Answer:
170 strawberries
Step-by-step explanation:
Let strawberries be x, then:
Ann ate 5x, Ben ate 5x, and Cindy ate 7x
7x+30 = 5x+5x
7x+30 = 10x
30 = 3x
10 = x
5x = 50
7x = 70
total: 50+50+70 = 170

Answer:
13. x = 3∛2
14 x = ± 4√6 = ± 4√2 √3
15. x = 2∛11
16 x = -4∛2
17 x = ± 10√3
18. x = ± 4 √3 √5
Step-by-step explanation:
13. x³ = 54
x = ∛4
Factor 54: 2 x 27
∛54 = ∛2 x ∛27
∛27 = 3
answer: 3∛2
14. x² = 96
x = ±√96
96 = 6 x 16
√16 = 4
√6
√96 = ± 4√6 = ± 4√2√3
15. x³ = 88
x = ∛88
88 = 8 x 11
∛88 = ∛8 x ∛11 = 2∛11
16. x³ = -128 means x has to be negative
x = -∛128
128 = 64 x 2
∛128 = ∛64 x ∛2 = 4∛2
So x = -4∛2
17. x² = 300
=> x = ± √300
300 = 100 x 3
√300 = √100 x √3 = 10√3
x = ± 10√3
18. x² = 240
x = ±√240
240 = 16 x 15
√240 = ± (√16 x √15)
= ± 4 √3 √5

How to find the angle of triangles?From the figure, we can see both are isosceles triangles.From the first figure we can calculate the
angle a= 180-(75+75)=30°
the second figure shows the angle b =60°to confirm that a<b.
An isosceles triangle has two equal sides as well as two equal angles. The Greek words iso (same) and skelos are the source of the name (leg). An equilateral triangle is one in which all of its sides are equal, whereas a scalene triangle is one in which none of its sides are equal.If either of a triangle's two sides is equal, the triangle is said to be isosceles. Let's consider a triangle with the sides AB, BC, and CA. The triangle is isosceles if any of these statements—AB = BC, BC = CA, or CA = AB—are accurate.To more learn about isosceles triangle refers to:

It's Joey's 8th birthday! Joey's favorite present is the 8 baseball cards that he got from his dad. Joey has never owned a baseball card before this gift, and he decides that he wants to start collecting baseball cards.
He plans to collect 3 baseball cards each month until he has a total of 50 cards.
Let x represent the number of months Joey collects the baseball cards.
Which equation can Joey use to determine how many months it will take to reach his goal?
The equation that Joey can use to determine how many months it will take to reach his goal will be 8 + 3x = 50 and the number of months is 14.
How to illustrate the information?From the information, Joey's favorite present is the 8 baseball cards that he got from his dad and he has never owned a baseball card before this gift and he plans to collect 3 baseball cards each month until he has a total of 50 cards.
This will be illustrated as:
8 + 3x = 50
Collect like terms
3x = 50 - 8
3x = 42
Divide through 3
3x / 3 = 42 / 3

You spin a spinner, Flip a coin, then spin the spinner again. Find the probability of the compound event, write your answer as a fraction or percent. If necessary round your answer to the nearest hundredth.The probability of spinning blue, flipping heads, then spinning a one is _
The probability is given by:
[tex]P=\frac{numb\text{er of favourable outcomes}}{\text{total number }of\text{ outcomes}}[/tex]Therefore:
- The probability of spinning blue is:
Favorable outcomes = 1 (blue color)
Total outcomes = 3 (red, blue, and yellow)
[tex]P(\text{spinning blue)}=\frac{1}{3}[/tex]- The probability of flipping heads is:
Favorable outcomes = 1 (head)
Total outcomes = 2 (head and tail)
[tex]P(\text{flipping head)=}\frac{1}{2}[/tex]- The probability of spinning a one is:
Favorable outcomes = 1 (number 1)
Total outcomes = 3 (numbers 1, 2 and 3)
[tex]P(\text{spinning a one)=}\frac{1}{3}[/tex]Next, the probability of the compound event:
[tex]P(\text{compound event)=}\frac{1}{3}\times\frac{1}{2}\times\frac{1}{3}=\frac{1\times1\times1}{3\times2\times3}=\frac{1}{18}[/tex]Answer: the probability of the compound event is 1/18

