Answer:
correct answer is b) irrational number
Step-by-step explanation:
Rational number:
Any number which can be expressed in the form of fraction of two integers a/b, denominator b should be non zero. Every integer is a rational number.
irrational number:
Any number which cannot be expressed in the form of fraction of two integers a/b is known as irrational number.
square roots of numbers which are not perfect squares are irrational numbers. Only the square roots of perfect square numbers are rational.

For the spring festival, the Math Club is selling rulers for $1 and compasses for $2.50. the club would like to sell as many items as they can to raise funds. they need to at least make $15 to break even. write an inequality to represent this situation. let r=#of rulers sold and c=#of compasses sold.... School rules state that the club can sell a maximum of items for the festival. Write another inequality for this constraint (limitation).
Final answer:
To represent the situation, the inequality is 1r + 2.50c >= 15. The constraint on the maximum number of items sold is r + c <= M.
Explanation:
To write an inequality representing the situation, we need to consider the cost and the number of items sold. Let's denote the number of rulers sold as r and the number of compasses sold as c. The cost of the rulers is $1 each and the cost of the compasses is $2.50 each. The Math Club needs to make at least $15 to break even, so the inequality is: 1r + 2.50c >= 15.
Now, let's consider the constraint or limitation on the maximum number of items sold. Let's assume the maximum number of items that can be sold is M. So the inequality for this constraint is: r + c <= M.
Final answer:
The student should write the inequality 1r + 2.5c ≥ 15 to represent the condition of making at least $15 from selling rulers and compasses. An additional constraint can be represented by the inequality r + c ≤ m, with m being the maximum number of items allowed to be sold.
Explanation:
The Math Club is looking to make at least $15 by selling rulers at $1 each and compasses at $2.50 each. To represent this situation as an inequality where r is the number of rulers and c is the number of compasses sold, we use the equation: 1r + 2.5c ≥ 15. This inequality ensures that the combination of rulers and compasses sold will bring in at least $15.
If there is a maximum number of items that the Math Club is allowed to sell, we can represent this as another inequality. Let's say the maximum number of items is m. Then, we can write the inequality as: r + c ≤ m, where m is the given maximum number of items that can be sold.

Which triangles are congruent by ASA
Answer: ΔHGF≅ ΔABC
Step-by-step explanation:
ASA congruence postulate says that if two angles and the included side of a triangle are congruent to two angles and the included side of next triangle then the triangles are congruent.In the given figure ΔABC and ΔHGF have the pair of two corresponding angles and the included sides are congruent.
i.e.[tex]\angle{C}\cong\angle{F}[/tex]
[tex]\overline{GF}\cong\overline{BC}[/tex]
tex]\angle{G}\cong\angle{B}[/tex]
Therefore , by ASA congruence postulate:-
ΔABC ≅ ΔHGF
In ΔTUV , there is only angle given . So there is no enough information to prove it by ASA.

whats the answer to this question
the measures of two complementary angles have a ratio of 2:7 . what is the measure of the smaller angle
Answer:
The smaller angle is 20 degrees.
Explanation:
Complementary angles are two angles (or more) whose sum is 90 degrees.
If two angles have a sum of 90 degrees and their ratio is 2:7, we must determine which two numbers when added together would yield this proportion?
60 + 30 = 90 but 60:30 is a 6:3 ratio which simplifies to 2:1.
45 + 45 = 90 but 45:45 is a 1:1 ratio.
50:40 = 90 but 50:40 is a 5:4 ratio.
10 + 80 = 90, but 10:80 is a 1:8 ratio. We're getting closer!
20 + 70 = 90, and 20:70 can be simplified to 2:7 when you divide each number in the ratio their greatest common factor (GCF) of 10.
Therefore, the two complementary angles would be 20° and 70°, the smaller of which would be 20°

In order to make a servings for four 1 3/4 cups of chopped vegetables are needed based on this information determine the amount of chopped vegetables needed to make a recipe for ten
Answer:
To make recipe for 10 requires 35/8 or 4.375 chopped vegetables
Step-by-step explanation:
For 4, 7/4 cups of chopped vegetable are needed
it means for recipe for 4, requires 1.75 chopped vegetable
Therefore 10 recipe will require
10 × 7/4(1.75) cup divided by 4
Mathematically,
10 × 1.75 = 17.5
17.5/4 = 4.375 or 35/8 chopped

Rewrite this logarithm as a subtraction of logs
Log11 (29/11)
Final answer:
To rewrite the given logarithm as a subtraction of logs, use the property that the logarithm of the number resulting from the division of two numbers is the difference between the logarithms of the two numbers.
Explanation:
The given logarithm is log11 (29/11). To rewrite this as a subtraction of logs, we can use the property that the logarithm of the number resulting from the division of two numbers is the difference between the logarithms of the two numbers.
So, log11 (29/11) can be rewritten as log11 (29) - log11 (11).

