Alla [95]3 years ago

4 0

Answer:

253,000

Step-by-step explanation:

$10^{5} = 100000$
$10^{4} = 10000$
Plug the above answers in: 2.1 × 100,000 + 4.3 × 10,000
2.1 × 100,000 = 210,000
Plug 210,000 in: 210,000 + 4.3 × 10,000
4.3 × 10,000 = 43,000
Plug 43,000 in: 210,000 + 43,000
210,000 + 43,000 = 253,000

I hope this helps!

Eric, Cam, and Brooke are playing a game of mini golf on a computer. The computer program for the game stores

andrew-mc [135]

Answer:

Eric

Step-by-step explanation:

First, we determine the distance of each player to the hole using the distance formula.

Given points $(x_1,y_1)$ and (x_2,y_2)$

Distance $=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Eric

The hole is at (3,2)

Eric's golf ball is at point (-6,6)

Distance= $\sqrt{(-6-3)^2+(6-2)^2}$

$=\sqrt{(-9)^2+(4)^2}\\=\sqrt{97} \\\approx 9.85$

Cam

The hole is at (3,2)

Cam's golf ball is at point (8,-6)

Distance= $\sqrt{(8-3)^2+(-6-2)^2}$

$=\sqrt{(5)^2+(-8)^2}\\=\sqrt{89} \approx9.43$

Brooke

The hole is at (3,2)

Brooke's golf ball is at point (10,8)

$Distance=\sqrt{(10-3)^2+(8-2)^2}\\=\sqrt{(7)^2+(6)^2}\\=\sqrt{85} \approx 9.22$

Since Eric's ball is the farthest from the hole, Eric should shoot next.

Draw fraction rectangles on dot paper to solve the problems.

juin [17]

Answer:

1) $\frac{7}{20}$

2) $1\frac{1}{12}$

3) $\frac{7}{8}$

Step-by-step explanation:

1) Given problem,

$\frac{3}{5}-\frac{1}{4}$

LCM(5,4) = 20,

$\frac{3}{5}=\frac{3\times 4}{5\times 4}=\frac{12}{20}$

$\frac{1}{4}=\frac{1\times 5}{4\times 5}=\frac{5}{20}$

$\implies \frac{3}{5}-\frac{1}{4}=\frac{12}{20}-\frac{5}{20}=\frac{7}{20}$

2) Given problem,

$\frac{5}{6}+\frac{1}{4}$

LCM(6, 4) = 12,

$\frac{5}{6}=\frac{5\times 2}{6\times 2}=\frac{10}{12}$

$\frac{1}{4}=\frac{1\times 3}{4\times 3}=\frac{3}{12}$

$\implies \frac{5}{6}+\frac{1}{4}=\frac{10}{12}+\frac{3}{12}=\frac{13}{12}=1\frac{1}{12}$

3) ∵ Pizza ate by Manny = $\frac{1}{4}$

Pizza ate by Frank = $\farc{5}{8}$

∴ Total pizza eaten = $\frac{1}{4}+\frac{5}{8}$

LCM(4, 8) = 8,

$\frac{1}{4}=\frac{2}{8}$

Thus, total pizza eaten = $\frac{2}{8}+\frac{5}{8}=\frac{7}{8}$
