Mrs. Garcia's math test is worth 50 points. If you answer all the questions and the extra credit correctly, you can score 55 points. How do you represent this situation as a fraction, a decimal, and a percent?
Answer:
Divide the percentage by 100 to get a decimal number. Use that number as the numerator (top) of a fraction. Put a 1 in the denominator (bottom) of the fraction. Convert the decimal to a whole number: Count how many places are to the right of the decimal.
A housewife deposited Rs 10,000 on saving account at 5% p.a. interest compounded
yearly and another sum on fixed deposit account at 8% p.a. interest compounded
half yearly. After one year the interest on fixed deposit account
was Rs 152.80 more
than the interest on the saving account, find the total amount of money in her two
accounts at the end of the year.
Answer:
Rs. 3923.08
Step-by-step explanation:
First principal invested = Rs. 10000
Interest rate = 5%
The interest is compounded yearly.
Time = 1 year
1 year compound interest is equal to simple interest.
Formula for simple interest:
[tex]SI = \dfrac{PRT}{100}[/tex]
Interest on first sum = [tex]\frac{10000\times 5\times 1}{100} = Rs\ 500[/tex]
Another sum is on fixed deposit 8% compounded half yearly.
Let the sum = Rs [tex]x[/tex]
Formula for compound interest is given as:
[tex]CI = P(1+\frac{R}{100})^T - P[/tex]
It is compounded half - yearly, therefore T = 2
[tex]CI = x (1+\frac{8}{100})^2 - x\\\Rightarrow CI = x(1.08)^2-x = 0.1664x[/tex]
As per question statement:
[tex]0.1664x - 500 = 152.80\\\Rightarrow x = \dfrac{652.80}{0.1664} = Rs\ 3823.08[/tex]

38 quart per hour
23 quart per hour
34 quart per hour
32 quarts per hour
Answer:
1 1/2 quarts per hour

Step-by-step explanation:
A box of granola weighs 24 ounces and a box of bran flacks weighs 6/8 as much as the ronal A box of Corn Pops weighs 1 1/8 as much as the ronal what is the least number of ounces found in either box or ronal bran flakes or Corn Pops
Answer:
54 ounces
Step-by-step explanation:
A box of granola weighs 24 ounces and a box of bran flacks weighs 6/8 as much as the ronal
The number of ounces of the bran flakes = 6/8 of the box of the granola
= 6/8 × 24 ounces
= 18 ounces
A box of Corn Pops weighs 1 1/8 as much as the granola
Hence, the number of ounces of the box of corn pops =
1 1/8 of the granola box
= 9/8 × 24 ounces
= 27 ounces
The least number of ounces found in either box or ronal bran flakes or Corn Pops is calculated as:
We solve using LCM Method
Multiples of 18:
18, 36, 54, 72, 90
Multiples of 27:
27, 54, 81, 108
Therefore,
LCM(18, 27) = 54
The least number of ounces found in either box or ronal bran flakes or Corn Pops is 54 ounces

Answer:
(a) The zeroes of f(x) are rational numbers
(b) The smallest integer value of a is 3
Step-by-step explanation:
In the quadratic function f(x) = ax² + bx + c, we can know the number and the types of its roots using the discriminant Δ, where Δ = b² - 4ac
If Δ > 0, then the zeroes are two different real numbersIf Δ = 0, then the zeroes are the same real numberIf Δ < 0, then the zeroes are imaginary numbersNote: In the first case if Δ is a perfect square number then the zeroes are rational, if not then the zeroes are irrational
(a)
∵ The equation function is f(x) = ax² + 11x + 12
∵ a = 2
∴ a = 2, b = 11 and c = 12
→ Substitute them in the rule of Δ
∵ Δ = (11)² - 4(2)(12) = 121 - 96
∴ Δ = 25
∵ Δ > 0
∴ f(x) has two different real zeroes
∵ 25 is a perfect square number
→ That means the zeroes of the function are rational numbers
∴ The zeroes of f(x) are rational numbers
(b)
∵ f(x) ha imaginary zeroes
→ By using the third rule above
∴ Δ < 0
∵ a = a, b = 11 and c = 12
→ Substitute them in the rule of Δ
∴ (11)² - 4(a)(12) < 0
∴ 121 - 48a < 0
→ Add 48a to both sides
∵ 121 - 48a + 48a < 0 + 48a
∴ 121 < 48a
→ Divide both sides by 48
∴ 2.52083 < a
∴ a > 2.52083
∵ The smallest integer greater than 2.52083 is 3
∴ The smallest integer value of a is 3

