Answer:
198 hamburgers
Step-by-step explanation:
Because the additive inverse of multiplication is division and since the cheeseburger are three times the number of hamburgers you should divide by three to get how many hamburgers were sold. Hope this helps
Calculate the marked price of a sweater purchased at Rs. 1075 allowing 14% discount. ( please do proper answer )
Answer: $1225.50
Step-by-step explanation:
Purchase price = $1075
Discount Percent = 14%
Discount = 14% × $1075
= 0.14 × $1075
= $150.50
Marked price = Purchase price + Discount
= $1075 + $150.50
= $1225.50
Gracie is sharing 75 marshminnows among 4 of her friends. If each of her friends gets the same number of marshminnows, and she gives them as many marshminnows as
possible, how many are left for Gracie?
none
3
18
19
Answer:
18
Step-by-step explanation:
If you want to give people something, you need to divide the number that she is sharing (75) and the number of how many people she is sharing with (4).
So 75/4 = 18
So 18 marshminnows are left for Gracie.
The distance between two cities on a map is 3.5 centimeters. The map uses a scale in which 1 centimeter represents 20 kilometers. What is the actual distance between these two cities in kilometers?
Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value.
Answer:
70 km
Step-by-step explanation:
[tex]\frac{3.5 cm}{x km}[/tex] = [tex]\frac{1cm}{20km}[/tex]
x = (3.5 cm × 20 km) ÷ 1 cm = 70 km
Answer:
70 km

At a little-known vacation spot, taxi fares are a bargain. A 56-mile taxi ride takes 63 minutes and costs $50.40 You want to find the cost of a 34- taxi ride. What unit price do you need?
Answer:
the unit price that required is $30.60
Step-by-step explanation:
The computation of the unit price that required is shown below
For one mile, the cost is
= taxi ride cost ÷ distance covered
= $50.40 ÷ 56
= $0.90
Now for the cost of 34 mile taxi ride
= Unit cost × distance covered
= $0.90 × 34 mile
= $30.60
hence, the unit price that required is $30.60
We simply applied the above formula so that the correct cost could come
The same is to be considered

Answer:
First/Top graph.
Step-by-step explanation:
First, we need to solve the inequality for n:
-6n + 5 < 11 (Given)
-6n < 6 (Subtracted 5 on both sides)
n > -1 (Divided -6 on both sides)
NOTE: Whenever you multiply or divide by a negative number when dealing with inequalities, the sign switches.
Now that we know that n > -1, we need to look for a graph that has an open circle on the point -1 and goes in the right direction.
Therefore, the first graph is the correct answer.

A general arranges his students to form a perfect square.He finds that in doing so 60 soldiers were left out if total number of soldiers be 8160 find the number of soldiers in each row
Answer:
90
Step-by-step explanation:
Given that :
Number of soldiers = 8160
Number left out = 60
Result of arrangement gives a perfect square ;
Hence, the number of soldiers which makes up the arrangement will be ;
Total number of soldiers - number left out
8160 - 60 = 8100
Hence 8100 soldiers were used to form a perfect square ;
Number of soldiers in a row :
√8100 = 90
Hence, we have 90 soldiers in a row

A park has a 3m tall tetherball pole, and a 6.8m tall flagpole. The lengths of their shadows are proportional to their heights.
Complete question is;
A park has a 3 meter tall tether ball pole and a 6.8 m tall flagpole. The lengths of their shadows are proportional to their heights.
Which of the following could be the lengths of the shadows?
Choose 2 answers from the options attached.
Answer:
Options B & D
Step-by-step explanation:
From the question, the proportional relationship between the height and shadow length is a direct proportionality. This means that an increase in the height, leads to an increase in the length of shadow and vice versa. Thus, the height to shadow length ratio is a constant.
Now, if we use x and y to denote length of shadow of tether ball pole and length of flagpole receptively, we will have;
3/x = 6.8/y
Let's make y the subject.
y = 6.8x/3
Looking at the options;
Option A: When x = 1.35 m, we have;
y = (6.8 × 1.35)/3 = 3.06 m
For Option B:
When x = 1.8 m,
y= (6.8 × 1.8)/3 = 4.08 m
For Option C:
When x= 3.75 m,
y = (6.8 × 3.75)/3 = 8.5 m
For option D:
When x = 0.6
y = (6.8 × 0.6)/3 = 1.36 m
For option E;
When x = 2,
y = (6.8 × 2)/3 = 4.533 m
From our calculations, the only values of y that correspond with the given value of y in the options are Options B & D
Un camión admite en su interior 68,25 toneladas de patatas. Se cada caja de patatas pesa 22,75 Kg, ¿cuántas cajas de
patatas lleva el camión?
Answer:
El camión lleva 3000 cajas de patatas
Step-by-step explanation:
Proporciones
La capacidad de carga de un camión es de 68.25 Toneladas de patatas.
Como 1 tonelada es equivalente a 1000 Kg, expresamos la capacidad en Kg:
68.25 * 1000 = 68250 Kg
Cada caja de patatas pesa 22.75 Kg, luego el número de cajas que caben en el camión son:
68250/22.75 = 3000 cajas
El camión lleva 3000 cajas de patatas

