other angles in the triangle, so the sum of the angles in the triangle is 180 degrees. In other words, the other two angles of the triangle (which together make up the exterior angle) must be combined with the third angle to make a 180 degree angle.40 degrees is the sum of the measures of the corresponding remote interior angles.
Because there are 180 interior angles in a triangle, you need one of the sides. If an angle's exterior is 40 degrees, we know that the interior angle is 140 degrees. This means that the sum of the other interior angles have to be 40 as 180-140 is 40°.

Answer:
The cosine of A is equal to [tex]\frac{3\sqrt{58}}{58}\\[/tex]
Step-by-step explanation:
Cosine is is calculated as adjacent over hypotenuse. The line adjacent to A is 3 in length.
So we can say that the cosine is equal to 3/√58, but need to multiply it by √58 / √58 to ensure we have a non-radical denominator
[tex]A = \frac{3}{\sqrt{58}}\\A = \frac{3\sqrt{58}}{58}\\[/tex]
sarita's father's age is 49 years his age is 4 years more than three times Sarita age find the present age of Sarita
Answer:
15years
Step-by-step explanation:
Let the present age of sarita be x
Sarita father age = 49years
If his father age is 4 years more than three times Sarita age, this is expressed as;
49 = 3x + 4
Sind x
3x = 49-4
3x = 45
x = 45/3
x = 15
hence present age of sarita is 15years

Answer:
a.(10,23)
b.(7,30)
e.(20,20)
Step-by-step explanation:
We are given that
x=Width of garden
y=Length of garden
According to question
[tex]x\geq 5[/tex]
[tex]y\geq 20[/tex]
Perimeter of rectangle=[tex]2(x+y)[/tex]
Where x=Width of rectangle
y=Length of rectangle
Fencing used =[tex]2(x+y)[/tex]
[tex]2(x+y)\leq 80[/tex]
First we change inequality into equality
[tex]x=5[/tex]...(1)
[tex]y=20[/tex]...(2)
[tex]2(x+y)=80[/tex]
[tex]x+y=40[/tex]...(3)
Substitute x=0 in equation (3)
[tex]y=40[/tex]
Substitute y=0 in equation (3)
[tex]x=40[/tex]
Substitute x=0 and y=0 in equation (3)
[tex]2(x+y)\leq 80[/tex]
[tex]0\leq 80[/tex]
It is true. Therefore, the shaded region below the line.
[tex]0\geq 5[/tex]
[tex]0\geq 20[/tex]
These are false equation .Therefore, the shaded region above the line.
Substitute x=5 in equation (3)
[tex]5+y=40[/tex]
[tex]y=40-5=35[/tex]
Substitute y=20 in equation (3)
[tex]x+20=40[/tex]
[tex]x=40-20=20[/tex]
Intersection point of equation (1) and (3) is (5,35) and intersect point of equation (2) and (3) is (20,20).
Now,
a.(10,23)
Substitute in
[tex]2(x+y)\leq 80[/tex]
[tex]2(10+23)\leq 80[/tex]
[tex]66\geq 80[/tex]
10>5 and 23>20
it satisfied all inequality.
Hence, it is a solution.
b.(7,30)
7>5
30>20
[tex]2(7+30)=74<80[/tex]
it satisfied all inequality.
Hence, it is a solution.
c.(18,25)
18>5
25>20
[tex]2(18+25)=86>80[/tex]
It does not satisfied third inequality
Hence, it is not a solution.
d.(8,35)
8>5
35>20
[tex]2(8+35)=86>80[/tex]
It does not satisfied third inequality
Hence, it is not a solution.
e.(20,20)
[tex]2(20+20)=80[/tex]
20>5
20=20
it satisfied all inequality.
Hence, it is a solution.

Step-by-step explanation:
The diagonals of a rectangle have length 12 and intersect in a 40 degree angle. Find the length and width rounded to the nearest tenth.
Answer:
Length is 7.7 and width is 9.2
Step-by-step explanation:
The length and width of the rectangle will be the y and x coordinate of the diagonal line at angle of 40 degrees
Length L = dsin theta
Width W = d coos theta
d is the length of the diagonal
Given
d = 12
theta = 40°
Substitute
Length = 12sin40°
Length = 12(0.6428)
Length = 7.7135
Length ≈ 7.7
Width = 12cos 40
Width = 12(0.7660)
Width = 9.192
Width = 9.2
Hence the length is 7.7 and width is 9.2

Step-by-step explanation:
Cameras R Us has a sale for 25% off camera bags, which is a discount of $20. To find the original cost of the camera bag, Tara creates the following diagram.
A 2-column table with 6 rows. Column 1 has entries 20 percent, 20 percent, 20 percent, 20 percent, 20 percent, Total 100 percent. Column 2 has entries 25 dollars, 25 dollars, 25 dollars, 25 dollars, 25 dollars, blank total.
What errors did Tara make in her diagram? Check all that apply.
There should be 5 rows labeled 20%.
The 25 should be for each percent, not dollar amounts.
The percents do not add up to a whole of 100%.
There should be 4 columns of 25% that each equal $20.

Find the smaller of 2 consecutive integers, x, if the sum of the smaller and 4 times the larger is 44.
Answer:
8
Step-by-step explanation:
Find the smaller of 2 consecutive integers, x, if the sum of the smaller and 4 times the larger is 44.
Two consecutive integers are represented as:
Smaller integer = x ,
Larger Integer = x + 1
If the sum of the smaller and 4 times the larger is 44
x + 4(x + 1) = 44
x + 4x + 4 = 44
5x + 4 = 44
5x = 44 - 4
5x = 40
x = 40/5
x = 8
Therefore, the smaller of 2 consecutive integers which is x = 8
