Answer:
$90.00
Step-by-step explanation:
Larrie and Lester went shopping. They both went with equal amount of money.
Let initial amount = x
Larrie = Lester = x
Larrie spent $120.00 and Lester spent $150.00.
Amount left (Larrie) = x - $120.00
Amount left (Lester) = x - $150.00
At the end of the shopping Lester had 2/3 of what Larrie had left.
Amount left (Lester) = 2 / 3 (Amount left (Larrie)
x - 150 = 2/3 (x - 120)
solving for x;
3 (x - 150) = 2 (x - 120)
3x - 450 = 2x - 240
3x - 2x = -240 + 450
x = 210
How much money did Latrine have after shopping?
Amount left (Larrie) = x - $120.00
Amount left (Larrie) = $210.00 - $120.00
Amount left (Larrie) = $90.00
Find the value of x

-12 (-5/6) (-2/15) How do I solve this question I am stuck on an assignment
If a number in parenthesis is directly next to a number without, then the two numbers need multiplied.
-12(5/6)(-2/15) is an example of a double multiplication. But we'll multiply -12 and 5/6 first, then multiply the product by -2/15.
-12x5/6=14 2/5
14 2/5x-2/15=-1 23/25

What is the equation of the line on the graph?
i need help
Answer:
y=-3/2x+2
Step-by-step explanation:
You can find the equation using y=mx+b, where m is the slope and b is the y-intercept. You can see the slope of this line is -3/2, and the y-intercept is 2. If you plug that into the equation, you get y=-3/2x+2

Element X decays radioactively with a half life of 6 minutes. If there are 390 grams of
Element X, how long, to the nearest tenth of a minute, would it take the element to
decay to 28 grams?
y =
= a(.5)^ t/h
Answer:
The time it would take the element to decay to 28 grams is approximately 22.5 minutes
Step-by-step explanation:
The give half life of element X = 6 minutes
The given initial mass of the radioactive element X = 390 grams
The mass of the element X after decay = 28 grams
The function that represent the decay of element X is given as follows here;
[tex]y = a \cdot (0.5)^{\dfrac{t}{h} }[/tex]
Which is of the form;
[tex]N(t) = N_0 \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{1/2}}[/tex]
Therefore;
h = 6 minutes = The time duration of the half life
a = N₀ = The initial mass = 390 g
N(t) = The final mass = 28 g
t = The time it takes the element to decay
Plugging in the values gives;
[tex]28 = 390 \times(0.5)^{\dfrac{t}{6} }[/tex]
[tex](0.5)^{\dfrac{t}{6} } = \dfrac{28}{390}[/tex]
Therefore;
[tex]\dfrac{t}{6} \times ln\left(0.5} \right) = ln \left(\dfrac{28}{390} \right)[/tex]
t/6 = ln(29/390)/ln(0.5)
t = 6 × ln(29/390)/ln(0.5) ≈ 22.496
Given the answer to the nearest tenth of a minute, the time it would take the element to decay to 28 grams, t ≈ 22.5 minutes.

Step-by-step explanation:
If the triangle PQR has sides from biggest to smallest 3,4,5 we need another triangle with a similar ratio to compare it to.
9/3= 3 12/3=4 15/3=5
So the answer is D because I can divide all the sides of the new triangle by the same number to get the sides of triangle PQR
Answer:
D. 9 cm, 12 cm, 15 cmStep-by-step explanation:
Given
ΔLMN ~ ΔPQRΔPQR has sides ratio 3 : 4 : 5

take out the parenthesis which is P

Answer:
15 (A)
Step-by-step explanation:
ok first off you have to remember PEDMAS parentheses,exponents,division.multiplication,addition.subtraction(D and M are from left to right, as well as A and S.)
so the first thing you have to do is 6*2 because it is in the parentheses
this equation turns into
20/4+12-2
now do the division
5+12-2
now you have to add because it is left to right (it doesn't really matter what you o first in this situation)
17-2

state the coordinate of the image of the given point B (-10, -6) under a dilation with a center at the orgin with the given scale factor k = 1/2
The coordinate of the point B ( -10 , -6 ) after the dilation of -1/2 is given by the coordinate B ' ( -5 , -3 )
What is Dilation?Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent
Given data ,
Let the coordinate of the point be represented as B
The value of B = B ( -10 , -6 )
Now , the dilation factor is given by k = 1/2
So , multiply by 1/2 on the x coordinate and y coordinate of the point B , we get
The coordinate of the point B' after the dilation is
B' = B' ( -10/2 , -6/2 )
So , on simplifying the equation , we get
B' = B' ( -5 , -3 )
Hence , the point after dilation is B' ( -5 , -3 )

Monica paid sales tax of $2.40 when she bought a new bike helmet. If the sales tax rate was 6%, how much did the store charge for the bike helmet before tax?
Answer: $40
Step-by-step explanation:
The tax rate is 6% on the price of the good bought.
This means that $2.40 is 6% of the price of the helmet before taxes.
Assuming the before tax price is x, the price of the helmet is:
2.40 = x * 6%
x = 2.40 / 6%
x = $40
$40 is the before tax cost.
