11. Find the coordinates of the point located six units behind the yz- plane, seven units to the right of the xz - plane, and ei

Alexxandr [17]

Answer: I think

Step-by-step explanation:Let the coordinate of the point be (x,y,z). Since the point is located 3 units behind the YZ− plane, 4 units to the right of XZ− plane and 5 units above the XY−plane ,x=−3,y=4 and z=5 Hence, coordinates of the required points are (−3,4,5)

The ratio of Alani's height is Baahir's height is 5:7, The ratio of Baahir's height to Conner's height is 4:3. What is the ratio

Oduvanchick [21]

General Idea:

When you have ratio a:b and b:c, to find the ratio of a:c, we need to multiply a:b with b:c. When multiplying fractions we need to multiply numerator with numerator and denominator with denominator. Then cancelling common terms we get the ratio a:c like shown below:

$\frac{a}{b}\cdot \frac{b}{c} =\frac{a \cdot b}{b \cdot c} \\ Cancel \; common\;factor\;b\;in\;numerator\;and\;denominator\\ \\ \frac{a}{c} =a:c$

Applying the concept:

$\frac{5}{7} \cdot \frac{4}{3} =\frac{5 \cdot 4}{7 \cdot 3} =\frac{20}{21}$

Conclusion:

Given that "The ratio of Alani's height is Baahir's height is 5:7, The ratio of Baahir's height to Conner's height is 4:3."

<u>The ratio of Alani's height to Conner's height is 20:21</u>

Find the following when a = -1, b = 2, c = -1/4<br> (4b - 3)/(2a) -1

Katena32 [7]

We substitute the given into the equation
given: a=-1, b=2, c= $\frac{-1}{4}$
=( $\frac{4b-3}{2a}$ -1
= $\frac{4(2)-3}{2(-1)}$ -1
= $\frac{8-3}{-2}$ -1
= $\frac{5}{-2}$ -1
to continue, we can either find a common denominator or change the fraction to decimal.
Fraction to Decimal:
$\frac{5}{-2}$ =-2.5
Equation=-2.5-1=-3.5
OR Common Denominator:
= $\frac{5}{-2}$ $\frac{-1}{1}$ × $\frac{-2}{-2}$ (denominator should be -2=common)
= $\frac{5}{-2}$ + $\frac{2}{-2}$
= $\frac{7}{-2}$
which also = to -3.5
