The Jordan family budgeted 16% of their disposable annual income of $44,000 for food, but found they needed $35 more per week. How much of their income should now be added to their food budget?
$1,587. 00
$1,820. 00
$1,924. 00
$2,042. 00
None of these choices are correct
Multiplication is the process of multiplying two numbers. The amount that is needed to be added to the income is $1,820.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that Jordan's family needs to add $35 more per week to their food budget, Since a year has 52 weeks, therefore, the amount that is needed to be added by Jordan's family is,
[tex]\rm Amount\ Needed = \$35 \times 52 = \$1,820.00[/tex]
Hence, the amount that is needed to be added to the income is $1,820.

Reflect triangle ABC over the line x= -3.
What are the new coordinates?
Answer:
Step-by-step explanation:
We do not know the coordinates of triangle ABC, however, if the coordinates were (hypothetially) A (-2,0) B (-2,2) and C (-1,0) then we would flip triangle ABC over the line x=-3, point A would move 2 points horizontally to the left. Point B would move 2 points horizontally to the left. Point C, would move 4 points horizontally to the left. The Y coordinates would stay the same. Basically, instead of flipping it over the origin, you "move the origin" to whichever point you are told, they would function the same.
There are 40 students in a class and 95% of these students passed their Chemistry text. What number of these students passed their test? Round you answer to the nearest whole number if necessary.
(Please answer, I will mark brainliest!)
Answer: 38 students
Step-by-step explanation:
To answer this question we will find 95% of 40. Keep in mind that a percent divided by 100 becomes a decimal.
95% / 100 = 0.95
0.95 * 40 = 38
38 students passed their test.

Besides the 90° angle measure, what are the other two angle measures of a right triangle with side lengths 5, 12, and 13? Round to the nearest degree.
18° and 39°
23° and 67°
43° and 47°
65° and 25°
Answer:
B
Step-by-step explanation:
Remark
The angle opposite the hypotenuse is 90 degrees. The hypotenuse is 13 in this case and is labeled c.
The second longest line is opposite the second largest angle
Sin(A) = opposite / hypotenuse
Solution
Sin(A) = 12 / 13 = Opposite / hypotentenuse
opposite = 12 12 is the second longest linehypotenuse = 13Sin(A) = 0.9231 12/13 = 0.9231
A = sin-1(0.9231) Take the inverse sine of 0.9231
A = 67 rounded
Therefore then angle opposite the shortest side must be 90 - 67 = 23
Answer: 67 and 23

Businesses are not to discriminate against their workers based on their nation of origin, but can discriminate based on age.
What is Age Discrimination for a Job ?Discrimination can simply be defined as favoring one person over another based on certain criteria or biases.
In almost all businesses, the law stipulates that certain criteria such as nation of orgin, race, disability among others should not be used against an indivdual. However, for age, certain age limit are permitted to be used by businesses to select employees.
Therefore, all business can discriminate against a worker using age.

The quadratic equation has no real roots. This means the line and point has no point of intersection.
System of equationsSystem of equations are equations that is more than one and have two or more unknowns.
Given the simultaneous equation

from equation 2;
y = 25 - 2x ................3
Substitute equation 3 into 1 to have:
x^2 + (25-2x)^2 = 25

Answer:
[tex]1609.1 m^{3}[/tex]
Step-by-step explanation:
The area of a triangle is 1/2 base * height.
The base of one side is 13, and the height is 30.
30 * 13 = 390
390 / 2 = 195
Now, there are six of these triangle faces, so multiply that number by six.
195 * 6 = 1170
Now, just add the area of the base:
1170 + 439.1 = 1609.1

Hi!
Your answer is 52.
To start off, let's start with some facts that will help us solve this:
Supplementary angles are two angles whose angle measures add up to 180 degrees. You can know that they are supplementary because they can be connected by a straight line.
Triangles (all of them) have angles that add up to 180 degrees.
We can start by using supplementary angles to solve. See where the angle of 67 degrees is? The one to the right of it is supplementary to it since they are on a straight line. That means their sum adds up to 180 degrees:
[tex]67 +?=180[/tex]
[tex]?=113[/tex]
That angle is 113 degrees.
Now, we have 2 out of 3 angles in the triangle. Since we know that triangles' angles add up to 180 degrees, we can make an equation:
[tex]15+113+x=180[/tex]
[tex]128+x=180[/tex]
[tex]x=52[/tex]
Therefore, x is equal to 52.

