Answer: [tex]12\ mph[/tex]
Step-by-step explanation:
Given
First cyclist travels [tex]3\ miles[/tex] in [tex]15\ min[/tex]
Then, [tex]7\ miles[/tex] in [tex]35\ min[/tex]
Average speed is given by [tex]=\dfrac{\text{Distance}}{\text{time taken}}[/tex]
[tex]V_{avg}=\dfrac{3+7}{15+35}[/tex]
[tex]V_{avg}=\dfrac{10}{50}=\dfrac{1}{5}\ mile/min[/tex]
[tex]V_{avg}=\dfrac{1}{5}\times 60\ miles/hr[/tex]
[tex]V_{avg}=12\ mph[/tex]
Thus cyclist speed is [tex]12\ mph[/tex]

someone help me with the equation. i’m super confused and don’t know if i’m doing it right
Answer:
I think the answer is (x + 4) • (x + 2)
Step-by-step explanation:
First multiply the coefficient of the first term by the constant
Step 2: Find two factors of 8 whose sum equals the coefficient of the middle term 6
Step 3: write the polynomial splitting the middle term using the two factors found in step 2
Step 4: Add up the first 2 terms, pulling out like factors :
x • (x+2)
Add up the last 2 terms, pulling out common factors :
4 • (x+2)
Step 5: Add up the four terms in step 4
(x+4) • (x+2)
Your final answer is (x + 4) • (x + 2)

This recipe makes 16 portions of potato soup.
Richard follows the recipe but wants to make 4 portions.
Complete the amounts of each ingredient that he needs.
Answer:
24 ml oil
60 g onions
360 g potatoes
400 ml milk
Step-by-step explanation:
The recipe makes 16 portions and you only need 4 portions. Since 16 is 4 times bigger than what you need, just divide everything you've been given by 4.
*you can choose to convert into the correct units of measurement before or after dividing. I converted after dividing. Either way works fine though.
1) 96/4 = 24 ml
2) 240/4 = 60 g
3) 1.44/4 = 0.36 kg
They want it in grams, so times it by 1,000 to convert. this gives you 360 g.
4) 1.6/4 = 0.4 l
They want it in ml, so times it by 1,000 to convert. this gives you 400 ml.

given two consecutive numbers, we are told that twice the first number is twelve more than the second number. What are the two numbers?
Answer: The numbers are 13 and 14
Step-by-step explanation:
Since they are two consecutive numbers, let the numbers be x and x+1.
We are told that twice the first number is twelve more than the second number. This can be expressed as:
2 × x = x+1+12
2x = x+13
2x-x = 13
x = 13
Since x = 13, x+1 = 13+1 = 14
The numbers are 13 and 14

Which of the following terms have a GCF of 6x^3? Select two options. 12p^3r 27p^4q 45p^3q^6 54p^3 63p^3q^6
Answer:
A. and D. are correct
Step-by-step explanation:
The correct answers are Option A, Option D.
The terms which have the GCF of [tex]6x^3\\[/tex] are [tex]12p^3r[/tex] and [tex]54p^3[/tex].
Given data:
To find the greatest common factor (GCF) of the given terms, we need to find the highest power of x that divides into all the terms and the highest power of p that divides into all the terms.
For [tex]12p^3r[/tex] , the highest power of x that divides into this term is [tex]x^0[/tex](since x^0 = 1), and the highest power of p that divides into this term is [tex]p^3[/tex]. Therefore, the GCF is [tex]1 * p^3 = p^3.[/tex]
For 54p^3, the highest power of x that divides into this term is [tex]x^0[/tex] (since x^0 = 1), and the highest power of p that divides into this term is [tex]p^3[/tex]. Therefore, the GCF is [tex]1 * p^3 = p^3.[/tex]
Hence, the terms are [tex]12p^3r[/tex] and [tex]54p^3[/tex].

