Answer:

B.The rate of change of function A is 2.

The rate of change of function B is 2.

Rate of function A: 2 (coefficient for x)

Rate of function B: 2, because an increment of 1 in x (e.g. 3 to 4) yields an increment of 2 in y (3 to 5)

Have a beautiful day!

Please help me 33/2 + 3y/5 = 7y/10 + 15

We are given with an equation in variable y and we need to solve for y . So , now let's start !!!

We are given with ;

${:\implies \quad \sf \dfrac{33}{2}+\dfrac{3y}{5}=\dfrac{7y}{10}+15}$

Take LCM on both sides :

${:\implies \quad \sf \dfrac{165+6y}{10}=\dfrac{7y+150}{10}}$

Multiplying both sides by 10 ;

${:\implies \quad \sf \cancel{10}\times \dfrac{165+6y}{\cancel{10}}=\cancel{10}\times \dfrac{7y+150}{\cancel{10}}}$

${:\implies \quad \sf 165+6y=7y+150}$

Can be further written as ;

${:\implies \quad \sf 7y+150=165+6y}$

Transposing 6y to LHS and 150 to RHS

${:\implies \quad \sf 7y-6y=165-150}$

${:\implies \quad \bf \therefore \quad \underline{\underline{y=15}}}$

Solve for 2. Round to the nearest tenth, if necessary.

UNO [17]

Answer:

x ≈ 94.4

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan58° = $\frac{LM}{KL}$ = $\frac{x}{59}$ ( multiply both sides by 59 )

59 × tan58° = x , then

x ≈ 94.4 ( to the nearest tenth )

Solve this problem. What is x? x ÷ 7 = 6 x =

So another way to look at is 7x6=__ and so when you do this you get 42. Hope this is helpful.

I need help on number 18

Answer:

Volume = 35185.8 $km^{3}$

Step-by-step explanation:

Recall the formula for the volume of a cone: $Volume = \pi R^{2} \frac{h}{3}$

Where R is the radius of the cone's circular base (in your case half of 80 km,(that is 40 km)

And h stands for the height of the cone (in your case 21 km)

We replace such in the formula and calculate its final value:

$Volume = \pi 40^{2} \frac{21}{3} = \pi 1600 \frac{21}{3} = \pi 1600 (7) = 35185.83772...$

We round it to the number of decimals your problem request (let's say to one decimal) and also include the cubic units:

Volume = 35185.8 $km^{3}$
