Statement:

PQRS is a rhombus with PQ = (9b - 5) and QR = (3b - 0.8) meters. S is the midpoint of RT.

To find out:

The length of RT.

Solution:

There is a property of a rhombus that all sides of the rhombus are equal.

So, PQ = QR = RS.

Therefore, 9b - 5 = 3b - 0.8
or, 9b - 3b = -0.8 + 5
or, 6b = 4.2
or, b = 4.2 ÷ 6 = 0.7 m

Therefore, the length of RS
= 9b - 5
= 9(0.7) - 5 m
= 6.3 - 5 m
= 1.3 m

S is the midpoint of RT.
Hence, TS = RS = 1.3 m

Therefore, the measure of RT
= TS + RS
= (1.3 + 1.3) m
= 2.6 m

Answer:

RT = 2.6 meters

Answer: 2.6

Step-by-step explanation:

PQ = QR (because it’s a rhombus), so

9b - 5 = 3b - 0.8

b = 0.7

And RS = PQ (again because rhombus), so RS = 9b - 5 = 1.3. Since RT is twice RS, we have

RT = 2(1.3) = 2.6.

The width of a rectangular prism is six times its length. The height is five times its length. If its length is m units, what is

I am Lyosha [343]

Answer:

$30m^3$ cubic units.

Step-by-step explanation:

Let m represent length of the rectangular prism.

We have been given that the width of a rectangular prism is six times its length, so width of the prism would be $6m$ .

We are also told that the height is five times its length, so height of the prism would be $5m$ .

We know that volume of rectangular prism is height times width times length.

$\text{Volume of rectangular prism}=lwh$

$\text{Volume of rectangular prism}=m\cdot 6m\cdot 5m$

$\text{Volume of rectangular prism}=30m^3$

Therefore, the volume of the given rectangular prism would be $30m^3$ cubic units.

A single die is rolled. Find the probability of each of the following events :

IceJOKER [234]

$\frac{1}{2}$ and $\frac{1}{3}$

There are 6 possible outcomes when rolling a die, 1, 2, 3, 4 , 5, 6

numbers less than 4 are 1, 2, 3

P( number less than 4 ) = $\frac{3}{6}$ = $\frac{1}{2}$

numbers greater than 4 are 5, 6

P( number greater than 4 ) = $\frac{2}{6}$ = $\frac{1}{3}$

A force of 50 pounds is exerted at an angle of 80 with the horizontal. What is its horizontal component?

Shalnov [3]

Answer:

Option A is the correct answer.

Explanation:

Any vector can be resolved in to two components. Horizontal component and vertical component.

Consider a vector F which is at angle θ⁰ to the horizontal, we can resolve this vector in to two.

Horizontal component = F cos θ

Vertical component = F sin θ

Here we have Force , F = 50 pounds

Angle with horizontal = 80°

Horizontal component = F cos θ = 50* cos 80 = 8.68 pounds

≅ 9 lb.

Option A is the correct answer.
