A window washer cleaned 38 windows in 2 hours. At this rate, how many windows did he clean in 7 hours?

Answers

38:2=
19:1=
133:7
133 windows.

To solve this problem, we need to find the unit rate (the amount of windows cleaned per hour) and multiply by 7.

To find the unit rate, we need to divide 38 by 2:

38 / 2 = 19

Now, we need to multiply this by 7:

19 * 7 = 133

In 7 hours, the window washer can clean 133 windows.

You walk 2 miles in 1/
2 hour. At that rate, how long will it take you to walk 3 miles?

Answers

Hello!

1/2 = 0.5 as a decimal

0.5 ÷ 2 = 0.25

That means you walk 1 mile in 0.25 of an hour. Multiply this by three:

0.25 × 3 = 0.75

Answer:

It will take you 0.75 (or 3/4) hour to walk 3 miles.

The answer is:  " [tex] \frac{3}{4} [/tex] mi. " ; or, write as: " 0.75 mi. " .
__________________________________________

Write a proportion.
__________________________________________

[tex] \frac{(2) mi}{(0.5) h } = \frac{(3) mi.}{(x)h} [/tex] ;

Solve for "x" , [ (in units of "h"; (hours) ] ;

Note: "Cross-multiply" ;

Note: Given (a/b) = (c/d) ;   → ad = ab ; (b ≠ 0 ; d≠ 0) ;

→ 2x = (0.5 * 3) ;

→ 2x = 1.5 ;

Divide each side of the equation by "2" ;
to isolate "x" on one side of the equation; & to solve for "x" ;

→ 2x / 2 = 1.5 / 2 ;

to get:

→ x = 1.5 / 2 = 15/20 = (15÷5) / (20÷5) = 3/4 ;

or: → x = 1.5 / 2 = 15/20 = (15*5) / (20*5) = 75/100 = 75 ÷ 100 = 0.75 .

Question: I need to know an INTEGER to represent the total deposits Broderick made and another integer to represent Broderick needs from his checking account to cover the checks?

Answers

Broderick made 6 deposits of 35.50 each. Then total deposits are: 6*$35.50= $213

He needs to write 4 checks for 310.75 each. Then total checks are: 4* $310.75- $1243

To cover the checks, Broderick will need to add: $1243- ($420 + $213)= $610

The angles ∠2 = 135°, ∠3 = 135°, ∠4 = 45°, ∠5 = 45°, and ∠6 = 135° (all are in degrees)

What is an angle?

Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

The angle ∠1 = 45° is given. And the diagram is shown.

Types of the angles are as follows;

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.Vertically opposite angle - When two lines intersect, then their opposite angles are equal.Alternate angle - If two lines are parallel then the third line will make z -angle and z-angles are equal angles with the parallel lines.

∠1 + ∠2 = 180° (Supplementary angle)

45° + ∠2 = 180°

∠2 = 135°

∠1 = ∠5 = 45° (Corresponding angle)

∠2 = ∠6 = 45° (Corresponding angle)

∠1 = ∠4 = 135° (Alternate angle)

∠2 = ∠3 = 135° (Alternate angle)

What is the solution set?

3.3x−11.6>18.1

Enter your answer in the box.
Please answer fast thanks!

Answers

The solution set is (9, ∞).

To solve the inequality 3.3x-11.6>18.1, we need to isolate the variable x.

First, we can add 11.6 to both sides of the inequality to get 3.3x>29.7.

Then, we can divide both sides by 3.3 to solve for x: x>9.

We can express the solution set using interval notation as (9, ∞).

Therefore, The solution set is (9, ∞).

The solution set for the inequality 3.3x - 11.6 > 18.1 is x > 9, meaning x is greater than 9.

