What is the reflections over the x- and y-axes

1 answer:

5 0

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).

What is 12.95p=44 simplified to its lowest value

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

What is 12.95p=44 simplified to its lowest value?

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$\sf \: 12.95p = 44$

Divide both sides by 12.95.

$\sf \: p=\frac{44}{12.95} \\$

Expand 44/12.95 by multiplying both the numerator and denominator by 100.

$\sf \: p=\frac{4400}{1295} \\$

Reduce the fraction 4400/1295 to its lowest terms by extracting and cancelling out 5.

$\boxed{ \boxed{ \bf p = \frac{880}{259} = 3\frac{103}{259} \approx 3.39}}$

Write 93/50 as a percentage.

elena55 [62]

Answer: 186%

To get this simply divide 93 into 50 (you will get 1.86 which you can convert to the percentage 186%). An even easier way is to multiply 93 by two (186) since 50% times 2 is 100%. Hope this helps!

Mahmoud is working out the height, h metres, of a tower

melomori [17]

Answer:

24.72 m

11.53 m

Step-by-step explanation:

Horizontal distance AB can be obtained from △ABC

From trigonometry :

Sin18° = opposite / hypotenus

Sin18° = AB / 80

AB = 0.3090169 * 80

AB = 24.72 m

The height BT, of tower from △ABT

From trigonometry :

Tan25° = opposite / Adjacent

Tan25° = h / 24.72m

h = Tan25 * 24.72

h = 11.527

h = 11.53 m

Hence, height of tower BT = 11.53 m

(a) n is an integer.

Nina [5.8K]

The possible integer values of n are:

-1, 0, 1 , 2 , and 3.

-1 to 3 are all greater than -2.

3 is the maximum since 3 is the greatest number where n is equal to it or lesser than it.

Solving the inequality: 3y - 4 > 17

3y - 4 > 17

Add 4 to both sides to move it.

3y > 17 + 4

3y > 21

Divide both sides by 3 to get the value of y.

3y/3 > 21

y > 7

The sign does not change since we did not divide or multiply by a negative.

Therefore, y is greater than 7.
