85 x 0.07 = 5.95

Total = 85 + 5.95 = 90.95%

Answer:

90.95%  

Step-by-step explanation:

It has been given that our current quality score is 85%. We are asked to find our new quality score after an increase of of 7%.

\text{New score}=\text{Old score + Increase in old score}

\text{New score}=85+7\%\text{ of }85  

\text{New score}=85+(\frac{7}{100}\times 85)

\text{New score}=85+(0.07\times 85)

\text{New score}=85+5.95

\text{New score}=90.95  

Therefore, the new score will be 90.95%.

Hitung jarak di antara titik P(7, 1) dengan titik Q(7, 8) ​
MaRussiya [10]

Answer:

7 units

Step-by-step explanation:

Distance between 2 points

=\sqrt{(y1 - y2)^{2}  + (x1 - x2) {}^{2} }

Thus, distance PQ

=\sqrt{(8 - 1)^{2}  + (7 - 7)^{2} }  \\ = \sqrt{7^{2} }  \\  = 7

Or you could simply take 8-1= 7 since both points have the same x-coordinate. Thus, PQ is a vertical line and the distance between them is due to the difference in their y-coordinate.

Write a sine function that has an amplitude of 5, a midline of 3 and a period of 1/8.
vodomira [7]

Answer:

y=5sin(16pix)+3

Step-by-step explanation:

Amp=5 means our curve is either y=5sin(bx+c)+d or y=-5sin(bx+c)+d.

y=sin(x) has period 2pi.

So y=sin(bx) has period 2pi/b.

We want 2pi/b=1/8.

Cross multiplying gives: 16pi=b

y=5sin(16pix+c)+d

d=3 since we want midline y=3.

y=5sin(16pix+c)+3

We can choose c=0 since we aren't required to have a certain phase shift.

y=5sin(16pix)+3

Write an expression in simplest form for the perimeter of each figure.
Vlad [161]

Answer: P=5y+11x


Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

- By definition, the perimeter of the figure is the sum of the lenght of each side. Then, you must make the addition as following:

P=2.8y+2x+2.2y+5x+4x

Where P is the perimeter of the figure.

- Add the like terms, then, you obtain the following expression in simplest form:

P=5y+11x
