Find the vertex angle of the figure below B = 40 egrees
Step-by-step explanation:
it's an Equilateral triangle
the base angels are equal
A=100°
B=40°
C=40°
The required vertex angle will be 100° in the given figure.
What is an Isosceles Triangle?An Isosceles Triangle is defined as a triangle with two sides of equal length is an isosceles triangle.
The triangle given in the figure is an Isosceles triangle.
It is given that side AB is equal to side AC.
So ∠B = ∠C = 40°
Now we know that the sum of angles of a triangle is equal to 180°. So here in this triangle ABC. These are the sum of these three angles will be equal to 180.
As per the given figure,
∠A + ∠B +∠C = 180°
∵ ∠B = ∠C = 40°
∠A + 40° +40° = 180°
∠A + 80° = 180°
∠A = 180° - 80°
∠A = 100°
Therefore, the required vertex angle will be 100° in the given figure.

Answer:
27 minutes.
Step-by-step explanation:
R = k/t
Substituting given info
600 = k/45
k = 45 * 600 = 27000
So the relation is S = 27000/t
So if R = 1000
1000 = 27000/t
t = 27000/ 1000
t = 27.

how do you divide a whole number by a fraction
Answer:Multiply the denominator on the bottom of the fraction by the whole number you are dividing by.
To divide a fraction by a whole number, multiply the bottom of the fraction by this whole number.
The denominator on the bottom of the fraction is 7.
We will multiply 7 by 2.
7 × 2 = 14 and so, 6 / 7 ÷ 2 = 6 / 14 .

In one house , there are 5 hens, 10 goats and 8 cows. there are some man to look after them. If the number of heads is less than 65, then the number of man will be
Answer:
Pretty sure is 42
Step-by-step explanation:
5+10+8=23
65-23=42
The number of men will be 42 if there are 5 hens, 10 goats, and 8 cows.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have:
In one house, there are 5 hens, 10 goats, and 8 cows.
Let H be man's head
H < 65
Total heads = 5 + 10 + 8 =23
Man's heds = 65 - 23 = 42
Thus, the number of men will be 42 if there are 5 hens, 10 goats, and 8 cows.

If there are 4 apples for every 5 oranges, and there are 16 apples, how many fruits are there altogether?
Answer:
36
Step-by-step explanation:
4:5
16:n
16÷4=4
4×5=20
16:20
16+20=36
Answer:
36 fruits (I'm not sure, but I think it's correct)
Step-by-step explanation:
4 apples = 5 oranges
16 apples = ? oranges
4 x ? = 16
4 x 4 = 16
5 x 4 = 20
4 apples = 5 oranges
16 apples = 20 oranges
16 + 20 = 36 fruits
The points (-2, 6) and (3, __ ) are data values of an inverse variation. Fill in the missing value.
Answer: y=6
Step-by-step explanation:
It is inverse so you know it’s y=k/x. Taking the first orders pair you find that k= -12. Then if you put it in y= -12/-2 you get 6 therefore y=6. Your welcome
A: The perimeter of a rectangular garden is 376 m. If the length of the garden is 99 m, what is its width?
B: The area of a rectangular window is 7007 cm If the width of the window is 77 cm, what is his length?
Answer:
A) the width is 89
B) if area is 7007, the length is 91
Step-by-step explanation:
Answer:
A: 89 m
B: 91 m
Step-by-step explanation:
A: P=2(L+W)
P=2L+2W
P=2(99)+2W
2W=376-198=178
W=178/2=89m
B: A=L×W
7007=L×77
L=7007/77=91
L=9l m

Answer: x = 59°, y = 114°.
Step-by-step explanation:
The sum of the opposite angles of a quadrilateral in a circle is 180°.
y = 180° - 121° = 59°
The two angles being adjacent makes a total angle of 180° on the straight line.
x = 180° - (180°-114°) = 180° - 66° = 114°
What expression is equivalent to
15n + 20r
Answer: 5(3n+4r)
Step-by-step explanation:You need to find the gcf/factor .So the gcf of 15 and 20 is 5.So know that you know the gcf ,you divide 15n by 5 which gives you 3n and divide 20r by5 which gives you 4r.Now the last thing you do is,take the GCF which is 5 and place a Parentheses and take 3n and 4r and add them together.
So you get 5(3n+4r) as your expression that is equivalent to 15n + 20r .

PLS PLS HELP!!!! Write and solve an inequality to find the possible values or x if the area of the
rectangle is < 56 feet squared.
2 ft
(3x + 4) ft
Answer:
width=2 ft, length=(3x+4)ft
Area of Rectangle=width x length
=2ft . (3x+4)ft
=6x+8 ft sq
Area of Rectangle <56 ft sq
6x+8 ft sq <56 ft sq
6x < 56 ft sq - 8 ft sq
6x < 48 ft sq Substeracting 8 on both sides
6x/6 < 48 ft sq/6 Dividing by 6 on both sides
x < 8 ft sq

Answer:
33, 57
(not 100% sure this is correct)
Step-by-step explanation:
90= x +(24 +x)
(drag 90, plus the x's and drag the 24)
90 = 2x + 24
(Subtract 24 from 24 and 90 from 24)
66 = 2x
(Divide both by two)
33 = x
(now use x and plus it by 24)
24 + x = 57

The two triangles are similar and therefore we can set up a proportion
9/(9 + 72) = (3x - 20)/(3x - 20 + 56) Combine like terms on the right
9/(81) = (3x - 20)/(3x + 36) Cross multiply
9(3x + 36) = 81 (3x - 20) Remove the brackets.
27x + 324 +1620 = 243x Add 1620 to both sides
27x + 324 + 1620 = 243x Subtract 27x from both
1944 = 216x divide both sides by 216
x = 9
If you feel comfortable canceling the size of the numbers can be reduced.
9/81 = 1/9
1/9 = (3x - 20)/(3x + 36)
3x + 36 = 9(3x - 20)
3x + 36 = 27x - 180
36 + 180 = 24x
216 = 24x
216/24 = x
x = 9
There is another cancelation possible, but this is simple enough.

Vector B has x, y, and z components of 3, 7.2,
and 4.5 units, respectively.
Calculate the magnitude of B
Answer:
[tex]\approx 9.0\:\mathrm{units}[/tex]
Step-by-step explanation:
The magnitude of 3D vector [tex]\vec{v}[/tex] can be given by the following:
[tex]| \overline{v}| =\sqrt{{v_x}^2+{v_y}^2+{v_z}^2}[/tex]
Plugging in given values, we have:
[tex]| \overline{v}|=\sqrt{3^2+7.2^2+4.5^2},\\| \overline{v}| \approx \fbox{$9.0\:\mathrm{units}$}[/tex].

170/100 * 85 = 144.5
144.5 - 85 = 59.5
If that is wrong my next guess is $144.50
