Answer:
10%
Step-by-step explanation:
The multiples of 2 are 2,4,6,8,10, and so on
The multiples of 5 are 5, 10, 15, 20 , 25, and so on
It is evident that the only one that matches up between 1-10 is 10.
There are 10 options, and our chances are random. There is only 1 option for it to be a multiple of both 2 and 5. Therefore, the probability is 1/10, or 10%
An object flies 450 m/s. How many meters will is
travel in one hour?
Answer:
1,620,000 meters
Step-by-step explanation:
Speed- 450 meter----- 1 second
1 minute = 60 seconds
60 minutes (1 hour) = 3600 seconds
Distance in 1 hour
1 ------ 450
3600---- X
X= 3600 x 450
x= 1,620,000 meters

I used half the sugar to make cookies then I used another 2 cups for a really big cake I had 4 cups of sugar left how many cups of sugar did I start with
Answer:
12 cups of sugar
Step-by-step explanation:
Total cups of sugar = x
Cookies = 1/2x
Big cake = 2 cups
Sugar left = 4 cups
x = 1/2x + 2 + 4
Collect like terms
x - 1/2x = 6
1/2x = 6
Divide both sides by 1/2
x = 6 ÷ 1/2
= 6 × 2/1
= 12/1
x = 12 cups of sugar

i’ll give u brainliest!! what is the area of shape 1 2 and 3
Answer:
Shape 1: 197.04
Shape 2: 125.44
Shape 3: 62.72
Step-by-step explanation:
For shape 1, you first need to find the radius to then find the area of a circle. Which is 394.08. Since this isn't a full circle, you will need to divide it by 2 to get 197.04. For shape 2(Easiest to find) You do 11.2*11.2 to get the answer of 125.44. And lastly for shape 3, you can basically do the same as what you did for shape 2. But since it is a triangle, you divide your answer by 2, to get the answer of 62.72.

what is the answer to this eqution 3.5(x+2)=-4 ? could you please help me thank you
Answer:
x=-3.14
or -3 with -.5 remainder
Step-by-step explanation:
PEMDAS
Parenthesis Exponent Multiply Divide Add Subtract
parenthesis 3.5*x=3.5x 3.5*2=7
3.5x+7=-4
subtract 7 from both sides
3.5x=-11
divide both sides by 3.5
x=-3.14
or -3 with -.5 remainder
Answer:
x=-22/7
Step-by-step explanation:
multiply 3.5 and x then multiply 3.5 and 2. this will get you 3.5x+7=-4. next you need to subtract the 7 from the -4, resulting in 3.5=-11. finally divide -11 and 3.5, after that you get the answer of x=-22/7 or -3 1/7. if you need decimal form that will be -3.142857

Answer:
C. Mario should have multiplied the x-values by $6.50 to get the y values.
Step-by-step explanation:
Let's do it the way they said. If we were to multiply 1 by 65, it would be $65. If we did the same thing for 2, 2 x 65 is $130. This is incorrect because these values do not match up with the ones on the graph.
Decimal points are important in this case because it completely changes your answer. When you multiply 1 by 6.50, you get 6.50. Which is what's on the graph. Multiply 2 by 6.50 and you'll get $13, and so on.
So now we can conclude that the mistake Mario made was that he multiplied x by the wrong value (65), when it should have been $6.50.
Note: Hope this helps! Good luck on your test. :)

(5x^5) - (80x^3)
factoring
Answer:
Factoring the term [tex](5x^5) - (80x^3)[/tex] we get [tex]\mathbf{5x^3(x-4)(x+4)}[/tex]
Step-by-step explanation:
We need to factor the term [tex](5x^5) - (80x^3)[/tex]
First we can see that [tex]5x^3[/tex] is common in both terms
So, taking [tex]5x^3[/tex] common:
[tex](5x^5) - (80x^3)\\=5x^3(x^2-16)[/tex]
We can write [tex]x^2-16[/tex] as [tex](x)^2-(4)^2[/tex]
[tex]=5x^3((x)^2-(4)^2)[/tex]
Now we can solve [tex](x)^2-(4)^2[/tex] using the formula: [tex]a^2-b^2=(a+b)(a-b)[/tex]
We can write:
[tex]=5x^3((x)^2-(4)^2)\\=5x^3(x-4)(x+4)[/tex]
So, factoring the term [tex](5x^5) - (80x^3)[/tex] we get [tex]\mathbf{5x^3(x-4)(x+4)}[/tex]
Write an equation of the line that is the perpendicular bisector of the line segment having endpoints
(3,-1) and (3,5).
Answer:
Equation of perp/bisector: y = 2
Step-by-step explanation:
The equation of the line that is the perpendicular bisector of the line segment having endpoints (3, -1) and (3, 5) is y = 2.
What is the equation of a line?A straight line's general equation is y = MX + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Key Concept. Y = MX + c represents the equation of a straight line with gradient m and intercept c on the y-axis.Perpendicular bisector:
Lines that cross each side's midpoint and are perpendicular to the specified side are known as a triangle's perpendicular bisectors.Key concept:
Y = MX + c represents the equation of a straight line with gradient m and intercept c on the y-axis.Slope through the indicated points:
(5--1)/(3--3) = undefinedThus, m = 0 is the slope of the perpendicular bisector.Midway along the segment, x = (3+3)/2 = 3 and y = (-1+5)/2 = 2.The midway is (3,2), and the line is horizontal through if slope = 0. (3,2).The equation of the line that is the perp/bisector of the line segment is y=2.
Therefore, the equation of the line that is the perpendicular bisector of the line segment having endpoints (3, -1) and (3, 5) is y = 2.

Of the 80 girls in Joy's class, 24 have blond hair. What percent of girls in Joy's class have blond hair?
Answer:
30%
Step-by-step explanation:
Answer:
15%
Step-by-step explanation:
To determine the percentage of the girls with blonde hair...it means we will have to use this formula
Number of girls with blonde hair/total numbers of girls ×100
Number of girls with blonde hair is 12
Total number of girls is 80
Therefore,12/80 ×100
1200/80
120/8
15
Therefore the percentage of the girls with blonde hair is 15%

(-4,1) (0,5) in slope-intercept form
Answer:
F(x)=1x+5
Step-by-step explanation:
Answer:
y = x + 5
Step-by-step explanation:
(-4, 1) and (0, 5)
To find slope, it's [tex]\frac{y_{2} - y_{1} }{x_{2}-x_{1} }[/tex]
So 5 - 1 / 0 - (-4) -> 4/4 = 1
1 is the slope, so y = x + b.
To find b, plug one of the points into the formula. I'll use (0, 5).
(5) = 1 (0) + b
b = 5
So the equation in slope-intercept form is y = x + 5.
