Answer:
They have 425 candy bars ready to sell.
Step-by-step explanation:
Let,
x be the number of candy bars ready to sell
y be the number of chips ready to sell
According to given statement;
x+y=575 Eqn 1
x+0.5y= 500 Eqn 2
Subtracting Eqn 2 from Eqn 1
(x+y)-(x+0.5y)=575-500
x+y-x-0.5y=75
0.5y = 75
Dividing both sides by 0.5
[tex]\frac{0.5y}{0.5}=\frac{75}{0.5}\\y=150[/tex]
Putting y=150 in Eqn 1
x+150 = 575
x = 575-150
x = 425
Hence,
They have 425 candy bars ready to sell.

Element X is a radioactive isotope such that every 51 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 7500 grams, how long would it be until the mass of the sample reached 6900 grams, to the nearest tenth of a year?
Answer: It will take 6 years for 7500 grams of X to reach 6900 grams.
Step-by-step explanation:
Expression for rate law for first order kinetics is given by:
[tex]t=\frac{2.303}{k}\log\frac{a}{a-x}[/tex]
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant
a - x = amount left after decay process
a) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
[tex]51=\frac{0.69}{k}[/tex]
[tex]k=\frac{0.69}{51}=0.0135years^{-1}[/tex]
b) for 7500 g to reach to 6900 g
[tex]t=\frac{2.303}{0.0135}\log\frac{7500}{6900}[/tex]
[tex]t=6years[/tex]
It will take 6 years for 7500 grams of X to reach 6900 grams.

A square of side 72 cm and a rectangle of length 90 cm have same perimeter. Find the difference in areas ?
A)216cm2
B)304cm2
C)324cm2
D)328cm2
Answer:
324 cm²
Step-by-step explanation:
→ Work out perimeter of square
72 + 72 + 72 + 72 = 288
→ Work out the width of the rectangle
288 - (90 × 2) = 108
108 ÷ 2 = 54
→ Work out area of square
72 × 72 = 5184 cm²
→ Work out area of rectangle
90 × 54 = 4860 cm²
→ Minus the areas from each other
5184 cm² - 4860 cm² = 324 cm²
Answer:
C) 324cm²
Step-by-step explanation:
1) they have the same perimeter so to find it you add all four sides of the square because they are all the same ( 72+72+72+72=288)
2) now you multiply 90 by 2 because the rectanglehas to sides of the same length(90×2=180) the answer you get you are going to subtract to 288 (288-180=108)
3) now divide 108 by 2 (108÷2= 54) the answer you get equals the width of the side of the rectangle
4) to get the area of the rectangle you multiply 54 with 90 (54×90=4,860) to get the area of the square you multiply 72 times 72 (72×72=5,184)
5) now you subtract 5,184 and 4,860 ( 5,184-4,860= 324cm²)
Two glasses contain orange juice.
A 400ml glass is 40% full.
A 300ml glass is half full.
Which glass contains less orange juice?
Plz give explanation too
Step-by-step explanation:
Amount of orange juice in 400ml glass
= 400ml * (40%/100%) = 160ml.
Amount of orange juice in 300ml glass
= 300ml * (1/2) = 150ml.
Since 150ml < 160ml, the 300ml glass contains less orange juice.
The second glass has less amount of orange juice.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Two glasses contain orange juice.
⇒ A 400ml glass is 40% full.
⇒ A 300ml glass is half full.
Now,
Since, Two glasses contain orange juice.
A 400ml glass is 40% full.
A 300ml glass is half full.
Hence, The amount of juice in first glass is,
⇒ 40% of 400
⇒ 40/100 × 400
⇒ 160 ml
And, The amount of juice in second glass is,
⇒ 300 / 2
⇒ 150 ml
Hence, The second glass has less amount of orange juice.

The radius of a circle is 1 foot. What is the area of a sector bounded by a 90 degree arc?
Answer:
The answer is 11/14 ft^2 or pi/4 ft^2
Step-by-step explanation:
The area of the sector bounded by that angle measure will be the area of the circle divided by 4
Area of the circle is;
pi * r^2
so the area here is;
22/7 * 1 * 1 = 22/7
divide this by 4
= 22/28 = 11/14 ft^2
Can someone help me with this please
Answer:
Step-by-step explanation:
4) the first thing to notice is that the sides a and c are the same.. that's what the small marks are telling you... that are the same length. and since they are.. this is an isosceles triangle and the two angle at the base .. along the b side will be the same.. so solving y is just the same as A or 52°
then to solve for x we also need to use that the triangle add up to 180° on those inside angles..
180= 52+52+14x+6
maybe you can solve it from here.. but i'll do it quickly
70 = 14x
5=x
5) the exterior angle at C is 146 the total angle is 180 so the angle inside the triangle is 180=146+x x= 34°
then use that the interior of the triangle add up to 180 again
180 = 34 + 5y+3 + 4y + 8
180 = 45 +9y
135 =9y
15 = y

PLEASE ANSWER QUICK!!! The volume of ammonia in a balloon is now 6.1 L after changing the temperature from 52 °C to 79 °C. What was the original volume?
Answer:
the original volume is 4.0L
Step-by-step explanation:
Step one:
given data
V1= ?
T1= 52 °C
V2= 6.1L
T2= 79° C
Step two
applying the volume temperature relationship, which is
V1/T1= V2/T2
substituting we have
V1/52= 6.1/79
cross multiply we have
52*6.1= V1*79
317.2= 79V1
divide both sides by 79
V1= 317.2/79
V1=4.0L
