Brandon has seven pieces of chocolate.
He gives Colton one piece and Jill three pieces.
What fraction of chocolate does Brandon have now?
Answer:
4/7
Step-by-step explanation:
Answer:
Brandon has [tex]\frac{3}{7}[/tex] of the chocolate left with him.
Step-by-step explanation:
Step 1: Identify the fractions
Colton is given one of the seven pieces, so he has [tex]\frac{1}{7}[/tex] of the chocolate.
Jill is given three of the seven pieces, so she has [tex]\frac{3}{7}[/tex] of the chocolate.
Brandon himself had seven pieces at the beginning, so he had [tex]\frac{7}{7}[/tex] (the whole) of the chocolate.
Step 2: Do calculations with the fractions
Collectively, Colton and Jill have taken:
[tex]\frac{1}{7}+\frac{3}{7}\\\\\text{Add the fractions:}\\\frac{1+3}{7}\\\\\text{Calculate:}\\\frac{4}{7}~\text{of the chocolate}[/tex]
So, the fraction that Brandon has currently is:
[tex]\frac{7}{7}-\frac{4}{7}\\\\\text{Subtract the fractions:}\\\frac{7-4}{7}\\\\\text{Calculate:}\\\frac{3}{7}[/tex]
Brandon has [tex]\frac{3}{7}[/tex] of the chocolate left with him.

How is solving 2x + c= d similar to solving 2x + 1= 9 for x?
Solving 2x+c = d is similar to solving 2x+1 = 9 because both the equations have similar pattern.
According to the question,
We have thee following two equations:
2x+c = d ....(1)
2x+1 = 9 ....(2)
Now, note in these equations that in equation 2 we have two different values of c and d. We have the value of c as 1 and d as 9.
Further, solving these two equations would be same because of the following:
For equation 1, we have:
2x+c = d
2x = d-c
x = (d-c)/2
For equation 2, we have:
2x+1 = 9
2x = 9-1
x = (9-1)/2
Now, observe that in finding the values of x in both the equations we have similar solutions except the fact that in equation 2 we have two values of c and d.
Hence, solving 2x+c = d and 2x+1 = 9 is similar.

Two consecutive integers have a sum of 77. What are the two integers?
Answer: 38 and 39
if you add them together you get 77
Answer:
38 & 39
Step-by-step explanation:
Forming the equation,
→ x + (x + 1) = 77
→ 2x + 1 = 77
Now the value of x will be,
→ 2x + 1 = 77
→ 2x = 77 - 1
→ x = 76/2
→ [ x = 38 ]
Then the required integers are,
→ x = 38
→ x + 1 = 38 + 1 = 39
Hence, the integers are 38, 39.

What are angles?Angles are formed when two or more lines intersect.
This in other words means that angles is the measure of space between the intersection of rays or lines
How to determine the measure of x?The given parameters are
Shape = Triangle STU
Angle S = 6x - 15
Angle T = 2x - 2
Angle U = 4x - 7
The sum of angles in a triangle is 180 degrees
This means that
Angle S + Angle T + Angle U = 180
Substitute the known values in the above equation
So, we have the following:
6x - 15 + 2x - 2 + 4x - 7 = 180
Evaluate the like terms in the equation
So, we have the following:
12x = 180 + 15 + 2 + 7
Evaluate the like terms in the equation
So, we have the following:

parallelogram. Round your answer to the nearest tenth if necessary.

Perimeter of the parallelogram which points are E(7,-5), F(7, 2), G(4, 8), and H(4, 1) = 24 units.
There are 4 types of parallelograms, including 3 special types. The four types are parallelograms, squares, rectangles, and rhombuses.
A parallelogram is a shape with only two dimensions. It has four sides, two parallel pairs of which make up each side. The lengths of the parallel sides are also the same. The form is not a parallelogram if the lengths of the parallel sides are not equal.
Properties of parallelograms
Opposite sides are congruent (AB = DC).Opposite angels are congruent (D = B).Consecutive angles are supplementary (A + D = 180°).If one angle is right, then all angles are right.The diagonals of a parallelogram bisect each other.Given points are
E(7,-5),
F(7, 2),
G(4, 8), and
H(4, 1)
Perimeter of the parallelogram EFGH=2(EF+FG)
Distance between two points(x₁ , y₁) and (x₂ , y₂ ) can be calculated using the formula
√(x₂ - x₁ )² + (y₂ - y₁)²
Hence ,length of EF =
√(7 - 7 )² + (2 - (-5))²
=√49
=7units
And length of FG =
√(4 - 7 )² + (8 - 4)²
= √16 + 9
= √25
=5units
Hence, Perimeter of the parallelogram EFGH=2(EF+FG)=2(5+7)=24units

