Final answer:
The painter charged $615 for a job that took 15 hours and required 3 cans of paint, which is answer choice (c).
Explanation:
To calculate the total charge for a painting job that took 15 hours and used 3 cans of paint, we need to plug these values into the painter's pricing formula, 35h + 30c.
Substituting the given values into the equation, we get:
Total charge = 35(15) + 30(3)
Total charge = 525 + 90
Total charge = $615
Therefore, the painter charged $615 for the job, which corresponds to answer choice (c).
A shipping clerk will ship an order of 200 batteries so long as three randomly selected batteries work. Past data has shown that five out of 200 batteries are defective. What is the probability that the clerk will ship the order?
Answer:
0.9264999239
Step-by-step explanation:
chance that first battery that is being checked works is 195/200
chance that second battery that is being checked works is 194/199
chance that third battery that is being checked works is 193/198
propabilty that the clerk ships the order is (195/200)×(194/199)×(193/198)
=0.9264999239
There are 4 blueberry, 6 raisins, and 2 plain bagels in a bag. Mike randomly selects two bagels without replacing the first bagel. Find the probability that he selects a raisin bagel and then a plain bagel
Answer:
The probability that he selects a raisin bagel and then a plain bagel is [tex]\frac1{11}[/tex].
Step-by-step explanation:
Probability:
The ratio of the number of outcomes of favorable event to total number of all possible outcomes is called probability of the favorable event.
[tex]Probability=\frac{\textrm{The number of favorable outcomes}}{\textrm{Total number of all possible}}[/tex]
Given that, there are 4 blueberry, 6 raisins and 2 plain bangles in a bag.
Total number of bangles= (4+6+2)
= 12
The probability that he selects a raisin
[tex]=\frac{\textrm{Number of raisin bangles}}{\textrm{Total number of bangles}}[/tex]
[tex]=\frac{6}{12}[/tex]
[tex]=\frac12[/tex]
Total number of remaining bagels is =(12-1)=11
After selecting a raisin bagel,the probability that he selects a plain bangle is
[tex]=\frac{\textrm{Number of plain bangles}}{\textrm{Total number of bangles}}[/tex]
[tex]=\frac{2}{11}[/tex]
Selecting of a raisin bangle and a plain bangle are both independent event.
The probability that he selects a raisin bagel and then a plain bagel is
[tex]=\frac{1}2\times\frac{2}{11}[/tex]
[tex]=\frac1{11}[/tex]
Mr. Ishimoto needs to replace the grass in the section of his lawn that is shown below.
A grass section can be broken into 2 rectangles. 1 rectangle has a base of 7 feet and height of 3 feet. The other rectangle has a base of 2 feet and height of 7 feet.
If the new grass costs $0.40 per square foot, how much will the grass cost Mr. Ishimoto?
$14.00
$16.40
$35.00
$41.00
Answer:
The replacing the grass will cost Mr. Ishimoto $14.00.
Step-by-step explanation:
The area of a rectangular field is:
[tex]\text{Area}=\text{height}\times \text{base}[/tex]
It is provided that Mr. Ishimoto needs to replace the grass in the section of his lawn.
The grass section can be broken into 2 rectangles.
First rectangle: Base = 7 feet and Height = 3 feet.
Second rectangle: Base = 2 feet and Height = 7 feet.
Compute the area of both the rectangles as follows:
[tex]\text{Area}_{1}=\text{height}_{1}\times \text{base}_{1}\\=3\times 7\\=21[/tex] [tex]\text{Area}_{2}=\text{height}_{2}\times \text{base}_{2}\\=7\times 2\\=14[/tex]
Now the cost of the new grass is $0.40 per square foot.
Compute the cost of replacing the grass in the first rectangular section as follows:
[tex]\text{Cost of new grass for section 1}=\text{Area}_{1} \times\$0.40\\[/tex]
[tex]=21\times \$0.40\\=\$8.40[/tex]
Compute the cost of replacing the grass in the second rectangular section as follows:
[tex]\text{Cost of new grass for section 2}=\text{Area}_{2} \times\$0.40\\[/tex]
[tex]=14\times \$0.40\\=\$5.60[/tex]
The total cost of replacing the grass is:
[tex]\text{Total cost}=\text{Cost of new grass for section 1}+\text{Cost of new grass for section 2}[/tex]
[tex]=\$8.40+\$5.60\\=\$14.00[/tex]
Thus, the replacing the grass will cost Mr. Ishimoto $14.00.

