Answer:

x = 20

Step-by-step explanation:

first, you would take all of the angles and add them up to 180

2x+40+100=180

second, we combine like terms

2x+140=180

third, we solve for x

2x+140=180

    -140  -140

2x=40

x=20

i hope this helps!

Answer:

X=20

Step-by-step explanation:

the total angle degree of a triangle is always 180 so we have two point 100 and 40 add those and you get 140 so you have 40 left but that angle says 2 X so 2x is 40 so ÷ 2 to get 1x which is 20

Answer:

Solve for  x  by simplifying both sides of the equation, then isolating the variable.

x  =  − 6

Answer:

d. 17.5 and 28 units

Step-by-step explanation:

An area of a rectangle is length times width. 8x times 5x = 40x^2. 40x^2 is eqaul to 500. After dividing by 40 and taking the square root of the quotient, x is approximately 3.54. 5 times 3.54 and 8 times 3.54 will yield approximately 17.5 and 28 units.

Answer:

p=-1

Step-by-step explanation:

3x^2+6x-6=0

Add 6 on both sides

3x^2+6x=6

Divide through by 3

x^2+2x=2

Complete the square on the right side

If a quadratic equation is given by

ax^2+bx+c=0

then c=b/2

x^2+2x=2

c=2/2=1

Adding 1 on both sides

x^2+2x+1=2+1

x^2+x+x+1=3

Combining

x(x+1)+1(x+1)=3

(x+1)(x+1)=3

(x+1)^2=3

p=-1

Answer: D) 968

Step-by-step explanation:

48 x 24 = 1152 (total pencils)

8 x 23 = 184 (total pencils given to all 23 students)

1152 - 184 = 968 (extra pencils)

Answer:

The answer is 968

Step-by-step explanation:

First we know that there are 48 boxes with 24 pencils in each box so we must multiply (48x24=1,152) as shown this gives us 1,152 pencils. We also know that that teacher has 28 students and wants to give  them each 8 pencils, so we multiply again (28x8=184). Now we know that Mrs. Patterson has to give 184 of her pencils to her students, so we subtract 184 from the total amount of pencils she has (1152-184=968) Which gives us the answer, 968.

Answer:

Kristi

Step-by-step explanation:

The formula for Simple Interest =

Principal × Rate × Time

For Kristi

Kristi invests $3,000 at a 7.25% annual simple interest rate,

Principal = $3000

Rate = 7.25% = 0.0725

Time = 1

Simple interest = $3000 × 0.0725 × 1

= $217.5

For Kari

Her sister Kari invests $3,200 at a 6.25% annual simple interest rate.

Principal = $3200

Rate = 6.25% = 0.0625

Time = 1

Simple interest = $3200 × 0.0625 × 1

= $200

From the above calculation, we can see that: Kristi will earn the greater amount of interest after one year

Ok so you will just need to subtract 65.45-35.5 and get your answer.

Ps could have used a calculator.

Answer:

The answer is actually 0

Step-by-step explanation:

Let's solve your equation step-by-step.

t−(−29)=29

Step 1: Simplify both sides of the equation.

t+29=29

Step 2: Subtract 29 from both sides.

t+29−29=29−29

t=0

So t = 0

45 55 60

Step-by-step explanation:

45% 55 0.6

The correct ascending order of  0.6, 45%, and 11/20 is  45% < 11/10 < 0.6.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

We know decimals and fractions can be converted into percentages by multiplying by 100.

So, The percentage equivalent of 0.6 is,

= 0.6×100.

= 60%.

And, The percentage equivalent of 11/20 is,

= (11/20)×100.

= 1100/20.

= 110/2.

= 55.5%.

So, The correct ascending order is 45% < 11/10 < 0.6.

Answer:

(0, -4)

Step-by-step explanation:

Given the inequality expression

y>−2x+y≤4

This can be splitted into

y>−2x+y .... 1

and -2x+y≤4 .... 2

From1;

y>−2x+y

y - y >−2x

0 >−2x

-2x < 0

x > 0/-2

x>0

Substitute x = 0 into 2

-2(0)+ y ≤4

y≤4

Hence the solution is (0, -4)

Answer:

B. 2,3,4

Step-by-step explanation:

Using the Pythagorean Theorem:

A. 1^2+3^2=(sqrt10^2)

B. 2^2+3^2not equal to 4^2

C. 3^3+4^2=5^2

D. 8^2+15^2=17^2

The set of numbers {2, 3, 4} could not represent the lengths of the sides of a right triangles.

The correct option is an option (B).

"For integers a, b, c if a² + b² = c², then these integers are called as Pythagorean triples they can be denoted as (a, b, c)"

"For a right triangle,

c² = a² + b², where c is the hypotenuse and a, b are any two sides of the right triangle."

"It is the lonest side of the right triangle."

For given example,

We need to find the set of numbers that could not represent the lengths of the sides of a right triangles.

If the set of numbers is not Pythagorean triple then it would not represent the lengths of the sides of a right triangles.

A) {1, 3, √10}

let a = 1, b = 3, c = √10

⇒ c² = (√10)²

⇒ c² = 10

Consider, a² + b² = 1² + 3²

⇒ a² + b² = 1 + 9

⇒ a² + b² = 10

⇒ a² + b² = c²

This means, these numbers are Pythagorean triple.

So, these numbers represents the lengths of the sides of the right triangle with hypotenuse √10 unit and other two sides are 1 unit and 3 units.

B) {2 ,3, 4}

let a = 2, b = 3, c = 4

⇒ c² = (4)²

⇒ c² = 16

Consider, a² + b² = 2² + 3²

⇒ a² + b² = 4 + 9

⇒ a² + b² = 13

⇒ a² + b² ≠ c²

This means, these numbers are not a Pythagorean triple.

So, these numbers does not represent the lengths of the sides of the right triangle.

C) {3, 4, 5}

let a = 3, b = 4, c = 5

⇒ c² = (5)²

⇒ c² = 25

Consider, a² + b² = 3² + 4²

⇒ a² + b² = 9 + 16

⇒ a² + b² = 25

⇒ a² + b² = c²

This means, these numbers are Pythagorean triple.

Hence, these numbers represents the lengths of the sides of the right triangle with hypotenuse 5 units and other two sides are 3 units and 4 units.

D) {8, 15, 17}

let a = 8, b = 15, c = 17

⇒ c² = (17)²

⇒ c² = 289

Consider, a² + b² = 8² + 15²

⇒ a² + b² = 64 + 225

⇒ a² + b² = 289

⇒ a² + b² = c²

This means, these numbers are Pythagorean triple.

So, these numbers represents the lengths of the sides of the right triangle with hypotenuse 17 units and other two sides are 8 units and 15 units.

Therefore, the set of numbers {2, 3, 4} could not represent the lengths of the sides of a right triangles.

The correct option is an option (B).

Answer:

The 2nd one

Step-by-step explanation:

The ratio of the sides of 45-45-90 triangles is a:a:a[tex]\sqrt{2}[/tex]. 9 would be the side that is equal to a[tex]\sqrt{2}[/tex], so to find what a is you have to do 9 divided by [tex]\sqrt{2}[/tex].
