If matrix A is a 3x4 and matrix B is a 5x3, what are the dimensions of BA?​

Answer:

y = -x - 4

Step-by-step explanation:

y = mx + b

Slope (m) = -1 (left 1, up 1)

Y-intercept (b) = -4

Given:

Height of access ramp = 6 foot

Ramp ends at a point 40 feet away along the ground.

To find:

The angle of depression in nearest tenth of a degree.

Solution:

Using the given information, draw a figure as shown below.

In a right angle triangle,

[tex]\tan \theta = \dfrac{\text{Perpendicular}}{\text{Base}}[/tex]

In triangle ABC,

[tex]\tan \theta=\dfrac{AB}{BC}[/tex]

[tex]\tan \theta=\dfrac{6}{40}[/tex]

[tex]\tan \theta=0.15[/tex]

Taking tan inverse on both sides.

[tex]\theta=\tan^{-1}(0.15)[/tex]

[tex]\theta=8.5307656[/tex]

[tex]\theta \approx 8.5[/tex]

Therefore, the angle of depression is 8.5 degrees.

Easy math

Answer:

6+

Step-by-step explanation:

very easy math

Answer:

x= 67 degrees and z= 54 degrees

Step-by-step explanation:

Using alternative interior angle, you can see that x is equal to 67 degrees

-In a triangle, there is 180 degrees. Since there are 59 degrees and 67 degrees in the triangle, you will just need to solve for z.

-In order to solve for z, you subtract 180-59-67= 54

The weight of basic kit is 73.33 g and weight of Designer kit 146.68 g.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

let the weight of basic kit be x and weight of designer kit be y.

The weight of 2 basic kites and 2 designer kites are 400g.

and, the weight of 4 basic kites and 1 designer kites are 440g.

So, the system of equation is

2x + 2y = 400.............(1)

4x + y = 440

y = 440 - 4x.............(2)

Solving equation (1) and (2), we get

2x + 2(440 - 4x) = 400

2x + 880 - 8x = 400

-6x = -440

x = 73.33

and, y= 440 - 4(73.33)

y = 146.68

Answer:

First Number is 13

Second Number is 27

Step-by-step explanation:

let x = first number

let 2x + 1 = second number

x + (2x + 1) = 40

3x + 1 = 40

Answer:

5 apples

Step-by-step explanation:

First, we must find the cost of one apple

12/20 = the cost of one apple

= $0.60

Then, we divide 3 by the price of one apple

3/0.6 = amount of apple we can buy

= 5

Answer:

18.5

Step-by-step explanation:

It says

IJ is the midsegment of the triangle. So it divides both adjacent sides in half/at modpoint.

so HF is 10 cm .. half of that is 5 cm

GH is 13 cm.. Half of that is 6.5 cm

now we have IJ = 7 cm given

add all those.. you get 18.5 cm

Answer:

18.5

Step-by-step explanation:

35.

Segment IJ is a midsegment of triangle FGH, so

2HI = 2FI = FH

2HJ = 2JG = GH

FG = 2IJ

Perimeter of triangle IJH = IJ + JH + HI

IJ + JH + HI = 7 + 6.5 + 5 = 18.5

Answer:

14 miles

Step-by-step explanation:

He can row 3.5 miles in .25 hours.

If there are 60 mins in an hour. Take the .25 hour and times by 4 to get a whole hour.

Since 3.5 miles is for .25 hr, take the 3.5 times by 4 to get what he rows in a whole hour.

3.5*4= 14 miles.

Answer:

42 cups of flour

Step-by-step explanation:

12 is 4 times more than 3 (3 × 4 = 12), so we know that we need 4 times 10 1/2 (equal to 10.5) cups of flour.

All we need to do for this is do 10.5 × 4 = x and solve for x.

10.5 × 4 = 42 cups of flour

Answer:

0.33696

Step-by-step explanation:

Given that:

Probability of showing up head (p) = 0.6

Number of flips = number of trials = 5

Probability of getting more than 3 heads

P(x = x) = nCx * p^x * (1 - p)^(n-x)

P(x> 3) = p(4) + p(5)

P(x = 4) = 5C4 * 0.6^4 * 0.4^1 = 0.2592

P(x = 5) = 5C5 * 0.6^5 * 0.4^0 = 0.07776

Hence,

0.2592 + 0.07776

= 0.33696

Following are the calculation to the probability:  

The probability to see the head [tex](p)= 60\%= 0.60[/tex]

Amount of flips = amount of tries = 5

Chances of getting and over three heads:

            [tex]\to P(x = x) = ^n C_x \times p^x \times (1 - p)^{(n-x)}\\\\\to P(x> 3) = p(4) + p(5)\\\\\to P(x = 4) = ^5 C_4 \times 0.6^4 \times 0.4^1 = 0.2592\\\\\to P(x = 5) = ^5 C_5 \times 0.6^5 \times 0.4^0 = 0.07776\\[/tex]

Hence,

                       [tex]\to 0.2592 + 0.07776= 0.33696 \approx 0.34\\\\[/tex]

Therefore, the final answer is "0.34"
