Answer: 5.22kg
Step-by-step explanation:
From the question, a farmer sells 8.7 kilograms of pears and apples at the market. Of the pears and apples sold, 2/5 of this weight is pears, and the rest is apples. To calculate the kilograms of apple sold goes thus:
Total kilograms sold = 8.7kg
Fraction of pears weight = 2/5
Pears kilograms sold = 2/5 × 8.7
= 0.4 × 8.7
= 3.48kg
Since the kilograms of pears sold is , 3.48kg, to get the kilograms of apple sold, we subtract 3.48kg from 8.7kg. This will be:
= 8.7kg - 3.48kg
= 5.22kg

<B=39.80
Step-by-step explanation:
tan(b)=5/6
b=[tex]tan^{-1}[/tex](5/6)
b=39.80557109
b=39.80 to the nearest hundredth.
Answer:
[tex] \angle B= 39.81\degree[/tex]
Step-by-step explanation:
[tex] \because \tan \angle B = \frac {AC}{BC} \\\\
\therefore \tan \angle B = \frac {5}{6} \\\\
\therefore \tan \angle B = 0.833333333\\
\therefore\angle B= \tan^{-1}(0.833333333)\\
\therefore\angle B= 39.805569965\degree \\

Step-by-step explanation:
6 times a number is 27 less than the square of that number. Find the
positive solution.
Answer:
x = 9
Step-by-step explanation:
To solve these problems, you first set up an equation representing the information given.
6x = x² - 27
This turns into a quadratic equation which you need to factor out.
0 = x² - 6x - 27
You want to choose two numbers that multiply to -27, and add up to -6
0 = (x - 9)(x + 3)
If you're unfamiliar with factoring, you take the opposite sign of the number in the parentheses because it's a shortcut when setting it equal to 0.
x = 9, -3
Since it asks for the positive solution only, the answer is x = 9.
I hope this helps!

b. 2 + 4 + 2 +1-10
C. 4 - 10 +2 +2 +1
d. 10-2-4-2 - 1
Answer:
D.
Step-by-step explanation:
10 - 2 - 4 - 2 - 1 since he went to dump all those so you have to subtract them from the original amount.

Step-by-step explanation: Put in (-7) in place of x, and (7) in place of y in the equation If the equation does not equal -2, it is not a solution. If it does equal -2, it is a solution.
(-7,7)
6x+9y=-2
Plug in -7 for x and 7 for y.
6(-7)+9(7)=-2?
Solve the equation.
-42+63= -21
So, (-7,7) is not a solution to this equation.

Preston signed up for overdraft protection at his bank. This bank charges an overdraft fee of $30 for insuffcient funds. Preston has a balance of $50. He then purchased a pair of tennis shoes using his bank debit card. If the total charge for the tennis shoes is $52, what will be Presont's new balance?
Answer:
-$32
Step-by-step explanation:
Given that
Overdraft fee = $30
Preston Balance = $50
Total expenditure = $52
As per the given question the solution of new balance is provided below:-
To reach the new balance of Presont's first we need to find out the overdraft balance which is as follows:-
Overdraft balance = Balance - Total expenditure
= $50 - $52
= -$2
Since there is a balance of $50 but Pretson purchased for $52 value that results -$2 overdraft balance. In order to determine the new balance we simply added the overdraft fee and overdraft balance which is shown in negative sign.
Now according to the question the New balance of Presont's = Overdraft balance - overdraft fee
= -$2 - $30
= -$32

What is the area of the figure below? Use 3.14 for pi. Round your answer to the nearest hundredth.
Answer:
area of the figure ≈61.23 cm² to the nearest hundredth
Step-by-step explanation:
To find the area of the figure, we will follow the steps below;
Looking at the figure, we will see that the figure comprises of both semi-circle and a parallelogram
area of figure = area of semicircle + area of parallelogram
first, we will find the area of the semi-circle
area of a semi-circle = πr² /2
from the diagram given, diameter = 7cm
but diameter = 2r, this implies that radius r = d/2, hence radius r = 7/2 = 3.5 cm
π = 3.14
Lets insert the values into the formula
area of a semi-circle = πr² /2
=3.14×3.5² /2
=3.14×12.25 /2
=19.2325 cm²
Area of a parallelogram = b×h
where b = base and h = height
from the figure given, base b = 7cm and height h = 6 cm
Lets insert the values into the formula
Area of a parallelogram = b×h
= 7×6
=42 cm²
area of the figure = area of semicircle + area of parallelogram
=19.2325 cm² + 42 cm²
=61.2325 cm²
≈61.23 cm² to the nearest hundredth
area of the figure ≈61.23 cm² to the nearest hundredth

a) How many blue flowers are there?
6
b) Write down the mode.
(ive answered A anyone know b?)
Answer:
MODE is the number which appears most often in a set of numbers. Here no number is repeated. So, there is no MODE
｡☆✼★ ━━━━━━━━━━━━━━ ☾
As the other user stated, the mode is the value that appears the most
Simply look for which colour has the most number of flowers
Thus, the mode would be "yellow"

Equation with angle addition can someone please answer I need help please
Answer:
99°
Step-by-step explanation:
We know that angles on a straight line add up to 180° so we can set up an equation to find the value of x.
In an equation it's important to do the operation you want to on both sides because if you do an operation on one side only you will end up changing the whole equation and that will make the value of x wrong so its an important rule to remember.
8x - 13 + 7x - 17 = 180
→ Simplify
15x - 30 = 180
→ Add 30 to both sides to isolate 15x
15x = 210
→ Divide both sides by 15 to isolate x
x = 14
But we are not finished, the specifies us to find ∠MON and we have only found the value of x so we have to substitute x back into 8x - 13 to find the value of ∠MON
8x - 13
→ Substitute x = 14 back into into the expression
8 × 14 - 13
→ Simplify
112 - 13 = 99
So the value of ∠MON is 99°
The Zearn Fair charges $1.75 for entrance and $1.05 for each ride. Mr. Sawicki brings $20 with him to the fair. What is the greatest number of rides Mr. Sawicki can go on if he uses $2.50 for food? How much money can Mr. Sawicki spend in total
Step-by-step explanation:
So
Total money = 20
Entrance fee = 1.75
Food = 2.50
Ride = 1.05
Amount spend = 1.75 + 2.05 = 3.8
Left for rides = 20 - 3.8 = 16.2
So rides = 16.2 ÷ 1.05 = 15
I think atleast 15 rides

Sandra saves 9% of her salary for retirement this year salary was 1000 more than in her previous year and she saved $4050 what was your salary in the previous year
Answer:
$44,000
Step-by-step explanation:
The statement indicates that Sandra saves 9% of her salary and she saved $4,050 this year. That means that the 9% of her salary, x, is equal to $4,050. You can write the following:
x*0.09= 4,050
Now, you can isolate x to find her salary this year:
x=4,050/0.09= 45,000
Then, you have that this year salary was 1000 more than in her previous year. As you have found her salary for this year, you can subtract 1,000 from it to find her salary in the previous year:
45,000-1,000= 44,000
According to this, the answer is that her salary in the previous year was $44,000.

Help please!!!!! I hate this part of volume of pyramids :/
Answer:
h = 6 cm
Step-by-step explanation:
The volume (V) of a pyramid is calculated as
V = [tex]\frac{1}{3}[/tex] Ah ( A is the area of base and h the height )
Here A = 3 × 2 = 6 cm² and V = 12 , thus
[tex]\frac{1}{3}[/tex] × 6 × h = 12, that is
2h = 12 ( divide both sides by 2 )
h = 6 cm
