In a list of five consecutive odd integers, the sum of the first and double the last is 139. What is the largest sum?
Answer: 49
Step-by-step explanation:
From your question, I think you mean the largest number. The answer is given below.
Let the five consecutive odd numbers be:
a, a+2, a+4, a+6 and a+8.
Thee sum of the first and double the last is 139. This can be written as:
a + 2(a+8) = 139
a + 2a + 16 = 139
3a + 16 = 139
3a = 139 - 16
3a = 123
a = 123/3
a = 41
The first number = 41
The largest number = a+8 = 41 + 8 = 49.

Two angles form a linear pair. The measure of one angle is 24º more than the measure of the other angle. Find the measure of each angle.
Answer:
The measures of the two angles are 78° and 102°
Step-by-step explanation:
When two lines intersects at a point, then pairs of linear angles are formed
The linear pair of angles are adjacent angles the sum of their measures is 180°∵ The two angles form a linear pair
∴ The sum of the two angles = 180°
∵ The measure of one of them = 24° more than the measure
of the other angle
→ Assume that the smaller one is x, then the greater one is
x + 24, add them up and equate their sum by 180°
∵ x + x + 24 = 180
→ Add the like term in the left side
∴ 2x + 24 = 180
→ Subtract 24 from both sides
∴ 2x + 24 - 24 = 180 - 24
∴ 2x = 156
→ Divide both sides by 2
∴ 2x/2 = 156/2
∴ x = 78°
∴ The smaller angle = 78°
∵ The larger angle is x + 24
∴ The larger angle = 78 + 24 = 102°
The measures of the two angles are 78° and 102°
The five-number summary of the distribution of scores on the final exam in Psych 001 last
semester was min =18 Q = 39 Med = 62 Q = 76 Max = 100. A total of 416 students
took the exam. About how many students had scores above
39? (A) 104
(B) 208
(C) 312
(D) 400
First quartile of the distribution is, Q = 39.
i.e 75% of students have scored more than 39.
So, total number of students scored more than 39 are :
[tex]n=\dfrac{416\times 75}{100}\\\\n=312[/tex]
Therefore, number of students scored higher than 39 are 312.
Hence, this is the required solution.

Point S is on line segment RT. Given RS = 4x – 10, ST = 2x – 10, and
RT = 4x – 4, determine the numerical length of RS.
Answer:
The numerical length of RS is 22 units
Step-by-step explanation:
∵ Point S is on the line segment RT
→ That means S divide RT into two parts RS and ST
∴ RS + ST = RT
∵ RS = 4x - 10
∵ ST = 2x - 10
∵ RT = 4x - 4
→ Substitute them in the statement above
∴ 4x - 10 + 2x - 10 = 4x - 4
→ Add the like terms in the left side
∴ (4x + 2x) + (-10 + -10) = 4x - 4
∴ 6x + (-20) = 4x - 4
∴ 6x - 20 = 4x - 4
→ Add 20 to both sides
∴ 6x -20 + 20 = 4x - 4 + 20
∴ 6x = 4x + 16
→ Subtract 4x from both sides
∴ 6x - 4x = 4x - 4x + 16
∴ 2x = 16
→ Divide both sides by 2 to find x
∴ [tex]\frac{2x}{2}=\frac{16}{2}[/tex]
∴ x = 8
→ Substitute the value of x in Rs to find its length
∵ RS = 4(8) - 10
∴ RS = 32 - 10
∴ RS = 22 units
The numerical length of RS is 22 units

