Answer:

Decimal form = 2.4 / Fraction form = 1/4

Step-by-step explanation:

We know that the farmer sold 9.6 kilograms of apples and pears where 3/4 of that weight was apples. That means that 1/4 of the 9.6 kilograms were pears. Lets divide 9.6 by 1/4 to get our answer.

9.6 / 1/4 = 2.4

Decimal form = 2.4

Fraction form = 1/4

Answer:

50

Step-by-step explanation:

The sum of the angles of a triangle is 180

A +B +C = 180

90 +4x+ 7x-20 =180

Combine like terms

70+ 11x = 180

Subtract 70 from each side

70-70+11x = 180-70

11x=110

Divide each side by 11

11x/11= 110/11

x = 10

We want to find angle C

C = 7x-20

   = 7*10-20

   = 70-20

   = 50

Answer:

50°

Step-by-step explanation:

7x - 20 + 4x + 90 = 180

11x = 180 - 70

11x = 110

x = 10

ACB: 7(10) - 20 = 50

Answer:

x=2

Step-by-step explanation:

Add 5 to each side.

3x-5+5=1+5

3x=6

Divide each side by 3.

Your answer would be x=2.

Answer: Their total budget last year was $40,000.

Step-by-step explanation:

Given : The Smiths spend 6% of their budget on entertainment.

i.e. , The money they spend on entertainment = 0.06 x ( Total budget)

{ 6% is converted to 0.06 , when we divide it by 100 to remove percentage)

Since , this year they plan to spend $2,580 on entertainment.

i.e. 0.06 x ( Total budget )  = $2,580

On dividing both sides by 0.06 , we get

( Total budget )  = $2,580 ÷ 0.06

=  $43,000

Thus , their total budget for this year = $43,000

Also, Their total budget this year is $3,000 more than last year.

Therefore , their last year total budget = ( Total budget this year ) - $3000

= $43,000 - $3000

= $40,000

Hence, their total budget last year was $40,000.

Answer:

64,125 I think

Step-by-step explanation:

7%x 5 years =35%

35% of 47, 500 is 16625

16625 + 47,500=64,125

Answer:

about $66,621

Step-by-step explanation:

Since its an increase in salary, we want 0.07+1 = 1.07 (if he was losing his salary, it instead would be 0.07-1, but that's not the case here)

Then we plug it in as 47,500(1.07)^x

he's expecting what would he get in his fifth year at the firm. So let's set x = 5.

47,500(1.07)^5 = $66,621.20721 or ≈ $66,621 to the nearest dollar.

Answer:

3+sqrt(13/2)

3-sqrt(13/2)

Step-by-step explanation:

2 (x-3) ^2 =13

Divide each side by 2

2/2 (x-3) ^2 =13/2

(x-3) ^2 =13/2

Take the square root of each side

sqrt((x-3) ^2) =±sqrt(13/2)

x-3 = ±sqrt(13/2)

Add 3 to each side

x-3+3 = 3±sqrt(13/2)

x = 3±sqrt(13/2)

Step-by-step explanation:

x=√3+3,−√1

Answer:

Area of blank is 326.56m²

Step-by-step explanation:

For a better and pictorial understanding of this problem please see attached for your reference.

Given data

Let the flower bed be the small circle with diameter d= 22m

Radius of small circle = 22/2=11m

Let the side walk be the big circle with diameter D= 4+4+22=30m

Radius of big circle =30/2 = 15m

We know that the area of circle

A1=πr²

Hence area of flower bed

A1=3.14*11²

A1= 379.94m²

Also area of side Walk

A2= πr²

A2= 3.14*15²

A2= 706.5m²

Area of blank

A3= area of side walk - area of flower bed

A3= A2-A1

A3= 706.5-379.94

A3= 326.56m²

Answer:151

Step-by-step explanation:

To write three equations whose solution is x=3.5, you can use different algebraic expressions. Three examples are x + 2 = 5.5, (2x - 5) / 3 = 1.8333, and x^2 - 12x + 42 = 0.

To write three equations whose solution is x=3.5, we can use different algebraic expressions to represent the same value. Here are three examples:

Answer:

-16x^2 +9

Step-by-step explanation:

To start this problem I would rearrange so that the terms with the x's come first. Making it look like this

(4x+3)(-4x+3)

Now you take the 4x and distribute it to the -4x and the 3.  

-16x^2+12x  This is the first part

Take the 3 and distribute it to the -4x and the 3 as well.

-12x+9

All you do now is combine the twoso you'd have

-16x^2 +12x -12x +9  Notice there are two terms that have a regular x with no exponent. This means you can combine them to simplify further.

-12x+12x=0  So you no longer have to include this term in your answer.

-16x^2+9 Would then be your final answer.

Answer:

length 42 cm and width 26 cm

Step-by-step explanation:

Given

Since Brian tied 136 foot rope around the perimeter , hence perimeter of house is 136 foot.

Given that shape of house is rectangular.

formula to calculate perimeter of rectangle can be used which is 2*(L+B)

where L is length of rectangle and B width of rectangle

Let the L and B be length of rectangular side of house

According to question

length of house is 10 feet less than twice the width of house

mathematically it can be represented as

L = 2*B - 10  --->eq. 1

Perimeter of house = 136 feet

using formula of Perimeter of rectangle

136 = 2*(L+B)

substituting the value of length in terms of width from eq. 1 in formula of perimeter

=> 136/2 = 2*B - 10 + B  (2*B+ B = 3B)

=> 68 = 3*B - 10

=> 78 = 3*B

B = 78/3 = 26

Therefore B which is width = 26 CM

length = 2*B - 10= 26*2 - 10 = 52-10=42

length of house = 42  cm

Hence dimension of Brian's house is length 42 cm and width 26 cm

Answer:

the total cost for the bench and the table minus the cost of the garden table which is $988 - 88 =900

Answer:

20 m.

Step-by-step explanation:

Formula for rhombus: base x height.

Base: 8

Height: 2.5

2.5 x 8 = 20.

Tip: Usually when finding the area of a rhombus there is another length (in this scenario, 4) to try to fool or trick you. It's the length of the slanted side to the right. A rhombus is a square or rectangle when you take the triangle and piece it into the slanted area, so even though it looks like a complicated parallelogram it really isn't.

Hope this helped ^^
