There is a larger variety of lengths in the 9th grade textbook

Answer:

Angle of elevation = 48.60° (Approx.)

Step-by-step explanation:

Given:

Vertical Height = 150 feet

Horizontal angular length of drone = 200 feet

Find:

Angle of elevation

Computation:

Using trigonometry function

⇒ Sinθ = Perpendicular / Hypotenuse

⇒ Sinθ = Vertical Height / Horizontal angular length of drone

⇒ Sinθ = 150 / 200

⇒ Sinθ = 0.75

⇒ Sin⁻¹(0.75) = θ

Angle of elevation = 48.60° (Approx.)

Answer: $4,813.24

Step-by-step explanation:

This requires the use of a future value formula because we are to find the value of an amount in future after compounding it over a certain period.

Future Value = Amount * (1 + rate) ^ number of years

= 2,000 * ( 1 + 5%)¹⁸

= $4,813.24

In 18 years, the $2,000 would have increased to $4,813.24.

Answer:

Step-by-step explanation:

18 - 7m > 0 ⇒ 7m < 18 ⇒ m < 18/7

Answer:

[tex] \displaystyle m_{1} = 2 \quad \text{and} \quad \displaystyle m _{2} = - 9[/tex]

Step-by-step explanation:

we are given a logarithm equation

[tex] \displaystyle \log_{4}( {m}^{2} ) = \log_{4}(18 - 7m) [/tex]

notice that, we have [tex]\log_4[/tex] both sides therefore we can get rid of it

[tex] \displaystyle {m}^{2} = 18 - 7m[/tex]

in order to solve it we should make it standard form we know that

[tex] \displaystyle a {x}^{2} + bx + c = 0[/tex]

so right hand side expression to left hand side and change its sign:

[tex] \displaystyle {m}^{2} + 7m- 18=0[/tex]

now we can solve it by using factoring method

to do so rewrite the middle term as sum or subtraction of two different terms

in that case -2m+9m is good to use

[tex] \displaystyle {m}^{2} - 2m + 9m - 18 = 0[/tex]

factor out m:

[tex] \displaystyle m({m}^{} - 2 )+ 9m - 18 = 0[/tex]

factor out 9:

[tex] \displaystyle m({m}^{} - 2 )+ 9(m - 2)= 0[/tex]

group:

[tex] \displaystyle (m - 2)(m + 9) = 0[/tex]

hence,

[tex] \displaystyle m_{1} = 2 \quad \text{and} \quad \displaystyle m _{2} = - 9[/tex]

remember that,

when we deal with logarithm equation we should always check the roots

let's check the root 1:

[tex] \displaystyle \log_{4}( {2}^{2} ) \stackrel{?}{=} \log_{4}(18 - 7.2) [/tex]

simplify square:

[tex] \displaystyle \log_{4}( 4) \stackrel{?}{=} \log_{4}(18 - 7.2) [/tex]

simplify multiplication:

[tex] \displaystyle \log_{4}( 4) \stackrel{?}{=} \log_{4}(18 - 14) [/tex]

simplify substraction:

[tex] \displaystyle \log_{4}( 4) \stackrel{?}{=} \log_{4}(4) [/tex]

simplify logarithm:

[tex] \displaystyle 1 \stackrel{ \checkmark}{=} 1[/tex]

let's check root 2:

[tex] \displaystyle \rm \log_{4}( { - 9}^{2} ) \stackrel{?}{=} \log_{4}(18 - 7.( - 9)) [/tex]

simplify square:

[tex] \displaystyle \rm \log_{4}( 81 ) \stackrel{?}{=} \log_{4}(18 + 63) [/tex]

simplify addition:

[tex] \displaystyle \rm \log_{4}( 81 ) \stackrel{ \checkmark}{=} \log_{4}(81) [/tex]

therefore,

[tex] \displaystyle m_{1} = 2 \quad \text{and} \quad \displaystyle m _{2} = - 9[/tex]

Step-by-step explanation:

Answer:

Miguel walks 4.25 blocks more than Jila.                      

Step-by-step explanation:

Line plot shown in the question represents the distance traveled by the students from their houses to their school.

From the line plot,

Distance between 1 and 2 = [tex]\frac{1}{4}[/tex] = 0.25 blocks

Shortest distance traveled by Miguel = 0.25 blocks

Longest distance traveled by Jila = 4.5 blocks

Difference between the distances covered by Miguel and Jila = 4.5 - 0.25

= 4.25 blocks

Therefore, Miguel walks 4.25 blocks more than Jila.

Answer: It will take 1.875 hours

Step-by-step explanation:

Given that time t required to do a job varies inversely as the number of people working.

we have it expressed as

t∝1/N

where t is time  required to do a job

N is the number of people working.

Introducing our constant of proportionality, we have tht

t=k1/N

t=k/N

Now since it takes 5 hr for 3 cooks to prepare the food , K becomes

t=k/N

5=K/3

K=5X3=15

Given that there are 8 cooks, time required to prepare dinner will be

t=k/N

t=15/8

t=1.875 hours

Step-by-step explanation:

4374 x 3 = 13122

Solution :

It is given that Little Snail is going to visit one of his friend at the pond which is 3 miles away.

When the snail crawls 1/2 of a mile per day, it will take him, [tex]$1 \times \frac{2}{1} \times 3$[/tex]

   =  6 days to get to the next pond.

When the snail crawls 1/3 of a mile per day, it will take him, [tex]$1 \times \frac{3}{1} \times 3$[/tex]

   =  9 days to get to the next pond.

When the snail crawls 1/4 of a mile per day, it will take him, [tex]$1 \times \frac{4}{1} \times 3$[/tex]

   = 12 days to get to the next pond.

When the snail crawls 3/4 of a mile per day, it will take him, [tex]$1 \times \frac{4}{3} \times 3$[/tex]

   =  4 days to get to the next pond.

When the snail crawls 2/3 of a mile per day, it will take him, [tex]$1 \times \frac{3}{2} \times 3$[/tex]

   =  4.5 days to get to the next pond.

Answer:

[tex]x \geq 15[/tex]

Step-by-step explanation:

Solving an inequality is very similar to solving an equation, one uses inverse operations. The only major difference between the two is that when one multiplies or divides an inequality by a negative number, one must remember to flip the inequality sign to ensure that the inequality remains true. In this situation, such a rule does not come into play.

[tex]\frac{x}{5} - 8 \geq -5[/tex]

Inverse operations,

[tex]\frac{x}{5}-8 \geq -5\\ +8\\\\\frac{x}{5} \geq 3\\*5\\\\x \geq 15[/tex]

Answer:1,2,5,7,8 and 9. Thus, we have 6 numbers.

Step-by-step explanation:Then we want to form two-digit numbers without repetition. There are 6 number that is possible to occupy first digit, right? 1,2,5,7,8 or 9. Because it’s without repetition, so the number that have been filled the first digit cannot be the second digit. Thus, the numbers that possible to occupy second place are 5 digits.So step by step

Answer:

65.60

Step-by-step explanation:

Formula :

Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2

Solution :

Distance between two points = √(30−−22)2+(−25−15)2(30--22)2+(-25-15)2

= √522+(−40)2522+(-40)2

= √2704+16002704+1600

= √43044304 = 65.6049