To solve the inequality 3.3x - 11.6 > 18.1, you can follow these steps:

1. Add 11.6 to both sides to isolate the term with x:

3.3x - 11.6 + 11.6 > 18.1 + 11.6

3.3x > 29.7

2. Now, divide both sides by 3.3. Remember, when you divide by a positive number, the inequality sign remains the same:

[tex]\[ \frac{3.3x}{3.3} > \frac{29.7}{3.3} \][/tex]

[tex]\[ x > \frac{29.7}{3.3} \][/tex]

x > 9

So, the solution set for the inequality 3.3x - 11.6 > 18.1 is x > 9.

Which number is written in scientific notation?

Where,
a: is a number between 1 and 10

What is Fraction?

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.

Given:

The store is 7⁄8 of a mile away from your house.

Distance covered by Walking = 1/5

and, the rest is covered by Bus.

So, the distance covered by Bus

= 7/8- 1/5

= 35/ 40- 8/40

= 27/40

Hence, 27/40 miles covered by Bus.

A vendor pays a rock band 1/3 of the total profit from T-shirts and sweatshirts sold at every concert. The vendor paid the rock band $726 after the last concert. If the profit from T-shirts sales was $1,632, what was the profit from sweatshirt sales?

Answers

Well, we know that the rock band receives 1/3 of the profits from sales of sweaters and T-shirts, so in this case, $726 was 1/3 of the profit for that particular concert.
Using this information, we know that is we multiply 1/3 by 3 we get 1 whole, so we also multiply $726 by 3 to get the value of all the profits:
$726×3= $2178
So, if $2178 was the total value of the profits and T-shirt profits were worth $1632, then the value of sweatshirt profits was $2178-$1632= $546
Therefore, your answer is $546

Basically, we need to find the diagonal of the square. Once we have the diagonal, we need to find if it's more or less than 11 cm, which is diameter of the circle.
This is the formula we'll use:
a²+b²=c²
Since it's a square, a and b are the same.
7²+7²=c²
49+49=c²
98=c²
√98=c
c=9.8995
So, the diagonal is 9.8995
9.8995<11

So, since the diagonal of the square is 9.8995 cm, it is less than the circumference of the circle meaning that it will fit in to the circle without touch the circle's circumference.

4. Find the missing value to the nearest hundredth.
sin________=8/15

Answers

These are two questions and two answers:

Question 3.

Answer: fourth option 9√2

Explanation:

1) Since the original quilt is square, you know that the diagonal length is the hypotenuse of the two triangles formed and it satifies this formula, derived from the Pythagorean theorem:

(diagonal) ^2 = (hypotenuse)^2 = 2 * (side length)^2

2) Solve for the side length:

(side length)^2 = (diagonal)^2 / 2

=> side length = √ [ (diagonal)^2 / 2 ] = diagonal * (√2) / 2

3) Substitute the diagonal length value:

side length = 18 * (√2) / 2 = 9√2

Question 4

Answer: second option 32.23°

Explanation

1) Given sin(angle) = 8 /15

2) To find the angle you have to use the inverse function, arcsin

The amount of money that Charlie saves each week is directly proportional to the amount he earns. Last week Charlie saved $32 on his earnings of $512. At the same rate, how much will Charlie save this week on his earnings of $448?

Answers

if k is a constant of proportionality then we know from last week that
512= k ·32 so k=512/32=16;

This week
448= k · amount he saved
448=16· amount he saved
amount saved=448/16=28

Answer $28

Answer:

$28.

Step-by-step explanation:

Let y represent of saved money and x represent amount of earned money.

We have been given that the amount of money that Charlie saves each week is directly proportional to the amount he earns.

We know that two proportional quantities are in form [tex]y=kx[/tex], where, k is constant of proportionality.

Substitute given values and solve for k:

[tex]32=k*512[/tex]

[tex]\frac{32}{512}=\frac{k*512}{512}[/tex]

[tex]\frac{1}{16}=k[/tex]

To find amount of saved money, we will substitute [tex]k=\frac{1}{16}[/tex] and [tex]x=448[/tex] in our equation.

[tex]y=\frac{1}{16}\cdot 448[/tex]

[tex]y=28[/tex]

Therefore, Charlie saved $28 in the given week.
