Answer:

65

Step-by-step explanation:

Step-by-step explanation:

officially, complementary angles complete each other to a total sum of 90 degrees.

supplementary angles complete each other to a total sum of 180 degrees.

angle 1 = 19× angle 2

90 = angle 1 + angle 2 = 19×angle 2 + angle 2 = 20×angle 2

angle 2 = 90/20 = 9/2 = 4.5 degrees.

angle 1 = 19×4.5 = 85.5 degrees.

and so, it seems to me, your teachers made a severe definition mistake and aimed for 180 degrees instead of the correct 90 degrees.

in that case, everything doubles.

angle 2 = 9 degrees

angle 1 = 171 degrees

If measure of an angle is 19-times measure of its complementary-angle, then measure of one angle is 85.5° and other is 4.5°.

Let us denote the measure of the angle as = "x" degrees.

The complementary angle is the angle that, when added to the given angle, forms a 90-degree angle.

The complementary-angle to "x" degrees is = (90 - x) degrees,

We know that the measure of the angle is nineteen times the measure of its complementary angle, we can write the equation as :

x = 19(90 - x),

x = 1710 - 19x,

20x = 1710,

x = 1710/20,

x = 85.5,

Therefore, the measure of the angle is 85.5 degrees. The measure of its complementary angle is 90 - 85.5 = 4.5 degrees.

Answer:

Step-by-step explanation:

Start with the standard equation of a straight line, y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).

We know m, so:

y = 2x + b

Now find b by using the given point (-1,-3)

y = 2x + b

-3 = 2(-1) + b

b = -1

The equation is y=2x-1

Answer:

The y-intercept is -2 and the slope is 2/3

27/50

Step-by-step explanation:

Answer:

27/50

Step-by-step explanation:

54 is another way of writing 54 hundredths, or as a fraction, 54/100. Asking for a simplified fraction is asking you to reduce the numerator and denominator by any common terms. 54 and 100 are both divisible by 2, so we get to 27/50. These have no factors in common, so 27/50 is our simplified fraction.

Answer: 39

Step-by-step explanation: 1/2   = 6

                                             13/4 = x

If Satchmo bought half pound of mangoes for $6 then he pay $39 for 13/4 pounds of mangoes.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that Satchmo bought half pound of mangoes for $6

We need to find the amount he has to pay for 13/4 pounds of mangoes.

Let x be the  amount he has to pay for 13/4 pounds of mangoes..

We find the value of x by forming a proportional equation by given data.

1/2/6=13/4/x

1/12=13/4x

Apply cross multiplication

4x/12=13

x/3=13

x=39

Hence, Satchmo pay $39 for  13/4 pounds of mangoes.

Answer:

D. 1356.5 cm³

Step-by-step explanation:

The volume of a cone can be represented by:

V = (π)(r²)(h/3)

Substitute the known values:

π = 3.14

r = 12

h = 9

V = (3.14)(12²)(9/3)

Square 12.

V = (3.14)(144)(9/3)

Divide 9 by 3.

V = (3.14)(144)(3)

Multiply 3.14 and 144.

V = (452.16)(3)

Multiply 452.16 and 3.

V = 1356.48

Round to the nearest tenth.

V = 1356.5.

Answer:

You can pay a maximum of $84.

formula is:

84 = 40 + .22*m

subtract 40 from both sides of this equation to get:

44 = .22*m

divide both sides of this equation by .22 to get:

44/.22 = m

simplify to get:

m = 200
