Evaluate -9 - (-4)

Answers

Answer:

The answer should be -5.

Step-by-step explanation:

Remember that if there are two negative signs next to each other then it will turn into a positive sign, in which you get the equation -9 + 4.  Your answer should be -5 when you add 4 from -9.

For these questions, give your answers to 1 decimal place.

how many solutions does the system of equations have?(1 point)
3x=-12y+15 and x+4y=5
A-one
B-two
C-infinitely many
D-none

Answers

Answer:

c

Step-by-step explanation:

First, I'll isolate the x in x+4y=5 to match with the other equation.

The new equation would be x= -4y+5

Next, we will multiply one equation by 3 and the other by -1 for both to match with the other.

-1(-12y + 15 = 3x )

3(-4y + 5 = x)

The new equations would be :

12y - 15 = -3x

-12y + 15 = 3x

Add the equations and you get

0 = 0

The equation has an infinite amount of solutions

For the question on the left:

The number line counts by 0.3 every time. For each value in front of -0.5, just add 0.3 and that will be the next value.

For the question on the right:

-1/3 > -5.4 , because negative numbers closer to zero are bigger.

ABCD is a rectangle. a) calculate the distance AE
b) calculate the shaded area

Answers

Answer:

a)  [tex]AE=4\sqrt{3}[/tex]

b) [tex]A_s=16(4\sqrt{3}-\pi)\ cm^2[/tex]

Step-by-step explanation:

Lines in a Circle

(a)

Points AEO form a right triangle, which hypotenuse is the radius of the larger circle (8 cm) and one of its legs is the radius of the smaller circle (4 cm).

Thus, the distance AE is calculated by using the Pythagora's Theorem:

[tex]AE^2=8^2-4^2[/tex]

[tex]AE^2=64-16=48[/tex]

[tex]AE=\sqrt{48}[/tex]

Since 48=16*3:

[tex]AE=\sqrt{16}\sqrt{3}[/tex]

[tex]\boxed{AE=4\sqrt{3}}[/tex]

(b)

The shaded area is the area of the rectangle ABCD minus the area of the smaller circle:

[tex]A_s=A_r-A_c[/tex]

The rectangle has a length of twice AE:

[tex]L=8\sqrt{3}\ cm[/tex]

And a width equal to the diameter of the smaller circle:

[tex]W=8\ cm[/tex]

The area of the rectangle is:

[tex]A_r=8\sqrt{3}\ cm*8\ cm[/tex]

[tex]A_r=64\sqrt{3}\ cm^2[/tex]

The area of the smaller circle is:

[tex]A_c=\pi\ r^2[/tex]

[tex]A_c=\pi\ 4^2\ cm^2[/tex]

[tex]A_c=16\pi\ cm^2[/tex]

Thus, the shaded area is:

[tex]A_s=(64\sqrt{3}-16\pi)\ cm^2[/tex]

Factoring:

[tex]\boxed{A_s=16(4\sqrt{3}-\pi)\ cm^2}[/tex]

a. the length of AE is: 6.9 cm

b. the shaded area is: 60.13 sq. cm.

Recall:

Area of rectangle = length × widthArea of circle = πr²

a. Find AE:

Considering right triangle AOE, apply the Pythagorean Theorem to find AE, given that,

EO = 4 cm

AO = 8 cm

Thus:

AE = √(AO² - EO²)

AE = √(8² - 4²)

AE = 6.9 cm

b. Shaded Area = Area of rectangle - area of circle

Area of rectangle = length × width = 2(6.9) × 2(4) = 110.4 sq. cm

Area of circle = π(4)² = 50.27 sq. cm

Shaded Area = 110.4 - 50.27 = 60.13 sq. cm.

The side length of a square is 8 cm. what is the area? What is the perimeter?

Answers

Answer:

Area = 64 cm² ; Perimeter = 32 cm

Step-by-step explanation:

Since we know that the side lengths of a square are all equal, this means that all 4 square lengths are 8 cm. Knowing that, we could simply square one of the side lengths to find the area:

8² = 64 cm²

To find the perimeter, just add all the side lengths. There are four sides to a square so we can just multiply the side length by 4:

8 · 4 = 32 cm

Area :64 cm perimeter :32 cm

Apply the distributive property to factor out the greatest common factor.
55+35​

Answers

Answer:

Step-by-step explanation:

We have,

55 + 35

To find, the distributive property to factor out the greatest common factor,

55 + 35 = ?

We know that,

The distributive property of multiplycation,

The factors of 55 = 1, 5, 11 and 55 and

The factors of 35 = 1, 5, 7 and 35

The greatest common factor of 55 and 35 = 5

Using distributive property of multiplycation,

The greatest common factor = 5

Hence, the greatest common factor of 55 and 35 is .

what is the slope of the line with the following equation? (y-3)= -4(x-5)

Answers

Answer:

slope = - 4

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 3 = - 4(x - 5) ← is in point- slope form

with slope m = - 4

Answer:

-4

Step-by-step explanation:

First express it in the form of y=mx+b where m is the slope and b is the y-intercept

y-3=-4x+20

y=-4x+20+3

y=-4x+23 then m=-4 which is the slope

It is likely because if the bag holds red and green grapes then its not impossible to get a green grape because there are green grapes in the bag. It is not unlikly because there are 11/15 green grapes there, so there are more green grapes than red. But its still not certain that you will get a green grape, remember there are still quite a few red grapes too! So you would likely get a green grape.
