Answer:
Alex gets £ 30Solution,
Let,
Angad get X
Peter get 3x
Alex get 6x
Now,
[tex]x + 3x + 6x = 50 \\ or \: 10x = 50 \\ or \: x = \frac{50}{10} \\ x = 5[/tex]
Replacing value,
[tex]6x \\ = 6 \times x \\ = 6 \times 5 \\ = 30[/tex]
hope this helps...
Good luck on your assignment..
Answer:
Angad gets £5
Peter gets £15
Alex gets £30
Step-by-step explanation:
Let Angad be x, Then Peter = 3x and Alex = 6x
Condition:
x+3x+6x = 50
=> 10x = 50
Dividing both sides by 10
=> x = 5
So,
Angad gets £5
Peter gets £15
Alex gets £30

For a 4 by 4 cube, he needs 4 rows 4 high for 16 cubes in each row.
The back row is 3 x 4 = 12, so he needs 4 more for the back row,
The 3rd row he has 8, so needs 8 more.
The 2nd row he has 4 so needs 12 more,
The first row he has 2 so will need 14 more.
Total needed: 4 + 8 + 12 + 14 = 38 more cubes.

A.
The surface area of the pyramid is multiplied by 10.
B.
The surface area of the pyramid is multiplied by 50.
C.
The surface area of the pyramid is multiplied by 100.
D.
The surface area of the pyramid is multiplied by 1,000.
E.
The effect on the surface area cannot be determined.
Answer:
C
Step-by-step explanation:
Since the question is asking for surface area and the dimensions are multiplied by 10, the surface area is multiplied by 10^2, or 100. (For area it would be 10^3, or 1000)

Problema:1,745 kilómetros de distancia entre Mérida, Yucatán y Ciudad Victoria, Tamaulipas.1: 100 000 Escala en el mapa.¿Cuántos centímetros representan estos kilómetros en el mapa?
Answer:
1745 centimeters.
Step-by-step explanation:
The first thing is to pass the kilometers to centimeters, we know 1 km equals 100000 cm, therefore:
1745 km * 100000 cm / 1 = 174500000 cm
Now, when applying the scale, we have that it is 1: 100000, so we apply the scale:
174500000 * 1/100000 = 1745
That is to say that on the map those 1745 kilometers represent 1745 centimeters.

Answer:
3. From the graph, g(0) = -1.
4. t(x) = 2x + 5
t(0.5) = 2(0.5) + 5 = 1 + 5 = 6
g(6) = 0 (from graph)
5. 15 = 2x + 5
2x = 10
x = 5
6. g(1) = 0
t(0) = 5
7. t(1) = 7
g(7) = -2
how would you change x + 3y = 18 -3x - 12y = -75 to eliminate y
Answer: [tex]\bold{y=-\dfrac{1}{3}x+6}[/tex]
[tex]\bold{y=-\dfrac{1}{4}x+\dfrac{25}{4}}[/tex]
Step-by-step explanation:
x + 3y = 18
- x -x
3y = -x + 18
÷3 ÷3 ÷3
y = (-1/3)x + 6
-3x - 12y = -75
+3x +3x
-12y = 3x - 75
÷-12 ÷-12 ÷-12
y = (-1/4)x + (25/4)

What is the rate of change between (29,9) and (33,10)?
Answer:
[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
The rate of change is a measure of the slope
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (29, 9) and (x₂, y₂ ) = (33, 10)
m = [tex]\frac{10-9}{33-29}[/tex] = [tex]\frac{1}{4}[/tex] ← rate of change

A $20,000 investment earned a simple interest rate of 5.4%. How much interest was earned in one year?
Answer:
18,920.00
Step-by-step explanation:
discount = x
original price = $20,000
discount% = 5.4%
x/20,000 = 5.4/100
x · 100 = 5.4 · 20,000
100x = 108,000
100x/100 = 108,000/100
x = $ 1,080.00
Sale price = original $ - discount $ = final answer
$20,000 - $1,080 = $18,920.00
Answer:1,080
Step-by-step explanation:
20,000 x .54 equals $1,080
How do I answer this
Answer:
Step-by-step explanation:
A. Model is linear
B. y = -16x - 16
(-3, 32) (-2, 16)
(16-32)/(-2 + 3) = -16/1= -16
y - 32 = -16(x + 3)
y - 32 = -16x - 48
y = -16x - 16

The total number of eggs in k cartons where each carton contains n eggs. Write this as an expression.
｡☆✼★ ━━━━━━━━━━━━━━ ☾
It makes more sense if you think about it in numerical terms.
Say if there were 10 eggs per carton and there were 5 cartons, what would you do to find the total?
You would multiply them
It is the same in this case
The expression would be n x k
It can be written as just nk though

