Answer 1

Answer:

To prove : ΔDEC ~ ΔDAB

angle DEC = angle DAB...... ( Corresponding angles when Line EC || Line AB and EC being the transversal)

angle EDC = angle ADB......( Common angle D)

therefore, ΔDEC ~ ΔDAB by A - A test of similarity.

Answer:

m<E = [tex]77^{o}[/tex]

Step-by-step explanation:

From the diagram, ΔACE and ΔBDE are similar. So that comparing its angles, we have;

(8x + 4) = (9x - 5)

8x + 4 = 9x - 5

5 + 4 = 9x - 8x

x = 9

Thus,

(8x + 4) = 8(9) + 4 = 76

(9x - 5) = 9(9) - 5 = 76

3x = 3(9) = 27

From ΔACE,

3x + (8x + 4) + m<E = 180 (sum of angles in a triangle)

27 + 76 + m<E = 180

m<E = 180 - 103

m<E = [tex]77^{o}[/tex]

2) What is the slope in the equation y=2x + 3?

Answers

2 the answer is just 2.

Answer:

2

Step-by-step explanation:

y = mx + b

y = 2x + 3

m is the slope. So of we look in the equation 2 is in the m place so 2 is the slope. Hope this helps, thank you :) !!

45/120 (45 times out of 120 times)

Step-by-step explanation:

3/8 = x/120

x = 45

Answer:

b

Step-by-step explanation:

Hey There!

So when finding probabilities we want to find how many even numbers there are and divide that by the amount of numbers

we see that there are 3 even number ( 2, 16 and 8) and there are 8 numbers in total

So in one spin the probability of it landing on an even number is 3/8

Now to find the probability it will land on an even number in 120 spin we multiply 3/8 and 120

[tex]\frac{3}{8} x 120=45[/tex]

So the reasonable prediction of it landing on an even number out of 120 spins is 45

A butcher has 15 and 3/4 pounds of steaks and portions them into 7 sealed packs. How many pounds does each pack of steak weigh? *

Answers

Answer:

9/4 or 2 and 1/4 pounds

Step-by-step explanation:

Convert 15 and 3/4 into an improper fraction

15*4+3 = 63

63/4

63/4 ÷ 7

9/4

Thus, each pack weighs 9/4 pounds

Answer:

2 1/4 pounds each

Step-by-step explanation:

Convert 15 1/4 into a decimal (15.75) then divide by seven (15.75 ÷ 7 = 2.25)

and then convert 2.25 back into a fraction, 25 is 1/4 of 100 so the answer is 2 1/4

Step-by-step explanation:

its an acute angle be cause its small than a right angle

Answer:

angle AED =  70 degrees

angle x = 10 degrees

Step-by-step explanation:

since angle ABD = 110 degrees, major arc AED = 2(110) = 220 degrees

since angle ADB = 40 degrees, minor arc AB = 2(40) = 80 degrees

minor arc BD = 360 - 220 - 80 = 60 degrees

arc AB + arc BD = arc ABD

arc ABD = 80 + 60 = 140 degrees

angle AED = 1/2 (140) = 70 degrees

angle EAD = angle AED because isosceles

arc ED = 2(70) = 140 degrees

arc AE = arc AED - arc ED = 80 degrees

angle x = 1/2(arc AE - arc BD) = 1/2(80 -60) = 10 degrees

When xb= 12, y = 8. Find x when y = 12

Answers

Answer:

If it is direct proportionality, then y = kx where k is a constant.  Use the given information to find k:

 

8 = k(12) ⇒ k = 8/12 = 2/3

 

y = (2/3) x

 

For y = 12,

 

12 = (2/3) x ⇒ x = (3/2)*12 = 18

 

x = 18 when y = 12
