Answer:
40
Step-by-step explanation:
Given :
10 ipil-ipil seedling to 3 Narra seedling
x ipil-ipil seedling for 12 Narra seedling
Using cross multiplication :
10 = 3
x = 12
Cross multiply
3 * x = 10 * 12
3x = 120
Divide both sides by 3
3x / 3 = 120 / 3
x = 40
Hence we have
40 ipil-ipil seedling to 12 Marra seedling
A rectangular pyramid. The rectangular base has a length of 10 inches and a width of 6 inches. 2 triangular sides have a base of 10 inches and height of 5.6 inches. 2 triangular sides have a base of 5 inches and height of 7.1 inches.
Answer:
Answer:
a) The base of the rectangular pyramid shown has an area of
60 square inches
b) A triangular face with a base of 10 inches has an area of 28 square inches.
c) A triangular face with a base of 5 inches has an area of 17.75 square inches.
d) The total surface area of the pyramid is 151.5 square inches.
Step-by-step explanation:
a) Solving for question a, we were given the following parameters
A rectangular pyramid. The rectangular base has a length of 10 inches and a width of 6 inches
The formula used to calculate the rectangular base of a rectangular pyramid =
Length × Width
Where :
Length = 10 inches
Width = 6 inches
Rectangular base = 10 inches × 6 inches
= 60 inches²
Hence, the base of the rectangular pyramid shown has an area of 60 square inches
b) Solving for question b, we have the following values given:
2 triangular sides have a base of 10 inches and height of 5.6 inches.
First step would be to solve for one triangular side first.
The area of the one triangular side = (Base × Height) ÷ 2
= (10 inches × 5.6 inches) ÷ 2
= 56inches² ÷ 2
= 28 inches²
Therefore, for the 2 triangular sides, since they have the same base and height, the other side as well would be 28 inches².
A triangular face with a base of 10 inches has an area of 28 square inches.
c) Solving for question c, the following parameters are given:
2 triangular sides have a base of 5 inches and height of 7.1 inches.
We would be to solving for one triangular side first.
The area of the one triangular side = (Base × Height) ÷ 2
= (5 inches × 7.1 inches) ÷ 2
= 35.5 inches² ÷ 2
= 17.75 inches²
Therefore, for the 2 triangular sides, since they have the same base and height, the other side as well would be 17.75 inches².
A triangular face with a base of 5 inches has an area of 17.75 square inches.
d) Solving for d, it is important to note that, a rectangular pyramid has 5 faces and they are: The rectangular base and 4 triangular faces
The formula for the total surface area of the rectangular pyramid is given as
Total Surface Area of the rectangular pyramid = Rectangular Base + Area of Triangular Side A + Area of Triangular Side B + Area of Triangular Side C + Area of Triangular Side D + Area of Triangular Side E
Total Surface Area of the Rectangular Pyramid = 60 inches² + 28 inches² + 28 inches² + 17.75 inches² + 17.75 inches²
Total surface Area of the Rectangular pyramid = 151.5 inches²
The total surface area of the pyramid is 151.5 square inches.

Paloma averaged a time of 2.3 minutes in each lap of a race. Marissa averaged 2.75 minutes in each lap. There were a total of 4 laps in the race. How many minutes ahead of Marissa did Paloma finish the race?
Poloma
2m30sec + 2m30sec + 2m30sec = 7m30sec
Marissa
2m75sec + 2m75sec + 2m75sec = 9m45sec
9m45sec - 7m30sec
Answer = 2m15sec
how many solutions does the graph above show?
a. one
b. none
c. infinite
Answer:
infinite
Step-by-step explanation:
The line can be represented by the equation y=-2/3x-2 since there are no other lines it would be infinite. if there was a line with the same slope and a different y-intercept the answer would be none as the lines never intersect. for the equation there are ifinitly many!
for example any point that that lone touches is a solutions so there is not one but many answers.

What is the expected average of rolling a single die
Answer:
Mathwords: Expected Value. A quantity equal to the average result of an experiment after a large number of trials. For example, if a fair 6-sided die is rolled, the expected value of the number rolled is 3.5. This is a correct interpretation even though it is impossible to roll a 3.5 on a 6-sided die.
Step-by-step explanation:
hope it helps
Answer:
When you roll a fair die you have an equal chance of getting each of the six numbers 1 to 6. The expected value of your die roll, however, is 3.5.

I really really need help with this and no one is answering. I've looked everywhere for how to do this and I fell like its simple but I can't find it. given -2+4i, express the complex number in polar form. I know the answer is 2 root 5(cos2.03 + isin2.03), but I don't know where the 2.03 comes from. Can someone explain please?
Result:
Complex number:
The polar form of z is:
Explanation:
z = −2 + 4i
z = 4.4721 · (cos 117o + i · sin 117o)
The polar form of the complex number z = a + bi is:
z = r · (cos θ + i · sin θ)
where, r is the modulus of z and θ is an argument of z. The moduo for a = −2 and b = 4 is:
r = a2 + b2 = · · · = 4.4721 To find argument θ we use one of the following formulas:
b θ=arctan a ifa>0
b o θ=arctan a +180 ifa<0
θ=90o ifa=0andb>0 θ=270o ifa=0andb<0
Inthisexample: a=−2andb=4so:
θ=arctan a +180
θ=arctan 4 +180o −2
b o
θ = arctan (−2) + 180o θ ≈ 117o

arctan(b/a)=arctan(4/-2)=-1.071
Because this falls in quardant 2, you have to add pi

−7x − 2y = −13
x − 2y = 11
use the substitution method to find x and y
Answer:
x=3
y=−4
Step-by-step explanation:
Add 2y to both sides of the equation.
x=11+2y
−7x−2y=−13
Replace all occurrences of x with 11+2y in each equation.
−77−16y=−13
x=11+2y
and then you just connect the dots

is it true that the sum of two repeating decimal is always repeating decimal
Answer:
no. it isn't necessary.
Step-by-step explanation:
there are some cases where adding two repeating decimals results in a sum which does not have a repeating decimal. For example,
1 over 3
+
2 over 3
=
3 over 3
=1
. Thus, the sum of two repeating decimals is not always a repeating decimal.

Answer:
y-intercept is (0, -2) and asymptote of y = -2.5
Step-by-step explanation:
If you substitute 0 in for x and simplify, then you will have the y-intercept
y = [tex]\frac{1}{2} (7)^{0} - 2.5 = \frac{1}{2} (1) - 2.5 = \frac{1}{2} - 2.5 = -2[/tex]
The y-intercept is (0, -2)
If the -2.5 were not there, then the graph would have an asymptote at y = 0 or the x-axis
The -2.5 moves the graph down 2.5 units so that y = -2.5 is the asymptote
Therefore, the first answer is correct

Tom makes a scale drawing of a statue using the scale 1 cm: 5 ft. His drawing measures 16 cm. Mary makes a scale drawing of the same statue, but uses the scale 1 cm: 4 ft. How many centimeters tall is the statue on Mary's drawing?
Answer:
20 cm
Step-by-step explanation:
1 cm of Tom's drawing is 5 ft of the statue
So his 16 cm drawing is [tex]16\times 5=80\ \text{ft}[/tex]
1 cm of Mary's drawing is 4 ft of the statue
1 ft of the statue is [tex]\dfrac{1}{4}\ \text{cm}[/tex] of the drawing.
So, 80 feet of the statue is [tex]80\times \dfrac{1}{4}=20\ \text{cm}[/tex] of the drawing.
Hence, Mary's drawing is 20 cm tall.
