timothy is planting a garden. Tulips cost $125 per bub. The total cost c of his gardening supplies is $1.25 per bub b plus $10 for a bag of mulch. What is the independent and dependent variables and the equation and solution!
Answer:
Independent variable = number of bub (b)
Dependent variable = total cost (c)
Equation: c = $1.25b + $10
Timothy would spend: $20
Step-by-step explanation:
Total cost = c
Number of bub = b
✔️Total cost, c, is dependent on the number of bub, b.
Therefore:
Independent variable = number of bub (b)
Dependent variable = total cost (c)
✔️Equation that describes this situation can be written as:
c = $1.25b + $10
✔️If Timorhy buys 8 bubs, he would spend the following:
Substitute b = 8 into c = $1.25b + $10, and solve for c.
c = $1.25(8) + $10
c = $10 + $10
c = $20

Alina has to spend $30 000 on expenses each year. If that amount of money is 40% of her total yearly earnings, then how much money does Alina make per year?
Answer:
$75000
Step-by-step explanation:
Given data
Let her yearly earnings be x
so
40% of x= $30000
40/100*x=30000
0.4x=30000
x=30000/0.4
=$75000
Hence the total amount made per years is
$75000

Step-by-step explanation:
The following examples to illustrate
[tex]\sqrt{2}[/tex] is irrational
[tex]\sqrt{2}[/tex] × [tex]\sqrt{2}[/tex] = 2 ← which is rational
[tex]\sqrt{3}[/tex] is irrational and
[tex]\sqrt{2}[/tex] × [tex]\sqrt{3}[/tex] = [tex]\sqrt{6}[/tex] ← which is irrational

I need to know the vertex of this parabola can someone help me ASAP
What is the Surface Area of the figure below?
A. 268 square inches
B. 134 square inches
C. 21 square inches
D. 240 square inches
Answer:
34.98 yds²
Step-by-step explanation:
To find surface area, we add together the area of each side. We have six sides, but there are three sets of identical sides, so it's easier to calculate.
We begin with the sides with dimensions 2.40 and 2.50. Multiply these together.
2.40 · 2.50 = 6
Since there are two of these sides, we can already say that the combined area of them is 12. So, we start the equation with 12.
Next, the two sides with dimensions 2.34 and 2.50. Multiply these together as well, to get 5.85. Multiply this by two to find the area of both sides, 11.7.
Add to our equation, for 12 + 11.7.
For the final two sides, we have the dimensions 2.34 and 2.40. Multiply to get 5.64. Multiply this again by two to find the area of both sides. We get 11.28. Add this to the equation as well, for 12 + 11.7 + 11.28= 34.98.
The answer is 34.98 yds². Good luck :)
The measures of the angles of a triangle are shown in figure below. Solve for x.
Answer:
Your answer will be 50
Step-by-step explanation:
First, add 62 + 68 to get 130.
Then, substract 130 by 180. Why? 180 HAS to be the total angle. 180 - 130 = 50
Therefore you have your answer.
Solve for x. The triangles in each pair are similar.

Jonathan is preparing for a triathlon he biked 3.5 miles on Thursday and 4.25 miles on Friday on Saturday he biked 12 miles how much farther did he bike on Saturday than he did on Thursday and Friday combined
Answer: 4.25 miles
Step-by-step explanation:
The distance he biked on Thursday and Friday combined is:
= 3.5 + 4.25
= 7.75 miles
On Saturday he biked 12 miles. The number of miles he biked over Thursday and Friday is:
= 12 - 7.75
= 4.25 miles
Which of the following is the correct order when multiplying two binomials?
Inner, first, last, outer
First, outer, inner, last
Outer, last, first, inner
Last, inner, outer, first
Please help.
Answer:
A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial.
Step-by-step explanation:
The correct order when multiplying two binomials will be First, outer, inner, and last. Then the correct option is B.
What is binomial?The binomial is a polynomial of two-term only. For example, x + 5 where x and 5 are two separate terms.
It is also known as the product. If the object n is given to m times then we just simply multiply them.
Let the two expressions are (a + b) and (c + d). Then the multiplication of the expressions will be given as,
⇒ (a + b) x (c + d)
⇒ a(c + d) + b(c + d)
⇒ ac + ad + bc + bd
The correct order when multiplying two binomials will be First, outer, inner, and last. Then the correct option is B.

Answer:
d
Step-by-step explanation:
[tex]x 1= \frac{ - b + \sqrt{ {b}^{2} - 4ac} }{2a} \\ x2 = \frac{ - b - \sqrt{ {b}^{2} - 4ac} }{2a} \\ x1 = \frac{ - 2 + \sqrt{ {2}^{2} - 4\times 1 \times ( - 3)} }{2} = 1 \\ x2 = \frac{ - 2 - \sqrt{ {2}^{2} - 4 \times 1 \times ( - 3)} }{2} = - 3[/tex]
Answer:
d
Step-by-step explanation:
Solving by factorising
Given
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1

A standardized test is designed so that scores have a mean of 50 and a standard deviation of 4.
What percent of scores are between 46 and 54?
Answer:
68.3%
Step-by-step explanation:
Using the relation :
Zscore = (x - Mean) / standard deviation
For, x between 46 and 54
Zscore = ((54 - 50) / 4) - ((46 - 50) / 4)
P(Z < 4/4) - P(Z < -4/4)
P(Z < 1) - P(Z <-1)
0.84134 - 0.15866
= 0.68268
= 0.68268 * 100%
= 68.3%
