-4(w + 5) + 5w simplify use distributive property
Answer:
w - 20
Step-by-step explanation:
Simplifying the expression:Remove the parenthesis by multiplying each term of (w + 5) by (-4)
-4(w + 5) + 5w = -4*w + 5*(-4) + 5w
= -4w - 20 + 5w
= -4w + 5w - 20
Combine like terms. Like terms have same variable with same power.

Consider the chart of millionaires and population
The number of millionaires Los Angeles should have will be equal to 5,065 millionaires.
Proportion may be defined as part or share of a complete unit compared with respect to the whole unit. A proportion is basically the equality of ratios. Two different ratios can be treated as equals if they are in proportion to each other. Now, the number of millionaires in Los Angeles will be equal to the Proportion of Millionaires in Dubai multiplied by the Population of Los Angeles that is
= 0.00124 × 4,085,014
= 5,065 millionaires

The value of x is 6 degrees.
It is given in the question that:-
HI is parallel to JK and FG is the transversal intersecting HI at L and JK at M.
∠LMK = 115 degrees
∠MLI = (8x + 17) degrees
We have to find the value of x.
We know that,
Angles on the same side of the transversal sum up to 180 degrees.
Hence, we can write,
∠LMK + ∠MLI = 180 degrees.
115 + (8x + 17) = 180 degrees
8x + 132 = 180 degrees
8x = 180 - 132
8x = 48 degrees
x = 48/8 degrees

A cylinder with radius r and height h is inscribed in a cone with radius of 4m and height of 10m. Express the volume V of the cylinder as a function of h.
The volume of the cylinder is 502.4m³
Volume of the cylinder:
Volume of the cylinder can be calculated by the product of the area of base and height.
For any cylinder with base radius ‘r’, and height ‘h’, the volume will be base times the height.
V = πr²h cubic units.
Given,
A cylinder with radius r and height h is inscribed in a cone with radius of 4m and height of 10m.
Here we need to find the volume of the cylinder,
We know that the values of,
Radius = 4m
height = 10m.
Now we have to apply the value on the formula, then we get,
V = π x (4)² x 10
Apply the value of π as 3.14 then we get,
V = 3.14 x 16 x 10
V = 502.4
Therefore, the volume of the cylinder is 502.4 m³.

The value that makes the triangle a valid triangle is x = 17
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:
12x = 204
Divide by 2
x = 17
Hence, the value of x is 17

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]
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%.

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.
