Step-by-step explanation:

1m 75cm=175cm

175/(25/7)

=49

Answer:

number of pieces is 49

Step-by-step explanation:

Length of piece is [tex]3\frac{4}{7}[/tex]

= [tex]\frac{25}{7}[/tex] cm

hence the numbers pieces,

[tex]\frac{175}{1}[/tex]

[tex]\frac{25}{7}[/tex]

⇒ [tex]\frac{(175 *7)}{25}[/tex]

⇒ = 7x7=49

Answer:

[tex]\approx10.29\text{ feet}[/tex]

Step-by-step explanation:

Please refer to the attachment.

By AA Similarity, the two triangles are similar.

Therefore, corresponding parts of them are proportional.

Therefore, we can write the following proportion:

[tex]\frac{7}{24}=\frac{3}{x+3}[/tex]

We will solve for x. Cross-multiply:

[tex]7(x+3)=24(3)[/tex]

Distribute:

[tex]7x+21=72[/tex]

Subtract 21 from both sides:

[tex]7x=51[/tex]

Divide both sides by 7. So, the value of x is:

[tex]x\approx7.2857[/tex]

However, that is only the value of x.

The shadow of the tree is (x+3).

Hence, we will need tot add 3 to our value. Therefore, the actual length of the shadow of the tree is approximately:

[tex]\approx10.2857\approx10.29\text{ feet}[/tex]

[tex]y=\frac{2}{-0.5} x[/tex]

Step-by-step explanation:

Since we know that the line starts at (0,0), it goes up by 2 and goes 0.5 to the left. I hope this was helpful & if it is correct.

To determine the vertices of the hyperbola using the equation[tex](x - 3)^2/9 - (y - 2)^2/16 = 1,[/tex] we can identify the values of a and b, where a represents the distance from the center to the vertices along the x-axis, and b represents the distance from the center to the vertices along the y-axis Therefore the correct option is D.

The given equation can be written as ([tex]x - 3)^2/3^2 - (y - 2)^2/4^2 = 1[/tex], which indicates that [tex]a^2 = 9[/tex] and[tex]b^2 = 16[/tex]. Taking the square root of a^2 and b^2 yields a = 3 and b = 4. The center of the hyperbola is (3, 2), and since the vertices are symmetrical about the center along the x-axis, the vertices can be found by subtracting and adding a from the x-coordinate of the center.

Consequently, the vertices of the hyperbola are (0, 2) and (6, 2). In summary, the vertices of the given hyperbola are located at (0, 2) and (6, 2).

Therefore the correct option is  D

Answer:

48+x=75

Step-by-step explanation:

Subtract 48 from both sides. 75-48 is equal to 27. x=27

Answer:

x [tex]\geq[/tex] 27

Sally has to complete at least 27 more hours

Step-by-step explanation:

Let x represent the number of hours she will complete next

Since students need at least 75 hours, use a greater than or equal to sign.

The total number of hours that Sally will complete can be represented by

x + 48, since she has already done 48 hours.

Use the greater than or equal to sign, and put 75 on the other side:

x + 48 [tex]\geq[/tex] 75

Next, solve the inequality:

x + 48 [tex]\geq[/tex] 75

x [tex]\geq[/tex] 27

So, Sally has to complete at least 27 more hours.

The expression for the inequality is written as a > 200.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Answer:

z is inversly proportional to r then z = k/r

zr = k

If z = 32 when r = 1.5

32(1.5) = k

48 = k

k = 48

If z = 8 then r = ?

8r = k

8r = 48

Divide to each side by 8.

r = 48/8

Answer:

The slope of this line is -2/3x.

Step-by-step explanation:

The slope can be found by getting x1 and y1 (0,3) and x2 and y2 (3,1). Once you have these you would do y2 - y1 / x2 - x1.

And the equation then is

1 - 3 / 3 - 0.  After simplifying this you get -2/3.

Answer:

[tex]y = \frac{4}{3}x + 15[/tex]

Step-by-step explanation:

•First we must find out how many inches of snow melted so we can find the slope.

15 inches - 12 inches = 3 inches

•The snow melts 3 inches every 4 hours. This statement can be rewritten as:

[tex]\frac{4}{3}[/tex]

•We know that the snow started at 15 inches so that will be our y-int.

•Now we can start combining these terms to create an equation.

[tex]m = \frac{4}{3}[/tex]

[tex]b = 15[/tex]

•All we have to do is substitute these terms for the corresponding variables.

[tex]y = mx +b[/tex] →  [tex]y = \frac{4}{3}x + 15[/tex]

[tex]y = \frac{4}{3}x + 15[/tex]
