A retangle has a perimeter (p) of 58 inches. The length (L) is one more than 3 times the width (W)

worty [1.4K]

The rectangle has a perimeter P of 58 inches.The length l is one more than 3 times the width w.write and solve a system of linear equations to find the length and width of the rectangle?

Answer:

Length(L)=22 inches

Width(W) = 7 inches

Step-by-step explanation:

GIven:-

Perimeter (p)=58 inches,

Length(L)= one more than 3 times the width(W)

Let, W=x ---------------------------------(equation 1

$L=3x+1$ -----------------------(equation 2)

Here x is unknown and to find the Width(W) we have to find the value of x.

Now,

Perimeter of rectangle(p) = 2 times length(L) + 2 times width(W)

$p=2L+2W$

$p=2(3x+1)+2x$ ----------------(from equation 1)

$58=6x+2+2x$ ----------------(given p=58 inches)

$58=8x+2$

$8x=58-2$

$8x=56$

$x=\frac{56}{8}$

$x=7$ ----------------------(equation 3)

Now substituting the value of equation 3 in equation 2.

$L=3x+1$

$L=(3\times 7)+1$

$L=21+1$

$L=22$

$L=22 inches$

as, $W=x$ -----------------------(from equation 1)

$W=7$ inches -------------------(equation 3)

Therefore, Length(L) = 22 inches and Width(W) = 7 inches.

Bottle A contains 4 ounces of water, which is 25% of the amount of water in Bottle B. How much water is there in Bottle B?

sveticcg [70]

Answer:

B=16 ounces

C=24 ounces

B=1/0.75=133%

Step-by-step explanation:

we have that

A≡0.25B (25%), if A=4 ounces then B=4/0.25 = 16 ounces

C=1.5B (150%), if B=16 ounces then C=1.5*(16 ounces) = 24 ounces

D≡xB (?%), if D=12 ounces then x=12/16 = 0.75 ≡ 75%, but xB≡D ⇒ B≡D/x →

B≡12(1/0.75)= B=12*(1.333)→ B≅133%D

The formula for the volume of a right circular cone, V, is given below, where r represents the radius of the base of the cone an

Mrrafil [7]

Answer:

$r=\sqrt{\frac{3V}{(\pi h)}}$

Step-by-step explanation:

we know that

The volume of a right circular cone is equal to

$V=\frac{1}{3}\pi r^{2}h$

where

r is the radius of the base of the cone

h is the height

Solve for r-----> That means, isolate the variable r

so

step 1

Multiply by 3 both sides

$3V=\pi r^{2}h$

step 2

Divide by $(\pi h)$ both sides

$\frac{3V}{(\pi h)}=r^{2}$

step 3

take square root boot sides

$r=\sqrt{\frac{3V}{(\pi h)}}$

Geraldine has 8 cups of sugar. She uses 6 3/5 cups to make a large cake. How many cups of sugar does she have left?

Inga [223]

Answer:

$1\frac{2}{5}$

Step-by-step explanation:

remaining cups = total cups - used caps

let remaining cups be = x

total cups = y = 8

used cups = z= $6\frac{3}{5}$

Hence x = y-z

x = 8 - $6\frac{3}{5}$

= $\frac{8}{1}$ - $\frac{33}{5}$ = $\frac{40-33}{5}$ = $\frac{7}{5}$ = $1\frac{2}{5}$

x= $1\frac{2}{5}$

Remaining cups = $1\frac{2}{5}$
