Refer to the given figure. If QR=3x+4, KL=15, JL=2x+10, find the measure of JL. A. 2 B. 6 C. 18 D. 22
Answer:
Option C
Step-by-step explanation:
From the given figure, it is clear that the two triangles are similar to each other with QR = KL
As we know
QR = 3x+4 and KL = 15, we can derive the value of X
3X+4 = 15
X = 11/3
Jl = 2X + 10 = 2*11/3 +10 = 22 +30/3 = 52/3 = 18
hence, option C is correct
Maria sets a goal of jogging 17.4 miles this week.She plans on running 2.75 miles each day for 7 dadys.If she follows her plan,witch is true?
Step-by-step explanation:
Given
Maria goal's is to Jog 17.4 miles
She runs 2.75 miles each day for 7 days
Total distance covered by her in 7 days
[tex]\Rightarrow 2.75\times 7=19.25\ \text{miles}[/tex]
So, she covers more than what she had planned.
Therefore, she is successful in her plan.

Are the ratios 18:9 and 2:1 equivalent?
Answer:
Yes
Step-by-step explanation:
[tex]\frac{18}{9} =\frac{2}{1}[/tex]
The two ratios are,
→ 18 : 9 and 2 : 1
We have to find,
→ whether the ratios are equivalent?
Now simplify the first ratio,
→ 18(÷9) : 9(÷9) = 2 : 1
→ 2 : 1 = 2 : 1
Yeah, the two ratios are equivalent.

Oz= -8
O x = 12
O infinitely many solutions
O no solution
Answer:

Write the equation of a line that passes through the point (-5,-4) and has
a slope of 1/5.
O y = 0.2x + 3
O y = 0.2x - 3

Answer:
B) y=1/5x-3 where 1/5=0.2.
Step-by-step explanation:
y-y1=m(x-x1)
y-(-4)=1/5(x-(-5))
y+4=1/5(x+5)
y=1/5x+5/5-4
y=1/5x+1-4
y=1/5x-3

Henry visits the library once every 6 days while James visits it once every 4 days. Both meet each other at the library for the second time on Thursday. On which day of the week did they meet each other for the first time?
Answer:
They met on Sunday for the first time.
Step-by-step explanation:
This can be found out by taking the LCM
The factors of 6 = 1*2*3
The factors of 4= 1*2*2
LCM = 2*2*3= 12
They both will meet on the 12 day for the second time.
If Thursday is the 12th day then counting backwards , they met on Sunday for the first time.

This graph represents the function f(x)=sin(2x)
Answer:
a
Step-by-step explanation:
a is the correct statement because there is a relative minimum at 3pi/4 and y values are negative on the interval [pi/2,pi]
The function is negative on the interval (π/2, π) option (A) is correct.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have a graph of a sin function shown in the picture.
As we know the sin function can be defined as the function which is sinusoidal in nature, and it has a domain of all real numbers and lies between the [a, a] where is the amplitude of the function.
The sin function is:
f(x) = sin(2x)
From the graph, the region between (π/2, π) the function values is negative because the function exists in the IV quadrant.
Thus, the function is negative on the interval (π/2, π) option (A) is correct.

what is the value of v in the equation -25=-(4v+7)+10
Answer:
-25 = -(4v+7)+10
-25 = -4v-7+10
-25 = -4v+3
4v = 3+25
4v = 28
v = 28 ÷ 4
v = 7
Answer:
Therefore the value of v in the equation is 7

ASAP someone please use the Pythagorean Theorem to solve for the missing side of these two right triangles.
Answer:
9) x = 5
10) x = 4
Step-by-step explanation:
a^2 + b^2 = c^2
9) 6^2 + x^2 = 8^2
- 36 + x^2 = 64
- 36 - 36
_______________
x^2 = 28
Square root them
Squareroot x^2 is x
Square root 28 is 5.29 round is 5
so x = 5
*Correct me if im wrong*
10) 3^2 + x^2 = 5^2
9 + x^2 = 25
- 9 - 9
____________________
x^2= 16
Square root them
square root of x ^2 is x and square root of 16 is 4
so x = 4
A 10-foot ladder leans against a wall so that it is 6 feet high at the top. The ladder is moved so that the base of the ladder travels toward the wall twice the distance that the top of the ladder moves up. How much higher is the top of the ladder now? (Hint: Let 8−2x be the distance from the base of the ladder to the wall.)
Answer:
Step-by-step explanation:
The Pythagorean Theorem holds for both positions.
The first configuration is an 6-8-10 right triangle.
The second configuration using the Pythagorean Theorem:
10^2 = (8-2x)^2 + (6 + x)^2
100 = 64 - 32x + 4x^2 + 36 + 12x + x^2
100 = 100 - 20x + 5x^2
5x^2 - 20x = 0
5x(x - 4) = 0
x = 4 feet (we throw out the x = 0 solution as extraneous)
Answer:
Step-by-step explanation:
The Pythagorean Theorem holds for both positions.
The first configuration is an 6-8-10 right triangle.
The second configuration using the Pythagorean Theorem:
10^2 = (8-2x)^2 + (6 + x)^2
100 = 64 - 32x + 4x^2 + 36 + 12x + x^2
100 = 100 - 20x + 5x^2
5x^2 - 20x = 0
5x(x - 4) = 0
x = 4 feet (we throw out the x = 0 solution as extraneous)

The probability that a person cannot read is 0.85 what is the probability that 2 people selected at random will be unable to read
Answer: 0.7225
Step-by-step explanation:
Since the probability that a person cannot read is 0.85. The probability that 2 people selected at random will be unable to read will be gotten by multiplying the value of the probability given twice. This will be
= P(not read) × P(not read)
= 0.85 × 0.85
= 0.7225
Therefore, the probability that 2 people selected at random will be unable to read is 0.7225

A turtle and a snail are 360 meters (who counts this again?) apart, and they start to move towards each other at 3 pm. If the turtle is 11 times as fast as the snail, and they met at 3:40 pm, find the speed of each.
Thank you!! :)
Answer:
Turtle = 11 m / min
Snail = 1 m / min
Total approach speed = 12 m/min
360 m / (12 m/min) = 30 min
Separation is 30 min at assumed speed of 1 m/min
But we know the separation is 40 min
So turtle moves at 3/4 * 11 m / min = 33 m/ 4 min
Snail moves at 3/4 * 1 m /min = 3/4 m / mi
Total approach speed = (33 + 3) / 4 = 9 m / min
So in 40 min
9 m / min * 40 min = 360 m
(Leaving out those units, they approach at 12 * unit of speed)
So the unit of speed has to be 360 m / 40 min = 9 m / min
