Answer:
Step-by-step explanation:
Question #1:
Area of a triangle = bh/2
A = (3)(6)/2 = 18/2 = 9 in²
Total A = 10 x area of a triangle
Total A = 10 x 9 = 90 in²
Question #2:
A = bh/2
Top 2 triangles: (20)(10)/2 x 2 = 200
Bottom 2 triangles: (20)(50)/2 x 2 = 1000
Total A = 1,200 in²
Question #3:
Total area = 2 triangles + 1 square
Triangle A: must find base
a² + b² = c²4² + b² = 6²b = √(36 - 16) = √20 = 2√5Triangle A = bh/2 = (2√5)(4) = 8√5
Square A = bh = (4)(?)
The last one is very hard, can't find the square's base. I hope the rest of my answers help though! Have a nice day!

First we have to add the gallons of two cow of each owner:
Hank's cows: 4 3/4 + 4 1/8
Add the whole numbers:
4 + 4 = 8
Now for 3/4 and 1/8
Find common
6/8 + 1/8
= 7/8
Put together :
8 7/8
Debra's cows: 5 1/2 + 5 2/3
Add the whole number
5 + 5 = 10
Now for 1/2 and 2/3
3/6 + 4/6
1 1/6
10 + 1 1/6
= 11 1/6
Since now we know that:
Hank - 8 7/8
Debra - 11 1/6
we can solve the question:
How many more gallons of milk did Debra's two cows produce on that compared to Hank's two cows?
Solution:
11 1/6 - 8 7/8
Subtract whole number
11 - 8 = 3
Now for 1/6 and 7/8
4/24 - 21/24
4-21/24
-17/24
2 7/24
~lenvy~
Answer:
2 7/24
Step-by-step explanation:
Hank Cows:
4 3/4 and 4 1/8
Debra Cows:
5 1/2 and 5 2/3
To find the difference between Hank cows and Debra cows..
we first have to add both cows together:
4 3/4 + 4 1/8 = 8 7/8 {Hank}
5 1/2 + 5 2/3 = 11 1/6 {Debra}
Since now we know Hank and Debra total gallons of milk we can solve and find out the difference.
11 1/6 - 8 7/8 = 2 7/24
Hence, Debra have 2 7/24 more gallons of milk than Hank.

What is the probability of getting a number greater than 2 on two rolls of a six-sided die both
times?
a. 2/6
b.4/6
c.4/3
d.3/6
e.4/9
Answer:
[tex]Probability = \frac{4}{9} [/tex]
Given:
The die was rolled twice having six sides,
To find:
probability of getting a number greater than 2 =?
solution:
The probability of getting a number greater than 2 on single roll =
[tex] \frac{4}{6} = \frac{2}{3} [/tex]
Similarly on second roll the probability would be
[tex] \frac{2}{3} [/tex]
Since two events are occurring together, the total probability of finding number greater than 2 in both rolls =
[tex] \frac{2}{3} \times \frac{2}{3} = \frac{4}{9} [/tex]

find the value of x super easy 7th grade math
Answer:
x = 50 degrees
Step-by-step explanation:
all the angles of a triangle add up to 180
a right angle is ninety degrees
90 + the 40 degrees on the top is 130 degrees
180 - 130 is 50
x = 50
Answer:
50°[tex] \: [/tex]
Step-by-step explanation:
Before finding the value of x, we must know this first.
[tex] \\ \longrightarrow \qquad { \underline{ \boxed{ \pmb{ \frak{Sum \: of \: all \: \: angles_{(Triangle)} = 180 {}^{ \circ} }}}}} \: \: \bigstar \\ \\ [/tex]
This is a right angled triangle so,
[tex] \\ \longrightarrow \qquad { { { \pmb{ \sf{ \angle \: 1 +\angle \: 2 + \angle \: 3= {180}^{ \circ} }}}}} \\ \\ [/tex]
[tex]\longrightarrow \qquad { { { \pmb{ \sf{ x^{ \circ} + {90}^{ \circ} + {40}^{ \circ} = {180}^{ \circ} }}}}} \\ \\ [/tex]
Adding like terms we get :
[tex] \\ \longrightarrow \qquad { { { \pmb{ \sf{ x^{ \circ} + {130}^{ \circ} = {180}^{ \circ} }}}}} \\ \\ [/tex]
Subtracting 130° from both sides :
[tex] \\ \longrightarrow \qquad { { { \pmb{ \sf{ x^{ \circ} + {130}^{ \circ} - {130}^{ \circ} = {180}^{ \circ}- {130}^{ \circ}}}}}} \\ \\ [/tex]
[tex]\longrightarrow \qquad { \underline { \boxed{ \pmb{ \frak{ x^{ \circ} = {50}^{ \circ}}}}}} \: \: \bigstar\\ \\ [/tex]

Blank × 100 =23 find the missing number
Answer:
blank = 0.23
Step-by-step explanation:
to do this you can divide both sides by 100
23/100 is 0.23
blank = 0.23
Answer:
0.23 or 23/100
Step-by-step explanation:
1) Start by setting up an equation
We'll say that x represents the blank.
100x = 23
2) Solve
100x = 23
Divide both sides by 100
x = 0.23 or 23/100

