A rectangle with 8 cm width and 3 cm length What is the perimeter and area of the rectangle?​

Answer:

Priya's age = 15

Amirah's age = 19

Shirley's age = 13

Step-by-step explanation:

Let x be the age of Priya.

According to the question,

Amirah's age = x + 4

Shirley's age = x - 2

Their sum is 47.

So,

x + 4 + x + x - 2 = 47

3x + 2 = 47

3x = 47 - 2

3x = 45

x = 45/3

x = 15

So,

Priya's age = 15

Amirah's age = 15 + 4 = 19

Shirley's age = 15 - 2 = 13

Answer:

Priya is 15 years old

Amirah is 19 years old and

Shirley is 13 years old

Step-by-step explanation:

let Amirah =x

let Priya = y

let Shirley = s

so we have

x= 4+y

s=y-2

x+y+s =47

we have x= 4+y

4+y+y+s=47

4+2y+s=47

2y+s=43

s-y=-2 (MULTIPLY BY NEGATIVE 1)

y-s =2

2y+s= 43

by solving simultaneously we get

3y= 45

y=15

x= 4+y

x=19

s=y-2

s= 13

so Priya is 15 years old

Amirah is 19 years old and

Shirley is 13 years old

Answer:

  (b)  m∠1 = 67.4°, m∠2 = 104.5°

Step-by-step explanation:

It is easiest to find angle 2 first, then make your answer selection based on that.

The exterior angle 121.8° is the sum of the remote interior angles 17.3° and angle 2. Then ...

  angle 2 = 121.8° -17.3° = 104.5° . . . . . . . matches the second choice

__

Angle 2 is an exterior angle of the top triangle. It, too, is the sum of the remote interior angles:

  104.5° = angle 1 + 37.1°

  angle 1 = 104.5° -37.1° = 67.4°

Answer:

C!

Step-by-step explanation:

m∠1 = 75.5°, m∠2 = 67.4°

Answer:

A

Step-by-step explanation:

first num is 15

ratio is 0.2

formula is a.r^n-1

Step-by-step explanation:

The Perimeter of Equilateral triangle = 60cm

According to the question,

To find the height of the triangle,

Perimeter of Equilateral triangle = Area of Equilateral triangle.

[tex]60 = \frac{ \sqrt{3} }{4} a {}^{2} \\ [/tex]

[tex]60 \times 4 = \sqrt{3a {}^{2} } [/tex]

[tex]a {}^{2} = 240 \sqrt{3} \\ [/tex]

[tex]a = 120 \sqrt{3} cm[/tex]

Answer:

x = 3, y = 5

or (3,5) in coordination point form.

Step-by-step explanation:

We are going to solve the system of equations by combining two equations. To do that, we isolate y-term.

[tex] \large{\begin{cases} 5x - y = 10 \\ 3x + y = 14 \end{cases}}[/tex]

Convert both equations to slope-intercept form.

[tex] \large{ \begin{cases} y = 5x - 10 \\ y = - 3x + 14 \end{cases}}[/tex]

Then combine both equations

[tex] \large{5x - 10 = - 3x + 14} \\ \large{5x + 3x = 10 + 14} \\ \large{8x = 24} \\ \large{x = 3}[/tex]

Substitute x = 3 in one of given equations. I will substitute x = 3 in y = 5x-10

[tex] \large{y = 5x - 10} \\ \large{y = 5(3) - 10} \\ \large{y = 15 - 10} \\ \large{y = 5}[/tex]

Hope this helps!

Answer:

∠x = 117°

Step-by-step explanation:

supplement of ∠101° = 79°

all triangle interior angles add up to 180°

180° - 79° - 38° = 63°

the supplementary angle to 63° is 117°

Answer:

m <1 = 64

m<2= 26

Step-by-step explanation:

the angle is 90 degree

therefore, <1 + <2 = 90

(x+51) + (2x) = 90

3x +51 = 90

3x = 39

x = 13

Answer:

You can combine like terms when they have the same variable, same category, or same coefficient. You CANNOT combine like terms when they have none of the attributes listed above. For example, you can combine 7x and 20x, just like you can combine 3 and 4, but you can't combine 3x & 5(x^2), or 9x and 73.

Answer:

0.7

∴P(even no. or multiple of 3)

= 7/10

Answer:

7/10 or 70%

Step-by-step explanation:

1     no

2     yes

3     yes

4     yes

5     no

6     yes

7     no

8     yes

9     yes

10    yes

7/10 are even or multiples of 3, therefore you have a 70% chance of drawing one of them

Answer:

[tex] x = \dfrac{3}{2} [/tex]

Step-by-step explanation:

x^2-3x+9/4 =0​

Multiply both sides by 4 to get rid of the fraction.

4x^2 - 12x + 9 = 0

[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]

[tex] x = \dfrac{-(-12) \pm \sqrt{(-12)^2 - 4(4)(9)}}{2(4)} [/tex]

[tex] x = \dfrac{12 \pm \sqrt{144 - 144}}{8} [/tex]

[tex] x = \dfrac{12}{8} [/tex]

[tex] x = \dfrac{3}{2} [/tex]

Answer:

BC = 36 ≅ (AQ+QD)

Step-by-step explanation:

1. Identify potential angles

∠Q≅90˚ so ∠B = 60˚ + 60˚ and ∠C = 30˚+30˚

2. Two isosoceles triangle

18=AB=AQ

18=CD=DQ

3. BC = AQ+QD

BC = 18+18

BC = 36

Answer: 25%

Step-by-step explanation:

Let's take our given numbers

20% you win both checkers and chess against your friend

30% you win against your friend in chess

Now we take both probability's 20% and 30%

We are know working with a probability out of 200%

Let's add 20% and 30%

20%+30%=50%

Now 50% of 200% is

25%

Answer:

b - 4 ≤ 15

b ≤ 19

Step-by-step explanation:

The statement "at most" typically means no more than, so the inequality sign would have to be "less than or equal to"

To solve for be all you would do is add 4 to both sides to get b by itself.

b - 4 ≤ 15

b - 4 + 4 ≤ 15 + 4

(-4 + 4 cancels itself out)

(15 + 4 = 19)

b ≤ 19
