Answer:
12
Step-by-step explanation:
No of tulips = 60
No of daffodils = 72
We need to find the greatest number of bouquets the florist can make if the florist will make bouquets with the same number of tulips and the same number of daffodils in each using all the flowers.
It would mean that we need to find the HCF of 60 and 72
Prime factorisation of 60 = 2×2×3×5
Prime factorization of 72 = 2 x 2 x 2 x 3 x 3
Highest common factor or HCF = 2×2×3 = 12
So, the florist can make 12 bouquets as maximum number.
three angles are adjacent to each other and form 140.the largest angle is twice the smaller angle and the angle which is middle size is 24 more than the smallest. find the angles
Answer:
Smallest: 29, Middle: 53, Largest: 58
Step-by-step explanation:
We can represent the angles in this problem using an equation.
We'll use x to represent the smallest angle, and work out other ways to represent the others.
As the largest angle is twice that of the smaller angle, we can represent the largest angle as 2x as 2x is two times x.
The middle angle is 24 more than the smallest, so we can represent that one as x + 24, since it is 24 more than the smallest.
Now we have our angles all represented with x:
Smallest angle = x
Middle = x+24
Largest = 2x
We know that they all add together to 140 so our equation is:
x+2x+(x+24) = 140
Now we can solve for x!
We can remove the brackets (addition does not change the terms) and combine the terms:
x+2x+x+24=140
4x+24=140
Next we move the 24 to the other side so we can solve for x:
4x + 24 - 24 = 140 - 24
4x = 116
Finally we divide both sides by 4:
x=29
The smallest angle is 29!
Now we can use our representations to find the other angles:
Middle angle = x+24, therefore it is 29+24 = 53
Largest angle = 2x therefore it is 2*29 = 58
58+53+29=140 so we have successfully worked out our angles!
Hope this helped!

Answer:
a). f(0) = 7
b). f([tex]\frac{1}{3}[/tex]) = 6
c). f(-5) = 22
d). x = 9
Step-by-step explanation:
The given function is f(x) = -3x + 7
a). For x = 0
f(0) = -3(0) + 7
= 0 + 7
= 7
b). For x = [tex]\frac{1}{3}[/tex]
f([tex]\frac{1}{3}[/tex]) = [tex](-3)(\frac{1}{3})+7[/tex]
= -1 + 7
= 6
c). For x = (-5)
f(-5) = -3(-5) + 7
= 15 + 7
= 22
d). For f(x) = (-20)
-20 = -3x + 7
3x = 20 + 7
3x = 27
x = 9

Solve (2^2x+1)-9(2^x)+4=0
x₁ = - 1
x₂ = 2
Step-by-step explanation:2²ˣ⁺¹ - 9ₓ2ˣ + 4 = 0
2²ˣₓ2 - 9ₓ2ˣ + 4 = 0
2ˣ = n
2n² - 9n + 4 = 0
2n² - n - 8n + 4 = 0
n(2n - 1) - 4(2n - 1) = 0
(2n - 1)(n -4) = 0
2n - 1 = 0 => n₁ = 1/2
n - 4 = 0 => n₂ = 4
2ˣ = 1/2 => 2ˣ = 2⁻¹ => x₁ = - 1
2ˣ = 4 => 2ˣ = 2² => x₂ = 2

One side of a triangle is 8 feet longer than the second side. The third side is 4 feet longer than the second side. The perimeter of a triangle is 36 feet. Find the length of each side.
Answer:
The second side is 8.
The third side is 12.
The last side is 16.
Step-by-step explanation:
The third side is 12 because it is 8+4. Given these facts, it is 20 feet so far. And the last side of the triangle is 16, for it is 8+8. So, 16+20 is 36. Hope thsi helped.