1. Cuando se compra pintura ,por la general , se venden galones(un galón equivale a 3.7354L)y se reparten en botes de 1/4L o otra fracción de litro. a) Si compro dos galones y debes repartirlos en botes de 1/4L¿comó sabes cuántos botes pueden llenar?
Answer:
Se requiere 30 botes de 0.25 litros para dos galones de pintura.
Step-by-step explanation:
Sabemos que un galón equivale a 3.7354 litros, para estimar en cuantos botes de 0.25 litros se puede distribuir dos galones, empleamos la siguiente expresión:
[tex]n = \frac{V_{total}}{V_{bote}}[/tex]
Donde:
[tex]V_{bote}[/tex] - Volumen del bote, expresado en litros.
[tex]V_{total}[/tex] - Volumen total, expresado en litros.
[tex]n[/tex] - Cantidad de botes a llenar, adimensional.
Si sabemos que [tex]V_{bote} = 0.25\,L[/tex] y [tex]V_{total} = 2\,gal[/tex], entonces:
[tex]n = \frac{(2\,gal)\cdot \left(3.7354\,\frac{L}{gal} \right)}{0.25\,L}[/tex]
[tex]n = 29.883[/tex]
Puesto que la cantidad de botes es representada por un número entero,la cantidad requerida se redondea por exceso al entero más cercano. En consecuencia, se requiere 30 botes de 0.25 litros para dos galones de pintura.
Which regular polygons could be used to make regular and semi-regular tessellations? Check all that apply.
- equilateral triangle
- square
- regular pentagon
- regular hexagon
- regular octagon
- regular nonagon
- regular dodecagon
Answer:
A. equilateral triangle
B. square
D. regular hexagon
E. regular octagon
G. regular dodecagon
Step-by-step explanation:
The regular polygons could be used to make regular and semi-regular tessellations are equilateral triangle, square and regular hexagon. Therefore, the correct answers are A, B and D.
A regular tessellation is tessellation made up by using only one type of regular polygon. These are made up of completely congruent regular polygons all that connecting vertex to vertex.
Regular polygons have congruent straight sides. When we slide or rotate a regular polygon, the side of the original figure and the side of its translation will match.
Equilateral triangles, squares and regular hexagons are the only regular polygons that tessellate. Therefore, there are only three regular tessellations.
Therefore, the correct answers are A, B and D.

if EG=10x+20, FG=43. EG=183, find the value of x.
Answer:
Option (3)
Step-by-step explanation:
Given: EF = 10x + 20
FG = 43
EG = 183
From the figure attached,
Length of segment EF + length of segment FG = length of segment EG
By substituting the values of each segment in the equation,
(10x + 20) + 43 = 183
10x + 20 = 183 - 43
10x = 140 - 20
x = [tex]\frac{120}{10}[/tex]
x = 12
Therefore, x = 12 will be the answer.
Option (3) will be the correct option.
Sanjai had $175 in his bank account before he got paid this week
His current balance is $287. How much did he get paid?
Answer:
$112
Step-by-step explanation:
To find the amount he got paid, subtract the current amount from the initial amount
so
287 - 175
= 112
Hey there!☺
[tex]Answer:\boxed{\$112}[/tex]
[tex]Explanation:[/tex]
Sanjai had $175 in his bank account before he got paid this week. And now his total is $287. Represent x as how many he got after he paid. So that means you do $175 + x = $287.
[tex]175+x=287[/tex]
We have to find x and see how much money he got paid to get 287 in his balance.
[tex]287-175=112[/tex]
x is equal to 112. Let's see if $112 makes x true.
[tex]175+112=287[/tex]
That makes x true which means he got paid $112.

Derek invests £154 500 for 2 years at 4% per year compound interest.
Work out the value of the investment at the end of 2 years.
Answer:
p=£154,500
T=2years
R=4%
Compound Amount (CA) =?
Now,
CA=p(100+R/100)^T
=154500*(100+4/100)^2
=154500*(104/100)^2
=154500*(1.04)^2
=154500*1.0861
=167107.2
Therefore The value of the investment will be £167107.2 after 2year
The value of the investment at the end of 2 years is £167107.2.
Given that, principal =£154500, time period= 2 years and rate of interest =4%.
What is the compound interest?Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
The formula used to find the compound interest = [tex]Amount=P(1+\frac{R}{100} )^{nt}[/tex]
Here, Amount = 154500(1+4/100)²
= 154500(1+0.04)²
= 154500(1.04)²
= 154500×1.0816
= £167107.2
Hence, the value of the investment at the end of 2 years is £167107.2.

where a is scaling factor, which means, it moves the values of [tex]x^{b}[/tex] up or down;

The difference between exponential and power functions, is that in power functions, a variable base is elevated to a fixed exponent.
