Answer:
(q + 1)(q + 5p)
Step-by-step explanation:
q² + q + 5pq + 5p
= (q² + q) + (5pq + 5p)
Consider that : q² + q = q(q + 1) and 5pq + 5p = 5p(q + 1)
then
q² + q + 5pq + 5p
= (q² + q) + (5pq + 5p)
= q(q + 1) + 5p(q + 1)
= (q + 1)(q + 5p)
Good luck :)
Final answer:
The expression q^2 + q + 5pq + 5p is factored by grouping into (q + 5p)(q + 1) by factoring out common factors from the grouped terms.
Explanation:
To factor by grouping the expression q2 + q + 5pq + 5p, we need to group the terms in a way that common factors can be factored out.
Firstly, we divide the expression into two groups:
q2 + q5pq + 5pWe can then factor out the common factor from each group:
q2 + q = q(q + 1)5pq + 5p = 5p(q + 1)Now, we can see that the term (q + 1) is common in both grouped expressions:
q(q + 1) + 5p(q + 1)
The expression can be factored as:
(q + 5p)(q + 1)
This is the factored form of the original expression.

3 887 860 round it to the nearest million
4,000,000
because the hundred thousand place value is the digit 5 or higher, the millions rounds up!! in this case, the 3 in the millions rounds up to 4 and the rest of the digits on the right turn to 0, also remember commas!!!!!
3 887 860 rounded to the nearest million is 4 000 000.
From the given number 3 887 860, stating the place value of each digit
We have 0 ones (or unit), 6 tens, 8 hundreds, 7 thousands, 8 ten thousands, 8 hundred thousands and 3 million.
Hence, the number we are rounding is 3 (since we are asked to round to the nearest million)
To round a number, we either round up or round down.
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down; and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
Since, the number that follows the digit we are rounding is 8, then we round up. We round up by adding 1 to the digit we are rounding and turn the remaining numbers to zeros.
(3+1 = 4)
Hence, 3 887 860 rounded to the nearest million is 4 000 000.

What is the distance between (0, 0) and
(8, 15) on the coordinate plane?
A. 7 units
B. 8 units
C. 17 units
D. 23 units
Please help me!!!
Answer:
C. 17
Step-by-step explanation:
Distance formula:
[tex] \sqrt{(x_2 - x_1)^{2} + {(y_2 - y_1)}^{2} } \\ \\ = \sqrt{ {(8 - 0)}^{2} + ( {15 - 0})^{2} } \\ \\ = \sqrt{ {(8)}^{2} + {(15)}^{2} } \\ \\ = \sqrt{64 + 225} \\ \\ = \sqrt{289} \\ \\ = 17[/tex]
The correct answer is C. 17 units.
To find the distance between two points on the coordinate plane, one can use the distance formula derived from the Pythagorean theorem. The distance formula is given by:
[tex]\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \][/tex]
where [tex]\( (x_1, y_1) \) and \( (x_2, y_2) \)[/tex] are the coordinates of the two points.
Given the points [tex]\( (0, 0) \) and \( (8, 15) \)[/tex], we can substitute these values into the formula:
[tex]\[ d = \sqrt{(8 - 0)^2 + (15 - 0)^2} \] \[ d = \sqrt{8^2 + 15^2} \] \[ d = \sqrt{64 + 225} \] \[ d = \sqrt{289} \] \[ d = 17 \][/tex]
Therefore, the distance between the points[tex]\( (0, 0) \) and \( (8, 15) \) is 17[/tex]units.

A bag contains 77 orange marbles and 21 green marbles. If a representative sample contains 33 orange marbles, then how many green marbles would you expect it to contain? Explain. 100 points :)
Because the ratio of orange marbles to green marbles is ___ in the population, the expected number of green marbles is ___ times the number of orange marbles in the representative sample. There should be ___ green marbles.
9 green marbles are expected in the representative sample.
The expected number of green marbles is 0.27 times the number of orange marbles in the representative sample.
Step-by-step explanation:
Given that,
A bag contains 77 orange marbles and 21 green marbles.A representative sample contains 33 orange marbles and the green marbles not known.So, the expected number of green marbles can be assumed as 'x'.The ratio of orange marbles to green marbles is in proportion to the ratio of orange marbles to green marbles in the representative sample.
To find the value of x :
The proportions are 77/21 = 33/x
Cross multiplying the denominators and keeping x alone on one side,
x = (33 × 21) ÷ 77
x = 693 ÷ 77
x = 9 green marbles.
Therefore, the number of green marbles expected in the representative sample is 9.
To find the how many times the green marbles is to the number of orange marbles in representative sample = 9/33 = 0.27 times.
The green marbles is 0.27 times to orange marbles in the representative sample.

