The number number line it is seven units apart.

The absolute value larger number smaller number would be 2 - (-5). So what you do with that is keep the 2 change the subtraction sign to plus sign and change the negative 5 to positive 5. So your answer would be 7.

And smaller number to larger number would be -5 - 2. And then you do the same steps as the last one. Keep the negative five, change the subtraction sign to addition sign and make the two  negative. And that answer would be -7

2. For the number two problem you would plot the robins nest just below the top of the verticle line. the red squirrel den would be right next to the zero but a tad up. And the groundhog burrow would be below the zero mark and a little before the end of the verticle line.

Next, for groundhog burrow to red squirrel den you put the number 0.3-(-1.2)=1.5    Red squirrel den to Robin’s nest 3.6 – 0.3 = 3.3. And for the last one Groundhog burrow to Robin’s nest 3.6 – (-1.2) = 4.8.

3. you have to turn the 1 1/2 and 3/4 into 8ths. 1/2= 3*4 = 12 and for the denominator 2*4 = 8. So 12/8.

The next one is 3*2 which is 6 and 4*2=8

so now you have 12/8, 6/8, and 1/8

you have to add the points on the chart (i cant really help you on this part because i do not know how to upload picture) but you would make 24 and then you find where 12/8 would go and draw the hops but on mine the hop looks like how you would draw a rainbow but just one for the 12. Then do the same for the 6 and add 1 for the last one to make 19.

On mine I add the 12 + 6 + 1 = 19 so that is how i got mine. (sry if this a bad explination)

it should kinda look like this on the chart.

| | | | | | | | | | | | | | | | | | | | | | | | they should be spaced apart like this.

and for the last one i put cup 3 because it bigger than the amount of ingrident in the recipe. (im not sure if that one was the answer this is the only part we didnt get help on in class)

Which is the solution to the equation -3x-4=5(x+4)

Answers

Step 1. Expand

-3x - 4 = 5x + 20

Step 2. Add 3x to both sides

-4 = 5x + 20 + 3x

Step 3. Simplify 5x + 20 + 3x to 8x + 20

-4 = 8x + 20

Step 4. Subtract 20 from both sides

-4 - 20 = 8x

Step 5. Simplify -4 - 20 to -24

-24 = 8x

Step 6. Divide both sides by 8

-24/8 = x

Step 7. Simplify 24/8 to 3

-3 = x

Step 8. Switch sides

x = -3

Cynthia, Annie, and Suz went to Pepe's Pizza Palace for dinner after band practice. They shared a large pizza and each girl ordered a soda. When the bill came, they talked about how to split it up fairly. "Annie, you had three slices and a medium soda so you should pay one-third of the bill," said Suz. "Well, I'll chip in a dollar more than that," replied Annie. "And since you only had two slices and also ordered a small soda, you should only pay 20% of the bill." "That seems fair," said Cynthia. "I ate three slices and had a large soda, so I should pay the most. I'll pay the remaining $8.80." How much was the total bill for the pizza and the three sodas, and how much did each girl pay?

Answers

Final answer:

The total bill at Pepe's Pizza Palace was $16.60. Annie paid $6.53, Suz paid $3.32, and Cynthia paid the remaining $8.80.

Explanation:

To determine the total bill and how much each girl paid, we first acknowledge that Cynthia has stated she would pay the remaining $8.80. This gives us a starting point to figure out the portions of the bill that Annie and Suz will pay.

Suz suggests that Annie pays one-third of the bill and offers to pay $1 more than that amount. Suz is to pay 20% of the bill. If Cynthia pays the remaining amount, let's denote the total bill as B.

Using the information given:

Annie pays one-third of the bill plus $1: (1/3)B + $1

Suz pays 20% of the bill: 0.20B

Cynthia pays the remaining $8.80.

Add these up to get the total bill.

(1/3)B + $1 + 0.20B + $8.80 = B

Solving this equation:

0.33B + 0.20B + $8.80 - $1 = B - $1

0.53B + $7.80 = B

B - 0.53B = $7.80

0.47B = $7.80

Dividing both sides by 0.47:

B = 7.80 / 0.47

B = $16.60 (rounding to two decimal places)

Therefore, the total bill amounts to $16.60. Now to find out how much each girl pays:

Annie's portion:

(1/3)*16.60 + $1 = $5.53 + $1 = $6.53

Suz's portion:

0.20*16.60 = $3.32

Cynthia's portion is the amount she agreed to pay:

$8.80

To summarize, the total bill was $16.60. Annie paid $6.53, Suz paid $3.32, and Cynthia paid $8.80.

