Answer:

22°

Step-by-step explanation:

Triangle KJL ≅ Triangle MJL (RHS)

[JL = JL(common), KL = LM(given), angle KLJ = angle MLJ(given)]

we come up to the conclusion that 4x + 6 = 3x + 10

x = 4

∴angle KJL = 4(4) + 6 = 22°

Slove for the variable<br> 2a-5=5a+23

Lyrx [107]

Answer:

$a = 9 \frac{1}{3}$

Step-by-step explanation:

$2a - 5 = 5a + 23 \\ 2a - 5a = 23 + 5 \\ - 3a = 28 \\ \frac{ - 3a}{ - 3} = \frac{28}{ - 3} \\ a = 9 \frac{1}{3}$

Write an equation for the nth term of the arithmetic sequence 56, 48, 40, 32, ....

Wittaler [7]

Answer:

an = 56-8(n-1)

Step-by-step explanation:

This is an arithmetic sequence

The common difference is 48 - 56 =-8

a1 = 56

an = a1+d(n-1)

an = 56-8(n-1)

Which two solid figures have the same volume? A. An oblique solid with a base of 4 cm2 and a height of 8 cm B. A cone with a bas

kkurt [141]

In general, Volume is equal to the area of the base multiplied by the height.

Let's check the volume of each.

V=area of base x height, all given, so,

$V=4*8=32$

Volume of cone is given by,

V= one-third area of base x height, all given, so,

$V=\frac{1}{3}*4*8= \frac{32}{3}$

Here, the slant height is given, not the altitude (height). The volume is not 32 nor $\frac{32}{3}$ .

Rectangular solid's volume is area of base times height, all given, so,

$V=4*8=32$

Hence, A and D have same volume.

ANSWER: Option A and Option D have the same volume (32)

Radio signals travel at a rate of 3 × 10^8 meters per second. How many seconds would it take for a radio signal to travel from a

stiv31 [10]

This question is an example of d = r * t

r = rate

r = 3*10^8 m/s

t = ??

d = 7.5 * 10^6 meters.

Sub and solve

d = r * t

7.5 * 10^6 = 3 * 10^8 * t Divide both sides by 3 * 10^8

7.5 * 10^6 / (3 * 10^8) = t

2.5 * 10^(6 - 8) = t

2.5 * 10^-2 seconds = t or

0.025 seconds = t