I need the value of O and N in the picture (the diagonal lengths)
Answer:
N=15 O=17
Step-by-step explanation:
since we know this is a rectangle and the lines are diagonals we can assume they create right triangles. For line N we set up the Pythagorean Theorem which is a^2 + b^2 = c^2 and to find N we plug in 9 for a and 12 for b. 9^2 + 12^2 = c^2 c^2 = 225 so now we find the square root of c^2 so c or in this case N = 15, now we repeat this same exact sequence for O but N is now our base and 8 is our height of the triangle so we will plug in 8 for a and 15 for b: 8^2 + 15^2 = c^2 c^2 = 289 and the square root of 289 is 17.

A mailbox on the street is 600 feet from the top of a building. From the mailbox looking up to the tops of that building and a second, taller building, the angle between the buildings is 67degrees. The tops of the buildings are 800 feet from each other. If the angle of elevation from the mailbox to the first building is 53 degrees and the taller building is 60 degrees, how tall is each building... Step by step explanation..Please..Thanks
Answer:
first building: 479.2 ftsecond building: 704.2 ftStep-by-step explanation:
Label the mailbox viewpoint, the top of the first building, and the top of the second building points M, A, and B, respectively.
Consider the triangle MAB. You are told length MA is 600 ft, and length AB is 800 ft. Side AB is opposite the 67° angle at M, so we can use the Law of Sines to find other measures of that triangle. Specifically, we want to know the distance MB.
sin(B)/MA = sin(M)/AB
sin(B) = (MA/AB)sin(M) = 600/800·sin(67°) ≈ 0.690379
B ≈ 43.66°
Then the angle at A is ...
180° -67° -43.66° = 69.34°
and the side MB can be found from ...
MB/sin(A) = AB/sin(M)
MB = (sin(A)/sin(M))AB = sin(69.34°)/sin(67°)·800 ≈ 813.2 . . . feet
__
Now, label points on the ground below A and B as A' and B'. This problem is asking for the heights AA' and BB'. Each of these is opposite the angle of elevation to points A and B, respectively, so can be found using the sine relation:
sin(elevation to A) = AA'/MA
AA' = MA·sin(elevation to A) = 600·sin(53°) ≈ 479.2 . . . ft
Similarly, ...
BB' = MB·sin(elevation to B) = 813.2·sin(60°) ≈ 704.2 . . . feet
The first building is 479.2 ft tall; the second is 704.2 ft tall.

(-6, -16)
(−2/3, −16/3)
(-2, -8)
Answer:
(- 6, - 16 )
Step-by-step explanation:
Given the 2 equations
- 4x + y = 8 → (1)
2x - y = 4 → (2)
Adding the 2 equations term by term will eliminate the term in y
- 2x = 12 ( divide both sides by - 2 )
x = - 6
Substitute x = - 6 into either of the 2 equations and soilve for y
Substituting x = - 6 into (2)
2(- 6) - y = 4
- 12 - y = 4 ( add 12 to both sides )
- y = 16 ( multiply both sides by - 1 )
y = - 16
Solution is (- 6, - 16 )

In below diagram, line AB is parallel to CB.
i.e. AB∥CD
∠EGB = 57°
Find ∠EHD.
In the given diagram, line AB is parallel to CB. i.e. AB∥CD ∠EGB = 57°
then the value of ∠EHD = 57°
In this diagram, since AB is parallel to CD, we can infer that ∠EGB and ∠EHD are corresponding angles, and corresponding angles are congruent when a pair of parallel lines are intersected by a transversal. Given that ∠EGB = 57°, we conclude that ∠EHD is also 57° based on the properties of corresponding angles. Thus, ∠EHD = 57°.
When two parallel lines are intersected by a transversal, the corresponding angles formed on either side of the transversal are congruent. In this case, we are given that line AB is parallel to line CD, which implies that ∠EGB and ∠EHD are corresponding angles.
Given: ∠EGB = 57° (Given in the diagram)
Since AB || CD, ∠EGB ≅ ∠EHD (corresponding angles are congruent).
Therefore, ∠EHD = ∠EGB = 57°.
Hence, ∠EHD is also 57° based on the properties of corresponding angles.
In mathematical terms, we use the property of corresponding angles formed by a transversal intersecting two parallel lines to establish the congruence between ∠EGB and ∠EHD. This property is a fundamental aspect of geometry dealing with angles and parallel lines.

