What is 8/9 of 3/8 equal to

1 answer:

7 0

8/24 is the answer

Let’s draw a picture to figure that out.
Let’s make a rectangle and split it into eight pieces since we are finding 8/9 of 3/8. Next, we will circle 3/8 because that is what we are diving up. Then we split the 3/8 into nine pieces since we are diving by 8/9. Then we will have one more group of three to split into nine pieces, so let’s do that. Then, since 9 divided by 3 is 3, we will split the last two pieces into 3 pieces each. Then we will shade in 8/9 of the circled pieces. Count all the pieces now, which should be 24 pieces. Then how many of those are shaded? 8/24 is the answer.

Answer:

Step-by-step explanation:

A. because the line of best fit has to be at best fit between the points so is a good approximation of where all the points are heading when you try to predict something.

In PQR the measure of R=90 the measure of P=62 and RP=8.6 find the length of QR to the nearest tenth of a foot.

alex41 [277]

Answer:

QR = 4.6 ft

Step-by-step explanation:

By applying tangent rule in the given triangle PQR,

tan(62°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

= $\frac{8.6}{QR}$

QR = $\frac{8.6}{\text{tan}(62)}$

QR = 4.573

QR ≈ 4.6 ft

Question 1

cos(C) = adj/hyp
cos(C) = BC/AC
cos(C) = 15/17

Answer: Choice C) 15/17

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

Question 2

sin(E) = opp/hyp
sin(E) = FD/DE
sin(E) = 24/25

So angle E is the answer

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

Question 3

AC is the adjacent side to the given angle A = 33 degrees
AB = 14 is the hypotenuse

cos(angle) = adjacent/hypotenuse
cos(33) = x/14
14*cos(33) = x
x = 14*cos(33)
x = 11.741
x = 11.7

Answer: 11.7

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

Question 4

x = length of board

cos(angle) = adj/hyp
cos(55) = 6/x
x*cos(55) = 6
x = 6/cos(55)
x = 10.46068
x = 10.5

Answer: 10.5

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

Question 5

112 is the adjacent side to the given angle 62 degrees
x = height of building, which is the opposite leg

tan(angle) = opp/adj
tan(62) = x/112
112*tan(62) = x
x = 112*tan(62)
x = 210.641364
x = 210.6

Answer: 210.6

How to convert 1/4 to decimal form. How do I start that ? I obviously know it’s .25 but how do I show work ?

RideAnS [48]

Answer:

(1/4 x 1 ) = 0.25

or (1/4) x 1 = 0.25

Step-by-step explanation:

We are doing the opposite to finding 25%

Which is 1/4 of 100%

We do this an opposite (not as inverse)

To find percentage increase as you can compare below.

or as percentage increase

230 x 0.25 (x 100) = 287.50

Even though we are not finding increase for 1/4 by changing it to decimal form, this practice does use the (x1) element in brackets and does identify the distribution.

Answer:

f(-2) = 4

Step-by-step explanation:

The function has three definitions depending on the value of x.

You are looking for the value of the function at x = -2.

-2 is in the interval x <= -1, which is the first line of the definition of the function.

We use the first line of the definition of the function.

f(x) = -2x for x <= -1

f(-2) = -2(-2) = 4

Answer: f(-2) = 4
