Answers
Answer:
x² + 8x + 16
Step-by-step explanation:
(x + 4)²
= (x + 4)(x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 4) + 4(x + 4) ← distribute parenthesis
= x² + 4x + 4x + 16 ← collect like terms

you got a bunch of apples. one third is rotten, one fourth is ripe. How much is left?
Answers
Answer:5/12
Step-by-step explanation:
1/3=4/12
1/4=3/12
=7/12
12/12-7/12=5/12
One third of 12 =1/3 *12/1
= 4
Therefore 4 apples are rotten
One fourth of 12 = 1/4 *12/1
= 3
Therefore 3 apples are ripe
Number of apples left =. 12- 3 +4
According to the DMAS rule we have to do Addition first ,so 3+4 = 7
Now we have to subtract 12-7 that will be 5
so therefore number of apples left = 5

Answers
Answer:
The actual length of the room is 40 feet
Step-by-step explanation:
Given
[tex]Scale = \frac{1}{2}\ inch : 12\ feet[/tex]
Required
Determine the actual measurement of [tex]3\frac{1}{3}\ inches[/tex]
Represent the required actual measurement with x
i.e.
[tex]3\frac{1}{3}\ inches : x[/tex]
And we have:
[tex]\frac{1}{2}\ inch : 12\ feet[/tex]
[tex]3\frac{1}{3}\ inches : x[/tex]
Cross Multiply
[tex]x * \frac{1}{2} = 12 * 3\frac{1}{3}[/tex]
Convert fraction to improper fraction
[tex]x * \frac{1}{2} = 12 *\frac{10}{3}[/tex]
[tex]\frac{x}{2} = \frac{120}{3}[/tex]
[tex]\frac{x}{2} = 40[/tex]
Multiply both sides by 2

A triangular pane of glass has a height of 48 inches and an area of 576 square inches. What is the length of the base of the pane?
URGENT
Answers
Answer:
12
Step-by-step explanation:
Solution:
We know that:
Area of triangular pane = 576 in²Height of triangular pane = 48 inArea of triangle formula = 1/2 x Base x AltitudeSubstituting the height and the area of the pane in the formula
Area of triangle = 1/2 x Base x Altitude = 576 in²1/2 x Base x 48 = 576 in²Simplifying the LHS:
1/2 x Base x 48 = 576 in²Base x 24 = 576 in²Dividing 24 both sides
(Base x 24)/24 = 576/24Base = 576/24 = 24 inThus, the measure of the base is 24 inches.

Step-by-step explanation:
Rachel has an unknown sample of a radioisotope listed in the table. Using a special technique, she is able to measure the mass of just the unknown isotope as 104. 8 kg at 12:02:00 P. M. At 4:11:00 P. M. On the same day, the mass of the unknown radioisotope is 13. 1 kg. Which radioisotope is in the sample? Potassium-42 Nitrogen-13 Barium-139 Radon-220.
Answers
The radioactive isotopes of an element are known as radioisotopes. The radioisotope sample that is given is Barium-139.
What is radioisotope?The radioactive isotopes of an element are known as radioisotopes. Atoms with an unstable mix of neutrons and protons, or excess energy in their nucleus, are also known as neutron-proton atoms.
As it is given that the initial mass of the sample at 12:02:00 PM is,
[tex]m_1=104.8\ kg[/tex]
The Mass of the sample at 4:11:00 PM is given as
[tex]m_2 = 13.1 kg[/tex]
So here since it is a sample of radioactive isotope so here we will say
[tex]m_2=m_1e^{-\lambda t}[/tex]
Now from the above data, we know that the time taken to reduce the mass is
[tex]\rm t = 4\ hours\ 9\ minutes = 4.15\ hours[/tex]
Further, from the above equation, we will have
[tex]13.1 =104.8 e^{-\lambda(4.15)}\\\\\lambda(4.15)=2.08\\\\\lambda = 0.50/ hour[/tex]
So here half-life is given as
[tex]\rm T_{\frac12}=\dfrac{ln2}{\lambda}\\\\ T_{\frac12} = 1.4\ hours[/tex]
Thus, here this isotope must be the one that will have a half-life of 1.4 hours
Therefore, it is nearly Barium-139.
Hence, the radioisotope sample that is given is Barium-139.

Gabby has entered a cooking contest with 6 rounds. In order to earn a medal, she needs a final average score higher than 75. After the first five rounds, her average score is 78. What must her score be in the sixth (final) round to earn a medal? Show your work and answer in a complete sentence.
Answers
Answer:
85
Step-by-step explanation:
We will use the formula
xbar = \sum Xi/N
xbar is the average
N is the number of rounds
\sum Xi is sum of rounds
From the formula:
\sumXi = xbar × N.
If Gabby has entered a cooking contest with 6 rounds and in order to earn a medal, she needs a final average score higher than 75, this means that;
N = 6
xbar = 75+x (since her average needs to be more than 75)
Substitute in the formula
\sumXi = 6(75+x) ....... 1
If after the first five rounds, her average score is 78, then:
At N = 5, xbar = 78
Substitute into the formula
\sumXi = 5(78)
\sumXi = 390..... 2
First we need to get x by equating equation 1 and 2:
6(75+x) = 390
450 + 6x = 390
6x = 390-450
6x = -60
x = -10
Taking x as 10
Since she needs 75+x to earn the medal, substitute x = 10 into the expression:
This means that she will need average score of 75+10 i.e 85 to win the medal
