Answer:

[tex]\angle ABC=(46)^{\circ}[/tex]

Step-by-step explanation:

Given: BD bisects [tex]\angle ABC[/tex]

[tex]\angle ABD=(4x-5)^{\circ}\\\angle DBC=(3x+2)^{\circ}[/tex]

To find: [tex]\angle ABC[/tex]

Solution:

A bisector of an angle divides it into angles of equal measures.

As BD bisects [tex]\angle ABC[/tex], [tex]\angle ABD=\angle DBC[/tex]

Put [tex]\angle ABD=(4x-5)^{\circ}\,,\,\angle DBC=(3x+2)^{\circ}[/tex]

[tex]\angle ABD=\angle DBC\\(4x-5)^{\circ}=(3x+2)^{\circ}\\4x-3x=2+5\\x=7^{\circ}[/tex]

So,

[tex]\angle ABD=(4x-5)^{\circ}=(4(7)-5)^{\circ}=(28-5)^{\circ}=(23)^{\circ}\\\angle DBC=(3x+2)^{\circ}=(3(7)+2)^{\circ}=(21+2)^{\circ}=(23)^{\circ}[/tex]

[tex]\angle ABC=\angle ABD+\angle DBC\\=(23)^{\circ}+(23)^{\circ}\\=(46)^{\circ}[/tex]

A bisector divides lines, angles and shapes into equal segments

The measure of angle ABC is 46 degrees

The given parameters are:

Given that line BD is the bisector of angle ABC, it means that:

[tex]\angle ABD = \angle DBC[/tex]

and

[tex]\angle ABC = 2\times \angle ABD[/tex]

So, we have:

[tex]4x - 5 = 3x +2[/tex]

Collect like terms

[tex]4x - 3x = 5 +2[/tex]

Evaluate like terms

[tex]x = 7[/tex]

Recall that

[tex]\angle ABC = 2\times \angle ABD[/tex]

So, we have:

[tex]\angle ABC = 2 \times (4x - 5)[/tex]

Substitute 7 for x

[tex]\angle ABC = 2 \times (4\times 7 - 5)[/tex]

[tex]\angle ABC = 2 \times (28 - 5)[/tex]

[tex]\angle ABC = 2 \times 23[/tex]

[tex]\angle ABC = 46[/tex]

Hence, the measure of angle ABC is 46 degrees

Answer:

[tex]c=\dfrac{27}{40}\\[/tex]

Step-by-step explanation:

We are required to solve for c in the equation: [tex]\dfrac{1}{8}+c= \dfrac{4}{5}[/tex]

Step 1: Collect like terms

[tex]\dfrac{1}{8}+c= \dfrac{4}{5}\\c= \dfrac{4}{5}-\dfrac{1}{8}[/tex]

Step 2: Find the Lowest Common Multiple of the denominators

LCM of 8 and 5 is 40

Step 3: Multiply all through by 40

[tex]40c= \dfrac{4}{5}*40-\dfrac{1}{8}*40[/tex]

Step 4: Simplify

40c=32-5

40c=27

Step 5: Divide both sides by 40 and simplify if possible.

[tex]c=\dfrac{27}{40}\\[/tex]

Answer:

[tex]\frac{224}{10}=22.4\\ \frac{5315}{10}=531.5\\\frac{3783}{100}=37.83\\ \frac{34502}{1000}=34.502[/tex]

Step-by-step explanation:

To solve the problem, we need to write each fraction in decimal form.

Notice that each denominator is 10 based, which means we only have to move the decimal point according to the total number of zeros have the denominators. If the denominator is 10, we move the decimal point one spot to the left, if the denominator is 1000, we move the decimal point three spots to the left, and so on.

[tex]\frac{224}{10}=22.4\\ \frac{5315}{10}=531.5\\\frac{3783}{100}=37.83\\ \frac{34502}{1000}=34.502[/tex]

Answer:

3 days

Step-by-step explanation:

Some of Hannah‘s plants need water every 1 day.

Some need water every third(3) day.

If she waters them all today, we are to determine when next she will waters them all again.

To do this, we find the lowest common multiple of 1 and 3.

L.C.M of 1 and 3=3

Therefore, in 3 days time, she will water them all again.

Answer:

55% of the people surveyed were satisfied with the​ car

Step-by-step explanation:

The proportion of people surveyed who were satisfied with the car is the number of people who said they would buy that type of car again divided by the total number of people survied.

The percentage is the proportion multiplied by 100.

We have that:

2,300 people surveyed

1,265 said they would buy that type of car again.

1265/2300 = 0.55

0.55*100 = 55%

55% of the people surveyed were satisfied with the​ car

Step-by-step explanation:

total cost =    r*p*n

                   ---------------

                     1- (1+r) ^-n

Where r is the loan rate, p is the principal, n is the number of payments

rate = 4.04% / 12 months

total cost = (.0404/12)* 125000* 240

Given our current rail fare of £16.25, we are looking for the price of the rail fare after a 5% increase.

To find the value of a 5% increase, we can multiply the rail fare by 1.05 since it is 5% added to the total value.

Or, we can multiply the rail fare by 5 and then divide by 100 to get how much will be added onto it.

Let's do both of them:

Increase: 5%

Equation: 1.05 x 16.25

1.05 x 16.25 = 17.06 rounded to the nearest cent

Rail Fare after 5% increase:  £17.06

Increase: 5%

Equation: (5 x 16.25)/100

81.25/100 = .81 rounded to nearest cent

Then, we add them together.

16.25 + 81 = 17.06

Rail Fare after 5% increase:  £17.06

The temperature in degree Fahrenheit is (c) 122

The function is given as:

[tex]C = \frac 59(F - 32)[/tex]

When the temperature is 50 degrees Celsius, it means that:

C =50

Substitute 50 for C in [tex]C = \frac 59(F - 32)[/tex]

[tex]50 = \frac 59(F - 32)[/tex]

Multiply through by 9

[tex]450 = 5(F - 32)[/tex]

Divide both sides by 5

[tex]90 = F - 32[/tex]

Add 32 to both sides

[tex]F = 90 +32[/tex]

[tex]F = 122[/tex]

Hence, the temperature in degree Fahrenheit is (c) 122

Answer:

B = 80

Step-by-step explanation:

y = 4x

Combine like terms

3.5x = 280

The number of posters that Jason needs to sell so that the cost and revenue are equal will be 80. Option B is correct.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The amount of revenue in dollars, y, that Jason receives from selling x posters is given by the equation y = 4x. The cost of producing x posters is given by the equation y = (1/2)x + 280.

Then the number of posters that Jason needs to sell so that the cost and revenue are equal will be given as,

4x = (1/2)x + 280

4x - (1/2)x = 280

(7/2)x = 280

7x = 560

x = 80

The number of posters that Jason needs to sell so that the cost and revenue are equal will be 80.
