Step-by-step explanation:
Line A is perpendicular to Line B.
If the slope of Line A is 3
what is the slope of Line B?
Answer:
- 1/3
Step-by-step explanation:
m = slope of a line
Perpindicular slope = - 1/m
= - 1/3
Let slope of that line be m
We know product of slopes of two perpendicular line=-1
3m=-1m=-1/3Is the quotient of 3 and 1/4 greater than or less than 3?
Answer:
Greater than
Step-by-step explanation:
The quotient of 3 and 1/4 would be 3/(1/4).
You could then multiply by the inverse of 1/4 to simplify the expression. This would give you [tex]3*\frac{4}{1}[/tex] or just 3 times 4. 3 * 4 = 12.
Since 12 is greater than 3, the quotient of 4 and 1/4 is greater than 3.

pls give the ans with explanation
Answer:
Step-by-step explanation:
100 cm = 1 m
25 cm = 25 ÷ 100 = 0.25 m
1000mm = 1m

What is the measure of the radius, c, rounded to the nearest hundredth? use an appropriate trigonometric ratio to solve. 5.88 cm 8.09 cm 12.36 cm 17.01 cm
The measure of the radius, c, rounded to the nearest hundredthis 12.36cm
Trigonometry identityThe given figure is a pentagon. The measure of one of the interior angle is 108 degrees.
The triangle in the pentagon is right angle.
Measured acute ange = 108/2 = 54 degrees
Using the trig identity
sin 54 = 10/c
c =10/sin54

- Meagan puts three flowering plants in a garden bed. Plant 1 and Plant 2 are 6 inches apart Plant 2 and Plant 3 are 10 inches apart Plant 1 and Plant 3 are 13 inches apart Did Meagan place the plants in a right triangle shape? Why or why notp?
Answer:
No
Step-by-step explanation:
They can't be in a straight line because 6+10 (the distance between plants 1 and 2 and plants 2 and 3) is more than 13 which is the distance from plant 1 to plant 3. This means plant 3 can't be in line with 1 and 2 which will give a triangular shape. If we check Pythagorean theorem we get 6^2 + 10^2 = 13^2 ( the longest side has to be the hypotenuse) . Since this isn't a true statement it can't be a right triangle.

Answer:
19.2 or 19.20
Step-by-step explanation:
Side 25=hypotenuse because it is across from the rightness of the triangleThis means that teh unknown side is a leg, as well as the side that says 16This makes our equation: a²+16²=25²Next we solve16²=256 and 25² is 625 so now our equation is a²+256=625We then subtract 256 from both sides which leaves us with x²=369To find the value of x, we take the square root of both sides. This leaves us with X=19.2What is the area of the shape?
Answer:
76
Step-by-step explanation:
to find the area of a square do base x height
7 x 8 = 56
to find the area of a triangle do base x height ÷ 2
3 x 8 = 24
24 ÷ 2 = 12
2 x 8 = 16
16 ÷ 2 = 8
8 + 12 + 56
= 76

Please answer explaining how a student such as this can get into college and the requirements they would need.
Students who will attend community college are not required to take SAT or ACT exams.
Given that,
Standardized test scores should no longer be used as a factor in college admissions because such tests put equity and integrity at stake. Standardized tests, such as the SAT and American College Testing (ACT) are not equitable enough to be used to determine an applicant's status of admission.Based on the information.
About 130 colleges and universities in California no longer require SAT or ACT tests for admission in fall 2022, according to the Los Angeles Times.

A circle that has (-2,4) and (4,2) as endpoints of a diameter.
Use the given information to write the standard equation of the circle.
I WILL MARK BRAINLIEST IF YOU GIVE ME THE CORRECT ANSWER!
Answer:
[tex]\implies (x-1)^2+(y-3)^2=10[/tex]
Step-by-step explanation:
End points of the diameter of the circle are:
[tex](-2,\:4) \implies x_1= -2, \: y_1= 4[/tex]
[tex](4,\:2) \implies x_2= 4, \: y_2= 2[/tex]
Equation of circle in diameter form is given as:
[tex](x-x_1)(x-x_2)+(y-y_1)(y-y_2)=0[/tex]
Plugging in the values of [tex]x_1, \: y_1,\:x_2, \: y_2[/tex] in the above equation, we find:
[tex][x-(-2)](x-4)+(y-4)(y-2)=0[/tex]
[tex]\implies (x+2)(x-4)+(y-4)(y-2)=0[/tex]
[tex]\implies x^2-2x-8+y^2-6y+8=0[/tex]
[tex]\implies x^2-2x+1-9+y^2-6y+9-1=0[/tex]
[tex]\implies (x^2-2x+1)-9+(y^2-6y+9)-1=0[/tex]
[tex]\implies (x-1)^2+(y-3)^2-10=0[/tex]
[tex]\implies (x-1)^2+(y-3)^2=10[/tex]
This is the required equation of circle in standard form.

The hypotenuse of a right triangle measures 4 cm and one of its legs measures 3 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Applying the Pythagorean theorem, the measure of the other leg, to the nearest tenth, is: 2.6 cm.
What is the Pythagorean Theorem?In a right triangle, where the lengths of its two legs are a and b, and the hypotenuse length is c, the Pythagorean theorem states that: c² = a² + b².
Given the following parameters of the right triangle:
c = 4 cma = 3 cmb = ? (other leg)Apply the Pythagorean theorem:
b = √(4² - 3²)
b = 2.6 cm (nearest tenth)
Thus, applying the Pythagorean theorem, the measure of the other leg, to the nearest tenth, is: 2.6 cm.

On January 1, Trisha put $100 into a savings account that earns interest. That same day, Mark put some money into another savings account that also earns interest. After 5 years, Trisha’s account balance is 145% of her original balance, and Mark’s is 160% of his original balance. Mark and Trisha withdraw all of their money and use it to spend $225 at the amusement park. If together they have $40 left from their withdrawals after the amusement park, how much did Mark put into his savings account?
Trisha thinks that if Mark also put $100 into his account, then they would had more than $100 left after the amusement park. Is she correct or not? Explain.
Answer:
Mark deposited $75Trisha is not correctStep-by-step explanation:
The total of their account balances is equal to the total spent plus the remaining amount. The given relations tell us ...
Trisha withdrew $100 × 145% = $145Mark withdrew d × 160% = 1.6d . . . for some initial deposit d$145 + 1.6d = $225 +40 . . . . . withdrawals = spent + change__
a.Solving this equation, we can find Mark's withdrawal and his initial deposit.
145 +1.6d = 265
1.6d = 120 . . . . . . . the amount Mark withdrew
d = 120/1.6 = 75 . . . . the amount Mark deposited
Mark put $75 into his savings account.
__
b.Had Mark put $100 into his savings account, the total of withdrawals would have been ...
Trisha + Mark = $100 × 145% +$100 ×160% = $145 +160 = $305
After spending $225 of this amount, they would have had a leftover amount of ...
$305 -225 = $80
Trisha is not correct in her thinking that there would be more than $100 left over.
