Step-by-step explanation:

Answer: the answer is 64.

Step-by-step explanation: I just did the practice.

Answer:

Step-by-step explanation:

So first we distribute -12 to 6 making that -72 then we distribute the -12 to the 4 making that -48.

So we have -72+-48 = -72 - 48 = -120

It is important to know that the answer is not -120 (10)(-12) = -120

because that is not the distributive property.

Answer:

[tex]VW = 50[/tex]

Step-by-step explanation:

Given

The attached triangle

Required

Find VW

To find VW, we make use of the following equivalent ratios.

[tex]YX : XW = ZX : XV[/tex]

Where:

[tex]YX = ZX - ZY = 42 - 28 = 14[/tex]

[tex]XV = XW + VW = 25 + VW[/tex]

So, we have:

[tex]14 : 25 = 42 : 25 + VW[/tex]

Express as fraction

[tex]\frac{14 }{ 25 }= \frac{42 }{ 25 + VW}[/tex]

Divide both sides by 14

[tex]\frac{1}{ 25 }= \frac{3}{ 25 + VW}[/tex]

Cross multiply

[tex](25 + VW) * 1 = 3 * 25[/tex]

[tex]25 + VW = 75[/tex]

Solve for VW

[tex]VW = 75 -25[/tex]

[tex]VW = 50[/tex]

The null hypothesis is : [tex]$u_1=u_2=u_3=u_4$[/tex]

Alternative hypothesis : At least one of the [tex]$u$[/tex] is not equal.

The significance level = 0.05

Analyzing the sample data:

F statistics is given by :

[tex]$F=\frac{MSB}{MSE}$[/tex]

  = 2.97

[tex]$F_{critical}=3.24$[/tex]

The P-value= 0.06

The result : Since the P-value of 0.06 is greater than the significance level (0.05), hence we fail to reject the null hypothesis.

So we cannot conclude that there is no difference between the average maximum heart rates that are achieved during the four workouts.

Answer:

each tangent is 20.785 ft long

Step-by-step explanation:

since the tangent forms a right angle with the radius, and a line from P to O bisects the 60° angle:

tan 30° = 12/x

0.5774 = 12/x

0.5774x = 12

x = 20.785 ft

Answer:

  32 dm

Step-by-step explanation:

Use the formula for the area of a triangle, and solve for the unknown.

  A = 1/2bh

  200 dm² = 1/2(12.5 dm)b

  b = (200 dm²)/(6.25 dm) = 32 dm

The base of the triangle is 32 dm.

Answer:

assuming that you want us to add them together here's the answer i got-

5y²−3y+3

Step-by-step explanation:

let us simplify step-by-step-

4y²−2y−5+y²(−y)+8

= 4y²+(−2y)+(−5)+y²+(−y)+8

combining like terms-

=4y²+−2y+−5+-y²+−y+8

=(4y²+y²)+(−2y+−y)+(−5+8)

=5y²+−3y+3

good luck :)

Answer:

The first blank is 9  for 9 cucumbers

The second blank is 8 dollars

Step-by-step explanation:

We can use ratios to solve

3 cucumbers           x cucumbers

--------------------- = ----------------------

2 dollars                   6 dollars

Using cross products

3*6 = 2x

18 = 2x

Divide by 2

18/2 = 2x/2

9 =x

We need 9 cucumbers

For the third row

3 cucumbers           12 cucumbers

--------------------- = ----------------------

2 dollars                   y dollars

Using cross products

3*y = 2*12

3y = 24

Divide by 3

3y/3 = 24/3

y = 8

We need 8 dollars

Answer:

I only know the first question, If you leave that money for 1 year it would equal $480 basically,  $300 x 1.6 = $480.

Step-by-step explanation:

The required amount in your account after 2 years will be $337.08.

Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.

Here,
If you deposit $300 in an account with a 6% interest rate, the amount in your account after 1 year can be calculated as follows:

Find the interest earned after one year:

Interest earned = (6/100) x 300 = $18

Add the interest earned to the original amount:

Total amount after 1 year = $300 + $18 = $318

Therefore, the amount in your account after 1 year will be $318.

If you leave this money in the account for another year, the amount in your account after 2 years can be calculated as follows:

Find the interest earned after two years:

Interest earned in year 1 = $18

Interest earned in year 2 = (6/100) x $318 = $19.08

Add the interest earned to the original amount and the interest earned in year 1:

Total amount after 2 years = $300 + $18 + $19.08 = $337.08

Therefore, the amount in your account after 2 years will be $337.08.

The value of x in the stated triangle is 6.32 based on given dimensions.

The stated triangle is right angled triangle and hence will follow Pythagoras theorem. The calculation will be done using the Pythagoras formula as stated -

Perpendicular² = Base² + Height²

Keep the values in formula to find the value of x

x² = 2² + 6²

Taking square on the Right Hand Side of the equation

x² = 4 + 36

Add the digits on Right Hand Side of the equation

x² = 40

x = ✓40

Taking square root

x = 6.32

Hence, the length of x is 6.32.

Yes, they are proportional

Step-by-step explanation:

First, simplify each fraction

30/80 can be simplified by dividing each number by 10

30/80

= 3/8

24/64 can be simplified by dividing each number by 8

= 3/8

So, each fraction will simplify to 3/8, meaning that they are proportional.

Answer:

10c - 5

Step-by-step explanation:

" the product" tells you you're multiplying 10 and c, and "5 less" means subtracting 5 from the other part of the expression.

Answer: y = x^2 + 6x+ 9 = 0. (X+3)^2= 0 when x=3. This has one root.

X^2-2x -24 = 0 a= 1 b=-1 and c= -24 x = {-(-1) +/- sqrt((-1)^2 -4 x 1 x (-24)}/2
