Answer:
question 2 answer you wrote correct
question 3 answer is 20
Answer:
Q.2: 39, Q.3: 20 cups
Step-by-step explanation:
Q.2 Dog/Cat = 2/3
when Dog = 26,
26/cat = 2/3
cat = 26 x 3 / 2 = 39
Q.3 Sugar/Flour = 3/5
when sugar = 12 cups,

Jennifer is putting together a selection of flowers that has at most 12 flowers in it. She is choosing either roses or carnations. She wants to pick at least three roses and at least two carnations. Let r be the number of roses she uses and let c be the number of carnations she uses. Write a system of inequality’s that represents this scenario.
Answer:
r + c ≤12
r > 3
c > 2
Step-by-step explanation:
Jennifer is putting together a selection of flowers that has at most 12 flowers in it.
r = number of roses she uses
c = the number of carnations
At also means Less than or equal to.
It is represented by ≤
She is choosing either roses or carnations. She wants to pick at least three roses
r > 3
and at least two carnations.
= c > 2
Therefore, the system of inequality that represents this scenario is written as:
r + c ≤ 12
r > 3
c > 2

Andrea and Damian are collecting clothing items to donate. When they begin tracking their progress, Damian already has 5 items collected. Damian's goal is to collect 3 items per day, and Andrea's goal is to collect 4 items per day.
Answer:
5 days
Step-by-step explanation:
Given
Damian
[tex]Base\ Items = 5[/tex]
[tex]Rate = 3[/tex] daily
Andrea
[tex]Rate =4[/tex] daily
Required [Missing from the question]
How long will they get the same number of items
Represent the number of items with x and the days with y.
So:
For Damian
[tex]y = Base\ Items + Rate * x[/tex]
[tex]y = 5 + 3 * x[/tex]
[tex]y = 5 + 3 x[/tex]
For Andrea
[tex]y = Rate * x[/tex]
[tex]y = 4* x[/tex]
[tex]y = 4x[/tex]
Equate both expressions.
[tex]4x = 5 + 3x[/tex]
Collect like terms
[tex]4x - 3x = 5[/tex]
[tex]x = 5[/tex]
Hence, they will have equal amount of items after 5 days

The upper-left coordinates on a rectangle are (-1, 7), and the upper-right coordinates are (4,7). The rectangle has an area of 20 square units. Draw the rectangle on the coordinate plane below.
Answer:
The answer is below
Step-by-step explanation:
The distance between the upper left coordinate and the upper right coordinate is the length of the rectangle. Hence:
[tex]length=\sqrt{(4-(-1))^2+(7-7)^2} =5\ units\\[/tex]
Area = length * breadth
20 = 5 * breadth
breadth = 4 units
The bottom left coordinate would have the same x coordinate as the upper left coordinate. Hence, bottom left coordinate = (-1, y₁)
The distance between the upper left coordinate and the bottom left coordinate is the breadth of the rectangle. Hence:
[tex]breadth=\sqrt{(-1-(-1))^2+(y_1-7)^2} =4\ units\\\\ y_1-7=\pm 4\\\\y_1=4+7=11\ \ or\ y_1=-4+7=3[/tex]
Since it is at the bottom, hence y₁ = 3. Hence bottom left coordinate = (-1, 3)
Bottom right coordinate has same y coordinate as bottom left coordinate and same x coordinate as upper right. Hence bottom right coordinate = (4, 3)

Rectangle ABCD with length 24 feet and width 20 feet is dilated by a scale factor of 4/3. What is the area of rectangle A'B'C'D'?
multiply the length and with by the scale factor:
24 x 4/3 = 32 feet
20 x 4/3 = 26 2/3 feet
Area is length x width:
32 x 26 2/3 = 853 1/3 square feet.

Answer:
a=4.2
Step-by-step explanation:
The constant is 1.4 bc if u divide the numbers in y with the x that corresponds them, it will be 1.4
ex. 2.80 divided by 2 is 1.4
ex. 5.60 divided by 4 is 1.4
This means that
2×1.4 is 2.80
4×1.4 is 5.69 so
3×1.4 is 4.2
*ANSWER ASAP* Earth has a diameter of approximately 7926 miles. Determine the volume of Earth.
Answer:
Rounding to the nearest whole number, 49 moons can fit in the earth.
Rounding to the tenth place, 50 moons can fit in the earth.
Step-by-step explanation:
To find how approximately how many moons could fit inside the earth, you would need yo find the volumes the earth and the moon.
V = 4/3 π r^3
Earth:
d = 2r
d = 7926 miles
7926 = 2r
3963 miles = r
V = 4/3 π (3963)^3
V = 4/3 π (62240377347)
V = 82987169796π cubic miles
Moon:
d = 2r
d = 2159 miles
2159 = 2r
1079.5 miles = r
V = 4/3 π (1079.5)^3
V = 4/3 π (1257963209.88)
V = 1677284279.83π cubic miles
Now you divide the volume of earth by the volume of moon to find how many moons can fit in earth
82987169796π ÷ 1677284279.83π =
approx 49

What is the domain of the function y= (square root) x+4
Answer:
0 ≤ x ≤ ∞
Step-by-step explanation:
Square roots always need to be either equal to or greater than zero because it should be positive inside (unless we're working with imaginary numbers).
So the domain would be that x ≥ 0 (or the third choice ⇒ 0 ≤ x ≤ ∞).
