Answer:

y = -5x + 6

Step-by-step explanation:

y = 1/5 x + 4/5

so that two lines are perpendicular, its slope must be opposite and reciprocal

y = m x + b

m: slope perpendicular -1/m

if our formula is y = 1/5 x + 4/5

m = 1/5

so the slope of our new formula will be

m' = -5/1

m' = -5

now if you tell us that you have to go through a certain point (1/1)

we just have to replace the values in the following formula and solve

y - y1 = m ( x - x1)

y - 1 = -5 ( x - 1)

y = -5x + 5 + 1

y = -5x + 6

sashi weaves 25 baskets in 35 days how many days will it take for her to weave 110 baskets pls tell with steps

PtichkaEL [24]

Answer:

Step-by-step explanation:

If Sashi weaves 25 baskets in 35 days, let's find out how long it takes her to weave 1 basket.

25 baskets = 35 days

To find how long one basket takes, divide 35 by 25

1 basket = 35/25 = 1.4 days

Next to find how many days it takes for her to weave 110, you just multiply by 110 since we know it takes her 1.4 days to weave 1 basket.

110 baskets = 1.4 times 110 = 154 days.

A universal set U consists of elements. If sets A, B, and C are proper subsets of U and n(U), n(A B)n(A C)n(B C), n(A

iragen [17]

Answer:

$n(A\ u\ B) = 10$

$n(A'\ u\ C) = 10$

$n(A\ n\ B)' = 6$

Step-by-step explanation:

Given

$n(U) = 12$

$n(A\ n\ B) =n(A\ n\ C) = n(B\ n\ C) =6$

$n(A\ n\ B\ n\ C)=4$

$n(A\ u\ B\ u\ C)=10$

Required

Solve a, b and c

There are several ways to solve this; the best is by using Venn diagram (see attachment for diagram)

Solving (a):

$n(A\ u\ B)$

This is calculated as:

$n(A\ u\ B) = n(A) + n(B) - n(A\ n\ B)$

From the attachment

$n(A) = 0+2+4+2 = 8$

$n(B) = 0+2+4+2 = 8$

$n(A\ n\ B) = 4 +2 = 6$

So:

$n(A\ u\ B) = 8 + 8 - 6$

$n(A\ u\ B) = 10$

Solving (b):

$n(A'\ u\ C)$

This is calculated as:

$n(A'\ u\ C) = n(A') + n(C) -n(A'\ n\ C)$

From the attachment

$n(A) = n(U) - n(A) = 12 - 8 = 4$

$n(C) = 0+2+4+2 = 8$

$n(A'\ n\ C) = 2$

So:

$n(A'\ u\ C) = 4 + 8 - 2$

$n(A'\ u\ C) = 10$

Solving (c):

$n(A\ n\ B)'$

This is calculated as:

$n(A\ n\ B)' = n(U) - n(A\ n\ B)$

$n(A\ n\ B)' = 12- 6$

$n(A\ n\ B)' = 6$

Mark used a number line to model dividing 2 3 by 3. He divided the number line from 0 to 1 in 3 equal sections, and then divided

Oxana [17]

Answer:

No, his answer is not correct.

Step-by-step explanation:

Given expression,

$\frac{2}{3}\div 3$

$=\frac{\frac{2}{3}}{3}$

$=\frac{2}{3\times 3}$

$=\frac{2}{9}$

Thus, his answer is not correct.

By model :

Draw number line from 0 to 1 in 3 equal section,

Then divided each of those sections into 3 equal parts,

We get,

$\frac{2}{3}\div 3=\frac{2}{9}$
