In the diagram below, ZDAB and ZDAC are adjacent
angles.
Complete Question: In the diagram below, <DAB and <DAC are adjacent angles. If m<DAC = 25°, what is m<DAB in degrees? What is m<BAC in degrees?
Answer:
m<DAB = 80°
m<BAC = 105°
Step-by-step explanation:
Generate an equation that will help you find the value of x.
Since m<DAC = 25°, therefore, x - 20 = 25°
Use this equation to find x
x - 20 = 25
Add 20 to both sides of the equation
x - 20 + 20 = 25 + 20
x = 45
m<DAB = 2x - 10
Plug in the value of x
m<DAB = 2(45) - 10 = 90 - 10 = 80°
m<BAC = m<DAC + m<DAB
m<BAC = 25 + 80 = 105°
solve the equation for k-2/4 = 10 Help solve this question please.
Answer:
I think K = 10.5
Step-by-step explanation:
First you would do the division of 2/4 which equals 0.5. Now the equation is k-0.5 = 10. If you flip the equation around it is 10 + 0.5 = k. Now you would know that k = 10.5 to check it does 10.5 - 0.5 = 10? Yes.

A 10 ounce box of cheerios cost $2.80 ounce box of cheerios cost $5.20. which is cheaper by the ounce.
Answer: 20 ounces box of cheerios is cheaper.
Step-by-step explanation:
If 10 ounce box of cheerios cost $2.80 and 20 ounce cost $5.20 then to find which is cheaper, you need to find the unit price which is the cost of an ounce.
Divide the money by the amount of ounces.
2.80 / 10 = 0.28 which is 28 cents per ounce.
5.20/20 = 0.26 which is 26 cents per ounce.
So the 20 box of cheerios is cheaper because it is 2 cents less.

The International Business Club starts the school year with $250.50 in their account. They spend $35 each month on activities. The Future Agricultural Leaders Club starts with $300 and spends $45.25 each month. Which equation can be used to find m, the number of months it will take for both accounts to have the same amount of money? 250.5 + 35m = 300 + 45.25m 250.5 – 35m = 300 – 45.25m 250.5m – 35 = 300m – 45.25 250.5m + 35 = 300m + 45.25
Answer:
250.50 - 35m = 300 - 45.25m
Step-by-step explanation:
Whenever an equation asks for when it will take x (or m in this case) amount of things or time you should know that there will be 2 different equations that have to equal each other
The equation will be 250.50 - 35m = 300 - 45.25m
The 35m is being subtracted from 250.50 because they are losing money each time they spend. This also applies to 45.25m
Also 35m and 45.25m are variables because it says they spend that much money each month. They don't specify how many months, so we have to put a variable after it.
Answer:
b) 250.5 – 35m = 300 – 45.25m

Which statement describes function composition with respect to the commutative property?
O Given f(x) = x2 - 4 and g(x) = x-3, (fºg)(2) = -3 and (gºf)(2) = -3, so function composition is commutative.
O Given f(x) = 2x-5 and g(x) = 0.5x - 2.5, (fºg)(x) = x and (gof)(x) = x, so function composition is commutative
Given f(x) = x? and g(x)=xx. (fºg)(0) = 0 and (gºf)(0) = 0, so function composition is not commutative.
O Given f(x) = 4x and g(x) = x? (fog)(x) = 4x2 and (gºf)(x) = 16x?, so function composition is not commutative
Answer:
Given f(x) = 4x and g(x) = x², (f ∘ g)(x) = 4x² and (g ∘ f)(x) = 16x², so function composition is not commutative.
Step-by-step explanation:
Option D is correct, given f(x) = 4x and g(x) = x², (fog)(x) = 4x² and (gof)(x) = 16x², so function composition is not commutative.
What is a function?A relation is a function if it has only One y-value for each x-value.
Function composition is not commutative in general, meaning that (fog)(x) is not equal to (gof)(x) for all functions f and g.
Let f(x) = 4x and g(x) = x², for which function composition is not commutative.
If we compose f and g, we get:
(fog)(x) = f(g(x)) = f(x²) = 4x²
If we compose g and f, we get:
(gof)(x) = g(f(x)) = g(4x) = (4x)² = 16x²
Since (fog)(x) is not equal to (gof)(x) for all x, we can conclude that function composition is not commutative in this case.
Hence, f(x) = 4x and g(x) = x², (fog)(x) = 4x² and (gof)(x) = 16x², so function composition is not commutative, option D is correct.

