Katherine uses $\frac{7}{10}$ of a gallon of red paint to paint $\frac{3}{5}$ of her wall. How many gallons of red paint will she use to paint her whole wall? There is no 5/5
Answer:
1.167 gallons
Step-by-step explanation:
Given that:
Fraction of red paint used = 7/10 of a gallon
Fraction of wall painted = 3/5
Gallon of paint required to paint the entire wall:
Fraction of entire wall = 1/1
7/10 paint = 3/5 wall
x paint = 1 wall
Cross multiply
(3/5)x = 7/10
Divide both sides by 3/5
3/5x ÷ 3/5 = 7/10 ÷ 3/5
(3/5)x * 5/3 = 7/10 * 5/3
x = 35 / 30
x = 7/6 = 1.167 gallons of red paint
Phillipe says he cannot simplify the expression 5^c • 2^c. Complete the statement about Phillipe's claim.
Answer:
Step-by-step explanation:
[tex]a^{m} * b^{m}[/tex] = [tex](ab)^{m}[/tex]
Yes, he can!!
[tex]5^{c} * 2^{c} = (2 * 5 )^{c}[/tex] = [tex]10^{c}[/tex]
For example,
2³ × 3³ = 8 × 27 = 216
6³ = 216
The expression can not be simplified as it do not have same base, and can be written as [tex]10^c[/tex]
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, Phillips says he cannot simplify the expression [tex]5^c.2^c[/tex]
She can not simplify the expression because the bases of the expression are not same, and this expression is same as
[tex]5^c.2^c\\\\= (5.2)^2\\\\=10^c[/tex]
Hence, the expression can not be simplified as it do not have same base, and can be written as [tex]10^c[/tex]

Jason has a lemonade stand but he already made $26 he charges his customers one dollar per lemonade Kaylee has a lemonade stand where she made $16 and she charges the customers two dollars per lemonade which equation shows the number of lemonade, eggs, Kaylee needs to sell to make a higher profit than Jason. A. 26-x<16-2x. B. X+26<2x+16 C. 26+2x>16+x D. 16x+2>26x+1
Answer: B. X+26<2x+16
Step-by-step explanation:
Let x be the number of lemonade Kaylee needs to sell to make a higher profit than Jason.
Given: Jason has made $26. he charge $1 per lemonade.
Total earnings after x lemonades = $26+($1) x
= $(26+x)
Kaylee has made $16. he charge $2 per lemonade.
Total earnings after x lemonades = $16+($2) x
= $(16+2x)
Required inequality : (16+2x)> (26+x)

Write an equation in point slope form of the line passes through the point (3,5) and has a slope of m=-1
Answer:
The answer is y= -1x+8
Step-by-step explanation:
y=mx+b
m= -1
y-y=m(x-x1)
y-5=-1(x-3)
y-5=-1x+3
+5 +5
y=-1x+8
The equation in point slope form of the line passes through the point (3,5) and has a slope of m=-1 is y= -1x+8.
Point Slope Form:
The equation of a straight line that passes through a particular point and is inclined at a specific angle to the x-axis can be found using the point slope form. Every point on a line must satisfy the equation for the line in order for it to exist. This implies that a line is represented by a linear equation in two variables. Depending on the facts at hand, there are different ways to find a line's equation. A straight line is represented using its slope and a point on the line using point slope form. This means that the point slope form is used to find the equation of a line whose slope is "m" and which passes through the points (x 1, y 1). The equation of a straight line can be expressed in various ways.
Point Slope Formula in Math:
y − y1= m (x − x1)
where,
(x, y) is a random point on the line(which should be kept as variables while applying the formula).
(x1, y1) is a fixed point on the line.
m is the slope of the line.
y=mx+c
m= -1
y-y1=m(x-x1)
y-5=-1(x-3)
y-5=-1x+3
y= -1x+8

The angles of a triangle add to 180, add the angles and solve for x
Answer:
x = 14
Step-by-step explanation:
3x + 9 + 5x - 1 + 4x + 4 = 180 because triangles have 180 degrees
12x + 12 = 180
180 - 12 = 168
12x = 168
168/12 = 14

The null and alternative hypotheses are [tex]H_o[/tex] μ= 64.2 and [tex]H_a[/tex]: μ ≠ 64.2 respectively.
What is the hypothesis?In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter. Using sample data, hypothesis testing is performed to examine the plausibility of a theory.
The average height of an 18-year-old American woman is 64.2 inches
Hypotheses state claims about a population parameter.
p: population proportion: population mean
σ: population standard deviation
The null hypothesis asserts that the sample size equals the claim value:
[tex]H_o[/tex] :μ= 64.2
The alternate hypothesis expresses the inverse of the null hypothesis (As per the claim):
[tex]H_a[/tex] : μ ≠ 64.2
μ = The average height of 18-year-old American women in the population.
[tex]H_o[/tex] :μ= 64.2
[tex]H_a[/tex] : μ ≠ 64.2
Thus, the null and alternative hypotheses are [tex]H_o[/tex] μ= 64.2 and [tex]H_a[/tex]: μ ≠ 64.2 respectively.