The shortest leg of a right triangle measures 9 centimeters and the hypotenuse measures 3 centimeters more than the longer leg. Find the length of the hypotenuse. Use the Pythagorean Theorem Formula.
I'm not sure how to set this up
Answer:
The triple is 9, 12, 15
The hypotenuse is 15.
Step-by-step explanation:
Pythagorean Theorem Formula: a²+b²=c² where a & b are the short legs and c is the hypotenuse.
9²+b²=(b+3)²
81+b²=(b+3)²
Small list of the Pythagorean Triples that contain 9:
9,12,15
9,40,41
So as you can see, there are only 2 examples in my list that contain 9 in them. The only one that fits our criteria is the triple, 9, 12 and, 15
You don't need to use the Pythagorean Formula for this as I have just proved.
Answer:
12 cm
Step-by-step explanation:
I don't think u have to use the phytagores theorem b/c the hypotenuse is 9+3=12. but if u have to use this.
[tex] {?a}^{2} + {b}^{2} = {c}^{2} [/tex]
[tex] {9}^{2} + {b}^{2} = {9 + 3}^{2} [/tex]
[tex]81 + {b}^{2} = 9(9 + 3) + 3(9 + 3)[/tex]
[tex]81 + {b}^{2} = 81 + 54 + 9[/tex]
[tex]81 + {b}^{2} = 144[/tex]
[tex] {b}^{2} = 144 - 81 = 63[/tex]
[tex] {b}^{2} = \sqrt{53} = b = 7.93[/tex]
so if u found b then u can find c by using the same formula.
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
[tex] {9}^{2} + {7.93}^{2} = {c}^{2} [/tex]
[tex]81 + 63 = {c}^{2} [/tex]
[tex] {c}^{2} = 81 + 63 = 144[/tex]
[tex] \sqrt{c} = \sqrt{144} [/tex]
[tex]c = 12[/tex]
The base of a right circular cone has a radius of 4 inches and a slant height of 9 inches. If the radius and the slant height are multiplied by 6, by what factor is the surface area multiplied? A. 6 B. 36 C. 24 D. 54
Answer:
Correct option: B -> 36
Step-by-step explanation:
The surface area of a circular cone is given by the formula:
Surface area = pi * radius * (radius + slant height)
If the inicial radius is 4 in and the slant height is 9 in, we have:
Surface area = pi * 4 * (4 + 9) = 52pi in2
The radius and the slant height are multiplied by 6, so we have:
radius = 6 * 4 = 24 in
slant height = 6 * 9 = 54 in
So the new surface area is:
New surface area = pi * 24 * (24 + 54) = 1872pi in2
The factor of the surface areas is:
New surface area / Surface area = 1872pi / 52pi = 36
Correct option: B

Answer:
(D) [tex]5x^7y^2+7x^6y^5-14x^3y^7+51x^2y^9[/tex]
Step-by-step explanation:
A polynomial is said to be in standard form when it is arranged in descending powers of x.
When there are more than one variable, the alphabetical order is followed. For example, if there are variables x and y in the polynomial, x must be in descending order and y will be in ascending order.
From the given options, the polynomial which is in standard form is:
[tex]5x^7y^2+7x^6y^5-14x^3y^7+51x^2y^9[/tex]

Answer:
I=72.9
Step-by-step explanation:
I=PRT When P= the principal=810, R=rate=3% and T=time(by year)=3 years
I=810*3/100*3
I=24.3*3
I=72.9
Answer:
Simple interest/Interest = £72.9
Step-by-step explanation:
We have to find the simple interest at this point.
So use the formula:
I = prt or I = p x r x t
I = amount of interest
P = principal amount (810)
R = interest rate (in years) (.03)
T = amount of time in (years) (3)
All we need to do is multiply.
I = (810)(.03)(3)
I = £72.9
Drag a symbol to the first box and a number to the second box to complete the solution to this inequality. Each number or symbol can be used once or not at all. –2(z + 5) + 20 > 6
Answer:
[tex]z<2[/tex]
Step-by-step explanation:
Given the inequality: [tex]-2(z + 5) + 20 > 6[/tex]
Step 1: Distribute the bracket
[tex]-2(z + 5) + 20 > 6\\-2z-10+20>6\\-2z+10>6[/tex]
Step 2: Subtract 10 from both sides
[tex]-2z+10-10>6-10\\-2z>-4[/tex]
Step 3: Divide both sides by -2
Note that when you divide an inequality by a negative sign, the inequality sign is reversed.
[tex]-2z>-4\\\dfrac{-2z}{-2}< \dfrac{-4}{-2}\\\\$Therefore, $z<2[/tex]
