what is the Area of the parallelogram
Answer:
55
Step-by-step explanation:
The Distance between (-2, -5) and (-2, 6) is 11 and the distance between (-2, 5) and (3, 5) [the altitiude] is 5. 11 x 5 is 55 so therefore the area is 55 :)
a laptop computer is purchased for $1800. after each year the resale value decreases by 35%. what will the resale value be after 5 years? round to nearest dollar.
Answer:
1800-35%=1170
1170-35%=760,5
760,5-35%=494,325
494,325-35%=321,31
311,31-35%=208,85
after round it is 209
Answer:
$209
Step-by-step explanation:
1800-(1800*.35)=1170
1170-(1170*.35)=760.5
760.5-(760.5*.35)=494.325
494.325-(494.325*.35)=321.31125
321.31125-(321.31125*.35)=208.8523125

1 yd² of soil containing 30% clay was mixed into 2 yd of soil containing 45% clay. What is the clay content of the mixture?
Answer:
105% ?
Step-by-step explanation:
I'm not entirely sure if the 1 yard 'squared' is considered in the 30% but assuming it's not ... 1yd =30% 1yd^2=60% and 2yd=45% so 60%+45%=100%

" ≥ " sign represents at least or more than.
" ≤ "sign represents at least or less than.
Answer:
B
Step-by-step explanation:
The sign < means less than
Given x is the volume of the pool
Therefore, x < 38 means the volume of the pool is less than 38 m³
For information, the statements written as inequalities would be
A: x > 38
B: x < 38
C: x ≥ 38

what should be subtracted from
[tex] {a}^{2} - 7ab \: + {3b}^{2} [/tex]
to get
[tex]( - 4 {a}^{2} + 6ab \: + 3 {b}^{2} )[/tex]
?
-5a²+13ab should be subtracted.
Step-by-step explanation:-Based on the given conditions, formulate,
[tex]→- {a}^{2} - 4 {a}^{2} + 13ab[/tex]
[tex]→-({a}^{2} - 4 {a}^{2}) + 13ab[/tex]
Taking the coefficients or numbers, we get,
[tex]→(- 1 - 4) {a}^{2} + 13ab[/tex]
[tex]→ - 5 {a}^{2} + 13ab[/tex]
Given :
What should be subtracted from a² – 7ab + 3b² to get – 4a² + 6ab + 3b² ?
Solution :
Let the required expression to be subtracted be x
⇢ a² – 7ab + 3b² – x = – 4a² + 6ab + 3b²
⇢ a² – 7ab + 3b² – (– 4a² + 6ab + 3b²) = x
⇢ a² – 7ab + 3b² + 4a² – 6ab – 3b² = x
Combining the like terms :
⇢ a² + 4a² – 7ab – 6ab + 3b² – 3b² = x
⇢ 5a² – 13ab = x
⇢ x = 5a² – 13ab
Therefore,
5a² – 13ab should be subtracted from a² – 7ab + 3b² to get – 4a² + 6ab + 3b².
x^2(x+2)(x+6)=0
What are the solutions to the equation?
Answer:
3 solutions
Step-by-step explanation:
x = 0; x = 2; x = -6
As we are given with an equation as follows :
[tex]{:\implies \quad \sf x^{2}(x+2)(x+6)=0}[/tex]
As product of these three factors is equal . So , any of these factor can be 0 as product is 0 only when one of the expressions which are multiplied is 0. So , 3 cases arises as follows ;
Case I :-[tex]{:\implies \quad \sf x^{2}=0}[/tex]
On raising ½ power to both sides we have ;
[tex]{:\implies \quad \sf x=\pm \: 0}[/tex]
Now , as +0 and -0 have no difference in them . So , it's simply 0
[tex]{:\implies \quad \sf So\quad x=0}[/tex]
Case II :-[tex]{:\implies \quad \sf x+2=0}[/tex]
[tex]{:\implies \quad \sf So\quad x=-2}[/tex]
Case III :-[tex]{:\implies \quad \sf x+6=0}[/tex]
[tex]{:\implies \quad \sf So\quad x=-6}[/tex]
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{Hence \:\: x\in \{0,\: -6,\: -2\}}}}[/tex]
Dave buys a coat for £20, a hat for £15 and a pair of gloves for £5.
Later, he sells the coat at 50% profit. He sells the hat for £18 but has to sell the gloves at a 20% loss.
What is his overall percentage profit?
Answer:
30%
Step-by-step explanation:
Purchases:
Coat £20
Hat £15
Gloves for £5
Total amount of purchases: £20 + £15 + £5 = £40
Sales:
Coat at 50% profit: 150% × £20 = 1.5 × £20 = £30
Hat: £18
Gloves at a 20% loss: 80% of £5 = £4
Total amount of sales: £30 + £18 + £4 = £52
Amount of profit: £52 - £40 = £12
Percent of profit: £12 / £40 × 100% = 30%
(PLEASE HELP!) (IM GIVING GOOD POINTS!) Michaela buys 2 cartons of eggs at $1.58 a carton, 415 pounds of ground turkey at $6.99 a pound, and a jar of strawberry jam for $4.38. She gives the cashier four $10 bills.
How much change will Michaela receive?
Enter your answer as a decimal rounded to the nearest hundredths place, if necessary, like this: 4.25
Answer:
Michaela gets 3.45$ back.
Step-by-step explanation:
1 carton of eggs = 1.58$
she buys 2, so 2 times 1.58= 3.16$
1 pound of turkey = 6.99$
she buys 4.15 pounds, so 4.15 times 6.99= 29.01$
she buys a jar of jam for 4.38$
4.38 + 3.16 + 29.01 = 36.55$
4 times 10= 40
40 - 36.55 = 3.45$
Answer:
$3.10
Step-by-step explanation:
The cost of the goods Michaela buys is ...
2 cartons eggs at $1.58 per carton = $3.16
4 1/5 pounds turkey at $6.99 per pound = $29.36
1 jar of jam at $4.38 per jar = $4.38
The total is then ...
$3.16 +29.36 +4.38 = $36.90
Four $10 bills will be $40, so the change is ...
$40 -36.90 = $3.10
Michaela will receive $3.10 in change.
_____
Additional comment
We know that Brainly often mangles mixed numbers, so we have assumed that "415" is intended to be 4 1/5. If it is intended to be 4.15 pounds, then the price of the turkey, and the change, will be different by about $0.35. Michaela's change will increase by that amount.

