on a scale drawing with a scale of 1 in: 5 ft, a tree is in. tall. How tall is the actual tree?

He is buying one large tree, so subtract the cost of a large tree from the total:

1400 - 200 = 1200

He can spend 1200 on small trees.

Divide 1200 by the cost of a small tree to find how many small trees can be bought:

1200 / 150 = 8

He can buy 8 small trees.

Total number of trees = 8 small + 1 large = 9 total

955    100

Cross multiply

955x40=38200

38200÷100=382

u get 382

955 -382= 573

$573

So here are the rules with change by percentage (m = percentage in decimal form, n = original, and r = new):

Since this is a price reduction, we will be following the second rule. In this case:

[tex]40\%=0.4\\\\(1-0.4)*955=r\\0.6*955=r\\573=r[/tex]

In short, the reduced price of the computer is $573.

180°-(90°+68°)=180°-158°=22°

6

180°-22°=158°

Answer:

22° and 158°

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 angles in the triangle from 180

∠5 = 180° - (90 + 68)° = 180° - 158° = 22°

∠5 and ∠ 6 form a straight angle, thus the angles are supplementary

∠6 = 180° - ∠5 = 180° - 22° = 158°

Answer:

1) Given

2) if lines are parallel, then corresponding angles are equal

3) Substitution

4) if altenate interior angles are equal, then the lines are parallel

x is all real numbers

Step-by-step explanation:

6 + 5|2x -3| ≥ 4

The first step is to subtract 6 from each side

6 -6+ 5|2x -3| ≥ 4-6

5|2x -3| ≥ -2

Now divide each side by 5

5/5|2x -3| ≥ -2/5

|2x -3| ≥ -2/5

Absolute values are always positive.  Our absolute value is greater than a negative number.  It is always true.  X can be any number and our absolute value will still be greater than -2/5.

x is all real numbers

Answer: 81 in. (6.75 ft.) by 60 in. (5 ft.)

First, convert 27 ft. and 20 ft. to inches to make it easier to work with. This would convert like this:

27 ft. x 12 in. = 324 in.

20 ft. x 12 in. = 240 in.

This also means that the scale converts to 1/4 in. = 12 in.

Now, take your 324 in. and 240 in. and apply them to the scale.

For every 12 in. (1 ft.) in the non-scale room dimensions, there will be one 1/4 in. on the scale. That would apply like this:

324 in. (27 ft.) x

1/4 in. =81 in. [or 6.75 ft.]

240 in. (20 ft.) x

1/4 in. = 60 in. [or 5 ft.]

Answer:

Everything should simplify down to -9a-3 (your answer)

Step-by-step explanation:

Distributive property is basically multiplying the outside number into the inside parenthesis ().  Basically #(a)--->#a        or   #(a+b)---> #a+#b

Since you're not ask to solve for anything but simplify, just multiply 3 to -3a and -1.....

so 3*-3a is -9a and 3*-1 is -3      and you have 3(-3a-1)= -9a-3

Final answer:

The distributive property is a mathematical property that allows us to distribute multiplication over addition or subtraction. It helps simplify expressions and perform calculations more efficiently in algebra and arithmetic.

Explanation:

The distributive property is a mathematical property that allows us to distribute multiplication over addition or subtraction. It states that for any numbers a, b, and c, the expression a * (b + c) is equal to a * b + a * c. This property helps us simplify expressions and perform calculations more efficiently.

For example, if we have the expression 3 * (2 + x), we can use the distributive property to simplify it to 3 * 2 + 3 * x, which becomes 6 + 3x. This allows us to break down the calculations into smaller steps and avoid errors.

The distributive property is one of the fundamental properties of multiplication and is widely used in algebra and arithmetic.

Based on the information given, it can be concluded that 35% of the circle is shaded, which is equivalent to the fraction 7/20.

