Answer: distance from 15.3 to zero on a number line

Step-by-step explanation:

340=10f.

frequency=34hertz.

Step-by-step explanation:

We have the wavelength which is 10,speed/velocity=340 and frequency=?.

The formula is velocity=frequency × wavelength.

340=f × 10.

340=10f.

frequency=34hertz.

Answer:

[tex]\mathrm{A.\: 39.3}[/tex]

Step-by-step explanation:

Let [tex]h[/tex] represent the height of the two smaller triangles in this figure. Because all three triangles are similar, we can set up the following proportion:

[tex]\frac{33}{h}=\frac{h}{y}[/tex], for [tex]y=x-33[/tex].

We can solve for [tex]h[/tex] using the Pythagorean theorem on the second largest triangle:

[tex]33^2+h^2=36^2,\\h=\sqrt{36^2-33^2},\\h=\sqrt{207}[/tex].

Now plugging in [tex]h=\sqrt{207}[/tex] into our proportion [tex]\frac{33}{h}=\frac{h}{y}[/tex], we can solve for y:[tex]\frac{33}{\sqrt{207}}=\frac{\sqrt{207}}{y}[/tex].

Cross-multiply to get:

[tex]33y=207,\\y=\frac{207}{33},\\y\approx 6.3[/tex].

Since we [tex]y=x-33, y+33=x[/tex].

Therefore, our answer is:

[tex]x=33+y=33+6.3=\fbox{$\mathrm{A.\: 39.3}$}[/tex].

Answer:

(-3, 5) satisfies both the equation 6x + 5y = 7 and the equation x + 4y = 17.

Step-by-step explanation:

Answer:

D (-3, 5) satisfies both the equation 6x + 5y = 7 and the equation x + 4y = 17.

Answer:

The two expressions A and B are equivalent because the value of both expressions is same.

Step-by-step explanation:

Given: Expression A is 5(4+9) and expression B is 29+36.

To find: The reason why expressions A and B are equivalent.

First we solve expression A.

[tex]5(4+9)=5*4+5*9[/tex]          (using [tex]a(b+c)=a*b+a*c[/tex])

⇒[tex]5(4+9)=20+45[/tex]

⇒[tex]5(4+9)=65[/tex]

Now we solve expression B.

[tex]29+36=45[/tex]

Clearly, the value of both the expressions is same.

Hence, the expression A is equivalent to expression B.

Answer:

84 years

Step-by-step explanation:

Given :

At present :

Let :

daughter's age = x

Woman's age = 2x

21 years ago :

Woman's age = 3 times daughter's age

2x - 21 = 3(x - 21)

2x - 21 = 3x - 63

-21 + 63 = 3x - 2x

42 = x

Daughter's age = 42

Woman's age = 2x = 84

Hence, woman's present age is 42 years

Answer:

Please check explanations

Step-by-step explanation:

When we talk about the slope, we are simply referring to the change in y-value with respect to a change in x-value

From the regression line equation, we can see that the value of the slope is negative

What this means is that as the x value is increasing, the y value is decreasing

This makes sense in the context of the problem because it is expected that the amount of fuel in liters is expected to decrease with an increasing amount of time

Answer:

Step-by-step explanation:

Remark

We have to assume that the die is a cube.

We know that getting a 3, if the die is fair,  is 1 chance out of 6 = 1/6

We don't know how many blues there are on the spinner, but we do know that the number of them is over 20. So that's x/20

Now multiply the left side to get the combined probability. x/20 * 1/6. The result is 10.83/ 100

Solution

(x/20) * (1/6) = 10.83/100

x / 120 = 10.83/100                     Multiply both sides by 120

x = 10.83 * 120 / 100

x = 12.996 which is going to round to 13

The blue spaces = 13

Answer:

i beleve they would get an 80% sorry if im wrong

Answer:

the answer is 80%

Step-by-step explanation:

Think of it this way

There is 5 problems wrong out of 25 so    5/25  is the fraction   (right/ number of questions)    

5/25 can be simplified to 1/5     (divide by 5)

1/5  can be transformed to the percentage 20%

NOW BE CAREFUL  20% is what is WRONG so 100-20=80

so 80% is thus the answer

Answer:

176cm

Step-by-step explanation:

Step 1

We find the circumference of the cylinder

The formula for the Circumference = 2πr or πD

π = 22/7

Hence;

22/7 × 7

= 22

Since the strip of paper eight times round a cylindrical pencil of diameter 7mm, the length of the paper is calculated as: 22 × 8

= 176cm

Answer:

1)x=-6,y=1 2)a=0,b=-8 3)j=8,k=1 4)m=3,n=-6

Step-by-step explanation:

1)x-4y=-10,2x+y=-11

x-4y=-10

x=4y-10

2\left(4y-10\right)+y=-11

8y-20+y=-11

9y-20=-11

9y=9

y=1

x=4-10

x=-6

x=-6,y=1

2)a-3b=24,a+2b=-16

a-3b=24

a=3b+24

3b+24+2b=-16

5b+24=-16

5b=-40

b=-8

a=3\left(-8\right)+24

a=-24+24

a=0

a=0,b=-8

3)k-j=-7

4j-5k=27,-j+k=-7

4j-5k=27

4j=5k+27

j=\frac{1}{4}\left(5k+27\right)

j=\frac{5}{4}k+\frac{27}{4}

-\left(\frac{5}{4}k+\frac{27}{4}\right)+k=-7

-\frac{1}{4}k-\frac{27}{4}=-7

-\frac{1}{4}k=-\frac{1}{4}

k=1

j=\frac{5+27}{4}

j=8

j=8,k=1

4)m+n=-3,m-4n=27

m+n=-3

m=-n-3

-n-3-4n=27

-5n=30

n=-6

m=-\left(-6\right)-3

m=6-3

m=3

m=3,n=-6

55 pirates

121 pirates

Step-by-step explanation:

Every 11 pirates for one pirate ship.

5 * 11 = 55

Therefore, it would be 55 pirates

11 * 11 = 121

Therefore, it would be 121 pirates