Jose worked 8 days for a total of 58.4 hours. If he worked the same number of hours each day, how many hours did he work in a day?
Answer:
7.3 or 7 hours.
Step-by-step explanation:
So i divided 58.4 by 8. And got 7.3.
8 x (7) = 56. So, 58 - 56 = 2. Put the decimal up. Now, 8 x (3) = 24. So, now you should have 7.3. But you could round it to 7. Depends.

find the value of x in each of the given triangles.
Answer:
x= 12°
Step-by-step explanation:
The angle measures in the triangle are given as;
A = 4x
B= 5x
C= 6x
The sum of angle measures in a triangle add up to 180°
Applying the statement in an equation as;
4x + 5x + 6x = 180°
15x = 180°
x= 180° / 15
x = 12°

Answer:
[tex]T_n=(4-n)\text{log}_a(3)+\text{log}_a(2)[/tex]
Step-by-step explanation:
nth term of an A.P. is given by the explicit formula,
[tex]T_n=a+(n-1)d[/tex]
Here, 'a' = First term
n = number of term
d = common difference
For an A.P. given as,
[tex]\text{log}_a(54),\text{log}_a(18),\text{log}_a(6),....[/tex]
First term 'a' of the given A.P. = [tex]\text{log}_a(54),[/tex]
Common difference 'd' = [tex]T_2-T_1[/tex]
= [tex]\text{log}_a(18)-\text{log}_a(54)[/tex]
= [tex]\text{log}_a(\frac{18}{54})[/tex]
= [tex]\text{log}_a(\frac{1}{3})[/tex]
= [tex]-\text{log}_a(3)[/tex]
[tex]T_n=\text{log}_a(54)+(n-1)[-\text{log}_a(3)][/tex]
[tex]=\text{log}_a(54)-(n-1)\text{log}_a(3)[/tex]
[tex]=\text{log}_a(3^3\times 2)-(n-1)\text{log}_a(3)[/tex]
[tex]=\text{log}_a(3^3)+\text{log}_a(2)-(n-1)\text{log}_a(3)[/tex]
[tex]=3\text{log}_a(3)+\text{log}_a(2)-(n-1)\text{log}_a(3)[/tex]
[tex]=3\text{log}_a(3)+\text{log}_a(2)-n\text{log}_a(3)+\text{log}_a(3)[/tex]
[tex]=4\text{log}_a(3)+\text{log}_a(2)-n\text{log}_a(3)[/tex]

At the moment there are 54,210 tagged birds in a certain wildlife refuge. If exactly 20 percent of all birds in the refuge are tagged, what percent of the untagged birds must be tagged so that half of all birds in the refuge are tagged?
Answer:
37.5%
Step-by-step explanation:
OOF DIS COMPLICATED
I messed up big timeeeeeeeee
A lot of percent problem are very simple by just assuming values, especially in case the answer is also a percentage.
If there are 100 birds, 20% are tagged so 20 are tagged.
Out of the rest 80, 30 should be tagged so that a total of 50% are tagged.
30/80 = 37.5%
(The huge number given is unnecessary, just to make you waste your valuable time. Read the question again to realize that it is not needed.)
The percent of the untagged birds that must be tagged so that half of all birds in the refuge are tagged is 37.5%.
Untagged birds percentage:First step
Currently Tagged birds= 54210 ×20/100
Currently Tagged birds=10842
Second step
Untagged birds=54210 - 10842
Untagged birds=43368
Third step
Untagged birds percentage:
Untagged birds percentage=( 54210/2)-10842/43368
Untagged birds percentage=(27105-10842)/43368
Untagged birds percentage=16263/43368
Untagged birds percentage=0.375×100
Untagged birds percentage=37.5%
Inconclusion the percent of the untagged birds that must be tagged so that half of all birds in the refuge are tagged is 37.5%.

A ,B and C average is 45 ,b and C average is 40 then find b
This question is incomplete
Complete Question
The average weight of A, B and C is 45 kg. If the average weight of A and B be 40 kg and that of B and C be 43 kg, then the weight of B is :
Answer:
31 kg
Step-by-step explanation:
From the above question:
A ,B and C average is 45.
Hence, the total values of A, B, C is calculated as:
A + B + C /3 = 45
A + B + C = 45 × 3
A + B + C = 135
Also,
B and C average is 43
The total values of B, C is calculated as:
B + C /2 = 43
B + C = 43 × 2
B + C = 86
A and B average is 40
The total values of A, B is calculated as:
A + B /2 = 40
A + B = 40 × 2
A + B = 80
Hence:
A + B + C = 135
B + C = 86
A + B = 80
Hence, we can solve for A, we substitute 80 for A + B
80 + C = 135
C = 135 - 80
C = 55kg
B + C = 86
B + 55 = 86
B = 86 - 55
B = 31 kg
