True or false? Is (4,1) a solution to 3x - 2y < 10 ?

80ft^2 since for the rectangle part of the shape is 6x10. The triangular part of the shape is (4x10)/2.

Therefore,  that's (60)+(40/2)=60+20. Resulting in 80ft^2

The measure of the arcs of the circle is given by

a) The difference of arc measures mAC - mDE = 56°

b) The measure of angle 2(∠ABC ) = 56°

In circles, a sector is said to be a part of a circle made of the arc of the circle together with its two radii. This means that it is a portion of the circle formed by a portion of the circumference (arc) and radii of the circle at both endpoints of the arc.

The formula for Area of a sector is given as;

θ/360 * πr²

where;

θ is the central angle of the sector

r is radius

Now, looking at the given options we can say that the only one that represents the area of the sector is;

A = n/360 * πr²

where n is the central angle of the sector'

Given data ,

Let the measure of the arcs of the circle be

The measure of angle ∠ABC = 28°

The measure of arc mAC = 80°

The measure of arc mDE = 24°

So , the difference of arc measures mAC - mDE = 80 - 24

The difference of arc measures mAC - mDE = 56°

And , measure of angle 2(∠ABC ) = 56°

Hence , the measures of arcs of circle is solved

Answer:

Step-by-step explanation:

given the expression;

(2+√-25)(4-√-100)

Note that √-25 = √-1 * √25

√-100 = √-1 * √100

According to complex number,  √-1 = i

√-25 = 5i

√-100 = 10i

The expression becomes

(2+5i)(4-10i)

Open the parentehsis;

= 2(4)-20i+20i-50i²

=  8-50i²

Since i² = -1

The expression becomes;

8-50i² = 8-50(-1)²

8-50i² = 8-50 = -42

Hence the product of the expression is -42

Step-by-step explanation:

you add 4+46=50x2=100

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is 4 gal of pure ethanol is added to 46 gal of 2% ethanol.

In 46 gal of 2% ethanol, we have (46 x 0.02) = 0.92 gallons of pure ethanol.

When 4 gal of pure ethanol is added, total ethanol in the mixture = 4 + 0.92 = 4.92 gallons

Total mixture quantity in gallons = 46 + 4 = 50 gallons

The percentage of the ethanol in the mixture will be -

(4.92/50) x 100 = 9.84%

Therefore, the percentage of the ethanol in the mixture will be 9.84%.

BRAINLIEST?

Answer:

Step-by-step explanation:

m∠2=71° because they are vertical angles so are congruent

those 4 angles in the midle will add up to 360°

∠3+∠5=360-2*71=218 so

m∠3=218/2=109°

m∠5=109°

mostly use that the sum of angles in a Δ add to 180

m∠1=180-47-71=62°

m∠4=180-109-36=35°

m∠6=180-42-109=29°

use that opposide ∠s in a quadrinateral add to 180

m∠7=180-47-35-29= °69

m∠8=180-42-62-36= °40

Answer:

x=28

Step-by-step explanation:

-2(3x-9)+5x =-10

now we times -2 to to the inside of the parenthese

giving us

-6x+18 +5x= -10

add like terms

add -6x and 5x

-1x+18=-10

now we add like terms of the constants

minus 18 on  both sides

-1x=-28

now divide by -1

x = 28

Answer:

x = 28

Step-by-step explanation:

First, remove the parentheses by distributing -2.

-6x + 18 + 5x = 10

Next, collect the like terms.

-x + 18 = -10

Next, move the constant to the right-hand side and change its sign.

-x = -10 - 18

Next, calculate the difference

-x = -28

Lastly, change the signs on both sides of the equation.

x = 28

These are the steps to answer this equation.

Answer: The break even point is when they have sold 16 books and have made $288

Step-by-step explanation:  The costs are modeled in the equation y = 12x + 96.  x is the number of books sold.

The earnings are modeled by he equation y = 18x.

Substitute 18x for y and solve for x.

18x = 12x + 96  Subtract 12x from both sides.

6x = 96 Divide both sides by 6

x = 16

Substitute into the original equations to solve  for y

y = 12(16) + 96

y = 192 + 96

Y = 288

y = 18(16)

y = 288
