Johnny and Mark's combined age is 26 years old. Johnny is two years older than twice Mark's age. Write a system of equations and solve for each of their ages
m * 2 + 2 = j
Answer:
Mark is 8
Johnny is 18
Step-by-step explanation:
m * 2 = j - 2
26 - 2 = 24
24 / 3 = 8
8 * 2 + 2 = 18
A flagpole casts a shadow of 25.5 meters long. Tim stands at a distance of 15.4 meters from the base of the flagpole, such that the end of Tim's shadow meets the end of the flagpole's shadow. If Tim is 2.3 meters tall, determine and state the height of the flagpole to the nearest tenth of a meter.
Answer:
5.8 meters
Step-by-step explanation:
The formula to calculate this is given as:
Height/ Shadow
Shadow of the pole = 25.5 m
Height of the pole = x m
Tim's shadow = Height of the pole - Tim's distance
25.5 m - 15.4 m = 10.1 m
Tim's height = 2.3 m
Hence:
x/25.5 = 2.3/10.1
Cross Multiply
10.1x = 25.5 × 2.3
x = 25.5 × 2.3/10.1
x = 5.8069306931 m
Approximately = 5.8m
Hence, the height of the flagpole = 5.8m

Suppose y varies directly with x, and y = 13 when x = 4. What direct variation equation relates x and y? What is the value of y when x = –6?
Answer:
direct variation equation: y = 13/4x
y = -19.5 when x = -6
Step-by-step explanation:
y = kx where 'k' is the constant to proportionality
13 = 4k
k = 13/4
equation: y = 13/4x
plug in -6 for 'x' to find value of 'y'
y = 13/4(-6)
y = -19 1/2
Write an equation of the line that passes through the given point and has the given slope. (4, 2); slope 1/2
Answer:
y = 1/2x
Step-by-step explanation:
Substitute the given information into the equation y = mx + b
Your goal is to find what b is
Obviously, the point given --> (4, 2) is the x and y.
The m is the slope (1/2)

if $850 grows to $1125 at an interest rate of 12.6% compounded continuously, how long has the money been in the account?
Answer:
22 years approx.
Step-by-step explanation:
Step one
Given data
Principal P= $850
final amount A= $1125
rate r= 12.6%
Calculate time, solve for t
t = ln(A/P) / r
Step two:
Substitute
t= ln (1125/850)/0.0126
t=ln 1.32/0.0126
t= 0.277/0.0126
t=21.9
t= 22 years approx.

Kamilah noticed that three different-sized boxes of the same cookies were on sale at a grocery store. The 0.425 kg box was on sale for $3.59, the 0.74 kg box was on sale for $4.88, and the 0.95 kg box was on sale for $7.29. Which box of cookies was the best buy? Explain your reasoning. To get you started: 3.59 : 0.425 1kg/ 0.425kg= 2.35 0.425 x 2.35= 1kg $3.59 x 2.35= $8.44 3.59 : 0.425 -> $8.44 : 1kg
Answer:
The best buy is the 0.74 kg box
Step-by-step explanation:
Kamilah noticed that three different-sized boxes of the same cookies were on sale at a grocery store.
We find the unit price for 1 box
a) The 0.425 kg box was on sale for $3.59
= 1 kg = $3.25/0.425
= $7.6470588235
b) the 0.74 kg box was on sale for $4.88,
1 kg = $4.88/0.7$
= $6.5945945946
c) the 0.95 kg box was on sale for $7.29.
1 kg = $7.29/0.95
= $7.6736842105
Which box of cookies was the best buy?
The best buy is the 0.74kg box because 1kg of this box has a lesser price compared to the others.
