In triangle △ABC, ∠ABC=90°, BH is an altitude. Find the missing lengths.

shtirl [24]

Answer:

HC= $\sqrt{3}$

Step-by-step explanation:

Let HC=x, it is given that AH=3HC, then AH=3x.

Since, from the given figure, ΔABC is similar to ΔBHC and ΔABC is similar to ΔABH.

Therefore, ΔABH is similar to ΔBHC, hence using the similarity conditions,

$\frac{HC}{BH}=\frac{BH}{AH}$

$\frac{x}{3}=\frac{3}{3x}$

$3x^{2}=9$

$x^{2}=3$

$x=\sqrt{3}$

Hence, HC= $\sqrt{3}$ .

A is what percent of b a= 2 ft b= 1 yd

dsp73

Answer:

$66\frac{2}{3}\%$

Step-by-step explanation:

Remember that

$1\ yd=3\ ft$

we have

$a=2\ ft\\b=1\ yd=1(3)=3\ ft$

In this problem

b represent the 100%

so

using proportion

Find out what percent of b represent a

Let

x -----> the percentage of b

$\frac{3}{100}=\frac{2}{x}\\\\x=100(2)/3\\\\x=\frac{200}{3}\%$

Convert to mixed number

$\frac{200}{3}\%=\frac{198}{3}+\frac{2}{3}=66\frac{2}{3}\%$

Substitute w = 1 and w = 3 to determine if the two expressions are equivalent

Effectus [21]

Answer:

Expressions are not equivalent

Step-by-step explanation:

Given expressions are:

$4(3w+4)\ and\ 16w+12$

Putting w=1 in both expressions

$4(3w+4)\\=4[3(1)+4]\\=4(3+4)\\=4(7)\\=28\\\\16w+12\\=16(1)+12\\=16+12\\=28$

Both expression have value 28 on w=1

Putting w=3 in both expressions

$4(3w+4)\\=4[3(3)+4]\\=4(9+4)\\=4(13)\\=52\\\\16w+12\\=16(3)+12\\=48+12\\=60$

Both expression have different values at w=3

Hence, in order for the expressions to be equivalent they both should produce same value on w=3 too.

So, it can be concluded that both expressions are not equivalent ..

1. Are the ratios, 8/12 and 10/25 proportional? Please explain. I will give brainliest for the best explanation.

Marina86 [1]

Answer:

1. No

2. 1,050 bushels of corn

Step-by-step explanation:

1. A number is proportional if it has a constant ratio to another quantity.

8/12 and 10/25 do not.

2. An acre will produce $\frac{750}{10}$ bushels of corn.

750 divided by 10 is 75. <u>This is 75 bushels per acre.</u>

Then you would multiply 75 and 14.

This equals 1,050 bushels of corn.

A town has a population of 12000 and grows at 3.5% every year. What will be the population after 7 years, to the nearest whole n

Elena L [17]

Answer:

After 7 years the population will be 15268.

Step-by-step explanation:

Given a town has a population of 12000 and grows at 3.5% every year. we have to find the population after 7 years.

As the general growth formula is

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

where A = Amount after growth

P = Original amount

r = yearly growth rate

t = no. of years

here, P=12000, r=0.035, t=7

$A=12000(1+0.035)^7$

= $12000(1.035)^7$

= $15267.35\sim15268$

Hence, after 7 years the population will be 15268.
