Your family bought 4 sandwiches and 3 salads. Spending $24. Let x be the cost of a sandwich and y be the cost of a salad. What are the possible prices of the sandwiches and salads?
Answer:
x = 3
And, y = 4
Step-by-step explanation:
x = 3
y = 4
The computation of the possible prices of the sandwiches and salads is shown below:
Let us assume the x be the cost of the sandwich
And, the y be the cost of the salad
Now
4x + 3y = $24
Here we assume x = 3
y = 4
So
4(3) + 3(4) = $24
12 + 12 = 24
$24 = $24

Applying the cosine ratio, the value of x to the nearest tenth is: 11.9.
What is the Cosine Ratio?The cosine ratio is found using the formula, cos ∅ = adjacent length / hypotenuse length of a right triangle.
Given the following:
∅ = 32°Hypotenuse = 14Adjacent = xPlug in the values into the cosine ratio:
cos 32 = x/14
x = (cos 32)(14)

Divide £208 in the ratio 3:1
How do I do this??
Answer:
s = r1 s = 3.1 s = 3.1
or
v =a/s
v = 208/3.1
v = 67.0968
Step-by-step explanation:
The first part of the ratio would be 156. The second part of the ratio would be 52.
What is Ratio?A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other
To divide £208 in the ratio 3:1, you can use the following method:
Convert the ratio to a fraction by dividing the first number by the sum of the numbers in the ratio (3 / (3+1) = 3/4)
Multiply the fraction by the total amount you want to divide (£208)
The result will be the amount for the first part of the ratio, and the remaining amount is the second part of the ratio.
So the first part of the ratio would be: 3/4 × 208 = 156
The second part of the ratio would be: 208 - 156 = 52

you are selling pandesal to raise money for a school field trip. Pandesal with cheese cost 8.00 pesos and ube pandesal cost 9.00 pesos You need to sell at least two of each kind. You want to sell at least 180 pesos worth of pandesal. Write and graph a system of linear inequalities that represent the information given above
Answer:
Let's define:
C = number of pandesal with cheese that you sell
U = number of pandesal with ube that you sell.
If you sell these numbers of each, the total profit you get is:
C*8.00 pesos + U*9.00 pesos.
And yo want to get at least 180 pesos, then:
C*8.00 pesos + U*9.00 pesos ≥ 180 pesos.
And you also want to sell two of each, then:
C ≥ 2
U ≥2
So the system of inequalities is:
C*8.00 pesos + U*9.00 pesos ≥ 180 pesos.
C ≥ 2
U ≥2
If U is on the x-axis, and C is on the y-axis, then the graph is: (where the region at the right of the vertical line should be shaded)
Plotting the inequalities above using geogebra online graphing tool.
Let x represent the number of pandesal with cheese and y represent the number of ube with cheese
Since at least two of each kind is needed to be sold, hence:
x > 2, y > 2
At least 180 pesos worth of pandesal is needed to be sold, hence:
8x + 9y > 180

If a line has a slope of 3/5, and you have chosen two points on the line that have a rise of 15, what is the run?
Answer:
The run is 25
Step-by-step explanation:
Mathematically, the slope of an equation is;
Slope = change in y/change in x
change in y is called the rise, change in x is called the run
slope = rise/run
3/5 = 15/run
run = 15 * 5/3
run = 25

A random sample of CO2 levels in a school has a sample mean of x¯=598.4 ppm and sample standard deviation of s=86.7 ppm. Use the Empirical Rule to determine the approximate percentage of CO2 levels that lie between 338.3 and 858.5 ppm. Round your answer to the nearest tenth.
Answer:
99.7%
Step-by-step explanation:
we start by getting the z-scores for the values given
We can get the z-scores using the formula below;
z-scores = (x-mean)/SD
for 338.5;
z = (338.5-598.4)/86.7 = -2.99 approximately-3
for 858.5;
z = (858.5-598.4)/86.7 = 3
so we want to get the percentages that lie within 3 standard deviations from the mean
According to the empirical rule, the percentages within 3 SD of the mean is;
100-0.15-0.15 = 99.7%

Oliver invested $56,000 in an account paying an interest rate of 7 1 4 7 4 1 % compounded monthly. After 13 years, how much more money would Jocelyn have in her account than Oliver, to the nearest dollar?
Answer:
$4,205
Step-by-step explanation:
Jocelyn
A = p × e^rt
Where,
P = principal = $56000
e = Napier's number = 2.7283
r = interest rate = 7 3/8% = 0.07375
t = time = 13 years
A = 56,000 × 2.7283^(0.07375×13)
= 56,000 × 2.7283^0.95875
= 56,000 × 2.6177
= 146,591.2
Approximately
A = $146,591 to the nearest dollar
Oliver
A = p(1 + r/n)^nt
= 56,000(1 + 0.0725/12)^12*13
= 56,000(1 + 0.0060)^156
= 56,000(1.0060)^156
= 56,000(2.5426)
= 142,385.6
Approximately
A = $142,386 to the nearest dollar

3(x+4)=6x solve for x
Answer:
x = 4
Step-by-step explanation:
(First write the equation down)
3 ( x + 4 ) = 6x
(Then use the disstributive property)
3 times x and 3 times 4
3x + 12 = 6x
(Now subtract the same values aka 3x from both sides)
3x - 3x cancels out aka is 0
6x - 3x is 3x
(You now have...)
12 = 3x
(Now you divide both sides by 3)
12/ 3 = 3x/3
12 divided by 3 is 4
the two 3s cancel out leaving you with x
(You now have your answer)
4 = x
(Write it in proper format)
x = 4

A dilation has center (0,0). Find the image of the point L(-4,0) for the scale factor 9.
Dg (L=L(Type an ordered pair. Simplify your answer.)
Answer:
L' = (-36, 0)
Step-by-step explanation:
If the point (x, y) is dilated by a scale factor of k about the center (0, 0), then its image is the point (kx, ky)
∵ A dilation has a center (0, 0)
∵ The point L is (-4, 0)
∴ x = -4 and y = 0
∵ The scale factor of dilation is 9
∴ k = 9
→ By using the rule above
∵ kx = 9(-4) = -36
∵ ky = 9(0) = 0
∵ The image of the point L is (kx, ky)
∴ L' = (kx, ky)
∴ L' = (-36, 0)
