Answer:

1000000

Step-by-step explanation:

I'm not sure what you meant by "scientific notation". So uhh, I only solved the 1.0 times 10^6,

10^6=10×10×10×10×10×10

10^6=1000000

(Fun fact. If you ever see a power of 10, you don't actually need to solve it. Look at the power, and add the same amount of 0's. For example 10^2. Power sign is 2. 2 trailing 0's.)

Step-by-step explanation:

if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)

if leg b is unknown, then. b = √(c² - a²)

for hypotenuse c missing, the formula is. c = √(a² + b²)

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

scale factor = [tex]\frac{PQ}{XY}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

That is the sides of Δ PQR are half those of Δ XYZ, thus

The perimeter of Δ PQR is half Δ XYZ, that is

perimeter of Δ PQR = [tex]\frac{1}{2}[/tex] × 20 = 10

Answer:

Amount Noah spent on cappuccino for that week = $22.95

Step-by-step explanation:

Noah pays $7.65 for a cappuccino on days he's running late to work

Cost of cappuccino per day = $7.65

One week, he was late on Monday, Wednesday, and Friday.

That is 3 days in a week

How much did he spend (in $) on cappuccinos that week? $

Amount Noah spent on cappuccino = cost of cappuccino per day × 3 days

= $7.65 × 3

= $22.95

Amount spent on cappuccino for that week = $22.95

Answer:

x= 15/2 im pretty sure

Step-by-step explanation:

We want to solve the given linear equation, we will find that the solution is x = -3.7

Here we have the equation:

3.8 = 2*x - 11.2

We want to solve this for x, so we can start by subtracting 11.2 in both sides to get:

3.8 - 11.2 = 2*x

-7.4 = 2*x

Now we can divide both sides by 2:

-7.4/2 = x = -3.7

So the solution is x = -3.7

The value of x in the equation (m^5/6) (m^1/6)^7 = m^x is 2

The exponents of numbers are added when the numbers are multiplied, subtracted when the numbers are divided, and multiplied when raised by still another exponent: a^m×a^n = a^(m+n); a^m÷a^n = a^(m−n);

(am)ⁿ = a^mn.

Given an equation, (m^5/6) (m^1/6)^7 = m^x

Using the law of exponent, we get,

(m^5/6) (m^1/6)^7 = m^5/6*m^7/6

= m^(5/6+7/6)

= m^12/6

= m^2

Hence, the value of x in the equation (m^5/6) (m^1/6)^7 = m^x is 2

Step-by-step explanation:

Given the ratio of blueberries to strawberries in a fruit salad to be 4:3. The total ratio = 4+3 = 7

If there are 45 strawberries in the salad then we can first calculate the total mixture of both as shown;

amount of strawberries = 3/7 * x = 45

x is the total amount of mixture

from the expression;

3x/7 = 45

cross multiply

3x = 7*45

3x = 315

x = 315/3

x = 105

The amount of blueberries present = 105 - 45 = 60

Hence the amount of blueberries present is 60 blueberries

Answer:

The equation of line n is;

y = -3x - 23

Step-by-step explanation:

Here, we want to find the equation of line n

For the alternate interior angles to be congruent after drawing the transversal, then both lines must be parallel

If the two lines are parallel, then their slopes are equal

To get the slope of line m, we compare the equation of line m to the standard form

The equation of line m is y = -3x + 8

if we compare this with the standard form which is y = mx + c

Then the slope of line m is -3 and since they are parallel lines, the slope of line n is -3 too

So now, we need to get the equation of line n

It passes through (-4,-11)

What we have already is;

y = -3x + c

we need to get the y-intercept to write the complete equation

To get the y-intercept we simply substitute for (-4,-11)

Thus, we have

-11 = -3(-4) + c

-11 = 12 + c

c = -11-12 = -23

The equation of line n is;

y = -3x - 23
