Which Is The Measure Of DBC?

Answers

Answer 1

Answer: 20°

Step-by-step explanation:

There is 180 degrees in the triangle.  ∠C is 50°,  ∠A is 80°,  ∠B is 30°, and the total adds up to 160°, so 180-160 equals 20.

Answer 2

Answer: 20 degrees

Step-by-step explanation: if you add up the angles of any triangle, the sum should always be 180. so add up angle A and angle C :

80 + 50 = 130

subtract that from 180 to find out what angle ABC is:

180 - 130 = 50

since we know that angle ABD is 30 degrees, all we have to do now is subtract that from 50:

50 - 30 = 20

angle DBC = 20 degrees

Answer:

99

Step-by-step explanation:

area of a triangle formula = [tex]\frac{bh}{2}[/tex]

where b = base length and h = height

The triangle shown has a base length of 11 and a height of 18

Using this information we plug in the values into the formula

[tex]A=\frac{11*18}{2} \\11*18=198\\\frac{198}{2} =99[/tex]

Hence the area of the triangle is 99ft²

PLEASE HELP PROBLEM IN PHOTO!

Answers

Answer: Should be 130

Step-by-step explanation:

A is 80 180-80 is 100. Since it’s an isosceles you can divide by 2 and the two angles would be the same. 100/2 is 50 because two remote interior angles is equal to the exterior angle, 50+80 is 130, d is 130

Answer:

Angle D is 130 degrees

Step-by-step explanation:

180-80=50

Angles b and c are the same and will both be 50 degrees.

The angle of a straight line is 180 degrees.

Since angle c is 50 degrees, then the other angle (d) will have to be 130, so that together the total of the two is 180 degrees.

Find the amount of time. I = $174, P = $1450, r = 8%

Answers

Answer:

1.5

Step-by-step explanation:

first you multiply 1450 by 8% to get 116 then divide 174 by 116 to get 1.5

The amount of time will be "1.5".

Given:

I = $174P = $1450r = 8% or, 0.08

As we know the formula,

→     [tex]P = \frac{I}{rt}[/tex]

By substituting the values, we get

→ [tex]1450 = \frac{174}{0.08\times t}[/tex]

By applying cross-multiplication, we get

→  [tex]116t = 174[/tex]

        [tex]t = \frac{174}{116}[/tex]

          [tex]= 1.5[/tex]

Thus the above approach is correct.

A community swimming pool has a deep end and a shallow end. The volume of water in the deep end can be represented by (2x2+12x+10) ft3 and the volume of the water in the shallow end can be represented by (4x2−100)ft3.

Write the equivalent expression ("simplified") that represents the total volume of the water in the pool in ft3.

Answers

Answer:

The total volume of water in the pool  = ( 6x^3 + 12x^2 - 90x ) ft^3

Step-by-step explanation:

The volume of water in the deep end = (2x^3 + 12x2 + 10x) ft^3

The volume of water in the shallow     =  (4x^3 -100x) ft^3

The total volume of water in the pool  = (2x^3 + 12x2 + 10x)  +  4x^3 -100x)

                                                              = ( 6x^3 + 12x^2 - 90x ) ft^3

Add 9 to the left side of the equation.

Answer:

43 1/3

Step-by-step explanation: Not sure what that second part it but for that equation it is 43 1/3 because you need to isolate the variable by adding the 18 1/3 to the 25 and whatever that equals is your answer so I added

g-18 1/3=25

Fares has a container filled with 540 grams of tea leaves. Each morning, he uses 6 grams to make a cup of tea.

Write an expression to represent the grams of tea leaves remaining after x days.

How many grams of tea leaves will remain after 17 days? Show your work.

Answers

Answer:

Step-by-step explanation:

Quantity of tea leaves used  for one morning = 6 grams

Quantity of tea leaves used for 'x' days = 6 *x = 6x grams

Quantity of tea leaves left after x days = 540 - 6x

Expression: 540 - 6x

Quantity of tea leaves remaining after 17 days = 540 - 6*17

                                                                             = 540 - 102

                                                                             = 438 grams
