Answers

Answer 1

Answer:

Answer:

$(7)/(4)$

Step-by-step explanation:

Here is the complete question: 28 elementary schools to 16 middle schools, write the ratio in simplest form.

Given ratio= elementary schools: middle schools:: 28:16

The ratio can be written as $(28)/(16)$

Now to write $(28)/(16)$ into simplest form, we need to divide both numerator and denominator by 4.

∴ elementary schools: middle schools= $((28)/(4) )/((16)/(4) )$

Hence, we get simplest ratio of elementary schools to middle schools= $(7)/(4)$

Use the squared identities to simplify sin^2x cos^2x

Answers

Answer:

$(1-cos^2(2x))/(4)$

Step-by-step explanation:

We have the following expression

$sin^2x *cos^2x$

Whe know that:

$sin^2(x) = (1-cos(2x))/(2)\n\ncos^2(x)=(1+cos(2x))/(2)$

Now replace these equations in the main expression and simplify

$((1-cos(2x))/(2))*((1+cos(2x))/(2))$

$(((1-cos(2x))(1+cos(2x)))/(4))$

Apply the following property

$(a + b) (a-b) = a ^ 2 -b ^ 2$

Then

$(((1-cos(2x))(1+cos(2x)))/(4))=(1^2-cos^2(2x))/(4)$

Finally:

$(((1-cos(2x))(1+cos(2x)))/(4))=(1-cos^2(2x))/(4)$

Scott makes a scale drawing of a rectangular park. He uses the scale 5 centimeters: 3 meters. The length of his drawing is 20 centimeters and the width is 15 centimeters. What is the area of the park

Answers

Answer:

The area of the park is $108\ m^(2)$

Step-by-step explanation:

we know that

The scale drawing is $(5)/(3)(cm)/(m)$

step 1

Find the actual length of the rectangular park

Divide the length in the drawing by the scale drawing

$20/(5/3)=12\ m$

step 2

Find the actual width of the rectangular park

Divide the width in the drawing by the scale drawing

$15/(5/3)=9\ m$

step 3

Find the area of the park

$A=(12)(9)=108\ m^(2)$

The inequality ∣60∣≤∣−60∣ holds true. This is because the absolute value of both 60 and -60 is equal to 60.

The expression ∣60∣≤∣−60∣ can be evaluated by calculating the absolute values on both sides. The absolute value of 60 is 60, and the absolute value of -60 is also 60. So, ∣60∣=∣−60∣=60.

Since 60 is equal to 60, the inequality ∣60∣≤∣−60∣ is true. This inequality states that the absolute value of 60 is less than or equal to the absolute value of -60. In this case, since both absolute values are equal, the statement is true. The absolute value function essentially removes the negative sign from a negative number, making it positive, and in this case, the absolute values of 60 and -60 are indeed the same, resulting in a true inequality.