What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.
From the diagram:
∠J + ∠K + ∠L = 180° (angles in a triangle)
Substituting:
(7x + 2) + (8x) + (4x + 7) = 180
19x + 9 = 180
x = 9
∠J = 7x + 2 = 7(9) + 2 = 65°
∠K = 8x = 8(9) = 72°
∠L = 4x + 7 = 4(9) + 7 = 43°
∠k ≠ 89°

What is the unitary method of problem solving?
The unitary technique, in its most basic form, is used to calculate the value of a single unit from a specified multiple. The unitary approach can be used to complete it. Additionally, after determining the value of a single unit, we can multiply that value by the number of units needed to determine the value of the additional units. The concept of ratio and proportion is mostly applied using this way.
Given, for every 3 pencils, number of pens bought = 2
Therefore, every 1 pencil, number of pens bought = 2/3
Thus, for 21 pencils, number of pens bought = (2/3)*21 = 14
Therefore, total number of pencils and pens bought by Henry = 21 + 14 = 35.

A group of friends take a tubing trip the company charges $15 for a regular tube and $7.50 for a cooler tube. Together they spent $360 to rent. How many of each tube did they rent?
The no. of regular tube costing $15 were 12 and the cooler tube costing $7.5 each were 24
What is a tubing?The entire family can participate in tubing. Change into swimwear, rent a tube and a life jacket, and float down the river—that it's easy. Numerous outfitters provide transportation to the best waterways and rent tubes from Blue Ridge to Columbus, via Helen and Columbus.
The total cost of rent on tube = $360
Price of regular tube = $15
Price of cooler tubes = $7.5
Let the no. of regular tubes be and cooler tubes be y
The equation forms
15x + 7.5y = 360 ...1
As we can notice regular tube is twice the price of cooler tubes, sthe the equation forms
2(7.5) = 15
This means when y = 2, x = 1
cross multiply them and we find
2/y = 1/x
x/y = 1/2
x = y/2 ...2
Putting the value of x in eq 1, we get
15(y)/2 + 7.5y = 360
7.5y + 7.5y = 370
15y = 360
y = 360/15
y = 24
Putting the value of y in eq 1, we get
15x + 7.5(24) = 360
15x + 180 = 360
15x = 360 - 180
15x = 180
x = 180/15
x = 12
Thus, The no. of regular tube costing $15 were 12 and the cooler tube costing $7.5 each were 24.

What is algebraic identities?In mathematics, an identical element, also known as a neutral element, is an element of a set that, when subjected to a binary operation, leaves each element of the set intact. In algebraic structures like groups and rings, this idea is applied. Algebraic identities are algebraic equations that are true regardless of the value of each variable. Additionally, they are employed in the factorization of polynomials. Algebraic identities are employed in this manner for the computation of algebraic expressions and the solution of various polynomials.
Given Data
m + n+ p= 10
mn + np + mp = 27
For m² + n²+ p²
Using algebraic identities,
(m+ n +p)² = m² + n² + p² +2(mn + np + pm)
(10)² = m² +n² + p² + 2(27)
100 = m² + n² + p² + 54
100 - 54 = m² + n² + p²
46 = m²+n²+p²
The value of m²+n²+p² is 46.

7 is the answer but i dont have the work
Answer:
f(-10) = -299999
Step-by-step explanation:
Equation
f(x)= −3x^55+1
Given
x = - 10
Solution
You have to understand what f(x) means. When you put a value in for x, every x on the right is supplied with that value.
In this case I take the equation to mean what ever we are given in the brackets (in this case 10) is what goes into the x on the right. So the new equation is
f(-10) = -3*(-10)^5 + 1
(- 10) ^5 = - 100000
f(-10) = -300000 + 1
f(-10) = -299999
