X = 30 degrees
Explanation:
Angle BAC = 60 degrees because of equilateral triangle. Therefore angle BAD = 120 degrees because of angles on a straight line
Angle CBA = 60 degrees, therefore angle DBA = 30 degrees because line DB and BC meet at 90 degrees.
Now do 180 - (30 + 120) = 30. X = 30

The formula for the velocity of an object is v=d/t, where v is the velocity of an object, dis the distance traveled, and t is the time elapsed, while the distance is traveled. If you had only this formula to work with, what should your first step be in determining how long it takes for light to reach Earth from the Sun? What additional information do you need to calculate this?
Answers
Answer:
To know the distance between the sun and the earth you need isolate d of the equation:
[tex]v = \frac{d}{t} \\ d = vt[/tex]
and the additional information needed is the velocity of light and the time elapsed to be in the earth
A forest covers 31,000 acres. A survey finds that 0.2 % of the forest is old-growth trees. How many acres of old-growth trees are there?
Answers
Answer:
There are 62 acres of old growth trees
Step-by-step explanation:
You would need to find 0.2% of 31,000
Lets say 0.2% of 31,000 is Y
Y = 0.2/100
Y = 0.2 ÷ 100 x 31,000
Y= 62

Step-by-step explanation:
Key skills needed: Congruent Triangles
1) We can use Triangle Congruence Rules to prove that Triangle EDF and Triangle CDF are congruent triangles.
2) Since both triangles have 1 right angle, they are both triangle triangles.
3) Both triangles share the same hypotenuse (DF)
Also, it gives us EF is 36, and FC is 36 --> This means that EF ≅ FC
Since both are Right Triangles, we can use Right Triangle HL Congruence to prove it
HL means Hypotenuse-Leg
This rule can only be applied to right angle triangles. In order to use this rule, a hypotenuse and a leg of the triangles need to proven congruent.
4) Since ΔEDF ≅ ΔCDF with Right triangle HL, we can say that < CDF is congruent to < EDF. These are corresponding parts of the triangle.
--> To say that < CDF is congruent to < EDF, we can use the theorem:
If Δs are ≅, then all corresponding parts are ≅.
5) Therefore, <CDF ≅ <EDF (which means the measures of the angles are the same value)
Since <EDF is 58°, <CDF would also be 58°

Then we will have the sides of the rectangle:

URGENT!!!! The area of a rectangular floor is 80 square feet. The length of the floor is 2 feet less than the width of the floor.
What is the width of the floor?
Drag the answers into the boxes to correctly complete the statements.
The equation Response area , where w is the width of the floor in feet, can be used to solve this problem. The width of the floor is Response area feet.
Answers
Answer:
The width of the floor is 10 ft.
Step-by-step explanation:
First, you have to form expressions of width and length in terms of w. With the given information :
width = w ft
length = (w - 2) ft
Given that the area of rectange is A = length × width so you have to subtitute the expressions and value into the formula :
A = l × w
80 = (w - 2) × w
w(w - 2) = 80
w² - 2w = 80
w² - 2w - 80 = 0
(w + 8)(w - 10) = 0
w + 8 = 0
w = -8 (rejected)
w - 10 = 0
w = 10
in a school containing 360 children, 198 are girls. What percent of the school are girls? What percent of the school are boys? How many boys are there? How many girls are there? Thank you!
Answers
Answer:
Part A)
Part B)
Part C)
Part D)
Step-by-step explanation:
we know that
The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the sample space is the total number of possible outcomes
The event space is the number of outcomes in the event you are interested in.
so
Let
x------> size of the event space
y------> size of the sample space
P=x/y
Part A) What percent of all children are girls?
we have that
y= 360 children
x=198 girls
substitute
p = 198/360 0.55
Find the percentage
0.55*100=55%
Part B) What percent of all children are boys?
we have that
y=360
x=360-198
substitute
p= 162/360=0.45
Find the percentage
0.45*100=45%
Part C) The number of girls is what percent of the number of boys?
we have that
y=162
x=198
substitute
p=198/162=1.22
Find the percentage
1.22*100= 122%
Part D) The number of boys is what percent of the number of girls?
we have that
y=198 girls
x=162 boys
substitute
p=162/198=0.8182
Find the percentage
0.8182*100=81.82%
The percentage of the school are girls is 55%.
The percentage of the school are boys is 45%.
The number of boys in the school is 162.
The number of girls in the school is 198.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, In a school containing 360 children, 198 are girls.
Therefore, The percentage of the school are girls is,
(198/360)×100%.
= 55%.
The percentage of the school are boys is,
= [(360 - 198)/360]×100%.
= 45%.
Or The percentage of the school are boys is, (100 - 55)% = 45%.
The number of boys in the school is,
(360 - 198).
= 162 boys.
The number of girls in the school is 198.
