find the product of 3 and 3/4 and 1 1/10 how do you find the product and how did you come up with it could you show your work
Answers
3 3/4 = (3 × 4 + 3) / 4 = 15/4
1 1/10 = (1 × 10 + 1) / 10 = 11/10
Now, we find the receprical of the second fraction and multiply.
11/10 receprical = 10/11
10/11 × 15/4 = 150/44
Now, we simplify.
150/44 = 75/22 = 3 11/22 = 3 1/2
Your answer is 3 1/2.

f) Point K (3,-1)is reflected across the x-axis to creak point K'.The line x+3y=6 passes through point K'.
Answers
Answer: The answer in order are false, false, true, true, false and (3,1)
Step-by-step explanation:
We know that image of a point (x,y) under the y-axis
is (-x,y) i.e. the sign of x coordinate changes
Similarly in case of x-axis sign of y coordinate changes
i.e (x,y) is reflected to (x,-y)
Also the reflection of (x,y) under the line y=x is (y,x)
and the reflection of (x,y) under the line y=-x is(-y,-x)
So
a) Given image of (-3,-5) under x-axis is (3,-5).
Hence statement is false
b) Given image of (1,9) under y-axis is (1,-9)
Hence the statement is false
c) Given image of (8,7) under y=-x is (-7,-8)
i.e. the statement is true
d) Given image of (-6,-6) under y=x is (-6,-6)
i.e the statement is true
e) Given image of (2,4) under y axis followed by x-axis is (-2,-2)
Hence the statement is false
f) (3,-1) is reflected in x-axis to (3,1)
Hence the point k is (3,1)

Number of terms is each amount of individual term. A term is just a number and a variable (possibly to a power/degree). Terms are also separated using a function such as multiplication, addition, and subtraction.
The degree of a polynomial is just the greatest variable's power so if x^5 is the greatest power in that function, than that is the degree of the polynomial

For what value of a does the equation ax^2−3x−5=0 have 1 as one of its roots?
Answers
ax²=3x+5
Now, substitute x for 1 and simplify:
a(1²)=(3×1)+5
1a=3+5
a=8
You can double check this by substituting a for 8 back into the original equation:
(8×1²)-(3×1)-5=0
8-3-5=0
To determine the value of ↑ which the equation ax²-3x-5=0 has 1 as a root, we substitute x=1 into the equation and solve for a, yielding the result that a=8.
To find the value of a for which the equation ax² - 3x-5=0 has 1 as one of its roots, we can substitute x=1 into the equation and solve for a. When x=1, the equation simplifies to:
a(1)² - 3(1) - 5 = 0
a - 3 - 5 = 0
a - 8 = 0
Therefore, a = 8.
This means that the value of a is 8 for the equation to have 1 as one of its roots. This is a direct application of the fact that if a polynomial has a certain number as a root, then by substituting that number in place of the variable, the equation should result in zero.

Can every even number be written as a sum of two primes?
Answers
Final answer:
No, not every even number can be written as a sum of two primes. This is known as the Goldbach Conjecture, which states that every even number greater than 2 can be expressed as the sum of two prime numbers.
Explanation:
No, not every even number can be written as a sum of two primes. This is known as the Goldbach Conjecture, which states that every even number greater than 2 can be expressed as the sum of two prime numbers. So far, this conjecture has been tested for even numbers up to at least 4, and no counterexamples have been found. However, it has not been proven to be true for all even numbers.
For example, the number 4 can be expressed as the sum of two primes (2 + 2), but the number 6 cannot be expressed as the sum of two primes. On the other hand, the number 8 can be expressed as the sum of two primes (3 + 5). This pattern continues, with some even numbers being expressible as the sum of two primes and others not.

