Answer:
28 nickels and 52 dimes
Step-by-step explanation:
.05x 28 + .10 x 52 = 6.60
1.40 + 5.20 = 6.60
^28 + ^52 = ^80

4(a + 2) + 2 = 4 - 2(-2a - 3)
Answer:
0=0
Step-by-step explanation:
4(a + 2) + 2 = 4 - 2(-2a - 3)
4a + 8 + 2 = 4 + 4a + 6
4a + 10 = 10 + 4a
0 = 0

1. Un arquitecto construirá una casa de interés social en un área rectangular de 52 m². El
frente será el ancho de la casa y el largo será dos veces el ancho.
a.
Traza una figura geométrica que represente el terreno
b.
¿Cuál es la variable con la que representarías el ancho?
Answer:
Definamos:
A = Ancho
L = Largo.
Sabemos que el área es rectangular, y para un rectángulo de ancho A y largo L, el área es:
Área = A*L.
Y sabemos que L = 2*A.
a) Una imagen se encuentra abajo.
b) Como podemos escribir la variable L en términos de la variable A, podemos escribir:
Área = A*L = A*(2*A) = 2*A^2
Entonces la variable que usamos es el ancho.
Ahora podemos resolver el problema:
52m^2 = 2*A^2
52m^2/2 = 26m^2 = A^2
A = √(26m^2) = 5.1 m
Entonces el largo es:
L = 2*A = 2*5.1m = 10.2 m

Enter the slope-intercept equation for the image of line ℓ after a clockwise rotation of 90°. (Hint: To find the image of line ℓ, choose two or more points on the line and find the images of the points.)
Answer:
y = -2x - 2
Step-by-step explanation:
From the graph attached,
If the line 'l' passes through two points A(0, -1) and B(4, 1).
Rule for the rotation of any point (x, y), 90° clockwise about the origin is,
(x, y) → (y, -x)
By this rule,
A(0, -1) → A'(-1, 0)
B(4, 1) → B'(1, -4)
Let the equation of the line A'B' is,
y - y' = m(x - x')
where m = slope of the line A'B'
And (x', y') is a point lying on the line.
Slope of the line passing through A' and B' will be,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{0+4}{-1-1}[/tex]
m = -2
Therefore, equation of the line passing through (-1, 0) and slope = -2,
y - 0 = (-2)(x + 1)
y = -2x - 2
So the equation of the line after rotation of lie 'l' by 90° clockwise will be,
y = -2x - 2
Given a linear equation with a slope of - 13/4, determine the slope of a line that is perpendicular. Enter the answer as a fraction.
Answer:
4/13
Step-by-step explanation:
To find the perpendicular slope, find the negative reciprocal, which is 4/13 in this case. All you do is flip the numerator and denominator, and change the sign.
Answer:
4/13 should be the answer as it is the reciprocal.

Answer:
r = 1
Step-by-step explanation:
Solving the equation for r gives ...
r = y/x
Using the first line of the table, we find r to be ...
r = 5.8/5.8 = 1
The constant of proportionality is r = 1.
There are two necklaces Maria wants to buy. One is $28.66 and the other is $19.39. She has a coupon for $5 off the total bill when you purchase two items. If she buys both, how much will she owe before taxes?
Answer:
$43.05

Ashley has sold 70% of the 20 candy bars she is supposed to sell for her softball team. How many candy bars does she have left to sell?
Answer:
70/100=x/20 cross multiply you get 1400/100=14
If Ashley sold 70% of her candy bars it means she has 30% left to sell
of means times

What is the equation of this graphed line? If the line passes through (-6,-3) and (6,-7)
Answer:
y= -1/3x - 5
Step-by-step explanation:
Answer:
The answer would be y=-1/3x-7.
Step-by-step explanation:
Using the formula y2-y1/x2-x1 to find the slope of the line, plug in the numbers and you will get a slope of -1/3. Now using the the formula y-y1=m(x-x1) and plug in the numbers, and you will get the equation y=-1/3x-7.
