Mathematics
1 answer:
zhuklara [117]3 years ago
6 0

Answer:

Surface area of cuboid = 352 cm

Step-by-step explanation:

Given that:

Height of cuboid = 8 cm

Length of cuboid = 12 cm

Width of cuboid = 4 cm

Surface area = 2lw + 2lh + 2hw

Putting all the values;

Surface area = 2*12*4 + 2*12*8 + 2*8*4

Surface area = 96 + 192 + 64

Surface area = 352 cm

Hence,

Surface area of cuboid = 352 cm

hram777 [196]

Given:

An elevation of - 12 m is higher than an elevation of -17 m.

An elevation of - 17 m is lower than an elevation of -14 m.

To find:

The set of inequalities that correctly expresses these relationships.

Solution:

An elevation of - 12 m is higher than an elevation of -17 m.

We know that, higher than means greater than and it is represented by the inequality ">". So,

-12>-17

An elevation of - 17 m is lower than an elevation of -14 m.

We know that, lower than means less than and it is represented by the inequality "<". So,

-17

Therefore, the required set of inequalities is -12>-17 and -17.

Note: The inequality signs are not proper in the options.

7100 dollars is placed in an account with an annual interest rate of 5%. To the nearest tenth of a year, how long will it take f
kow [346]

Answer:

After 26.91\ years the principle amount value will reach to 26400\ dollars.

Step-by-step explanation:

Given that,

                 Principle Amount (P)= 7100\ dollars

                 Rate of Interest (R)= 5%

                 Total Amount (A)= 26400\ dollars

If Principle Amount (P) =P\ dollars, Time =t\ years, Rate of Interest =R% pa

when interest is compounded annually:

Total Amount after t\ years = P(1+\frac{R}{100}) ^{t}

Now,

         A= P(1+\frac{R}{100}) ^{t}

     ⇒ 26400=7100(1+\frac{5}{100}) ^{t}

     ⇒ 3.7183=(1+0.05)^{t}

     ⇒ 3.7183=(1.05)^{t}

taking log both sides, we get

         ln(3.7183)=ln {(1.05)^{t}}

     ⇒ 1.31327=t\times ln(1.05)

     ⇒ 1.31327=t\times 0.04879

    ⇒ t=26.91

Therefore,

After 26.91\ years the principle amount value will reach to 26400\ dollars.

Using the information that you've provided, I would say that Mr. Banks drove home at 5:15, but if you're asking what time he arrived home that would be at 6:30. :))
