Answer:

x = 1 1/25

x = 4 1/6

Step-by-step explanation:

(5 1/5) × 5 = 25x

(26/5) × (5/1) = 25x

26 = 25x

26/25 = x

1 1/25 = x

(8 1/3) × 2 = 4x

(25/3) × (2/1) = 4x

(50/3) = 4x

(50/3) ÷ (4/1) = x

(50/3) × (1/4) = x

50/12 = x

4 2/12 = x

4 1/6 = x

Answer:

3/7

Step-by-step explanation:

The fraction is ...

$24\text{ g to }56\text{ g}=\dfrac{24\text{ g}}{56\text{ g}}=\dfrac{3}{7}\cdot\dfrac{8\text{ g}}{8\text{ g}}=\boxed{\dfrac{3}{7}}$

Help pleaseeee ??????!!!!! I choosed the Death Valley one

disa [49]

1.) C(t) = -0.30(t - 12)^2 + 40
for t = 12: C(12) = -0.30(12 - 12)^2 + 40 = -0.30(0)^2 + 40 = 40°C
For t = 24: C(24) = -0.30(24 - 12)^2 + 40 = -0.30(24 - 12)^2 + 40 = -0.30(12)^2 + 40 = -0.30(144) + 40 = -43.2 + 40 = -3.2°C

4.) F(t) = 9/5 C(t) + 32
for C(t) = 40°C: 9/5 (40) + 32 = 72 + 32 = 104°F
for C(t) = -3.2°C: 9/5(-3.2) + 32 = -5.76 + 32 = 26.24°F

5.) F(t) = 9/5 C(t) + 32 = 9/5 (-0.30(t - 12)^2 + 40) + 32 = -0.54(t - 12)^2 + 72 + 32 = -0.54(t - 12)^2 + 104

Question 5

sergey [27]

Explanation : If 66 is a factor of this unknown value, then 22 must be as well considering that 22 is a factor off 66. Let's say that this large value is 330. It is a multiple of 66, as 66 $*$ 5 = 330. At the same time 22 $*$ 15 = 330, so 330 is a multiple of 22 as well - or vice versa, 12 is a factor of 330.

We can also tell that 15, 22 fit into 330 through another approach. 22 $*$ 3 = 66, and 66 $*$ 5 = 330, so 5 $*$ 3 = 15 - the same value. This proves that 22 will always be a factor of a value that is the factor of 66.

Country A has a growth rate of 3.4% per year. The population is currently 4,118,000, and the land area of Country A is 29,000

Eduardwww [97]

Answer:

time period is 260.57 years

Step-by-step explanation:

given data

growth rate = 3.4 % = 0.034

population = 4118000

area P = 29000000000 square yard

to find out

time period that one person for every square yard of land need

solution

we will apply here population growth formula that is

total population P = initial population × $e^{rt}$ ..............1

here r is rate of growth and t is time period and

we consider here initial population is current population

so put value in equation 1 to get t

29000000000 = 4118000 × $e^{0.034t}$

take ln both side

ln 7042.25 = ln $e^{0.034t}$

8.8596 = 0.034 t

t = 260.57

so time period is 260.57 years
