Jada’s friend has a dog that weighs 90 pounds.
Here is a diagram Jada drew that represents the weight of her friend’s dog and the weight of her puppy.
How many TIMES greater is the dog's weight, compared to the puppy?
Compare the weight of the puppy and the dog using fractions.
Compare the weight of the puppy and the dog using percentages.
Answer:
1. 1.1 times the weight of the puppy
2. 11/10
3. %110
Step-by-step explanation:
11 x 9 = 99
99/90=1.1
1.1 = 11/10 = %110
What he said ^^
1. 1.1 times the weight of the puppy
2. 11/10
3. %110
Step-by-step explanation:
11 x 9 = 99
99/90=1.1
1.1 = 11/10 = %110

Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept.
Acidity is measured on the pH scale. The acidity of a substance is given by pH=−logH, where H is the concentration of Hydrogen ions. If a substance has a pH of 6, which equation could be used to find its H value?
Answer:
[H^+] = Antilog[-6]
Step-by-step explanation:
Even though the question is incomplete, let us try to correctly derive the equation used to find the hydrogen ion concentration.
pH=−log[logH^+]
-pH = log[H^+]
[H^+] = Antilog[-pH]
Since pH =6
The equation is;
[H^+] = Antilog[-6]
Answer:
logH=−6
Step-by-step explanation:
Substituting the given value into the formula: 6=−logH; −6=logH; 10−6=H; H=0.000001. The equation logH=−6 is a step in the process of finding the H value.

Pls help with #14 and #15!!!Asap 15 points
Answer:
14. -g + 10, 15. 12k + 3
Step-by-step explanation:
I'm assuming you want to simplify the equation. For 14, we distribute -2. This gets us -2g + 10 + g. We can simplify that to -g + 10. We can't simplify that, so our answer is complete. For 15, we combine 8k and 4k to get 12k + 3. That can't be simplified, so we are done.
Find the constant of variation when y=6 varies directly with x=3
Answer:
The constant of variation is 2
Step-by-step explanation:
The equation of the direct variation is y = k x, where k is the constant of variation
Let us solve the question
∵ x and y are in the direct variation
→ Use the form of the equation above
∴ The equation of variation is y = k x
∵ x = 3
∵ y = 6
→ Substitute them in the equation above
∴ 6 = k (3)
∴ 6 = 3k
→ To find k divide both sides by 3
∵ [tex]\frac{6}{3}[/tex] = [tex]\frac{3k}{3}[/tex]
∴ 2 = k
∵ k is the constant of variation
∴ The constant of variation is 2

Answer:
249x + 1y = 250
Step-by-step explanation:
Answer:
5x + 2y = 250 pencils
Step-by-step explanation:
5 represents the amount in each small box.
2 represents the amount in each large box.
Therefore once you multiply by 5 and x, then multiply by 2 and y you should get the total amount of pencils for the pencils in small boxes and the amount for large sepretally. Then you'd add both of the digits to get the total pencils in all
Describe the slope of the line. (-3,1) and (2,-2) The slope is _____, find the slope m=?
Answer:
[tex]m = - \frac{3}{5}[/tex]
Step-by-step explanation:
The slope of the line is -3/5 which line passes through points (-3,1) and (2,-2).
What is the slope of the line?The slope of the line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2.
Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
Given,
The line passes through the points (-3,1) and (2,-2)
We have,
x₁ = -3, y₁ = 1
x₂ = 2, y₂ = -2
∵ Slope m = (y₂ - y₁)/(x₂ -x₁ )
Substitute the above values in the formula, and we get
The slope of the line = (-2 - 1) / (2 - (-3))
The slope of the line = (-2 - 1) / (2 +3)
The slope of the line = -3/5
Thus, the slope of the line is -3/5 which line passes through points (-3,1) and (2,-2).