What is 19+11+77-2/10? for math points
Answer: 19 + 11 = 30 + 77 = 107 - 2/10 = 106.8
If you're confused by the fraction just do 2 divided by 10 and you should get 0.2.
So, instead of doing 2/10 you can do:
19 + 11 = 30 + 77 = 107 - 0.2 = 106.8

Answer:
Grows, Factor of 2
Step-by-step explanation:
The relationship between the elapsed time, t, in years, since Takumi started studying his tree, and the total number of its branches, N(t), is modeled by the function:
[tex]N(t) = 63. 2^t[/tex]
For illustration, let us take the growth for the first three years after he started studying the number of branches.
[tex]When \:t=1, N(1) = 63. 2^1=126\\When \:t=2, N(2) = 63. 2^2=252\\When \:t=3, N(3) = 63. 2^3=504\\504\div 252=252\div 126=2[/tex]
We notice that for each subsequent year, the number of branches doubles.
Therefore:
Every year, the number of branches grows by a factor of 2.

Tickets to the school dance cost $3.00 in advance or $5.00 at the
door. There were a total of 184 tickets sold, raising $688. How many tickets
were sold at the door?
Answer:
68 tickets
Step-by-step explanation:
This is a problem that involves a system of equations, the first step is to define your variables and write equations to represent the situation.
x = number of advance tickets
y = number of door tickets
x + y = 184
3x + 5y = 688
Next, you need to solve for one variable, based on how these equations are written, the best method would be to solve by multiplication.
-3(x + y = 184) (multiply equation by -3)
-3x - 3y = -552
Now we need to combine the two equations together
3x + 5y = 688
-3x - 3y = -552
From here we can eliminate the x variable when subtracting the equations, this results in:
2 y = 136
y = 68
Therefore, 68 tickets were sold at the door.

Answer:
x = 12[tex]\sqrt{2}[/tex]
y = 12
z = 12[tex]\sqrt{3}[/tex]
Step-by-step explanation:
The triangle with z as one of it's sides is a 30, 60, 90 triangle where the longest side of the triangle is 2x, the shortest side as x, and the middle side as x*sqrt of 3.
The shared line between the two triangle is 12 and z is 12*sqrt of 3
The left triangle is a 45, 45, 90 triangle where the 2 sides that look the same are the same and the hypotenuse is x sqrt of 2 so y is 12 and x is 12 sqrt of 2
Answer:
x = [tex]12\sqrt{2}[/tex] units
y = 12 units
z = [tex]12\sqrt{3}[/tex] units
Step-by-step explanation:
Notice that the biggest triangle is broken up into a 45-45-90 isosceles triangle with hypotenuse x and leg y, as well as a 30-60-90 triangle with hypotenuse 24 and long leg z.
Let's focus on finding z first. Remember that in a 30-60-90 triangle, the ratio of the short leg to the long leg to the hypotenuse is: [tex]1:\sqrt{3} :2[/tex]. Here, the hypotenuse is 24 and z is the longest leg, so we have the proportion:
[tex]\frac{\sqrt{3} }{2} =\frac{z}{24}[/tex]
Cross-multiply:
[tex]24\sqrt{3} =2z[/tex]
z = [tex]12\sqrt{3}[/tex] units
Now, let's find the smallest leg of the 30-60-90 triangle; it is simply 24/2 = 12 units. Let's move onto x and y.
Remember that in a 45-45-90 triangle, the ratio of one leg to the second leg to the hypotenuse is: [tex]1:1:\sqrt{2}[/tex]. So, since y is a leg of this triangle and the smallest leg of the 30-60-90 triangle coincides with the second leg of the 45-45-90 triangle, y = 12 units.
Finally, x is found by multiplying 12 by [tex]\sqrt{2}[/tex]: 12 * [tex]\sqrt{2}[/tex] = [tex]12\sqrt{2}[/tex] units

True or false: y=x3−4 is a linear equation. A true B false
false because it is formed wrong
Final answer:
The equation y = x^3 - 4 is not a linear equation because it contains a cubic term (x^3), which means the graph is a curve, not a straight line. Therefore, the correct answer is false.
Explanation:
The equation y = x3 − 4 is not a linear equation. A linear equation is one in which every term is either a constant or the product of a constant and the first power of a variable. In the given equation, the term x3 indicates that it is a cubic term because the value of x is raised to the power of three, suggesting that the graph of this equation would be a curve, not a straight line. Therefore, the correct answer is false.
Linear equations have the general form y = mx + b, where 'm' is the slope and 'b' is the y-intercept. Examples of linear equations include y = −3x, y = 0.2 + 0.74x, and y = −9.4 − 2x, which can all be graphed as straight lines. In contrast, an equation like y = x3 − 4 does not fit this form and therefore is not considered linear.
