1.2.B-7
Each successive figure below is made of small triangles like the first one in the sequence. Conjecture the number of small triangles needed to make a. the 100th figure? b. the nth figure?

Answer:

D

Step-by-step explanation:

Because the numbers do not comply with the like 11+6+18+21= no answer and multiplying them all didn't matter either so its none of the above

Answer:

1/12 of the pumpkin pie is left.

Explanation:

To solve this you have to add 1/6 and 3/4, but in order for you to do that, you have to change each of the fraction so they have the same denominator. To do this you have to find out what number 6 and 4 can both go into, which is 12. So since you know that 6 times 2 is 12, you would multiply two to both the numerator and denominator, and get 2/12 as the result. Next, you have to the same thing to 3/4, except since 4 times 3 is 12, you would multiply 3 to both the numerator and denominator instead, so you should get 9/12. The final thing that you have to do in order to get your answer is add 2/12 and 9/12 which would be 11/12. Since you know that 11/12 is how much Susan and Joseph ate, the remaining 1/12 is how much of the pie is left.

Answer:

The cellphone towers height is 1020 ft.

Step-by-step explanation:

This question is solved using proportions, by a rule of three.

A 10-ft post casts a 14-inch shadow.

Each feet has 12 inches, which means that a post with 10 feet will cast a 14/12 = 1.167 ft shadow. How tall is the cell-phone tower with a 119-feet shadow?

10 feet post - 1.167 ft shadow

x feet tower - 119 feet shadow

Applying cross multiplication:

[tex]1.167x = 10*119[/tex]

[tex]x = \frac{1190}{1.167}[/tex]

[tex]x = 1020[/tex]

The cellphone towers height is 1020 ft.

Answer: i think you have to add this one or divide 10 with the two to get your answer dont add that was a mistake

Answer:

Scalene and Acute

Step-by-step explanation:

We know that,

A scalene triangle is a triangle whose none of the sides are equal in measure.

A triangle is acute if all of it's angle measure below 90 degree.

Here,

The sides of the given triangle are 12.1,11,10 and 12.1≠11≠10, due to which the triangle is scalene.

All the angles of the given triangle are 51,59,70 and 51,59,70<90, Hence, the given triangle is acute

Answer: 1.510204081632653

Step-by-step explanation:

Answer:

7 ft

Step-by-step explanation:

base is b feet on each side

area of base is b² square feet

height is h feet

volume varies jointly with h and b²

V = kb²h

416 = k·78·16

k = ⅓

V = ⅓b²h

b² = 102

V = 238

h = 3V/b² = 7 ft

Answer:

D.

Step-by-step explanation:

Statistics has a lot of usage in business.

Using statistics as well as statistical tools helps in the provision of data to be used for business analysis. With available data we can get patterns in a a large database. Statistics can be used for auditing, as in question option b. For option c, statistics can be used for making business forecasts after the careful observation of trends and patterns that are in the data.

Option d does not make use of statistics. It has nothing to do with statistics neither does it have a computational feature.

Therefore, d.) questioning the executive's strategic decision is the answer to this question

Answer:

  A, C, D

Step-by-step explanation:

All three triangles can be proved congruent, so corresponding angles are congruent.

  ∆JKL ≅ ∆MNO ≅ ∆PQR

__

So, the statements that are true are ...

  A) rigid motion can map ∆JKL to ∆MNO

  C) ∆JKL can be proved congruent to ∆PQR

  D) ∠N can be proved congruent to ∠Q

_____

About the other choices

B. When triangles are congruent, there is some rigid motion that maps one to the other. It is false to say there is none such.

E. ∠L has a measure of 65° (not 55°), as do the corresponding angles in the other triangles.

Answer:

Geo pays $43.75 per month for the gym.

Step-by-step explanation:

Given that:

Membership fee = $25

Amount paid for year = $550

Let,

a be the amount he pays per month.

And there are 12 months in a year.

Total amount = Membership fee + 12 * Per month fee

550 = 25 + 12a

550 - 25 = 12a

525 = 12a

12a = 525

Dividing both sides by 12

[tex]\frac{12a}{12}=\frac{525}{12}\\a=43.75[/tex]

Hence,

Geo pays $43.75 per month for the gym.

Answer:

No, I got this answer when I did it:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Step-by-step explanation:

[tex] \frac{x}{x + x + 6} = \frac{9}{30} [/tex]

[tex] \frac{x}{2x + 6} = \frac{9}{30} [/tex]

30x = 9(2x+6)

30x = 18x+54

30x-18x = 54

12x = 54

x = 54/12

= 27/6

Answer:

The inequality is: [tex]5(x - 2) \geq 35[/tex]

The solution is: [tex]x \geq 9[/tex]

Step-by-step explanation:

Area of a rectangle:

The area of a rectangle with length l and width w is given by:

A = lw

In this question:

Width 5 feet.

Length x - 2.

For which the area of the rectangle will be at least 35 square feet

Equal or greater than 35. So

[tex]5(x - 2) \geq 35[/tex]

[tex]5x \geq 45[/tex]

[tex]x \geq \frac{45}{5}[/tex]

[tex]x \geq 9[/tex]

Answer:

11 and -11

Step-by-step explanation:

The square of 11 is 121. The square of -11 is also 121.

Answer:

Options C and F

Step-by-step explanation:

Check each answer:

6^2=36 but 36<64 so it cannot be A

8^2=64 but 64<64 (remember that even though they are equal to each other it doesn't meet the requirements of the inequality) so it cannot be B

11^2=121 and 121>64 so it can be C

-6^2=36 but 36<64 so it cannot be D (remember that squaring a number that is negative results in a positive number)

-8^2=64 but 64<64 so it cannot be E (see explanations for B and D)

-11^2=121 and 121>64 so it can be F

Therefore, the only two correct solutions are options C and F

Answer:

Can you put the figure pls?

Step-by-step explanation:

Answer:

$24

Step-by-step explanation:

First, find the cost to cover one pair of shoes.

Cost to cover one pair of shoes = surface area of the shoe box × cost per square inch

= 2(LW + LH + HW) × 0.02

L = 14 in.

W = 8 in.

H = 4 in.

Plug in the values

Cost to cover one pair of shoes = 2(14*8 + 14*4 + 4*8) × 0.02

= 2(112 + 56 + 32) × 0.02

= 2(200) × 0.02

= 400 × 0.02 = 8

Cost to cover one pair of shoes = $8

Cost to cover 3 pairs of shoes = 3*8 = $24