Members of a student council are designing a school float for a parade. They decide to poll 10% of the student body to get feedback about the theme they have chosen. What would most likely happen if they decided to randomly sample 5% of the student body instead? A. The sample proportion would less closely model the population proportion. B. The sample proportion would more closely model the population proportion. C. The sample proportion would not be affected. D. There is not enough information to determine how the sample proportion would be affected.
Answer:
B. The sample proportion would less closely model the population proportion.
Step-by-step explanation:
if they chose 10% and changed it to 5% theres gonna be less data to go by.
The sample proportion would less closely model the population proportion.
Option A is the correct answer.
What is random sampling?Random sampling is a statistical method of selecting a sample from a larger population in a way that every individual in the population has an equal chance of being selected.
In other words, random sampling is a process of selecting a subset of individuals from a population in which every member of the population has an equal chance of being chosen.
This helps to reduce bias and increase the likelihood that the sample represents the population accurately.
Random sampling is commonly used in research studies, opinion polls, and market research to draw conclusions about a population based on a smaller sample.
We have,
When the sample size is smaller, there is a higher chance of the sample being unrepresentative of the population, resulting in a larger sampling error.
Therefore, if the student council decided to sample only 5% of the student body instead of 10%, it is more likely that the sample proportion would be less accurate and less closely model the population proportion.
Thus,
The sample proportion would less closely model the population proportion.

From a circular cylinder of diameter 10 cm and height 12 cm are conical cavity of the same base radius and of the same height is hollowed out. Find the volume and the whole surface of the remaining solid.
[tex](take \ \: \pi \: = 3.14) [/tex]
Step-by-step explanation:
Now, Given that:-
Diameter (d) = 10 cm
So, Radius (r) = 10/2 = 5cm
Height of the cylinder = 12cm.
[tex]volume \: of \: the \: cylinder \: = \pi {r}^{2} h[/tex]
[tex] = > \pi \times {5}^{2} \times 12 {cm}^{3} = 300\pi {cm}^{3} [/tex]
Radius of the cone = 5 cm.
Height of the cone = 12 cm.
[tex]slant \: height \: of \: the \: cone \: = \sqrt{ {h}^{2} + \: {r}^{2} } [/tex]
[tex] = > \sqrt{ {5}^{2}+{12}^{2} } cm \: = 13cm[/tex]
Volume of the cone = 1/3 *πr^2h
[tex] = > \frac{1}{3} \pi \times {5}^{2} \times 12 {cm}^{3} = 100\pi {cm}^{3} [/tex]
therefore, the volume of the remaining solid
[tex] = 300\pi {cm}^{3} - 100\pi {cm}^{3} \\ = 200 \times 3.14 {cm}^{3} = 628 {cm}^{3} [/tex]
Curved surface of the cylinder =
[tex]2\pi \: rh \: = 2\pi \times 5 \times 12 {cm}^{2} \\ = 120\pi {cm}^{2} .[/tex]
[tex]curved \: surface \: of \: the \: cone \: = \pi \: rl \\ = \pi \times 5 \times 13 {cm}^{2} \\ = 65\pi {cm }^{2} \\ area \: of \: (upper)circular \: base \: \\ of \: cylinder \: = \\ = \pi \: {r}^{2} = \pi \times {5}^{2} [/tex]
therefore, The whole surface area of the remaining solid
= curved surface area of cylinder + curved surface area of cone + area of (upper) circular base of cylinder
[tex] = 120\pi {cm}^{2} + 65\pi {cm }^{2} + 25 \pi {cm}^{2} \\ = 210 \times 3.14 {cm}^{2} = 659.4 {cm}^{2} [/tex]

Answer:
(4, 2 ) and (2, 4 )
Step-by-step explanation:
xy = 8 → (1)
y = - x + 6 → (2)
substitute y = - x + 6 into (1)
x(- x + 6) = 8
- x² + 6x = 8 ( subtract 8 from both sides )
- x² + 6x - 8 = 0 ( multiply through by - 1 )
x² - 6x + 8 = 0 ← in standard form
(x - 4)(x - 2) = 0 ← in factored form
equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x - 2 = 0 ⇒ x = 2
substitute these values into (2) for corresponding values of y
x = 4 : y = - 4 + 6 = 2 ⇒ (4, 2 )
x = 2 : y = - 2 + 6 = 4 ⇒ (2, 4 )
