Answer:
45mm
Step-by-step explanation:
First, find the whole area of the square, which is 225 mm squared.
Then, we have to find the area of the shaded trapezoid. Remember, the area of the trapezoid is [tex]\frac{h(b^{1}+b^{2} }{2}[/tex]
We get the area of the trapezoid to be 180 mm.
We subtract 180 from 225 mm to get 45 mm as our answer.

This is because alternate exterior angles are congruent when we have parallel lines like this.
Angle 2 and angle 8 are both outside the parallel lines, so that's what makes them exterior angles. Also, they are on alternating sides of the transversal line (angle 2 on the left, angle 8 on the right). So that's where the "alternating" comes from. The other pair of alternate exterior angles is angle 1 and angle 7.

Answers

Answer:
3. $6000 at 8%; $5000 at 5%
4. 66 2/3 gallons of 9%; 133 1/3 gallons of 6%
Step-by-step explanation:
For many mixture problems, it works well to let a variable represent the amount of the largest contributor used in the mix.
3. Let x represent the amount invested at 8%. Then the total interest is ...
8%x +5%(11000-x) = 730
3%x = 730 -550
x = 180/0.03 = 6000
$6000 was invested at 8%; $5000 was invested at 5%.
__
4. Let x represent the number of gallons of 9% content. Then the alcohol content of the mix is ...
9%x +6%(200 -x) = 7%(200)
3%x = 1%(200) . . . . . subtract 6%(200)
x = 200/3 = 66 2/3 . . . . . divide by 3%
200 -x = 133 1/3
66 2/3 gallons of 9% wine and 133 1/3 gallons of 6% wine should be used.

so it would be x = 11-2y
so now the 1st equation would be 3(11-2y)+6y
Expand so its 33-6y+6y
So its just 33
Knowing that y is now 33
We use that into either equations, so x+2y=11
Would be x+66=11
So x is -55

There are 43 tiles in a bag. The colors are red, blue, green and yellow. Find the
number of each color tile given the following ratios:
red : blue = 2 : 3 blue : green = 2 : 1 green : yellow = 2 : 5
what is the number of tiles of each color??
Answers
Answer:
43/13, 129/26, 129/13, 645/26
Step-by-step explanation:
Let w represent the number of red tiles, x represent the number of blue tiles, y represent the number of green tiles and z represent the number of yellow tiles. Hence:
w + x + y + z = 43 (1)
x = 3/5(w + x)
2x/5 = 3w/5
x = 3/2(w)
x = 5w/2 - w = 3w/2 (2)
y = 2/3(x + y)
y/3 = 2x/3
y = 2x = 2(3w/2) = 3w (3)
z = 5/7(y + z)
2/7(z) = 5y/7
z = 5y/2 = 5(3w)/2 = 15w/2 (4)
substitute x = 3w/2, y = 3w and z = 15w/2 in equation 1:
w + 3w/2 + 3w + 15w/2 = 43
13w = 43
w = 43/13
x = 129/26
y = 3w = 129/13
z = 645/26

A scoop of ice cream in the shape of a whole sphere sits in a right cone. the radius of the ice cream scoop is 2.5 cm and the radius of the cone is 2.5 cm. How tall must the height of the cone be to fit all the ice cream without spilling if it melts? SHOW ALL YOUR WORK!!!
Answers
Answer:
(At least) 10 centimeters.
Step-by-step explanation:
The radius of the ice cream scoop is 2.5 cm and the radius of the cone is also 2.5 cm.
We want to determine the height of the cone such that it will fit all of the ice cream when it melts without any spilling.
First, we will find the volume of the ice cream scoop. The volume for a sphere is given by:
[tex]\displaystyle V=\frac{4}{3}\pi r^3[/tex]
Since the radius is 2.5 cm, the volume of the full ice cream scoop is:
[tex]\displaystyle V=\frac{4}{3}\pi (2.5)^3[/tex]
Use a calculator:
[tex]V\approx 65.4498\text{ cm}^3[/tex]
The volume of a cone is given by:
[tex]\displaystyle V=\frac{1}{3}\pi r^2h[/tex]
The radius of the cone is 2.5 cm. Therefore:
[tex]\displaystyle V=\frac{1}{3}\pi(2.5)^2h=\frac{1}{3}\pi(6.25 h)=\frac{6.25\pi}{3}h[/tex]
The volume of the cone should be equal to the volume of the scoop. So:
[tex]\displaystyle 65.4498=\frac{6.25\pi}{3}h[/tex]
Solve for h:
[tex]\displaystyle h\approx 65.4498\Big(\frac{3}{6.25\pi}\Big)=10\text{ cm}[/tex]
The height of the cone should be (at least) 10 cm.

Five times a number is 49 greater than the product of 2 and the opposite of the number, What is the number?
Answers
Answer:
The answer is 7
Step-by-step explanation:
5x+2x=49-2x+2x
7x=49+0
7x/7=49/7
x=7
The number is 7 if five times a number is 49 greater than the product of 2 and the opposite of the number.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Five times a number is 49 greater than the product of 2 and the opposite of the number.
Let the number is x:
From the statement "Five times a number is 49 greater than the product of 2 and the opposite of the number" we can frame a linear equation in one variable:
5x + 2x = 49 - 2x + 2x
After solving the above equation:
7x = 49
x = 49/7
x = 7
Thus, the number is 7 if five times a number is 49 greater than the product of 2 and the opposite of the number.

Mark has, in his kitchen, the ingredients needed to prepare 78 different recipes with two ingredients
each. Of those 78 different recipes, there are no two recipes that share the exact same two ingredients.
How many ingredients does he have?
Answers
Answer:
13 ingredients
Step-by-step explanation:
The number of different recipes that can be made from 2 ingredients = 78
Since there are no two recipes that share the exact same two ingredients ;
The number of recipes in Mark's kitchen is:
nCk = 78
k = Number of ingredients per recipe = 2
n = total number of ingredients in kitchen
Total recipes made = 78
n! / (n-r)!r! = 78
n! / (n - 2)!2! = 78
n(n-1)(n-2)! / (n-2)! * 2 * 1 = 78
n(n - 1) / 2 = 78
n(n-1) = 156
n² - n = 156
n² - n - 156 = 0
Factorize :
n² - 13n + 12n - 156 = 0
n(n - 13) +12(n-13) = 0
(n-13) = 0 ; (n+12) = 0
n = 13 or n = - 12
n cannot be negative
Hence, n = 13
Number of ingredients is 13
