Answer:

  75°

Step-by-step explanation:

Angles CAB and DBA are consecutive interior angles where transversal AB crosses parallel lines BD and AC. So, those angles are supplementary.

  ∠DBA +∠CAB = 180°

  ∠DBA +30° = 180°

  ∠DBA = 150°

__

Angle ABC is a base angle of isosceles triangle ABC, so has measure ...

  ∠ABC = (180° -30°)/2 = 75°

__

Angle DBC is the difference of angles DBA and CBA, so is ...

  ∠DBC = ∠DBA -∠CBA

  ∠DBC = 150° - 75°

  ∠DBC = 75°

Step-by-step explanation:

The coordinate plane was developed centuries ago and refined by the French mathematician René Descartes. In his honor, the system is sometimes called the Cartesian coordinate system. The coordinate plane can be used to plot points and graph lines. This system allows us to describe algebraic relationships in a visual sense, and also helps us create and interpret algebraic concepts.

Answer:

Not really,maybe he just went in to find something,just that he didn't that's why maybe he didn't steal anything

Step-by-step explanation:

Answer:

Not necessarily. The robbers might've seen something or someone in your house and ran. They also could've heard something and thought you were home. So, if a robber breaks into your house but runs almost immediately you migt want to get your house checked out. Or, the robbers did think you were poor. Sorry.

You can do this by converting this into a ratio or a fraction

Ratio:

1 lb for 4 guinea pigs

1:4

If he was 8 lbs for x guinea pigsit would be

1:4

8:x

Multiply the first ration until the one is equal to 8, then whatever the four turns into is x

Fraction: (easier way)

1/4 (1lb for 4 guinea pigs)

8/x (8lb for x guinea pigs)

1/4 = 8/x

Multiply one until it is equal to 8

Correspond that to the 4

1*8 = 8

4*8 = 32

32 guinea pigs

Answer:

ok so when it shows something like this, also what is 45 divided by 15? it's pretty obvious to see because add this 15+15+15=45 so, three would be the answer that you need or think of it this way when it says when y=45 you about dividing the the 2 numbers to your answer

have a great day :)

Answer:

2.4 hours

Step-by-step explanation:

6 3/10 divided by 5 1/4 is 1.2. So 6 3/10 is 1.2 times more than 5 1/4. We then take the 1.2 and multiply it by 2 hours because we need to find what's 1.2 times more than 2 hours. So then you get 2.4 hours.

Answer:

The values of x and y that satisfy the equation are 2 and 2, respectively.

Step-by-step explanation:

Two complex numbers are identical if and only each pair of respective coefficients are identical on both sides. Then, we need to observe the following conditions:

Real component

[tex]4\cdot x = 8[/tex] (1)

Imaginary component

[tex]2 = y[/tex] (2)

The solution of this system of equations is [tex]x = 2[/tex] and [tex]y = 2[/tex].

The values of x and y that satisfy the equation are 2 and 2, respectively.

The values of x and y that satisfy the equation is x = 2, y = 2.

Given that,

Based on the above information, the calculation is as follows:

Now

(4) (x) = 8.........real component

x = 2

And,

2 = y..... imaginery component

Therefore we can conclude that the values of x and y that satisfy the equation is x = 2, y = 2.

Answer:

4. x = 7.5

5. x = 17.9

6. x = 18.4

Step-by-step explanation:

4. Cos(60) = x/15

x = 15*Cos(60)

x = 7.5

5. Tan(50) = x/15

x = 15*Tan(50)

x = 17.9

6. Cos(57) = 10/x

x = 10/Cos(57)

x = 18.4

Answer:

4. 7.5

5. 17.9

6. 18.4

Step-by-step explanation:

remember that you need to use SOH CAH and TOA to find these.

sin = opposite/ hypotenuse

cos = adjacent / hypotenuse

tangent = opposite / adjacent

to find angles you would choose either to use sin, cos, or tan with the two sides that they give you and you would solve with an inverse tangent

to find the side lengths, find the inverse of the formula that you used to find the angle

for example: your first problem would look like this

you have the sides of the hypotenuse and you need to find that adjacent side so this would be a cos function

60 (which is the angle) = cos^-1  [x / 15] x is the adjacent and 15 is the hypotenuse

then you start to isolate x so you do cosine to  both sides and multiply by 15

15 [cos(60)]

plug this into your calculator and TA DA

Answer:

51.2

Step-by-step explanation:

We do 80 times 0.64 (as 0.64 is the percent). This is the same thing as asking for 80% of 60.

Answer: 51.2

Step-by-step explanation:

If you want to find a part out of a number, you use the equation:

Part = Percent x whole

For this equation, you can do 64/100 x 80, because 64% is equal to 64/100

64/100 x 80 = 51.2

In conclusion, 64% of 80 is 51.2.

7). Ratio of the students who name hockey as their favorite sport to hose who name basketball.

Ratio = [tex]\frac{\text{Students preferred hockey}}{\text{Students preferred basketball}}[/tex]

         = [tex]\frac{1}{5}[/tex]

         = 1 : 5

Option W is the answer.

8). Ratio of the students whose favorite sport is either baseball or soccer to the total students,

Ratio = [tex]\frac{\text{Students preferred baseball or soccer}}{\text{Total students}}[/tex]

         = [tex]\frac{(3+8)}{19}[/tex]

         = [tex]\frac{11}{19}[/tex]

         = 11 : 19

Option O is the answer.

9). Ratio of the students who prefer soccer, basketball, baseball or hockey to those who preferred another sport,

Students who prefer soccer, basketball, baseball or hockey = 8 + 5 + 3 + 1 = 17

Students who prefer another sport = 2

Ratio = 17 : 2

Option K is the answer.

10). Ratio of total number of students to the students who preferred a sport with round ball,

Answer:

Z = 53

Y = 74

Step-by-step explanation:

so a triangle, all angles equal up to 180 and also a straight line equals 180

so, 180 - 127 = 53

it is an isosceles triangle so the bottom 2 sides are the same number so angle Z = 53

add 53 and 53 because you need to subtract it from 180 to get y

53 + 53 = 106

the subtract 106 from 180

180 - 106 = 74

so angle y = 74
