4. Overall, there are 45 students.
13 students achieved a mark over 65
[tex]\frac{13}{45} *100[/tex] = 29%
Therefore the answer is b. 29%
5. b is incorrect.
This is because retrievers account for 10% of the dogs, not 15%.
100%-(35% + 45% + 10%) = 10%

what strategy can be used to transform a quadratic function in vertex form to standard form
Hello, I Am BrotherEye
Answer:
This Transparent inquisition can be solved Below
Use transformations to graph a quadratic function in vertex form. A quadratic function in standard form, f(x) = ax² + bx + c, can be changed into vertex form by completing the square. The vertex form of a quadratic function is f(x) = a(x – 5)2 + k, where the vertex of the function is (h, k).
Step-by-step explanation:
Vertex form to standard form converter
Write the parabola equation in the vertex form: y = a*(x-h)² + k ;
Expand the expression in the bracket: y = a*(x² - 2*h*x + h²) + k ;
Multiply the terms in the parenthesis by a : y = a*x² - 2*a*h*x + a*h² + k ;
Best Of Luck

4=2/9x A) 6 B) 9 C) 15 D) 18
Answer:
D. 18
Step-by-step explanation:
multiply both sides by 9/2, the reciprocal of 2/9.4×(9/2)=x
express 4×(9/2) as a single fraction.4×9/2=x
multiply 4 and 9 to get 36.36/2=x
divide 36 by 2 to get 18.18=x
swap sides so that all variable terms are on the left hand side.x=18
Answer:
D 18
Step-by-step explanation:
you devide 4 by 2/9 and get your answer
which set of sides will NOT make a triangle?
19cm 14cm 7cm
11cm 13cm 3cm
12cm 7cm 5cm
2cm 3cm 4cm
Answer:
12cm 7cm 5cm
Step-by-step explanation:
Since 7 + 5 is = 12, it cannot be a side of a triangle. If you add any 2 numbers, the sum must be greater than the 3rd one.
How do you do this what the answer to number 12

2(x+3)=x-4 solving equations
Answer:
X=-10 most likely
Step-by-step explanation:
2x+6=x-4
2x-x=-6-4
X=-10
Answer:
x= -10
Step-by-step explanation:
2(x+3) = x-4
Distribute to simplify left side, 2x+6= x-4-x both sides, x+6= -4subtract 6 both sides, x=-10Can anyone help me please ?

Barry carefully measured all three sides of the triangle and the dimensions were as follows: 7 meters, 8 meters, 10 meters. Was it a Right Triangle? Please help!
Answer: Not a right-angled triangle
Step-by-step explanation:
Given
The sides of a triangle are [tex]7\ m, 8\ m, \text{and}\ 10\ m[/tex]
For a right-angle triangle, it must satisfy the Pythagoras theorem
[tex]a^2+b^2=c^2[/tex]
i.e. the square of the larger side must be equal to the sum of the square of the remaining two sides
Here,
[tex]\Rightarrow 7^2+8^2\ ?\ 10^2\\\Rightarrow 49+64\ ?\ 100\\\Rightarrow 113\neq 100[/tex]
Therefore, it is not a right-angle triangle

(5y+1)²-4(y-1)² how to solve it
Answer:
[tex](5y + 1)^{2} - (2(y - 1))^{2} [/tex]
Step-by-step explanation:
1) Rewrite it in the form a² - b², where a = 5y + 1 and b = 2(y - 1 ).
[tex](5y + 1) ^{2} - (2(y - 1)) ^{2} [/tex]
2) Use multiplication Distributive Property: (xy)^a = x^a y^a.
[tex](5y + 1)^{2} - {2}^{2} (y - 1 {)}^{2} [/tex]
3) Simplify 2² to 4.
[tex](5y + 1 {)}^{2} - 4(y - 1 {)}^{2} [/tex]
4) Rewrite it in the form a² - b², where a = 5y + 1 and b = 2(y-1).
[tex](5y + 1 {)}^{2} - (2(y - 1))^{2} [/tex]
Therefor, the answer is ( 5y + 1 )² - (2( y - 1 ))².

The total bill for drinks and a pizza for three people is $14.90 before tax. The group wants to leave a 15% tip on the cost of the food, not including tax. What will be the amount of the tip?
Answer:
$2.24
Step-by-step explanation:
Since we are trying to find a percentage of something, we can multiply whatever we're trying to find a percentage from by 0.X where X is equal to the number of the percentage. So in this case it's 15%. We can multiply $14.90 by 0.15 and we get 2.23500. Since we cannot have 2.235 dollars, we must round up decimal places.
The tip would be 2 dollars and 24 cents. ($2.24).
