Mary covered her kitchen floor with 10 tiles. The floor measures 6 feet long by 5 feet wide. The tiles are each 3 feet long and
Talja [164]

Answer:

1 feet wide

Step-by-step explanation:

We first need to find the area of the floor.

6*5=30

Then we divide the area by the number of kitchen tiles to get the area of each tile.

30/10=3

After this, we set up a L x W = A equation to solve for w.

3*w=3

3w=3

w=1

Ashad is rewriting the expression 28 a + 36 a b as a product. Which statements about the expression are accurate and relevant to
Gala2k [10]

Answer:

(B)The GCF of the numbers(28 and 36) in each term in the expression is 4.

(C)The GCF of the variables(a and ab) in each term in the expression is a.

(E)The factored form of the expression is 4a(7+9b)

Step-by-step explanation:

Given the expression: 28a+36ab

If we write it as a product, we obtain:

28a+36ab=4a(7+9b)

We can see the following

  • The GCF of the numbers(28 and 36) in each term in the expression is 4.
  • The GCF of the variables(a and ab) in each term in the expression is a.
  • The factored form of the expression is 4a(7+9b)

The correct options are B, C, and E.

1. A weight suspended from a spring is set into oscillating motion by compressing it to a
Naya [18.7K]

Question:

Complete question for this is to find the equation for this and may be the graph.

Explanation:

As for the oscillation motion, initially peak is occurring hence it will be a cosine function with peak value of 3(cm).

To calculate time period, the whole cycle should be 360°

i.e.

cos (Xπ.t) = cos (360)

as the cycle completes at 1.2 sec hence by putting t=1.2, answer should be 360.

i.e.

X*180*t=360

X*180*1.2=360

X=5/3

So, the required equation is

f(x)=3.cos(5\frac{\pi }{2}.t)

Graph for this equation is attached here with this answer.

In graph,

x-axis: t=0 ~ t=1.2

y-axis: f(x)=-4 ~ f(x)=4
