write the equation of the line that passes through the point (0, 3) and is perpendicular.
please help me solve this :)
Answer:
y = 2x + 3
Step-by-step explanation:
to find the perpendicular line then you have to find the negative reciprocal which is 2 and to get that you flip the fraction and change the sign so
(-1/2) → 2/1 or 2
the y-intercept coordinate is (0, 3) so the y-intercept is 3
Slope of the Perpendicular line=2
passes through (0,3)Equation of line in point slope form

Terry calculates how much wood he needs to build the desk shown in the diagram . He says the area is 600ft2
What error did terry make
Find the correct area and explain your answer
Answer:
He forgot to multiply by 1/2 when finding the area of the above triangle.
Now we find the correct area;
A = BH x 1/2 (formula for finding area of triangle)
A = 10 x 24 x 1/2
A = 240 x 1/2
A = 240/2
A = 120
Now the rectangle's formula which is just (W x L) where "w" is the width and "l" is the length;
A = W x L
A = 24 x 15
A = 360
Now we add both the sums of the two areas:
120 + 360 = 480 square feet, the information provided here is your explanation.

For one particular homeroom, the typical ratio of students absent to students present is 1 : 14. One day, students from this same homeroom miss school to compete in a math competition. On that day, there are 22 students in class and the ratio of students absent to students present is 4 : 11. How many students are absent on a typical day for this homeroom?
Answer:
i THINK 43% but im not for sure
Step-by-step explanation:
14% of 50 is 7
so 50-7=43
43(percent there)+7(percent gone)=50 (number of students)
SO 43% is still there.
i hope this work for you

Find the distance from point L to point M, if the point L has coordinates (-10,-9)
and the point M has coordinates (-2,6).
Answer:
The distance from point L to point M is 17
Step-by-step explanation:
Distance Between two Points in the Plane
Given two points A(x1,y1) and B(x2,y2), the distance between them is calculated as follows:
[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
Point L has coordinates (-10,-9) and point M has coordinates (-2,6).
Calculate the distance between L and M:
[tex]d=\sqrt{(6+9)^2+(-2+10)^2}[/tex]
[tex]d=\sqrt{15^2+8^2}[/tex]
[tex]d=\sqrt{225+64}=\sqrt{289}[/tex]
[tex]\boxed{d=17}[/tex]
The distance from point L to point M is 17

[tex]36\div6+7[/tex]
[tex]36\div6=6[/tex]
[tex]6+7=13[/tex]
[tex]=13[/tex]
Second option:

[tex]4+8=12[/tex]
[tex]12\times4\div6+7[/tex]
[tex]12\times4=48[/tex]
[tex]48\div6+7[/tex]
[tex]48\div6=8[/tex]
[tex]8+7=15[/tex]
[tex]=15[/tex]
Which means your answer is the second option or "4 + (8 × 4) ÷ 6 + 7."

After a successful Friday night at the local BDubs, 92% of the daily allocated wings were sold to restaurant-goers. The kitchen staff was a bit upset because that meant there were only 96 wings left between them to take home at the end of night. How many wings did BDubs start off with that night?
Answer:
88
Step-by-step explanation:
92% = 0.92
0.92(96) = 88.32
88 is rounded to the nearest wing
A stock rises in value from $20 to $40. Then it decreases in value from $40 to $20. Is the percentage increase from $20 to $40 the same as the percentage decrease from $40 to $20? Explain.
Answer:
No
Step-by-step explanation:
To find how much something is a percent of another number, divide it by said other number
20/40 = 0.5
0.5 × 100 = 50%
The first one is a 50% increase
Then, 40/20 = 2
2 × 100 = 200%
It is a 200% decrease
So no, because 50% doesn't equal 200%
please help me find mo
Answer:
MO = 25

Krystal Ball's pulse rate is 30% higher than its normal rate of 70bpm. What is her pulse rate? After
lying down it decreased 20%. What is her heart rate now?
Starting bpm = 91
Resting bpm = 72.8
=========================================================
Explanation:
A 30% increase is represented by the multiplier 1.30 because
100% + 30% = 1.00 + 0.30 = 1.30
So Krystal's initial heart rate is 1.30*70 = 91 bpm.
If you wanted, you can think of it like this
30% of 70 = 0.30*70 = 21 is added onto the initial 70 bpm to get 70+21 = 91 bpm.
-----------
To decrease by 20%, we use the multiplier 0.80 since
100% - 20% = 1.00 - 0.20 = 0.80
Losing 20% of something means we keep the remaining 80%
So,
80% of 91 = 0.80*91 = 72.8 bpm.
-----------
Here's one way to find the final bpm in one single line
1.30*0.80*70 = 72.8
in which you could write it like this
(1 + 0.30)*(1 - 0.20)*(70) = 72.8
The second way may be a bit longer, but I find it's more descriptive to see where the percentage increases vs percentage decreases are.

When solving an ______, use inverse operations to undo the operations.
Answer:
equation
Step-by-step explanation:
Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents, logarithms, and trigonometry. Mathematically, inverse operations are opposite operations. Addition is the opposite of subtraction; division is the opposite of multiplication, and so on.
[RevyBreeze]
Answer:
equation
Step-by-step explanation:
To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation. Performing the same operation on both sides of an equation does not change the validity of the equation, or the value of the variable that satisfies it.