Answer:
27.4 units
Step-by-step explanation:
Given parallelogram EFGH with vertices E(7,-5), F(7, 2), G(4, 8), and H(4, 1), you want to know its perimeter.
Distance between two pointsThe distance between two points can be found from their coordinates using the distance formula ...
d = √((x2 -x1)² +(y2 -y1)²)
ApplicationThe distance between points F and G is ...
d = √((4 -7)² +(8 -2)²) = √(9 +36) = √45 ≈ 6.708
The distance between points E and F will be the difference of their y-coordinates:
d = √((7 -7)² +(2 -(-5))²) = √(0 +7²) = 7
PerimeterSince opposite sides of a parallelogram are the same length, the perimeter is twice the sum of two adjacent sides:
P = 2(EF +FG)
P = 2(7 +6.708) = 2(13.708) = 27.416
The perimeter of EFGH is about 27.4 units.

A financial planner has a client with 16000$ to invest. If he invests $10,000 in a certificate of deposit paying 12% annual simple interest, at what rate does the remainder of the money need to be invested so that the two investments together yield at least $1620 in yearly interest?
As per the Simple interest concept, at 7% of rate the remainder of the money need to be invested so that the two investments together yield at least $1620 in yearly interest.
Simple interest.
Simple interest is calculated by multiplying the daily interest rate by the principal by the number of days that elapse between payments.
Given,
A financial planner has a client with 16000$ to invest.
Here we need to calculate the rate does the remainder of the money need to be invested so that the two investments together yield at least $1620 in yearly interest when he invests $10,000 with the annual simple interest 12%.
Let us consider R represents the rate that remainder of money needs to be invested
Here we know that, $10,000 is invested at 12%
So, according to the formula the interest at 12% is evaluated as,
=> $10,000 * 0.12 * 1 = $1200
And the remaining $6000 is invested at R%
Then the interest at R%=$6000 * R * 1 = $6000R
Now we need to find that the two investments together need to yield at least $1620, so our equation to solve is:
$1620 = $1200 + $6000R
Now, we have to subtract $1200 from both sides, then we get,
$1620 - $1200=$6000R
Then collect similar terms
$420=$6000R
Now, divide both sides by $6000
R=0.07 or 7%
Therefore, the answer is 7%.

A bag contains 6 red marbles and 4 yellow marbles. A marble is drawn at random and not replaced. Two further draws are made, again without replacement.
What is the probability of drawing at least one red marble?
Answer:
6/10
Step-by-step explanation:
I think, however I may be very wrong, sorry.
Answer:
[tex]\sf \dfrac{29}{30}[/tex]
Step-by-step explanation:
A bag contains:
6 red marbles.4 yellow marbles.Therefore, the total number of marbles in the bag is 10 marbles.
The possible outcomes for drawing 3 marbles (without replacement) are:
R R RR R YR Y RR Y YY R RY R YY Y RY Y YTherefore, the only outcome where at least one red marble is not drawn is {Y Y Y}.
To find the probability of drawing at least one red marble, subtract the probability of drawing 3 yellow marbles from one.
The probability of drawing 3 yellow marbles without replacement is:
[tex]\implies\sf P(3\; yellow \;marbles)=\dfrac{4}{10} \times \dfrac{3}{9} \times \dfrac{2}{8}=\dfrac{24}{720}=\dfrac{1}{30}[/tex]
Therefore, the probability of drawing at least one red marble is:
[tex]\implies \sf P(At\;least\;one\;red\;marble)=1-\dfrac{1}{30}=\dfrac{29}{30}[/tex]
This can be confirmed by drawing a tree diagram (see attached).
To find the probability of drawing at least one red marble, add the probabilities at the end of each relevant final branch:
[tex]\begin{aligned}\implies \sf P(At\;least\;one\;red\;marble)&=\dfrac{1}{6}+\dfrac{1}{6}+\dfrac{1}{6}+\dfrac{1}{10}+\dfrac{1}{6}+\dfrac{1}{10}+\dfrac{1}{10}\\\\&=\dfrac{4}{6}+\dfrac{3}{10}\\\\&=\dfrac{20}{30}+\dfrac{9}{30}\\\\&=\dfrac{29}{30}\end{aligned}[/tex]
