Answer: 919,80

Step-by-step explanation:

Answer:

920,000

Step-by-step explanation:

9   hundred thousands

1    ten thousands

9   thousands

8   hundreds

2   tens

7   ones

Rounding: 5 and up round up, 4 and below round down.

8 is higher than 4 so you round 919,827 to 920,000.

Answer:

the answer is the third one k > - 5

Answer/Step-by-step explanation:

 Step 1: Simplify both sides of the inequality.

[tex]\frac{1}{4}k+\frac{-3}{4}>-2[/tex]

Step 2: Add 3/4 to both sides.

[tex]\frac{1}{4}k+\frac{-3}{4}+\frac{3}{4}>-2+\frac{3}{4}[/tex]

[tex]\frac{1}{4}k>\frac{-5}{4}[/tex]

Step 3: Multiply both sides by 4.

[tex]4*\frac{1}{4}k>4*\frac{-5}{4}[/tex]

K > -5

 So according to this the value of k has to be greater than -5

You can check your answer by substituting the values in for k.

You can use a calculator..

[tex]\frac{-10-3}{4} >-2[/tex]  

[tex]\frac{-7-3}{4} >-2[/tex]

[tex]\frac{-1-3}{4} >-2[/tex]

[tex]\frac{0-3}{4} >-2[/tex]

Solve these and you will get your 2nd answer.

Answer:

Whichever line has a slope of -2

Step-by-step explanation:

rewrite in slope intercept

y=mx+b     where m=slope

y=-2x+7

-2 is the slope of the original line

a parallel line will never intersect

the parallel line must have the same slope

Answer:

120

Step-by-step explanation:

As those two lines are parallel, we can express and equation:

[tex](6x + 18) + (4x - 8) = 180[/tex]

[tex]6x + 4x = 180 - 18 + 8[/tex]

[tex]10x = 170[/tex]

[tex]x = 17[/tex]

[tex]6x + 18 = 102 + 18 = 120[/tex]

Answer: Take your pick, Emily.

Step-by-step explanation:

1) Assuming Emily wants both Chocolate Chip(CC) and Sugar Cookies(SC) in each basket, she could make 20 baskets having 1 CC and 2 SC in each basket. That would leave 8 SC (48-40) without any matching CC.

2) If Emily doesn't care about the makeup of each basket (e.g., some baskets may have any combination of cookies), she has a total of (20 + 48) or 68 cookies. She has the following choices:

1 cookie each: 68 baskets

2 cookies each: 34 baskets

3 cookies each: 22 baskets with 2 cookies left over

And so forth.

Unless Emily was given some other condition (e.g., a minimum of 5 cookies/basket), there are many possible answers.

Answer:

7 would be the constant

Step-by-step explanation:

Constants are the values in an equation that never changed or are isolated. For instance, 5 would not be a constant because of the variable (x) being multiplied. Though, if it were 5+x square +7, 5 and 7 would be the constants.

Answer:

what to do now

Step-by-step explanation:

Answer: a. x = 15, y = 40

Step-by-step explanation:

So we already know that ΔABC and ΔFDE are congruent, which means their angles are equal. Based on this information, we could note that:

∠A = ∠F

∠C = ∠E

∠B = ∠D

Since we already know the measurement of ∠B, we could then conclude that ∠D, or y, is equal to 40°. This leaves us with two possible answers, a or b.

In order to find the value of x, we need to know the measurement of ∠F. And in order to find ∠F, we need to find the measurement of ∠A. We already know that the angles in a triangle sums up to 180°. So we would start as the following.

∠A + ∠B + ∠C = 180

We first substitute the known measurements.

∠A + 40 + 110 = 180

We then add up 40 with 110.

∠A + 150 = 180

We finally substract 150 on both sides of the equation. This gives us the measurement of ∠A.

∠A = 30°

Now that we know ∠A, we could start finding the value of x. So we already know this:

∠A = ∠F

We first substitute each angle with their known measurements.

30 = 2x

We now divide both sides by two. This gives the value of x.

x = 15

Answer:

66.6% decrease in distance

Rounded 67%

He is traveling 1/3 of what he used to travel

Step-by-step explanation:

The percentage of decrease in the distance Theo travels to work is 66.7%.

Used concept of percentage;

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating the hundredth part of any quantity is called a percentage.

Given that;

Theo used to drive 60 miles to work each day.

And, His new home is now 20 miles away from his job.

Hence the percentage of decrease in the distance Theo travels to work is,

P = (60 - 20)/60 x 100

P = 40/60 x 100

P = 66.7%

So, The percentage of decrease in the distance Theo travels to work is 66.7%.
