A cartographer is painting a spherical globe whose surface is 326.7 sq. in. What is the maximum radius of the globe that the car

KengaRu [80]

Answer:

(A)5.1 in.

Step-by-step explanation:

Surface Area of a Sphere $=4\pi r^2$

If the spherical globe has a surface area of 326.7 sq. in., then:

$4\pi r^2=326.7, \pi=3.14\\4*3.14* r^2=326.7\\r^2=326.7 \div 12.56\\r=\sqrt{326.7 \div 12.56} \\r=5.1$ inch$

The maximum radius of the globe that the cartographer is painting is 5.1 inches.

The correct option is A.

5 What rate of interest is paid on a deposit of $2000 which earns $400<br> interest in 5 years?

marishachu [46]

Answer:

Step-by-step explanation:

Given

I = 400
P = 2000
R = ?
T = 5 years

Formula

I = PRT

Solving.

I = PRT
400 = 2,000 × R × 5
400 = 10,000 × R
400 / 10,000 = R
0.04 = R

Change 0.04 to percent

0.04 × 100 = 4%

Distance between -3,-2 and 5,2

irakobra [83]

We can find the distance between two points by using distance formula,

$\qquad \: D = \sf \red{\sqrt{ {(x_2 -x_1)}^{2} + {(y_2 -y_1)}^{2} }}$

Here,

x₁ = -3

x₂ = 5

y₁ = -2

y₂ = 2

Therefore,

$: \implies \: D = \sf \red{\sqrt{ {(x_2 -x_1)}^{2} + {(y_2 -y_1)}^{2} }} \\ \\ : \implies \: D = \sf \sqrt{ {(5-( - 3))}^{2} + {(2 -( - 2))}^{2} }\\ \\ : \implies \: D = \sf \sqrt{ {8}^{2} + {4}^{2} } \\ \\ : \implies \: D = \sqrt{64 + 16} \\ \\ : \implies \: D = \sqrt{80}$

Hence the √80 = 8.94 approx is the distance between the two points (-3,-2) and (5,2).

Maria cut 3/4 yard of ribbon into pieces that are 1/8 yard long. How many pieces of ribbon did Maria cut? don't be a b.*.t.c.h.

Akimi4 [234]

<h3>Answer: 6 pieces</h3>

===============================================

Explanation:

3/4 = 6/8 after multiplying top and bottom of the fraction by 2

She has 6/8 of a yard of ribbon.

If she cuts the ribbon into pieces of 1/8 of a yard each, then she has 6 pieces overall

We can see this if we solve the equation (1/8)x = 6/8. Multiply both sides by 8 to get x = 6.