On a coordinate plane, triangles P Q R and S T U are shown. Triangle P Q R has points (4, 4), (negative 2, 0), (negative 2, 4). Triangle S T U has points (2, negative 4), (negative 1, negative 2), (negative 1, negative 4). Complete the statements to verify that the triangles are similar. StartFraction Q R Over T U EndFraction = StartFraction P R Over S U EndFraction = StartFraction P Q Over S T EndFraction = StartFraction StartRoot 52 EndRoot Over StartRoot 13 EndRoot EndFraction = Therefore, △PQR ~ △STU by the theorem.
Answer:
The answer is below
Step-by-step explanation:
Two triangles are said to be similar if their corresponding angles are equal and the corresponding sides are in proportion.
The distance between two points on the coordinate plane is given as:
[tex]Distance=\sqrt{(x_2-x_1}^2+(y_2-y_1)^2 \\\\Therefore\ in\ triangle\ PQR:\\\\|QR|=\sqrt{(-2-(-2))^2+(4-0)^2}=4\\\\|PQ|=\sqrt{(-2-4)^2+(0-4)^2}=\sqrt{52}=2\sqrt{13} \\\\|PR|=\sqrt{(-2-4)^2+(4-4)^2}=6[/tex]
In triangle STU:
[tex]|ST|=\sqrt{(-1-2)^2+(-2-(-4))^2}=\sqrt{13}\\\\|SU|=\sqrt{(-1-2)^2+(-4-(-4))^2} =3\\\\|TU|=\sqrt{(-1-(-1))^2+(-4-(-2))^2}=2[/tex]
|QR| / |TU| = 4/2 = 2
|PR| / |SU| = 6/3 = 2
|PQ| / |ST| = 2√13 / √13 = 2
Hence:
|QR| / |TU| = |PR| / |SU| = |PQ| / |ST|
Therefore, △PQR and △STU are similar triangles since the ratio of their sides are in the same proportion.
Similar triangles may or may not be congruent
Triangles PQR and STU are similar by SSS theorem.
The vertices of triangle PQR are given as:
[tex]P= (4, 4)[/tex]
[tex]Q= (-2, 0)[/tex]
[tex]R = (-2, 4)[/tex]
The vertices of triangle STU are given as:
[tex]S = (2, -4)[/tex]
[tex]T = (-1, -2)[/tex]
[tex]U =(-1, -4)[/tex]
Start by calculating the side lengths of the two triangles, using the following distance formula
[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]
For triangle PQR, we have:
[tex]PQ = \sqrt{(4 --2)^2 + (4 -0)^2} = \sqrt{52}[/tex]
[tex]PR = \sqrt{(4 --2)^2 + (4 -4)^2} = 6[/tex]
[tex]QR = \sqrt{(-2 --2)^2 + (0 -4)^2} = 4[/tex]
For triangle STU, we have:
[tex]ST= \sqrt{(2 --1)^2 + (-4 --2)^2} = \sqrt{13}[/tex]
[tex]SU= \sqrt{(2 --1)^2 + (-4 --4)^2} = 3[/tex]
[tex]TU= \sqrt{(-1 --1)^2 + (-2 --4)^2} = 2[/tex]
Check if the side lengths of both triangles are similar, by dividing corresponding sides
[tex]k = \frac{PQ}{ST} = \frac{\sqrt{52}}{\sqrt{13}} = 2[/tex]
[tex]k = \frac{PR}{SU} = \frac{6}{3} = 2[/tex]
[tex]k = \frac{QR}{TU} = \frac{4}{2} = 2[/tex]
Because the scale factors of the side lengths are the same, then both triangles are similar by SSS theorem.
