Answer:
1/4
Step-by-step explanation:
The fraction 1/2 of 1/2 is 1/4 so Darcy ingests 1/4 part of a candy bar.
What is a fraction?The fraction is the division of the two numbers but the division is not wholly complete.
If we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.
It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.
Amount of candy Darcy and Jordan have = 1/2
Amount of candy bar Darcy ate = 1/2 of 1/2
⇒ 1/2 (1/2) = 1/4
Hence "The fraction 1/2 of 1/2 is 1/4 so Darcy ingests 1/4 part of a candy bar".

9514 1404 393
Answer:
noyesStep-by-step explanation:
In the equation ...
y = x² +3
the largest variable exponent is 2, which is not 1. The equation is not linear.
__
In the equation ...
y = (1/4)x +7
the largest variable exponent is 1, so the equation is linear.
A kayak is originally priced at $160. The online retailer gives a discount and the kayak is now priced at $88. Enter the percentage discount for the cost of the kayak.
Answer:An important category of percentage exercises is markup and markdown problems. For these, you calculate the markup or markdown in absolute terms (you find by how much the quantity changed), and then you calculate the percent change relative to the original value. So they're really just another form of "increase - decrease" exercises.
Step-by-step explanation:
Answer:
45%
Step-by-step explanation:
O= 160
C=88
160-88=72
72 ?
160 100
72 times 100=7200

Solve the system by substitution. Check your solution.
y = 0.8 x + 7.2.
20 x + 32 y = 48.
a. (8, -6)
b. (5, 11)
c. (-4, 4)
d. (-10, 2)
Answer:
c. (-4, 4)
Step-by-step explanation:
y = 0.8x + 7.2
20x + 32y = 48
20x + 32y = 48
20x + 32(0.8x + 7.2) = 48
20x + 25.6x + 230.4 = 48
45.6x + 230.4 = 48
45.6x = -182.4
x = -4
y = 0.8x + 7.2
y = 0.8(-4) + 7.2
y = -3.2 + 7.2
y = 4

Mary must average at least 30 hours of work per week during each five-week cycle to keep her health benefits. During the first four weeks of the cycle, she has worked 30, 30, 28, and 28 hours. What is the lowest amount of hours she can work in the fifth week to have a weekly average of 30 hours?
Answer:
34 hours
Step-by-step explanation:
given the figures for the work are
30, 30, 28, and 28
we know that average
A= sum of values/number of values
let the fifth value be x
the number of values is now 5
given that A=30
30=30+30+28+28+x/5
cross multiply
150=116+x
x=150-116
x=34 hours

hmmmmmmmmm
Answer:
look at the attached picture
Answer:
X = -16.75
Step-by-step explanation:
Distribute.
(x + 12)23 = 23x + 276
12 + 5x -1 = 11 + 5x
Combine like terms.
23x - 2x - 5x = 16x
11 - (276 + 3+16 ) = -284
16x = -284
x = -17.75

If angle 1 and angle 3 are vertical angles, and m<1= (5x + 14) degrees and m<3= (7x - 4) degrees, what is the value of x, and the measure for angle 1?
Answer:
x = 9
[tex] m\angle 1= 59\degree [/tex]
Step-by-step explanation:
Since, [tex] \angle 1 \:and \:\angle 3[/tex] are vertical angles.
[tex]\therefore m\angle 1 = m\angle 3\\
\therefore (5x + 14) \degree= (7x - 4) \degree\\
\therefore (5x + 14) = (7x - 4) \\
\therefore 5x - 7x = - 4 - 14\\
\therefore -2 x = - 18\\\\
\therefore x =\frac{-18}{-2}\\\\
\huge \orange {\boxed {\therefore x = 9}} \\\\
m\angle 1 = (5x + 14) \degree\\
m\angle 1 = (5\times 9+ 14) \degree\\
m\angle 1 = (45+ 14) \degree\\
\huge \purple{ \boxed{m\angle 1 =59\degree}}[/tex]
Tangela earns the same amount each week by babysitting. When she started this job, she had $200 in her savings account.
The table shows Tangela's savings account balance for her first month of work.
Week 0 1 2 3 4
Balance $200 $350 $500 $650 $800
Let x represent the number of weeks Tangela has been working and let y represent Tangela's account balance.
Which equation, expressed in Slope-Intercept form, represents the amount of money in Tangela's bank account over time?
Answer:
y = 150x + 200
Step-by-step explanation:
Given the table :
Week (x) __ 0 ____ 1 ____ 2 ____3 _____ 4
Balance(y) :$200_ $350_ $500_ $650_ $800
Equation in slope - intercept form:
y = mx + c
Where
x and y are the independent(x) and dependent variables (y)
C = intercept, value of y, when x = 0
m = gradient change in y per change in x
Hence,
c = $200 ; y value when x = 0
m = change in x / change in y
m = (500 - 350) / ( 2 - 1)
m = $150
Hence, equation becomes :
y = 150x + 200

Una escalera está apoyada sobre la pared que mide 3.5m. El pie de la escalera hasta la pared mide 2.5m ¿Cuánto mide la escalera?
Responder:
Explicación paso a paso:
La configuración formará un triángulo de ángulos rectos.
Deje que el pie de la escalera a la pared sean los lados adyacentes = 2,5 m
La altura de la pared será el lado opuesto = 3,5 m
La longitud de la escalera será la hipotenusa.
Usando el teorema de Pitágoras:
hip² = opp² + adj²
hip² = 3,5² + 2,5²
hip² = 12,25 + 6,25
hip² = 6
hip = √6
hip = 2,45 m
Por tanto, la longitud de la escalera es 2,45 m.

The dimensions of the box below are reduced by half. What is the constant of proportionality between the volume of the new box and the volume of the original box? Alternative text A.1/2 B.1/4 C.1/8 D.1/16
Answer:
C. 1/8
Step-by-step explanation:
Dimensions of the Original Box:
Length = 40 inches
Width = 20 inches
Height = 8 inches
Volume of original box = L*W*H = 40*20*8 = 6,400 in³
Dimensions of the New Box (½ of the dimensions of the original box):
Length = ½*40 = 20 in
Width = ½*20 = 10 in
Height = ½*8 = 4 in
Volume of original box = L*W*H = 20*10*4 = 800 in³
Constant of proportionality between the volume of the new box and the volume of the original box = [tex] \frac{800}{6,400} = \frac{1}{8} [/tex]
PLZ HELP LAST QUESTION given the piecewise function given below select all statements that are true f(x)=-x+1,x<0 -2,x=0 x^2-1,x>0 All in brackets A.F(4)=7 Bf(-1)=2 c.F(-2)=0 d.F(1)=0
Answer:
Step-by-step explanation:
Given the function f(x)=-x+1,x<0 and f(x) = x^2-1,x>0
when x = 4
f(4) = -4+1
f(4) = -3
Also f(4) = 4^2 -1
f(4) = 8-1
f(4) = 7
when x = -1
f(-1) = -(-1)+1
f(-1) = 2
Also f(-1) = (-1)^2 -1
f(-1) = 1-1
f(-1) = 0
when x = -2
f(-2) = -(-2)+1
f(-2) = 3
Also f(-2) = (-2)^2 -1
f(-2) = 4-1
f(-2) = 3
when x = 1
f(1) = -1)+1
f(1) = -2
Also f(1) = (1)^2 -1
f(1) = 1-1
f(1) = 0
From the calculation above, the correct statements are
A. F(4)=7
B f(-1)=2
d. F(1)=0
