Ken made $14,500 in five months at his new job. How much can he make in two years if his pay remains constant?
Answer:
$69,600
Step-by-step explanation:
Figure out how much Ken makes a month by dividing 14500/5.
This gives you $2900.
If Ken makes $2900 a month and there are 24 months in two years, multiply his monthly earnings by 24 months.
$2900 * 24 = $69,600

Which best describes how to find an equation of the line shown?
A. The slope m is rise over run, so y over x =m. Solve for Y to get y=mx.
B. The slope m is run over rise, so x over y=m. Solve for x=ym.
C. The slope m is run over rise, so x over y=m. Solve for y to get y= x over m.
D. The slope m is rise over run, so x over y=m. Solve for x to get x=ym.
Answer:
AStep-by-step explanation:
m (slope) = rise = y = y₁ - y₁
run x x₁ - x₁
to get y = mx
therefore, the answer to the question is :
A. The slope m is rise over run, so y over x =m.
Solve for y to get y=mx.

first parentheses (PEMDAS)
-2×8d=-16d
-2×10f=-20f
-10×-7f=70f

Answer:119 4/7
Step-by-step explanation:
2/14+6/14+2/14+4/14+1/14+3/14+4/14= 22/14
10+35+10+12+24+15+12=118
118 22/14
119 8/14
119 4/7
Answer:
119 and 4/7
Step-by-step explanation:
10 + 12 + 15 + 24 + 12 + 10 + 35 = 118.
3/14 + 1/14 = 2/7
1/7 + 2/7 + 2/7 + 2/7 = 1
1/7 + 3/7 = 4/7
118 + 1 + 4/7 = 119 and 4/7
What is the width of a rectangle that has an area of 96 square inches and a length of 12 inches?
Answer:
width = 8
Step-by-step explanation:
to find the width of a rectangle you need to to the equation w= A ÷ l. when you put in the numbers you gets w = 96 ÷ 12.
96 ÷ 12 = 8 so w = 8
Answer:
The width is 8inches

On a 1 mile track, Runner A has made 18 laps in the time it took Runner B to make 8 laps. If Runner A is running 5 mph faster than Runner B, how fast is each of them running?
Answer:
Runner A is running at 9 mph while runner B is running at 4 mph
Step-by-step explanation:
From online values, 4 laps make 1 mile.
We are told Runner A has made 18 laps in the time it took Runner B to make 8 laps.
This means that runner A has run in mile; 18/4 = 4.5 miles
While runner B has run in miles; 8/4 = 2 miles
Runner A is running 5 mph faster than Runner B, thus speed of runner A is;
V_b + 5 while speed of runner B is V_b.
We know that; time = distance/speed
Thus;
t_a = 4.5/(V_b + 5)
t_b = 2/V_b
Since the times are equal from the question, then;
4.5/(V_b + 5) = 2/V_b
Cross multiply to get;
4.5V_b = 2(V_b + 5)
4.5V_b = 2V_b + 10
4.5V_b - 2V_b = 10
2.5V_b = 10
V_b = 10/2.5
V_b = 4 mph
Since V_a = V_b + 5
Thus, V_a = 4 + 5 = 9 mph
Runner A is running at 9 mph while runner B is running at 4 mph

Answer:
1.125 or 9/8 batches of muffins
Step-by-step explanation:
m = 0.5s where m = the amount of muffins and s = the lb of strawberries
m = 0.5(2.25)
m = 1.125 or 9/8 batches of muffins
Answer:
4.5 batchesStep-by-step explanation:
1 batch = 1/2 poundsx batches = 9/4 poundsCross-multiplication:
x*1/2 = 1*9/4x = 9/4*2x = 9/2x = 4.5 batchesn/-5=7 it is due today

(02.07)A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
A triangle ABC is shown. The base of the triangle extends into a straight line. The angle formed between this straight line and the edge of the triangle is marked as p. The angle adjacent to p is marked as o, and the other two angles inside the triangle are marked as m and n.
Step 1: m∠m + m∠n + m∠o = 180 degrees (sum of angles of a triangle)
Step 2: m∠p − m∠o = 90 degrees (alternate interior angles)
Step 3: Therefore, m∠m + m∠n + m∠o = m∠o + m∠p
Step 4: So, m∠m + m∠n = m∠p
In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (corresponding angles)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
Step 2; it should be m∠o + m∠p = 180 degrees (supplementary angles)
Answer:
I'm pretty sure it's the last option. Step 2; it should be m<o+m<p=180 degrees (supplementary angles)
Step-by-step explanation:
I think it's the last one since m<o and m<p are supplementary.
