The ratio of trucks to cars will simply be the reverse of the ratio given. This will be: = 7:3
Answer:
7:3
Step-by-step explanation:
it says what is the ratio of truck to cars so how many trucks are there? 7 trucks . and how many cars are there? 3 cars so it is 7:3 because there are 7 trucks and 3 cars so you put both of them together there is your answer. Ratio's are very easy.
How do I find the y-intercept of a graph?
Answer:
the y intercept on a graph is the line that goes up and down
Step-by-step explanation:
Step-by-step explanation:
Every point on the y-axis has 0 as its x-coordinate. The y-intercept is the point of intersection of the graph and the y-axis.
To find the y-intercept, let x = 0 in the equation of the graph and solve for y. The value of y is the y-intercept.
For example, what is the y-intercept of
2x + 3y = 6
Let x = 0.
2(0) + 3y = 6
Solve for y.
3y = 6
y = 2
The y-intercept is 2.
What is the expression in factored form?
2x^2+16x+24
Is it (x-2)*(x-6) or 2(x-2)*(x-6)?
Answer:
( 2x +4) ( x+6)
Step-by-step explanation:
Explanation:-
Given expression 2 x² + 16 x + 24
The factors of 48 = 12 × 4
⇒ 2 x² + 16 x + 24
⇒ 2 x² + 12 x + 4x + 24
⇒ 2 x ( x +6 ) + 4( x +6)
⇒ ( 2x +4) ( x+6)

Answer:
49π cm²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 14, so r = 14 ÷ 2 = 7, then
A = π × 7² = 49π cm²
Answer:
49pi cm^2
Step-by-step explanation:
[tex]a = \pi \: {r}^{2} [/tex]
Because the radius is half of the diameter, divide it by 2 to get the radius to place in the formula which is 14 ÷2 = 7
so
A = pi × 7^2
A= pi × 49cm^2
Directed line segment PT has endpoints whose
coordinates are P(-2, 1) and 1(4,7). Determine
the coordinates of pointſ that divides the segment
in the ratio 2 to 1.
Answer:
(2 , 5)
Step-by-step explanation:
point (x,y) that divides the segment PI in the ratio 2 to 1
PD=4 - (-2) = 6 PE/ED=2/1 PE=2ED PE+ED=6 3ED=6 ED=2 PE=4
coordinate of E (2,1) .... 2 is x coordinate of E
DI=7-1=6 DF/FI=2/1 DF=4
coordinate of F (4,5) .... .... 5 is y coordinate of E
CF // PD PC/CI=DF/FI=2/1
C (2,5)
Coordinates of the point intersecting segment PT in the ratio of 2 : 1 will be (2, 5).
Given in the question,
Segment PT with endpoints P(-2, 1) and T(4, 7).Point (h, k) divides the segment in the ratio of 2 : 1.If the endpoints of a segment PQ have been given as[tex]P(x_1,y_1)[/tex] and [tex]Q(x_2,y_2)[/tex] and a point [tex](h,k)[/tex] divides this segment in the ratio of m : n,
[tex]h=\frac{mx_2+nx_1}{m+n}[/tex]
[tex]k=\frac{my_2+ny_1}{m+n}[/tex]
If the extreme ends of a segment PT are [tex]P(-2,1)[/tex] and [tex]T(4,7)[/tex] and a point (h, k) divides this segment in ratio of 2 : 1,
[tex]h=\frac{2(4)+1(-2)}{2+1}[/tex]
[tex]h=2[/tex]
[tex]k=\frac{2(7)+1(1)}{2+1}[/tex]
[tex]k=5[/tex]
Therefore, coordinates of the point intersecting segment PT in the ratio of 2 : 1 will be (2, 5).

Ramona has a booth at a craft show. She sells door
wreaths as a money making project. The booth
costs her $200, and each wreath costs her $10 for
material. If she sells each wreath for $30, how many
wreaths does she have to sell to break even?
Friday, January 8, 2021
Record your answer and fill in the bubbles on
your answer document. Be sure to use the correct
place value
Answer: 10 wreaths
Step-by-step explanation:
First identify the terms.
She has a booth that cost $200. This price will not change thus making it a Fixed cost.
Making a wreath would cost her $10 each time so this is a Variable cost.
She sells the wreath for $30 so this is the selling price.
Breakeven = Fixed Cost / Contribution margin
Contribution margin = Selling price - Variable cost
= 30 - 10
= $20
Breakeven point = 200/20
= 10 wreaths

Find the area of the isosceles triangle.
13 cm is the side length
10 cm is the base length
what is the hight?
and area?
Answer:
The hight length : h
The base length : a
Apply the Pythagorean theorem in the right triangle :
h² = 13² - (10/2) = 144
h = √144 = 12 cm
S = (a x h)/ 2 = ( 10 x 12 )/2 = 60 cm²

Pure salt is made up of sodium and chloride. Each gram
of salt contains 0.393 g of sodium. About how much
sodium is in 55.7 g of pure salt?
24 g
29 g
9 g
90 g
Answer:
21.8901 g
Step-by-step explanation:
Given that:
1 gram of pure salt contains 0.393 g of sodium
1 gram = 0.393g
Gram of sodium in 55.7g of pure salt will be x
1g = 0.393g
55.7g = x
Cross multiply:
x = 55.7 * 0.393
x = 21.8901
55.7 g of pure salt will contain about 21.8901 g of sodium chloride
The triangles are congruent. Find the measure of x.
Match up the sides for each triangle using the little marks through the sides
1 to 1, 2 to 2 and 3 to 3
When you do this you see that x corresponds to c on the first triangle.
The 3 angles in a triangle = 180.
Find c by subtracting A and B from 180
C = 180- 29-63 = 88
Now x = c so x = 88
The answer is C. 88

Ariel makes this model to show a division equation. Which equation matches Ariel's model?
Answer
I think it's the third one :)
Step-by-step explanation:
The requried equation that matches the Ariels model are as follows,
A, 1512 / 8 = 189 and C = 1688 / 8 = 211.
The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
A division of 8 has been showing,
So the expression that matches the division of 8 would be the required expression,
So,
A, = 1512 / 8 = 189 [true]
B, = 1600/80 = 8 [false]
C = 1688 / 8 = 211 [true]
D = 1600 / 2 = 800 [false statment]
Thus, the requried equation that matches the Ariels model are as follows,
A, 1512 / 8 = 189 and C = 1688 / 8 = 211.
