What’s the answer and work for this? Someone please tell me

Answer:

No

Step-by-step explanation:

Figure A has an horizontal length of 2 units and a vertical length of 2 units.

Figure B has an horizontal length of 9 units and a vertical length of 7 units

Thus:

Horizontal length of Figure B / Horizontal length of figure A = 9/2

Horizontal length of Figure B / Horizontal Length of Figure A = 7/2

Thus,

9/2 ≠ 7/2

This implies that their corresponding lengths are not corresponding to each other. Therefore, Figure B is not a scale copy of Figure A.

Answer:

Soda = $4  Shirt = $18

Step-by-step explanation:

s- soda

h - shirt

2s+2h = 44 → 2

h + 3h = 30 → 1

1 * 2

2h  + 6h = 60 →3

3 - 2

4h = 16

h = $4

s = $18

b) See annex

x  =  0,5 ft

y =  2 ft   and

V = 2 ft³

Step-by-step explanation:  See annex

c) V = y*y*x

d-1) y = 3 - 2x

d-2) V = (3-2x)* ( 3-2x)* x   ⇒ V = (3-2x)²*x    

V(x) =( 9 + 4x² - 12x )*x    ⇒   V(x) = 9x + 4x³ - 12x²

Taking derivatives

V¨(x) = 9 + 12x² - 24x

V¨(x) = 0              ⇒   12x² -24x +9 = 0     ⇒  4x² - 8x + 3 = 0

Solving for x (second degree equation)

x =[ -b ± √b²- 4ac ] / 2a

we get    x₁  =  1,5       and    x₂ =  0,5

We look at y = 3 - 2x    and see that the value x₂ is the only valid root

then

x  =  0,5 ft

y =    2 ft   and

V = 0,5*2*2

V = 2 ft³

Answer:

m<JMK = 54

m<JKH = 63

m<HLK = 90

m<HJL = 27

m<LHK = 63

m<JLK = 27

Step-by-step explanation:

1. Solve for m<JMK

It is given that (<HMJ) and (<JMK)  form line (HK), meaning that they are supplementary angles. Thus, their degree measures add up to (180), using this one can form the following equation,

(<HMJ) + (<JMK) = 180

126 + (<JMK) = 180

(<JMK) = 54

2. Solve for m<JKH

It is given that the figure is a rectangle, one of the properties of a rectangle is that diagonals are congruent, and the diagonals bisect each other. This means that segments (JM) and (MK) are congruent. Hence, the triangle (JMK) is an isoceles triangle. Therefore, one can use the base-angles theorem, which states that (<MJK) is congruent to (<JKH). Since the sum of angle measures in any triangle is (180), one can form the following equation,

(<JMK) + (<MJK) + (<JKH) = 180

54 + 2(<JKH) = 180

<JKH = 63

3. Solve for m<HLK

As per its definition, the corner angles in a rectangle are always (90) degrees, this property is applicable for the given rectangle. Thus, (<HLK) = 90 degrees.

4. Solve for m<HJL

To solve for this angle, one can use similar logic as they did to solve for (<JKH).  Form the following equation and solve,

(<HMJ) + (<HJL) + (<JHK) = 180

126 + 2(<HJL) = 180

(<HJL) = 27

5. Solve for m<LHK

The vertical angles theorem states that when two lines intersect, the opposite angles are congruent. One can apply this theorem here and say (<JMK) = (<HML). Then, to solve for this angle, one can use the same logic that they used to solve for (<JKH) and (<HJL). Form the equation and solve,

(<HML) +(<LHK) + (<HLJ) = 180

54 + 2(<LHK) = 180

<LHK = 63

6.Solve for m<JLK

To solve for this angle, one can use the same logic that they used to solve for (<LHK). Form the equation and solve,

(<LMK) + (<JLK) + (HKL) = 180

126 + 2(<JLK) = 180

<JLK = 27

Answer:

y = 19

Step-by-step explanation:

19-9=10

y = 19

No, it cannot equal one because if it did the answer would be -8. If you add 10 and 9 it is equal to 19, which means that y=19.

Step-by-step explanation:

pyramid A: 16 + [tex]8\sqrt{5[/tex]

pyramid B: 400 + [tex]8\sqrt{125[/tex]

pyramid A: 4 by 4= 16 cm.

with a height of 1 and length of 2, we use pythagorean theorem to find height of other surfaces to be square root of 5. area of triangle is 1/2 bh

square root of 5 multiplied by 4 and divided by 2 is 2 root 5

multiply this by 4 sides total for 8 root 5

Add the 8 root 5 to 16

To find pyramid B: use ratio of 25:1 and multiply 16 by 25 to find 400, and root 5 to 125

Answer:

  A) t = 0.25c +25

  B) c = 52

  C) 3 weekday shifts

Step-by-step explanation:

A. The amount Ella earns is $0.25 per cupcake, so for c cupcakes, that is ...

  0.25c

In addition, she is paid $25, so her total amount she is paid is ...

  t = 0.25c +25

__

B. In order to earn $38, the number of cupcakes sold must be ...

  38 = 0.25c +25

  13 = 0.25c . . . . . . subtract 25

  52 = c . . . . . . . . . multiply by 4

Ella sold 52 cupcakes to earn $38.

__

C. On one of the average weekdays, Ella could be expected to earn ...

  t = 0.25(36) +25 = 34

Then for 3 weekday shifts, her earnings would be 3($34) = $102. (It would take Ella 3 weeks to earn $300.)

On one of the average weekend shifts, Ella could be expected to earn ...

  t = 0.25(62) +25 = 40.50

Then for 2 weekend shifts, her earnings would be 2($40.50) = $81. (It would take Ella 4 weekends to earn $300.)

Ella would earn $300 more quickly by working weekday shifts.

Answer: 47.5 ft

Step-by-step explanation:

since this is a right triangle, you can use trig to solve for x:

cos 22° = [tex]\frac{44}{x}[/tex] (cos = adjacent/hypotenuse)

x * cos 22° = 44

x = [tex]\frac{44}{cos 22}[/tex] (plug into calc)

x = 47.5 ft

Answer:

$4298.10

Step-by-step explanation:

Using the relation :

V = Pe^rt

P = 3090 ; r = 3% = 0.03 ; t = 11 years

V = 3090 * e^(0.03 * 11)

V = 3090 * e^0.33

V = 3090 * 1.3909681

V = 4298.0915

Amount in the investment after 11 years will be $4298.10

Step-by-step explanation:

Fixed Cost = $25 membership fee

Variable Cost = $0.25 per hour of play

Given n is the number of hours played and D is the total cost,

D = Fixed cost + variable cost($0.25 x n hours)
