DV=3√10
Step-by-step explanation:
D(-1,7) and V(8,4)
to determine the length you use the distance formula
d =√(x2-x1)²+ (y2-y1)²
in thhis case
d=√(-1-8)²+(7-4)²
d=√81 +9
d=√90
d= 3√10

Triangle ABC is graphed in Quadrant I of a coordinate plane, and none of the vertices have an x-coordinate or
y-coordinate of 0. Triangle ABC is rotated 90° clockwise with the origin as the center of rotation to create triangle
A'B'C'.
Which statement must be true?
А)
The sum of the angle measures of triangle A'B'C' is 90° more than the sum of the angle measures of
triangle ABC
B The side lengths of triangle A'B'C' are greater than their corresponding side lengths of triangle ABC.
Each angle measure of triangle ABC is less than the corresponding angle measure of triangle A'B'C'.
D. The corresponding sides of triangle ABC and triangle A'B'C' are congruent.
Answer:
Step-by-step explanation:
D. the corresponding sides of triangle ABC and triangle A'B'C' are congruent
because the sides do not change their length when we rotate the triangle

The ratio of the number of model cars that Jim owns to the number of model cars Terrence owns is 8: 6. Terrence owns 36 models cars. How
many model cars does Jim own?
Answer:
Jim owns 48 cars
Step-by-step explanation:
Jim : Terrence
8 : 6
Substitute in the given values;
6x = 36
x = 6
Substitute back to find how many cars Jim owns
8 * 6 = 48
Jim owns 48 cars

Use the order of operations to evaluate the expression. 8+2(3+4)÷2
Answer:
8+2(3+4)÷2 = 10
Step-by-step explanation:
The order of operation is a set of rules that guides how mathematical operations are done, to make for a universal solution.
Let us apply the rules while solving the problem 8+2(3+4)÷2
The rule is summarized in a set of Acronym known as PEMDAS
P - Parenthesis(Bracket) = (3+4) = 7
The expression becomes: 8+2(7)÷4
E - Exponents: this refers to powers, but is absent in this expression
M - multiplication: 8 + (2 × 7) ÷ 4 = 8 + 14 ÷ 7
D - Division: 8 + (14÷7) = 8 + 2
A - Addition = 8 + 2 = 10
S = subtraction. (absent in this expression)
∴ 8+2(3+4)÷2 = 10
3.2y-1.4y+y-0.6y=0.55
Answer:
it is y=0.25
Step-by-step explanation:
because Step 1: Simplify both sides of the equation.
3.2y−1.4y+y−0.6y=0.55
3.2y+−1.4y+y+−0.6y=0.55
(3.2y+−1.4y+y+−0.6y)=0.55(Combine Like Terms)
2.2y=0.55
2.2y=0.55
Step 2: Divide both sides by 2.2.
2.2y
2.2
=
0.55
2.2
Instructions: Find the missing side lengths. Leave your answers as radicals in simplest form.
Given:
A figure.
To find:
The values of x and y.
Solution:
We know that, in a right angled triangle,
[tex]\sin \theta =\dfrac{Perpendicular}{Hypotenuse}[/tex]
[tex]\sin 60^\circ =\dfrac{x}{16}[/tex]
[tex]\dfrac{\sqrt{3}}{2} =\dfrac{x}{16}[/tex]
Multiply both sides by 16.
[tex]\dfrac{\sqrt{3}}{2}\times 16=\dfrac{x}{16}\times 16[/tex]
[tex]8\sqrt{3}=x[/tex]
And,
[tex]\cos \theta =\dfrac{Base}{Hypotenuse}[/tex]
[tex]\cos 60^\circ =\dfrac{y}{16}[/tex]
[tex]\dfrac{1}{2}=\dfrac{y}{16}[/tex]
Multiply both sides by 16.
[tex]\dfrac{16}{2}=y[/tex]
[tex]8=y[/tex]
Therefore, the missing side lengths are [tex]x=8\sqrt{3}[/tex] and [tex]y=8[/tex].
