Answer:

The field will not fit

Step-by-step explanation:

To find the angle, we will use cosine rule;

c² = (a² + b² - 2abcosC)

C in this case is θ

Thus;

15² = (8² + 20² - 2(8 × 20)cos θ)

225 = (64 + 400 - 320cos θ)

464 - 225 = 320cos θ

cos θ = 239/320

θ = cos^(-1) 0.7469

θ = 41.68°

Thus angle is not less than 40° as recommended. Thus, the field will not fit.

Answer:

  B.  2,022

Step-by-step explanation:

The student/faculty ratio tells you the total number of students in the school is ...

  (15 students/teacher)×(179 teachers) = 2685 students

If 663 of those are first-year, then the number of upper-level students is ...

  upper-level students = total students - first-year students

  upper-level students = 2685 -663 = 2022

The total number of upper-level students is 2,022.

Answer:

C

Step-by-step explanation:

i it has to be less than gems in more than susans, Jim is making 8.25 per hour, and Susan is making 7.50 per hour.

so the only possible answer would be 7.75

hope this helps!!!

Answer:

C.

Step-by-step explanation:

Jim earns $8.25 every hour

Susan earns $7.5 every hour

So Pierre's hourly rate has to be more than $7.5 but less than $8.25, so therefore Pierre's hourly rate is $7.75 because it is less than $8.25 but more than $7.5

Answer:

10.

bag a is lighter than bag b

bag b is lighter than bag c

so bag a is lighter that bag c

Step-by-step explanation:

... sorry i dont know #11, but hope this helps

Answer:

10.

Bag A is LIGHTER than Bag B

Bag B is LIGHTER than Bag C

So, Bag A is LIGHTER than Bag C

11.

pear is the heaviest, and the strawberry is the lightest

Step-by-step explanation:

This is really simple! Looking at the weight scale, the heavier object always goes lower than the lighter object. Knowing this, we can figure out which is heavier and which is lighter.

10.

Bag A is LIGHTER than Bag B

Bag B is LIGHTER than Bag C

Looking at these we can infer that bag c is heavier than both.

So, Bag A is LIGHTER than Bag C

11. The pear falls lower than the apple, meaning it is heavier. The apple falls lower, meaning is it heavier than the apple. We can infer that the pear is the heaviest, and the strawberry is the lightest

Hope this helps!!

Answer:

The interest is $756.

The balance is $2,556.

Step-by-step explanation:

I = Prt

I = $1,800 * 0.07 * 6

I = $756

The interest is $756.

$1800 + $756 = $2,556

The balance is $2,556.

The expression is constant, which means it can be rewritten with a factor of  x^ 0 . The degree is the largest exponent on the variable.  0

2.48 - 1.25 = 1.23

Answer:

AT=48.9

Step-by-step explanation:

Formula:

step 1; Aʟ = P ʙᴀsᴇ × Ap

2

step 2; Aᴛ = Aʟ + Aʙᴀsᴇ

Ap= 7cm

Abase= 6.9cm² P️= a + b+ c

length side️=4cm

AL = (4+4+4) × 7

2

= 12 × 7

2

= 84 ÷2

AL = 42

AT = AL + Abase

= 42 + 6.9

AT = 48.9 cm

Answer:

If I understand the definitions correctly,

"surface area" would be the total of all the areas of an object, while "lateral" surface area would exclude the base

so the surface area of a square pyramid

= area of the square base + 4(area of the triangle)

That's my "formua".

In both #1 and #2 you then give dimensions H, W, and L without defining them. If the base is square, how come we have different (W)idths and (L)engths

in #3 Diameter = 8, thus radius = 4

height = 7

Thus slant height of cone = √(4^2 + 7^2) = √65

surface area = πr(r+√(h^2+r^2)

= 4π(4 + √65) = appr 151.58

or surface area = πr^2 + πrs, where s is the slant height

= π(16) + π(4√65) = 151.58

I got the same answer using 2 established methods, none of the answers given match that.

Answer:

viii. 2x(1 - 2x)(1 + 2x)(1 + 4x²)

ix. 4xy

Step-by-step explanation:

viii. 2x - 32x⁵

= 2x(1 - 16x⁴)

= 2x(1² - (4x²)²)

= 2x(1 + 4x²)(1 - 4x²) ( a² - b² = (a + b)(a - b))

= 2x(1 + 4x²)(1² - (2x)²)

= 2x(1 + 4x²)(1 - 2x)(1 + 2x)

ix. (x+y)² - (x - y)²

= (x+ y + x - y)( x + y - x + y)

= 2x x 2y

= 4xy

Answer:

23 or 19

Step-by-step explanation:

15+8= 23

23-4= 19

i added 15 and 8 because if you were to flatten the triangle it would be next to the base, so i added it. I subtracted 4 because side C doesn't look like it is is about 23 ft. it could be 20 too.

i am not exactly sure. sorry if you get it wrong. I am so sorry if i got it wrong.
