2. In a truck of red and green peppers, the ratio of red peppers to green peppers is 3.4.
If the truck contains 120 green peppers, how many red peppers are there?
Answers
Answer:
90
Step-by-step explanation:
3:4
R:G
total ratio =7
total peppers is y
4/7 × y = 120
7×120=4y
840÷4=y
y=210
G+R=Y
210-120=R
R=90
. Shawn gets an allowance of $18 each week and his sister Natasha gets an allowance of $9 each week. Shawn saves 1/2 of his allowance, and Natasha saves 2/3 of her allowance. Suppose Shawn started with $0 savings, and Natasha started with $30. How many weeks will it take until they have the same amount in savings?
Answers
Answer:
Shawn and Natasha have same amount in savings after [tex]10[/tex] weeks.
Step-by-step explanation:
Shawn gets an allowance of $18 each week.
Amount saved by Shawn = [tex]\frac{1}{2}(\$18)=\$9[/tex]
Natasha gets an allowance of $9 each week.
Amount saved by Natasha = [tex]\frac{2}{3}(\$9)=\$6[/tex]
Suppose that Shawn and Natasha have same amount in savings after [tex]x[/tex] weeks.
Also, Shawn started with $0 savings, and Natasha started with $30.
So,
[tex]9x=30+6x\\9x-6x=30\\3x=30\\x=10[/tex]
Therefore,
Shawn and Natasha have same amount in savings after [tex]10[/tex] weeks.
Ted has the following triangle dimensions.
side length of 8
side length of 14
side length of 23
How many triangles can he construct?
He can construct only one triangle.
He can construct two triangles.
He can construct three triangles.
He cannot construct a triangle.
Answers
Answer:
He cannot construct a triangle
Step-by-step explanation:
In order to construct a triangle the two shorter sides added together have to be greater than the longest side if that makes sense
So basically 8+14 has to be greater than 23 in order for it to be side lengths of a triangle
8+14=22
22 is not greater than 23 therefore he cannot create a triangle

Find the volume of a pyramid with a square base, where the perimeter of the base is
17 cm and the height of the pyramid is 15 cm. Round your answer to the nearest
tenth of a cubic centimeter.
Answers
Answer:
90.3125 cm³
Step-by-step explanation:
Since the perimeter of the bottom square is 17, you can divide by four to find out what the lenght of each side is.
17/4=4.25 cm
We know the height of pyramid is 15 cm
The formula for the volume of a square pyramid is
V=a²(h/3)
V=a2(h/3)=4.252·15/3=90.3125 cm³

What is x equal to in this problem?
Answers
Answer: x = 6
Step-by-step explanation:
All angles in a triangle = 180*
9x - 11 + 80 + 57 = 180
9x + 137 = 180
9x = 54
x = 6
Plug in to see if its correct
9 (6) - 11 + 80 + 57 = 180
54 + 126 = 180
180 = 180

b. Function: Yes
Domain = All positive integers
Range = All positive integers
c. Function: The relation is not a function
Step-by-step explanation:
A function is a relation where each input value has only one output value
a. The given data are presented as follows
[tex]\begin{array}{cc}Width \, (m)&Area \, (m^2)\\1&9\\5&50\\10&150\\11&176\\14&266\end{array}[/tex]
For each value of the input variable, the width, there is exactly one out put variable, therefore, the relation is a function
Function; Yes
The domain, the input values, includes; 1, 5, 10, 11, 14
The range, the output, values, includes; 6, 50, 150, 176, 266
b. Hours worked versus salary
[tex]\begin{array}{cc}Hours \ worked &Salary\\0&0\\10&\$300\\20&\$600\\30&\$900\\40&\$1200\end{array}[/tex]
For each value of the input variable, hours worked, there is exactly one out put variable, therefore, the relation is a function with the following equation;
Salary = $30 × Hours worked
Function; Yes
The domain, the input values, includes; All positive integers
The range, the output, values, includes; All positive integers
c. Height versus age
[tex]\begin{array}{cc}Height \, (cm)&Age\, (years)\\160&20\\160&25\\160&30\\160&35\\160&40\end{array}[/tex]
For each value of the input variable, the height, there are more than one out put variable, the age, therefore, the relation is not a function
Function; No

Answers
Answer:
∠NOP = 53°
Step-by-step explanation:
According to exterior angle theorem,
In a triangle, an exterior angle is equal to the sum of the two opposite interior angles.
∠NOP = ∠MNO + ∠OMN
Put ∠NOP = ( 7x - 17)°, ∠MNO = (x + 20)° and ∠OMN = (3x - 7)°
[tex]7x-17=x+20+3x-7\\7x-17=4x+13\\7x-4x=13+17\\3x=30\\x=10[/tex]
Therefore,
∠NOP = ( 7(10) - 17)° = (70 - 17)° = 53°

You can easily calculate that each of the sides have the length:
AB= BC = CD = AD = [tex]\sqrt{1^2+4^2} = \sqrt{17}[/tex]Parallel sides have equal slopes:
m = - 4 for AB and CDm = - 1/4 for AD and BCDiagonals are perpendicular as their slopes are negative reciprocal:
m = 1 for ACm = -1 for BDSo we see the quadrilateral ABCD has two pairs of parallel sides, all sides are equal and the diagonals are perpendicular.

Identify the solution set of 3 In 4 = 2 In x.
o {6}
O {-8, 8}
o {8}
DONE
(8)
Answers
Answer:
Step-by-step explanation:
3ln(4) = 2ln(x)
ln(4³) = ln(x²)
4³ = x²
(2²)³ = x²
2⁶ = x²
x = ±√2⁶ = ±2³ = ±8
However, the argument of a logarithm must be positive, so x=8.
The solution set of the equation is {8, -8}, but we can discard the negative solution as it is not physically meaningful in this context. So, the final solution set is {8}. Option D is correct.
To solve the equation, we can use the logarithmic identity that states:
n * log(a) = log(aⁿ)
Using this identity, we can rewrite the equation as:
In(4³) = In(x²)
Simplifying both sides using the natural logarithm properties, we get:
In(64) = In(x²)
Taking the exponential of both sides, we have:
[tex]e^{In 64} = e^{In x^2}\\64 = x^2[/tex]
Taking the square root of both sides, we get:
x = ±8
However, we must check if either of these solutions makes the argument of the natural logarithm negative, which is not allowed. Since the argument of the natural logarithm is positive for both x = 8 and x = -8, both solutions are valid.
Therefore, the solution set of the equation is {8, -8}, but we can discard the negative solution as it is not physically meaningful in this context. So, the final solution set is {8}.
