Answer:

37/200

Step-by-step explanation:

Event/Sample Space = .185 = 18.5%

Answer:

Step-by-step explanation:

If 37 people out of 200 people opened an e-mail, you can write it as 37/200.

The number above the bar is the numerator: 37

The number below the bar is the denominator: 200

Divide the numerator by the denominator to get fraction's value:

Val = 37 ÷ 200

Val = 0.185

To calculate the percent value:

0.185 =  (Calculate fraction's value.)

0.185 × 100/100 =  

(0.185 × 100)/100 =  (Multiply that number by 100.)

18.5/100 =

18.5%;  (Add the percent sign % to it.)

So that's how you get 18.5%

Answer: Your answer will be 1/2

Answer:

It would be C  , 7 root 2

Step-by-step explanation:

you would have to find the Sin of 45. So you set up a proportion ( you can do this on a calculator)

sin 45=7/x and then calculate that and solve.

If you dont have a calc then the sin of 45 is 1/root2

284 boxes in the shape of the cubes can be fitted in the truck.

If a truck is fitted fully with the cubes, volume of the truck will be equal to the volume of cubes to be fitted.

Dimensions of the truck given in the question,

Since, volume of a cuboid (shape of a truck) is given by the expression,

Volume = Length × Width × Height

Therefore, volume of the truck = 10 × 12 × 8

                                                   = 960 feet³

Volume of a cube is given by the expression,

Volume = (side)³

Therefore, volume of the cube with side length 1.5 feet will be,

Volume of a cube = (1.5)³

                              = 3.375 cubic feet

Let the number of cubes fitted in the truck = x

Therefore, volume of 'x' cubes = (3.375x) feet³

Since, volume of the truck = Volume of the cubes fitted

3.375x = 960

x = [tex]\frac{960}{3.375}[/tex]

x = 284.44

x ≈ 284

     Therefore, 284 boxes in the shape of the cubes can be fitted in the truck.

Answer:

We can fine x by using the pythagoras formula

a²+b² = c²

Which C is X

And

a= 17

b= 15

So

a² + b² = c²

(17)² + (15)² = c²

289 + 225 = c²

514 = c²

√514 = c

22.67 = c

So basically X is (22.671)

The missing side of the given right angled triangle is 8 units.

In the given right angled triangle, the hypotenuse side is 17 units, base is 15 units and the height is x units.

By using Pythagoras theorem, we get

17²=15²+x²

289=225+x²

x²=289-225

x²=64

x=√64

x=8 units.

Therefore, the missing side of the given right angled triangle is 8 units.

Answer: $34

Step-by-step explanation:

After 11 years,188.76 more money would Lincoln have in his account than Robert

percentage, a relative value indicating hundredth parts of any quantity.

Given,

Lincoln invested $440 in an account paying an interest rate of 7 ​% compounded continuously.

Robert invested $440 in an account paying an interest rate of 5 ​ %.

We need to find how much more money would Lincoln have in his account than Robert in 11 years.

[tex]A=Pe^{rt}[/tex]

For Lincoln:

P=440,

r=7%=0.07

t=11

A=440e⁰⁰⁷ˣ¹¹

A=440e⁰⁷⁷

A=949.96

For  Robert,

P=440,

r=5%=0.05

A=440e⁰⁰⁵ˣ¹¹

A=440e⁰⁵⁵

A=761.2

Now find the difference of Albert and Robert money

949.96-761.2

188.76

Hence, After 11 years,188.76 more money would Lincoln have in his account than Robert

Answer:

135 yards

Step-by-step explanation:

There are 135 yards in 45 feet.

Our information:

The park is 45 feet long

There is (3 feet= 1 yard)

Since there is 3 feet in 1 yard. You have to multiply 45 x 3.

So, The answer is 135 yards.

2*4^2+4-15=21

Step-by-step explanation:

The addition is one of the four fundamental mathematical operations. The two integers are 4 and 17.

The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.

Let the two unknown integers be represented by x and y, where x

Given that The sum of two integers is 21. Therefore, we can write,

x + y = 21

y = 21 - x

Also, Fifteen less than double the square of the smaller integer is equal to the larger integer.

2(x²) - 15 = y

Substitute the value of y from the first equation,

2(x²) - 15 = 21 - x

2x² - 15 = 21 - x

2x² + x - 15 - 21 = 0

2x² + x - 36 = 0

2x² + 9x - 8x - 36 = 0

x(2x + 9) -4(2x + 9) = 0

(x-4)(2x+9) = 0

x = (-9/2), 4

Since it is given that the number are integers, therefore, the only option is 4.

Further, the two integers are,

x = 4

y = 21 - x = 21 - 4 = 17

Hence, the two integers are 4 and 17.

Step-by-step explanation:

Answer:

1.)

A.) The graph does represent a proportional relationship because if you calculate the slope, it's 2/3, which is consistent throughout the line and with the given points.

Slope calculation:

[tex]\frac{y2-y1}{x2-x1} \\\\\frac{6-4}{9-6} \\\\\frac{2}{3}[/tex]

B.) The coordinate (0,0) represents that no laps have been completed nor has the time started

C.) The coordinate I chose is (6,4). It represents that 4 laps were completed in 6 minutes

2.) The values to represent a proportional relationship because once calculating the slope, which is 13, you can try it with other points. Even though there's some values missing between (6,78) and (10,130), the slope remains the same.

Slope Calculation:

[tex]\frac{y2-y1}{x2-x1} \\\\\frac{130-39}{10-3} \\\\\frac{91}{7} \\\\\frac{13}{1}[/tex]

3.)

A.) The constant of proportionality is 7/4 or 1.75

B.) y = 7/4x

4.) She'll run 8 miles because since 3/4 of an hour equates to 6 miles and there's 1/4 missing, 2 miles is 1/3 of 6 miles and 1/4 is 1/3 of 3/4 , so 1/4+1/4+1/4 = 3/4. She can run 8 miles (4*2) in 1 hour (4*1/4 hour)

Answer:

y < 1/4x + 6

Step-by-step explanation:

So the first thing I found was the slope so using rise over run you could see it was going down one and to the right 4 times which gave me 1/4 for the slope, then i needed to find the y intercept which was positive 6 I got I knew it was less than because it is shaded under the line and i knew it was less than opposed to less then or equal to because its a dotted line.  

So to make the equation we first do y = slope (x) + y intercept

(if your y intercept was -6 you would change the + to a -)

our slope is 1/4 so y = 1/4x

our y intercept is 6 so we get y = 1/4x + 6
