Paraphin [41]

Answer:amount of decrease 290 ;numbers of chairs 5510

Step-by-step explanation:

Stablish the proportion 5800/100%=x/5% then solve for x. ; x=(5%/100%)*5800 = 290 which is the decrease. Then make the difference 5800-290 and you get 5510

Can angles also use the reflexive property?

DochEvi [55]

Here is an example of showing two angles are congruent using the reflexive property of congruence: Separating the two triangles, you can see Angle Z is the same angle for each triangle. Since they are the same angle, the angle is congruent to itself.

Loc can mow his entire lawn in 20 minutes; Loc's roommate Reza needs 30 minutes to mow the entire lawn. If Loc starts mowing at

ycow [4]

Loc and Reza together will finish the entire mowing process on the lawn at 1:14 p.m.

<h2>Calculation of total mowing time taken</h2>

Loc mow the total area in 20 mins.

So, his pace is 1 lawn / 20 minutes or 1/20th of a lawn each minute.

Reza's pace is 1 lawn / 30 minutes, or 1/30th of a lawn each minute because he can mow the grass in that amount of time.

Reza joins Loc after he has been mowing for 5 minutes. He can mow 1/20th of the grass in these 5 minutes, which is 5/20th of the lawn =1/4th lawn

There is currently just

1-1/4=3/4 of the lawn left to complete.

We may construct the following equation by assuming that they mow together for x mins:

1/20x + 1/30x = 3/4 [amount done by Loc + Reza = total amount]

⇒(3x+2x)/60x = 3/4

⇒5x/60 = 3/4

⇒x/12= 3/4

⇒4x=36

⇒x= 9 mins

So, when they collaborate, they can complete the lawn in 9 minutes.

Hence, Loc mows alone for 9+5 mins = 14 mins

Therefore, it is concluded that starting at 1 p.m they finish the mowing at 1:14 p.m.

Write 4x2 + 16x - 9 in vertex form.

Alexxx [7]

We know that the vertex form of any quadratic function is the form:

$f (x) = a(x - h)^2 + k$

The given quadratic function is $f(x) = 4x^2 + 16x - 9$

To convert it into the vertex form we will have to complete the square of the quadratic expression given here which may be done as shown below:

$f(x) = 4x^2 + 16x - 9 =4(x^2+4x)-9$

Thus, $f(x)=4(x^2+4x+\mathbf{4})-\boldsymbol{\mathbf{16}}-9$ (This is because adding a 4 inside the parentheses to complete the square is equivalent to adding 16 to the whole expression and thus we need to subtract 16 from the overall expression.)

$\therefore f(x)=4(x+2)^2-25$

The above is the vertex form of the original given function, $f(x) = 4x^2 + 16x - 9$ .

Data was collected for a sample of organic snacks. The amount of sugar (in mg) in each snack is summarized in the histogram belo

yanalaym [24]

Answer:

The sample size is 30.

Step-by-step explanation:

The sample size of a histogram can be calculated by summing up all the frequencies of all the occurrences in the data set

From the question the frequency is given as

Frequency = 2 4 6 8 10

The sample size n =

2 + 4 + 6 + 8 + 10

= 30

Therefore the sample size n of the data set = 30
