Answer:

13.86 to the nearest tenth.

Step-by-step explanation:

A right angled triangle has three sides and it also has three angles. One of the angles is always 90 degrees while the other two angles are complimentary angles. This means that they add up to give 90 degrees.

The longest side is called the hypotenuse.

One of the shorter side is called the opposite.

The other shorter side is called the adjacent.

From the information given,

The length of the hypotenuse = 19cm

The length of the opposite side = 13cm

The length of the adjacent side = xcm

Applying Pythagoras theorem,

Hypothenuse ^2 = adjacent^2 + opposite ^2

19^2 = x^2 + 13^2

x^2 = 361 - 169 = 192

x = √192 = 13.8564

= 13.86 to the nearest tenth.

A survey 3,000 who bought a new car showed that 900 had problems. What is the relative frequency of the people that had problems
Anit [1.1K]

Answer:

30%

Step-by-step explanation:

Presuming that "survey 3,000" is the total and "900" is the factor who had problems then dividing the total amount by the amount of problems like equal the relative frequency of people that had problems

Math:

Amount of people you had problems / Amount of people who bought the new car.

900 / 3000 = 0.3

Now you need to multiply by 100% (because % in this case is a unit/measurement)

0.3 * 100% = 30%

Julia is taking a test with multiple choice and true/false question the test has twentg question altogether . julia gets five po
Sonbull [250]
X=number of corect
y=number of incorrect
5 points for each correct so 5x
-1 point for each incorrect so -y

5x-y=76
solve for x and y

I like putting it into slope intercep tofrm which is y=mx+b
add y to both sides
5x=76+y
subtract 76 from both sides
5x-75=y
y=5x-76

subsitute values for x and get values for y
remember, that julia cannot answer a negative number of incorrect questions so y must be greater than or equal to 0

so solve for minimum
0<u><</u>5x-76
add 76 to both sides
76<u><</u>5x
divide by 5
15.2<u><</u>x
you cannot answer a fraction of a correct quesiton so round up
16 is the minumum number of queswtions correctlyh answered


so
x<u>></u>16

subsitute 16 for x
y=5(16)-76
y=80-76
y=4

as we subsitute more numbers over 16, we get these points
so (x,y)

How to find the area of each of the shaded sectors and round to the nearest hundredth
Mazyrski [523]

Answer:

1-6 you need to write the JHI DEF where the radius center point is in the middle of each shape next to 1-6 some have 2 shapes so use 6 letters there.

Step-by-step explanation:

1. Area = 72 of 360 = 20% of 716.3 =  143.26inch*2 =JHI

2.Area =  19 of 360 = 68.4% of 69.4  = 47.46km^2 =DEF

3. Area = 92 of 360 = 25.56% of 153.9 = 39.33cm^2

4. Area = 226 of 360 = 64.57% of 706.9 = 456.45ft^2

5.  Area = 74 of 360 =  20.55% of 153.9 =31.63 inch^2

6. Area = 326 of 360 = 90.56% of 1452 -137.07 = 1314.93m^2
