\bold{FOR \: 1st  \: image }

By straight line angles property,

▶60 + 4x +20 =180

▶80 +4x =180

▶4x = 180 -80

▶4x = 100

x = 25

So, Second angle

▶4 ×25 +20

▶100 + 20

▶120

\bold{FOR \: 2nd \: image }

3x + x =116

4x=116

x = 29

other angle = 3 ×29

=87

\bold{FOR \: 3rd \: image }

ANGLE CAB + ANGLE ACB = 90

2x + x + 30 =90

3x + 30 =90

3x = 90 - 30

3x= 60

x=20

So, angle CAB = 2 ×20 = 40

Select the three ratios that represent the numbers of blue marbles to red marbles, there are 6 blue marbles and 9 red marbles
Agata [3.3K]

Answer:

6:9 or (2:3)

Step-by-step explanation:

A ratio is a term that gives comparison of values. It helps to determine

how much of a particular thing that is compare to other thing.

Given:

numbers of blue marbles= 6

numbers of red marbles= 9

Hence, ratios that represent the numbers of blue marbles to red = 6:9

We can reduce it using factor of 3, hence the ratio becomes(2:3)

Solve for the values of x and y in each item to make the given quadrillater a parallelogram​
maria [59]

Answer:

For given parallelogram, the value of x = 114° and y = 66°

Step-by-step explanation:

(Refer figure)

Given quadrilateral ABCD is a parallelogram.

m∠A = 66°

m∠B = x°

m∠C = y°

m∠D = 114°

Since by properties of parallelogram, the both pairs of opposite sides of a parallelogram are parallel.

Opposite angles of a parallelogram are congruent ...........................(1)

Consecutive angles of a parallelogram are supplementary ................(2)

Using (1) for given parallelogram ABCD; we get,

m∠B = m∠D

m∠A = m∠C

Therefore x = 114° and y = 66°.

Using (2) to check whether the two consecutive angles are supplementary.

( m∠A + m∠D ) =  ( m∠B + m∠C ) = ( m∠C + m∠D ) = 66° + 114° = 180°

Hope it helps!!

I put an answer but I’m unsure of it, any help would be much appreciated!!
Darya [45]
First you need to change 45 feet to 540 inches.

Now you can compare the two ratios:
1 : 25 and 25 : 540

We now need to change the second ratio to a unit rate:
25:540 as a unit rate would be 1 : 21.6 and this is steeper than the a 1 : 25 drop

So, your answer would be: pipe drops to much vertically to function properly

The daily cost of renting a car is $25.00 plus $0.30 per mile driven. What is the cost of renting the car for one day and drivin
alekssr [168]

Answer: The cost of renting the car for one day and driving at 75 miles = $ 47.5 .

Step-by-step explanation:

GIven: Daily cost of renting car = $ 25.00 + $0.30 per mile driven

Let x = Total distance traveled ( in miles).

Then total cost of renting (in $)= 25+0.30x

For x= 75 miles

The  total cost of renting (in $)= 25+0.30(75)

=25+22.5

= $47.5

Hence, the cost of renting the car for one day and driving at 75 miles = $ 47.5

4. (Claim 1 Example)
Citrus2011 [14]

Answer:

D

Step-by-step explanation:

using Sohcahtoa we know that we can only use Soh (since we have the opposite,16 and the hypotenuse, 20)

D is the only one that uses the correct equation of S = o/h

(this explanation isn't the best so please search up Sohcahtoa if it doesn't make sense)
