Answer: y=1/4+3
Step-by-step explanation:
1. The slope is 12
2. (6 - 2)/(12+4)= 4/16= 1/4
y - 2 = 1/4(x + 4)
y - 2 = 1/4x + 1
y = 1/4x + 3

A box in the shape of a rectangular prism, with dimensions 12 inches by 18 inches by 12 inches, can hold exactly 12 cubes measuring 6 inches on each side.
If the length and width of the base are doubled, how many cubes could the new box hold?
18
24
48
96
Answer: 48 cubes in the new box
Step-by-step explanation:
Doubling the length and the width is 2×2, so 4 times the original capacity.
4×12 = 48
It is not necessary to compute the volume. The dimensions could be anything. It's the number of cubes that count.
Answer:
C, 48

Which value of x makes the equation true?
0
-5.3
O - 4.1
O 4.1
O 5.3
Answer:
5.3
Step-by-step explanation:
1.8x = 9.4
x = 5.3
The value of x that makes the equation true is 5.3, the correct option is D.
What is an Equation?An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.
The equations are useful in determination of unknown parameters.
The equation is,
0.3x + 5. 14 = 2.1x - 4.4
The equation is made of two expressions,
The expression 1 is : 0.3x + 5. 14
The expression 2 is : 2.1x - 4.4
The value of x that makes the equation true has to be determined.
0.3x + 5. 14 = 2.1x - 4.4
Grouping the like terms on one side.
5.14 +4.4 = 2.1x -0.3x
Solving the variables and constants
9.54 = 1.8 x
Dividing 1.8 on both sides of the equation.
x = 9.54 /1.8
x = 5.3
The value of x at which the equation is true is 5.3.

What is the slope of a line perpendicular to the line whose equation is
15x + 12y = -144. Fully reduce your answer.
Step-by-step explanation:
Hey there!
Let the unknown slope be M2.
The given equation is;
15x + 12y = -144
From equation;
[tex]slope( m) = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]
[tex]m = \frac{ - 15}{12} [/tex]
[tex]m = \frac{ - 5}{4} [/tex]
For the condition of perpendicular lines;
[tex]m \times m2 = - 1[/tex]
[tex] \frac{ - 5}{4} \times m2 = - 1[/tex]
[tex] - 5m2 = - 4[/tex]
[tex]m2 = \frac{ - 4}{ - 5} [/tex]
Therefore, the slope is 4/5.

Enter decimal numbers in the boxes to identify the point in Quadrant III which is 3 units away from point A.
Answer:
(-0.5, -0.5)
Step-by-step explanation:
Let the coordinates of the point P in quadrant 3 are (x, y).
If a point A is 3 units apart, coordinates of point P will be [(x - 3), y].
From the figure attached,
Coordinates of the point A are (2.5, -0.5).
x coordinate of point P → (2.5 - 3) = -0.5
y coordinate of the point P → (-0.5) = -0.5
Therefore, point P which is 3 units apart from A will be (-0.5, -0.5)
Answer:
0.5,0.5

Answer:
$9.68
Step-by-step explanation:
The total cost before tax is $75.50 + $12.50 = $88
11% of $88 = 0.11 * $88 = $9.68
Answer: $9.68
Answer:
Step-by-step explanation:
$75.50 (bike) + $12.50 (helmet) = $88 (this is the amount shawn will pay before tax

Find the first of three consecutive even integers if the sum of the first and second is 15 less than 3 times the third.
Answer:
First even integer: 6
Step-by-step explanation:
Inequalities
Assume x is the first even integer. The next integer is x+2, and the last integer ix x+4.
The condition states that the sum of the first and the second number is 15 less than three times the third. This takes us to the inequality:
[tex]x+x+2<3(x+4)-15[/tex]
Operating:
[tex]2x+2<3x+12-15[/tex]
Subtracting 2 and 2x:
[tex]0<3x+12-15-2x-2[/tex]
Simplifying:
[tex]0<x-5[/tex]
Solving:
x>5
There are infinitely many solutions. For example, for x=6 (first even number into the solution interval):
First integer: 6
Second integer: 8
Third integer: 10
There are other solutions, like 20,22,24 but the first set is 6,8,10.

A bag contains 12 red marbles the ratio of red marbles to blue marbles is 3:4 find the number of blue marbles in the bag
Answer:
16
Step-by-step explanation:
If the ratio is 3 red marbles to 4 blue marbles we can solve this using the following:
[tex]\frac{12}{b} = \frac{3}{4}[/tex]
[tex]12 * 4 = 3b\\48 = 3b\\\frac{48}{3} = b\\b = 16[/tex]
So we have 16 blue marbles.
Based on the ratio of red to blue marbles, the number of blue marbles in the bag is 16 marbles.
The bag has red marbles to blue marbles in a ratio of 3:4.
If there are 12 red marbles, the number of blue marbles can be found by direct proportion:
3 : 4
12 : x
Cross-multiply:
3x = 48
x = 48/3
x = 16 blue marbles
In conclusion, there are 16 blue marbles in the bag.

You operate a fresh fruit and vegetable market. For normal shipments, about 9.0% of the peaches are spoiled when they reached your market. You anticipate a busy weekend and would like to have 100 pounds of peaches to sell. To have 100 pounds of peaches and considering the spoilage rate, how many pounds should you order? A. 101 lbs. B. 105 lbs. C. 109 lbs. D. 110 lbs. E. 112 lbs.
Given:
Spoilage rate of fruits = 9% = 0.09
To find:
Amount of fruits to be order to have 100 pounds of peaches and considering the spoilage rate.
Solution:
Let the required amount of fruits you should order be x.
So, spoiled fruits = 9% of x = 0.09x
He would like to have 100 pounds of peaches to sell.
[tex]x-0.09x=100[/tex]
[tex]0.91x=100[/tex]
Divide both sides by 0.91.
[tex]x=\dfrac{100}{0.91}[/tex]
[tex]x=109.89[/tex]
[tex]x\approx 110[/tex]
The required amount of fruits to be order is 110 lbs. Therefore, the correct option is D.

From 1995 - 2008 in the US 648 people were struck by lightening. 531 of them were men. You want to see if this observation differs from the null hypothesis, that 50% of people who are hit by lightening would be men, based on the proportion of men in the population as a whole. Calculate the probability under the normal distribution of getting a result of 531 or more (including the continuity correction). Use the binomial test with a normal approximation. What is your conclusion?
Answer:
Because z is higher than any given value in the chart we come to the conclusion To reject null hypothesis
Step-by-step explanation:
Sample proportion = p= 531/648 = 0.8194
This is the proportion of men that were hit by lightening
Null hypothesis: H0: p = 0.5
Alternate hypothesis: H1: p ≠ 0.5
Test statistics z = 0.8194-0.5/(√0.5x0.5/648)
= 0.8194-0.5/√0.0003858
= 0.3194/0.019642
= 16.26
Since the z > 1.96 (at 5% significance) we reject the null hypothesis.
Therefore in conclusion we say z is higher than given values in the chart so we reject null hypothesis.
