HELP

Masja [62]

Answer:

He confused the height and diameter

Step-by-step explanation:

Given that,

The radius of the cylinder, r = 2.5 cm

Height of the cylinder, h = 24 cm

The volume of the cylinder is given by the formula as follows :

$V=\pi r^2 h\\\\=3.14\times (2.5)^2\times 24\\\\=471\ cm^3$

Vaughn is confused in diameter and the height of the cylinder. He takes radius as 12 cm and height as 5 cm which is wrong. Hence, the correct option is (a).

X-20 = y+20 2Y - 44 = X + 22

nordsb [41]

X-20 = Y+20........ X-Y = 20+20........

X-Y = 40

AND

2Y-44=X+22............. Y-X= 44+22

Y-X=66

NOW, LET'S FIND X AND Y FROM THESE TWO EQUATIONS....

X-Y =40

Y-X= 66

IF WE COLLECT ....... 2Y = 106 AND Y = 53

THEN, USE Y IN ANY EQUATIONS FOR FINDING X

X-53 = 40 ..... X= 53+40 .......... X= 93

X= 93

Y=53

Answer:

$\dfrac{5}{3}$

Step-by-step explanation:

To find the gradient (slope) of the given linear relation, use arithmetic operations to isolate y:

Given relation:

$3y-5x=10$

Add 5x to both sides:

$\implies 3y-5x+5x=10+5x$

$\implies 3y=5x+10$

Divide both sides by 3:

$\implies \dfrac{3y}{3}=\dfrac{5}{3}x+\dfrac{10}{3}$

$\implies y=\dfrac{5}{3}x+\dfrac{10}{3}$

Slope-intercept form of a linear equation

$y = mx+b$

where:

m is the slope (gradient)
b is the y-intercept

Comparing the rewritten equation with the slope-intercept formula, the gradient (slope) of the given linear relation is ⁵/₃.
