On a map 3 cm represents 21 km. What is the
length of a road in cm if the actual length of the
road is 105 km?
Answer:
`5 centemeters.
Step-by-step explanation:
Just divide the KM by 7 since 21 divided by 3 is 7. So dividing 105 by 7 gives you 15. HOPE THIS HELPS! :)

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=-10help me with this question please!! no links!!
How to find a tangent ratio
Answer:
The tangent ratio is the value received when the length of the side opposite of angle theta is divided by the length of the side adjacent to angle theta. It is very commonly abbreviated as tan.
(50pts) The distance covered and the time taken by a car are plotted in a graph.
a. Find the slope of the line in the graph.
b. Calculate the distance traveled by the car at the 20th second.
c. Calculate the speed of the car.
Answer:
a=2
b=40m
c=2m/s
Step-by-step explanation:
slope is rise over run so 10/5 simplified is 2/1 or 2
for b just look at the graph at the 20th second
for c you do distance over time so basically the same thing as a 10/5 which is 2m/s

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.

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
How do you do this what the answer to number 12
what multiple of 9 is a factor of 9
Answer:
9
Step-by-step explanation:
Answer:
( 1 ), ( 3 ), ( 9 )
Step-by-step explanation:
Every time you add one to a digit (which is the same as adding 10, 100, 1000, etc) you get a number that is one more than a multiple of 9, so you have to subtract one from the number, which brings the sum of the digits back to 9.
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).
please help me simplify this
Step-by-step explanation:
Given
sin(α+β) cos(α-β) +cos(α+β) sin(α -β)
We can see it is in the formula of
sin(A + B) = sinA cosB + cosA sinB
So now
Sin ( α + β + α - β)
= sin 2α
Or we can write sin2α as
= 2 sin α * cos α
Hope it will help :)❤

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
