Shannon walks 2,500 metres in 1 hour 40 minutes.
How far does she walk in one minute?
Answer:
25m
Step-by-step explanation:
Shannon's rate is 2,500m/100min. Simplifying, we see that this is equal to 25m/1min.
So, she walks 25 m in one minute.

Answer:
x is 13
y is 39
Step-by-step explanation:
Answer:
y= 39 x= 10
Step-by-step explanation:
congruent isosceles triangles
longer sides measure the same 13 and 13 39 and 39 ( y =39)
39/30 = 13/x
cross multiplication:
39x = 13x30
39x = 390
x=10

A bag contains 37 coins consisting of only dimes and quarters.The total amount of money in the bag is $6.85. How many dimes are in the bag ??
Answer:
16 dimes
Step-by-step explanation:
D=number of dimes
Q=number of quarters
D+Q=37
.25 xQ + .10 x D=6.85
sub Q from first equation
.25(37-D) + .10 x D=6.85
D(.10-.25) + .25 x 37 =6.85
-.15D + 9.25=6.85
D= (6.85-9.25)/(-.15)
D=16

Which ratio is not equivalent to the other three? A 2 3 B 12 15 C 18 27 D 6 9
Answer: B= 12 15
Step-by-step explanation:
The given ratios are
A) 2 3= 2: 3 already in its simplest form
B) 12 15 =12:15 Changing to its simplest form, we divide both by 3 giving us 4:5
C) 18 27 =18: 27 Changing to its simplest form, we divide both numbers by 9 giving us =2:3
D)6 9=6:9 Changing to its simplest form, we divide both by 3 giving us
2:3
Therefore the ratio not equivalent to other three is 12:15

A cube that has a length of 1cm on each side has a volume of 1 cmHow many cubic
centimeters are in 1 cubic meter? (Hint: The answer is not 100.)
Answer:
1 cubic centimetre =1 × 10^-6 cubic metre
Step-by-step explanation:
A cube that has a length of 1cm on each side has a volume of 1 cm. How many cubic centimeters are in 1 cubic meter? (Hint: The answer is not 100.)
From the above question,
Side length of the cube = 1cm
Volume of the cube = (side length)³
= (1cm)³
= 1 cm³
How many cubic centimeters are in 1 cubic meter?
Note that:
100 cm = 1 m
1 cm³ = x m³
1 cm³ = (1/100 × 100 × 100)m³
1 cm³ = 1 × 10^-6 m³
Therefore,
1 cubic centimetre =1 × 10^-6 cubic metre

3(r+2)+5(2-r) =-32 can someone tell em the answer to that please
Answer:
r = 24
Step-by-step explanation:
3(r+2)+5(2−r)=−32
Step 1: Simplify both sides of the equation.
3(r+2)+5(2−r)=−32
(3)(r)+(3)(2)+(5)(2)+(5)(−r)=−32(Distribute)
3r+6+10+−5r=−32
(3r+−5r)+(6+10)=−32(Combine Like Terms)
−2r+16=−32
−2r+16=−32
Step 2: Subtract 16 from both sides.
−2r+16−16=−32−16
−2r=−48
Step 3: Divide both sides by -2.
−2r/-2 = -48/-2
r = 24
Answer: r = 24
3(r+2)+5(2-r) =-32
this equals (if we do the multiplication)
3r+6+10-5r=-32
this equals (if we simplify)
-2r+16=-32
this equals (because we are subtracting from 1 side, we must subtract from the other)
-2r=-48
r=24

PLEASE HELP, find the orthocenter of this triangle
Answer:
The orthocenter of a triangle is the point at which the three altitudes of a triangle intersect. This involves creating 3 lines, one from each vertex (K, L, and M) perpendicular to the line segment opposite it, so K⊥LM, L⊥KM, and M⊥KL.
Because these three lines intersect at one point, you only need to do this procedure for two of the three altitudes. Because K and M are on the same Y coordinate (-4), lets do this for LM and KL
First, we need to find the slope of the perpendicular to each line segment, so we need the slope of LM and KL.
The slope is the change in Y over the change in X
Slope LM = 6 -(-4) / 2-7 = 10/-5 = -2
Slope KL = -4-(6) / 4-2 = -10/2 = -5
The slope of a perpendicular line is the negative reciprocal of the slope of the given line, so for
the slope of K⊥LM has to be 1/2 and
the slope of M⊥KL has to be 1/5
Second, the vertex has to be on a line with that slope. So using the point-slope formula
(y-y1) = m(x-x1) , where x1,y1 is a point on the line for each line gives us
K⊥LM: y-(-4) = 1/2(x-4)
M⊥KL: y-(-4) = 1/5(x-7)
Third, find the point on both lines, are where the two equations are equal
So, 1/2(x)-2 = 1/5(x) - 7/5;
5x - 20 = 2x - 14
3x = 6 --> x=2
y+4=-1 --> y=-5
