Answer:

2 1/3 hours or 2 hrs, 20 min

Step-by-step explanation:

1 5/6 + 1/2

make mixed number into improper fraction and change 1/2 to 3/6

11/6 + 3/6 = 25/6

14/6 equals 2 2/6 which simplifies to be 2 1/3 or 2 hrs, 20 min

Answer:

(6, 3)

Step-by-step explanation:

Note that the opposite side of parallelogram are congruent, hence;

Jk = LM

2y + 3 = 5y - 6

2y - 5y  =-6 - 3

-3y = -9

y = 9/3

y = 3

Similarly;

KL = JM

8x – 10 = 3x+20

8x - 3x =  20 + 10

5x = 30

x = 30/5

x = 6

Hence (x,y) is (6, 3)

Answer:

B.

Step-by-step explanation:

Answer:

it's answer is 73°

Step-by-step explanation:

< DCB = 50°

< ACB = x

< CAB = 57°

< ABC = < DCB = 50° {Being alternate angles }

Now

x + 50° + 57° = 180° { being sum of angles of triangle }

x + 107° = 180°

x = 180° - 107°

Therefore x = 73°

Hope it will help :)❤

Answer:

38°

Step-by-step explanation:

The measure of angle NPM is 38°.

➠ ∠MPJ + ∠LPM = 180°

➠ ∠MPJ + 90° = 180°

➠ ∠MPJ = 180° – 90°

➠ ∠MPJ = 90°

∠NPM = ∠MPJ – ∠JPN

➠ ∠NPM = 90° – 52°

➠ ∠NPM = 38°

Answer: 2 : 50 pm

Step-by-step explanation:

If Jan took a break at 3:05 pm and she had been jumping rope for 15 minutes before that, to find the time she started jumping rope, subtract 15 from the current time:

= 3:05 - 15

= 2:50 pm

Jan started jumping rope at 2 : 50 pm

Answer:

[tex]V_d=976.9ft[/tex]

Step-by-step explanation:

From the question we are told that:

Height of cylinder h_1=114 feet

Diameter d=1

Length of triangular prism [tex]l_2=34ft[/tex]

Width of triangular prism  [tex]w_2=34ft[/tex]

Height of triangular prism [tex]h_2=1 ft[/tex]

Generally the equation for Volume of the cylinder is mathematically given by

 [tex]V_c=\pir^2h[/tex]

Where

 [tex]r=d/2\\r=0.5[/tex]

Therefore

 [tex]V_c-=\pi*0.5*114[/tex]

 [tex]V_c=57\pi[/tex]

 [tex]V_c=179.1ft[/tex]

Generally the equation for Volume of a Rectangular prism is mathematically given by

 [tex]V_r=whl[/tex]

 [tex]V_r=34*34*1[/tex]

 [tex]V_r=1156feet[/tex]

Generally the equation for Volume difference  is mathematically given by

 [tex]V_d=V_r-V_c[/tex]

 [tex]V_d=1156-179.1[/tex]

 [tex]V_d=976.9ft[/tex]

Answer:

B. 6%

Step-by-step explanation:

Answer:

6%

Step-by-step explanation:

Her 24 monthly payments total 24 x $56 = $1344

That means that $1344 - $1200 = $144 is just interest.  What percent is this of her loan amount?  Divide to find out:

144 / 2400 = 0.06 = 6%

Answer:

The total area is 594cm.²

Step-by-step explanation:

The top and bottom each have a length of 36 cm.

Blue side:

36/3= 12cm. (36/3 for the length of one side of a blue square)

12*12= 144cm.² (area of one blue square)

144*3= 432cm.² (area of all the blue squares)

Orange side:

36/8= 4.5cm. (the length of one side of an orange square)

4.5*4.5= 20.25cm.² (the area of one orange square)

20.25*8= 162cm.² (the area of all the orange squares)

Total area:

432+162= 594 cm.²

I hope this makes more sense, have a great day :D

Answer:

B

Step-by-step explanation:

Using the graph, we pick a convenient point: (20, 180)

This point means that for 20 hours of work, Vincent is paid 180 dollars. In fraction form, we can write 20hrs/180 dollars. If we simplify the fraction by dividing both the numerator and denominator by 20 we get 1/9 AKA 1hr/9 dollars. So in 1 hour, Vinnie is paid $9.00

Have a good rest of your day

Answer:

(a) PR = 55.2 cm

(b) RT = 19.7 cm

(c) <RPT = [tex]20.8^{o}[/tex]

Step-by-step explanation:

(a) to determine the value of PR, apply the Pythagoras theorem to PQR.

PQ = 45, and SP = QR = 32. So that;

[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]

[tex]/PR/^{2}[/tex] = [tex]45^{2}[/tex] + [tex]32^{2}[/tex]

          = 2025 + 1024

          = 3049

PR = [tex]\sqrt{3049}[/tex]

     = 55.218

PR = 55.2 cm

(b) To determine RT, apply the appropriate trigonometric function to QRT.

Let RT be represented by x, so that;

Sin [tex]38^{o}[/tex] = [tex]\frac{x}{32}[/tex]

x = 32 * Sin [tex]38^{o}[/tex]

  = 32 * 0.6157

x = 19.7024

RT = 19.7 cm

(c) To determine <RPT, let the angle be represented by θ.

Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]

        = [tex]\frac{RT}{PR}[/tex]

Sin θ = [tex]\frac{19.7024}{55.218}[/tex]

         = 0.3568

θ = [tex]Sin^{-1}[/tex] 0.35568

  = [tex]20.84^{o}[/tex]

Thus, <RPT = [tex]20.8^{o}[/tex]

Answer:

r = 2

Step-by-step explanation:

2(8r + 5) = 24 + 9r

16r + 10 = 24 + 9r

16r - 9r = 24 - 10

7r = 14

r = 2

Divide the triangle to 2 (See attachment)

Considering one of the triangles, we have:

[tex]l^2 = 4^2 + 9^2[/tex]

[tex]l^2 = 16 + 81[/tex]

[tex]l^2 = 97[/tex]

Take square roots

[tex]l = \sqrt{97[/tex]

[tex]l = 9.8488[/tex]

[tex]l = 10[/tex] --- approximated

Answer:

2 blue marbles;

4 yellow marbles;
