Find m angle ABC I really need the answer to this

Mathematics
2 answers:
barxatty [35]2 years ago

Step-by-step explanation:

As it is a right angle ,

2x + 14 + x + 7 = 90⁰

3x + 21 = 90⁰

3x = 69

x = 23

ABC = 23 + 7 = 30⁰

To find <ABC, the first thing you would need to do is to find angle DBA and the value of x

As <DBE is a right angle, <DBE is on the same straight line as well,meaning that it would be 90° , a right angle as well.

It also mean that the total sum of the angles unknown would be 90°

To find x,we need to set up an equation:
(2x+14)+ (x+7) = 90
3x+21 = 90
3x = 69
x = 23

Thus,<ABC would be
(23)+7
=30°

Hope it helps!

A taxicab charges $3.00 per person
Delicious77 [7]

Answer:

I believe the answer would be 20 miles max for one passenger.

Step-by-step explanation:

This is because if you create an equation out of this, knowing that only one passenger will be riding, you will get:

$3.00+$1.25x=$28       ($3 added too $1.25 times the number of miles (x) which equals the total amount you have ($28)).

x being the number of miles (so we need to calculate for x)

$3 + $1.25x = $28

-subtract 3 on both sides-

$1.25x=$28-$3

$1.25x=$25

-divide by 1.25 on both sides-

x=$25/$1.25

x=20 miles

Not sure if all calculations are correct, but I hope this helps :)!

I rlly need help with this gr 11 math problem
prohojiy [21]

Answer:

a) \frac{d-5.50}{0.45}

b) The inverse function is a reflection of the original function across the line

y = x. For example, if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x. So you would use it to find the x-value at a y just like you use the original to find the y value at an x.

Step-by-step explanation:

To do an inverse of a function you first switch the independent variable (d) and the dependent variable (c).

d = 0.45c + 5.50

Then you solve for c

d - 5.50 = 0.45 c

c = (d-5.50)/0.45

inessss [21]

Answer:

4

Step-by-step explanation:

To find the common ratio, take the second term and divide by the first term

24/6 = 4

Check by taking the third term and dividing by the second term

96/24 = 4

The common ratio is 4
