A diagonal of a television screen measure 30 inches. The screen is 18 inches tall,as shown. which expression is equal to the length of the television screen in ,inches
Answers
Answer:
24 inches
Step-by-step explanation:
The television is a rectangular screen, the diagonal represents the hypotenuse side while the length and height are the adjacent and opposite side in no particular order hence we can use Pythagoras theorem to find the length.
Recall that the theorem states that
opposite side^2 + adjacent side^2 = hypotenuse side^2
let the length of the television screen be L
L^2 + 18^2 = 30^2
L^2 + 324 = 900
L^2 = 900 - 324
L^2 = 576
L = √576
= 24 inches

Step-by-step explanation:
When graphing a parabola in the format [tex]y = a(x-h)^2+k[/tex], know that:
if a is positive, the parabola points upwards (meaning that there is only a minimum value, no maximum exists) if a is negative, the parabola points downwards (there is a maximum, but no minimum)You can try playing around with these values on a graphing calculator like Desmos!
In both cases, k would be the minimum or maximum value.
For this problem, k = 25. So, the maximum is 25 ft.

Rizzo has $1.50 less in his piggy bank than his sister Shonda. If Shonda had $9 more, she would have three times as much money as Rizzo. How much money do each of the children have in their banks?
Answers
Answer:
Shonda has ( x )dollars in her piggy bank.
Rizzo has ( x-1.50 )
if Shonda has $9 more than x; (x+9),would be equal to
3 times the dollars Rizzo has, or, 3(x-1.50). The two quantities are equal, we can solve for x.
x+9 = 3(x-1.50)
Dustribute the 3
x+9 = 3x - 4.50
Isolate the variable on the left and constants on the right of the equation by subtracting 3x and 9 from both sides.
x+9 = 3x - 4.50
-3x-9 = -3x - 9
-2x = - 13.50
Divide both sides by - 2
Shonda has; x = 6.75
Rizzo has; (6.75 - 1.50) = 5.25
6.75 + 9 = 3(6.75 - 1.50)
15.75 = 3(5.25) or 15.75.
Passes the check.
Shonda has $6.75 in her piggy bank and Rizzo has $5.25.
25. The width of a rectangle is (x+1) and the length is (X-6). What is the length and width of the rectangle if the area is
30 square feet?
Answers
Answer:
x=−4 or x=9
Step-by-step explanation:
1- As we know the formula for Area of rectangle = length x width
2- Multiply given width = (x+1) with length = (x-6)
3-Equation will be (x+1)(x-6) = 30
4- Solving x^2−5 x−6 = 30
5- x^2−5 x -36 = 0
6-Factor left side of equation.
(x+4)(x−9)=0
Set factors equal to 0.
x+4=0 or x−9=0

Find three consecutive even integers such that the sum of the squares of the first two is four less than twice the square of the third.
Answers
Answer:
the three consecutive even integers are -2, 0, 2
Step-by-step explanation:
Let the first even integer = n
Let the second even integer = n + 2
Let the third even integer = n + 4
From the given statement, we form the equation below
(n²) + (n + 2)² + 4 = 2(n + 4)²
Expand this equation;
n² + (n + 2)(n + 2) + 4 = 2(n + 4)(n + 4)
n² + n² + 2n + 2n + 4 + 4 = 2(n² + 4n + 4n + 16)
2n² + 4n + 8 = 2(n² + 8n + 16)
2n² + 4n + 8 = 2n² + 16n + 32
collect like terms together;
2n² - 2n² + 4n - 16n = 32 - 8
- 12n = 24
-n = 24/12
-n = 2
n = -2
Second integer = n + 2
= -2 + 2 = 0
Third integer = n + 4
= -2 + 4
= 2
Therefore, the three consecutive even integers are -2, 0, 2
The three consecutive even integers are -2, 0, 2
The calculation is as follows:
Let us assume the first even integer = n
Let us assume the second even integer = n + 2
Let us assume the third even integer = n + 4
Now
[tex](n^2) + (n + 2)^2 + 4 = 2(n + 4)^2\\\\n^2 + (n + 2)(n + 2) + 4 = 2(n + 4)(n + 4)\\\\n^2 + n^2 + 2n + 2n + 4 + 4 = 2(n^2 + 4n + 4n + 16)\\\\2n^2 + 4n + 8 = 2(n^2 + 8n + 16)\\\\2n^2 + 4n + 8 = 2n^2 + 16n + 32\\\\2n^2 - 2n^2 + 4n - 16n = 32 - 8\\\\- 12n = 24[/tex]
n = -2
Now
Second integer = n + 2
= -2 + 2 = 0
And,
Third integer = n + 4
= -2 + 4
= 2

A recipe requires 1/4 of a cup of cranberries for 1 batch of scones how many batches of scones can be made using 6 1/2
Answers
Answer:
26
Step-by-step explanation:
6 times 4 =24 then 4/1 times 1/2 = 4/2 equals 2 and then you add 2 to 24 and that is 26.
Answer:
26
Step-by-step explanation:
If 1/4 of a cup of cranberries and make 1 batch, and there are four 1/4 cups in a whole cup, then 1 cup of cranberries can make 4 batches of scones.
By that same logic, there are two 1/4 cups in 1/2 a cup, so 1/2 cup of cranberries can make 2 batches of scones.
So, with the knowledge that 1 cup of cranberries makes 4 batches of scones, 6 cups of cranberries can make 6 x 4 = 24 batches, and adding on 1/2 cup gives us 2 more batches for a total of 24 + 2 = 26 batches.

Answer the question below* 1 point A grocery store offers a service where customers can place an order and have their groceries delivered to their home for an additional fee. The equation y = 1.1x can be used to find y, the total cost in dollars for x, the grocery cost in dollars. Arlyn has groceries delivered for a total cost of $119.90. He says his grocery cost must be $108.90. Is Arlyn correct? Explain your reasoning. Yes O No
Answers
Answer:
No.
Step-by-step explanation:
For starters, it says the representation of the grocery cost is x, but we have the equation y=1.1x. So, because 1x+0.1x=1.1x, we can infer that 0.1x is equal to our delivery cost, which we can call z.
Now we have two equations. y=x+z, and z=0.1x.
For this problem, we don't necessarily have to find the actual cost: just prove whether or not Arlyn is correct or incorrect by plugging in numbers for variables. So we can plug in our values of 119.90 (total value) and 108.90 (supposed grocery cost value) into our equations.
We now have 119.90=108.90+z, and z=0.1(108.90). First we can compute z=0.1(108.90). Since we know multiplying by 0.1 is the same as multiplying by 1/10, it's easy to get 108.90/10, which is 10.89. Now we can substitute 10.89 into our second equation for z, to get 119.90=108.90+10.89, where you get 119.90=119.79, which is not true. Therefore, Arlyn is incorrect, because $119.79 is not equal to $119.90.
