A local grocer cut his marketing budget by 38% last year. He spent only $650 on marketing this year and is happy with his decision. How much did the grocer spend on marketing last year?
Answer:
the amount the grocer spend on marketing last year = $ 1048.38
Step-by-step explanation:
To find the budget we will subtract the current marketing budget number from 100
As 38% = 0.38
i.e, 100 - 0.38= 0.62
Now divide the previous year budget amount percentage found by the amount spent this year
=650 / 0.62
= 1048.38
Final answer:
To find out how much the grocer spent on marketing last year, divide the current amount he spent by the remaining percentage of the original amount before the cut.
Explanation:
To find out how much the grocer spent on marketing last year, we need to determine the original amount before the 38% cut. Let's assume the original amount is x. If the grocer cut the marketing budget by 38%, it means he spent 100% - 38% = 62% of the original amount. The equation can be set up as: 0.62x = $650. To solve for x, divide both sides of the equation by 0.62. So, x = $650 ÷ 0.62 = $1048.39.

The figure ABCD is made up of two different triangles.ABD is a right-angled triangle.AB=25 cm,AD=60 cm,BD=65 cm and CE=45 cm.Find the area of figure ABCD.
the area of ABCD is 135
Answer:
2212.5 cm²
Step-by-step explanation:
ABCD is constructed from 2 right triangles ABD and BCD
The area (A ) of a triangle is calculated using the formula
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
In ΔABD, b = AD = 60 and h = AB = 25, hence
A = [tex]\frac{1}{2}[/tex] × 60 × 25 = 30 × 25 = 750 cm²
-----------------------------------------------------------------------------
In ΔBCD, b = BD = 65 and h = CE = 45, hence
A = [tex]\frac{1}{2}[/tex] × 65 × 45 = 1462.5 cm²
----------------------------------------------------------------------------
The area of figure ABCD = area of ΔABD + area of ΔBCD
A = 750 + 1462.5 = 2212.5 cm²
A contractor is building a fenced-in area at a daycare. The area will be rectangular with the length of its base equal to half the length of the height. The total area will be 5000 square feet. Determine the length of fencing the contractor will use
Answer:
The length of fencing will be [tex]300\ ft[/tex]
Step-by-step explanation:
Step 1
Find the dimensions of the rectangle
we know that
The area of a rectangle is equal to
[tex]A=bh[/tex]
In this problem we have
[tex]A=5,000\ ft^{2}[/tex]
so
[tex]5,000=bh[/tex] -----> equation A
[tex]b=\frac{h}{2}[/tex] -----> equation B
Substitute equation B in equation A
[tex]5,000=(\frac{h}{2})h[/tex]
[tex]10,000=h^{2}[/tex]
square root both sides
[tex]h=100\ ft[/tex]
Find the value of b
[tex]b=\frac{h}{2}[/tex] -----> [tex]b=\frac{100}{2}=50\ ft[/tex]
step 2
Find the length of fencing
The perimeter of a rectangle is equal to
[tex]P=2(b+h)[/tex]
we have
[tex]h=100\ ft[/tex]
[tex]b=50\ ft[/tex]
substitute
[tex]P=2(50+100)=300\ ft[/tex]

Answer:
Choose the best estimate for the capacity of a bath tub
A. 5 ml
B. 500 ml
C. 50 cl
D. 500 L
Step-by-step explanation:
The best estimate for the capacity of a bathtub is 500 Liters (500L) as it provides a measure that is comparably similar to the actual volume of a bathtub.
Explanation:The best estimate for the capacity of a bathtub would be 500 Liters (500L). This is because the capacity of a bathtub is usually much larger than a litre. Option A and B provide measurements in millilitres, which are much smaller units (a liter is 1,000 millilitres), and thus would not be sufficient to measure a bathtub's capacity. Option C is calling for centilitres, where 1 centilitre is equivalent to 10 millilitres, still way smaller than a bathtub's capacity. Hence, 500L (500 Litres) is the most reasonable estimation for the capacity of a bathtub.

