Answer:
24 [tex]m^{2}[/tex]
Step-by-step explanation:
Area of parallelograms is :
A = b x h
The height must be a line perpendicular to the base.
The slant measuring 5 is not perpendicular to the base.
A = 6 x 4
A = 24

A line contains the points R (-5, -6) S (1, 5) and T (x, 10). Solve for x. Be sure to show and explain all work
Answer:
x is 3.[tex]\overline{72}[/tex]
Step-by-step explanation:
The given points on the line are;
R(-5, -6), S(1, 5) and T(x, 10)
The number of points required to find the equation of the line = 2 points
The slope, m, of the line using points R(-5, -6) and S(1, 5) is given as follows;
m = (5 - (-6))/(1 - (-5)) = 11/6
The equation of the line in slope and point form, using point S(1, 5) is therefore;
y - 5 = (11/6)·(x - 1) = 11·x/6 - 11/6
y - 5 = 11·x/6 - 11/6, given that the x-value is required, we have;
x = (y - 5 + 11/6) × 6/11 = 6·y/11 - 19/11
x = 6·y/11 - 19/11
At point T(x, 10), y = 10, therefore, we have;
x = 6×10/11 - 19/11 = 41/11 = 3.[tex]\overline{72}[/tex]
x = 3.[tex]\overline{72}[/tex].

surface area of cylinder
Answer:
The answer is C. [tex]256\pi[/tex] [tex]in^2[/tex].
Step-by-step explanation:
To solve for the surface area of this cylinder, start by using the cylinder surface area formula, which is [tex]SA=2\pi rh+2\pi r^{2}[/tex]. Next, plug in the information given from the problem into the formula, which will look like [tex]SA=(2)(\pi )(8in)(8in)+(2)(\pi )(8in^{2})[/tex]. Then, simplify the equation, which will look like [tex]SA=(128in)(\pi) +(128in)(\pi)[/tex]. The next step is to simplify the equation further, which will look like [tex]SA= 256\pi[/tex] [tex]in^{2}[/tex]. The final answer is [tex]256 \pi[/tex] [tex]in^2[/tex].
A group of friends is addressing wedding invitations. Casey can address 22 envelopes in one hour, Anne can address 48 envelopes in two hours, and Paula can address 62 envelopes in three hours. About how long will it take them to address 420 envelopes?
A.
19.09 hours
B.
22.00 hours
C.
7.24 hours
D.
6.30 hours
Answer:
D
Step-by-step explanation:
Let's say that we have x amount of hours.
Casey addresses 22 envelopes per hour. Another way of writing this is that for x hours, Casey addresses 22 envelopes. Therefore, given x hours, Casey addresses 22 * x envelopes.
Anne can address 48 envelopes in 2 hours. It is important to note that this is for 2 hours. To make this per 1 hour, we can write
48 envelopes = 2 hours
divide both sides by 2
24 envelopes = 1 hour.
Therefore, given x hours, Anne addresses 24 * x envelopes.
Paula can address 62 envelopes in 3 hours, so
62 envelopes = 3 hours
divide both sides by 3
62/3 envelopes = 1 hour
Given x hours, Paula can address 62/3 * x envelopes.
Adding all of these up, given x hours, the group of friends can address
22 * x + 24 * x + 62/3 * x envelopes. Because the variables are all the same (x), we can add up the coefficients, resulting in
(22 + 24 + 62/3) * x = (46 + 62/3) * x envelopes given x hours
We want to figure out the amount of hours (x) for 420 envelopes. The total amount of envelopes is equal to (46 + 62/3) * x, so we set 420 equal to that, resulting in
(46 + 62/3) * x = 420
divide both sides by (46 + 62/3) to isolate x
420 / (46 + 62/3) = x
= 6.3 hours

Find the length of the side and area ot the square whose perimeter is given below a)44cm b)80cm
9514 1404 393
Answer:
a) 11 cm
b) 20 cm
Step-by-step explanation:
A square has four equal-length sides, so the perimeter is 4 times the side length. Then the side length is 1/4 of the perimeter.
a) s = (1/4)(44 cm) = 11 cm
b) s = (1/4)(80 cm) = 20 cm
Instructions: Solve the triangle, find mA and mZC.
Step-by-step explanation:
mA=cosA=17/38
A=cos inverse of 17/38
A=63 degrees

39. a(x + 3) < 5x + 15 - x
Answer:
x < [tex]\frac{15-3a}{a-4}[/tex]; a > 4
a < [tex]\frac{4x+15}{x+3}[/tex]
Step-by-step explanation:
ax+3a < 4x + 15
ax - 4x < 15 - 3a
x( a -4) < 15 - 3a
x < [tex]\frac{15-3a}{a-4}[/tex]
ax + 3a < 5x + 15 -x
ax + 3a < 4x + 15
a( x + 3) < 4x + 15
a < [tex]\frac{4x+15}{x+3}[/tex]
Answer:
x < (15 - 3a) / (a - 4). ( only true if a > 4)
a < (x + 15)/x
Step-by-step explanation:
a(x + 3) < 5x + 15 - x
ax + 3a < 5x + 15 - x
ax - 5x + x < 15 - 3a
ax - 4x < 15 - 3a
x(a - 4) < 15 - 3a
Dividing both sides by (a - 4):
x < (15 - 3a) / (a - 4)
a < (x + 15)/x

[tex]6 {x}^{6} + 6 {x}^{4} + 6 {x}^{2} [/tex]
Answer:
(6x^2)(x^4 +x^2 + 1)
Step-by-step explanation:
6x^6 + 6x^4 + 6x^2
split it up into parts
6x^6 = (6x^2) * x^4
6x^4 = (6x^2) * x^2
6x^2 = (6x^2) * 1
so you can take out 6x^2 to get
(6x^2)(x^4 +x^2 + 1)

Please help me find x
Need help fast!!
Answer:
x = 100°
Step-by-step explanation:
p and q are parallel lines. Construct line 'l' parallel to p and q
a = 30° {p// l when parallel lines are intersected by transversal alternate interior angles are congruent}
c +110 = 180 {linear pair}
c = 180 - 110
c = 70°
b= c {q // l when parallel lines are intersected by transversal alternate interior angles are congruent}
b = 70°
x = a + b
x = 30° + 70°
x = 100°

3. Find the measure of angle A.
Answer:
20
Step-by-step explanation:
Angle Formed Outside = 1/2(difference of Intercepted Arcs)
The outside arc = 360-160 = 200
A =1/2 (200-160)
A = 1/2 (40)
A = 20

Một lớp có 40 học sinh gồm học sinh giỏi, học sinh khá , và học sinh trung bình , số hs trung bình chiếm 1/4 cả lớp , số hs khá bằng 60% số học sinh còn lại a) tính số học sinh mỗi loại B) tổng số hs khá và giỏi chiếm bao nhiêu phần trăm trong lớp
Answer:
Đổi 60% = 3/5
a) Số học sinh trung bình là: 40 * 1/4 = 10 (hsinh)
Tổng số hsk và hsg là: 40 - 10 = 30 (hsinh)
Số học sinh khá bằng 60% số học sinh còn lại nên số hsk là:
30 * 60% = 18 (hsinh)
Số học sinh giỏi là: 30 - 18 = 12 (hsinh)
b) Tổng số hs khá và giỏi chiếm số phần trăm trong lớp là:
30 : 40 * 100 = 75%
