Building a is 190 feet shorter than building

Mathematics
1 answer:
MaRussiya [10]3 years ago

We will solve this using a system of equations.  The first part tells us that building a is 190 feet shorter than building b.  Our first equation, then, is b=190+a.  The second part tells us that the addition of the two buildings' heights is 1480.  So our second equation is a + b = 1480.  The first equation is already solved for b, so let's sub that value into the second equation for b: a+(190+a)=1480.  2a + 190 = 1480 and 2a = 1290.  That means that building a is 645 feet tall.  Building b is 190 feet taller, so b = 190 + 645, which is 835.

What is the square of 8 step by step​
Marysya12 [62]

Step-by-step explanation:

Here is a helpful method I taught my students in my mini lesson...

For you to remember, 22= 4, and 32= 9. Hence the answer to the root of 8 lies between the numbers 2 and 3. However, since the square of 3 equals to 9 which is larger than 8, the root 8 value lies in between the number 2.8 and 2.9.

The volume of the tank can be obtained using the relation :

Volume = Length * width * height

Volume = (1/2 * 1/6 * 1/3) ft³

Volume = 1 / 36 ft³

The diagram shows a right-angled triangle.
Otrada [13]

Answer:

h ≈ 9.9 cm

Step-by-step explanation:

By applying tangent rule for the given angle in the given right triangle,

tan(51°) = \frac{\text{Opposite side}}{\text{Adjacent side}}

tan(51°) = \frac{h}{8}

h = 8 × tan(51°)

h = 9.879

h ≈ 9.9 cm

Therefore, measure of side 'h' is 9.9 cm.
