Help pls and explain I need 10 mins left

Answer:

for the first 2 neither one is a polygon because a polygon has straight sides and is closed connections were the first shape has an open connection and the second shape has a curved line. for question i believe is 48 and question 4 is 145.

explanation.

for the last 2 problems their total equal 360 so you just add up all the side then subtract the number you got by 360 and that's your answer. ex.) 120 +130+ 62=312. 360-312=48

Answer:

C. 15

Step-by-step explanation:

3 is 3/5 of 5

so x-6 should be 3/5 of x?

-6 would be 5/5 - 2/5

2/5 = 6

1/5 = 3

5/5 = x = 15

Step-by-step explanation:

▪AB = AC - EF

= 13 cm - 7 cm

= 6 cm

▪BD = CF - DE

= 16 - 8 cm

= 8 cm

BC = EF

perimeter = CF + EF + DE + AD + AB + BC

= 16 + 7 + 8 + 10 + 6 + 7

= 54 cm

Area of triangles = 1/2 × AB × BD

= 1/2 × 6 × 8

= 48/2

= 24 cm²

Area of rectangle = CF × EF

= 16 × 7

= 112 cm²

the total area = 24 + 112

= 136 cm²

Answer:

~1.93 seconds

Step-by-step explanation:

Set hight to 0:

0 = -16t^2 + 4t + 52

Rearrange:

16t^2 - 4t - 52

Solve using the quadratic formula: (Only use the positive result)

t = (1 + √209)/8

t ≈ 1.9321

Answer:

marcus

Lilian

Pamela

Step-by-step explanation:

simplefy the expresion wich will equal 58

Answer:

1) Marcus  2) Lillian  3) Pablo

Step-by-step explanation:

For these type of expressions you have to use "PEMDAS"

Parentheses              

Exponents

Multiplication

Division

Addition

Subtraction

(IT ALWAYS HAS TO GO FROM LEFT TO RIGHT)

1) Marcus  Why Marcus?

Because, Melanie added instead of dividing first.

Melanie:                Marcus:

8 x 7 + 14 / 7          8 x 7 + 14 / 7

56 + 14 / 7             56 + 14 / 7

70 / 7                     56 + 2  <---

10                           58

2) Lillian  Why Lillian?

Because, Landon Multiplied instead of dividing.

Lillian:                    Landon:

50 / ([tex]5^{2}[/tex] - 15) x 5     50 / ([tex]5^{2}[/tex] - 15) x 5

50 /  (10) -  5          50 / (10) - 5

5 x 5                      50 / 50  <---

25                          1

3) Pablo  Why Pablo?

Because, Pamela didn't follow the L --> R- (Left to Right) -Rule.

Pablo:                    Pamela:  

(12 + [tex]2^{2}[/tex]) / 4 x 5     (12 + [tex]2^{2}[/tex]) / 4 x 5

([tex]14^{2}[/tex]) / 4 x 5          (12 + 4) / 4 x 5 <---

196 / 4 x 5            16 / 4 x 5

49 x 5                   4 x 5

245                       20

Answer: A

Step-by-step explanation:

In a triangle, any two sides, when added up need to be greater the last side

Answer:

42

Step-by-step explanation:

Because of its shape I would imagine another flipped so it makes a square then solve for the square the divide.

7 x 12 =84

84÷2=42

Answer:

The Point estimate of the Population proportion  E = 0.039≅0.04

Step-by-step explanation:

Step(i):-

Given that the sample size 'n' = 992

  and                                     x = 570

The Population proportion

                                   [tex]p = \frac{x}{n} = \frac{570}{992} = 0.5745[/tex]

Step(ii):-

The point estimate of the Population proportion is determined by

[tex]E = 2.576 \frac{\sqrt{0.574(1-0.574)} }{\sqrt{992} }[/tex]

E = 0.039≅0.04

Final answer:-

The point estimate of the Population proportion  E = 0.039≅0.04