What are the x intercept and the y intercept of this function
Answer:
D
Step-by-step explanation:
When you graph, you can see that the Line crosses the x at (-3,0) and then passes through the y at (0, 12)
Answer:
D
Step-by-step explanation:
To find the intercepts, set the variable you are not trying to find to 0. Also, in case you don't know, f(x) and y are the same thing here. So on this question, it would be:
X-Intercept:
0=4x+12
-12=4x
-3=x
so x intercept is (-3,0)
Y-Intercept:
y=4(0)+12
y=12
so y intercept is (0,12)

The price of the box of 10 markers is $7. The price of the box of 24 markers is $14. All prices without tax, and the price of the boxes is the same. WILL MARK BARINLEIST OR WHATEVER YOU CALL IT I WILL
a) Write an equation which tell the price Y for the number of markers X
The linear equation where y is the price of the number of markers x is as follows:
y = 1 / 2 x + 2Let
the price of each marker = y
Therefore,
The price of a box with 10 markers = $7
The price of a box with 24 markers = $14
(10, 7)(24, 14)
Using linear equation
Slope intercept formy = mx + bwhere
m = slope
b = y-intercept
Therefore,
m = 14 - 7 / 24 - 10
m = 7 / 14
m = 1 / 2
Therefore, let's find b
7 = 1 / 2(10) + b
7 - 5 = b
b = 2
Therefore, the linear equation where y is the price of the number of markers x is as follows:
y = 1 / 2 x + 2learn more on equation here:https://brainly.com/question/12043800
Answer:
y = 1/2x+2
Step-by-step explanation:
We have two points ( 10,7) and (24,14)
We need to determine the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 14-7)/(24-10)
= 7/14
= 1/2
The slope is 1/2
The slope formula is y=mx+b where m is the slope and b is the y intecept
y = 1/2x+b
Using one of the points
7 = 1/2 (10)+b
7 = 5+b
7 -5 =b
2=b
y = 1/2x+2

Answer:
x = 19° ; Write 19° in the box ( don't forgot ° or answer will be incorrect )
Step-by-step explanation:
If XW ║YZ, we can tell that YW is a transversal, as YW ∩ XW, YX;
By alternate interior angles, ∠ ZYW ≅ ∠ YWX, so that ⇒
m∠ ZYW = m∠ YWX,
m∠ YWX = 2x, ⇒ given m∠ ZYW = 2x
By ∑ of angles in triangle Theorem;
m∠ YXW + m∠ XYM + m∠ YWZ = 180° ⇒ through substitution,
( 3x - 5 ) + 90 + ( 2x ) = 180 ⇒ now apply algebra,
3x - 5 + 90 + 2x = 180 ⇒ combine like terms,
3x + 2x - 5 + 90 = 180 ⇒ add,
5x + 85 = 180 ⇒ subtract 85 from either side of equation,
5x = 95, divide 5 on either side,
x = 19°
Solution; x = 19°

liz is installing a tile backsplash. if each tile is an equilateral triangle with sides that measures 6 cm in length how many tiles does she need to cover an area of 1800 cm²
Answer:
116 tiles
Step-by-step explanation:
You want to know the number of 6 cm equilateral triangle tiles required to cover 1800 cm².
AreaThe area of an equilateral triangle of side s is given by the formula ...
A = (√3/4)s²
The area of a 6 cm equilateral triangle tile is ...
A = (√3/4)(6 cm²) = 9√3 cm² ≈ 15.588 cm²
TilesThe number of tiles required is the total area divided by the area per tile:
1800 cm² / (15.588 cm²/tile) ≈ 115.47 tiles
In order to cover 1800 cm², Liz will need 116 triangular tiles.
Answer:
100 tiles
Step-by-step explanation:
Each tile is an equilateral triangle with sides 6 cm in length, so the area of each tile can be found using the formula for the area of a triangle:
[tex]\sf:\implies{A = (b \times h) / 2}[/tex]
where b is the base and h is the height.
Since each side of the triangle is 6 cm, the base and height of the triangle are both 6 cm, so:
[tex]\sf:\implies{A = (b \times h) / 2}[/tex]
[tex]\sf:\implies{A = (6 \times 6) / 2}[/tex]
[tex]\sf:\implies{A =18}[/tex]
So each tile has an area of 18 cm².
To find the number of tiles needed to cover an area of 1800 cm², divide the total area by the area of each tile:
[tex]\sf:\implies{A = 1800 / 18}[/tex]
[tex]\sf:\implies{A = 100}[/tex]
Therefore, Liz needs 100 tiles to cover an area of 1800 cm².
Can a right triangle have the measurements of 8,11, and 13?
Answer:
yes it can
Step-by-step explanation:
yes
Answer:
No
Step-by-step explanation:
You need to use the Pythagorean Theorem. This will show you if the ratio between the sides is accurate.
a² + b² = c²
8² + 11² = 13²
64 + 121 = 169
185 ≠ 169
The measurements will not fit in a right triangle.
