Answer:

All figures in Group 1 appear to have at

least one square face

Step-by-step explanation:

Let us examine each statement and see whether they are true or not.

The first statement is not true. Only one of the figures (square pyramid) has at least one triangular face. It has 4 triangular faces, actually.

The second statement is not true. Only one of the figures is a rectangular prism. The remaining two are triangular pyramid and triangular prism respectively.

The third statement is not true also. Only 1 figure is a triangular prism.

The fourth statement is correct. In group 1, all the figures has at least one square face.

Answer:

$179.1

Step-by-step explanation:

Total area to be painted = 2,250 sq.ft

area covered by per gallon of paint = 250 sq.ft

Hence, gallons of paint required to paint 2,250 sq.ft is...

2250/250 = 9

so, 9 gallons of paint are required to paint 2,250 sq.ft

cost per gallon of paint = $19.90

so, cost of 9 gallons is...

19.90*9 = 179.1

The total money that Kathy will spend for painting the outside of her house is $179.1.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given is the Kathy who is painting the outside of her house. Its area is 2,250 square feet. Each gallon of paint covers 250 square feet and costs $19.90.

Area of the outer house = [A] = 2250 ft²

Area covered by 1 gallon of paint = [a] = 250 ft²

Therefore, the total gallons of paint needed = (2250/250) = 9 gallons.

Cost of 9 gallons of paint will be = 19.90 x 9 = 179.1

Therefore, the total money that Kathy will spend for painting the outside of her house is $179.1.

The candle burns at a rate of 1 inch per hour.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

here, we have,

Given,

A 12-inch candle burns down in 12 hours.

∴ The rate at which it burns per hour is the total length of the candle divided by the total time it brunt for which is,

= (12/12) inch/hr.

= 1 inch/hr,

Hence, The candle burns at a rate of 1 inch per hour.

Answer:

The answer above me is wrong, it is C, red triangle.

Step-by-step explanation:

Got it right on a school test.

The red triangle represents the reflection ABC across the y-axis. Option C is correct.

It is described as the modification of both the geometric body's coordinates and form. A two-dimensional transformation is another name for it. Geometric transformations allow for the rotation, translation, reflection, and glide translation of the geometry.

We have to find the triangle that represents the reflection ABC across the y-axis.

A flip is a term for a reflection in geometry. The form is mirrored in a reflection. The line of reflection is a line across which an image will reflect. Every point in a figure is said to mirror the other figure if and only if it is equally spaced from every corresponding point in the other figure.

Since the green and blue triangles are equidistant from the y-axis. The red triangle will represent the reflection ABC across the y-axis

Thus, option C is correct.

Answer: D. - 9

Step-by-step explanation:

Give the following :

Starting temperature = - 4°F

At the end of the experiment, the change in temperature was -5°F

What was the final temperature?

Taking the difference of the starting temperature and the final temperature should give the change in temperature over the course of the experiment.

Δtemperature = (final temperature - initial temperature)

Δtemperature = - 5°F

Initial /starting temperature = - 4°F

Hence,

-5 = final temperature - (-4)

-5 = final temperature + 4

Final temperature = - 5 - 4

Final temperature = - 9

QS =25

Step-by-step explanation:

QR + RS = QS

18 + (x-11) =2x-11

7 +x =2x -11

18=x

Plug in x

2(18) -11

36-11

QS=25

18 + (18-11) = 2(18)- 11

18+ 7 = 36 -11

25= 25

True

Answer:

QS=QR+RS

2x-11= 18+x-11

2x-x= 18

x= 18

QS=2*18-11

Step-by-step explanation:

if this answers it or it is just 12

The least common multiple of these two denominators 6 and 12 is 2.

To find the least common multiple (LCM) of the denominators 6 and 12, follow these steps:

Step 1: Prime factorize each denominator.

6 = 2 × 3

12 = 2 × 2 × 3

Step 2: Identify the highest power of each prime factor.

In this case, the highest power of 2² is 2 and the highest power of 3 is 3.

Step 3: Multiply the highest powers of all prime factors.

[tex]2^2 * 3^1 = 4 * 3 = 12[/tex]

Therefore, the LCM of the denominators 6 and 12 is 2.
