Answer:
98^91
Step-by-step explanation:
Since the base of all the numbers is 98,
the LCM is simply the one with the greatest exponent
example
98^53 * 98^38 = 98^91

Which of the following can be the sides of a right angled triangle?
(i) 1.5 cm, 2 cm, 3 cm (ii) 6 cm, 1.1 cm, 6.1 cm
Answer:
(ii) 6 cm, 1.1 cm, 6.1 cm
Step-by-step explanation:
Knowing that all right triangles obey the Pythagorean Theorem, we can test both sets of numbers. The longest of the 3, the hypotenuse, is substituted to the c value of the equation a^2 + b^2 = c^2. If the equation is still true after substituting and simplifying both sides, that combination of triangle lengths is the correct answer. In this case, 6^2 + 1.1^2 and 6.1^2 are both equal to 37.21, so the second set is correct.

A car travels 20miles be in 1/2 hour at constant speed is traveling at the same speed as a car that travels 30 miles in 3/4 hour at a constant speed.explain or show why
Answer:
It is true that both cars are traveling at the same speed.
Step-by-step explanation:
Given that car A travels 20 miles over half an hour, we know that this car is traveling at a speed of 40 miles per hour.
Car B travels 30 miles in 3/4 of an hour, let us set up a proportion to solve whether or not Car B is traveling at the same rate as Car A
30 miles / (3/4 hour) = x miles / 1 hour Cross multiply
30 = (3/4) x Divide both sides by (3/4)
40 = x
Therefore, both Car A and Car B are traveling at the same rate.
Step-by-step explanation:
Find the equation of the line that passes through (-3,1) and is parallel to y = 1 − 2 x . Leave your answer in the form y = m x + c
Answer:
y = - 3x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + y - 1 = 0 ( subtract 3x - 1 from both sides )
y = - 3x + 1 ← in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, thus
y = - 3x + c ← is the partial equation
To find c substitute (1, 4) into the partial equation
4 = - 3 + c ⇒ c = 4 + 3 = 7
y = - 3x + 7 ← equation of line in form y = mx + c

What is the measure of angle L
Answer:
∠L=23°
Step-by-step explanation:
(6x-5)+(x+9)=(9x-24) (ext angle of triangle)
6x-5+x+9=9x-24
7x+4=9x-24
7x-9x=-24-4
-2x=-28
2x=28
x=28÷2
=14
Hence, ∠L = (x+9)°
= (14+9)°
= 23°

a/6-1/2=1/3 thats 7 grade math
Answer: a = 5
Step-by-step explanation:
a/6-1/2=1/3
a/6 = 1/3 + 1/2
a/6 = 2/6 + 3/6
a/6 = 5/6
a = 5
Check:
5/6-1/2 = 1/3 ?
5/6 - 3/6 = 1/3?
2/6 = 1/3 ?
1/3 = 1/3 YES
Answer:
a = 5
Step-by-step explanation:
a/6 - 1/2 = 1/3
=> a/6 = 5/6
=> a = 5
