Is the answer to this question 84?

Answers

Answer 1

Answer:

Answer:

yes ∠ A = 84°

Step-by-step explanation:

∠ A and ∠ B are same side interior angles and supplementary, thus

5x + 34 + 2x + 76 = 180

7x + 110 = 180 ( subtract 110 from both sides )

7x = 70 ( divide both sides by 7 )

x = 10

Thus

∠ A = 5x + 34 = 5(10) + 34 = 50 + 34 = 84°

Nine tenths of a sum of money is 45. Find the whole amount

Answers

If you would like to know the whole amount of money, you can calculate this using the following steps:

nine tenths of a sum of money is 45
9/10 * x = 45 /*10
9 * x = 45 * 10 /9
x = 45 * 10 / 9
x = 50

Result: Nine tenths of 50 is 45.

The answer is 50.

First do 45 divided by 9 which is 5 then times by 10 results in 50.

A way to check this is by then finding 1/10 of 50 which is 5 then X by 9 is 45, which is what you originally started with.

PLEASE HELP MEDavid and Ronald both are making cubic gift boxes with varying volume. The side length of David's gift box for a given volume is given by the function below, where (x - 1) is the volume of the box, in cubic feet.

The side length, g(x), of Ronald's gift box for a given volume is shown in the table below, where x is the volume of the box, in cubic feet.

Whose gift box has the greater side length for a given volume?

Answers

Answer:

Option C Both gift boxes have the same length for a given volume

Step-by-step explanation:

step 1

David's gift box

Calculate the side length of the box for a given volume

we have

$f(x)=\sqrt[3]{x-1}$

For $(x-1)=2\ ft^(3)$ ------> $f(x)=\sqrt[3]{2}=1.26\ ft$

For $(x-1)=4\ ft^(3)$ ------> $f(x)=\sqrt[3]{4}=1.59\ ft$

For $(x-1)=6\ ft^(3)$ ------> $f(x)=\sqrt[3]{6}=1.82\ ft$

For $(x-1)=10\ ft^(3)$ ------> $f(x)=\sqrt[3]{10}=2.15\ ft$

therefore

Both gift boxes have the same length for a given volume

Answer:

It would take five hours for all the bacteria to die. 1000 divided by 5 is 200 so 200×5 = 1000

Last weekend 1270 students participated in the music festival. Write 1270 in expanded form using exponents

Answers

The exponent form of students participating in the music festival is

1×10³ + 2×10² + 7×10¹.

What is the standard decimal form of numbers?

The standard decimal form of numbers is written in base 10 as there are 10 different numbers from 0 to 9.

Each digit has a face value and a place value.

Given, Last weekend 1270 students participated in the music festival.

Now, 1270 in exponent form is as follows,

1270 = 1000 + 200 + 70.

1270 = 1×1000 + 2×100 + 7×`0.

1270 = 1×10³ + 2×10² + 7×10¹.