Answers
306=X+Y
Where:
X=Janus collected
Y=Arya collected
But:
X=Y-88
Substitute to the equation :
306=(Y-88)+Y
306=2Y-88
2Y=306+88
Y=(306+88)/2
Y=197
Therefore:
X=197-88
X=109
Janus collected $109 while Arya collected $197.
In the neighborhood park there is a circular grassy picnic area, but half of the grass has died. The city wants to replant the grads, but needs to know the square footage of the damaged area. If the circular picnic are is 150 feet across what is the square footage of the damaged area
Answers
.. A = π*(75 ft)^2 ≈ 17,671.459 ft^2
The damaged area is half that, about 8836 ft^2.
Answer: The damaged area is equal to 8831.25ft^2
Step-by-step explanation:
We know that we have a circular area, where half of the grass has died. We know that the circular picnic is "150 feet across" I guess this means that if you walk in a straight line from the edge of the circular area, through the middle, and to the next edge, the distance is 150ft.
This would mean that the diameter is equal to 150ft.
With this we can calculate the total area of the circle; this is:
A = pi*r^2
where r is the radius, that is half the diameter, so we have r = 150ft/2 = 75ft
and pi = 3.14
so we have:
A = 3.14*(75ft^)^2 = 17662.5ft^2
And we know that half of that area has the grass damaged, so the amount of square feet of grass needed is equal to A/2 = (17662.5ft^2)/2 = 8831.25ft^2

Answers
2(4) = 8 +4 = 12/2 = 6*4 = 24
36 +24 = 60
Answer is B
Area = L * W
L = 4b
W = b
Area = 4b * b
Area = 4 *3 * 3
Area = 36 square inches.
Do the trapezoid next
b1 = a
b2 = 2a
h = a
Formula
Area = (b1 + b2) * h / 2
Area = (a + 2a) * a / 2
Area = (3a) * a / 2
a = 4
Area = (3*4) * 4 / 2
Area = 12 * 4/2
Area = 48 /2
Area = 24
Total Area
Area = 24 + 36
Area = 60 in^2

a local post office sells stamps in packs of 4, 6 and 7. andy bought several packs of 4. erin bought several packs of 6. jarred bought several packs of 7. each of the three friends ended up with the same number of stamps that each person could have purchased?
Answers
The number of stamps each could have purchased is 84
How to determine the number of stamps each purchased
From the question, we have the following parameters that can be used in our computation:
Andy = packs of 4
Erin = packs of 6
Jarred = packs of 7
Expand 4, 6 and 7
So, we have
4 = 2 * 2
6 = 2 * 3
7 = 7
The LCM of 4, 6 and 7 is then calculated as
LCM = 2 * 2 * 3 * 7
Evaluate
LCM = 84
Hence, the number of stamps each could have purchased is 84

A parabola has a vertex at (0,0). The focus of the parabola is located on the positive x-axis. Which part of the graph will the directrix pass through? the origin the negative part of the x-axis the positive part of the x-axis the negative part of the y-axis
Answers
Answer with explanation:
→→Information given about Parabola
Vertex of the Parabola = (0,0)
Focus is located on the positive x- axis.
Definition of Parabola: A parabola is locus of all the points such that distance from a fixed point known as focus to distance from a fixed line called, Directrix is always constant.
Let focus of the parabola be (k,0), where , k>0.
Distance between vertex (0,0) and focus(k,0) = Distance between vertex (0,0) and point on negative x-axis (-k,0).
Directrix will pass through point (-k,0).
So, equation of Directrix will be, x= -k
Directrix will pass through

A single card is drawn from a deck. find the probability of selecting a heart or a 8.
Answers

Answer with Step-by-step explanation:
Let
A:selecting a heart
Total cards=52
number of hearts=13
P(A)=13/52
B:selecting a 8
number of 8=4
P(B)=4/52
A∩B:selecting a heart with 8 on it
number of hearts with 8 on it=1
P(A∩B)=1/52
A∪B:selecting a heart or a 8
We have to find P(A∪B)
P(A∪B)=P(A)+P(B)-P(A∩B)
= [tex]\dfrac{13}{52}+\dfrac{4}{52}-\dfrac{1}{52}[/tex]
