Jimmy bought a refrigerator that cost $525 before tax. He paid 8% of this amount in tax. What was the total cost of the refrigerator including tax?
Answer:
$567 after tax
Step-by-step explanation:
first, let's multiply 525 by 0.08 because he paid 8% (0.08) of 525 in tax.
525(0.08)= 42
now, let's add them together, because the question asks for the total cost.
525+42=567
$567 after tax
Explain which properties you would use to fully expand (the problem in the screenshot)
Answer:
Firs property used : Quotient Property
[tex]log_b(\frac{X}{Y} ) = log_bX -log_bY[/tex]
[tex]log_b(\frac{\sqrt[3]{x} }{36y^2} ) = log_b(\sqrt[3]{x}) - log_b(36y^2)[/tex]
Second property used : Product Property
[tex]log_b(XY) = log_bX + log_b Y[/tex]
[tex]log_b(\sqrt[3]{x}) - log_b(36y^2) = (log_b(\sqrt[3]{x}) - [log_b36 + log_by^2)[/tex]
Third property used : Power Property
[tex]log_b \sqrt[n]{X} = log_b(X)^{\frac{1}{n}} = \frac{1}{n} log_b X[/tex]
[tex](log_b(\sqrt[3]{x}) - [log_b6^2 + log_by^2) = \frac{1}{3} log_bx - 2log_b 6 - 2log_by[/tex]
Fully expanded form:
[tex]log_b(\frac{\sqrt[3]{x} }{36y^2} ) = \frac{1}{3} log_b x-2log_b6-2log_by[/tex]
hey whats the answer to this ? will mark brainliest if correct
Answer:
C. 128°Step-by-step explanation:
Here,
<BAC + <BAE = 180° [Since supplementary angles]
=> 52° + <BAE = 180°
=> <BAE = 180° -52°
=> <BAE = 128° (Ans)
Which of the following is a pair of equivalent radical expressions?
A
45−−√and315−−√
B
75−−√and35√
C
54−−√and96√
D
180−−−√and320−−√
Answer:
correct answer is D i think so
1) Solve for Side A.
2) Solve for Angle B.
Best answer will receive Brainliest.
solution given;
let
AB=a
AC=b=30ft
AB=c=20ft
<A=115°
By using Cosine rule.
a²=b²+c²-2bc cos angle
a²=30²+20²-2*30*20 Cos 115°
a²=1807.1419
a=√[1807.1419]
a=42.51
Side A is 42.51ft.
Again
Cos B=[tex] \frac{a²+c²-b²}{2ac} [/tex]
Cos B=[tex] \frac{42.51²+20²-30²}{2*42.51*20} [/tex]
Cos B=0.7687
<B=Cos -¹(0.7687)
<B=39.46°
Angle B is 39.46°
half-life of Po-210 is 140 days. If the initial mass of the sample is 5
kg, how much will remain after 420 days.
Answer:
[tex]0.625kg[/tex]
Step-by-step explanation:
we are given half-life of PO-210 and the initial mass
we want to figure out the remaining mass after 420 days
in order to solve so we can consider the half-life formula given by
[tex] \displaystyle f(t) = a {0.5}^{t/T} [/tex]
where:
f(t) is the remaining quantity of a substance after time t has elapsed.a is the initial quantity of this substance.T is the half-lifesince it halves every 140 days our T is 140 and t is 420. as the initial mass of the sample is 5 our a is 5
thus substitute:
[tex]\displaystyle f(420)=5\cdot{0.5}^{420/140}[/tex]
reduce fraction:
[tex]\displaystyle f(420)=5\cdot{0.5}^{3}[/tex]
By using calculator we acquire:
[tex]\displaystyle f(420)=0.625[/tex]
hence, the remaining sample after 420 days is 0.625 kg

Ecuacion del siguiente problema: Por 12 envases de plastico de un litro y 5 envases de medio litro de aceite para motor me cobran 92.00 pesos
Answer:
92. p = 12l + 5m donde m = 0.5 l
Step-by-step explanation:
Supongamos que el recipiente de un litro se denota por ly el recipiente de medio litro se denota por m (= 0,5 l), entonces la ecuación se puede escribir como
92. p = 12l + 5m donde m = 0.5l
English
Let the one liter container be denoted by l and half liter container be deonted by m(= 0.5l ) then the equation can be written as
92. p= 12l + 5m where m = 0.5l

Thanks Hope it helps.What is y=4x-29
x+y=1
MUST SHOW WORK!!
Answer:
Hope this helps!! (x,y)=(6,-5)
Answer:
y=-5
x=6
Step-by-step explanation:
substitute y=4x -29 into the equation x+y=1.
x+ 4x-29 = 1
combine like terms
5x-29=1
add 29 to both sides
5x=30
divide by 5
x=6
plug 6 into x in the original equation
y=4(6) - 29
y=24-29
y= -5
