Answer:

Sipho catches up Jabu at 6:30 pm

Step-by-step explanation:

Jabu left town A to travel to town B at 6:00 a.m. he drove at an average speed of 80km/h.

At 8:30 am, when Sipho leaves, we will have traveled 2.5 hours at 80 km/h, so he will be 80*2.5 = 200 km ahead.

From then, his position will be given by:

[tex]J(t) = 200 + 80t[/tex]

Sipho left town A to travel to town B. He drove at an average speed of 100 km/h.

His position will be given by:

[tex]S(t) = 100t[/tex]

At what time will Sipho catch up jabu?​

He will catch up in t hours, and t is found when:

[tex]S(t) = J(t)[/tex]

So

[tex]100t = 200 + 80t[/tex]

[tex]20t = 200[/tex]

[tex]t = \frac{200}{20} = 10[/tex]

He will catch up 10 hours after 8:30 am, that is, 6:30 pm.

Sipho catches up Jabu at 6:30 pm

Answer:

Step-by-step explanation:

Divide each number in the ratio by their greatest common divisor.

  4500 : 80000 = (4500/500) : (80000/500) = 9 : 160

  8100 : 144000 = (8100/900) : (144000/900) = 9 : 160

Answer:

XY is a tangent

Step-by-step explanation:

Given

[tex]XY = 12[/tex]

[tex]WY = 20[/tex]

[tex]WZ = 8[/tex]

Required

Is XY a tangent?

XY is a tangent if:

[tex]WY^2 = XY^2 + WX^2[/tex]

Because XY should make a right angle at point X with the circle

Where

[tex]WX = 2 * WZ[/tex]

So, we have:

[tex]WY^2 = XY^2 + WX^2[/tex]

[tex]WY^2 = XY^2 + (2*WZ)^2[/tex]

[tex]WY^2 = XY^2 + (2WZ)^2[/tex]

[tex]WY^2 = XY^2 + 4WZ^2[/tex]

This gives:

[tex]20^2 = 12^2 + 4*8^2[/tex]

[tex]400 = 144 + 256[/tex]

[tex]400 = 400[/tex]

Yes, XY is a tangent

Answer:

n + 3

Step-by-step explanation:

We need to write the expression equivalent to 1/2 ( 2n + 6) . For that open the brackets and simplify the expression. So that ,

=> 1/2 ( 2n + 6)

=> 1/2 × 2n + 1/2 × 6

=> n + 3

Answer:

The answer should be b. (0,2) because that the order pair for y

Answer:

(2,3) makes the equation false.

Step-by-step explanation:

a. -1 = 1/2(0)-1

-1 = -1

b. 0 = 1/2(2) - 1

0 = 1 - 1

0 = 0

c. 2 = 1/2 (3)-1

2 = 3/2 - 1

2 = .5

d. 1=1/2(4)-1

1=2-1

1=1

Answer:

0.0177 = 1.77% probability that the first defect is caused by the seventh component tested.

The expected number of components tested before a defective component is found is 50, with a variance of 0.0208.

Step-by-step explanation:

Assume that the probability of a defective computer component is 0.02. Components are randomly selected. Find the probability that the first defect is caused by the seventh component tested.

First six not defective, each with 0.98 probability.

7th defective, with 0.02 probability. So

[tex]p = (0.98)^6*0.02 = 0.0177[/tex]

0.0177 = 1.77% probability that the first defect is caused by the seventh component tested.

Find the expected number and variance of the number of components tested before a defective component is found.

Inverse binomial distribution, with [tex]p = 0.02[/tex]

Expected number before 1 defective(n = 1). So

[tex]E = \frac{n}{p} = \frac{1}{0.02} = 50[/tex]

Variance is:

[tex]V = \frac{np}{(1-p)^2} = \frac{0.02}{(1-0.02)^2} = 0.0208[/tex]

The expected number of components tested before a defective component is found is 50, with a variance of 0.0208.

Answer:

[tex]g.h(-3) = \frac{14}{5}[/tex]

Step-by-step explanation:

We are given these following functions:

[tex]g(x) = \frac{x + 1}{x - 2}[/tex]

[tex]h(x) = 4 - x[/tex]

Multiplication function:

[tex]g.h(x) = \frac{x + 1}{x - 2} \times (4 - x) = \frac{(x+1)(4-x)}{x - 2}[/tex]

At x = -3

[tex]g.h(-3) = \frac{(-3+1)(4-(-3))}{-3 - 2} = \frac{(-2)(7)}{-5} = \frac{-14}{-5} = \frac{14}{5}[/tex]

So

[tex]g.h(-3) = \frac{14}{5}[/tex]

Answer:

150

Step-by-step explanation:

Remark

The exterior angle = the sum of the two given interior angles. The first job is to solve for x and then use that to find the exterior angle.

Equation

83 + 6x + 7 = 15x              

Solution

Combine like terms

90 + 6x = 15x        Subtract 6x from both sides.

        6x     6x

90 = 9x                 Divide both sides by 9

90/9 = 9x/9

x = 10

Now the exterior angle = 15x

Exterior angle = 15*10

Exterior angle = 150

Answer:

1. a.$1.09, b. $2.18, c. $3.27, d. $4.36

Step-by-step explanation:

They tell you the price for 1 of something. When they ask for 2 of that same thing, you multiply that price x 2. When they ask for 3 of that same thing, you multiply that price (for 1) x 3. Same if they are asking for 7 or 11, you multiply that number times the price for one.

Does that make sense?

Your answer should be C.

Step-by-step explanation:

Answer:

498/1500

Step-by-step explanation:

tell me if im right please

let h=-12, k=-11 then

(x-h)^2 + (y-k)^2= r^2

(x+12)^2 + (y+11)^2 = 7^2

x^2 + 24x + 144 + y^2 + 22y + 121 = 49

x^2 + y^2 + 24x + 22y + 144+121-49= 0

x^2 + y^2 + 24x + 22y + 216 = 0 is the required eq

Answer:

[tex] \displaystyle 5\sqrt{2}[/tex]

Step-by-step explanation:

we have a right angle isosceles triangle

in order to figure out the length of each leg we can consider Pythagoras theorem given by

[tex] \displaystyle {a}^{2} + {b}^{2} = {c}^{2} [/tex]

remember that,

isosceles triangle has two equal legs so a=b and given that the the hypotenuse is 10

substitute:

[tex] \displaystyle {a}^{2} + {a}^{2} = {10}^{2} [/tex]

simplify addition:

[tex] \displaystyle {2a}^{2}= 100[/tex]

simplify square:

divide both sides by 2:

[tex] \displaystyle {a}^{2}= 50[/tex]

square root both sides:

[tex] \displaystyle {a}^{}= \sqrt{50}[/tex]

[tex] \displaystyle {a}^{}= 5\sqrt{2}[/tex]

hence,

the length of each leg is 5√2

Step-by-step explanation:

Answer:

Subject : Tomato plant

Explanatory variables : Watering condition ; Fertilizer addition

Treatment : daily watering ; half fertilizer ; full fertilizer

Response variable = Number of tomato picked

Step-by-step explanation:

Subjects are the individuals, animals or plants upon which treatment is applied. The subject here are the tomato plants

The Explanatory variables are the independent variables upon which we want base the variation of the dependent variable. The Independent variables are the watering condition a d the amount of fertilizer added.

Treatment : These are the actual changes made or applied on the subject, they include, daily watering, full or half fertilizer application.

Response variable : The number of tomatoes picked. This is also called the dependent variable, it is the outcome which may be due to the effect of the independent variable.

Step-by-step explanation:

velocity = distance/time taken

distance=velocity ×time taken

distance=80×4

distance=320kilometers