If one store is selling 3/4 of a bushel of apples for $9 and another story selling 2/3 of a bushel of apples for $9 which store has the better deal.


***I know the answer is calculate the $ amount first. 9 divided 3/4 total $12
9 divided 2/3 total $13.50 better deal 3/4 is cheaper...
But my question is how can identify when is division or multiplication??
I was doing multiplication but it did not work,.....why division this time?

Answers

For this case we have,

store 1:

3/4 of a bushel of apples -----------------------> $ 9

1 bushel of apples -------------------------------> x

From here the value of x is cleared, resulting in:

[tex]x =\frac{(1)(9)}{\frac{3}{4} } \\\\x = 12\\[/tex]

store 2:

2/3 of a bushel of apples -----------------------> $ 9

1 bushel of apples -------------------------------> x

From here the value of x is cleared, resulting in:

[tex]x = \frac{(1)(9)}{\frac{2}{3} }\\\\x = 13.50 \\[/tex]

Therefore it is convenient to buy apples in store 1 because it is cheaper.

Answer:

It is convenient to buy apples in store 1 because it is cheaper. A division must be made for each case because you want to find the unit cost of a product having the total cost and the amount in fraction.

A motorboat traveling a distance of 120 miles in 2 hours while traveling with the current. Against the current, the same trip took 3 hours. Find the rate of the boat in calm water and the rate of the current. Rate of boat in mph and rate of current in mph

Answers

1. The rate of the boat in calm water is 50 miles per hour.

2. The rate of the current is 10 miles per hour.

How the rates are determined:

Let:

[tex]r_b[/tex] be the rate of the boat in calm water (in miles per hour).

[tex]r_c[/tex] be the rate of the current (in miles per hour).

Given:

With the current:

Distance: 120 miles

Time: 2 hours

Speed: [tex]r_b + r_c[/tex] (since the current aids the boat)

So, the equation is:

[tex]r_b + r_c = \frac{120}{2}[/tex] = 60 (Equation 1)

Against the current:

Distance: 120 miles

Time: 3 hours

Speed: [tex]r_b - r_c[/tex] (since the current opposes the boat)

So, the equation is:

[tex]r_b - r_c = \frac{120}{3}[/tex] = 40 (Equation 2)

Step 1: Solve the System of Equations

We have the system:

[tex]r_b + r_c = 60[/tex] (Equation 1)

[tex]r_b - r_c = 40[/tex] (Equation 2)

Step 2: Add the Two Equations

Adding Equation 1 and Equation 2:

[tex]r_b + r_c + r_b - r_c[/tex] = 60 +40

[tex]2r_b[/tex] = 100

[tex]r_b = 50[/tex] (Rate of the boat in calm water)

Step 3: Substitute [tex]r_b[/tex] into one of the Equations

Substitute [tex]r_b[/tex] =50 into Equation 1:

50+[tex]r_c[/tex] = 60

[tex]r_c[/tex] = 10 (Rate of the current)

sin10° + tan40° × cos10° = ?
how to solve this??

Answers

Final answer:

To find the value of sin10° + tan40° × cos10°, calculate each trigonometric function separately, multiply tan40° by cos10°, then add sin10° to the product. The approximate result is 1.0005, but use a calculator for a precise value.

Explanation:

To solve the expression sin10° + tan40° × cos10°, we first need to calculate the individual trigonometric values. The cosine of 10 degrees (cos(10°)) is approximately 0.9848.

Next, we calculate the tangent of 40 degrees (tan(40°)). According to the provided data, tan(40°) is approximately 0.839.

Using the trigonometric identity for the sine of a sum of angles, we cannot directly simplify the expression because the addition and multiplication involve different angles. Therefore, we perform the multiplication first:

tan40° × cos10° = 0.839 × 0.9848 ≈ 0.8265

Next, we add the value of sine of 10 degrees (sin10°) to this result. Given that sin10° is approximately 0.174:

sin10° + (tan40° × cos10°) = 0.174 + 0.8265 ≈ 1.0005.

However, due to possible rounding in intermediate steps, the actual value might be slightly different when calculated using more precise values or a calculator set to the correct mode.
