computers?

Answer:

y = 1/2 x  - 4

Step-by-step explanation:

Given the equation of the line as 2x+y = 1

Get the slope

y = -2x+1

Slope of the line is m = -2

Slope of the line P will ne M = -1/-2 (since they are perpendicular)

Slope of line P = 1/2

The equation in point slope form is expressed as;

y - y 0 = m(x-x0)

Given that x0 = 10, y =  1

y - 1 = 1/2(x-10)

2(y-1) = x-10

2y - 2 = x-10

2y = x - 10 +'2

2y = x-8

y = 1/2 x - 8/2

y = 1/2 x  - 4

This gives the equation of line P

36=6+6+6+6+6+6=6X6

36=4+4+4+4+4+4+4+4+4=4X9

36=18+18=18X2

37=18,5+18,5=18,5X2

37=9,25+9,25+9,25=9,25X4

38=19+19=19X2

38=9,5+9,5+9,5+9,5=9,5X4

Answer:

2

a) 6.37%

b) 6.25%

3

a) 0.60 %

b) 0.59 %

Step-by-step explanation:

2 )

a) With replacement

Probability of extracting a club is 13/52

Probability of extracting a spade is 13/51

13/52 * 13/51

= 6.37 %

b) Without replacement

13/52 * 13/52

= 6.25 %

3) With replacement

Probability of extracting a ace is 4/52

Probability of extracting a queen is 4/51

4/52 * 4/51

= 0.60 %

b) Without replacement

4/52 * 4/52

= 0.59 %

Actually Welcome to the Concept of the Profit and loss.

Since, in the comparison for the better buy than the 4 boxes for $3.79 is

Option A.) 6 for $5.75

because all other three are costlier than the their original price,

also, 3.79/4 = $0.94

if, $0.94 * 6 = $5.685

so, $5.685 means,the the buy is better that original price.

Answer:

[tex] r = \frac{12\sin 20\degree}{ \sin 35\degree } [/tex]

Step-by-step explanation:

By sine rule

[tex] \frac{r}{ \sin \angle R } = \frac{p}{ \sin \angle P} \\ \\ \frac{r}{ \sin 20\degree } = \frac{12}{ \sin 35\degree } \\ \\ r = \frac{12\sin 20\degree}{ \sin 35\degree } [/tex]

ℹ️we have to find base area of the given pyramid first..ℹ️

▶️ let the base of the pyramid be "x"

▶️ x = width of the base × length of the base

▶️ x = 16 × 14

▶️ x = 224

hence the base is 224.. Now ,

▶️ volume of pyramid = 1/3 × base area × height

▶️ volume of pyramid = 1/3 × 224 × 16

▶️ volume of pyramid = 1120³

Answer:

1. A 2.D

Step-by-step explanation:

G is the number of girls who attended so that will be our product.

Since 75% of the girls attended the dinner and there are 12 girls on the team we are trying to find a part of the team that attended the dinner so

we would multiply a decimal times the whole.

Convert 75% into a decimal

[tex] \frac{75}{100} = 0.75[/tex]

Multiply that by 12 to equal G

[tex]0.75(12) = g[/tex]

So the answer is A

Kim pick 2 1/3 lbs every 1/4 hour. We are asked how many she pick every hour.

Let set up a fraction to make the equation equivalent

[tex] \frac{2 \frac{1}{3} }{ \frac{1}{4} } = \frac{x}{1} [/tex]

1/4 goes into 1 4 times. so we would multiply 4 by 2 1/3 to find the x value.

[tex] 2\frac{1}{3} \times 4[/tex]

[tex]2 \frac{1}{3} \times \frac{12}{3} [/tex]

[tex] \frac{7}{3} \times \frac{12}{3} [/tex]

[tex] \frac{84}{9} [/tex]

[tex]9 \frac{3}{9} [/tex]

[tex] 9\frac{1}{3} [/tex]

so the answer is D

Answer:

Step-by-step explanation:

x = 12

the triangle was made smaller (i forget what the term is)

it was made smaller by  [tex]1\frac{1}{3}[/tex]

to find that you divide 24 by its equivalent side on the other triangle which would be 18

24 / 18 =  [tex]1\frac{1}{3}[/tex]

to find what x is equal to you have to find the equivalent side on the other triangle. this would be 16. since the triangle with 16 is bigger the equation is:

16 / [tex]1\frac{1}{3}[/tex] = 12

so x = 12

Answer:

the answer is c for Friday and 6 3/12 hours for them both combined

Step-by-step explanation:

because 3 5/12 is closest to 3 1/2=3 6/12

for fir day and Saturday day combined it would be 6 3/12

because 5/6 is 10/12 and 5/12 + 10/12 is 15/12 which is also 1 3/12

so add 3 +2=5 and then add the fraction 1 3/12 which would be 6 3/12 hours

Answer:

24 Pepperoni pizza

Step-by-step explanation:

v = veggie

p = pepperoni

c = combo

v+p+c=112

p-8 = v

3p=c

substitute both values in equation above, thus,

p-8+p+3p = 112

5p-8=112

5p=120

p=24

Answer:

74.24ft tall, you were right!

Step-by-step explanation:

13.5/18 = 0.75

This is the ratio of shadow by actual height that you will use to find the height of the silo so now you multiply:

99*0.75 = 74.25

74.25 is the exact measurement of the taller silo's height.
