Identify the graph of y>−4

Answer: 2

Step-by-step explanation:

Using the Z rule, we get the angle of DCE is 2x + 53

The angle DEC is a right angle as the diagonals of a rhombus always make a right angle

So we get the equation

3x + 7 + 2x + 53 + 90 = 180

5x = 10

x = 2

Find the least common multiple of the denominators of the fractions. Write equivalent fractions that have the least common multiple as the denominator.

Answer:

quadrilateral

Step-by-step explanation:

Answer:

<ABC=90° <OCB=36° <OAB=54°

Step-by-step explanation:

<ABC=90°

<ocb= half of aob

<oab + <abc+<ocb=180°(triangle abc)

Answer:

a) ∠OAB = 54°

b) ∠OCB = 36°

c) ∠ABC = 90°

Step-by-step explanation:

a)

If O is the center of the circle, then OA and OB are both the radius.  Therefore, OA = OB

This means that ΔAOB is an isosceles triangle, as is has two sides of equal length (OA and OB).  

The angle between the equal sides (∠AOB) is called the vertex angle.  The side opposite the vertex angle (AB) is called the base and base angles are equal. Therefore, ∠OAB = ∠OBA

Given:

⇒ ∠OAB + ∠OBA + ∠AOB = 180

⇒ ∠OAB + ∠OBA + 72 = 180

⇒ ∠OAB + ∠OBA = 108

⇒ ∠OAB = 108 ÷ 2 = 54°

b)

Again, we can see that OB and OC are both the radius, so OB = OC.  This means that ΔBOC is also an isosceles triangle, with ∠BOC as the vertex and BC as the base.

Calculate ∠BOC:

Given:

⇒ ∠AOB + ∠BOC = 180

⇒  72 + ∠BOC = 180

⇒ ∠BOC = 108°

Calculate ∠OCB:

Given:

⇒ ∠OBC + ∠OCB + ∠BOC  = 180

⇒ ∠OBC + ∠OCB + 108  = 180

⇒ ∠OBC + ∠OCB  = 72

⇒ ∠OCB  = 72 ÷ 2 = 36°

c)

Thales's theorem is a special case of the inscribed angle theorem and states that:

Given that AC is the diameter of this circle, and points A, B and C are on the circle, then ∠ABC = 90°

Answer:

$2,871.00

Step-by-step explanation:

Calculation:

First, converting R percent to r a decimal

r = R/100 = 8%/100 = 0.08 per year.

Solving our equation:

A = 1595(1 + (0.08 × 10)) = 2871

A = $2,871.00

The total amount accrued, principal plus interest, from simple interest on a principal of $1,595.00 at a rate of 8% per year for 10 years is $2,871.00.

Answer:

4-(3x+3)=4x

4-3x-3=4x

4-3=4x+3x

1=7x

x=1/7

or

4-(3x+3)=4x

4-3x-3=4x

-3x-4x=-4+3

-7x=-1

x=-1/-7

-/-=+

so -1/-7 it equal to 1/7

you dont want negative x

x=1/7

Answer:

1/7

Step-by-step explanation:

Take your equation: 4-(3x+3)=4x

Then, use the distributive property to carry out the negative sign, so you get   4-3x-3=4x

Add 3x to both sides to get:  4-3=4x+3x

Add like terms together to get:  1=7x

Flip the sides to get: 7x=1

Divide by 7 on both sides to get 7x/7=1/7

Simplify to get: x=1/7

Answer:

[tex]x\geq 15[/tex]

Step-by-step explanation:

Samuel wants at least 15 grams

Let's expand on "at least 15"

It means that Samuel wants no less than 15, but 15 or more

It could be 16, but not 14

To create an inequality, 15 or more can be written as [tex]x\geq 15[/tex] (x is 15 more more)

The answer is [tex]x\geq 15[/tex]

3y = 5

6 = 2x + 2

x = 2, y = 5/3

2x - 2 = 2   ←

Answer:

y = - 4

Step-by-step explanation:

3y = 2x - 6 ................. (1)

4x + 3y = - 24 ........... (2)

(1)  ---->  (2)

4x + ( 2x - 6 ) = - 24

6x - 6 = - 24

x - 1 = - 4

x = - 3

3y = 2 ( - 3 ) - 6

3y = - 12

y = - 4

( - 3 , - 4 )

Answer:

1) x = 208     2) n = 28

Hope this helps! Have a great day!!

Step-by-step explanation:

1)

x  -  72  =  136

    +  72      +72

x             =    208

2)

 n  -  10  =  13  +  5

 n  -  10  =  18

       +10       +10

        n      =  28

Answer:

D

Step-by-step explanation:

substitute the x- coordinate of each point into the equation and if the value obtained is equal to the y- coordinate then the point makes the equation true.

A (- 3, - 1 )

y = 3(- 3) = - 9 ≠ - 1 ← false

B (3, 1 )

y = 3(3) = 9 ≠ 1 ← false

C (6, 4 )

y = 3(6) = 18 ≠ 4 ← false

D (2, 6 )

y = 3(2) = 6 ← true

Answer:

-You should already be familiar with algebra and geometry before learning trigonometry. From algebra, you should be comfortable with manipulating algebraic expressions and solving equations. From geometry, you should know about similar triangles, the Pythagorean theorem, and a few other things, but not a great deal.

-Measure the lengths of the sides of sets of similar right angled triangles and find the ratio of sides.

-Investigate the relationship between these ratios and the angle size.

-Use calculators or tables to find the sine, cosine and tangent of angles.

Step-by-step explanation:

basic knowledge i guess

Before beginning trigonometry, you need be comfortable with algebra and geometry. You should be comfortable handling algebraic expressions and solving problems after studying algebra. You should know about similar triangles, the Pythagorean theorem, and a few other things from geometry, but not much else. Students can use trigonometry to calculate the precise angle of a triangle's sides, the distance between distinct points on a triangle, and other information that is useful in a number of situations. Trigonometry is an essential component of ICSE Class 10 Mathematics since it combines memorization, conceptual knowledge, and problem-solving abilities. Because many of the earth's natural formations resemble triangles, it aids children in their comprehension of the globe.

Answer:

145 Hamburgers were sold on Saturday

Step-by-step explanation:

435/3=145

145 x 2=290

290+145=435

Answer:

145 hamburgers

290 cheeseburgers

Step-by-step explanation:

let 'h' = # of hamburgers

let 'c' = # of cheeseburgers

h + c = 435

c = 2h

substitute '2h' for 'c' in the first equation:

h + 2h = 435

3h = 435

h = 145

c = 2(145) = 290

Step-by-step explanation:

26 liters of yellow paint need to be added for the ratio of green paint to yellow paint to be 1:6.

An equation is an expression that shows the relationship between two or more variables and numbers.

From the question:

Amount of green paint = (3/8) * 16 = 6 liters

For the ratio of green paint to yellow paint to be 1:6, let y represent the number of yellow paint to be added.

6 = (1/7) * (16 + y)

16 + y = 42

y = 26

26 liters of yellow paint need to be added for the ratio of green paint to yellow paint to be 1:6.
