What is the value of x

Mathematics
2 answers:
Maslowich3 years ago

Answer:

x=4.5

Step-by-step explanation:

The triangles are similar (bases are parallel so bottom angles are equal (corresponding), hence they're similar by AA)

Since they're similar, their sides are in ratio:

(x+6)/(x+x+6)=(30-9)/(30)

(x+6)(30)=(2x+6)(21)

30x+180=42x+126

12x=54

x=4.5

Answer:

Assuming the other side is 30, x=12

Step-by-step explanation:

X+(X+6)=30

2x+6=30   (open the brackets by distributing the plus sign inside)

2x=24       (subtract 6 from both sides)

x=12          divide both sides by 12

This makes sense because of x is 6, and x+6 is 18, 6+18=30.

Assignment: generating frequencies for compound events investigation fill out this table to show the sample space for a roll of
m_a_m_a [10]

Total 36 outcomes are possible on rolling two dices simultaneously

A sample space is a collection or a set of possible outcomes of a random experiment. The sample space is represented using the symbol, “S”. The subset of possible outcomes of an experiment is called events. A sample space may contain a number of outcomes that depends on the experiment

A dice has 6 possibilities (1,2,3,4,5,6) , thus two when dices thrown together will have 36 outcomes in it's sample space. It's sample space is shown in picture attached below.

Please help. Find the value of x
Oliga [24]

Answer:

x  =24

Step-by-step explanation:

Call the angle in the lower right corner y

The outside angles add to 180 degrees for the large triangle

41+ 94+ y = 180

135 + y = 180

y = 180-136

y =45

The small triangle in the lower right also has angles that add to 180

y+ 111+x = 180

45+111+x = 180

156 + x = 180

x = 180-156

x =24

Baxter drives a delivery truck.He travels 399 km in 7 hr. At what speed does Baxter drive In kilometers per hour
attashe74 [19]

Answer:

Baxter drives at 57 kilometers per hour.

Step-by-step explanation:

In order to find the answer, you have to use the following formula to calculate the speed:

speed=distance/time

distance=399 km

time=7 hours

Now, you have to replace the values in the formula:

speed=399 km/7 hours

speed=57 km/hour

According to this, the answer is that Baxter drives at 57 kilometers per hour.
