=> These 2 multiplication facts are equal to 48.
what is the equation of the given line ( 1,5) and (3,5)
A.)Y=5
B.)X=3
C.)Y=3
D.)X=1
Answer:
A) y = 5
Step-by-step explanation:
Points: (1, 5) and (3, 5)
Slope:
m=(y2-y1)/(x2-x1)
m=(5-5)/(3-1)
m=0/2
m = 0
Since 0 is the slope, that means there's no slope.
y - y1 = m(x - x1)
y - 5 = 0(x - 1)
y - 5 = 0
y = 5

A triangle has an area of 40 cm². The base and height are scaled by a factor of 4. The area of the resulting triangle is ___ square cm.
Answer:
640 cm ^2
Step-by-step explanation:
40x4x4 = 640
let's say b = 20 and h = 4
1/2(20)(4) = 40
scale by 4
b= 80 h = 16
1/2(80)(16) = 640

"Use the Pyhthagorean Theorem to find the missing side of the right triangle" Please help!
Answer:
9
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 40^2 = 41^2
a^2 + 1600 = 1681
a^2 = 1681 - 1600
a^2 = 81
a = 9

To the nearest hundreth, what is the length of line segment AB?
1.) 2.45
2.) 2.16
3.) 7.75
4.) 8.25
Answer:
option (4)
Step-by-step explanation:
Calculate the length using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = A(2, 2) and (x₂, y₂ ) = B(- 6, 4)
AB = [tex]\sqrt{(-6-2)^2+(4-2)^2}[/tex]
= [tex]\sqrt{(-8)^2+2^2}[/tex]
= [tex]\sqrt{64+4}[/tex]
= [tex]\sqrt{68}[/tex]

A pizza pan is removed at 9:00 PM from an oven whose temperature is fixed at 425°F in a room that is constant 74°F. After 5 minutes, the pizza pan is at 300 °F
A) at what time is the temperature of the pan 130°F ?
B) determine the time that needs to elapse before the pan is 180°
Answer:
9:11:48 p.m
9.8 minutes
Step-by-step explanation:
We Obtian the slope of the relation :
Slope = Rise / Run
(0, 425) ; (5, 300)
x2 = 0 ; y2 = 425 ; x1 = 5 ; y1 = 300
(425 - 300) / (0 - 5)
125 / - 5
= - 25
The intercept :
y = mx + c
425 = - 25(0) + c
425 = 0 + c
c = 425
The equation becomes :
y = - 25x + 425
Temperature at 130
130 = - 25x + 425
130 - 425 = - 25x
-295 = - 25x
x = 11.8
9:00 + 11.8 = 9:11:48 p.m
B.)
180 = - 25x + 425
180 - 425 = - 25x
-245 = - 25x
x = 9.8 minutes
I need so much help ☹️
Answer:
666mm
Step-by-step explanation:
A= 1/2 Base x Height . For triangle
A= 1/2 (10)(12)
A=1/2 (120)
A=60 . One triangle is 60, so 2 triangles are 120 mm
Rectangle
A= BxH
A=(14)(13)
A=182mm But since there are 3 triangles you multiply 182 times 3
(182x3)+120
=666
Area of the figure is 666mm
One angle of a triangle measures 95° the other two angles are in a ratio of 7:10 what are the measures of those two angles
Answer:
35 degrees and 50 degrees
Step-by-step explanation:
The sum of all the angles in a triangle must be 180 degrees. So 180 - 95 = 85 leftover for the other two angles. Since we have a ratio of 7:10, we can add that up to get 17 total pieces of that 85-degree angle. 85 / 17 = 5, so each piece is 5 degrees. Therefore, the other two angles are 7*5 = 35 degrees and 10*5 = 50 degrees.

I don't understand this my teacher is not texting me back
Answer:
Please find below. Fill in the table with the values of y given below.
Step-by-step explanation:
For question 5, you should substitute the different values of x into the equation y =x^2 +4
So, when
x = -3, y = (-3)^2 +4 = 9+4 = 13
x = -2, y = (-2)^2 +4 = 4+4 = 8
x = -1, y = (-1)^2 + 4 = 1+4 = 5
x = 0, y = 0^2 + 4 = 4
x = 1, y = 1^2 +4 = 1+4 = 5
x = 2, y = 2^2 +4 = 8
x = 3, y = 3^2 + 4 = 13
x = 4, y = 4^2 + 4 = 20
For question 6, you need to find the nth term or a formula of y in terms of x.
For this, find the common difference between each of the consecutive values of y.
This is 5
So, the start if our equation is going to be ‘y = 5x’
Now, to find the ‘+c’ part, can be calculated by substituting the value of y when x = 1 into the y = 5x
So,
y = 5x + c
13 = 5 + c
Rearrange the find that c = 8
Therefore, the nth term formula = 5x + 8
Hope this helps
 please help me ahhh im doing 8th grade math with pythagorean theorem
Step-by-step explanation:
The pythagorean theorem is the sum of the two legs squares equal the hypotenuse squared.
The hypotenuse is the longest side so 3.5 is our hypotenuse.
Apply formula to see of true.
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
[tex] {2.5}^{2} + {3}^{2} = {3.5}^{2} [/tex]
[tex]6.25 + 9 = (3.5 {}^{2}) {?} [/tex]

The volume of a cylinder is 980 in cubed.
The height of the cylinder is 20 in. What is the radius of the cylinder?
Express your answer to the nearest hundredth.
9514 1404 393
Answer:
3.95 in
Step-by-step explanation:
The volume is given by ...
V = πr²h
Solving for radius, we get ...
r = √(V/(πh))
For the given numbers, the radius is ...
r = √(980 in³/(π·20 in)) = 7/√π in ≈ 3.95 in
The radius of the cylinder is about 3.95 inches.
Simplify: 14 - ³√216
