What is the area of the triangle when a=14 and c=50 what is b?

Answers

Answer 1

Answer:
No answer is possible.
Without the picture ... or a detailed explanation ...
it's not possible to tell what 'b' is.

Answer 2

Answer: B is 116. The area of any triangle should equal 180. So you add 14 plus 50 to get 64 and then you subtract 180 minus 64 and get 116. Got it?

Answers

Argh! My answer was erased!

We need to cut a 15m rope into 20 equal pieces. Written mathematically, it is as follows:
15/20 = length of rope segment in meters (a)
15/20 = a

Simplify
3/4 = a

In meters, each rope segment is 3/4m long. But, we don't want meters. We want centimeters.

100 cm = 1 m

3/4(100) = length of rope segment in centimeters (x)
3/4(100) = x

300/4 = x
75 = x

Each segment of rope is 75 cm long.

The rope needs to be cut into 20 pieces, so 15/20, this will give you 3/4 of a meter per piece. Multiply 100 (100 cm in a meter), .75*100= 75 centimeters in a piece...

A scientist is interested in the effect of time spent with parents and number of hoursyouth spend watching television. The researcher knows that the average teen whose
parents work outside the home spends 20 hours a week watching television. The
population mean = 20 and the standard deviation of the distribution is equal to 5.
Calculate the z-scores for the following individual times:________
If X = 5, z= ________
If X = 37, z= ________

Answers

Answer: If X = 5, z=-3

If X = 37, z= 3.4

Step-by-step explanation:

We know that the formula to find the z-score for any random variable x is given by :-

$z=(x-\mu)/(\sigma)$

, where $\mu$ = Population mean

$\sigma$ = Population standard deviation.

As per given , we have

$\mu=20\n\n\sigma=5$

Then , the z-score for x =5

$z=(5-20)/(5)=(-15)/(5)=-3$

i.e. If X = 5, z=-3

When x =37,then $z=(37-20)/(5)=(17)/(5)=3.4$

i.e. If X = 37, z= 3.4

Jenny is on the local swim team for the summer and has swim practice four days per week. The schedule is the same each day. The team swims in the morning and then again for 2 hours in the evening. If she swims 20 hours per week, how long does she swim each morning?

Answers

Answer:

Number of hours Jenny swims each morning = 3 hours

Step-by-step explanation:

Let Jenny swims 'x' hours in the morning each day.

She swims 2 hours in the evening too.

Total hours she swims each day = (x + 2) hours

If her team swims 4 hours per week then number of hours she swims = 4(x + 2)

If she swims 20 hours in a week then,

4(x + 2) = 20

(x + 2) = 5

x = 5 - 2

x = 3 hours

Therefore, Jenny swims 3 hours each morning.

How many solutions does this system have?Y = x + 5
Y = -5x – 1
A) One
B) None
C) Infinite
D) Two

Answers

Well this does take some work on scratch paper but ill let you know that we have to plug these in to make one whole big equation
lets do that!
x + 5 = -5x - 1 now add +1 to both sides of the equation
+ 1 = +1 it cancels out on the right side and we solve on the left
*****************
x + 6 = -5x Now lets subtract that(1x) from both sides
-1x = -1x ( if x stands alone, theres always an imaginary 1 right by it)
************** now -5 - 1 = -6 so its -6x
6 = -6x Now divide both sides by -6 to isolate x to be alone
÷-6 = ÷6 It cancels out on the right side and we solve on the left
************ 6 ÷ -6 = 0 so lets see what we have
0 = x
Since zero is still a number this means there is only 1 solution!
Answer = A.) one
I hope this helps!

Factorise x² + 4x + 3.I understand everything perfectly until I have to split the two sections, add up and pull out the common factors: x² + 3x: common factor is x 1x + 3: common factor is 1 From here I do not understand how you get to the answer which I do know is (x + 1) • (x + 3). None of the explanations out there give detail to this step. I don’t understand how adding those two groups up (while pulling out common factors) will give you (x + 1) • (x + 3)! I would hugely appreciate any help on this! Thank you :)
