Hello Love!

A good estimate would be 15 or 16 dollars left

Hope this helps!

Answer:

$15.98

Step-by-step explanation:

45.12-7.89=37.23

37.23-21.25=15.98

Answer:

-20 feet

Step-by-step explanation:

change in depth = number of feet below the surface + number of depth on the surface

Because the submarine is below surface, a value of -30 would be given

-30 + 10 = -20 feet

Answer:

10.19 cubic yards

Step-by-step explanation:

8*4=32

32 divided by 3.14= 10.19

Complete question :

The line plot shows the weights of packages of meat that members of a club bought. The meat will be mixed with vegetables to make stew for a club dinner. Each serving of the stew contains 1/4 pound of meat. How many servings of the stew can the club make?

Answer:

36 servings

Step-by-step explanation:

From the plot ; we take the sum of total weight of meat packages :

(5/8 * 2) + 6/8 + 1 + (9/8 * 3) + 10/8 + 11/8

10/8 + 6/8 + 8/8 + 27/8 + 10/8 + 11/8 = 72 / 8 = 9 meat packages

Each serving of meat = 1/4

Number of servings the club can make :

Total meat package / pound of meat per serving

(9 ÷ 1/4)

9 * 4/1

= 36 servings

Answer:

36 hope this help

Area of circle:

Answer:

x = 64

Step-by-step explanation:

The 3 angles on the right lie on a straight line and sum to 180° , that is

90 + x + 26 = 180

x + 116 = 180 ( subtract 116 from both sides )

x = 64

Answer:

64

Step-by-step explanation:

You have to do 90 - 26, which will then give you the answer 64

Double check it: 26 + 64 = 90.

Answer:

it would be 18 in 1 minute

Answer:

4 mph

Step-by-step explanation:

Let :

Boat speed = 20 mph

speed of current = x mph

Distance against current = 2 miles

Distance with current = 3 miles

speed against current will be ; 20 - x

speed with current will be ; 20 + x

Time =distance / speed against time against = time with current

Solving Mathematically ;

2/(20-x )=3/(20 +x)

2(20+x )= 3( 20-x )

40+2x = 60-3x

3x +2x=20

5x=20

x = 20 / 5

x = 4 mph

Speed of current = 4 mph

Answer:

Dropdown 1: is 20

Dropdown 2: is 10

Step-by-step explanation:

The diameter is twice the length of the radius, so multiply 2 by 10 to get 20 as the diameter. Line CO has the same length as the radius, so it is 10.

Answer:

1/36

Step-by-step explanation:

Attached is a chart showing the 36 possible outcomes for rolling 2 number cubes.  The sum of the two cubes is 12 in only one of the outcomes (both sixes).  The probability is 1/36.

Answer:

His paycheck was $62.

Step-by-step explanation:

3/4 x = 46.5

x = 46.5 * 4/3

x = 62

Equation: 3/4 x = 46.5

Solution: x = 62

Answer: n= -9

Step-by-step explanation:

5n-7=-52

5n = -52+7

5n=-45 (divide both sides)

n= -9

Answer:

A = 60 and B = 30  

Now, A + B = 60 + 30 = 90  

Also, A – B = 60 – 30 = 30  

sin (A + B) = sin 90 = 1  

sin A cos B + cos A sin B = sin 60 cos 30 + cos 60 sin 30

Answer:

34.226

Step-by-step explanation:

10.9 ÷ 2 = 5.45

C = 2πr

2 × 5.45 × 3.14

34.226

Answer:

Number of cookies sold is 2000 and number of cupcakes sold is 1500

Step-by-step explanation:

Let number of cookies be [tex]x[/tex]

and number of cupcakes be [tex]y[/tex] so

[tex]x+y=3500[/tex]

Cost of one cookie is $0.75

Cost of one cupcake is $2

[tex]0.75x+2y=4500[/tex]

[tex]x+y=3500[/tex] [tex]\times 2[/tex]

[tex]2x+2y=7000[/tex]

[tex]-1.25x=-2500\\\Rightarrow x=\dfrac{2500}{1.25}\\\Rightarrow x=2000[/tex]

[tex]y=3500-x=3500-2000\\\Rightarrow y=1500[/tex]

Number of cookies sold is 2000 and number of cupcakes sold is 1500.

Answer:

It's the second one

Answer:

Step-by-step explanation:

Remark

The ratios are certainly correct but that doesn't mean that they show similarity. SSA is a very dangerous proposition to use. Redraw triangle DEF of that DF is going to upwards to your right hand side. Make E as it was before. Why isn't this right?

It isn't right because E has gone from being an acute angle to an obtuse angle (an angle larger than 90 but less than 180).

The ratios are still true, but the angles do not match. So the whole answer is incorrect.

Answer: 17/19

Step-by-step explanation:

Number of red rocks = 6

Number of orange rock = 1

Number of blue rocks = 4

Number of white rock = 1

Number of yellow rocks = 7

Total number of rocks = 19

Probability of not getting a orange the first time will be (1 - 1/19) = 18/19.

Probability of not getting an orange the second time will be: (1 - 1/18) = 17/18

Probability of not getting an orange on both occasion will be:

= 18/19 × 17/18

= 17/19

I'm not sure if this is right, but I got 3/4. (0.75 as a decimal) I hope this helps!

Step-by-step explanation:

Answer:

x = 95°

y = 147°

z = 128°

Step-by-step explanation:

z = 180 - 52 = 128°

x: first find the remaining angle in the big triangle, 180 - (45 + 50) = 85°

x = 180 - 85 = 95°

y: first find the remaining angle in the small triangle, 180 - (95 + 52) = 33°

y = 180 - 33 = 147°
