Answer:

[tex]32\:\mathrm{in}[/tex]

Step-by-step explanation:

The area of a triangle is given by [tex]A=\frac{1}{2}\cdot b\cdot h[/tex].

Substituting given values, we have:

[tex]240=\frac{1}{2}\cdot b\cdot 15,\\480=15b,\\b=\frac{480}{15}=\boxed{32\:\mathrm{in}}[/tex]

Answer:

Base=32 inches

Step-by-step explanation:

Area=240

Height= 15

Area= b*h/2

2A/h=b

2*240/15=b

b=32

Answer:

1) 2400 sq feet

2) $93.75

3) A (first answer)

Step-by-step explanation:

1) replace the 6 inches with 60 feet and 4 inches with 40 feet. We do this bc 1 inch = 10 feet. Then multiply 60 x 40 to get 2400 sq feet

2) we know that 25% off of 100 is 75. Then to add 25% back to 75 we find 25% of 75. 25% of 75 is 18.75. So we add 18.75 + 75 to get $93.75

Answer:

Lateral surface area of can = 47 inch² (Approx.)

Step-by-step explanation:

Given:

Diameter of given can = 3 inches

Height of given can = 5 inches

Find:

Lateral surface area of can

Computation:

Radius of can = 3 / 2 = 1.5 inch

Lateral surface area of can = Lateral surface area of cylinder

Lateral surface area of cylinder = 2πrh

Lateral surface area of can = 2πrh

Lateral surface area of can = 2(3.14)(1.5)(5)

Lateral surface area of can = 47.1

Lateral surface area of can = 47 inch² (Approx.)

Answer:

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set.)

Answer:

a. 26

Step-by-step explanation:

The formula for depreciation is given as

y = a(1 - r)^t

a = Initial value = $15,500

y = Current value = 1/10 of Initial value = $1,550

r = depreciation rate = 8.5% = 0.085

t = time in years = ?

Hence,

1550 = 15500(1 - 0.085)^t

1550 = 15500(0.915)^t

Divide both sides by 15500

1550/15500 =(0.915)^t

0.1 = (0.915)^t

Take the Logarithm of both sides

log 0.1 = log(0.915)^t

log 0.1 = t log (0.915)

Divide both sides by log 0.915

t = log 0.1/log 0.915

t = 25.920900964 years

Approximately Time t = 26 years

Option a is correct

Step-by-step explanation:

[tex]6x+5.5=3x-8\\[/tex]

[tex]6x-3x=-8-5.5[/tex]

[tex]3x=-13.5[/tex]

[tex]x=\frac{-13.5}{3}[/tex]

[tex]x=-4.5[/tex]

The value of x in the figure which illustrates similar triangles is 3

The figure illustrates similar triangles.

This is represented by the following equivalent ratios

x : 6 = 4 : 8

Express as fraction

x/6 = 4/8

Multiply both sides by 6

x = 6 * 4/8

Evaluate the product

x = 3

Hence, the value of x in the figure is 3

Answer:

7hr 12 min

Step-by-step explanation:

Given that

Bob  can type 2 letters in 4 hours

while on the other hand bill can do it in six hours

We need to find out the no of hours in which they type 6 hours

So,

Bob's rate is

= 2 ÷ 4

= 1 ÷ 2 letter per hour

And,  

Bill's rate is

= 2 ÷ 6

= 1 ÷ 3 letter per hour

Now

Together rate is

= 1 ÷ 2 + 1 ÷ 3 = 5 ÷ 6 letter per hour

We know that

rate × hours = production

Let us assume the hours be x

So,  

(5 ÷ 6)x = 6

x = (6 ÷ 5) × 6

x = 36 ÷ 5

= 7 1 ÷ 5

= 7hr 12 min

Answer:

100 sq units

Step-by-step explanation:

hypotenuse of the right triangle is the length of the square and we can find it by using the Pythagorean Theorem:

6² + 8² = c²

c² = 36+64

c² = 100

c = √100

c = 10

Area of square = 10² = 1--

Answer:

the additive inverse of 12 is -12

Step-by-step explanation:

The angle m∠CBE between the intersection of the chord and tangent line is equal to 41°

To calculate for the angle between the intersection of a chord and a tangent we need to know the measure of the intercepted arc, and then divide it by 2 to get the angle.

If the measure of the arc CAB is given to be equal to 278°, then the measure of intercepted arc BC is calculated as:

arc BC = 360 - 278

arc BC = 82°

angle CBE = 82°/2

m∠CBE = 41°

Therefore, the angle m∠CBE between the intersection of the chord and tangent line is equal to 41°

Answer:

mean = 2

median = 2.5

Step-by-step explanation:

There are a total of 20 goals  (1*0 + 3*1 + 1*2 + 3*5 = 0 + 3 + 2 + 15 = 20)

There are 10 games, so 20/10 = 2 = mean

Threre are 5 games with goals greater than 2.5 and 5 games with goals below 2.5.  So the median is 2.5
