The ratio of width to length of a rectangle is 7:10.The width of the rectangle is 91 cm.

kvasek [131]

Answer:

Length= 130 cm

For, Width= 91 cm

Step-by-step explanation:

Ratio of the width to the length of the rectangle = 7:10

Width of the rectangle= 91 cm

$\frac{Width}{Length} =\frac{7}{10}$

As, Width = 91 cm

$\frac{91}{Length} =\frac{7}{10}$

On, Cross multiplication the fraction:

$91*10=7*Length$

$7*Length=910$

Dividing by '7' both the sides:

$Length=\frac{910}{7}\\\\ Length=130cm$

The ages of four sisters are consecutive even integers. Two times the age of the youngest sister exceeds the oldest sister's age

S_A_V [24]

Alright, lets get started.

The ages of all four sisters will be = x, x+2, x+4, x+6

As per given in question, two times of youngest sister age exceeds the oldest sister age by 30 means

$2x - 30 = (x+6)$

Simplifying the equation

$2x - (x+6) = 30$

$2x - x - 6 = 30$

$x = 36$

So this is the age of youngest sister.

So, age of oldest sister will be $x + 6 = 36 + 6 = 42$

Hene the age of oldest sister is 42 years. : Answer

Hope it will help :)

Geometry please help!

Answer:

x = 3

Step-by-step explanation:

Angle S and Angle T are consecutive interior angles. Therefore, we know that T + S = 180°.

First, we need to solve for T, and since angles S and T are consecutive interior angles, we know that T + S = 180°. If we reorganize the equation to include the things we know (S = 105°), then we get 180° - 105° = 75°. So T is 75°.

Now, we use T = 75° and the information given to us in the picture to set up an equation. 75 = 24x + 3. Now, we can find x by isolating it. Do this by:

1) Subtracting 3 from both sides to give you 72 = 24x. We do this to get rid of the 3 from the "x side", but we must also do it to the other to keep the equation true. This moves the 3 from the "x side" to the other since we're trying to isolate x.

2) Divide 24 by both sides to get 3 = x. We use the same logic as we did for 3, except this time we divide since that's the opposite of multiplying.

In conclusion, x = 3.