A ball is tossed between three friends. The first toss is 8.6 feet, the second is 5.8 feet, and the third toss is 7.5 feet, which takes the ball back to the starting point. What angles are formed by these tosses. Step by Step explanation.. Please
angles formed by these tosses are [tex]79.45, 59.02[/tex] and [tex]41.53[/tex] degrees to the nearest hundredth.
Step-by-step explanation:
Here , We have a triangle with sides of length 8.6 feet, 5.8 feet and 7.5 feet.
The Law of Cosines (also called the Cosine Rule) says:
[tex]c^2 = a^2 + b^2 - 2ab (cosx)[/tex]
Using the Cosine Rule to find the measure of the angle opposite the side of length 8.6 feet:
⇒ [tex]c^2 = a^2 + b^2 - 2ab (cosx)[/tex]
⇒ [tex]c^2 -a^2 - b^2 = -2ab (cosx)[/tex]
⇒ [tex](cosx) =\frac{ c^2 -a^2 - b^2}{ -2ab}[/tex]
⇒ [tex](cosx) =\frac{(8.6^2 - 5.8^2 - 7.5^2)}{ ( -2(5.8)7.5)}[/tex]
⇒ [tex](cosx) =0.18310[/tex]
⇒ [tex]cos^{-1}(cosx) = cos^{-1}(0.18310)[/tex]
⇒ [tex]x = 79.45[/tex]
The Law of Sines (or Sine Rule) is very useful for solving triangles:
[tex]\frac{a}{sin A} = \frac{ b}{sin B} = \frac{c}{sin C}[/tex]
We can now find another angle using the sine rule:
⇒[tex]\frac{ 8.6 }{ sin 79.45} = \frac{7.5}{ sin Y}[/tex]
⇒[tex]sin Y = \frac{(7.5 (sin 79.45))}{ 8.6}[/tex]
⇒[tex]Y = 59.02 degrees[/tex]
So, the third angle =[tex]180 - 79.45 - 59.02 = 41.53 degrees.[/tex]
Therefore, angles formed by these tosses are [tex]79.45, 59.02[/tex] and [tex]41.53[/tex] degrees to the nearest hundredth.
Express 0.15 as a fraction in simplest form.
Final answer:
To express 0.15 as a fraction, write it as 15/100 and simplify by dividing both the numerator and denominator by 5 to get 3/20 in simplest form.
Explanation:
To express the decimal 0.15 as a fraction in its simplest form, we start by writing it as a fraction with a denominator that reflects its place value. Since 0.15 has two digits after the decimal point, its denominator should be 100. Hence, we have:
0.15 = 15/100
Now, we need to reduce this fraction to its simplest form by canceling equivalent terms in the numerator and the denominator. We notice that both 15 and 100 are divisible by 5. Dividing the numerator and the denominator by 5, we get:
15 ÷ 5 = 3
100 ÷ 5 = 20
Therefore, the fraction 15/100 simplifies to 3/20, which is in its simplest form.
Final answer:
To simplify 0.15 as a fraction, convert it to 15/100 and then divide both numerator and denominator by 5 to get the simplest form, which is 3/20.
Explanation:
To express 0.15 as a fraction in simplest form, we start by recognizing that 0.15 is the same as 15 hundredths, which can be written as 15/100. To simplify this fraction, we need to find the greatest common divisor (GCD) of the numerator and the denominator. Both 15 and 100 can be divided by 5, which would give us 3 in the numerator and 20 in the denominator after dividing both by 5. Therefore, the simplest form of the fraction is 3/20.

each of five friends has X action figures in his or her collection. Each friend buys 11 more action figures. Now the five friends have a total of 120 action figures.write an equation that models this problem then solve
Answer:
Each friend has 13 actions
Step-by-step explanation:
Let x represent the actions of each friends
5friends will have 5x actions
And each friend has 11 more actions which means 5(11)=55
It means 5x+55
The total of their actions is 120
It can be written as 5x+55= 120
To solve
5x+55=120
Substrate 55 from both sides
5x=120-55
5x=65
X=65/5
x=13
Which each friend has 13 actions
Final answer:
To model the problem, the equation 5X + 5(11) = 120 is used. Solving this equation leads to finding that the original number of action figures each friend had is X = 13.
Explanation:
Initially, each of the five friends has X action figures in their collection. After purchasing 11 more action figures each, they collectively have a total of 120 action figures. To represent this problem, we can set up an equation where 5 times the original number of action figures per friend, plus 5 times 11 (because each friend buys 11 more), equals 120. Thus, the equation is:
5X + 5(11) = 120
To find the value of X, we need to solve the equation:
Multiply 5 times 11 to simplify the equation: 5X + 55 = 120
Subtract 55 from both sides of the equation: 5X = 120 - 55
Calculate the result on the right side: 5X = 65
Divide both sides by 5 to find X: X = 65 / 5
Thus, the original number of action figures each friend had is X = 13.

The area of a circle is:
a=[tex]\pi[/tex]r^2
Because we have the diameter, we need to find the radius.
d=2r
12=2r
Divide by 2 on both sides
r=6
Plug 6 in for "r" in the area formula.
a=[tex]\pi[/tex]r^2
a=[tex]\pi[/tex]6^2
a=36[tex]\pi[/tex]
a=36*3.14
a=113.04 cm^2
So the answer is choice B
Hope this helps!
