What is the length of BC?
9 units
11 units
15 units
16 units
Answer:
x = 15
Step-by-step explanation:
I used the pythagorean theorem on BAC triangle
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below ;)
The length of BC is 15 units.
In the right triangle ABC.
we have AC = 8 units and AB = 17 units.
We need to find the length of BC using the Pythagorean theorem.
What is the Pythagorean theorem?It states that in a right-angled triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides.
In the given right-angle triangle ABC.
We have,
AB = hypotenuse and the other two sides are AC and BC.
Applying the Pythagorean theorem.
We get,
[tex]AB^{2} = AC^2 +BC^2[/tex]
Now substitute AC = 8 and AB = 17.
[tex]17^2=8^2+BC^2\\289=64+BC^2\\BC^2=289-64\\BC^2=225\\BC=\sqrt{225}\\ BC=15 ~units.[/tex]
Thus, we have the length of BC as 15 units.

Calculate the following using the Density Formula: What is the volume of the Ms. Gonsalez's phone that he dropped in his sink, if the mass of the phone is 12.4 g and the density is 6.2 g/mL? *
Answer:
2 mL³
Step-by-step explanation:
Use the density formula, D = m/v, where m is the mass and v is volume.
Plug in the mass and density, then solve for the volume:
D = m/v
6.2 = 12.4/v
6.2v = 12.4
v = 2
So, the volume is 2 mL³

Franco made a dozen muffins for his party. Upon taking them out of the oven, he noticed that 2 of the muffins were badly burned. Franco served 710 of the remaining muffins. Which equation shows the fraction of the non-burned muffins that remains? A. 1212−712=512 B. 1010−710=310 C. 1212−512=712 D. 1010−310=710
Answer:
10/10 - 7/10 = 3/10
Step-by-step explanation:
Muffins made = 12
Burnt muffins = 2
Good muffins = 12 - 2 = 10
Franco served 7/10 of the remaining muffins
Muffins served = 7/10 × 10
= 7
Muffins unserved = 10 - 7 = 3
Fraction of the non burned muffins remaining = non burned muffins - served muffins
= 10/10 - 7/10
= 3/10

7. Cassidy's family is driving home
from vacation at an average speed
of 55 mph. After 2 hours they
are 110 miles from home. What
is an equation in point-slope that
represents their distance from
home, y, after x hours?
Answer:
The equation in a point-slope form that represents their distance from
home, y miles, after x hours, is y - 110 = 55(x - 2)
Step-by-step explanation:
The point-slope form of the linear equation is
[tex]y-y_{1}=m(x-x_{1})[/tex] , where
m is the slope of the line (average)
[tex](x_{1},y_{1})[/tex] is a point on the line
→ The family is driving home from vacation at an average speed
of 55 miles per hour
∴ m = 55
→ After 2 hours they are 110 miles from home
∵ x is the number of hours
∵ y is the distance in miles after x hours
∴ [tex]x_{1}[/tex] = 2
∴ [tex]y_{1}[/tex] = 110
→ Substitute these values in the form of the equation above
∴ y - 110 = 55(x - 2)
The equation in a point-slope form that represents their distance from
home, y miles, after x hours is y - 110 = 55(x - 2)

factor the trinomial x²-11x+30?
Answer:
(x-5)(x-6)
Step-by-step explanation:
when we look at something like this we have a, b, and c
a=1 (in front of x)
b=-11
c=30
our goal is trying to find factors of c that will give us b so in this case factors of 30 that will give us -11
so when you list all the factors of 30 you find that 6 and 5 both equal 30 when multiplied and add up to 11
but... we need -11 so if we change the signs both to negative that will give us a -11 when added and also a positive 30 when multiplied (-6)(-5)
so we then write it as (x-6)(x-5)
and if you FOIL that out you will end up getting the original equation :)
hope this helps!
What value of c makes the equation true?
let's solve your equation step-by - step
-3-3/4(c-4)=5/4
Step 1: simplify both sides of the equation.
-3-3/4(c-4)=5/4
-3+-3/4 c+3=5/4 (distribute)
(-3/4 c)+(-3+3)=5/4 (combine like terms)
-3/4c=5/4
-3/4 c =5/4
Step 2: Multiply both sides by 4/(-3)
(4/-3)*(-3/4 c)=(4/-3)*(5/4)
Answer:c=-5/3
Answer:
[tex]-\frac{5}{3}[/tex]

please help. find the measure of all missing angles.
Answer:
M1= 62 M2= 45 M3= 24
Step-by-step explanation:
For angle 1:
180-118 = 62
Angle 2:
180- (73+62)
Angle 3:
part 1
180-73= 107
part 2
180-(107+49)= 24
Answer:
Step-by-step explanation:
You have to solve for 1 before you do anything.
<1 + 118 = 180 The two left angles are supplementary
<1 +118-118=180-118
<1 = 62
Now you can go after angle 2
<1 + 73 + <2 = 180 All triangles have 180 degrees
62 + 73 + <2 = 180 Combine the left
135 + <2 = 180 Subtract 135 from both sides.
135-135+<2 = 180-135 Combine
<2 = 45
Angle 3 is a little trickier because the angle you need to find <3 is not labeled.
73 + x = 180
x = 180 - 73
x = 107
NOw you can find <3
107 + 49 + <3 = 180
156 + <3 = 180
<3 = 180 - 156
<3 = 24
I have left out the reasons for <3. Maybe you can supply them.

Answer:
2
Step-by-step explanation:
3−2(x+1)=2x−7
3+(−2)(x)+(−2)(1)=2x+−7(Distribute)
3+−2x+−2=2x+−7
(−2x)+(3+−2)=2x−7(Combine Like Terms)
−2x+1=2x−7
−2x+1=2x−7
Step 2: Subtract 2x from both sides.
−2x+1−2x=2x−7−2x
−4x+1=−7
Step 3: Subtract 1 from both sides.
−4x+1−1=−7−1
−4x=−8
Step 4: Divide both sides by -4.
−4x−4=−8−4
