Step-by-step explanation:

Step 1: Subtract the first part

$1\frac{1}{2} - \frac{1}{4}$

$\frac{3}{2} - \frac{1}{4}$

$\frac{6}{4}-\frac{1}{4}$

$\frac{5}{4}$

Step 2: Multiply both to get how much the brother drank

PilotLPTM [1.2K]

Answer:

"Can't be determined"

Step-by-step explanation:

From the triangles given in the picture,

Given:

m∠A = m∠C

m∠B = m∠D

But for the congruence of these triangles third condition is not given.

Therefore, congruence of these triangles can not be determined.

So the answer is "Can't be determined"

Find the equation of the straight line which passes through the point (-1,3) and make intercept on x - axis as thrice that on y

Triss [41]

Answer:

$y = -\frac{1}{3}x + \frac{8}{3}$

Step-by-step explanation:

Given

$(x_1,y_1) = (-1,3)$

$Intercept\ on\ x-axis = Intercept\ on\ y-axis.$

Required

Determine the equation

First, we calculate the intercepts using:

$\frac{x}{a} + \frac{y}{b} = 1$

Where

b = Intercept on y axis.

a = Intercept on x axis.

From the question:

$a = 3b$

The equation becomes:

$\frac{x}{3b} + \frac{y}{b} = 1$

Multiply through by 3b

$x + 3y = 3b$

We have: $(x_1,y_1) = (-1,3)$

So:

$-1 + 3 * 3 = 3b$

$8 = 3b$

Make b the subject

$b = \frac{8}{3}$

Substitute $b = \frac{8}{3}$ in $x + 3y = 3b$ to get the equation

$x + 3y = 3 * \frac{8}{3}$

$x + 3y = 8$

Make 3y the subject

$3y = -x + 8$

Make y the subject

$y = -\frac{1}{3}x + \frac{8}{3}$

The length of a train car is 50.6 feet this is baffling 8 feet less than six times the width what is the width

hram777 [196]

Answer:

the width is 9 23/30 feet ≈ 9.767 ft

Step-by-step explanation:

Let w represent the width of the train car. Then 6 times the width is 6w, and 8 ft less than that is (6w-8). We are told this amount is 50.6 feet, so we have ...

6w -8 = 50.6

6w = 58.6 . . . . . . . add 8; next divide by 6

58.6/6 = w = 586/60 = 293/30 = 9 23/30 . . . . feet

This is a repeating decimal: 9.766666...

The width of the train car is 9 23/30 ft, about 9.77 ft.
