How do you answer this question.

Ipatiy [6.2K]

Lets write this out:-

$\frac{50}{100} + \frac{30}{100}$

To answer this we just need to add the numerators of both fractions because the denominator's are already common multiples.

$\frac{50}{100}+ \frac{30}{100} = \frac{80}{100}$

Now lets simplify $\frac{80}{100}$ .

$\frac{80/20}{100/20}= \frac{4}{5}$

So, $\frac{50}{100}+ \frac{30}{100} = \frac{80}{100}= \frac{4}{5}$

Hope I helped ya!! xD

The base of a triangle exceeds the height by 7 centimeters. If the area is 400 square centimeters, find the length of the base a

zvonat [6]

Answer:

Base = 32 cm

Height = 25 cm

Step-by-step explanation:

Area of a triangle can be calculated as:

$Area = \frac{1}{2}\times Base \times Height$

We are given that the base of triangle exceeds the height by 7 cm. This can be expressed in an equation form as:

Base = Height + 7

Lets use B to represent base and H to represent height

B = H + 7

The equation of area can be stated as:

$Area=\frac{1}{2}bh\\\\ Area=\frac{1}{2}(h+7)(h)\\\\ 400=\frac{1}{2}h(h+7)\\\\ 800=h^{2}+7h\\\\ h^{2}+7h-800=0$

This is a quadratic equation which can be solved using a quadratic equation as shown below:

$h=\frac{-7+-\sqrt{49-4(1)(-800)} }{2(1)} \\\\ h=\frac{-7+-57}{2}\\\\h=-32,25$

Since the height cannot be negative, we'll consider the positive value only i.e height is equal to 25 cm.

Therefore, the length of base will be 25 + 7 = 32 cm.

a(x+b)=4x+10 in the equation above a and b are constants. if the equation has infinitely many solutions for X, what is the value

xeze [42]

Answer:

$b= \frac{5}{2}$

Step-by-step explanation:

Given

$a(x+b)=4x+10\\ax+b= 4x+10\\$

Now we know that system has infinite solution for x

$\frac{a_1}{a_2}=\frac{b_1}{b_2}$

in above equation.

$a_1=a, a_2=4, b_1=ab,b_2=10\\$

∴ $\frac{a}{4}=\frac{ab}{10}\\\therefore b=\frac{10\times a}{4\times a}=\frac{5}{2}$

How do you Simplify :(2p^-3)^5

iragen [17]

Answer:

The final simplification is (32p^-15).

Step-by-step explanation:

Given:

(2p^-3)^5 we have to simplify.

Property to be used:(Power rule)

Power rule states that: $(a^x)^y=a^x^y$ ...the exponents were multiplied.

Using power rule.

We have,

⇒ $(2p^-3)^5$

⇒ $(2^5)(p^-3^*5)$ ...taking exponents individually.

⇒ $32(p^-^1^5)$ ... $2^5=2*2*2*2*2=32$

⇒ $32p^-^1^5$

So our final values are 32p^-15
