An average adult giraffe is 18 feet tall. A newborn giraffe is about 6 feet tall/ Kayla is building a model of a mother giraffe and her newborn. She wants the model to be no more than 17 inches high.
Answer:
Mother = 17 inches and then Newborn = 5 (2/3) or 5.66666666667 inches
Step-by-step explanation:
I was sort of guessing based on your question what you were looking for. How I solved this is we know that since the average adult giraffe is 18 feet tall and the average newborn giraffe is 6 feet tall, then the adult giraffe is about 3 times as tall as the average newborn giraffe so the ratio is 3:1 adult: newborn. So with the mother at 17 inches, then since the newborn giraffe is, on average, 3 times smaller than the mother, it is therefore 17/3 = 5.666667 or 5 and 2/3s.

The speed of 10 cars on a certain highway stretch was recorded below. If the mean of the data is 63.2 with a standard deviation of 6.2, circle all data values with a z-score less than 0.5.
{49, 58, 60, 63, 64, 64, 65, 67, 70, 72}
Answer:
Data values: 63, 64, 64, 65
Step-by-step explanation:
[tex]Z=\frac{x-\mu}{T}\ or\ Z=\frac{\mu-x}{T}[/tex]
a.
[tex]0.5 = \frac{x-63.2}{6.2}[/tex]
x - 63.2 = 0.5 × 6.2
x = 66.3
b.
[tex]0.5 = \frac{63.2-x}{6.2}[/tex]
63.2 - x = 0.5 × 6.2
x = 60.1
values that falls within 60.1 < x < 66.3
= 63, 64, 64, 65

You are going to draw 4 cards from a standard deck of 52 cards. How many different combinations of cards could you draw?
Answer:
Step-by-step explanation:
To start with we can consider how many possibilities there are for the first card which is obviously 52, as any one of the cards in the deck can be found on the top of the pile. The next card is a bit trickier as there are only 51 possible cards that it could be as the first card takes up a spot. The third card now only has 50 possible cards it could and this continues all the way down to the last card.

The base of a hexagonal prism has an area of 82 square inches. The height of the prism is 9 inches. Find the volume of the prism.
Answer:
738 cubic inches
Step-by-step explanation:
V=B*H
B=base area
H is height
82*9=738
The volume of the Prism is 738 cubic inches.
What is Prism?Prism is "3 dimensional shape with two identical shapes facing each other".
According to the question,
The base of prism (b) = 82 square inches.
The height of prism (h) = 9 inches
Formula for Volume of prism = base of the prism × height of the prism
= 82 × 9
= 738 cubic inches.

How to I solve this Area Problem for 7th grade?
Answer:
A. The area of the bottom of the round pan is greater than the area of the bottom of the rectangular pan by about 8.5 square inches
Step-by-step explanation:
Area of Circle Pan: A = 3.14 * r^2
(3.14 will be used for Pi)
A = 3.14 * 5^2
A = 3.14 * 25
A = 78.5
Area of Rectangle Pan: A = l * w
A = 10 * 7
A = 70
Difference of the Areas (to compare them)
78.5 - 70 = 8.5
A. The area of the bottom of the round pan is greater than the area of the bottom of the rectangular pan by about 8.5 square inches

(b) Use the model in part (a) to find the fraction of Jada’s garden that is made up of beefsteak tomatoes. Explain your answer.
Answer:
(c) Write an equation to find the fraction of Jada’s garden that is made up of beefsteak tomatoes.
Answer:
Answer:
8/15
Step-by-step explanation:
The problem states that Jada has a vegetable garden made up of 2/3 tomato plants, of which 4/5 are beefsteak tomatoes. Therefore, to determine the portion of the garden that is made up of beefsteak tomatoes, both fractions must be unified in the same common divisor.
Thus, since the common least multiple of 3 and 5 is 15 (3 x 5), the fraction 2/3 can be calculated as 10/15. In turn, of those 10, 4/5 are beefsteak tomatoes, which can be calculated as 8/10, since the common lower multiple of 5 and 10 is exactly 10.
Therefore, 8/15 of Jada's vegetable garden are beefsteak tomatoes.

Answer:
The average change in temperature per hour was -8°F.
Step-by-step explanation:
Using the equation 48-(-16) we know that the temperature dropped by 64°F.
[tex]48-(-16)=64[/tex]
We now know that the temperature dropped by 64°F in a period of 8 hours. Using the equation -64/8 we can find the average change in temperature per hour.
[tex]\frac{-64}{8} = -8[/tex]
Therefore, the average change in temperature per hour was -8°F.

In the diagram, AB, BC, CD, DE, EF, FG, GH, and HK all have lengths 4, and all angles are right angles, with the exception of the angles at D and F.
Determine the length of DF.
Answer:
5.66 length (3s.f.)
Step-by-step explanation:
[tex] \sqrt{4 {}^{2} + 4 {}^{2} } [/tex]
= 5.65685
= 5.66 (3 s.f.)
By using the Pythagorean theorem, we will see that the length of DF is 5.7 units.
How to get the length of DF?
We can make a right triangle with the sides: DE, FE, and DF.
Such that we know that:
DE = FE = 4
These two are the cathetus of the right triangle.
Then DF is the hypotenuse.
Now, remember the Pythagorean theorem, it says that the sum of the squares of the cathetus is equal to the square of the hypotenuse, then we have:
(DE)^2 + (FE)^2 = (DF)^2
4^2 + 4^2 =(DF)^2
√32 = DF = 5.7
The length of DF is 5.7 units.

Given m\parallel nm∥n, find the value of x and y.
Answer:
See below ↓↓
Step-by-step explanation:
Finding x
Both the angles containing the x variable are on the same side of the transversalThere is a property which states that : two angles on the same side of the transversal are supplementaryTherefore, they add up to 180°⇒ 8x + 12 + 2x + 18 = 180⇒ 10x + 30 = 180⇒ 10x = 150⇒ x = 15Finding y
The angles at the top are vertically opposite angles (VOA), meaning that they are equal⇒ 8x + 12 = 3y - 18⇒ 3y = 8(15) + 12 + 18⇒ 3y = 120 + 30⇒ 3y = 150⇒ y = 50Euge quiere comprar tres remeras, cuatro pares de medias, una campera y dos pantalones.

I buy a bed which normally costs £270 on a scheme where the price of the bed is increased by 60% but I only pay back £18 a month.
How long will it take to fully purchase the bed?
Answer:
it would take 2 years or 24 months
Step-by-step explanation:
60 percent of 270 is 162 add that to 270 and you get 432 divide that by 18 because that's what you're paying every month and you get 24 which is the numbe rof months it will take you to pay the bed off.
To cross check we can multiply 18 and 24 and you get 432.
Answer:
=432
Step-by-step explanation:
270-60%=162
162+270=432
432÷18=24
24×18=432
What value of x makes the equation 4x + 5 = 11 true?

12/2 + 5 = 11
6 + 5 = 11
11 = 11
Therefore,the answer is D.
