A car travels a distance of 130 miles in a time of 1.8 hours. What is its average speed rounded to 1dp?

Answer:

X = [tex]\sqrt{21}[/tex] or 4.5825756...

Step-by-step explanation:

[tex]A^{2} + B^{2} = C^{2}[/tex]

[tex]10^{2} + x^{2} = 11^{2}[/tex]

[tex]x^{2} = 11^{2} - 10^{2}[/tex]

[tex]x^{2} =121-100[/tex]

[tex]x^{2} =21[/tex]

x = [tex]\sqrt{21}[/tex]

Hope this helps!

Answer:

x=[tex]\sqrt{220}[/tex]

Step-by-step explanation:

Since this is a right angle triangle, and we have two lengths already found, we can use pythagoras to find x.

We know that  

a²+b²=c²

Where a, and b are the smaller lengths (the adjacent and opposite), and C is always the longest one (the hypotenuse).

In this case,

x=a

b=6

c=16

So to plug these into the equation, we get:

x²+6²=16²

To isolate x,

we get:

x²=16²-6²

x=[tex]\sqrt{16^2-6^2}[/tex]

[tex]x=\sqrt[]{220}[/tex]

_________

[tex] \: [/tex]

x² = 16² - 6²

x² = 256 - 36

x² = 220

x = √220

x ≈ 14.9cm

Answer: 30

Step-by-step explanation: square 24 and 18 (576 & 324) then add them together (900), then the square root of 900 is 30, so 30.

Answer:

Step-by-step explanation:

To find the diagonal path way, use Pythagorean theorem.

Diagonal² = length² + width²

                 = 24² + 18²

                 = 576 + 324

                = 900

diagonal = √900 = √30 *30

diagonal = 30 ft

Answer:

x = 9

Step-by-step explanation:

( 17x + 7 )° = ( 13x + 3 )° + 40°

17x + 7 = 13x + 3 + 40

17x - 13x = 43 - 7

4x = 36

x = 9

Answer: 1/4

Given : On average, Carson spends about 26% of his allowance each month on candy and soft drinks.  

To Find : When creating a circle graph of what Carson does with his money, which of the following fractions would be the best to represent how much he spends on food?

If these are your Choices:

A) 1/4

B) 1/3

C) 3/4

D) 1/2

Solution:

To Convert fraction into % multiply by 100  

(1/4) * 100 = 25 %

(1/3) * 100  = 33.33 %

(3/4) * 100 = 75 %

(1/2) * 100 = 50 %

Therefore 1/4 fraction best represent how much he spends on food

Answer:

Step-by-step explanation:

Option A, is true about 73

As it is a prime number because it has only two distinct divisors: 1 and itself (73)

I'm pretty sure it's B because 737 isn't a prime number but 73 is a prime number

Answer:

So because the range is between 20 and 40, it can be noticed through counting.

5, 10, 15, 20, 25, 30, 35, 40

3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39

The number of balls in the box, just from the information by 5, is either ending in 1 (for example 21, 31) or 6 (26, 36)

From counting by 3 with that information, it would mean the number is most likely 26 balls, since there would be one left when Max reaches 25 counting by 5, and two left when he reaches 24 counting by 3.

Answer:

6 × 4 = 25

6 + 4 = 10

Answer:

Step-by-step explanation:

x * y=-21

x+y =-10

we use elimination method to solve

x * y = -21

x + y = -10

x = -11

then replace the y s with -11

x * y = -21

x * -11 =-21

x *-11 + -11 = -21+-11

x = -32

x + y = -10

x +-11 = -10

x + -11--11 = -10--11

x + 0 = -10+11

x = 1

x =1

y = -11

7

Step-by-step explanation:

35/5=7

Hope this helps!

Answer: We know that there is 35 games per season and is played throughout 5 months. If in each month the same number of games were played we would have to do 35/5 which is equal to 7. To check your work you can do 5 times 7 which is 35. Remeber opposite of division is multiplication and opposite of multiplication is division. SO, your answer is 7 football games per month.

Step-by-step explanation:

13).

This is an equilateral triangle.

We see that all 3 angles are equal,  so all sides are equal also.

So 2x - 6 = 10

2x = 16

x = 8.

Answer:

Step-by-step explanation:

If I am correct the triangle has equal sides and I think you're trying to find x. So 10=2x-6 and then solve. Once you get the x (assuming you know how to get it) plug it into the equation (of 2x-6) and get the remaining number. (For example: if x=2 then 2x2-6, then you solve: 2x2=4 4-6=-2) I don't know if you want the answer though...

(depends if you want x or the rest)

[tex] \frac{0.2x - 3.2}{5} = 1.8 \\ 0.2x - 3.2 = 1.8 \times 5 \\ 0.2x - 3.2 = 9 \\ 0.2x = 9 + 3.2 \\ 0.2x = 12.2 \\ x = \frac{12.2}{0.2} \\ \boxed{ x = 61}[/tex]

Step-by-step explanation:

5/9×3/10= 15/90 simplification is 1/6

the correct is 1/6

Answer:

The 4th answer is correct

Step-by-step explanation:

[tex]\frac{5}{9} *\frac{3}{10} \\\\[/tex]

[tex]\frac{5*3}{9*10}[/tex]

[tex]\frac{15}{90}[/tex]

Now you can make the answer as the simplest form divide both sides by 15

[tex]\frac{15}{90} =\frac{1}{6}[/tex]

ANSWER IS,

[tex]\frac{1}{6}[/tex]

Hope this helps you.
