120 sweets are put into three different size boxes.
The sweets are put into a small box, a medium box and a large box in the ratio 1:2:5
Work out the number of sweets in a large box.
Answer:
75 sweets
Step-by-step explanation:
Given that
There is 120 sweets that are put into three different size boxis
And, the ratio of small box to medium box to large box is 1:2:5
We need to find out the no of sweets in the large box
So,
The number of sweets in a large box is
= 120 sweets × 5 ÷ (1 + 2 + 5)
= 120 sweets × 5 ÷ 8
= 75 sweets

A. all real numbers
B. {-31, -29, -32}
C. {7, 1, -8}
D. {-5, 1, -8}
Answer:
Solution given:
f(x) = -3x + 1
f(-2)=-3×-2+1=7
f(0)=-3×0+1=1
f(3)=-3×-3+1=-8
So
Range is {7,1,-8) is a required answer
Find the area of the following rectangle. Type out al work
Step-by-step explanation:
[tex]area = length \times width \\ = (4x + 3) \times (2x + 2) \\ = ( {8x}^{2} + 8x + 6x + 6) \\ = ( {8x}^{2} + 14x + 6) \: {units}^{2} [/tex]
Answer:
[tex](8x + 14x + 6)^{2}[/tex]
Step-by-step explanation:
Area of a rectangle is length x breadth
In the given figure, the length is 2x + 2 and breadth is 4x + 3
So, the area would be:-
(2x + 2) (4x + 3)
[tex]8x^{2}[/tex] + 6x + 8x + 6
So the area would be => [tex](8x + 14x + 6)^{2}[/tex]

solve 2x+2y=-4, 6x-2y=12 using Elimination
NO LINKS (i need the steps not just the answer)
Answer:
2x+2y=-4
since we don't know the value of the letters, we could ignore it. then we add 2+2 which equals 4
6x-2y=12
In this case this equation is incorrect.
Step-by-step explanation:
sorry if I'm incorrect
(please if I'm correct, I really need the brainliest)
Answer:
(1,-3)
or
x=1 y= -3
Step-by-step explanation:
Looking at this we can see that there's a 2y in both of the equations (one is negative while the other is positive and so we'll add them)
so we have
(2x+2y)+(6x-2y)= -4+12
this simplifies to
8x=8
x=1
We know that x=1 and so we will plug this back into one of the two equations
2(1)+2y= -4
2+2y= -4
2y= -6
y= -3
Therefore the solution is (1,-3)

Lin says that the inequalities LaTeX: h>150h > 150 and LaTeX: h<160h < 160 describe her height in centimeters.
What do the inequalities tell us about her height?
Can you guys help me!!!!!!!
Answer:
Lin is between 150 and 160 cm
Step-by-step explanation:
The height is represented by the inequality :
h > 150 and h < 160
h > 150 - - (1)
h < 160 - - - (2)
Combining the two :
h > 150 means 150 is less than h but h is not upto 160
Thus, we have ;
150 < h < 160
This means height, h occurs between the range ; 150 cm and 160 cm

Seven gallons of a sugar solution was mixed with 4 gallons of a 80 percent sugar solution to make an 72 percent sugar solution. Find the percent concentration of the first solution. (a) 70% (b) 61% (c) 69% (d) 67%
Answer:
67%
Step-by-step explanation:
Let the percentage of the first solution = x
7 gallons + 4 gallons = 11 gallons
Our system of equation is
Seven gallons of a sugar solution was mixed with 4 gallons of a 80 percent sugar solution to make an 72 percent sugar solution.
7 gallons × x % + 4 gallons × 80% = 72% × 11 gallons
= 7x + 3.2 = 7.92
Collect like terms
7x = 7.92 - 3.2
7x = 4.72
x = 4.72/7
x = 0.6742857143
Converting to percentage
0.6742857143 × 100
= 67.42857143%
Approximately, the percent concentration of the first solution is 67%

A map of a highway has a scale of 2 inches equals 33 miles. The length of the highway on the map is 6 inches. There are 11 rest stops equally spaced on the highway, including one at each end. You are making a new map with a scale of 1 inch equals 30 miles. How far apart are the rest stops on the new map?
(nvm)
Answer:
The answer is "0.975"
Step-by-step explanation:
Please find the complete question in the attched file.
Find the remaining distance inside the original map
[tex]\to \frac{9}{6}=1.5 \ in[/tex]
Dividing the value by 6 because there are 7 rest stop:
[tex]\to \frac{2 \ inches}{39 \ inches} =\frac{1.5 \ inches}{x \ miles}\\\\\to x=39 \times \frac{1.5}{2}\\\\\to x=29.25 \ miles[/tex]
Finding the diatance of the rest stop in the new map
Using proportion:
[tex]\to \frac{1 \ inches}{30 \ miles} =\frac{x \ inches}{ 29.25 \ miles}\\\\\to x= \frac{29.25}{30}\\\\\to x=0.975 \ in[/tex]
What is the volume of this 3 dimensional figure
Answer: 2496in³

Answer:
3x - (15 x 3) = 90
or
3x - 45 = 90
Explanation:
There are 3 boxes. We don't know how many are in them yet, so we write this as 3x. However, we know that we give away 15 to 3 different teachers. 15 x 3 = 45
Therefore, the first part is 3x - 45
We also know that in the end we have 90 left.
So our final equation is:
3x - 45 = 90
1. Calculate the value of 8. 1 × 103 − 2. 4 × 102 in standard form.
2. Blood comprises 8% of the weight of a human. Amy weighs 40kg. Find the weight of her blood.
Step-by-step explanation:
1. We need to find the value of 8.1 × 10³ − 2.4 × 10² in standard form.
We can also write its as :
8.1 × 10³ − 2.4 × 10²
81000 − 240
Standard form = 80760
2.
Amy's weight = 40 kg
Blood comprises 8% of the weight of a human.
Weight of her blood,
[tex]W=8\%\ of\ 40\\\\=\dfrac{8}{100}\times 40\\\\=3.2\ kg[/tex]
So, the weight of her blood is equal to 3.2 kg.
triangle abc is similar to triangle fgh solve for x
Answer:
A= 24
Step-by-step explanation:
First find the scale factor. so the scale factor for these two triangles is 1.5.
21 / 14 = 1.5
18 / 12 = 1.5
So you are going to multiply 16 x 1.5
That will give you 24.

A jar has 28 cherry-flavored candies, 19 strawberry-flavored candies, 20-orange flavored candies, and 33 lemon-flavored candies. If a candy is taken from the jar at random, what is the probability that it will be a cherry-flavored cnady?
Answer: 7/25 or 28%
Step-by-step explanation:
28 (cherry) + 19 (strawberry) + 20 (orange) + 33 (lemon) = 100 (total)
so p(cherry), or the probability of getting cherry, is 28/100 (7/25)
that as a percent is 28%