a + c = 30
12a + 8c = 280
Answer:
a=10 and c=20
Step-by-step explanation:
This is a system of equations. I will solve using the substitution method.
a+c=30
12a+8c=280
Solving for a:
a+c-c=30-c
a=30-c
Substituting a into the second equation:
12(30-c)+8c=280
360-12c+8c=280
360-4c=280
-4c=-80
c=20
Substituting into the original equation:
a+20=30
a+20-20=30-20
a=10
To prove this answer is correct, I will plug the solutions back in to the original equation.
a+c=30
10+20=30
30=30, True
12a+8c=280
12*10+8*20=280
120+160=280
280=280, True
Therefore, a=10 and c=20.

Radically reduce square root of 243
Answer: 9sqrt(3)
Step-by-step explanation:
First, we can prime factorize 243.
243 = 3^5
Therefore we are computing the square root of 3^5
3^5 = 3^4 * 3^1; 3^4 = (3^2)^2
Therefore, sqrt(3^5) = sqrt((3^2)^2))*3^1)
= 3^2*sqrt(3)
= 9sqrt(3)

Using this formula
I= (P+r×t)
Where:
I=Interest=?

t=Time=5 years
Hence:
I= ($400×0.035 x 5)
I= $70

The band director at a high school wants to know what percentage of parents supports a decrease in the budget for fine arts. Because many parents attend the school’s annual musical, the director surveys the first 30 parents who arrive at the show. Explain why this sampling method is biased. Is the proportion of parents in the sample who support the decrease likely greater than or less than the proportion of all parents in the school who support the decrease?
Using sampling concepts, it is found that the sampled is biased because only parents who attend the school's musical show are surveyed, hence they are not very likely to support the decrease, and the population proportion should be greater than the one found in the show.
How are samples classified?Samples may be classified as:
Convenient: Drawn from a conveniently available pool.Random: All the options into a hat and drawn some of them.Systematic: Every kth element is taken. Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.Stratified: Also divides the population into groups. Then, a equal proportion of each group is surveyed.A sample has to take into account all aspects of the population, otherwise it is biased. In this problem, either people support the decrease, or they do not. Only people that went to the show were surveyed, that is, people who are unlikely to support the decrease, which generates bias, as the population proportion should be greater than the one found in the show.
