Answer:

75%

Step-by-step explanation:

There are 136 people on a train

34 are children

Therefore the percentage of people that are adults can be calculated as follows

= 136-34

= 102

= 102/136 × 100

= 0.75 × 100

= 75%

Hence 75% are adults

Answer:

The answer is C. 6.07 × 10^-4

Answer:

120.4ft

Step-by-step explanation:

Find the diagram in the attachment.

The triangle shown is a right angled triangle with the side DE as the hypotenuse, EF is adjacent side while DF is the opposite side.

To get DE, we will use the SOH CAH TOA trigonometry identity

Using CAH which is defined as:

Cos(theta) = Adjacent/Hypotenuse

Cos 79°= 23/Hypotenuse

Hypotenuse = 23/cos79°

Hypotenuse = 23/0.191

Hypotenuse = 120.4feet

DE = 120.4feet (to nearest tenth)

Answer:

57.5

Step-by-step explanation:

Recognize our numbers

3,5,34.50

Three uniform shirts sell for 34.50

34.50/3

=11.5

How much will five cost?

5x11.5

=57.5

Hope this helps!

Answer:

55.25

Step-by-step explanation:

1. First we need to work out the price of ONE shirt. To do that we divide the total price of 3 shirts by 3.

34.50 / 3 = 11.05

2. Now we know that the price of one shirt is $11.05p we can multiply that by 5 to get the price of 5 shirts.

11.05 * 5 = 55.25

= $55.25p

Answer:

distributive property

Step-by-step explanation:

have a great day

Answer:

: 5x + 4(3 + 2x)

: 5x + 12 + 8x

: 5x + 8x + 12

: 13x + 12 Distributive Property

Answer: 7/12

Step-by-step explanation:

1/3 + 1/4

1/3 = 4/4 * 1/3 = 4/12

1/4 = 3/3 * 1/4 = 3/12

4/12 + 3/12 = 7/12

Answer:

Length of ladder (hypotenuse) = 13 ft

Step-by-step explanation:

Given:

Length of base (base) = 5 ft

Length of ladder (hypotenuse) = a

Distance between ground and ladder top (perpendicular) = a - 1

Find:

Length of ladder

Computation:

a² = 5² + (a-1)²

a² = 25 + a² - 2a + 1

2a = 26

Length of ladder (hypotenuse) = 13 ft

Answer:

3√41

Step-by-step explanation:

The diagonal can be gotten using the pythagoras theorem

d² = l²+w²

d² = 12²+15²

d² = 144 + 225

d² = 369

d = √9*41

d = 3√41

Hence the diagonal is 3√41

Answer:

Step-by-step explanation:

Substitute values and solve for r the equation of the time difference:

Raul's speed is 17 mph

Answer:

[tex] \huge \boxed{ \boxed{ \red{ \tt17 \: mph}}}[/tex]

Step-by-step explanation:

let's the speed of Raul be x

likewise

Miguel can drive 4 times as fast as Raul can ride his bicycle

therefore

4x

according to the question

[tex] \sf \frac{68}{4x}+3=\frac{68}{x}[/tex]

[tex] \implies \sf \frac{68 + 12x}{4x} = \frac{68}{x} [/tex]

[tex] \sf factor \: out \: 4 \: and \: reduce \: it : \\ \sf \implies \frac{4(17 + 3x)}{4x} = \frac{68}{x} \\ \\ \implies\sf \frac{17 + 3x}{x} = \frac{68}{x}[/tex]

[tex] \sf multipy \: both \: sides \: by \: x : \\ \sf \implies (\frac{17 +3 x}{x} )x = (\frac{68}{x} )x \\ \implies \sf 17 + 3x = 68[/tex]

[tex] \sf cancel \: 17 \: from \: both \: sides : \\ \implies \sf 17 - 17 + 3x = 68 - 17 \\ \implies \sf 3x = 51[/tex]

[tex] \sf divide \: both \: side s \: by \: 3 : \\ \sf \implies \frac{3x}{3} = \frac{51}{3} \\ \therefore x = 17[/tex]

Answer:

x=2

Step-by-step explanation:

1*x+30=6x+20

Multiply 1*x=x

x+30=6x+20

Subtract 30 from both sides:

x+30-30=6x+20-30

Simplify:

x=6x-10

Subtract 6x from both sides

x-6x=6x-10-6x

Simplify:

-5x=-10

Divide both sides by -5

-5x/5=-10/-5

Answer:

Answer B

Step-by-step explanation:

Write out f(x) and g(x) in a column; we will subtract g(x) from f(x):

f(x) = x^2  - 9          or f(x)   =   x^2           - 9

-g(x) = -(2 - x)          or -g(x) =           +x      -2

                                    ---------------------------------

                                      f(x) - g(x) = x^2 + x - 11   (Answer B)

Step-by-step explanation:

This should be correct

Answer:

In this question (t½) of C-14 is 5730 years, which means that after 5730 years half of the sample would have decayed and half would be left as it is. After 5730 years ( first half life) 70 /2 = 35 mg decays and 35 g remains left. After another 5730 years ( two half lives or 11460 years) 35 /2 = 17.5mg decays and 17.5 g remains left . After another 5730 years ( three half lives or 17190 years) 17.5 /2 = 8.75mg decays and 8.75g remains left. after three half lives or 17190 years, 8.75 g of C-14 will be left.

Step-by-step explanation:

Answer:

$1,116.19.

Step-by-step explanation:

Given that artificial grass sells for $ 10.98 per square yard, to determine the final cost to buy and install 69.2 square yards if the seller charges $ 5.15 per square yard for labor, round to the nearest cent, the following calculation must be performed:

69.2 x (10.98 + 5.15) = X

69.2 x 16.13 = X

1,116,196 = X

Thus, the cost to purchase and install 69.2 square yards of artificial grass is $ 1,116.19.

Graph is on the picture.
