Step-by-step explanation:

Split the figure into 2 parts, triangle and rectangle (I believe you know what I'm talking about)

area of triangle = 1/2 x 20 x (16-7) = 90cm^2

area of rectangle = 20 x 7 = 140cm^2

total area = 90 + 140 = 230cm^2

In rhombus MOTH, angle HTM=(5x+6) degrees. If angle HMO=(12x-6)degrees, what is angle HMO?
forsale [732]

Answer:

m∠HMO=102°

Step-by-step explanation:

we know that

In a Rhombus the diagonals bisect the angles and opposite angles are equal

In this problem

Angles HMO and HTO are opposite angles

m∠HMO=m∠HTO

m∠HTM=(1/2)m∠HMO ----> because the diagonals bisect the angles and opposite angles are congruent

substitute the values

(5x+6)\°=(1/2)(12x-6)\°

solve for x

10x+12=12x-6\\12x-10x=12+6\\2x=18\\x=9

<em>Find the measure of angle HMO</em>

m∠HMO=(12x-6)°

substitute the value of x

m∠HMO=(12(9)-6)=102°

see the attached figure to better understand the problem

Bethany sells roses and petunias. The expression 3r+2.5p gives the cost (in dollars) of roses(r) and petunias(p). What is the co
aksik [14]

Answer:

Total cost = 16

Step-by-step explanation:

In the equation of cost, we can see that each rose costs 3 and each petunia costs 2.5.

To find the total cost of two roses and four petunias, we can use the values r = 2 and p = 4 in the equation given, so:

Total cost = 3r + 2.5p = 3*2 + 2.5*4 = 6 + 10 = 16

So the total cost of two roses and four petunias is 16.

For a moving object, the force acting on the object varies directly with the objects acceleration. When a force of 35 N acts on
Genrish500 [490]
<h3>Answer:  3 m/s^2</h3>

=======================================================

According to Newton's Second Law, we know that

F = m*a

where F is the force applied, m is the mass and 'a' is the acceleration.

We see that this is a direct variation equation for F and a, such that m is the constant of variation. It's similar to how y = kx is also a direct variation equation.

Plug in F = 35 and a = 5 to find m

F = ma

35 = m*5

35/5 = m

7 = m

m = 7

The object has a mass of 7 kg

Our equation F = ma updates to F = 7a

Now plug in the force F = 21 to find 'a'

F = 7a

21 = 7a

21/7 = a

3 = a

a = 3

The acceleration will be 3 m/s^2

Notice how a smaller force applied means that the acceleration has also gone down as well.
