Answer:

C. (2, 1)

Step-by-step explanation:

-3y = x-5

x+ 5y = 7

Subtract x from both sides in the first equation. Write the second equation below it.

-x - 3y = -5

x + 5y = 7

Add the two equations above.

2y = 2

Divide both sides by 2.

y = 1

Substitute y with 1 in the second original equation and solve for x.

x + 5(1) = 7

x + 5 = 7

Subtract 5 from both sides.

x = 2

Calculate the area of the shaded sector in the circle

scZoUnD [109]

Answer:

area ≈ 6.3 units²

Step-by-step explanation:

Calculate the area (A ) of the sector as

A = area of circle × fraction of circle

= πr² × $\frac{45}{360}$

= π × 4² × $\frac{1}{8}$

= 16π × $\frac{1}{8}$ ← cancel 8 and 16 by 8, leaving

A = 2π ≈ 6.3 units² ( to 1 dec. place )

Which of the following is the surface area of the right cylinder below radius 7 height 2

juin [17]

$\bf \textit{surface area of a cylinder}\\\\ SA=2\pi r(h+r)~~ \begin{cases} r=radius\\ h=height\\ -----\\ r=7\\ h=2 \end{cases}\implies SA=2\pi (7)(2+7) \\\\\\ SA=14\pi (9)\implies SA=126\pi$

A certain motorcycle manufacturer has been building motorcycles for 98 years. Over that period, production has increased steadil

Reika [66]

Answer: The fraction would be 0.53.

Step-by-step explanation:

Since we have given that

$r(t)=A.(1.05)^t$

where, A is the constant initial production rate

t is the time.

For 98 years, the production rate in motorcycles per year would be

$r(98)=A.(1.05)^{98}\\\\r(98)=A.119.27$

For 13 years, the production rate in motorcycles per year would be

$r(98-13)=r(85)=A.(1.05)^{85}\\\\r(85)=A.63.25$

So, the fraction of their total production was built during the last 13 years would be

$\dfrac{r(85)}{r(98)}=\dfrac{63.25}{119.27}=0.53$

Hence, the fraction would be 0.53.
