13. Higher Order Thinking Eve and Gerard

Mathematics
1 answer:
ella [17]3 years ago
6 0

Answer:

Gerard's blue section is larger.

Step-by-step explanation:

Eve  divided her half into 6 equal sections and painted one section blue.

So, the blue-painted part will be of size (\frac{1}{2} \times \frac{1}{6}) = \frac{1}{12} part of the whole poster.

Again, Gerard  divided her half into 5 equal sections and painted one section blue.

So, the blue-painted part will be of size (\frac{1}{2} \times \frac{1}{5}) = \frac{1}{10} part of the whole poster.

Now, since 12 > 10, so, \frac{1}{12} < \frac{1}{10}

Therefore, Gerard's blue section is larger. (Answer)

Solve this equation:
jek_recluse [69]

Answer:

b. All real numbers

Step-by-step explanation:

Simplify:

  • 5(x-2) = (15x+6)/(3) - 12
  • 5x - 10 = 5x + 2 - 12
  • 5x - 10 = 5x - 10
  • -10 = -10
  • 0 = 0

Since both sides are equal to each other, any value of x makes this equation true.

Answer:

Height of the cliff = 13.66 m

Step-by-step explanation:

Let the height of the cliff is 'x' m and distance between the base of the cliff and the boat is 'y' m.

From right triangle AOC,

tan 30° = \frac{\text{Opposite triangle}}{\text{Adjacent side}}

\frac{1}{\sqrt{3}}=\frac{x}{y}

y = x\sqrt{3} ------(1)

From right angle triangle BOC,

tan 45° = \frac{x}{y-10}

1=\frac{x}{y-10}

x = y - 10

y = x + 10 -------(2)

From equations (1) and (2),

x\sqrt{3}=x+10

x(\sqrt{3}-1)=10

x=\frac{10}{\sqrt{3}-1 }

x = 13.66 m

Therefore, height of the cliff is 13.66 m.

Answers with explanations:

Problem 2-
First we have to insert our numbers into the equation. So we would have
l2l-l-7l
The ll bars mean to find the absolute value. Absolute value is how many spaces it is between that number and zero. So we can simply this to
2-7=-5

Problem 3-
First, we have to insert our numbers into the problem.
2(-2)^3(3)
Using PEMDAS or order of operations, we solve the exponent first and simplify from there
2(-8)(3)
(-16)(3)
(-48)
The answer is -48

Problem 4-
Again, we have to input the numbers into the equation.
(4^2-4(-3))/2
(16-4(-3))/2
(16+12)/2
(28)/2
14
The answer is 14

Problem 5-
(3)(-1)-(-1^2)
(3)(-1)-(1)
-3-1
-4
The answer is -4

Problem 7-
l-3-4l- -3^2
l-3-4l- +9
l-7| - +9
7-+9
-2
The answer is -2

Problem 8-
3(-3)^2-4|-3|+6
3(9)-4|-3|+6
27-4|-3|+6
27-12+6
