Answer: The dimensions of the rectangle are 7 cm × 4 cm
Step-by-step explanation:
let,
Breadth of the rectangle (l) = x
Length of the rectangle (b) = x + 3
Area of the rectangle = 28 cm²
Area of the rectangle = l × b
⇒ (x) × (x + 3) = 28
⇒ x² + 3 x = 28
⇒ x² - 3 x - 28 = 0
⇒ x² - 7 x + 4 x - 28 = 0
⇒ (x - 7) + 4(x - 7) = 0
⇒ (x - 7)(x + 4) = 0
⇒ x = 4
Breadth = 4 cm
Length -
⇒ 4 + 3
⇒ 7 cm

Answer:
x = 40
Step-by-step explanation:
∠D = ∠ADB + ∠BDC
= 30 + 40
= 70°
In ΔBDC,
BD = CD
∠DBC = ∠DCB {angles opposite to equal sides are equal}
∠DBC + ∠DCB + ∠BDC = 180 {Angle sum property}
2∠DCB + 40 = 180
2∠DCB = 180 -40
2∠DCB = 140
∠DCB= 140/2
∠DCB = 70°
In ΔADC,
x + ∠D + ∠C = 180
x + 70 + 70 = 180
x + 140 = 180
x = 180 - 140
x = 40°
In 2019, the New England Patriots played 16 football games. The ratio of the number of games they won to the the number of games they lost was 3/1. How many games did they win? How many games did they lose?
Answer:
New England quarterback Tom Brady has the Patriots rolling again. ... In Week 2, they shut out the hapless Miami Dolphins, 43-0. ... Their start to 2019 has been so strong, even against opponents with a combined record ... and regress their win-loss records to account for the small number of games played.
Step-by-step explanation:
The number of games they won is 12 and the number of games they lost is 4 based on the given ratio.
What are the ratio and proportion?
The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Suppose the number of games they won is W and the number of games they lost is L.
As per the given
Total games L + W = 16
Ratio W/L = 3/1
W = 3L
L + 3L = 16
4L = 16
L = 4
And, W = 3 x 4 = 12
Hence"The number of games they won is 12 and the number of games they lost is 4 based on the given ratio".

Family spends $240 per week on food. If this is %16 of their income, what is the family's weekly income?
Answer: The family's weekly income is $1500
-------------------------------------------
Work Shown:
x = weekly income (in dollars)
16% of x = amount spent on food per week
16% of x = 240
(16/100)*x = 240
0.16*x = 240
0.16*x/0.16 = 240/0.16
x = 1500
Pls Mark as brainliest
Answer:
1500
Step-by-step explanation:
16% of x = amount spent on food per week
16% of x = 240
(16/100)*x = 240
0.16*x = 240
0.16*x/0.16 = 240/0.16
x = 1500

-1 2/3 divided by (-2 1/5)
Answer:0.75757575757
Answer:
Fraction Form
25/33
Decimal Form
0.75
Step-by-step explanation:
First, convert the mixed fraction into an improper fraction, so it would look like:
-5/3 / (-11/5)
Next, divide. Remember, when multiplying fractions all you do is flip the one in parantheses and make both of them positive, so it would look like:
5/3 x 5/11
Finally, multiply so you do the two top numbers which is 5 x 5= 25 and the two bottom numbers so 11 x 3 is 33. Then your final answer is 25/33
Brandon made 80 cups of lemonade for his party. At the party, 10 cups of lemonade are finished eac hour. How many hours will Brandon's lemonade last?
Answer:
8 hours
Step-by-step explanation:
let number of hours it takes to finish the cup be t,
we know that we have 80 cups, and we know we can finish 10 cups per hour so,
10t = 80 which is 10 times t = 80
Solve for t,
10t/10 = 80/10
t = 8
Jake bought 3 drawing pens for $8.07. Each pen costs the same amount. About how much did he spend for one pen? * 2 points
Given:
Jake bought 3 drawing pens for $8.07.
Each pen costs the same amount.
To find:
How much did he spend for one pen?
Solution:
Let x be the cost of each pen. Then
Cost of three pens = 3x
Jake bought 3 drawing pens for $8.07.
[tex]3x=8.07[/tex]
Divide both sides by 3.
[tex]x=\dfrac{8.07}{3}[/tex]
[tex]x=2.69[/tex]
Therefore, he spend $2.69 for one pen.

Answer:
golden corral equation y=1.5x+15
western sizzlin equation y=2.5x+13
yes they are linear because if you were to graph them they would have a straight line and they would go upwards because the slope is positive
For which one you would pick would depend on how much you drink. If you drink a lot you should probably go to golden corral but if you dont drink that much then western sizzlin is probably the best choice.

Susie's dog is 2feet tall. When she measures her dog in inches he was 24 inches. Why is there an increase in inches
Given:
Susie's dog is 2 feet tall. When she measures her dog in inches he was 24 inches.
To find:
Why is there an increase in inches.
Solution:
It is given that Susie's dog is 2 feet tall.
We know that,
1 feet = 12 inches
Using this conversion, we get
2 feet = 2×12 inches
2 feet = 24 inches
So, the measures 2 feet and 24 inches are equal.
Therefore, if Susie's dog is 2 feet tall then he is 24 inches tall because both of these measure are equal.
Reshawn is buying 3 books in a trilogy set for $24.81. He will save $6.69 by buying the trilogy set instead of buying individual books. If each book costs the same amount, how much does each of the 3 books cost when purchased individually? Show your work.
$10.50
Explanation:
Let x be the cost of the individual books. Then 24.81=3x−6.69
3x= 24.81+ 6.69 =31.50
x=31.50/3=10.50
