Susie has three hours to
make 5 cakes. How many
minutes will each cake
require to make?
Please show how you did it step by step
Answer:
Susie has 36 minutes to make each cake.
Step-by-step explanation:
There are 60 minutes in an hour. Three hours had 180 minutes.
Divide 180 minutes by 5 cakes.
180/ 5 = 36.
Therefore we have 36 minutes per cake.

0.7(3s+4)−1.1s=7.9 I need a answer
First, expand the bracket
2.1s + 2.8 - 1.1s = 7.9
Next, collect like terms
s + 2.8 = 7.9
Lastly subtract 2.8 from 7.9 to get your answer.
s = 5.1
(Hope this helps! ^^)
Answer:
[tex]\boxed {s = 5.1}[/tex]
Step-by-step explanation:
Solve for the value of [tex]s[/tex]:
[tex]0.7(3s + 4) - 1.1s = 7.9[/tex]
-Use Distributive Property:
[tex]0.7(3s + 4) - 1.1s = 7.9[/tex]
[tex]2.1s + 2.8 - 1.1s = 7.9[/tex]
-Combine like terms:
[tex]2.1s + 2.8 - 1.1s = 7.9[/tex]
[tex]s + 2.8 = 7.9[/tex]
-Subtract [tex]2.8[/tex] to both sides:
[tex]s + 2.8 - 2.8 = 7.9 - 2.8[/tex]
[tex]\boxed {s = 5.1}[/tex]
So, the value of [tex]x[/tex] is [tex]5.1[/tex].
Use the following information to find x. Write the value of the variable.

A $240 suit is marked down by 10% what the sale price
Sales price of suit is equals to $216 after applying 10% discount.
What is discount?
" Discount is deduction by some percent or amount in the original price of any product."
Formula used
Sales price = Marked price - discount amount
Discount = ( Marked price × discount %) /100
According to the question,
Marked price of the suit= $240
Discount % on the suit =10%
Substitute the value in the formula we get,
Discount = (240 × 10) / 100
= $24
Sales price = $240 - $24
= $216
Hence, Sales price of suit is equals to $216 after applying 10% discount.

I just need 8 and 9 pls help been stuck here forever
Answer:
8: C
9: D
10: C
11: D
Step-by-step explanation:
On number 8, the pattern is by starting from 3, and squaring it. Then you take that square and square it again. So 3 squared is 9, and then you square 9 which is 9 times 9 giving you 81. Then you square 81 giving you 6561.
9: Negative exponents work by flipping the number upside down, and then doing normal exponential work on the now denominator.
If the number is 5 to the power of -3, you are flipping 5 to 1/5 and then doing 5 to the power of 3 which is 5x5x5 giving you 125. Therefore the answer would be 1/125.
10 is the same thing as number 9 except backwards, so you flip 1/2^3 to 2^-3
11 is similar, except you have 3.471 times 1/10000
So you add 4 zeros in front of the 3.471 turning it into 0.0003471

Can you help me please (x-2)(x-3)=0
=====================================================
Explanation:
Use the zero product property. This is the idea where if A*B = 0, then either A = 0 or B = 0.
This works because 0 times any number is always 0.
In this case A = x-2 and B = x-3
So,
(x-2)(x-3) = 0
x-2 = 0 or x-3 = 0
x = 2 or x = 3
------------------
If we plugged x = 2 back into the original equation, we get
(x-2)(x-3) = 0
(2-2)(2-3) = 0
(0)(-1) = 0
0 = 0
Which confirms x = 2
Let's do the same for x = 3
(x-2)(x-3) = 0
(3-2)(3-3) = 0
(1)(0) = 0
0 = 0
So x = 3 is confirmed as well.

6(x2-10x )+438 Do (b/2)2 to find the c term. (-10/2)2 = 25
6(x2-10x+25)+438-150 Adding 25 inside the parenthesis is really like adding 6(25)=150 to that side of the equation. To keep the equation in balance, you have to subtract 150 from the other term. Simplify

what is the measure of angle MBT
Answer : The measure of angle MBT is 28°.
Step-by-step explanation :
As we see that the ∠NBM is equal to ∠MBT.
That means,
∠NBM = ∠MBT
Given:
∠NBM = (17x - 6)°
∠MBT = (5x + 18)°
According to question:
∠NBM = ∠MBT
(17x - 6)° = (5x + 18)°
17x - 5x = 18° + 6°
12x = 24°
x = 2°
So,
∠NBM = (17x - 6)° = [(17 × 2) - 6]° = 28°
∠MBT = (5x + 18)° = [(5 × 2) + 18]° = 28°
Hence, the measure of angle MBT is 28°.
Answer:
the answer is 28

Can anybody help me on this math question for number 3 and Find the measure of each interior angle of the regular polygon?
Answer:
the measure of each angle is 150.
Step-by-step explanation:
in order to find this you need to find the measure all the degrees which can be found with (n-2)x180
in this case this is (12-2) x 180
so you would get the total degrees in the inside is 1,800
then there are a total of 12 interior angles so divide 1,800 by 12 to get 150 for each interior angle (btw this is only possible since this is a regular polygon meaning that every one of the angles are the same )

Find the value of x in each case:
Answer:
x=19°
Step-by-step explanation:
Angles ∡DBE ≅ ∡ACD= 3x reason - angles with parallel arms
Angles ∡ADC and ∡ADB=95° are supplemental angles which means
∡ADC + ∡ADB=180° => ∡ADC = 180° - ∡ADB= 180°-95°= 85°
In the triangle we have ∡ADC + ∡ACD + ∡CAD = 180° =>
85 + 3x + 2x = 180 => 85 + 5x = 180 => 5x= 180-85 => 5x=95
x=95/5 => x=19°

12. Which line has an x-intercept of -1 and a
y-intercept of 1?
A. y = -x
B. x - y = 1
C. x - y = -1
D. x + y = 1
Answer:
#4
Step-by-step explanation:
1) The y intercept is 0.
2) Convert to slope-intercept form:
2x + 3y = 12
3y = -2x + 12
y = -2/3 x + 4
So the y-intercept is 4.
3) Write in point-slope form:
y + 4 = 2 (x - 1)
Now convert to slope-intercept form:
y + 4 = 2x - 2
y = 2x - 6
So the y-intercept is -6.
4) The y-intercept is 5.
So of the four lines, #4 has the largest y-intercept.
The line with an x-intercept of -1 and a y-intercept of 1 is C. x - y = -1
A linear equation is of the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept
Given the line x - y = -1, the x intercept is at y = 0, hence:
x - 0 = -1
x = -1
The y intercept is at x = 0, hence:
0 - y = -1
y = 1
The line with an x-intercept of -1 and a y-intercept of 1 is C. x - y = -1
