Answer:
57°
Step-by-step explanation:
ALL angles in a triangle add up to 180°
SO, if we know the sum of two angles which is 123° (why: 33+90=123), all we have to do is subtract this number from 180 to get the measure of the 3rd angle. Which in this case is 57°
The measure of angle B will be 57° for the given triangle.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
There are many types of triangles such that right angle triangle, equilateral triangle, and much more.
The sum of all three interior angles of any triangle is 180°.
So,
A + B + C = 180°
Given,
A = 33° and C = 90°
33° + B + 90° = 180°
B = 180 - (90 + 33)
B = 180° - 123°
B = 57°
Hence, The measure of angle B will be 57° for the given triangle.

A: 12%
B: 30%
C: 60%
D: 100%
It's C that's correct!
Since there's a total of 30 strawberries and Yuki ate 12 strawberries, there will be 18 strawberries left.
To find the percentage of the amount that remained:
18/30 × 100 = 60%
Therefore the correct option is A

You start driving north for 32 miles, turn right, and drive east for another 24 miles.
How many miles must you travel to return directly back to your starting point?
Answer:
40 miles
Step-by-step explanation:
You can recognize the right triangle as a 3-4-5 right triangle with a scale factor of 8. So the length of the hypotenuse is 8·5 = 40 miles.
___
Or, you can use the Pythagorean Theorem, which tells you that the sum of the squares of the leg distances will equal the square of the straight-line (hypotenuse) distance:
32² + 24² = h²
1024 +576 = h² = 1600
h = √1600 = 40 . . . . miles
Carl and Laura are reading different copies of the same book. Carl has already read 10 pages of his copy of the book when Laura begins reading her copy of the book. A system of equations can be used to compare the number of pages (y) each person has read x minutes after Laura begins reading her copy of the book. The solution to the system of equations is (40, 50). What does the solution (40, 50) represent in this situation?
a.)Carl and Laura have both read 50 pages after Laura has been reading for 40 minutes.
b.)Carl has read 50 pages and Laura has read 40 pages.
c.)Carl has read 40 pages and Laura has read 50 pages.
d.)Carl and Laura have both read 40 pages after Laura has been reading for 50 minutes.
Final answer:
The solution (40, 50) to the system of equations indicates that after 40 minutes, Laura has read 40 pages and Carl, with a head start, has read a total of 50 pages, option D.
Explanation:
The solution to the system of equations (40, 50) represents the amount of time Laura has spent reading and the number of pages both Carl and Laura have read. In this context, 'x' represents the number of minutes Laura has been reading her copy of the book, and 'y' represents the number of pages each person has read. Therefore, the solution (40, 50) means that after Laura has been reading for 40 minutes, Laura has read 40 pages, and Carl, who had a 10-page head start, has read a total of 50 pages.

A recipe calls for 2/3 cup of flour for every 4 teaspoons of vanilla. How much vanilla should be used for every 1 cups of flour?
A. 1/6
B. 2 2/3
C. 4 2/3
D. 6
Please help and explain everything! Thanks!
Answer: For 1 cup of flour, there should be 6 teaspoons of vanilla.
Step-by-step explanation:
What I did is that I found what 1 ÷ 2/3 equals. To find that, I used the reciprocal so the new equation would be 1 × 3/2 which equals 3/2. So since 2/3 × 3/2 equals 1, we have to do the same to 4 teaspoons. 4 × 3/2 equals 6. Therefore, there should be 6 teaspoons of vanilla for every one cup of flour.

Write the following equation in slope intercept:
2x + 3y = 12
Y = mx + b
2x + 3y = 12
3y = -2x + 12
y = -2/3 + 4
Answer:
y = -2/3x +4
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
2x+3y = 12
We need to solve for y
Subtract 2x from each side
2x-2x+3y = -2x+12
3y = -2x+12
Divide by 3
3y/3 = -2/3 x +12/3
y = -2/3x +4

