PLEASE HELP 5 of 5
A, B & C form a triangle where Z BAC = 90°,
AB = 2.6 mm and CA = 14.2 mm
Find the length of BC, giving your answer rounded to 1 DP.
BC =
mm
PLEASE HELP

Answer:

C and A

Step-by-step explanation:

So first, off, to find the length of a line, we can use pythagreons theorm.(A^2+B^2=C^2) The cahnge in x squared and the change in y squared will give us C, which is the line length. You can count the tiles like this:

From the bottom point, lets count up the x coordinates till we hit the x coordinates of the top point. I got 3.

Next is the y coordinates.

When I count up until I reach the top point, I get 7. Lets plug these numbers in:

3^2+7^2=C^2

Use the square root on eahc number except for the unknown(C)

=

9+49=c^2

Add the two numbers together:

=

58=c^2

Take square root:

7.61=c^2

This can just be rounded to 7.6

This looks like C

So that is your first answer.

Next we have a table.

We need to look at the section of people that have both brown hair and eyes.

When I look at the table, I see 30 people whom how both these charcteristics.

When you looka the total people in the bottom right corner, you see that there are 120 people.

We do not even need to calculate percentage.

30 is 1/4 of 120.

What is 1/4 of 100%

25%

So the people with both brown eye/hair color is 25%

THis looks like answer A

I hope this helps! :)

Answer:

43.566 ft

Step-by-step explanation:

Straight sides: 2 long 1 short

2 x 10 + 8 = 28 ft

Curved side: Remember that the circumference of a circle is 2πr or πd.

Since this is a semicircle, divide the circumference you get by 2.

From the diagram: d = 8

total circumference = 8 x π = 8π

semicircle = 8π ÷ 2 = 4π ft

Total perimeter

= (28 + 4π) ft

= (28 + 12.566) ft (5sf)

= 43.566 ft (5sf)

The radius of the hemicircle is r = 8/2 cm = 4 cm.

So the perimeter of the hemicircle part is

[tex]\pi \times r \: = (22 \div 7) \times 4 = 12.57 \: cm[/tex]

The perimeter of the rectangular part = 10+10+8 = 28 cm.

So, the final answer is

[tex]28 \: cm + 12.57 \: cm = 40.57 \: cm[/tex]

Answer:

D. infinitely many solutions

Step-by-step explanation:

to find how many solutions the equation have, we can solve it

here's the given equation:

2(2x-3)+6=4x

our goal is to isolate the variable onto one side

do the distributive property shown in the equation (multiply both 2x and -3 by 2)

4x-6+6=4x

combine like terms (add -6 and 6)

4x=4x

subtract 4x from both sides, as we still have the variable on both sides

0=0

0 is always equal to 0; that's an identity

if we get to a point in an equation where we get an identity as the answer (ex. 3=3 or in this case, 0=0), the answer is all real numbers, or infinitely many solutions

Answer:

D. Infinitely many solutions.

Answer:

12

Step-by-step explanation:

mrk me brainliest plzzzzzzzzzz

Answer:

b) 12

Step-by-step explanation:

The first image shows the top 2 numbers as 5 and 2 = 5 * 2

=> 10

The Second image shows the top 2 numbers as 3 and 3 = 3 * 3

=> 9

So, the third image shows the top 2 numbers as 2 and 6 = 2 * 6

=>12

Therefore, the missing space in the third circle is b) 12

Answer:

10:38

Step-by-step explanation:

2 hours back from 1:15

11:15

37 minutes back from 11:15

10:38

The start time is 10:38.

Answer:

10:38 am

Step-by-step explanation:

You can use a number line or clock to find the start time

x = 0:15 min - 0:37 min x = -0:22 min

y = 60 min - 22 min y = 38 min

Time = 12:38

1st, subtract the minutes from the end time. If the value is negative, it means that the time goes back into the previous hour.

Subtract from 60 minutes. Time after going back 37 minutes.

Next, subtract the hours from the time. 11:38 am 10:38 am and 10:38

Next, subtract the hours from the time. Going back 1 hour. Going back 2 hour.

Start time is 10:38

Answer:

13 u²

Step-by-step explanation:

Answer:

A] 1500 + 0.025x , 1250 + 0.055x ; B] Sales value = 8333

C] Offer 1, if prefers more fix salary over additional incentive. And, offer 2 if  prefers additional incentive over fix salary.

Step-by-step explanation:

Let the sales be = x

A] Offer 1 = 1500 + 2.5% comm on sales = 1500 + 2.5%x = 1500 + 0.025x

Offer 2 = 1250 + 5.5% comm on sales = 1250 + 5.5%x = 1250 + 0.055x

B] Value of sales, resulting in total salary : at equation 1 = equation 2

1500 + 0.025x = 1250 + 0.055x

1500 - 1250 = 0.055x - 0.025x → 250 = 0.03x

x = 250 / 0.03 →  x (Sales value) = 8333

C] Which job she should take, would depend on her preferences.

If she wants more fixed salary, & less above per unit achievement, she should take offer 1 as fixed salary 1500 > 1250. If she wants less fixed salary & more additional incentives, she should take offer 2, as commission 5.5% > 2.5%

Given

There are 3 blue and 1 yellow marble

The chance of picking two marble out of 3 is [tex]^3C_2[/tex]

The total no of ways of picking 2 marbles out of 4 is [tex]^4C_2[/tex]

Therefore, the probability of picking 2 blue marbles

Answer:

1/4 ( x + 12 ) = 2 : x = -4

Step-by-step explanation:

4 x 1/4 (x + 12 ) = 2 x 4

x + 12 = 8

x + 12 - 12= 8 - 12

x = -4

Answer:

153.9

Step-by-step explanation:

Answer:

(6, 0 )

Step-by-step explanation:

A translation to the left means subtract 2 from the x- coordinate

A translation down means subtract 4 from the y- coordinate

Then

(8, 4 ) → (8 - 2, 4 - 4 ) → (6, 0 )

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

Explanation:

The notation [tex]a_1[/tex] refers to the first term. So the first term is 21.

The d = -3 is the common difference. It's the value we add onto any given term to get the next following term.

We can say:

second term = (first term) + (common difference)

second term = [tex]a_1 + d[/tex]

second term = 21 + (-3)

second term = 18

Through similar steps, you should find that the third term is 15, the fourth is 12, and so on. Each time we decrease by 3.

The arithmetic sequence would be: 21, 18, 15, 12, 9, ...

The first three terms are 21, 18, and 15.

Answer:

immma send you the link friend me on hereStep-by-step explanation:

Answer:

a= 180-60-55=65

we know that the angle of a flat(?) ground would be 180, so we can take away the 60 and 55 to find a.

b=180-90-65=25

the sum of interior angle of a triangle would be 180, now we know what a is, also the right angle is 90, now we can take away the 90 and 65 to find b.  

c=25

c is 25, because two angles on both sides of a X is the same
