The diagram represents a reduction of a triangle by using a scale factor of 0.8.
What is the height of the reduced triangle?
A) 4.0 inches
B) 4.8 inches
C) 5.2 inches
D) 7.5 inches
Answers
Answer:
B 4.8 inches
Step-by-step explanation:
The scale factors are used to convert a figure into another one with similar characteristics but different lengths, in this example is a triangle, and in order to calculate the measure of the height you just have to multiply the original height by the scale factor:
Write an expression to show how much it costs per week to keep the 8 adults x where the number of pounds one adults in a day. Simplify your expression
Answers
Answer:
y = 56xStep-by-step explanation:
Given the amount to keep one adult in a day to be x
Since 7 days = 1 week
Amount it will take to keep one adult for a week will be 7x
one adult = 7x pounds
To get the expression that show how much it costs per week to keep the 8 adults, we will say;
8 adults = y pounds
where y is the required amount
Solving both expressions
one adult = 7x pounds
8 adults = y pounds
Cross multiply
1 * y = 7x * 8
y = 56x
Hence the required expression is y = 56x

In order to solve for x, first combine both fractions on the left
To add 4x-2/8 + 3+x/4 first find the least common denominator of 8 and 4
It's 8 so multiply the numerator and denominator of 3+x/4 by 8, you would get:
8x+24/32
Multiply 4x-2/8 by 4, you will get:
16x-8/32
Now you can add 16x-8/32 + 8x+24/32, you would get:
24x+16/32
Now you can start to solve for x
Your new equation is 24x+16/32 = 1/2
To solve for x, first multiply diagonally, then solve like a regular equation.
Multiply 24x+16 by 2 to get 48x+32
Then multiply 32 by 1 to get 32
Your new equation is 48x+32=32
Now subtract 32 by 32 to get 48x=0
Now divide 48 by 0 to get x=0

Find the diagram attached
From the diagram, the sum of angle of the straight line BCD is 180°. Hence;
<BCE+<ECF<90 = 180
<BCE+64+90=180
<BCE+154 = 180
<BCE = 180-154
<BCE = 26°
Next is to get x.
The sum of interior angles <BCE and <BEC is equal to exterior angle <ABE
<BCE + <BEC = <ABE
26+x = 3x
Collect like terms
26 =3x-x
26=2x
x = 26/2
x = 13
Hence the value of x is 13

Annette, Barb, and Carlita work in a clothing shop. One day the three had combined sales of $1480. Annette sold $140 more than Barb. Barb and Carlita combined sold $320 more than Annette. How much did each person sell?
Answers
Barb sold $440
Carlita sold $460
Whixh adds up to the total amount of $1480
Annette sold 580 which is 140 more than barb so 580-140= 440. Barb a carlita combined sold 320 more than Annette. We know Annette sold 580 so 580 +320 = $900 which it the combined total of what barb and carlita sold. We know barb sold 440 so 900-440= 460 which is the total amount that carlita sold.

Step-by-step explanation:
divide both sides by -2
-2(2x+y)/-2=28/2
simplify
2x+y=-14
subtract y from both sides
2x+y-y=-14-y
simplify
2x=-14-y
divide both sides by 2
2x/2=-14/2-y/2

The answer would be 80 black marbles.
Step-by-step explanation:
The student chose 10 marbles. 8 of those were black. There are 100 marbles total. Going at this rate, picking 10 at a time, 10x10 is 100. So we would do this 10 times. 8x10 is 80. 2x10 is 20. There are 80 black marbles.

¿Cuál debe ser el precio de venta de cada lápiz para que el ingreso total sea máximo? El ingreso total l(v) que se obtiene por la venta de lapices esta dado por la función l(v)=-2v^2+500v, donde v es el precio de venta de cada lápiz en pesos.
Answers
Responder:
125 pesos
Explicación paso a paso:
Dado el ingreso total l (v) obtenido de la venta de lápices por la función
Yo (v) = - 2v ^ 2 + 500v
v es el precio de venta de cada lápiz
Para que el ingreso total sea máximo, entonces dI / dv debe ser cero, es decir, dI / dv = 0
dI / dv = -4v + 500
Dado que dI / dv = 0
0 = -4v + 500
4v = 500
Dividir entre 4
4v / 4 = 500/4
v = 125
De ahí que el precio de venta de cada lápiz sea para que el ingreso total sea máximo es de 125 pesos
Identify the method that will be used to solve for x for each equation. 4r = 20 x-11 = 9 5x + 6x = 22 5(x - 2) = 30
Answers
for x - 11 = 9 you have to use the addition property of equality add 9 to 11
for 5x + 6x = 22 you have to combine like terms add 5x and 6x to make 11x
for 5(x – 2) = 30 you have to use the distributive property multiply 5 and x; 5 and -2
4x = 20; x = 5
x - 11 = 9; x = 20
5x + 6x = 22; 11x = 22; x = 2
5(x – 2) = 30; 5x - 10 = 30; x = 8

Answer:
a = 26 or 21.82
Step-by-step explanation:
If 'a' is the hypotenuse, then ...
a² = b² +c²
a² = 24² +10² = 576 +100 = 676
a = √676 = 26 . . . if 'a' is the hypotenuse
__
If 'a' is the long side, then ...
b² = c² + a²
b² -c² = a² = 24² -10² = 576 -100 = 476
a = √476 ≈ 21.82 . . . if 'a' is the long leg

what are the slope and y-intercept for the graph of y-3x=-1
Answers
to do that, you have y - 3x = -1
you want to get y alone so add 3x to both sides
you’ll get y= 3x -1
so your m (slope) is 3
now your y intercept is always your constant which in this case is -1
answer: slope= 3x
y intercept: -1
Answer:
Step-by-step explanation:
Think of the equation y = mx + b
So the m is the slope and the b is the y-intercept
m/slope= 3 b/y-intercept= -1

Given the following functions, find the indicated values.
f(x) = 2 -5x
(a) f(-6) (b) f(0) (c) f(9)
(a) f(- 6) = 2
(b) f(0) =
(c) f(9) =
Answers
Answer:
f(-6) = 32
f(0) = 2
f(9) = -43
Step-by-step explanation:
Since in this question we are given a function all we have to do is to plug in the values that were indicated in the question and find out what value are we going to get as an output of this function. So we just do the following.....
a)
f(-6) = 2 - 5(-6)
f(-6) = 2 - (-30)
f(-6) = 2 + 30
f(-6) = 32
b)
f(0) = 2 - 5(0)
f(0) = 2 - 0
f(0) = 2
c)
f(9) = 2 - 5(9)
f(9) = 2 - 45
f(9) = -43
