could u also look at my other question ty ILL GIVE U BRAINLIEST AND 20 POINTS

Answer:

a = 90

b = 28

c = 68

d = 22

Step-by-step explanation:

[tex]a = 90[/tex]

[tex]d=22[/tex]

[tex]22+90=112[/tex]

[tex]180-112=68[/tex]

[tex]c=68[/tex]

[tex]62+90=152[/tex]

[tex]180-152=28[/tex]

[tex]b=28[/tex]

the ratio is

2 : 5 , or 40 : 100

sorry if this is wrong, i tried my best.

Answer:

Weight of dried bananas = 34.75 kg

Weight of dried apricot = 15.25 kg

Step-by-step explanation:

Given that:

Cost of dried bananas = $4.59 per kg

Cost of dried apricots = $6.59 per kg

Total weight of mixture = 50 kg

Sales price of dried fruit = $5.20 per kg

To find:

The weight of each type of dry fruit = ?

Solution:

Let weight of dried bananas = [tex]x[/tex] kg

Let weight of dried apricot = [tex]y[/tex] kg

[tex]x+y=50 ...... (1)[/tex]

Total cost of dried bananas = Cost of dried bananas per kg multiplied by weight of dried bananas

Total cost of dried bananas = $4.59[tex]x[/tex]

Total cost of dried apricots = Cost of dried apricots per kg multiplied by weight of dried apricots

Total cost of dried apricots = $6.59[tex]y[/tex]

As per question statement,

Total cost of dry fruits = $5.20 [tex]\times[/tex] 50 = $260

[tex]260 = 4.59x+6.59y......(2)[/tex]

Using substitution:

By equation (1):

[tex]x = 50-y[/tex]

Putting in equation (2):

[tex]260 = 4.59 (50-y)+6.59y\\\Rightarrow 2y = 260 - 229.5\\\Rightarrow y = 15.25\ kg[/tex]

[tex]x = 50 - 15.25\\\Rightarrow x = 34.75\ kg[/tex]

Therefore, the answer is:

Weight of dried bananas = 34.75 kg

Weight of dried apricot = 15.25 kg

Answer: y=2x+4 for parallel and y=-1/2x+1 1/2

Step-by-step explanation: you need to do an equation using the slope which you can find by using y2-y1/x2-x1

from there you have to use y-y1=m(x-x1)

Answer:

8 ft^2

Step-by-step explanation:

Since the area of the circle is pi*radius^2, we can plug the values in and get that the area of the circle is 3.14 (approx.) * (6/3)^2, which equals to 3.14*9 ft^2, which equates to 28.26 ft^2.

Hence, the exact area left is 36 - 28.26 ft^2 = 7.74 ft^2, which is closest to 8 ft^2.

Step-by-step explanation:

Answer: On Monday the town got 2 3/4 (2.75) inches of snow.

On Tuesday it got 1 1/2 (1.5) times as much: 2.75 x 1.5 = 1.375 (inch)

⇒ On Tuesday the town got 1.375 inch of snow.

On Wednesday it got 7/8 (0.875) inch of snow.

After Monday, Tuesday and Wednesday, the town got:

2.75 + 1.375 + 0.875 = 5 (inches of snow)

For the rest of the week, the town got:

15 1/2 - 5 = 10 1/2 = 10.5 (inches of snow)

Step-by-step explanation: hope it helped :))

Answer:

7.76 inches, and this is NOT including Saturday and Sunday

Step-by-step explanation:

Monday: 2.75 inch

Tuesday: 2.75 * 1.5 = 4.12 inches

Wednesday: 7/8 = .87 inches

So, you add

2.75 + 4.12 + .87 = 7.74 inches for Mon, Tues and Wed.

then 15.50 - 7.74 = 7.76 inches of snow for both Thurs and Friday

Hope it Helps!

Answer:

could you posibly put a pic

Step-by-step explanation:

9514 1404 393

Answer:

Step-by-step explanation:

The graph shows price decreases with age, so the minimum price will be associated with cars that are 3 years old. We read from the graph that the price of a 3-year-old car is about $11,600. (This is slightly more than halfway between the $11,000 and $12,000 grid lines.)

