Which of the expressions below is equal to 24/18? Select all that apply.Which of the expressions below is equal to 2418? Select all that apply.
Answer:
A, B, D
Step-by-step explanation:
Given that :
24 / 18 = 4 / 3 = 1.333
Comparing the options solutions for the options given :
3/9 ÷ 2/8 = 3/9 * 8/2 = 24 / 18 = 1.333
4/9 ÷ 2/6 = 4/9 * 6/2 = 24/18 = 1.333
5/6 ÷ 3/4 = 5/6 * 4/3 = 20 / 18
8/3 ÷ 6/3 = 8/3 * 3/6 = 24 / 18 = 1.333
Hence, expressions which are equal are :
A, B and D
Determine the y-intercept of the following equation. help pls
Answer:
0,8
Step-by-step explanation:
(-x-2)(x-4)=y
To find the x-intercept, substitute in 0 for y and solve for x. To find y-intercept, substitiue in 0 for x and solve for y.
(-0-2)(0-4)=y
(-2)(-4)=8
y=8
0,8
The train is travelling with the speed of 90km/hr. What is the distance covered in 2min?
We are given:
Speed of the train = 90 km/h
Converting the speed to km per minute:
[tex]90\frac{km}{h}* \frac{h}{60 min}[/tex] [since 1 hour = 60 minutes, h/60 minutes is equal to 1]
The 'h' in numerator and denominator will cancel out
90km / 60 min
1.5 km/min
Distance travelled in 2 minutes:
Distance = Speed * time
Distance = [tex]1.5\frac{km}{min}* 2 min[/tex]
Distance = 3 km

12. You are measuring the height of a Sitka spruce tree in Alaska. You stand 45 feet from the base of
the tree. You measure the angle of elevation from a point on the ground to the top of the tree
to be 59º. Estimate the height of the tree.
Answer:
tangent 59° = Tree height / 45 feet
Tree Height = 1.6643 * 45
Tree Height = 74.8935 Feet

Helloo!
I founded same type of question from Brainly! People who have been written this solving questions. Also search and check for this question on Brainly!! Or my advice to download course hero because there is so many subjects that you can work on it.
Can anyone help ? I’m bad at math
Answer:
Step-by-step explanation:
First you need the third angle (C).
<C + 89 + 45 = 180 All triangles = 180 degrees. Combine the left terms.
<C + 134 = 180 Subtract 134 from both sides
<C = 180 - 134
<C = 46
Next, Let BA = x
x/Sin(46) = 15/Sin(89)
x = 15*sin(46) / Sin(89)
Sin(46) = 0.7193
Sin(89) = 0.9998
x = 0.7193 * 15 / 0.9998
x = 10.7911
Note
When you are studying this material, you should note 2 things.
The first is that you are dealing with 2 ratios that are equal to each other.The second is, the side is always opposite the angle in the triangle. The two are connect. Side c = 15. It is opposite the 89o angle.sunita has to ribbons of lengths 25 inches and 35 inches he want to cut the Ribbon into strips of equal length what is the longest possible length for the strips

Answer:
Area = 1514 m^2
Step-by-step explanation:
Total Area = area of rectangle + area of circle
= (60 m × 20 m) + πr^2
= (1200 m^2) + (3.14)(10 m)^2
= (1200 m^2) + (314 m^2)
= 1514 m^2
