Answer:

[tex]\huge\boxed{\sf x = 64 \ words}[/tex]

Step-by-step explanation:

Given that,

Memorized words = 16

These memorized words are 1/4 of the list.

Let the total words be x.

So,

[tex]\displaystyle \frac{1}{4} \ of \ the \ total \ words = 16[/tex]

Key: "of" means "to multiply" and total words = x

[tex]\displaystyle \frac{1}{4} \times x = 16\\\\Multiply \ both \ sides \ by \ 4\\\\1 \times x = 16 \times 4\\\\x = 64 \ words\\\\\rule[225]{225}{2}[/tex]

Answer:

6

Step-by-step explanation:

Input Data :

Point 1  ( x A , y A )  = (-1, 6)

Point 2  ( x B, y B )  = (5, 6)

Objective :

Find the distance between two given points on a line?

Formula :

Distance between two points =  √ ( x B − x A ) 2 + ( yB −y A ) 2

Solution :

Distance between two points =  √ ( 5 −  − 1 ) 2 + ( 6 − 6 ) 2

=  √ 6 ^2 +0^ 2

=  √ 36 + 0

=  √ 36 = 6

Distance between points (-1, 6) and (5, 6) is 6

Answer:

12

Step-by-step explanation:

If the sum of the digits of a certain two-digit number is 15 and reversing its digits increase the number by 9, then the numbers are 7 and 8

Let the two digits numbers be x and y

If the sum of the digits of a certain two-digit number is 15, then;

x + y = 15 .................... 1

If the digits are reversed and increased number by 9

10y + x = 10x + y + 9 ................ 2

From 1, x = 15 - y

Substitute into equation 1 to have:

10y + 15 - y = 10(15-y) + y + 9

9y + 15 = 150 - 9y + 9

18y = 159 - 15

18y = 144

y = 8

Since x = 15 - y

x = 15 - 8

x = 7

This shows that the numbers are 7 and 8

Answer:

∅ = 16.2602°

Step-by-step explanation:

cos∅ = adjacent / hypotenuse

Since we are dealing with right triangles, we can use trigonometry to help us solve for the missing angle.

cos∅ = 24/25

∅ = cos⁻¹(24/25)

∅ = 16.2602°

Answer:

6161 tiles

Step-by-step explanation:

The number of boxes that Amanda can cover with W square inches of wallpaper will be equal to W/2(lw + lh + wh).

Let's assume that Amanda wants to build n wooden storage boxes. All of these boxes are shaped like rectangular prisms, as shown in the image below.

She wants to cover all the sides of each box with special wallpaper. If she has a total of W square inches of wallpaper, we need to find out how many boxes she can cover. Let's solve this problem mathematically.

Mathematical Solution:

Each rectangular prism has six sides (faces). If we want to cover all the six sides of a rectangular prism with special wallpaper, we need to find the total surface area of that rectangular prism. Therefore, the surface area of each rectangular prism can be calculated by the formula:

Surface Area = 2lw + 2lh + 2wh,

where l, w, and h are the length, width, and height of the rectangular prism, respectively.

We know that Amanda has W square inches of wallpaper to cover all the boxes. Therefore, the total surface area of n boxes will be:

n × Surface Area = W.

Substituting the value of the Surface Area, we have:

n × (2lw + 2lh + 2wh) = W

2n(lw + lh + wh) = W

n(lw + lh + wh) = W/2

n = W/2(lw + lh + wh).

Answer:

[tex]5<t<6\\(5,6)[/tex]

Step-by-step explanation:

We know that the function of the height of a rocket after t seconds is:

[tex]h(t)=-9.8t^2+107.8t[/tex]

We want to find the interval of time such that the rocket is higher than 294 meters.

So, substitute 294 for h(t) and solve for t:

[tex]294=-9.8t^2+107.8t[/tex]

Just as it happens, everything is divisible by -9.8. So, divide everything by -9.8. This yields:

[tex]-30=t^2-11t[/tex]

Add 30 to both sides:

[tex]t^2-11t+30=0[/tex]

Factor. We can use -6 and -5. So:

[tex](t-6)(t-5)=0[/tex]

Zero Product Property:

[tex]t-6=0\text{ or } t-5=0[/tex]

Solve for each equation:

[tex]t=6\text{ or } t=5[/tex]

So, our answers are 5 seconds and 6 seconds.

Therefore, between the fifth and sixth second, the rocket is higher than 294 meters.

Note that at exactly the fifth and sixth second, our height is exactly 294 meters, not higher.

Therefore, we won't include 5 and 6 in our solution set.

As an inequality, this is:

[tex]5<t<6[/tex]

In interval notation, this is:

[tex](5,6)[/tex]

Answer:

x = 45 miles

Step-by-step explanation:

We can use ratios to solve

2 gallons       3 gallons

--------------  = --------------

30 miles        x miles

Using cross products

2x = 3*30

2x = 90

Divide by 2

2x/2 = 90/2

x = 45 miles

Answer:

He can travel 45 miles with 3 gallons

Step-by-step explanation:

If he traveled 30 miles with 2 gallons then that would mean each gallon lasted 15 miles, 30/2=15, therefore if there were 3 gallons he would travel 45 miles, 45/3=15

Answer:

x = -10, y = -8

Step-by-step explanation:

We will use the method of elimination to find y.

Step 1: 5x - 8y = 14

          -

           5x - 7y = 6

Step 2:  0x - y = 8

Step 3: y = -8

Now, we have to substitute the y value into one of the original equations. In this case we will use the first equation which is 5x - 8y = 14.

5x - 8(-8) = 14

5x + 64 = 14

5x = - 50

x = -10

Just to make sure we have the right values, we will substitute both values into one of the equations.

5(-10) - 7(-8) = 6

-50 + 56 = 6

6 = 6           True

5(-10) - 8(-8) = 14

-50 + 64 = 14

14 = 14         True

Both of these values work, so they are the answers.