Use the following information to answer questions .
A purchasing unit for a state government has found that 60% of the winning bids for office- Cleaning contracts come from regular bidders, 30% from occasional bidders, and 10% from first- uime bidders. The services provided by successful bidders are rated satisfactory or unsatisfactory anter one year on the job. Experience indicates that 90% of the jobs done by regular bidders are satisfactory, as are 80% of the jobs done by occasional bidders and 60% of the jobs done by first- time bidders.
1. What is the probability a job will be done by a first-time bidder and be satisfactory?
a. 0.06
b. 0.09
c. 0.10
d. 0.60
2. What is the probability that a job will be satisfactory?
a. 0.54
b. 0.60
c. 0.84
d. 0.95
3. Given that a job is satisfactory, what is the probability that it was done by a regular bidder?
a. 0.5778
b. 0.6141
c. 0.6429
d. 0.9000
Answer:
1
The correct option is A
2
The correct option is C
3
The correct option is C
Step-by-step explanation:
From the question we are told that
The proportion of the winning bid from a regular bidder is [tex]P(R) = 0.60[/tex]
The proportion of the winning bid from a occasional bidders is [tex]P(O) = 0.30[/tex]
The proportion of the winning bid from a first- time bidders is [tex]P(F) = 0.10[/tex]
The proportion of satisfactory jobs done by a regular bidders is [tex]P(R|S) = 0.90[/tex]
The proportion of satisfactory jobs done by a occasional bidders is [tex]P(O|S) = 0.80[/tex]
The proportion of satisfactory jobs done by a first- time bidders is [tex]P(F|S) = 0.60[/tex]
Generally the probability that a job will be done by a first-time bidder and be satisfactory is mathematically represented as
[tex]P(F n S) = P(F) * P(S|F)[/tex]
=> [tex]P(F n S) = 0.10 * 0.60[/tex]
=> [tex]P(F n S) = 0.060[/tex]
Generally the probability that a job will be satisfactory is mathematically represented as
[tex]P(S) = 0.60 * 0.90 + 0.30 *0.80+ 0.10*0.60[/tex]
=> [tex]P(S) = 0.84 [/tex]
Generally given that a job is satisfactory, what is the probability that it was done by a regular bidder is mathematically evaluated as
[tex]P( S | R) = \frac{0.90* 0.60}{0.60}[/tex]
[tex]P( S | R) = 0.6429[/tex]

The hypotenuse of a right triangle is 10 inches long. One of the legs is 2 inches longer than the other one. If x is the length of the shorter leg, what is the equation
Answer:
The equation is
X²+2x-48 = 0
Shorter one is 6 inches
Other side= 8 inches
Step-by-step explanation:
The equation for a right angle triangle normally is
A² = B² + C²
Where A = hypotenuse
Then B and C are the order sides of the triangle.
This time
Hypotenuse= 10 inches
The shorter one is X
While the other one is X+2
The equation
10²= x² +(x+2)²
100= x² + x² + 4x +4
100 - 4 = 2x² +4x
96= 2x² +4x
48 = x² +2x
X²+2x-48 = 0
Solving for x
X² +8x-6x-48= 0
X(x+8)-6(x+8)=0
(X-6)(x+8)= 0
X= 6 or x= -8
Definitely x is posiy
So x= 6
Shorter one is 6 inches
Other side= 6+2= 8 inches
The probability of rolling a number less than 3 on a number cube 2/6. Jennifer rolls a number cube 60 times how many times should jennifer except to roll a number less than 3
Answer:
20 times
Step-by-step explanation:
Given the following :
Probability of rolling a number less than 3 on a number cube:
Required outcome = (1, 2)
Total possible outcomes = (1, 2, 3, 4, 5, 6)
Required outcome / Total possible outcomes
= 2 /6
= 1/3
Hence, if number cube is rolled 60 times, number of times a number less than 3 is expected :
(Probability of obtaining a number less than 3 in one roll × number of rolls)
= (1 / 3) × 60
= 60 / 3
= 20 times
Subtract.

-3 3/8 - 7/8
Answer:
The answer is
[tex] - \frac{17}{4} \: \: or \: \: - 4 \frac{1}{4} [/tex]Step-by-step explanation:
[tex] - 3 \frac{3}{8} - \frac{7}{8} [/tex]First of all convert the mixed number to an improper fraction
We have
[tex] - 3 \frac{3}{8} = \frac{27}{8} [/tex]So we have
[tex] - \frac{27}{8} - \frac{7}{8} [/tex]Since they have the same denominator we can subtract them directly
We have
[tex] - \frac{27}{8} - \frac{7}{8} = - \frac{34}{8} [/tex]Reduce the fraction with 2
We have the final answer as
[tex] - \frac{17}{4} \: \: or \: \: - 4 \frac{1}{4} [/tex]Hope this helps you

[tex]a^-^2[/tex] is the same thing as 1/a². So, [tex]5^-^2[/tex] is 1/25. This is multiplied by 3² which is 9, so this is 9/25.
In the denominator, we have [tex]5^-^1[/tex], which is 1/5. We multiply this by 3, which is 3/5.
So, we divide 9/25 by 3/5, giving us 3/5.
Now, we raise this to the power of -2, so we flip the numerator and denominator and then square both numbers, giving us 25/9.