What is the height of a rectangular prism that has a volume of 192 cubic feet and a base with an area of 48 square feet? Explain your work.
The height of the rectangular prism is 4 feet.
To find the height of the rectangular prism, we can use the formula for the volume of a rectangular prism, which is given by:
[tex]\[ \text{Volume} = \text{Base Area} \times \text{Height} \][/tex]
Given that the volume of the rectangular prism is 192 cubic feet and the base area is 48 square feet, we can set up the equation as follows:
[tex]\[ 192 = 48 \times \text{Height} \][/tex]
To solve for the height, we divide both sides of the equation by the base area:
[tex]\[ \text{Height} = \frac{192}{48} \][/tex]
[tex]\[ \text{Height} = 4 \][/tex]
Therefore, the height of the rectangular prism is 4 feet.

4.5 divided by 0.5+0.1 in computation words
Explanation of dividing 4.5 by 0.5+0.1 in computation words.
4.5 divided by 0.5+0.1 can be written as:
4.5 / (0.5 + 0.1)
To solve this, we first add 0.5 + 0.1 to get 0.6. Then, we divide 4.5 by 0.6 to find the result.
The result of the computation is 7.35.
To compute the given expression[tex]\(14.5 \times 0.5 + 0.1\):[/tex]
Multiplication :
- Multiply [tex]\(14.5\)[/tex] by [tex]\(0.5\).[/tex]
- [tex]\(0.5\)[/tex] represents half, so you're essentially halving 14.5.
Half of [tex]\(14.5\) is \(7.25\).[/tex]
Addition :
- Now add [tex]\(0.1\) to \(7.25\).[/tex]
- The addition gives [tex]\(7.25 + 0.1 = 7.35.[/tex]
Thus, the result of the computation is 7.35.

“Suppose the equation h=-16t^2 + 35t models the altitude a football will reach t seconds after it is kicked. IS THE GIVEN VALUE POSSIBLE?”
A: h= 16 ft. B: h= 20ft.
The given value h=16 ft is possible based on the quadratic equation model provided. By solving the equation h=[tex]-16t^2 + 35t[/tex] and substituting h=16, we find the possible values of t to be approximately 0.52 seconds or 1.48 seconds.
- For each given value of h, set [tex]\( h = -16t^2 + 35t \)[/tex] and solve for t.
- If you obtain real solutions, the given h is possible. If not, it isn't possible.
Checking for h=16:
1. Set h=16 and solve for t:
[tex]\[ 16 = -16t^2 + 35t \][/tex]
2. Rearrange to form a quadratic equation:
[tex]\[ -16t^2 + 35t - 16 = 0 \][/tex]
3. Solve for \( t \) using the quadratic formula:
[tex]\[ t = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \][/tex]
where a= -16, b=35, c=16.
- Find the discriminant:
[tex]\[ b^2 - 4ac = 35^2 - 4 \times (-16) \times (-16) = 1225 - 1024 = 201 \][/tex]
Since the discriminant is positive, this quadratic has real roots, indicating that h=16 is possible.
Checking for h=20:
1. Set h=20 and solve for t:
[tex]\[ 20 = -16t^2 + 35t \][/tex]
2. Rearrange to form a quadratic equation:
[tex]\[ -16t^2 + 35t - 20 = 0 \][/tex]
3. Solve for t using the quadratic formula:
[tex]\[ t = \frac{-35 \pm \sqrt{35^2 - 4 \times (-16) \times (-20)}}{2 \times (-16)} \][/tex]
- Find the discriminant:
[tex]\[ 35^2 - 4 \times (-16) \times (-20) = 1225 - 1280 = -55 \][/tex]
Since the discriminant is negative, this quadratic has no real roots, indicating that h=20 is not possible.
Conclusion:
- The value h=16 is possible.
- The value h=20 is not possible.
