Which linear inequality represents the graph below?

Mathematics

1 answer:

Cerrena [4.2K]3 years ago

6 0

Answer:

Step-by-step explanation:

1. We can clearly see that the "rise" is 5 and the "run" is 2, which cancels out both A. and D.

2. The line is dashed, which therefore cancels out both C. and D.

3. Just by canceling out those two can help you see that B fits what is seen in this figure because option A. has the wrong amount of "rise" over "run".

The number a is smaller than the number b by 1/5 of b. By what part of a is b bigger than a?

Ira Lisetskai [31]

Answer:

The number b is bigger than the number a by $\dfrac{1}{4}$ of a.

Step-by-step explanation:

1. If the number a is smaller than the number b by 1/5 of b, then

$a+\dfrac{1}{5}b=b.$

Thus,

$a=b-\dfrac{1}{5}b=\dfrac{4}{5}b,\\ \\b=\dfrac{5}{4}a.$

2. Consider the expression $b=\dfrac{5}{4}a:$

$b=\dfrac{5}{4}a=\dfrac{4}{4}a+\dfrac{1}{4}a=a+\dfrac{1}{4}a.$

This gives you that the number b is bigger than the number a by $\dfrac{1}{4}$ of a.

Jaina and Tomas compare their compound interest accounts to see how much they will have in the accounts after three years. They

stellarik [79]

Formula for compound interest is

Interest = Amount - Principal

Interest = $P(1+r)^{t}$ - P

Where r = rate in percent

t = time in years

For Jaina,

P = $300

r= 7%

t = 3 yrs

So, Interest = $300(1+0.07)^{3}$ - 300

For Tomas

P = $400

r= 4%

t = 3 yrs

So, Interest = $400(1+0.04)^{3}$ - 400

So pair of equations for Jaina and Tomas are

Interest = $300(1+0.07)^{3}$ - 300

Interest = $400(1+0.04)^{3}$ - 400

How can we find the volume of a cone? explain in brief .

densk [106]

$\sf volume \ of \ cone = \dfrac{1}{3} \pi r^2h$ ** where "r" is radius and "h" is height **

$\sf volume \ of \ cylinder= \pi r^2h$

$\boxed{ \sf \tfrac{1}{3}}$ as it refers to the volume of cone being 1/3 of the the volume of cylinder

Hardest, example:

given height of cone is 69 km and radius is 48 km

using the formula:

$\hookrightarrow \sf volume \ of \ cone = \dfrac{1}{3} \pi (48)^2(69)$

$\hookrightarrow \sf volume \ of \ cone = 52992\pi$

$\hookrightarrow \sf volume \ of \ cone = 166479.3 \ km^3$
