Answer:
add all the rest of the angles, and then subtract the sum from 1080, and that's your ans mate
Answer:
147
Step-by-step explanation:
If you add up all the angles you have, you get 933. Since an octagon has 1080 degree angles the last angle must be added to 933 to make it equal to 1080. If you subtract 933 from 1080, you get the remaining angle 147.

lilli has $3.65 comprised of quarters and dimes floating on the bottom of her bag she has five more dimes than twice her quarters how many each type of coin does she have? lol pls help
Answer:
7 quaters and 19 dimes
Step-by-step explanation:
Let say x the numbers of quaters,
2*x+5 the numbers of dimes
In cents,: 25*x+10*(2x+5)=365
25x+20x+50=365
45x=365-50
45x=315
x=7
Number of quaters: 7
Number of dimes: 2*7+5=19
Proof:
7*25+10*19=365
Considerando um atleta de 1,83 m e o ângulo de inclinação de 20 graus formada pela ponta da vara com o chão é correto afirmar que o comprimento aproximado da vara mede?

Consider this sequence of transformations performed on shape I: a dilation by a scale factor of 2, followed by a reflection across the x-axis, and then a translation left 1 unit. Does the sequence prove that shapes I and IV are similar? Explain your answer.
Answer:
The sequence does map shape I onto shape IV. So, the sequence of transformations proves the two shapes are similar.
Step-by-step explanation:
To check whether the sequence proves that shape I is similar to shape IV, check whether the given sequence of transformations maps shape I onto shape IV.
1. Dilate shape I by a scale factor of 2.
2. Then, reflect the dilated shape across the x-axis.
3. Finally, translate the reflected shape 1 unit left.

Sixteen is equal to 7 increased by the product of 3 and a number.
Answer:
number is 3
Step-by-step explanation:
let the number be n then the product of 3 and the number is 3n , so
16 = 7 + 3n ( subtract 7 from both sides )
9 = 3n ( divide both sides by 3 )
3 = n
That is the number is 3

I have the answers already but I really don't understand so I'm primarily in this for the explanation and work please!
Thank you <3
Answer:
h(g(f(x))) = -8x² - 40x - 50Step-by-step explanation:
Given:
f(x) = 2x + 5 g(x) = x²h(x) = -2xTo find h(g(f(x))) first find g(f(x)), substitute x with f(x):
g(f(x)) = g(2x + 5)Since g(x) = x², the value of g(2x + 5) is:
g(f(x)) = (2x + 5)²Now, the next step:
h(g(f(x))) = h((2x + 5)²) = -2(2x + 5)² = -8x² - 40x - 50pls answer this i need help
Answer:
Step-by-step explanation:
a) Number = x
Multiply it by 3 = 3*x = 3x
Now add 4 to it: 3x + 4
Equation:
3x +4 = 22
b)
3x + 4 = 22
Subtract 4 from both sides
3x + 4 -4 = 22 - 4
3x = 18
Divide both sides by 3
3x/3 = 18/3
x = 6
Answer:
Below in bold.
Step-by-step explanation:
The equation is
3x + 4 = 22
3x = 22 - 4 = 18
x = 18/3
x = 6.
Emma had 10 Balls in a bag. The balls were numbers 1 through 10. She wanted to test the probability of drawing a ball that is a multiple of 3.
Also, write a prediction about if there is an unlikely, impossible, likely, even, or certain change of drawing a multiple of 3.
Answer:
30%UnlikelyStep-by-step explanation:
The balls - multiples of 3 are:
3, 6 and 9The probability of a multiple of 3 is:
3 out of 10 orP = 3/10 = 30%30% probability is in the range 0%-50% so this event is unlikely
Total multiples=3
[tex]\\ \sf\longmapsto P(3)=\dfrac{Multiples\:of\:3}{Total \:balls}[/tex]
[tex]\\ \sf\longmapsto P(3)=\dfrac{3}{10}[/tex]
[tex]\\ \sf\longmapsto P(3)=30\%[/tex]
It is <50%;So it is unlikely to happen.

if 1kg is 1.00g then 3kg is 2.500g
Answer:
I Kg = 1000 g
3 Kg = 3000 Kg
Step-by-step explanation:
Kg - Hg - Dag - g
1 Kg - 10 Hg - 100 Dag - 1000 g
So, 1 Kg = 1000 g
3 Kg = 3(1000)g = 3000 g

by using the formula, we can find :
T7 = [7⁴ - 6(7)³ +23(7)² - 18(7) +24] / 24 =
(2401 - 2058 + 1127 - 126 +24) / 24 =
1368/ 24 = 57
T8 = [8⁴-6(8)³+23(8)²-18(8)+24]/24 =
(4096-3072+1472-144+24)/24 =
2376/ 24 = 99

Dilation by a scale factor of 4 and a reflection over the x-axis
Answer:
(-12, -20).
Step-by-step explanation:
A dilation of factor 4 moves (-3, 5) to (-3*4, 5*4) = the point (-12, 20).
A reflection over the x-axis is (x, y) ------> ( x, -y).
So ( -12, 20) goes to (-12, -20).

In the function above n is a constant if f(9)=4 what is the value of f(-3)
Answer:
This equation is in y=mx + b form. Just plug in the point to get N, which is also B.
Whatever is in f(x) is your x. So x = 9; This means...
4 = 2/3(9) + n
Solving for n gets you -2.
Now we plug in -3 and also substitute N now that we solved for it.
f(-3) = 2/3(-3) - 2
f(-3) = -4
(A)
