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.

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.

Answer:

-1/2

Step-by-step explanation:

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.

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%.

The slope of the line above is -2.

The slope of a line can be defined as the change in y with respect to the change in x .

The slope can be regarded as rise over run.

The slope can be express in mathematical form as follows;

slope = m = y₂ - y₁ / x₂ - x₁

using the coordinates on the graph,

(0, 3)(3, - 3)

x₁ = 0

x₂ = 3

y₁ = 3

Considering the equation of selling habitat between Niayla and Hamilton, the number of habitats that Niayla and Hamilton must sell to make an equal amount of money is 15

information gotten from the question include

Hamilton gets paid a flat fee of 350 dollars plus 50 dollars for each habitat he sells

Niayla gets paid a flat fee of 500 dollars 40 dollars for each habitat she sells

The equation as described is a linear function and is represented by the form. y = mx + c

where:

y = total amount made

x = number of habitat sold

m = cost per habitat

c =flat fee

some interpretation on the information from the question include

for Hamilton

y = 50x + 350

for Niayla

y' = 40x + 500

To make equal amounts y = y'

50x + 350 = 40x + 500

500 - 350 = 50x - 40x

150 = 10x

x = 150 / 10

Answer:

3.5 * 10^2

Step-by-step explanation:

So you start with 350.

What you do is take the decimal from the beginning of 350 and move it to the left.

350.0 -> 35.0-> 3.5

And you move the decimal until you get only one number in front of the decimal.

Then you take the number of times you moved the decimal and put it with ten so in this case it would be. 10^2.

Making the final answer: 3.5 * 10^2

∠UXS = ?

As we know that a line make 180 degree angle on it.

So, ∠UXS + ∠RXU = 180°

     ∠UXS =  180° -  ∠RXU

The value that makes the triangle a valid triangle is x = 17

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

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:

12x = 204

Divide by 2

x = 17

Hence, the value of x is 17

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

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.

The distance between two points can be found from their coordinates using the distance formula ...

  d = √((x2 -x1)² +(y2 -y1)²)

The 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

Since 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.

Answer:

[tex]\sf \dfrac{29}{30}[/tex]

Step-by-step explanation:

A bag contains:

Therefore, the total number of marbles in the bag is 10 marbles.

The possible outcomes for drawing 3 marbles (without replacement) are:

Therefore, 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]
