Larry's statement is correct

Step-by-step explanation:

Larry says 5 × 900 is less than 5 × 9,000.

Doni says 5 × 900 is greater than 5 × 9,000.

5 × 900 = 4500

5 × 9000 = 45,000

45,000 is greater than 4500 because the place value of 45,000 is tens thousands and 4500 is Thousands.

Hence, Larry's statement is correct.(Larry says 5 × 900 is less than 5 × 9,000.)

Answer:

is this triangle supposed to be a right triangle?

Step-by-step explanation:

i can't solve unless i know the type of triangle

Answer:

B. 13

First, use the Pythagorean Theorem

a^2 + b^2 = c^2

5^2 + 12^2 = c^2

25+144=c^2

169=c^2

square root of 169=13

Therefore your answer would be, B. 13

WE know, compound interest is given by :

[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]

Here, P is principle amount.

r is annual interest rate.

n, number of times that interest is compounded per unit t .

t, time the money is invested or borrowed for.

To Find :

How much more money would Isabella have in her account than Gabriel, to the nearest dollar.

Solution :

[tex]D = P(1 + \frac{r_1}{n})^{nt}- P(1 + \frac{r_2}{n})^{nt}\\\\D = 77000\times ( 1 + \dfrac{33}{8\times 12})^{12\times 6}-77000\times ( 1 + \dfrac{7}{2\times 12})^{12\times 6}\\\\D = \$(1.257\times 10^{14})[/tex]

Hence, this is the required solution.

Answer: 3534

3534 in delta math

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

Let x be the number of cell phones with keyboards needed.

40% = [tex]\frac{40}{100}[/tex]

[tex]\frac{x+45}{x+120}[/tex] = [tex]\frac{40}{100}[/tex]

x+45 = 40 -----1

x+120 = 100 -----2

You would want to make the total of 1 the same as 2.

1×[tex]\frac{100}{40}[/tex]: 2.5+112.5 = 100 -----3

Now 2 and 3 are equal.

x+120 = 2.5x+112.5

Isolate the x and numbers.

120-112.5 = 2.5x-x

Simplify.

1.5x = 7.5

x = [tex]\frac{1}{1.5}[/tex] × 7.5

x = 5

The manager of the store needs to add 5 more cell phones with keyboards.

Answer:

sq rt of 32 units

Step-by-step explanation:

use the pythagorean theorem:

4^2 + 4^2 = c^2

16 + 16 = c^2

32 = c^2

sq rt of 32 = c

The length of the hypotenuse of a right triangle is 4√2.

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

Given:

P= 4 units, B= 4 units

Now, using Pythagoras theorem

H² = P² + B²

H² = 4² + 4²

H²= 16+ 16

H² =32

H= √32

H= 4√2

Hence, the Hypotenuse is 4√2.

j=3+25, here's the equation

Step-by-step explanation:

J=28

Answer:

j = 28

Step-by-step explanation:

Since we know that j is 25 more than 3, then we must know that 3+25= J (because J is 25 more/+ than 3) So, we simply solve 25+3 which equals 28.

Answer:

[tex]6\frac{2}{3}[/tex] %

Step-by-step explanation:

First, convert 3 meters into centimeters.

1m = 100cm

3m = 100 × 3 = 300cm

Now, form the fraction by putting the given value, 20cm, over the total measurement, 300cm.

[tex]\frac{20}{300}[/tex] = [tex]\frac{2}{30}[/tex] = [tex]\frac{1}{15}[/tex]  ⇒ Simplify your fraction to its simplest terms.

Next, multiply your simplified fraction by 100 to get your percentage.

[tex]\frac{1}{15}[/tex] × [tex]100[/tex] = [tex]\frac{100}{15}[/tex] = [tex]6\frac{10}{15}[/tex] = [tex]6\frac{2}{3}[/tex] %   ⇒ Simplify your percentage to its simplest terms.

20cm as a percentage of 3m as a mixed fraction is 6  2/3 %

let's convert centimetre to metre

1 cm = 0.01 m

20 cm = ?

cross multiply

length in metre = 20 × 0.01 = 0.2 m

Therefore,

0.2 m as a percentage of 3m is as follows:

0.2 / 3 × 100 = 20 / 3 = 6  2 / 3 %

Step-by-step explanation:

4(2x - 1) = 3x + 6

Simplify

8x - 4 = 3x + 6

Subtract 3x from both sides

8x - 3x - 4 = 3x - 3x + 6

5x - 4 = 6

Add 4 to both sides

5x - 4 + 4 = 6 + 4

5x = 10

Divide both sides by 5

5x/5 = 10/5

x = 2

Step-by-step explanation:

4(2x - 1) = 3x + 6

8x-4=3x+6

8x-3x=6+4

Given :

The store sells gasoline for .25 per gallon below it's regular cost per gallon.

Suppose the store sells 5,750 gallons that day.

To Find :

the stores profit or loss in comparison to the amount the store would had made without the special offer.

Solution :

Since, store is selling gasoline for lower amount than regular so they will be in loss.

Loss =$ 0.25 × 5750

Loss = $1437.5

Therefore, loss of store in comparison to the amount the store would had made without the special offer is $1437.5 .

Hence, this is the required solution.

The new point after rotation of point  (-7, -3) counterclockwise by 90 degrees will be ( 3, -7).

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.

For example (5,3) here 5 will be for the x and 3 will be for the y.

Another example is (9,0) here 9 is for x and 0 is for y.

Given,

Point A =  (-7, -3)

Let's say after rotation this point moves to a new coordinate (x, y) which is point B

Let's say the origin is O

Slope of line segment AO = (-3-0)/(-7-0) = 3/7

Slope of line segment BO = (y - 0)/(x - 0) = y/x

Now,

Since both lines are perpendicular to each other so

Slope AO × Slope BO = -1

3/7 × y/x = -1 ⇒ 3y = -7x

Now if we observe the result then it will be clear that if we put x = 3 than y = -7 will be the new coordinate.

Hence, The new point after rotation of point  (-7, -3) counterclockwise by 90 degrees will be ( 3, -7).