Answer: [tex]\frac{8x^3}{27y^6}[/tex]
This is the fraction 8x^3 all over 27y^6
On a keyboard, we can write it as (8x^3)/(27y^6)
===========================================================
Explanation:
The exponent tells you how many copies of the base to multiply with itself.
We'll have three copies of [tex]\left(\frac{2x}{3y^2}\right)[/tex] multiplied with itself due to the cube exponent on the outside.
So,
[tex]\left(\frac{2x}{3y^2}\right)^3 = \left(\frac{2x}{3y^2}\right)*\left(\frac{2x}{3y^2}\right)*\left(\frac{2x}{3y^2}\right)\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{2x*2x*2x}{(3y^2)*(3y^2)*(3y^2)}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{(2*2*2)*(x*x*x)}{(3*3*3)*(y^2*y^2*y^2)}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{8x^3}{9y^6}\\\\[/tex]
-------------------
Or another approach you could take is to cube each component of the fraction. The rule I'm referring to is [tex]\left(\frac{a}{b}\right)^c = \frac{a^c}{b^c}[/tex]
Applying that rule will lead to:
[tex]\left(\frac{2x}{3y^2}\right)^3 = \frac{(2x)^3}{(3y^2)^3}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{2^3*x^3}{3^3*(y^2)^3}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{8x^3}{27y^{2*3}}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{8x^3}{27y^6}\\\\[/tex]
Either way you should get 8x^3 all over 27y^6 as one fraction.

Which of the following are polynomials?
A. x^2 + x + 1/x^2 + 1
B. 2/x^3 + x + 1/2
C. 2/3x^2 + x + 1
D. x^2/3 + 0x + 1
E. x^3 + 2x + square root of 2
Answer:
The polynomials are:
[tex]\frac{2}{3}[/tex] x² + x + 1 ⇒ C
x³ + 2x +√2 ⇒ E
Step-by-step explanation:
A polynomial: is an expression consisting of variables and coefficients, with the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables
A polynomial never division by a variableA polynomial could be one term, and it could be just a constantLet us solve the question
∵ The polynomial never division by a variable
∵ Answer A and B have a division in variable ⇒ ( [tex]\frac{1}{x^{2}+1 }[/tex] , [tex]\frac{2}{x^{3}}[/tex] )
∴ Answers A and B are not polynomials
∵ The polynomial has integer exponents of variables
∵ Answer D has a fraction exponent of x ⇒ [tex]x^{\frac{2}{3}}[/tex]
∴ Answer D is not a polynomial
∵ [tex]\frac{2}{3}[/tex] x² + x + 1 has a non-negative integer exponent of x
∵ There is no division by x
∴ [tex]\frac{2}{3}[/tex] x² + x + 1 is a polynomial
∵ x³ + 2x +√2 has a non-negative integer exponent of x
∵ There is no division by x
∴ x³ + 2x +√2 is a polynomial
∴ The polynomials are [tex]\frac{2}{3}[/tex] x² + x + 1 and x³ + 2x +√2

What is the missing numerator? blank over five plus eighteen over twenty equals thirty over twenty 8 5 3 2
Given:
[tex]\dfrac{?}{5}+\dfrac{18}{20}=\dfrac{30}{20}[/tex]
To find:
The missing value.
Solution:
Let x be the missing value.
We have,
[tex]\dfrac{x}{5}+\dfrac{18}{20}=\dfrac{30}{20}[/tex]
[tex]\dfrac{x}{5}+\dfrac{9}{10}=\dfrac{3}{2}[/tex]
Subtract [tex]\dfrac{9}{10}[/tex] from both sides.
[tex]\dfrac{x}{5}=\dfrac{3}{2}-\dfrac{9}{10}[/tex]
[tex]\dfrac{x}{5}=\dfrac{15-9}{10}[/tex]
[tex]\dfrac{x}{5}=\dfrac{6}{10}[/tex]
[tex]\dfrac{x}{5}=\dfrac{3}{5}[/tex]
Multiplying both sides by 5, we get
[tex]x=3[/tex]
So, the missing value is 3.
Therefore, the correct option is C.
A kid’s bicycle costs $110.00 at a department store, who is offering a 15% off coupon. Determine the final price of the bike after both the discount and 6.25% sales tax.
Answer:
103.125
Step-by-step explanation:
110.00 times 15% = 16.5
16.5 times 6.25% = 103.125
Answer - 103.125
Answer:
With the coupon and sales tax, the bicycle costs $100.38.
Step-by-step explanation:
First, we need to find 6.25% of $110.
110 x 0.0625 = 6.88
Now, let's add this to the total, or $110.
110 + 6.88 = $116.88
After that, we need to find 15% of this total.
116.88 x 0.15 = 17.53
Now, we need to subtract this from the total, which is now $116.88.
116.88 - 16.5 = $100.38
Now, with the coupon and sales tax, the bicycle costs $100.38.