The maximum will be associated with a 2-year-old car. We can read the graph to find the price of a 2-year-old car is $14,000. That value is on the grid line, so no guessing is necessary.

Then we have ...

  minimum: $11,600

  maximum: $14,000

_____

Additional comments

We'd like to check our guess of the minimum using the given price equation. Filling in x=3 in the equation, we get ...

  2400·3 +6800 = 7200 +6800 = 14,000 . . . . matches the maximum, not the minimum

We observe that the equation has a positive coefficient for x, so will be the equation of a rising line, not the falling one shown on the graph.

For "fun", we can check to see what the equation gives for x=2:

  2400·2 +6800 = 4800 +6800 = 11,600 . . . . matches the minimum, not the maximum

This gives us some confidence that our choice of numbers is correct, but makes it clear that the equation is incorrectly written.

The problem needs to be reported, so it can be fixed.

x2 - 81

Trying to factor as a Difference of Squares:

1.1 Factoring: x2 - 81

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 81 is the square of 9

Check : x2 is the square of x1

Factorization is : (x + 9) • (x - 9)

Simplify —————————————

x2 - 6x - 27

Trying to factor by splitting the middle term

2.1 Factoring x2 - 18x + 81

The first term is, x2 its coefficient is 1 .

The middle term is, -18x its coefficient is -18 .

The last term, "the constant", is +81

Step-1 : Multiply the coefficient of the first term by the constant 1 • 81 = 81

Step-2 : Find two factors of 81 whose sum equals the coefficient of the middle term, which is -18 .

-81 + -1 = -82

-27 + -3 = -30

-9 + -9 = -18 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -9 and -9

x2 - 9x - 9x - 81

Step-4 : Add up the first 2 terms, pulling out like factors :

x • (x-9)

Add up the last 2 terms, pulling out common factors :

9 • (x-9)

Step-5 : Add up the four terms of step 4 :

(x-9) • (x-9)

Which is the desired factorization

Trying to factor by splitting the middle term

2.2 Factoring x2-6x-27

The first term is, x2 its coefficient is 1 .

The middle term is, -6x its coefficient is -6 .

The last term, "the constant", is -27

Step-1 : Multiply the coefficient of the first term by the constant 1 • -27 = -27

Step-2 : Find two factors of -27 whose sum equals the coefficient of the middle term, which is -6 .

-27 + 1 = -26

-9 + 3 = -6 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -9 and 3

x2 - 9x + 3x - 27

Step-4 : Add up the first 2 terms, pulling out like factors :

x • (x-9)

Add up the last 2 terms, pulling out common factors :

3 • (x-9)

Step-5 : Add up the four terms of step 4 :

Answer:

7/10ths

Step-by-step explanation:

There are ten blocks all together, which is where the 10 comes from, there is 7 shaded that is where the 7 comes from.

Answer:

The percentage is 70%.

Step-by-step explanation:

There are 10 spaces total, and 7 are shaded in. 7 divided by 10 is 0.7.

0.7 as a percentage is 70%.

So 70% of the block is shaded in.

Answer:

12 crossed by 3

Step-by-step explanation:

Answer:

The correct unit price is $1.17 per pair of gloves. The error is she used number of dozens so, firstly convert it to number of pairs of gloves then divide.

Step-by-step explanation:

It is given 4 dozen pairs of gloves for $56.16.

So, unit price = Divide the price by number of pairs of gloves.

And 1 dozen =12

So 4 dozen =4*12=48 pairs of gloves

So, to find unit rate divide 56.16  by 48.

Unit price =[tex]\frac{56.16}{48}= $1.17[/tex]

So, the error is she didn't convert the dozen to units.

That made mistake in finding unit price.

Step-by-step explanation:

5x -2

Answer choices:

a. 2-5x

b. 3-5 +2x

c. 5x-2x

d. 2x-2+3x

a.

2-5x can be rewritten as -5x+2, which is not the same as 5x-2

b. 3-5 + 2x can be rewritten as -2 + 2x or 2x-2 which is not equivalent to 5x-2

c. 5x-2x is 3x

3x doesn't equal 5x-2

d. 2x+3x-2 = 5x-2

This expression is equivalent to 5x-2

No, I think it has 2 solutions.
