Answer:
For all of these triangles apply the formula;
A = BH x 1/2
Where 'B' represents the base, 'H' stands for the height, and 1/2 just means to divide the product of the two lengths (base x height) by 2.
1.
Base = 9.1
Height = 31.2
Plug into formula:
A = BH x 1/2
A = 9.1(31.2) x 1/2
A = 283.92 x 1/2
A = 283.92/2
A = 141.96 square centimetres.
2.
Base = 5
Height = 3 3/4 which can be considered 3.75
Plug into formula:
A = BH x 1/2
A = 5(3.75) x 1/2
A = 18.75 x 1/2
A = 18.75/2
A = 9.375 square kilometres.
3.
Base = 2.4
Height = 3.2
Plug into formula:
A = BH x 1/2
A = 2.4(3.2) x 1/2
A = 7.68 x 1/2
A = 7.68/2
A = 3.84 square inches.
4.
Base = 11
Height = 60
Plug into formula:
A = BH x 1/2
A = 11(60) x 1/2
A = 660 x 1/2
A = 660/2
A = 330 square millimetres.
5.
Base = 10
Height = 13 1/2 which can be considered 13.5
Plug into formula:
A = BH x 1/2
A = 10(13.5) x 1/2
A = 135 x 1/2
A = 135/2
A = 67.5 square feet.
Answer:
1. 141.96 cm²
2. 9⅜ km²
3. 3.84 in
4. 10.39mm
5. 66.67 ft
Step-by-step explanation:
Formula of Area of Triangle : ½ × base × height
1. = ½ × 9.1 × 31.2
= 9.1 × 15.6
= 141.96 cm²
2. = ½ × 3¾ × 5
= ½ × 15/4 × 5
= 15/8 × 5
= 75/8 = 9⅜ km²
3. = ½ × 3.2 × 2.4
= 3.84 in
4. = tan c = AB/BC
c = tan -¹ (AB/BC)
c = tan -¹ (60/11)
c = 79.61
A = 90 - 79.61 = 10.39mm
5. = ½ × 13⅓ × 10ft
= 66.666 ≈ 66.67 ft

Jose made 5 2/3 cups of juice. He served 3/4 of it at dinner. Which equation shows the amount of juice that Jose served?
Answers
Answer:
4 1/4 cups were served
Step-by-step explanation:
Just multiply 5 2/3 cups by 3/4:
17 3
---- * ---- = 4 1/4 cups were served.
3 4
An equation shows the amount of juice that Jose served is x= 3/4 × 17/3.
What is the product of two fractions?The product of two fractions is the product of the numerators and the product of the denominators.
Product of two fractions = Product of their numerators / Product of their denominators.
Given that, Jose made [tex]5\frac{2}{3}[/tex] cups of juice. He served 3/4 of it at dinner.
Here, [tex]5\frac{2}{3}[/tex] cups can be written as 17/3
Let the amount of juice that Jose served be x
Now, x= 3/4 × 17/3
x= 17/4
x= [tex]4\frac{1}{4}[/tex] cups
Therefore, an equation shows the amount of juice that Jose served is x= 3/4 × 17/3.

Y(5,-3)
Z(-7, 1)
a) Rotate the points 90 degrees clockwise
b) Dilation by a scaling factor of 2
c) Reflect across the x-axis
d) Translation 2 Up and 5 to the Left
Answers
Transforming the points involves changing their coordinates
The image of the points are: (3, 6), (-11, 12) and (-3, -12)
How to complete the transformations?The coordinates of the points are given as:
X(2, 4)
Y(5,-3)
Z(-7, 1)
a) Rotate the points 90 degrees clockwiseThe rule of this transformation is:
(x, y) to (y, -x)
So, we have:
X' = (4, -2)
Y' = (-3, -5)
Z' = (1, 7)
b) Dilation by a scaling factor of 2The rule of this transformation is:
(x, y) to (2x, 2y)
So, we have:
X'' = (8, -4)
Y'' = (-6, -10)
Z'' = (2, 14)
c) Reflect across the x-axisThe rule of this transformation is:
(x, y) to (x, -y)
So, we have:
X''' = (8, 4)
Y''' = (-6, 10)
Z''' = (2, -14)
d) Translation 2 Up and 5 to the LeftThe rule of this transformation is:
(x, y) to (x -5, y + 2)
So, we have:
X'''' = (3, 6)
Y'''' = (-11, 12)
Z'''' = (-3, -12)
Hence, the image of the points are: (3, 6), (-11, 12) and (-3, -12)

