13 POINTS FOR ANSWERS TO ALL STEPS
geometry triangles

Answers

Answer 1

Step-by-step explanation:

a) We know that triangle ABD is a right triangle, because of the right angle mark show, and the fact that BD- height, thus perpendicular.

We also know that m<A=30 degrees, due to given diagram.

The sum of all angles in a triangle is 180 degrees. Therefore, m<BDA + m<ABD + m<DAB (Usain Bolt!) = 180 degrees.

m<BAD=30 degrees, m<BDA=90 degrees

Substitute these two in the equation above. You will get that m<ABD=60 degrees.

b) Triangle ABD is a special triangle, with angles of 30,60 and 90.

We know that AD=10[tex]\sqrt{3}[/tex] units.

AD is opposite the 60 degree angle, or <ABD. It is a theorem that the angle opposite to the 60 degree angle is the height (BD) divided by [tex]\sqrt{3}[/tex]. Calculate, and what do you get? BD=10 units!

c) Use the fact that triangle ABC is an isosceles triangle.

d) Use the fact that you know the height, base, and triangle area formula: Base x 1/2 x Height.

I will say no more, but I hope you understand the rest based on your logic.

what is the least perfect squared number that is divisible divisible by

12

16

20

24

NOTE : the first one who answers gets branilast

Answers

The lowest perfect squared number that is divisible by 12,16,20,24 is 3600
1. Let's find the L.C.M
12 = 2×2×3
16 = 2×2×2×2
20 = 2×2×5
24 = 2×2×2×3
The L.C.M is 2×2×2×2×3×5 = 240
2. Now, the L.C.M 240 is not a perfect square.
3.Therefore to obtain a lowest perfect square the given number should be should have another 3 and 5 as the factor.
4. So, multiplying 240 by 15 we, get 3600 which is a perfect square and it can be divided by 12,16,20,24.
5. 3600 is the square of 60.
6.Therefore, the lowest perfect square that is divisible by 12,16,20,24 is 3600

Answer:

7. A=48

8.B=30

9. C=188

10. D=18

11. X=32

12.Y=40

Step-by-step explanation:

Answer:

7. [tex]a=48[/tex]

8. [tex]b=30[/tex]

9. [tex]c = 188[/tex]

10. [tex]d = 18[/tex]

11. [tex]x = 32[/tex]

12. [tex]y = 40[/tex]

Step-by-step explanation:

Let's do something called cross-multiplication. It's exactly what it sounds like, we multiply the top number with the denominator across the multiplication.

[tex]\frac{33}{a} = \frac{11}{16}[/tex]

[tex]11 a = 33(16)[/tex]

[tex]11a = 528[/tex]

Now we can simplify.

[tex]a=48[/tex]

So we got the answer for the first one. We can keep doing the same thing for the others.

Carlos bought 3 gallons of ice cream for $9.50. Which proportion
can be used to find the cost of 7 gallons of ice cream?

Answers

Answer:

Cost of 7 gallon ice cream = 22.167 (Approx.)

Step-by-step explanation:

Given:

Cost of 3 gallon ice cream = $9.50

Find:

Cost of 7 gallon ice cream

Computation:

Cost of 1 gallon ice cream = 9.50 / 3

Cost of 1 gallon ice cream = $3.1667 (Approx.)

So,

Cost of 7 gallon ice cream = 7 x 3.1667

Cost of 7 gallon ice cream = 22.167 (Approx.)

Answer:

x = 11.4 m

y = 21 m

man's shadow = 9.6 m

Step-by-step explanation:

measure of third angle must be 50 degrees (180 - (40 + 90))

you can take tan50° = 15/y and 'y' will equal approx. 21

to find 'x' you can take tan21° = (21-x) /25 and 21 - x = 25 · tan21°

21 - x = 9.6

-x = -11.4

x = 11.4

man's shadow is the difference of 21 and 11.4, which is 9.6

What are the slope and y-intercept of the graph of this equation?
y = 2x - 5

Answers

Answer:

In this equation, y = 2x - 5, it is already in that form and so the cumber in front of the x is the slope (2) and the constant number is the y-intercept (-5) - it's negative because of the minus sign in front of the number. So, the slope is 2 and the y-intercept is -5.

To indicate the purpose of something (to has the same meaning as so as to, in order to), for example, She came to see the doctor. b. After some verbs (advise, ask, encourage, invite, order, persuade, remind, tell, warn, expect, intend, would prefer, want, would like) which are followed by a direct object, for example, They would like you to make a speech.c. Following a noun or pronoun, to indicate what something can or will be used for, for example: I'd like a sandwich to take to school. d After certain verbs (ask, decide, explain, forget, know, show, tell, understand) followed by question words, for example, She asked me where to sit.