Find the solution of this system of equations. 3x+7y=46 -3x-8y=50
The solution to the system of equations 3x + 7y = 46 and -3x - 8y = 50 is x = 239.333... and y = -96. This can be verified by plugging these values back into the original equations.
Explanation:To find the solution of this system of equations, we can use the method of adding the two equations together, as they are set up nicely for elimination:
3x + 7y = 46-3x - 8y = 50Add the two equations together:
3x + 7y - 3x - 8y = 46 + 50
0x - y = 96
y = -96
Substitute y = -96 back into one of the original equations, for example the first equation:
3x + 7(-96) = 46
3x - 672 = 46
3x = 46 + 672
3x = 718
x = 718 / 3
x = 239.333...
The solution to the system is x = 239.333... and y = -96. We can verify the solutions by substituting back into the original equations.
Factor completely 3x3 − 6x2 − 24x. 3x(x − 4)(x + 2) 3x(x + 4)(x − 2) 3x(x − 3)(x − 2) 3x(x + 3)(x − 2)
Answer:
3x(x - 4)(x + 2)
Step-by-step explanation:
Given
3x³ - 6x² - 24x ← factor out common factor of 3x from each term
= 3x(x² - 2x - 8) ← factor the quadratic
Consider the factors of the constant term (- 8) which sum to give the coefficient of the x- term.
The factors are - 4 and + 2, since
- 4 × 2 = - 8 and - 4 + 2 = - 2, thus
x² - 2x - 8 = (x - 4)(x + 2) and
3x³ - 6x² - 24x = 3x(x - 4)(x + 2)

3x(x - 4)(x + 2)

What size picture will result when a 5 in. • 7 in. Picture is reduced using an 80% setting?
A 5" * 7" image reduced by 20% in scale to 80% of the original size will be 4" * 5.6". Roughly the size of a large flash card.
When a 5 inch by 7 inch picture is reduced using an 80% setting, the new dimensions will be 4 inches by 5.6 inches.
To calculate the new size of a 5 inch by 7 inch picture when reduced by 80%, we simply multiply both dimensions by the reduction percentage. Hence, the width and the height of the picture will be reduced to 80% of their original size.
Original width: 5 inches
Original height: 7 inches
Reduction setting: 80% (or 0.8)
New width: 5 inches × 0.8 = 4 inches
New height: 7 inches × 0.8 = 5.6 inches
Therefore, the new dimensions of the picture will be 4 inches by 5.6 inches after an 80% reduction.
The total area of two rectangles can be represented by the expression (x)(3x+1) + (2x)(x+3). Which expression represents the total area of the two rectangles?
Answer:
The total area of the two rectangles is [tex](5x^{2} +7x)\ units^{2}[/tex]
Step-by-step explanation:
Area of rectangle 1
[tex](x)(3x+1)=(3x^{2} +x)\ units^{2}[/tex]
Area of rectangle 2
[tex](2x)(x+3)=(2x^{2} +6x)\ units^{2}[/tex]
therefore
The total area of the two rectangles is equal to
[tex](3x^{2} +x)\ units^{2}+(2x^{2} +6x)\ units^{2}=(5x^{2} +7x)\ units^{2}[/tex]
The correct choice is [tex]5x^{2} +7x[/tex]. By expanding and combining the terms, the total area of the two rectangles is represented by the expression found.
Let's first expand each term in the expression (x)(3x+1) + (2x)(x+3) to determine the total area of the two rectangles:
(x)(3x+1) = [tex]3x^{2} +x[/tex](2x)(x+3) = [tex]2x^{2} +6x[/tex]Now, add the two results together:
[tex]3x^{2}[/tex] + x + [tex]2x^{2}[/tex] + 6x = [tex]5x^{2} +7x[/tex]Therefore, the expression that represents the total area of the two rectangles is [tex]5x^{2} +7x\\[/tex] .

You run 5 miles in 1 hour. At this rate, how long will it take you to run a marathon (approximately 26 miles)?
I got 5 hours and 2 minutes and I'm not sure if I'm correct.
Answer:
5 hours 12 mins
Step-by-step explanation:
You run 5 miles in 1 hour.
5 miles = 1 hour
1 mile = 1 ÷ 5 = 0.2 hour
1 mile = 0.2 hour
26 miles = 0.2 x 26 = 5.2 hours
5.2 hours = 5 hours + (0.2 x 60) mins
5.2 hours = 5 hours 12 mins
If the speed is 5 miles per hour. Then the time taken to complete marathon of 26 miles will be 5 hours and 12 minutes.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
You run 5 miles in 1 hour.
Then the speed will be
Speed = 5/1
Speed = 5 miles per hour
Then the time taken to complete marathon of 26 miles will be
Time = Distance / Speed
Time = 26 / 5
Time = 5.2 hours
The time 5.2 hours can be written as 5 hours and 12 minutes.
More about the speed link is given below.

Solve the inequality -x/2 ≤ 1. Let's eliminate the fraction first, by multiplying both sides by 2:

We want to solve for +x, not for -x.
Therefore, divide both sides of this latest inequality by -1, remembering to reverse the direction of the inequality sign:
