URGENT!!! WILL MARK BRAINLIEST!Find The Measure Of Angle DBE Then Find The Measure Of ABD?

Answers

Answer 1

Answer:

m<DBE =50°

m<ABD=150°

Step-by-step explanation:

Because of Straight Angles, All the angles will add up to 180 degrees

Let x be m<DBE

40+x+70+20=180

x+130=180

x=50

m<DBE will be 50 degrees

To find the m<ABD, we add m<FBA, m<FBE, m<DBE.

70+50+30=150

m<ABD = 150

Answer 2

Answer:

angle DBE=

Step-by-step explanation:

We know that angle ABE is a right angle because 70+20=90. Therefore angle CBE is also a right angle.

Now, 90-40=50 (angle DBE's measure)

Based on this, we can know that 20+70+50=140. Angle ABD is 140 degrees.

after eating at a restaurant the bill for your table is $62.50. There is a 6% sales tax and you want to leave a tip for 18% based on the pre-tax amount. How much money do you need to cover your final bill?

Answers

Answer:

Step-by-step explanation:

Your bill is $62.50

$62.50 * .06 = $3.75 (this is your sales tax added)

So your total is up to: $66.25

Adding the tip the same way using $66.25 *.18 = $11.93

Tip would be $11.93

Total coming to: $78.17

hope this helps

Answer:

$77.50

Step-by-step explanation:

Tax:

62.50x0.06= 3.75

3.75+62.50= 66.25

Tip:

62.50x0.18= 11.25

Answer:

66.25+11.25= 77.50

How much of each metal is needed to make 3.6 kg of this alloy?

Answers

Answer:

0.4kg, 1.4kg and 1.8kg

Step-by-step explanation:

Given parameters:

         Mass of alloy = 3.6kg

         Ratio of elements in the alloy = 2:7:9

Unknown:

Mass of each element in the alloy = ?

Solution:

To find the mass of each element in the alloy, first find the sum of the ratio;

              2+7+9 = 18

Mass of nickel  = [tex]\frac{2}{18}[/tex] x 3.6 = 0.4kg

Mass of zinc = [tex]\frac{7}{18}[/tex] x 3.6 = 1.4kg

Mass of copper = [tex]\frac{9}{18}[/tex] x 3.6 = 1.8kg

The mass of each metal is 0.4kg, 1.4kg and 1.8kg

Identify the y-intercept and the axis of symmetry for the graph of f(x) = 10x^2 + 40x + 42.
a
42; x = 4
b
42; x = –2
c
–42; x = 2
d
0; x = –4

Answers

Answer:

b)42, x=-2

Step-by-step explanation:

Answer:

The option 'b' is correct.

Step-by-step explanation:

Given the function

[tex]f\left(x\right)\:=\:10x^2\:+\:40x\:+\:42[/tex]

Determining the y-intercept

The y-intercept can be obtained by setting the value x = 0

[tex]y\:=\:10x^2\:+\:40x\:+\:42[/tex]

[tex]y\:=\:10\left(0\right)^2\:+\:40\left(0\right)\:+\:42[/tex]

    [tex]= 0+0+42[/tex]

    [tex]=42[/tex]

Therefore, the y-intercept is:

(0, 42)

Determining the axis of symmetry

Given the equation

[tex]y=\:10x^2\:+\:40x\:+\:42[/tex]

For a parabola in standard form [tex]y=ax^2\:+\:bx\:+c[/tex]

the axis of symmetry is the vertical line that goes through the vertex

[tex]x=\frac{-b}{2a}[/tex]

so

The  axis of symmetry for [tex]y=ax^2\:+\:bx\:+c[/tex]  is [tex]x=\frac{-b}{2a}[/tex]

[tex]a=10,\:b=40[/tex]

[tex]x=\frac{-b}{2a}[/tex]

[tex]x=\frac{-40}{2\cdot \:10}[/tex]

[tex]x=-2[/tex]

Therefore, the option 'b' is correct.

An employee worked 36 hours last week. This week, she worked 48 hours. Find the percent increase. Round to the nearest percent.

Answers

Answer:

To the nearest percentage, percent increase is 33%

Step-by-step explanation:

Mathematically;

Percentage increase = (new - old)/old * 100%

new = 48 hours

old = 36 hours

% increase = (48-36)/36 * 100%

12/36 * 100%

1/3 * 100%

= 33.33%

Answer: 33% increase

There were 43 children at the playground. Now there are 27 children at the playground. How many children left the playground? Ben says that 13 children left the playground. He thinks that 43 – 30 is easier to subtract than 43 – 27. He subtracts 43 – 30 and gets 13. Why is Ben's reasoning not correct?

Answers

Ben is incorrect because Ben did not answer the question according to the available information. The fact that subtracting 43 from 30 is easier for Ben does not mean it is the correct answer.

Quadrilateral ABCD undergoes a reflection across the x-axis to form quadrilateral a b c d the coordinates of a r the reflected quadrilateral a b c d is then translated three units to the right and third and two units up to form quadrilateral a quotation b quotation quotation see quotation

Answers

Solution :

From the figure,

The coordinates of --

A = (-5,-3)

B = (-6,-1)

C = (-3,-1)  

D = (-2,-3)

When it undergoes reflection about x-axis, we have the coordinates of the quadrilateral as

A' = (-5,+3)

B' = (-6,+1)

C' = (-3,+1)

D' = (-2,+3)

Now A'B'C'D' is translated 3 units to right, so the coordinates will be --

A" = (-2,3)

B" = (-3,1)

C" = (0,1)

D" = (1,3)

When the quadrilateral moves third and two units up, we get

A"' = (3,3)

B"' = (2,1)

C"' = (5,1)

D"' = (6,3)
