I need help on this question plz

Answers

Answer 1

Answer:

Given is triangle with base = 10 cm and perpendicular height = 3 cm.

We know the formula for area of triangle is given by :-

Area = $(1)/(2)$ × (Base) × (perpendicular height)

Area = $(1)/(2)$ × (10) × (3)

Area = $(30)/(2)$

Area = 15 cm²

So, final answer is 15 cm².

What is the slope of the line represented by the equation –5x+2y= 10–5x+2y= 10 ?A)–5/2

B)–2/5

C)2/5

D)5/2

Answers

The slope of the line represented by the given equation is: A. $(5)/(2)$

Given the following equation:

$-5x+2y=10$ ....equation 1

To find t:

The standard form of an equation of line is given by the following formula;

$y = mx + b$ .....equation 2.

Where:

x and y are the points.

m is the slope.

b is the intercept.

From equation 1:

$-5x+2y=10\n\n2y = 5x + 10\n\ny = (5)/(2)x + 10$

Comparing eqn 1 and eqn 2:

Slope = $(5)/(2)$

Think you accidentally typed -5x + 2y = 10 twice.

Anyhow, let's rearrange the equation to match the equation for a line which is y = mx + b:

-5x + 2y = 10

2y = 5x + 10

y = 5/2x + 5

Now, the slope in a line is the m value. So 5/2 is the slope.

y = 5/2x + 5

28 elementary schools to 16 middle school

Answers

Answer:

$(7)/(4)$

Step-by-step explanation:

Here is the complete question: 28 elementary schools to 16 middle schools, write the ratio in simplest form.

Given ratio= elementary schools: middle schools:: 28:16

The ratio can be written as $(28)/(16)$

Now to write $(28)/(16)$ into simplest form, we need to divide both numerator and denominator by 4.

∴ elementary schools: middle schools= $((28)/(4) )/((16)/(4) )$

Hence, we get simplest ratio of elementary schools to middle schools= $(7)/(4)$
