Answers

Answer 1

Answer:

75

Step-by-step explanation:

125 × 0.40 = 50

125 - 50 = 75

Answer 2
HII!!HERE'S YOUR ANSWER ANSWER= 75

STEP BY STEP EXPLANATION:

Decrease number by 40% of its value.

Percentage decrease = 40% × 125

New value

125 - Percentage decrease

125 - (40% × 125)

125 - 40% × 125

(1 - 40%) × 125

(100% - 40%) × 125

60% × 125

60 ÷ 100 × 125

60 × 125 ÷ 100

7,500 ÷ 100

=75

In the 48 years between 1842, the average rate of erosion at horseshoe falls was 33 divided by 50 metre per year. In the 22 years between 1905 and 1927 the rate of erosion was 7 divided by 10 meter per year . Approximately how much total erosion occurred during these two time periods

Answers

Answer:

47. 08 meters

Step-by-step explanation:

Given that:

In 48 years between 1842 :

Rate of erosion = 33/50 meters per year

Between 1905 - 1927 (22 years)

Rate of erosion = 7/10 meters per year

Approximately how much total erosion occurred during these two time periods ;

Total erosion that occured within 1842:

Rate of erosion * number of years

(33/50)m * 48

0.66 meters * 48

= 31.68 meters

Total erosion that occured between 1905 - 1927:

Rate of erosion * number of years

(7/10)m * 22

0.7 meters * 22

= 15.40 meters

total erosion which occurred during these two time periods ;

31.68 meters + 15.40 meters

= 47.08 meters

The perimeter of a rectangular parking lot is 312m .
If the length of the parking lot is 95 m, what is its width?

Answers

That 160m is the length (95m) plus the width; so the width is 160-95 = 65m.

Answer:

61 meters

Step-by-step explanation:

The perimeter of a rectangle is 2l + 2w, l being the length and w being the width. Substitute the known value into the equation and solve:

312 = 2(95) + 2w

312 = 190 + 2w

122 = 2w

w = 61

Nancy has a 3.5-pound bag of birdseed. She uses 3/4 of the bag to fill a bird feeder in her garden. Then, she puts 0.25 pounds in a dish to give to her pet canaries. How much birdseed does she have left?

Answers

Answer:

0.625lb bag of bird seeds

Step-by-step explanation:

She starts with a 3.5 lb bag,

Then she uses 3/4 of the bag, so find the remaining amount in the bag, which would be 1/4 of the original weight;

1/4 * 3.5

= 1/4 * 7/2

= 7/8

Then she removes 0.25 lbs of weight, hence take away 0.25 (the amount removed) from 7/8 (the current weight of the bag).

7/8 - 0.25

= 7/8 - 1/4

= 7/8 - 2/8

= 5/8

So she has a 5/8lb bag of bird seeds or a 0.625lb bag.

c) The solutions of y=ax*2+ bx + c = 0 are

A: both negative
B: both positive
C: one negative and one positive

Answers

Answer:

A, A and A

Step-by-step explanation:

Given

y = ax² + bx + c

• If a > 0 then minimum vertex

• If a < 0 then maximum vertex

Here the vertex is a maximum, thus a < 0 , that is negative → A

The value of c is the y- intercept

The graph crosses the y- axis below the y- axis, thus c is negative → A

The solutions to ax² + bx + c = 0 are the values of x on the x- axis where the graph crosses the x- axis.

The graph crosses the x- axis to the left of the y- axis , thus

Both solutions are negative → A

Answers

Answer:

I believe the answer is -28

Step-by-step explanation

I gotchu bro

The answer is -28 because Liana starts at 25 below sea level (which is the same thing as -25) If she rises 9 feet, then you know to add because she is going up so your just gonna add. Next she descends 12 feet, so she went down, so subtract. So i know the answer is going to be -28 because -25+9 is -16, then imma subtract -16 and 12 so, -16 - 12= -28. There ye go

You are pouring 50 pounds of sand into a wagon. The linear function y= 10x represents the weight y (in pounds) of the sand in the wagon after you have poured x bags of sand into the wagon. Which graph represents the situation?​

Answers

Answer:

You have 50 lb of sand, and you are pouring this into a wagon.

We have the relationship:

y = 10lb*x

Where x is the number of bags of sand that you poured into the wagon.

We know that in total, you have 50 lb of sand, then let's find the domain of this function (Domain is the set of the possible values of x)

The minimum will be when x = 0, you poured 0 bags at this point.

And the maximium will be when y = 50lb

y = 50lb = 10lb*x

     50lb/10lb = x = 5

Then the domain is 0 ≤ x ≤ 5

Then we only will graph this in that range of values.

The graph will be something like:

Answer:

[tex]h(-6) = -457[/tex]            

Step-by-step explanation:

Given the function

[tex]h(x)= 72 x-25[/tex]

Put [tex]h = -6[/tex] to in the function

[tex]h(x)= 72 x-25[/tex]

[tex]h\left(-6\right)=\:72\left(-6\right)-25[/tex]

           [tex]=-432-25[/tex]

           [tex]=-457[/tex]

Therefore,

[tex]g\left(2\right)\:=\:5\left(2\right)^2\:+\:4\left(2\right)\:-\:3[/tex]
