Nonsense Answer = Report
Innocent Answer but no Answer = Report
Answer with Solution = Heart, 5 Star, and Brainliest

Answers

Answer:

A = 47

B = 49

Step-by-step explanation:

Let the two consecutive odd integers be A and B

We know that B = A + 2, and that A is odd.

We are also told that

3A - 92= B

Use this last expression for B in the first equation:

B = A + 2

3A - 92 = A + 2

2A = 94

A = 47

B must therefore be 47 + 2 = 49

Check:

1)  A + 2 = B?  YES

2)  3A - 92= B?

    3*47 - 92 = 49?

      141 - 92 = 49   YES

3) Are they both odd consecutive integers?  YES

     

A = 47

B = 49

Today, Ravi burned 1005.7 calories while exercising. Yesterday, he burned 138 calories. How many more calories did Ravi burn today than yesterday?

Answers

Answer:

Ravi burned 867.7 more calories today than he did yesterday.

Step-by-step explanation:

To find how many more calories Ravi burned today than he did yesterday, subtract the number of calories he burned yesterday (138) from the number of calories he burned today (1005.7). This will give us the number 867.7, which is the solution to the problem.

To check this math, we can add 867.7 to 138, which will give us 1005.7, the number of calories Ravi burned today.

Savannah is deciding between two parking garages. Garage A charges an initial fee of $9 to park plus $1.50 per hour. Garage B charges an initial fee of $4 to park plus $2.50 per hour. Let A A represent the amount Garage A would charge if Savannah parks for t t hours, and let B B represent the amount Garage B would charge if Savannah parks for t t hours. Graph each function and determine which garage would be cheaper if Savannah needs to park for 6 hours.

Answers

Answer:

A = 10 + 3t

B = 3  + 4t

if  t = 12 , then A = 10 + 3(12) = $46,  B = 3 + 4(12) = $51.

So Garage A is cheaper for 12 hours

A farmer harvests 850kg of parsnips.30% go to the local market and 50% go to a local supermarket.What mass of parsnips are left?

Answers

Answer:

170 kg. of parsnips are left

Step-by-step explanation:

Given:

850 kg. of parsnips

30 % to the local market

50 % to a local supermarket

Solution:

First, add the two percentages.

30 + 50 = 80%

That means 80 % of parsnips mass go to the markets.

Now let's find the mass of delivered parsnips.

Change 80% to decimal form.

80% = 0.8

Now multiply it by 850 kg.

850 x 0.8 = 680

The delivered parsnips mass is 680 kg.

Now to find the mass of parsnips left, subtract 680 to 850

850 - 680 = 170 kg.

170kg. of parsnips are left.

Two shops sell baked beans in different sized tins. Calculate the price per 1.25 kg for shop B. Give your answer in pence.


Shop A) 1.25kg for £4.85

Shop B) 250g for £0.88

Answers

Step-by-step explanation:

come on !

250g = 0.250kg = 0.25kg

now compare 1.25 kg with 0.25kg.

how many times of 0.25 is 1.25 ?

it is the same as 25 to 125.

5 times (4 times 25 is 100, and then one more time).

so, you need to multiply also the price by 5 to get the price per 1.25kg.

so, 0.88×5 = £4.40 = 440 pence per 1.25kg.

The University of Washington Huskies tried throwing one of the longest Hail Marys in history—about 73 yards! For this pass, the ball's height over time was modeled by the function h(t) = -16t2 + 64t + 6, where was the height in feet and was the time in seconds. a) How long does it take for the football to reach its maximum height? b) What is its maximum height? c) How long will the football be in the air? It takes a good college football player about 8 seconds to run 73 yards. If the quarterback waited 4 seconds after the snap, does the receiver have a chance of catching the ball?

Answers

Answer:

See below

Step-by-step explanation:

Given function:

h(t) = -16t² + 64t + 6

a)

The maximum height is the vertex. The x-coordinate of the vertex is -b/2a:

t = - 64/2*(-16) = 2

It takes 2 seconds

b)

Maximum height is at vertex:

h(2) = -16(2²)  + 64(2) + 6 = 70 yd

c)

The ball is in the air between zero's of the equation or approximately double the time it reaches the vertex:

2*2 = 4 seconds

The receiver doesn't have a chance to catch the ball, since the ball is only 4 seconds in the air.

Given $P(10,12)$ and $Q(20,36)$, find the coordinates of a point whose distance from both $P$ and $Q$ is exactly $13.$

Answers

The coordinate of a point whose distance from both P and Q is exactly 13 is; (15, 24)

The distance between points, P and Q can be evaluated by the Pythagoras theorem as follows;

Distance, PQ = √(20-10)² + (36-12)²

PQ = √(100+576)

PQ = √676

PQ = 26.

Therefore, a point whose distance from both P and Q is exactly 13 is the midpoint of PQ.

Therefore,

x = (20 + 10)/2

x = 15

y = (36 + 12)/2

y = 24.

The coordinate of a point whose distance from both P and Q is exactly 13 is; (15, 24)

the perimeter of an equilateral triangle is 14.4 cm. Find out the length of the side of that triangle in decimal fraction​

Answers

Answer:

Side length = 4.80 cm

Step-by-step explanation:

Given the perimeter of an equilateral triangle, 14.4 cm:

An equilateral triangle has three congruent sides.

Since a triangle has three sides, and the sum of those sides represent the perimeter.  We can assume that each side of the triangle represents a third (⅓) of the perimeter.

Perimeter of an equilateral triangle = side + side + side = 3(side)  

Perimeter = 14.4 cm

[tex]\displaystyle\mathsf{side=\frac{14.4\:cm}{3}=4.80\:cm}[/tex]

Therefore, the length of each side of an equilateral triangle is:  4.80 cm.

Answer:

B

Step-by-step explanation:

Look at the expression inside the log( ).  Work from the outside in, so to speak.  First, there's a quotient (the cube root divided by 3x).

[tex]\log \left( \frac{\sqrt[3]{2-x}}{3x} \right) = \log\left(\sqrt[3]{2-x}}\right) - \log{3x}[/tex]

The cube root can be written using a rational exponent.

Use the exponent property to move the exponent 1/3 out.