Many cereals are made with high moisture content so that the cereal can be formed into various shapes before it is dried. A cereal product containing 57% by mass is produced at the rate of 1000. kg/h. How much water must be evaporated per hour if the final product contains only 21% water
Answer:
278.482 kilograms of water must be evaporated each hour.
Step-by-step explanation:
Initial mass of cereal is equal to the product of cereal mass-to-mass ratio and total mass flow:
[tex]\dot m_{in,c} = r_{in,c}\cdot \dot m_{in}[/tex]
Where:
[tex]\dot m_{in,c}[/tex] - Inlet cereal mass flow, measured in kilograms per hour.
[tex]r_{in,c}[/tex] - Inlet cereal mass ration, dimensionless.
[tex]\dot m_{in}[/tex] - Cereal product mass flow, measured in kilograms per hour.
If [tex]r_{in,c} = 0.57[/tex] and [tex]\dot m_{in} = 1000\,\frac{kg}{h}[/tex], then:
[tex]\dot m_{in,c} = (0.57)\cdot \left(1000\,\frac{kg}{h} \right)[/tex]
[tex]\dot m_{in,c} = 570\,\frac{kg}{h}[/tex]
The initial mass flow of water is:
[tex]\dot m_{in,w} = \dot m_{in} - \dot m_{in, c}[/tex]
[tex]\dot m_{in,w} = 1000\,\frac{kg}{h}-570\,\frac{kg}{h}[/tex]
[tex]\dot m_{in,w} = 430\,\frac{kg}{h}[/tex]
Given that final total mass flow contains only 21 % water, the final water mass flow, measured in kilograms per hour, is:
[tex]\dot m_{out} = \frac{\dot m_{out, c}}{r_{out, c}}[/tex]
([tex]\dot m _{out, c} = 570\,\frac{kg}{h}[/tex], [tex]r_{out} = 0.79[/tex])
[tex]\dot m_{out} = \frac{570\,\frac{kg}{h} }{0.79}[/tex]
[tex]\dot m_{out} =721.518\,\frac{kg}{h}[/tex]
[tex]\dot m_{out,w} = \dot m_{out} - \dot m_{out, c}[/tex]
[tex]\dot m_{out,w} = 721.518\,\frac{kg}{h}-570\,\frac{kg}{h}[/tex]
[tex]\dot m_{out,w} = 151.518\,\frac{kg}{h}[/tex]
Finally, the amount of water that must be evaporated per hour is:
[tex]\dot m_{evap} = \dot m_{in,w}-\dot m_{out,w}[/tex]
[tex]\dot m_{evap} = 430\,\frac{kg}{h} - 151.518\,\frac{kg}{h}[/tex]
[tex]\dot m_{evap} = 278.482\,\frac{kg}{h}[/tex]
278.482 kilograms of water must be evaporated each hour.

Last month Bill spent $6,000. How much did bill spend on taxes last month? (1) The total amount Bill spent on taxes was 70% of the amount he spent on groceries. (2) 40% of the total amount Bill spent last month was spent on taxes and groceries.
Answer:
Bill spent $988 on taxes.
Step-by-step explanation:
First, you have to find the total amount that Bill spent last month on taxes and groceries as the statement says that he spent 40% of the total amount on that:
$6,000*0.4=$2,400
Then, the statement indicates that the total amount Bill spent on taxes was 70% of the amount he spent on groceries.
Let's consider that:
x=taxes
y=groceries
With the information we can write the following:
x+y=2,400 (1)
x=0.7y (2)
You can replace 2 in 1:
0.7y+y=2,400
1.7y=2,400
y=2,400/1.7
y=1,412
Then, you can replace the value of y in 2:
x=0.7(1,412)
x=$988
According to this, Bill spent $988 on taxes.

Answer:
124
Step-by-step explanation:
we are given 146 right away.
That little square means a 90 degree angle
146 + 90 = 236
360 - 236 = 124
(360 degrees is the sum of a complete circle.)
The measure of the arc (ABC) is 270 degree.
What is an angle?In plane geometry, an angle is a shape made up of two rays or lines with the same terminal.
Angle can be used to measure any angular rotational motion since it cannot be measured in terms of length parameters like metres or inches. Instead, it is measured as an angle in terms of degrees or radians.
As we know that the angle of complete rotation is 360°.
So, ∠ADC + ∠ABC = 360
We know ∠ADC = 90°
Then, ∠ABC = 360° - 90°
∠ABC = 270°