To bake 5 cakes, you would need 12 1/2 cups of sugar by multiplying 2 1/2 cups, the amount needed for one cake, by the number of cakes.
Explanation:To calculate how many cups of sugar are needed to bake 5 cakes when a single cake recipe calls for 2 1/2 cups of sugar, you can simply multiply the amount of sugar needed for one cake by the number of cakes you plan to bake. Therefore, you have:
2 1/2 cups of sugar/cake × 5 cakes = 12 1/2 cups of sugar.
Here's the step-by-step calculation:
First, convert the mixed number to an improper fraction: 2 1/2 cups = 5/2 cups.Multiply the amount needed for one cake by the number of cakes: (5/2 cups) × 5 = 25/2 cups.Convert the improper fraction back to a mixed number: 25/2 cups = 12 1/2 cups.Therefore, you need 12 1/2 cups of sugar to bake 5 cakes.

54 square feet
67.5 square feet
81 square feet
85.5 square feet
Answer:
The answer is the third
The surface area of prism = 81 ft²
Step-by-step explanation:
∵ The triangular prism has 5 faces
- Two triangles ⇒ bases
- 3 rectangles ⇒ side faces
* to find the surface area of it, we will find the area of
each face and add them together
- Area of bases:
∵ The bases are right angle triangles with base 6 ft and height 4.5 ft
∵ Area triangle = 1/2 × base × height
∴ Area one base = 1/2 × 6 × 4.5 = 13.5 ft²
∴ Area two bases = 13.5 × 2 = 27 ft² ⇒ (1)
- Area of the first rectangle with dimensions 3 ft and 6 ft
∵ Area rectangle = L × W
∴ Area 1st rectangle = 3 × 6 = 18 ft² ⇒ (2)
- Area of the second rectangle with dimensions 3 ft and 7.5 ft
∴ Area 2nd rectangle = 3 × 7.5 = 22.5 ft² ⇒ (3)
- Area of the third rectangle with dimensions 3 ft and 4.5 ft
∴ Area 3rd rectangle = 3 × 4.5 = 13.5 ft² ⇒ (4)
Add (1) , (2) , (3) and (4)
∴ The surface area of prism = 27 + 18 + 22.5 + 13.5 = 81 ft²

sara gives tim x sweets
sara then eats 7 of her sweets
tim then eats half of his sweets
write an expression for the number of sweets sara and tim have now
I'm not sure, but I think this is the answer.
Answer:
Sara has 24-x-7
Tim has 24+x/2
Explanation:
So for Tim, He had 24 and received x no of sweets from Sara, so
24+x
After that, he ate half of it, so
24+x/2
Now for Sara, She had 24 and gave Tim x no of sweets, so
24-x
After that, she ate 7 of it, so
24-x-7
Hope it helps
The expression for the number of sweets Sara and Tim have now after sharing and eating some is represented as 29 - 0.5x.
Expression for the number of sweets Sara and Tim have now:
Sara gives Tim x sweets, so Sara has 24 - x sweets and Tim has 24 + x sweets.
After Sara eats 7 of her sweets, she has 24 - x - 7 = 17 - x sweets left.
Tim eats half of his sweets, so he has (24 + x) / 2 = 12 + 0.5x sweets left.
The total number of sweets Sara and Tim have now is: (17 - x) + (12 + 0.5x) = 29 - 0.5x.

Answer:
x < -3
Step-by-step explanation:
4x + 6 < - 6
Taking "6" from Left side of the equation to the right hand side, the sign "=6" changes to "-6", and we get,
4x < - 6 -6
Now, on right hand side, since both signs are same, therefore they add up to get,
4x < - 12
now, divide the complete equation by 4 we get,
4x/4 < -12/4
⇒ x < -3
Thus, the values that x can take are : -4,-5,-6,...-10....-20,....and so on
