Angel saved $100 a week for a year. She spent 40%
of her savings on a new bed. How much did she
spend on the bed?

Answer:

36

Step-by-step explanation:

Answer:

x = 9 degrees

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp side/ hypotenuse

sin x = 15/91

Taking the inverse sin of each side

sin ^-1 (sin (x)) = sin ^ -1( 15/91)

x =9.487658996

To the nearest degree

x = 9 degrees

Answer:

A correlation coefficient shows where one variable changes in results to the other. A line of best fit is the best fit line that passes through or near the graphed data. It is used to describe data and predict where new data will appear on the graph. These two methods help to find correlation between variables as they are used to predict how and where variable are and will go in correlation to one another.

Th matrix is missing. The matrix is :

[tex]\begin{bmatrix}1 &-4 &4 \\ -4 &16 & 4 \end{bmatrix}[/tex]

Solution :

The column of the matrix are [tex]\begin{bmatrix}1\\ -4\end{bmatrix}[/tex] , [tex]\begin{bmatrix}-4\\ 16\end{bmatrix}[/tex], [tex]\begin{bmatrix}4\\ 4\end{bmatrix}[/tex]

Now each of them are vectors in [tex]$IR^2$[/tex]. But  [tex]$IR^2$[/tex] has dimensions of 2. But there are 3 column vectors, hence they are linearly dependent.

Therefore, the column of the given matrix does not form the [tex]\text{linearly independent set}[/tex] as the set contains [tex]\text{more vectors}[/tex] than there are entries in each vector.

Therefore, option (D) is correct.

34.5575191895

so circumference for semi circle is 34.56

times that by two u get circumference for circle

which is 69.12

formula for circle =

C=D*pi

so D=C/pi

so D=69.12/pi

approximately = 22

and divide that by 2 to find radius

22/2 =11

Answer:

The answer is "[tex]8\times 9=70+2[/tex]"

Explanation:

The distributive property indicates that by simply multiplying integers (factors) together, each factor would be split into 2 accompanying texts, both added by the other and that both products would be added together. Its distributive property explains that How we break down one of the components doesn't matter.

[tex]\to 8\times 9=70+2\\\\\to 72=72[/tex]

So, L.H.S=R.H.S

Answer: option A and D results in 3 significant figures.

Step-by-step explanation:

A. [tex]101 - 83.4 =17.6[/tex]

The number 17.6 has three significant figures.

B. [tex]121 - 1.75 =119.25[/tex]

The number 119.25 has 5 significant figures

C. [tex]7.23 + 12.6=19.83[/tex]

The number of 19.83 has 4 significant figures.

D. [tex]17\cdot 1.5=25.5[/tex]

The number of 25.5 has 3 significant figures.

Hence, option A and D results in 3 significant figures.

Answer:

The speed of the train is 40 km/h.

Step-by-step explanation:

Since a train travels a distance of 120 km at a constant speed of V km / h, and if the speed is reduced by 10km / h, then the time taken to the journey is increased by one hour, to find the constant speed V of the train, the following calculations must be performed:

20 x 6 = 120

10 x 7 = 140

30 x 4 = 120

20 x 5 = 100

40 x 3 = 120

30 x 4 = 120

Therefore, the speed of the train is 40 km/h.

Answer:

3 and -2

Step-by-step explanation:

xy = -6

x + y = 1

let 'x' = y-1

y(y-1) = -6

y² - y + 6 = 0

(y-3)(y+2) = 0

y = 3 and -2

Step-by-step explanation:

Answer:

Red light flashes once every 6 seconds, blue light flashes once every 10 seconds, so the next time the blue light flashes(20 seconds), the red light would have completed 18 seconds and the next time blue light flashes (30 seconds), the red light would also be flashed at the same time.

Step-by-step explanation:

Answer:

k = 18

when x = 4, y = 3, z = -24

Step-by-step explanation:

x = k * y * z

Find k when x = 4, y = 3, and z = 24

4 = k * 3 * 24

4 = k * 72

4 = 72k

k = 72/4

k = 18

find z when x = -3 and y = 4

x = k * y * z

-3 = 18 * 4 * z

-3 = 72 * z

-3 = 72z

z = 72/-3

z = -24
