Kelly has some money saved. After mowing two lawns on Saturday, she adds $40 to her savings. Write an expression to represent how much money has Kelly saved.

(will give brainlist.. if you put soething random then im reporting you and will email brianly and give them your user)

Answers

Answer:

x+40 or 40+x

Step-by-step explanation:

It doesn't tell you the amount of money she's saved before so you make it a variable. I used x.

After mowing she got $40 and decided to add that to her savings.

You already know her savings before, x, and now you have $40.

So you end up writing the expression x+40 or 40+x.

Let’s say that the amount of money saved is the variable ‘x’.

There is a key word in the second sentence to be aware of. It’s simply the word, ‘add’, and when that word is there, we just simply do addition.

Remember that x is always first in an expression, though if it looks weird, you can just switch it; it’s alright.


Key word: Add = addition

Expression: 40 + x

Rashida is building a model of her city's downtown area. She is constructing part of an office building, as shown below. Each cube has a length of centimeter.





Based on the model, the length of the building is
centimeter.

The width of the model building is
centimeter.

The height of the model building is
centimeter.

The volume of the model building is
cubic centimeter.

Answers

6-7 that’s ur awnser girl

Based on the model, we find the dimensions of the cube. The length of the model building is 2/3 centimeter. The width of the model building is 1/3 centimeter. The height of the model building is 1/2 centimeter. The volume of the model building is 1/9 cubic centimeter.

What are dimensions of a cube?

A cube is 3- dimensional shape with 6 equal sides, 6 faces, and 6 vertices in geometry. Each face of a cube is a square. In 3 – dimension, the cube’s sides are; the length, width, and height. Sides of a cube are all equal i.e. Length = Width = Height = a.

The length = breadth = height (of one cube) = 1/6 cm

The length of the model consist of 4 cubes.

Length of model building = 4 * 1/6 cm = 2/3 cm

The width of the model consist of 2 cubes.

Width of model building = 2 * 1/6 cm = 1/3 cm

The height of the model consist of 3 cubes.

Height of model building = 3 * 1/6 cm = 1/2 cm

Volume of the model (cuboid) =

= Length * breadth * height

= [tex]\frac{2}{3} * \frac{1}{3}*\frac{1}{2} = \frac{1}{9}[/tex]

Julie says the most amount of time spent homework is 1 1/2 times the least amount of time spent on homework. Is she correct? Explain.
Daniel says that more than half the students spent 2 1/2 hours or more on homework. Liz says more than half the students spent less 2 1/2 hours on homework. Who is correct? Explain.

Answers

From the values in the statistical data we have;

The most amount of time spent is [tex]3\frac{3}{4}[/tex] the least amount of time, Julie is incorrectLiz is correct because 7 out of 12 students spend less than [tex]2\frac{1}{2}[/tex] on homework

How can the given statements be evaluated?

The possible given data in question, are as follows;

[tex]\begin{array}{cccc}1\frac{3}{4} &2\frac{1}{2} &2&2\frac{3}{4} \\\\1&1\frac{3}{4} &1\frac{1}{4} &3\\\\3\frac{1}{4} &3\frac{3}{4} &2&2\end{array}\right][/tex]

From the data, we have;

The most amount of time spent = [tex]3\frac{3}{4}[/tex]

The least amount of time spent = 1

Therefore;

The most amount of time is [tex]3\frac{3}{4} \times 1[/tex] = [tex]3\frac{3}{4}[/tex] times the least amount of time

Julie is incorrect

Second part;

The number of students that spent less than [tex]2\frac{1}{2}[/tex] = 7

The number of students that spent [tex]2\frac{1}{2}[/tex] or more = 5

The number of students in the survey = 12

Therefore, more than half the students spent less than [tex]\mathbf{2\frac{1}{2}}[/tex] hours on homework

Answers

Answer:

Step-by-step explanation:

The above list is for the figures numbered 1-3 (left to right) on the top row, and 4-5 (left to right) on the bottom row.

__

"Alternate" angles are on opposite sides of the transversal. If the angles are between the parallel lines, they are "interior" (fig 4). If they are outside the parallel lines, they are "exterior" (fig 1).

"Corresponding" angles are found in the same direction from the point of intersection. Upper-left corresponding angles are seen in fig. 3; lower-right corresponding angles are seen in fig. 5.

The angles marked in figure 2 are "consecutive exterior" angles, also called "same-side exterior" angles. The applicable descriptive choice in this problem is "none of these".
