Answer: which question
Step-by-step explanation:
Mary is building a rectangle enclosure for all her chickens. The length of the enclosure is 22.5m and the width is 13.2m. If she already has 30m of fencing, how much more does she need?
Answer:
41.4 meters
Step-by-step explanation:
22.5 + 13.2 = 35.7
35.7 × 2 = 71.4m (because of the other 2 sides of the rectangle)
71.4-30=41.4m
From a sample tray, 4 of the last 10 cake samples chosen were strawberry. Based on past data, of the next 20 samples taken, how many should you expect to be pieces of strawberry cake?
Answer: 8
Step-by-step explanation:
There are 8 pieces of strawberry cake should you expect for 20 samples.
What is mean by Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
From a sample tray, 4 of the last 10 cake samples chosen were strawberry.
Hence, Let pieces of strawberry cake should you expect for 20 samples is, = x
Thus, By definition of proportion, we get;
⇒ 4/10 = x/20
⇒ 4 × 20 / 10 = x
⇒ x = 8
Thus, There are 8 pieces of strawberry cake should you expect for 20 samples.

A 30-foot ladder is set against the side of a house so that it reaches up 24 feet. If Elizabeth grabs the ladder at its base and pulls it 3 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 21 ft.) Round to the nearest tenth of a foot.
Use the Pythagorean theorem to calculate the distance from the wall the ladder originally is:
x = sqrt(30^2 - 24^2)
x = sqrt(900-576)
x = sqrt(324)
x = 18
The ladder was originally 18 feet from the wall. Moving the ladder 3 feet further away makes the new distance 18 + 3 = 21 feet.
Now use the Pythagorean theorem again to find the new height of the ladder.
Height = sqrt(30^2 - 21^2)
Height = sqrt(900 - 441)
Height = sqrt(459)
Height = 21.42
Rounded to the nearest tenth = 21.4 feet.

machine produces 195 bolts in 20 minutes. At the same rate, how many minutes would it take to produce 312 bolts?
Answer:
32
Step-by-step explanation:
There are two ways of doing this.
Frist, divide the amount of bolts by time. This will get you the bolts produced in 1 minute.
195/20
=
9.75
Now we know that 9.75 bolts are produced every 1 minute.
Lets divide the 312 bolts by the bolts produced per minute. This will give us the amount of minutes it takes to produce the 312 bolts.
312/9.75
=
32.
This is our answer.
Another way of doing thisis to divide the 20 minutes by 195, this will give you how long it takes to produce a single bolt.
20/195
=
0.1025
Now, just multpliy it by 312, and you get how long it takes to produce 312 bolts.
0.1025*312
=
32
And again, you get the answer.
Hope this helps! ;)
Answer:
32 I guess
Step-by-step explanation:
What is the domain of y = x + 1?
Answer:
[0, infinity
Step-by-step explanation:
It's essential to type "sqrt(x)" or "√x," which are vastly different from the linear function y = x + 1.
The domain of the square root function is [0, infinity).
Adding 1 to this merely shifts the entire graph up 1 unit.
So the domain of y = √x + 1 is the same as before: [0, infinity

Drag each situation to show whether it can be modeled using a linear or an exponential function. If the situation cannot be modeled with either function type, drag it into the container labeled Neither.
Answer: the savings account one is linear, the enrollment of students is linear, the investment is exponential as well as the cars value, the speed of the truck is neither (not fully sure) and the temperature outside is linear
Step-by-step explanation: linear means in a straight line without curves meaning if the question mentions percentages it’s automatically not linear as percentages tend to curve. Exponential means it curves which has direct connections to percentages and getting multiplied by

The vertex angle of an isosceles triangle is three times the measure of either base angle. Find the area if the measure of the congruent sides are 14 in
Answer:
[tex]Area = 93.21in^2[/tex]
Step-by-step explanation:
Given
[tex]\theta \to[/tex] vertex angle
[tex]\alpha \to[/tex] base angle
[tex]\theta = 3\alpha[/tex]
[tex]l = 14in[/tex] -- congruent sides
Required
The area of the triangle
First, calculate the angles
[tex]\theta + \alpha + \alpha = 180^o[/tex] ----- angles in an isosceles triangle
Substitute [tex]\theta = 3\alpha[/tex]
[tex]3\alpha + \alpha + \alpha = 180^o[/tex]
[tex]5\alpha = 180^o[/tex]
Divide both sides by 5
[tex]\alpha = 36^o[/tex]
Recall that: [tex]\theta = 3\alpha[/tex]
[tex]\theta = 3 * 36^o[/tex]
[tex]\theta = 108^o[/tex]
The area is then calculated as:
[tex]Area = \frac{1}{2}l^2 \sin(\theta)[/tex]
[tex]Area = \frac{1}{2}*14^2 \sin(108^o)[/tex]
[tex]Area = \frac{1}{2}*196 *0.9511[/tex]
[tex]Area = 93.21in^2[/tex]

Using words and equations, explain what you learned about exponents in this lesson so that someone who was absent could read what you wrote and understand the lesson. Consider using an example like 2^4 • 3^4 =6^4
I WILL MARK BRAINIEST FOR WHOEVER ANSWERS THE FASTEST
Answer:
Multiplication rule of exponents says [tex](xy)^n = x^n * y^n[/tex] hence, 2^4 • 3^4 =6^4
Step-by-step explanation:
As per the rule of exponents,
[tex](xy)^n = x^n * y^n[/tex]
If we go by the above equation, we can deduce that x is 2 and y is 3
Thus, 2^4 *3^4 can be written as [tex](2*3)^4 = 6^4[/tex]
Hence, 2^4 • 3^4 =6^4
Juan necesita para su coche verde 3dl y 75 ml de aceites,y para su coche azul 13cl y 5ml.¿Cuantos hl necesita en total? ¿Tendrá suficiente con una lata de medio litro?
Answer:
1. Juan necesita 0,0051 hl en total.
2. Juan no tendrá suficiente con una lata de medio litro.
Step-by-step explanation:
1. Para calcular el volumen total en hl, primero debemos convertir todas las unidades a hl.
Para el coche verde:
[tex] V_{1} = 3 dl*\frac{1 hl}{1000 dl} = 0,003 hl [/tex]
[tex] V_{2} = 75 ml*\frac{1 hl}{100000 ml} = 0,00075 hl [/tex]
Para el coche azul:
[tex] V_{3} = 13 cl*\frac{1 hl}{10000 cl} = 0,0013 hl [/tex]
[tex] V_{4} = 5 ml*\frac{1 hl}{100000 dl} = 0,00005 hl [/tex]
Ahora, para encontrar el volumen total debemos sumar todos los volúmenes anteriores:
[tex] V_{T} = V_{1} + V_{2} + V_{3} + V_{4} = 0,003 hl + 0,00075 hl + 0,0013 hl + 0,00005 hl = 0,0051 hl [/tex]
Por lo tanto, Juan necesita 0,0051 hl en total.
2. Luego, para saber si tendrá suficiente con una lata de medio litro, debemos convertir el volumen total de hl a l:
[tex] V_{T} = 0,0051 hl*\frac{100 l}{1 hl} = 0,51 l [/tex]
Entonces, dado que el volumen total es 0,51 litros Juan no tendrá suficiente con una lata de medio litro porque necesita cubrir 0,01 litros más.

Which number is the discriminant of a quadratic equation that has no solution?
1) 0
2) 36
3) -4
4) 5
Answer:
-4
Step-by-step explanation:
If the discriminant is negative there can be no real number solution because the square root of a negative number does not exist (in real numbers).
