Answer:

if the ratio is 7/10 then do 10/400 and it will be 28 days

Step-by-step explanation:

Answer:

Elga is 32 years old.

Step-by-step explanation:

Let Alvin's age = A

Let Elga's age = E

Alvin is 10 years younger than Elga, so A = E - 10

The sum of their ages is 54, so A + E = 54

Replace the A in the second equation with E - 10, then solve for E.

A + E = 54 becomes (E - 10) + E = 54

Combine like terms

2E - 10 = 54

Add 10 to both sides

2E = 64

Divide both sides by 2

E = 32

Answer:

CD = 4

Step-by-step explanation:

I believe you know the geometric mean for altitudes?

CD = √AD * DB = √8 * 2 = √16 = 4

If you are not aware of this theorem, then use the similarity of triangles.

ADC ~ CDB

AD/DC = CD/DB (cross-multiply)

CD^2 = AD*DB,

CD = √AD * DB = √8 * 2 = √16 = 4

Answer:

B. s = 24t

Step-by-step explanation:

Since s varies directly with t, therefore, equation that will represent the relationship would take the form of s = my

m = rate of change

✔️Find the rate of change:

Rate of change using two given pairs, (0.5, 12) and (2.5, 60),

Rate of change (m) = ∆s/∆t = (60 - 12)/(2.5 - 0.5) = 48/2 = 24

✔️Substitute m = 24 into s = mt

s = 24t

Step-by-step explanation:

Answer:

b. V = 336 ft³

Step-by-step explanation:

[tex]V = \frac{1}{2}bhl\\b = 14\\h = 8\\l = 6\\V = \frac{1}{2}(14)(8)(6)\\V = 336 ft^{3}[/tex]

Given:

A rectangular piece of land has an area of [tex]\dfrac{3}{4}[/tex] square mile.

The land is [tex]2\dfrac{1}{2}[/tex] miles long.

To find:

The width of the rectangular land.

Solution:

We have,

Area of a rectangle =  [tex]\dfrac{3}{4}[/tex] square mile.

Length = [tex]2\dfrac{1}{2}[/tex] miles

We know that, area of a rectangle is

[tex]A=l\times b[/tex]

[tex]\dfrac{3}{4}=2\dfrac{1}{2}\times b[/tex]

[tex]\dfrac{3}{4}=\dfrac{2(2)+1}{2}b[/tex]

[tex]\dfrac{3}{4}=\dfrac{5}{2}b[/tex]

Multiply both sides by [tex]\dfrac{2}{5}[/tex], we get

[tex]\dfrac{2}{5}\times \dfrac{3}{4}=\dfrac{2}{5}\times \dfrac{5}{2}b[/tex]

[tex]\dfrac{6}{20}=b[/tex]

[tex]\dfrac{3}{10}=b[/tex]

Therefore, the width of the land is [tex]\dfrac{3}{10}[/tex] miles.

Answer:

1.6 Hz

Step-by-step explanation:

I know this was posted a week ago, but, if you still need help:

You can set up a proportion, as follows.

50 / 2  =  40 / x => where x = frequency in Hz,

x = 2*40/50 = 80/50 = 8/5 = 1.6 Hz

Simple Question.

Answer: answer is d

Step-by-step explanation:

i would explain but im helping 7 other people rn

Answer:

Here you can use any!

sin x = 64/80

cos x = 48/80

tan x = 64/48

7 + x/4 = 15

x/4 = 15 - 7

x/4 = 8

x = 8 · 4

x = 32

Answer: x=32

Step-by-step explanation:

Given

7+x/4=15

Subtract 7 on both sides

7+x/4-7=15-7

x/4=8

Multiply 4 on both sides

x/4 ×4=8×4

x=32

Answer:

a = 9

b = 6

I hope you can do the rest yoyrself, as I coulsnt find how to type it out ;-;

Answer:

1) 117

2) 9

3) 45 or -45

Step-by-step explanation:

a=9

b=6

1) a²+b²=9²+6²=81+36=117

2) (a-b)²=(9-6)²=3²=9

3) a²-b²=81-36=45

It’s also possible that a=6 and b=9, in which case

1) (same)

2) (same)

3) 36-81=-45

Step-by-step explanation:

1) Expand by distributing terms.

[tex]5 + 6x - 8 - x[/tex]

2) Collect like terms.

[tex](5 - 8) + (6x - x)[/tex]

3) Simplify.

[tex] - 3 + 5x[/tex]

4) Regroup terms.

[tex]5x - 3[/tex]

Therefor the answer for this equation will be, 5x - 3.

Answer:

5x-3

Step-by-step explanation:

distribute 2 to 3x and -4

then you get 5+6x-8-x

combine like terms

5-8; 6x-x

you get: 5x-3

Given:

Consider the function is

[tex]f(x)=\dfrac{3x+2}{x}[/tex]

To find:

The inverse of the function, .i.e., [tex]f^{-1}(x)[/tex].

Solution:

We have,

[tex]f(x)=\dfrac{3x+2}{x}[/tex]

Putting f(x)=y, we get

[tex]x=\dfrac{3y+2}{y}[/tex]

Isolate the variable y.

[tex]xy=3y+2[/tex]

[tex]xy-3y=2[/tex]

[tex]y(x-3)=2[/tex]

[tex]y=\dfrac{2}{x-3}[/tex]

Putting [tex]y=f^{-1}(x)[/tex], we get

[tex]f^{-1}(x)=\dfrac{2}{x-3}[/tex]

Therefore, the inverse function is [tex]f^{-1}(x)=\dfrac{2}{x-3}[/tex].

Answer:

no it does not belong to the graph

Step-by-step explanation:

plug in the x-coordinate and see if it gives you the y-coordinate (1). if 1 is what comes out, then it is not a point on the graph.

y = -2(1/2)

y = -1

y = -1  when x = 1/2, which is not 1 so it does not belong to the graph
