Answer:

x = 8. y = 21

Step-by-step explanation:

x + 8x + 18 = 90

combine like terms

9x + 18 = 90

-18 both sides

9x = 72

divide by 9 both sides

x = 8

______

3y + 27 = 90

-27 both sides

3y = 63

divide by 3 both sides

y = 21

The discount amount is $213.6

The sale price for the exercise machines is $676.4

The first step is to calculate the discount amount

890 × 24/100

= 890 × 0.24

= 213.6

The next step is to calculate the sale price

890(1-0.24)

890(0.76)

676.4

Hence the discount amount is $213.6 and the sale price of the exercise machine is $676.4

The number sentence 4.8 < √32 is true

A number sentence is an arrangement of numbers and mathematical operation symbols

Given:

For 3 1/3 < √7

3 1/3 = 3.33 and √7 = 2.65

3.33 < 2.65

This is not true

For 4.8 < √32

√32 = 5.66

4.8 < 5.66

This is true

For |-3.2| < |-3.1|

|-3.2| = 3.2                Note: when you see sign | | you neglect the sign

|-3.1| = 3.1

3.2 < 3.1

This is not true

For 5.3×10⁵ < 9.76× 10⁴

5.3×10⁵ = 5.3×100000 = 530000

9.76× 10⁴ = 9.76×10000 = 97600

If he  has allocated $67,050 for the cost of growing his crops. The number of acres of each crop that should  plant is Corn 270, Wheat 540, Soybeans 450.

Let c = corn

Let w = wheat

Let s = soybeans

C+W+S = 1260

45C + 60W + 50S = 67050

W =2C

Substitute equation 1 into equation 2

C + 2C +S = 1260

3C + S =1260

45C + 120C + 50S =67050

165C +50S =67050

Let eliminate S

165C+ 50(1260-3C) =67050

165C + 63000 - 150C= 67050

15C= 4050

Divide both side by 15c

c =4050/15

c = 270 (corn)

Wheat

W=2C

w = 2(270)

w= 540

S= 1260 - 3C

S= 1260- 3(270)

S =1260 -810

Answer:

46/273

Step-by-step explanation:

To add fractions, they must have a common denominator. To set one, find a common multiple of both denominators. Simply multiply them together if it proves difficult.

7 x 39 = 253

Now set the denominators to this number and multiply the numerators by the opposite fraction's denominator.

39/259 + 7/253 = 46/253
This simplifies to 2/11

So, 1/3 + 1/39 = 2/11

Aanya will now buy each at the cost below

A cherry muffin costs 350 shillings

A blueberry muffin costs 210 shillings

An apple costs 140 shillings

damson ones costs 70 shillings

The information given in the question is interpreted as below

A cherry muffin = 350 shillings

A blueberry muffin = 3 * damson ones

An apple + a blueberry muffin = 1 cherry muffin

A cherry muffin + 2 damson ones = 2 apple + 1 blueberry

from: 1 blueberry muffin, B = 3 * damson ones, D

D = B / 3

Also, An apple, A + B = 1 cherry muffin, C

A = C - B

C + 2D = 2A + B

substituting the values

350 + 2 * (B/3) = 2 * (350 - B) + B

350 + 2B/3 = 700 - 2B + B

collecting like terms

2B/3 + B = 700 - 350

5B/3 = 350

5B = 1050

B = 1050/5

B = 210

Solving for cost of apple

A = C - B = 350 - 210 = 140

Solving for the cost of the damson ones

D = B / 3 = 210 / 3 = 70

Answer: The probability that more than 12 of the entry forms will include an order is 0.624.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have:

The Magazine Mass Marketing Company has received 16 entries in its latest sweepstakes.

The probability that more than 12 of the entry forms will include an order can be found as:

P(X > 4) = 1 - P(X = 0) - P(X = 1) - P(X = 2) - P( X = 3) - P(X = 4)

P(X > 4) = 1 - P(X = 0) - P(X = 1) - P(X = 2) - P(X = 3) - P(X = 4)

P(X > 4) = 1 - 0.0009 - 0.0097 - 0.043 - 0.117 - 0.205

P(X > 4) =  0.624
