Answer:

\large\boxed{d_2=15\ cm}

Step-by-step explanation:

The formula of an area of a kite:

A=\dfrac{d_1d_2}{2}

d₁, d₂ - diagonals

We have A = 120 cm² and d₁ = 16 cm. Substitute:

\dfrac{16d_2}{2}=120

8d_2=120           <em>divide both sides by 8</em>

d_2=15\ cm

How do I find b in y=mx+b?​
Ainat [17]

Answer:

In the equation y = mx + b for a straight line, the number m is called the slope of the line. Let x = 0, then y = m • 0 + b, so y = b. The number b is the coordinate on the y-axis where the graph crosses the y-axis.

Today is sunday. Tom starts to read a book with 490 pages today. Sundays he reads 25 pages and on all other days he reads 4 page
mrs_skeptik [129]

Based on the information given, it can be noted that Tom will use 117 days to read the book.

How to solve a equation.

Based on the information given, we are informed that Tom starts to read a book with 490 pages today. Sundays he reads 25 pages and on all other days he reads 4 pages.

Let the number of days be represented by x. Therefore, the equation to solve the question will be:

25 + (4 × x) = 490

25 + 4x = 490

4x = 490 - 25

4x = 465

x = 465/4

x = 116.25

x = 117

Therefore, he'll use 117 days to read the book.
