Answer:
2 inches of snow was left on the ground
Step-by-step explanation:
To calculate the amount of snow on the ground we can take it one step at a time. Since there was no snow on the ground we can start at a level of 0. Then it snowed until 6 inches of snow had fallen, so we can add that to our total.
0 + 6 = 6 inches
Next, it snowed for 2 more hours at a rate of 2 inches per hour, meaning we multiply this by 2 hours and add to the total amount of snow that was already on the ground.
(2*2) + 6 = 10 inches
Lastly, the sun came out and melted the snow on the ground for 2 hours at a rate of 4 inches per hour. Since it is melting the snow, this means that it is subtracting the snow from the total. So we would have to multiply the rate (4 inches per hour) by the number of hours and then subtract that from the amount of snow on the ground.
10 - (4*2) = 2 inches

Last year at a certain high school, there were 50 boys on the honor roll and 100 girls on the honor roll. This year, the number of boys on the honor roll decreased by 8% and the number of girls on the honor roll decreased by 15%. By what percentage did the total number of students on the honor roll decrease? Round your answer to the nearest tenth (if necessary). pls help
Answer:
46 for boys and 85 for girls
Step-by-step explanation:

8+-2w>4
I dont know this i gotta solve fore w.
Answer:
w < 2
Step-by-step explanation:
Subtract 8 from both sides.
-2w > -4
Divide both sides by two. WHEN YOU DIVIDE BY A NEGATIVE, the sign FLIPS!
w < 2

What is the slope of the line that passes through point (-8,3) and (-8,2)?
Answer:
[tex]\frac{-1}{0}[/tex] which is -1
Step-by-step explanation:
The slope formula is y2-y1 over x2-x1
So just plug it in. 2 - 3 = -1
-8 - -8 = 0
So the slope is -1 over 0
sam walks from home to his school which is 0.75 miles away in 12 minutes. how fast was he walking?
Answer:
3.75mph, or 0.0625 miles a minute
Step-by-step explanation:
12 times 5 is 60
.75 times 5 is 3.75
so he was walking mathematically 3.75 miles per hour
Answer:
3.75 mph
Step-by-step explanation:
12 minutes is 0.2 hours
0.75/0.2 = 3.75 mph

Answer:
Graphing y=1/2x-2 will look like this on the graph
Answer:
Step-by-step explanation:
the 1/2 is a gradient so you go up 1 for every 2 to the right
the -2 is the Y intercept so you start graphing the gradient from -2 on the Y axis

Step-by-step explanation:
29x - 3 + 15x + 7 = 18 because these two angles are supplementary
29x + 15x + 7 - 3 = 18044x = 176 divide both sides by 44x = 413y - 17 = 29x - 3 because these two angles are alternate
since we know the value of x
13y - 17 = 29 × 4 - 313y - 17 = 11313y = 113 + 1713y = 130 divide both sides by 13y = 1001) 8 + 6

The weight of a honeybee is 1.2\cdot10^{-1}\text{ g}1.2⋅10 −1 g1, point, 2, dot, 10, start superscript, minus, 1, end superscript, start text, space, g, end text. The weight of the pollen collected by the bee on one trip is 6.0 \cdot 10^{-2} \text{ g}6.0⋅10 −2 g6, point, 0, dot, 10, start superscript, minus, 2, end superscript, start text, space, g, end text. What is the combined weight of the bee and the pollen? Express your answer in scientific notation.
Answer:
0.18 g
Step-by-step explanation:
Weight of honeybee = [tex]1.2\times 10^{-1}\ \text{g}[/tex]
Weight of pollen = [tex]6\times 10^{-2}\ \text{g}[/tex]
The above values can be written in the following ways
[tex]1.2\times 10^{-1}\ \text{g}=0.12\ \text{g}[/tex]
[tex]6\times 10^{-2}\ \text{g}=0.06\ \text{g}[/tex]
Weight mass = [tex]0.12+0.06=0.18\ \text{g}[/tex]
The combined weight of the honeybee and the pollen is 0.18 g.
Answer:
1.8 x 10^-1
Step-by-step explanation:
it would be 0.18 withought scientific notation.

Given: Lines a and b are parallel and line c is a transversal. Prove: Angle2 is supplementary to Angle8 Horizontal and parallel lines a and b are cut by transversal c. On line a where it intersects line c, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 1, 2, 4, 3. On line b where it intersects line c, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 5, 6, 8, 7. What is the missing reason in the proof? Statement Reason 1. a || b, is a transv 1. given 2. ∠6 ≅ ∠2 2. ? 3. m∠6 = m∠2 3. def. of congruent 4. ∠6 is supp. to ∠8 4. def. of linear pair 5. ∠2 is supp. to ∠8 5. congruent supplements theorem corresponding angles theorem alternate interior angles theorem vertical angles theorem alternate exterior angles theorem
Answer:
The correct option is;
Corresponding angles theorem
Step-by-step explanation:
Type of lines of lines a and b = Horizontal and parallel lines
The transversal to a and b = Line c
The angles between a and c labelled clockwise from the upper left quarter segment = 1, 2, 4 and 3
The angles between b and c labelled clockwise from the upper left segment = 5, 6, 8 and 7
Therefore, we have;
Statement [tex]{}[/tex] Reason
1. a║b, c is a transversal [tex]{}[/tex] Given
2. ∠6 ≅ ∠2 [tex]{}[/tex] Corresponding angles theorem
3. m∠6 = m∠2 [tex]{}[/tex] Definition of congruent
4. ∠6 is supp. to ∠8 [tex]{}[/tex] Definition of linear pair
5. ∠2 is supp. to ∠8 [tex]{}[/tex] Congruent supplement theorem
Corresponding angles are the angles located in spatially similar or matching corners of two lines that have been crossed by the same transversal. When the two lines having a common transversal are parallel, the corresponding angles will be congruent.

Mark got 18 out of 25 questions correct on his science test. What percent of the questions did he get correct
Answer:
72%
Step-by-step explanation:
Turn the denominator to 100.
So: 18/25 times 4 equals 72/100
72/100= 72%
*You turn the denominator into 100 because all percents are out of 100.*

4(r + 20) = 1/5(20r + 400)
Answer:
r = r
Step-by-step explanation:
4(r + 20) = 1/5(20r + 400)
4r + 80 = 4r + 80
- 80 - 80
4r = 4r
4 4
r = r
Answer:
no solution
Step-by-step explanation:
4(r + 20) = 1/5(20r + 400)
4r + 80= 4r+ 80
-4r -4r
80= 80
