Answer:first fine the perimeter 42cm then do the lenth then width and u get the answer
Step-by-step explanation:
or find it on google
Answer:
length= 14cm and width= 7cm
Step-by-step explanation:
The ratio of the length to width is 2:1 so [tex]\frac{length (l)}{width(b)} =\frac{2}{1}[/tex] The perimeter is the sum of 2 length sides and 2 width sides so [tex]perimeter=length+length+width+width=2length+2width[/tex] Now from the ratio we know [tex]\frac{length (l)}{width(b)} =2[/tex] so [tex]length=2width[/tex] So put that into the perimeter equation[tex]perimeter=2(2width)+2width[/tex] so the perimeter is 42cm[tex]42cm=2(2width)+2width\\42cm=4width+2width\\42cm=6width\\width=7cm[/tex] Since length is twice the width, length is 14 cmWILL GIVE BRAINLIEST find the value of (-4,r), (-8,3), m=-5 (show your work pls)
Answer:
r = -17
Step-by-step explanation:
Slope = -5
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]\frac{3 - r}{-8-[-4]}=-5\\\\\frac{3-r}{-8+4}=-5\\\\\frac{3-r}{-4}=-5\\[/tex]
3-r = (-5)*(-4)
3 - r = 20
-r = 20 - 3
-r = 17
r = -17

.Ahmed is making pancakes, his recipe uses 150g of flour for 8 pancakes. How much flour will he need to make 12 pancakes? Remember to give units in your answer.
Answer:
Ahmed needs 225g of flour to make 12 pancakes.
Step-by-step explanation:
With the information provided, you know that the recipe uses 150g of flour for 8 pancakes and you can use a rule of three to find the amount of flour needed to make 12 pancakes:
150g → 8 pancakes
x ← 12 pancakes
x=(150*12)/8= 225g
According to this, the answer is that Ahmed needs 225g of flour to make 12 pancakes.
A group of cubes are arranged in a pattern with the same number of cubes in each row and column. There are 225
cubes in the shape. How many cubes are in one row?
A)
15
B)
25
0
56
D)
75
Given:
Total number of cubes = 225
Cubes are arranged in a pattern with the same number of cubes in each row and column.
To find:
The number of cubes in a row.
Solution:
Let the number of cubes in a row be x.
Since, cubes are arranged in a pattern with the same number of cubes in each row and column, therefore number of cubes in rows and columns are equal.
[tex]\text{Total cubes}=x\times x[/tex]
[tex]\text{Total cubes}=x^2[/tex]
Total number of cubes = 225
[tex]x^2=225[/tex]
Taking square root on both sides.
[tex]x=\sqrt{225}[/tex]
[tex]x=15[/tex]
So, the number of cubes in a row is 15.
Therefore, the correct option is A.

Jaythen finds a shirt on sale for 10% off at a store. The original price was $20. Jaythen must also pay 8.5% sales tax. How much is the shirt before taxes? *
How much does Jaythen pay total for his shirt after taxes? *
Answer:
the shirt before taxes is $18. the shirt after taxes is 19.53
Step-by-step explanation:
you multiply 20x.10 and you'll get 2. so you subtract 2 from 20, that's $18.
to get taxes, you multpliply 18x.085 and you get $1.53.
you then add $1.53 to 18 and you get your total price of $19.53
Answer:
Before taxes, the shirt was $18. After taxes. the shirt is $19.53

Peter works as a delivery person for a bike shipping company. The graph shows a linear model for his
delivery times on different days.
(a) what is the equation of the line, first written in point-slope form and then written in slope- intercept form? show how you determined the equation.
(b) based on the linear model, predict how long it initially took peter to deliver his packages (y-intercept) approximately how much did his delivery time decrease per day (slope)? Complete sentences
Answer/Step-by-step explanation:
a. Using a point on the graph, (6, 12), and the slope of the line, we can first generate an equation in the point-slope form, given as [tex] y - b = m(x - a) [/tex], where,
m = slope, and (a, b) is a point on the line.
Using two points, (6, 12) and (3, 21), let's find slope, m.
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{21 - 12}{3 - 6} = \frac{9}{-3} = -3 [/tex]
Using a point (6, 12) and slope, m = -3, generate an equation in the point-slope form by substituting a = 6, b = 12, and m = -3 in [tex] y - b = m(x - a) [/tex].
✅Equation in point-slope form would be:
[tex] y - 12 = -3(x - 6) [/tex]
Rewrite this to make it be in the slope-intercept form, [tex] y = mx + b [/tex].
[tex] y - 12 = -3(x - 6) [/tex]
[tex] y - 12 = -3x + 18 [/tex]
Add 12 to both sides
[tex] y = -3x + 18 + 12 [/tex]
[tex] y = -3x + 30 [/tex]
✅The equation in slope-intercept form is [tex] y = -3x + 30 [/tex]
b. ✍️Based on the linear model, [tex] y = -3x + 30 [/tex], the 30 represents b = y-intercept.
✅Therefore, it took Peter 30 mins long initially to deliver his package.
✍️Based on the linear model, [tex] y = -3x + 30 [/tex], "-3" represents the slope.
✅Therefore, Peter's delivery time decreased 3 mins per day.

5x = 10 can someone help me
Answer:
X=2
Step-by-step explanation: To get a single
x
, divide
5
x
by
5
.
Whatever you do to one side of the equals sign, you must do to the other side. This means, to get the right answer, you must do
5
x
5
=
10
5
The
5
's on the left side of the equals sign cancel out so it would make
5x5=105
and then
x=105105
is equal to
2
so...
x=2
Answer: Hey user! x = 2.
Step-by-step explanation: Step 1: Divide both sides by 5.
5x /5 = 10 /5
x=2

I need help with this: 100 marked down 65%
Answer:
The item is now 35$.
Step-by-step explanation:
First, find 65% of 100, which is 65. Then subtract the discount, or the "mark down" from 100. This gets you $35, so the item is $35 after the mark down.

[tex]\begin{pmatrix}x=-1,\:&y=3\\ x=-3,\:&y=1\end{pmatrix}[/tex]
Step-by-step explanation:
Given the system of the equations
[tex]y=x^2\:+\:5x\:+\:7[/tex]
[tex]y\:=\:x\:+4[/tex]
steps to solve the system of the equations
[tex]\begin{bmatrix}y=x^2+5x+7\\ y=x+4\end{bmatrix}[/tex]
subtract the equations
[tex]y=x^2+5x+7[/tex]
[tex]-[/tex]
[tex]\underline{y=x+4}[/tex]
[tex]y-y=x^2+5x+7-\left(x+4\right)[/tex]
[tex]0=x^2+4x+3[/tex]
solving
[tex]0=x^2+4x+3[/tex]
[tex]\left(x+1\right)\left(x+3\right)=0[/tex]
[tex]x+1=0\quad \mathrm{or}\quad \:x+3=0[/tex]
[tex]x=-1,\:x=-3[/tex]
[tex]\mathrm{Plug\:the\:solutions\:}x=-1,\:x=-3\mathrm{\:into\:}y=x^2+5x+7[/tex]

[tex]y=\left(-1\right)^2-5\cdot \:1+7[/tex]
[tex]y=1-5+7[/tex]
[tex]y=3[/tex]
Now substitute [tex]x=-3[/tex] into [tex]y=x^2+5x+7[/tex]
[tex]y=x^2+5x+7[/tex]
[tex]y=\left(-3\right)^2+5\left(-3\right)+7[/tex]