Answer:
\sf (x+14)^2+(y+5)^2=149(x+14)2+(y+5)2=149
Step-by-step explanation:
Standard equation of a circle: \sf (x-a)^2+(y-b)^2=r^2(x−a)2+(y−b)2=r2
(where (a, b) is the center and r is the radius of the circle)
Substitute the given center (-14, -5) into the equation:
\sf \implies (x-(-14))^2+(y-(-5))^2=r^2⟹(x−(−14))2+(y−(−5))2=r2
\sf \implies (x+14)^2+(y+5)^2=r^2⟹(x+14)2+(y+5)2=r2
Now substitute the point (-7, 5) into the equation to find r²:
\sf \implies ((-7)+14)^2+(5+5)^2=r^2⟹((−7)+14)2+(5+5)2=r2
\sf \implies (7)^2+(10)^2=r^2⟹(7)2+(10)2=r2
\sf \implies 149=r^2⟹149=r2
Final equation:
\sf (x+14)^2+(y+5)^2=149(x+14)2+(y+5)2=149

Find the angle between v=i+2j+3k and w=4i-k.
:2
.
Answer:
86.28 degrees
Step-by-step explanation:
Angle between vectors is
[tex] \cos(x) = \frac{cross \: product}{magnitudes \: multiplied} [/tex]
The cross product is
[tex]4 + 0 - 3 = 1[/tex]
The magnitudes of first vector is
[tex] \sqrt{1 {}^{2} + 2 {}^{2} + 3 {}^{2} } = \sqrt{14} [/tex]
The second vector magnitude is
[tex] \sqrt{17} [/tex]
So the magnitudes multiplied is
[tex] \sqrt{14} \times \sqrt{17} = \sqrt{238} [/tex]
So our equation will be
[tex] \cos(x) = \frac{1}{ \sqrt{238} } [/tex]
[tex]x = \cos {}^{ - 1} ( \frac{1}{ \sqrt{238} } ) [/tex]
X is about 86.28 degrees

What is the scale factor of the enlargement of shape A to shape B?
Answer:
scale factor = 6
Step-by-step explanation:
the scale factor is the ratio of corresponding sides, shape B to shape A
base of shape A = 1 , base of shape B = 6 , then
scale factor = [tex]\frac{6}{1}[/tex] = 6
After finding the ratio of their corresponding sides of triangles the scale factor we get is 6.
The difference in scale between an original item's scale and a new object that is its representation but is larger or smaller is known as a scale factor.
From figure
For small triangle:
base = 1 units
For large triangle:
base = 6 units
Now the scale factor = ratio of adjacent sides
Scale factor = (Base of large triangle)/(Base of small triangle)
Scale factor = 6/1
Scale factor = 6
Hence,
The scale factor is 6.

Find the mass of a sphere of radius 7 if δ= kρ, k a constant.
Presumably, both δ and ρ represent density of some object. Considering the context, ρ is likely a function of 3 variables, ρ = ρ(x, y, z). Then the mass of the sphere with the prescribed density δ(x, y, z) = k ρ(x, y, z) is
[tex]\displaystyle \iiint_B k \rho(x,y,z) \, dx\, dy\, dz[/tex]
where B is the set
[tex]B = \left\{(x,y,z) ~ : ~ x^2+y^2+z^2 \le 7^2\right\}[/tex]
If you have all the details at hand, you can compute the integral by converting to spherical coordinates, substituting
[tex]\begin{cases}x = u \cos(v) \sin(w) \\ y = u \sin(v) \sin(w) \\ z = u \cos(w)\end{cases} \text{ and } dx\,dy\,dz = u^2 \sin(w) \, du \, dv \, dw[/tex]
The integral then transforms to
[tex]\displaystyle k \int_0^{2\pi} \int_0^\pi \int_0^7 \rho(u\cos(v)\sin(w),u\sin(v)\sin(w),u\cos(w)) \, u^2 \sin(w) \, du \, dw \, dv[/tex]

Given m n, find the value of x.
(7X-10)9
(6x-5)°
Answer:
x = 15
Step-by-step explanation:
Since m and n are parallel to the line t.
Then (7x - 10) + (6x - 5) = 180° supplementary angles for a linear pair.
(7x - 10) + (6x - 5) = 180°
13x -15 = 180°
13x = 195°
x = 15
Plug x into the angles to solve for angle.
(7x - 10)
(7*15 - 10) = 105 - 10 = 95°
(6x - 5) =
(6*15 - 5) = 90 - 5 = 85°

What is the equation of the line that passes through the point (4,1) and has a slope
of 1/2
Linear equations are usually organized in slope-intercept form, which looks like this:
[tex]y=mx+b[/tex]
m is the slope of the lineb is the y-intercept (the value of y when the line passes through the y-axis)To find the equation of a line in slope-intercept form:
Determine the slope of the linePlug the slope into the general formDetermine the y-intercept by solving for b Plug b back into the equationSolving the QuestionWe're given:
m = [tex]\dfrac{1}{2}[/tex](4,1) falls on the lineFirst, plug the given slope into the slope-intercept form equation:
[tex]y=mx+b\\\\y=\dfrac{1}{2}x+b[/tex]
Now, determine the y-intercept.
