Simplify 19 - 1.67 + (2.4)

Answers

Answer:

19.73.

Step-by-step explanation:

Given : 19 - 1.67 + (2.4).

To find : simplify.

Solution : We have given 19 - 1.67 + (2.4).

By the BODMAS rule :

First we open the parenthesis

19 - 1.67 + 2.4

Now we solve the addition operation

19+2.4 -1.67

21.4 -1.67.

Now we will solve the subtraction operation :

19.73.

Therefore, 19.73.

The answer is 19.73 because 19 minus 1.67 is 17.33 and 17.33 plus 2.4 is 19.73

Points F and G lie on the graph of the equation y = −0.25x.What are the y-coordinates for each point?

Point F: (4,
) Point G: (–8,
)

Answers

All we need to do is apply these points into the function themselves.

For point F, y = -0.25(4) = -1
For point G, y = -0.25(-8) = 0.25(8) = 2

Point F's y-coord is -1 and Point G's y-coord is 2.

He measures of the angles of △ABC are given by the expressions in the table.Angle Measure
A 48°
B (6x−28)°
C (2x)°

Find the value of x. Then find the measures of angles B and C.

Enter your answers in the boxes.

x =

m∠B=

m∠C=

Answers

The required measure angles B and C of are 92° and 40° and value of x = 25.

Given,

The measures of the angles in △ABC are 48°, (6x-28)° , (2x)°.

We have to find,

The value of x Then measures of angles B and C.

According to the question,

The sum of all internal angles in a triangle is always equal to 180°.

48° + 6x − 28° + 2x° = 180

8x + 20 = 180

8x = 180 - 20

8x = 160

x = 20

The required value of x = 20.

Then, The required angle are,

6x - 28 = 6(20) - 28 = 92°

And 2x = 2(20) = 40°

The required angles are 92° and 40° .

You first have to find the value of x, which you can do by creating an equation as you know that all angles in a triangle add up to 180°:
6x - 28 + 48 + 2x = 180
8x + 20 = 180
- 20
8x = 160
÷ 8
x = 20
Now you can substitute it in:
Angle B = (6 ×20) - 28 = 120 - 28 = 92°
Angle C = 2 × 20 = 40°

The function A(b) relates the area of a trapezoid with a given height of 12 andone base length of 9 with the length of its other base.
It takes as input the other base value, and returns as output the area of the
trapezoid.
A(b) = 12.579
Which equation below represents the inverse function B(a), which takes the
trapezoid's area as input and returns as output the length of the othef base?

Answers

Answer:

$B(a)=(a)/(6)-9$

Step-by-step explanation:

see the attached figure , to better understand the problem

we have

$A(b)=12((b+9)/(2))$

where

A(b) ---> is the trapezoid's area

b ---> is the other base value

Solve the equation for b

That means ----> isolate the variable b

Divide 12 by 2 right side

$A=6(b+9)$

Divide by 6 both sides

$(A)/(6)=b+9$

subtract 9 both sides

$(A)/(6)-9=b$

Rewrite

$b=(A)/(6)-9$

Convert to function notation

$B(a)=(a)/(6)-9$
