The area of a base is found by doing the formula
1/2bh
Meaning base×height then divided by two
So
4×8=32
32/2=16

The area of this triangle is 16sq meters

Hello!

You can break this down

If she added 8 to the number

x + 8

Multiplied the sum by 2

2(x + 8)

it would equal 6

the germination rate for zinnia seeds is 78%. this means that 78 out of every 100 seeds will sprout and grow. if james wants 60

Harlamova29_29 [7]

Answer: 77 seeds

Step-by-step explanation:

Given: The germination rate for zinnia seeds =78%

Let x be the total number of seeds he planted, then

The seeds germinated= 78% of x

⇒The seeds germinated= 0.78x

If James wants 60 zinnia plants for his yard, then it will give the equation

$0.78x=60\\\Rightarrow\ x=\frac{60}{0.78}\\\Rightarrow\frac{6000}{78}\\\Rightarrow\ x=76.92307\aprrox77$

Hence, he should plant 77 seeds .

The population of a colony of mosquitoes obeys the law of uninhibited growth. If there are 1000 mosquitoes initially and there a

STatiana [176]

Answer:

24761 mosquitoes

5.4 days

Step-by-step explanation:

Let the equation that shows the population of the mosquitoes after x days,

$A=P(1+r)^x$

Where,

P = Initial population,

r = rate of increasing per day,

Here, A = 1000, when x = 0,

$1000=P(1+r)^0\implies P = 1000$

A = 1900 when x = 1,

$1900 = P(1+r)^1\implies 1900 = 1000(1+r)\implies 1.9 = 1 + r\implies r = 0.9$

Thus, the required function that represents the population after x days,

$A=1900(1+0.9)^x=1900(1.9)^x$

If x = 4,

The number of mosquito after 4 days,

$A=1900(1.9)^4 = 24760.99\approx 24761$

If A = 60,000,

$60000 = 1900(1.9)^x$

$\frac{600}{19}=1.9^x$

Taking log both sides,

$\log(\frac{600}{19})=x\log 1.9$

$\implies x = \frac{\log(\frac{600}{19})}{\log 1.9}=5.378\approx 5.4$

Thus, there will 60,000 mosquitoes after 5 days.