To understand what area of the circle is shaded, let's first calculate how much is not shaded:

First area: 1/4 = 0.25

Second area: 2/5 = 0.4

Total of the area that is not shaded: 0.65

The total area shaded: 1 -0.65 = 0.35

This means that the total shaded is 0.35. Now, let's convert 0.35 to a fraction:

Answer:

van : 12 miles per gallon

cabinets: 3 cabinets a day

retail job for $500

Step-by-step explanation:

van: 240 miles/20 gallons = 12 miles per gallon

cabinets: 24/8= 3

jobs: $500 for 40 hours and $12 times 40 hours gets you $480

first job pays $20 bucks more

Ques 1)

A van travels 240 miles on 20 gallons of gas.

Answer:

Essence is 140 flyers per hour

Raizon is 80 flyers per hour

Step-by-step explanation:

In essence (if you see what I did there) a unit rate (strictly in this context) is how much work is done for 1 hour of time. To find this, we simply divide the number of flyers by the number of hours of worked.

So, for Essence:

[tex]\frac{420}{3} = 140[/tex]

The units for this problem will be flyers per hour. So, Essence has a unit rate of 140 flyers per hour.

For Raizon:

[tex]\frac{640}{8} = 80[/tex]

Raizon has a unit rate of 80 flyers per hour.

The distance between the points (-3,-4) and (5,4) is approximately 11.31 units, and the distance between the points (-3,5) and (0,1) is exactly 5 units.

To find the distance between two points in a plane, you can use the distance formula derived from the Pythagorean Theorem, which is

d² = (x2 - x1)² + (y2 - y1)²

Let's calculate the distances for the given pairs of points.

Distance between (-3,-4) and (5,4)

d² = (5 - (-3))² + (4 - (-4))²

d² = (8)² + (8)²

d = 64 + 64 = 128

d = √128

≈ 11.31

Distance between (-3,5) and (0,1)

d² = (0 - (-3))² + (1 - 5)²

d² = (3)² + (-4)²

d = 9 + 16 = 25

d = √25

d = 5

C: 0.25  

Step-by-step explanation:

We will use conditional probability formula to solve our given problem.

[tex]P(B|A)=\frac{P(\text{A and B})}{P(A)}[/tex], where,

[tex]P(B|A)[/tex]= Probability of event B, given probability of event A.

[tex]P(\text{A and B})[/tex]= Probability of event A and event B.

[tex]P(A)[/tex]= Probability of event A.

Let us substitute our given values in conditional probability formula.

[tex]P(B|A)[/tex]= Probability that a student plays a sport given that student is a senior.

[tex]P(\text{A and B})[/tex]=The probability that a student is a senior and plays a sport = 0.05.

[tex]P(A)[/tex]= Probability that a student is a senior = 0.20.

[tex]P(B|A)=\frac{0.05}{0.20}[/tex]

[tex]P(B|A)=\frac{1}{4}[/tex]

[tex]P(B|A)=0.25[/tex]

Therefore, the probability that a randomly selected student plays a sport, given that the student is a senior will be 0.25 and option C is the correct choice.

Answer:

probability that a randomly selected student plays a sport, given that the student is a senior is 0.25

Step-by-step explanation:

Let, A be an event that a student is senior.

Probability can be given as , p(A) = 0.20

B be the event where student plays a sport

Probability can be given as , p(B) = 0.15

We have given that the probability of a student is a senior and plays a sport is 0.05.

i.e p(A∩B) =  0.05

We need to find the probability that a randomly selected student plays a sport, given that the student is a senior i.e p(B/A) .

Use the formula: p(B/A) = p(A∩B) / p(A)

Plug corresponding values to get p(B/A).

p(B/A) = p(A∩B) / p(A)  = 0.05 /0.20

p(B/A) = 0.25 , this is the answer

Answer: 24% of all employees attend night school.

Step-by-step explanation: If 40% of all employees are men and 30% of the men attend night school, we can multiply 0.40 by 0.30 to get the percentage of men who attend night school: 12% or 0.12. To find the number of women who attend night school, multiply 0.20 by 0.60(assuming percentage of men and women add up to 100%) to get 12%. Add 12% and 12% to get 24% of all employees attend night school.
