Answer:
Step-by-step explanation:
a+b=-14
a=-14-b
ab=33, using a from above makes this become
(-14-b)b=33
-14b-b^2=33
b^2+14b+33=0
(b+11)(b+3)=0
So the numbers are -3 and -11

find the simple interest principle 950 interest rate 12% time 4 years
Answer:
A= $1406
Step-by-step explanation:
The formula for simple interest is A=P(1+rt), where P=Principal, R=Rate, and T=Time. Before you plug your numbers into your formula, you must first convert 12% to a decimal (This is simple because all you have to do is divide 12 by 100.)- 0.12.
Now, you can plug your numbers into the formula: A=950(1+0.12x4). To make this less complex, I suggest working in the parenthesis first- specifically simplifying rt, or multiplying 0.12 by 4 (you should get 0.48)! Now, you are just about ready to go. A=950(1+0.48)- You can plug this into your calculator as is, or you can go on ahead and add the numbers in the parenthesis if that makes you feel better! (You should get 1.48).
Your final formula should be 950(1.48), and you should plug this into a TEACHER-APPROVED CALCULATOR to save time!
Your final answer should be $1406, otherwise you did something wrong! XD!
what is the value of x and y?
Answer:
The right answer is x = 8, y = 40.
Step-by-step explanation:
Since this triangle is isosceles we know that...
∠ACB = ∠ABC
40° = (5x)°
40 = 5x
x = 40 / 5
x = 8
We also know that the sum of all angles inside the triangle is equal to 180°, therefore...
∠BAC = 180° - ∠ACB - ∠ABC
(2y + 20)° = 180° - 40° - 40°
2y + 20 = 100
2y = 100 - 20
2y = 80
y = 80 / 2
y = 40
From this, we know that the right answer is x = 8, y = 40.

Division in a given ratio
In a class of 30 pupils the ratio of the number of boys to the number of girls is 7 : 8. How many girls are there?
Step-by-step explanation:
let the ratio 7:8 be 7x and 8x.
now
7x+8x=30
or, 15x=30
or, x= 30/ 15
or, x= 2
here
no. of boys = 7x= 7*2 = 14
no. of girls= 8x = 8*2= 16
hope this helps u...
Answer:
16 girls
Step-by-step explanation:
sum the parts of the ratio, 7 + 8 = 15 parts
Divide the number of pupils by 15 to find the value of one part of the ratio.
30 ÷ 15 = 2 pupils ← value of 1 part of the ratio, then
8 parts = 8 × 2 = 16 ← number of girls
If the sum of the measures of the interior angles of a polygon is 1920°, how many sides does it have? math
Answer: There is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.
Step-by-step explanation:
The sum of the measures of interior angles of a polygon with [tex]n[/tex] sides is given by:-
[tex](n-2)\times180^{\circ}[/tex]
Given: The sum of the measures of the interior angles of a polygon is 1920°.
i.e. [tex](n-2)\times180^{\circ}=1920^{\circ}[/tex]
[tex]n-2=\dfrac{1920}{180}\\\\ n= \dfrac{1920}{180}+2\\\\ n=\dfrac{2280}{180}=12.67[/tex]
But number of sides cannot be in decimal.
Hence, there is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.

Ron and Freddy built structures out of snap cubes. Ron's tower had an 8-inch square base. Freddy had a 6-inch square base. If Ron's tower had a volume of 320 cubic inches and Freddy's had a volume of 180 cubic inches, Whose tower was taller? Explain your reasoning.
Answer: Ron tower's
Step-by-step explanation:
Given
Ron tower has a base of [tex]A_r=8\ in.^2[/tex]
Freddy tower has a base of [tex]A_f=6\ in.^2[/tex]
Suppose the tower is in the shape of a square prism
The volume of Ron and Freddy tower is [tex]320\ \text{and}\ 180\ in.^3[/tex]
The volume of a square-based prism is [tex]V=\frac{1}{3}a^2h[/tex]
[tex]\therefore \text{height of Ron tower is}\ h_r=\dfrac{3V}{A_r}\\\\\Rightarrow h_r=\dfrac{3\times 320}{8}=120\ in.[/tex]
The height of Freddy tower is
[tex]\Rightarrow h_f=\dfrac{3V}{A_f}\\\\\Rightarrow h_f=\dfrac{3\times 180}{6}=90\ in.[/tex]
Thus, the height of Ron's tower is more than Freddy's tower by [tex]30\ in.[/tex]
The radius of a circle is 8 units.
What is the diameter of the circle?
units
Answer:
16
Step-by-step explanation:
radius is 1/2 of diameter
Answer:
16 units
Step-by-step explanation:
When a circle is inscribed in a square, the length of each side of the square is equal to the diameter of the circle. That is, the diameter of the inscribed circle is 8 units and therefore the radius is 4 units.

We are painting a rectangular wall of a large room. The dimensions of the wall are 35feet long and 21.5 feet wide. If the total cost of the paint was 421.40 what was the cost in dollars of the paint rounded to the nearest cent
Answer:
56 cent per ft²
Step-by-step explanation:
Wall dimension = 35 feets * 21.5 feets
Total cost of paint used = 421.40
Area of wall = Area of rectangle = Length * width
Area of wall = 35 feets * 21.5 feets
Area of wall = 752.5 ft²
Cost of paint per square feet:
Total coast of paint / Area of wall
$421.40 / 752.5 ft²
= $0.56 per ft²
= 0.56 * 100 = 56

Step-by-step explanation:
Find the value of x. Then find the measure of each interior angle. Show work algebraically
Answer:
Step-by-step explanation:
W=180-144
W=36 degrees
The sum of angles in a triangle always sum to 180 degrees.
6x+1+7x+36=180
13x+37=180
13x=143
x=11
U=6x+1
U=6(11)+1=67 degrees
V=7x
V=7(11)=77 degrees so
x=11 degrees, U=67 degrees, V=77 degrees, and W=36 degrees.

You deposited $10,000 into a savings account that compounds quarterly. The account has an interest rate of 3%. What would be the value after 30 years?
Answer:
$24272.62
Step-by-step explanation:
Given data
Principal= $10,000
Rate= 3%
Time = 30 years
The expression for the compound interest is given as
A= P(1+r)^t
Substitute
A=10000(1+0.03)^30
A=10000(1.03)^30
A=10000*2.4272
A= 24272.62
Hence the final Amount A=$24272.62

State if the triangles in each pair are similar. If so, complete the similarity statement.
Answer:
B
Step-by-step explanation:
Set up a proportion and see if it is true:
[tex]\frac{12}{8} =\frac{27}{18} \\\frac{3}{2} =\frac{3}{2}[/tex]
True, so they are similar.
The similarity statement would be QRS ~ QED

Part A: Let y represent the number of rabbits after x years. Which functioncan be used to model y as a function of x, where x is a non negative number ?
А. y = 10 (3) ^ (x - 1)
В. y = 10 (3) ^ x
C. y = 3 (10) ^ (x - 1)
D . y = 3 (10) ^ x
Answer:
y = 10(3)x
Step-by-step explanation:
The exponential function that can represent the population of rabbits after [x] years is y = 10(3)ˣ.
What do you mean by domain and range of a function?For any function y = f(x), Domain is the set of all possible values of [x] for which [y] exists. Range is the set of all values of [y] that exists for the given domain.
Given is rate of increase of a rabbit's population.
The exponential function that can represent the population of rabbits after [x] years can be written as -
y = 10(3)ˣ
Refer to the graph attached.
Hence, the exponential function that can represent the population of rabbits after [x] years is y = 10(3)ˣ.