A one solution
C no solution
B two solutions
D infinite
Answers
Answer:
D
Step-by-step explanation:
3s = 8s - 5s
8s = 8s
s = 0, 1, 2, 3.......
so infinite solutions
D)
Step-by-step explanation:Given equation:
[tex]3s = 8s - 5s[/tex]To simplify this equation, we need to isolate the variables on one side of the equation and the constants on the other side of the equation. To do this, we can simplify the R.H.S as like terms can subtract.
⇒ [tex]3s = 8s - 5s[/tex]
⇒ [tex]3s = s(8 - 5)[/tex]
⇒ [tex]3s = s(3) = 3s[/tex]
⇒ [tex]3s= 3s[/tex]
Since both sides of the equation are the same, this system of equations has infinite solutions.
Check:We can check our answer by substituting the value of "s" into the equation. As a result, you will see that many values of "s" are satisfying the equation. Thus, Option D is correct.

How to solve [tex]2n =\frac{15}{2}[/tex] and [tex]\frac{1}{4} =\frac{n}{5}[/tex] ???
Answers
Answer:
[tex]2n=\dfrac{15}{2}[/tex]
Multiply both sides by 2:
[tex]\implies 2 \cdot 2n=2 \cdot \dfrac{15}{2}[/tex]
[tex]\implies 4n=15[/tex]
Divide both sides by 4:
[tex]\implies \dfrac{4n}{4}=\dfrac{15}{4}[/tex]
[tex]\implies n=\dfrac{15}{4}[/tex]
[tex]\dfrac14=\dfrac{n}{5}[/tex]
Multiply both sides by 5:
[tex]\implies 5 \cdot \dfrac14=5 \cdot \dfrac{n}{5}[/tex]
[tex]\implies \dfrac54=n[/tex]
[tex]\implies n=\dfrac54[/tex]
Answer:
Step-by-step explanation:
2n = 15/2
Divide both sides b y 2:
n = 15/2 / 2
= 15/2 * 1/2
= 15/4.
1/4 = n / 5
Multiply both sides by the LCM (20):
20/4 = 20n/5
5 = 4n
n = 5/4.

Find the slope of the line that is parallel and perpendicular to the following equation.
2x-2y=-6
Answers
Answer:
Parallel lines 1
perpendicular lines -1
Step-by-step explanation:
2x-2y = -6
Solve for y to get it in slope intercept form
-2y = -2x-6
Divide by -2
y = x+3
This is slope intercept form y = mx+b where m is the slope
Parallel lines have the same slope
A parallel line would have a slope of 1
Perpendicular lines would have a slope that is a negative reciprocal
-1/1
Perpendicular lines would have a slope of -1
Let us first put it into slope-intercept form ⇒ [tex]y = mx + b[/tex]
m: slopeb: y-intercept of the functionTo put it into that format, we need to simply put y on one side of the equation and the rest on the other side
[tex]2x - 2y =-6\\-2y = -2x -6\\y = x +3[/tex]
What do we want to find first ⇒ a line parallel to the original line
a line that is parallel to the original line only has one requirement, it must have the same slope, such as the one below[tex]y = x +5[/tex]
What do we also want to find ⇒ a line perpendicular to the original line
a line that is perpendicular to the original line only has one requirement, the slope has to be the negative reciprocal of the original slope⇒ original slope is 1 ⇒ negative reciprocal is - 1/1 = -1
⇒ so an example is
[tex]y = -x + 3[/tex]
Answer:
Line that is parallel: slope is 1Line that is perpendicular: slope is -1Hope that helps!
