Answer:
83
Step-by-step explanation:
40 - 15 = 25
25 - 7 = 18
40 + 25 + 18 =
83
We know that Albert has 40 toy cars.
If Brad has 15 fewer cars than Albert, Brad has 40 - 15 or 25 cars.
Now, we know that Chris has 7 fewer cars than Brad.
So Chris would have 18 cars.
Altogether, they would have 40 + 25 + 18 cars or 83 cars.
The quotient of 32 and 4 divided by the sum of 1 and 3
Answer:
2
Step-by-step explanation:
32 divided by 4 = 8 (quotient)
1 + 3 = 4 (sum)
8 divided by 4 = 2
Answer:
88
Step-by-step explanation:
22 is 40% of what number? A) 44 B) 55 C) 64 D) 88
Hey there! I'm happy to help!
When working with percents, the word "is" means "equals". We can use this to make an equation. The decimal form of 40% is 0.4. Our number will be represented by the variable n.
22=0.4n
Flip equation around so n is on the left (you don't have to do this, but I like having the variable on the left)
0.4n=22
We divide both sides by 0.4
n=55
Therefore, your answer is B) 55.
Have a wonderful day! :D
Answer:
55 =x
Step-by-step explanation:
Is means equals and of means multiply
22 = 40% * x
Change to decimal form
22 = .40x
Divide each side by .40
22/.40 = .40x/.40
55 =x
Choose the correct description of the graph of the compound inequality 3x + 1 > 10 and 4x less than or equal to 20 (1 point) A number line with an open circle on 3, a closed circle on 5, and shading in between A number line with an open circle on 3, shading to the left, and a closed circle on 5, shading to the right A number line with a closed circle on 3, shading to the left, and an open circle on 5, and shading to the right A number line with a closed circle on 3, an open circle on 5, and shading in between
Answer:
A number line with an open circle on 3, a closed circle on 5, and shading in between
Step-by-step explanation:
The solution to the first inequality is ...
3x +1 > 10
3x > 9 . . . . . subtract 1
x > 3 . . . . . . divide by 3
__
The solution to the second inequality is ...
4x ≤ 20
x ≤ 5 . . . . . divide by 4
__
The solution set is then ...
3 < x ≤ 5
This is represented by a graph with an open circle at 3, a closed circle at 5, and shading between.

Tom bought 20 boxes of flowers. Each box cost him £6. Each box contains 15 flowers. 3/5 He sells of the total number of flowers for 70p each. He then sells the remaining at 50p each. Work out the total profit Tom makes.
330
20 * 6 equals 120 that is the cost price
and 3/5 of the 15 flowers is 9 which was sold for 7
and the remaining that is 15 - 9 that's 6 sold for 50 each
now times it by 70 * 9 equals 630 50 * 6 equals 300 so 630 - 300 equals to 330 that is the profit
I hope this helps
Answer:
66
Step-by-step explanation:
The money he spent:
20 x 6 = 120
=> The number of flowers he bought:
=> 15 x 20 = 300
3/5 of 300 = 900/5 = 180
So, he sold 180 flowers for 70cents.
=> 180 x 70 = 12600 cents
=> 126 dollars
The remaining for 50 cents
=> 2/5 x 300 = 600 / 5 = 120
So, he sold 120 flowers for 50 cents
=> 120 x 50 = 6000 cents
=> 60 dollars
He got a total of 60 + 126 = 186 dollars.
He spent 120 dollars in the starting to buy the flowers.
=> 186 - 120
=> 66 dollars
So, he gets a profit of 66 dollars.

Find the area of the figure in the image attached. Round to the nearest tenth if necessary.
Answer:
The area of the figure shown is 37.5cm^2, or 37 1/2cm^2, depending on what it wants from you.
Step-by-step explanation:
Break the shape into a triangle with measurements of 2.5, and 6.
And then the Rectangle with measurements of 6, and 5.
area of a rectangle is w*l so 6*5=30in
Area of a triangle is b*h*1/2 or b*h divided by 2 (either way both are the same, chose what makes you comfortable, I will use the first one.),
2.5*6*1/2
2.5*6=15
15*1/2=7 1/2cm or as a decimal 7.5cm
Now add the two for the full area, 30+7.5=37.5cm

PLEASE HELP ME SOLVE THESE!
-3n-4n-17=25
-15+7.5(2d-1)=7.5
Please show me how as well please :)
Answer:
-3n-4n = 25 + 17
-7n = 42
n= -6
the main thing for here is to combine the like terms and to solve for n which is done by putting all the numbers with variables on one side and the non variables on the other and divide each side by the number that has the variable. Remember that when you bring numbers on the other side, you change its sign, for example if you have 5 on one side and you bring to the other side of the equal sign it becomes -5.
-15 + 15d -7.5d =7.5
15d - 7.5d = 7.5 + 15
7.5d = 22.5
d = 3
for the part where theres 7.5(2d-1)
you multiply each number inside the bracket by 7.5, its called distributivity of multiplication
hope that answers your question
hope you understand what i wrote lol
good luck:)
Answer:
Question 1
Original Equation:
-3n-4n-17=25
Add 17 to both sides (cancels out the -17)
-3n-4n=42
Combine -3n and -4n.
-7n=42
Divide by -7
n = -6
Question 2
Original Equation:
-15+7.5(2d-1)=7.5
Distribute:
-15+15d-7.5=7.5
Add 7.5 to both sides:
-15+15d=15
Add 15 to both sides:
15d=30
Divide by 15:
d = 2

which construction can you use to prove that the Pythagorean theorem based on similarity of triangles
The construction that you can use to prove the Pythagorean Theorem based on similarity of triangles is 2nd construction. Please see the attached file.
What are similar triangles?Two triangles are similar triangles of their corresponding angles are equal corresponding sides are in equal ratios.
The Pythagorean theorem, also known as Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It mentions that the sum of the squares of the other two sides is equal to the square of the hypotenuse (the side opposite the right angle).

Answer:
B) 30
Step-by-step explanation:
Since ABCD is a parallelogram the diagonals bisect each others in their midpoint.
Wich means that BE = ED
● BE = ED
● (2/3)x = x-10
Substract x from both sides
● (2/3)x -x = x-10 - x
● (2/3) x - x = -10
Multiply x by 3 then ubstracr it from 2x
● (2x-3x)/3 = -10
● -x/3 = -10
Multiply both sides by -3
● (-x/3)×(-3) = -10 ×(-3)
● x = 30

Arc RQ = 180°
Step-by-step explanation:
PEQ is an inscribed angle and the measure of an inscribed angle in a circle is equal to half of the arc it sees.
The perimeter of a circle is always 360° therefore
2 × (5x + 15) + 9x + 17 + 6x - 12 = 25x + 35 = 360°
25x = 360 - 35
25x = 325
x = 13
Since arc RQ is equal to 10x + 30 we replace x with the value we just got
10×13 + 30 = 160°

Answer:
504 in³
Step-by-step explanation:
The volume of the overall outside dimensions is their product:
Voverall = (12 in)(8 in)(6 in) = 576 in³
The volume of the "slot" is the product of its dimensions:
Vslot = (6 in)(6 in)(2 in) = 72 in³
Then the volume of the figure shown is ...
Vfigure = Voverall -Vslot = 576 in³ -72 in³ = 504 in³
Answer:
504 inches cubed
Step-by-step explanation:
The area missing is 6*6*2=72
The whole area is 576
subtract the two and get 504
since we are talk about volume it is 50 inches cubed
