A total of 40 parents volunteered to bring a cake for the Holiday fair.Of the 40 volunteers that brought cake,10 of them brought two cakes. Out of all the cakes at the holiday Fair , 30% were chocolate. How many cakes were chocolate?
Answer:
15!
Step-by-step explanation:
so 40 people volentered to bring cakes, but 10 brought 2. So (30*1)+(10*2)=50 cakes. So, 30 percent of 50 cakes would be 15. To double check, times 50 by 100 and then 30 percent would become 30 (making super sure the actual answer is 15)
Solve the equation (4x – 24) + x = 14.
Distribute the į to the quantity to get:
Combine the like terms to get
Add 6 to both sides to get:
Answer:
(4x – 24) + x = 144x - 24 + x = 14(4x + x) - 24 = 145x - 24 + 24 = 14 + 245x = 385x/5 = 38/5x = 7.6The World Health Organization (WHO) suggests having 23 health-care workers for every 10,000 people.

AThe formula for the area of a trapezoid treats the distance between the parallel sides as the height. Doing this lists the height as 4m.
BYou can separate a trapezoid into a rectangle with a width of 3 and a height of 4, as well as a right triangle with a width of 2 and a height of 4.
CThis expression is the written out portion of separating the trapezoid into a triangle and rectangle.
(3 * 4) represents the rectangle and (1/2 * 2 * 4) represents the triangle.
DThe area as found by the accurate expression in part C is 16.

Shannon scored 36 point on 6 questions on her test. what is the unit rate for one question?
Answer:
6 poinnts per question
Step-by-step explanation:
Answer:
x = the number of points for each question
6 = number of questions
36 = total number of points
number of questions times the number of points will equal total points
6x = 36
divide both sides by 6
6x/6 = 36/6
x= 6

Answer:
The missing angle to this triangle is 55 degrees, x is 14.65, and the other missing length is 8.4.
Step-by-step explanation:
In a triangle, all of the angles sum up to 180 degrees. We are given it is a right triangle with another given angle of 35 degrees. 180 degrees - 90 degrees - 35 degress is 55 degrees. Now, we can use law of sines to find x. x / sin 90 degrees = 12 / sin 55 degrees. sin 90 degrees can be simplified to 1. x = 12 / sin 55 degrees. x = 14.65. By using the pythagorean theorem, we can find the last missing side, which is 8.4.

If a1=4 and an =2an-1 – 1 then find the value of a4.
The value of [tex]a_{4} = 37[/tex].
Here,
The value of [tex]a_{1} = 4[/tex]
And, [tex]a_{n} = 2 a_{n-1} -1[/tex]
We have to find value of [tex]a_{4}[/tex].
What is Sequence?
A sequence is a collection of elements that are arranged according to a specific pattern.
Now,
The value of [tex]a_{1} = 4[/tex]
And, [tex]a_{n} = 2 a_{n-1} -1[/tex]
Then to find value of [tex]a_{4}[/tex], we can find [tex]a_{2} , a_{3}[/tex] as;
[tex]a_{2} = -2(a_{1} ) - 1\\a_{2} = -2(4) - 1\\a_{2} = -9[/tex]
And,
[tex]a_{3} = -2(a_{2} ) - 1\\a_{3} = -2(9) - 1\\a_{3} = -19[/tex]
Hence, the value of [tex]a_{4}[/tex] is;
[tex]a_{4} = -2(a_{3} ) - 1\\a_{4} = -2(-19) - 1\\a_{4} = 37[/tex]
Therefore, The value of [tex]a_{4} = 37[/tex].

Determine the probability of rolling a number that is not even.
a. Which outcome or outcomes make up the event of rolling a number that is not even?
b. Calculate the probability of rolling a number that is not even.
Answer:
[tex]\frac{1}{2}[/tex] or 0.5 or 50%
Step-by-step explanation:
P(not even) = P(odd) = P(1) or P(3) or P(5) = P(1) + P(3) + P(5)
= [tex]\frac{1}{6}[/tex]+ [tex]\frac{1}{6}[/tex]+[tex]\frac{1}{6}[/tex] = [tex]\frac{3}{6}[/tex]= [tex]\frac{1}{2}[/tex]
Alternatively

The diameter of a bacteria species A is 1 micrometre long while bacteria B is 1 x 10^-3 the size of bacteria species A.
a) What is the diameter of bacteria species B in metres?
Answer:
1 × 10⁻⁹ mStep-by-step explanation:
A is 1 micrometer = 1 × 10⁻⁶ m
B is 1× 10⁻³ size of A:
1 × 10⁻⁶ * 1 × 10⁻³ = 1× 10⁻⁹ mSolve for m.
9m - (6m - 7) = 2 (m - 3)
Answer:
[tex]\boxed{\boxed{\tt m=-13}}[/tex]
Step-by-step explanation:
[tex]\tt 9m-\left(6m-7\right)=2\left(m-3\right)[/tex]
Expand, Apply the Distributive property:
[tex]\tt 9m-\left(6m-7\right)\leadsto \underline{3m+7}[/tex]
[tex]\tt 2\left(m-3\right)\leadsto \underline{2m-6}[/tex]

Subtract 7 from both sides:
[tex]\star \:\:\tt 3m+7-7=2m-6-7[/tex]
[tex]\star \:\: \tt 3m=2m-13[/tex]
Subtract 2m from both sides:
[tex]\star \:\: \tt 3m-2m=2m-13-2m[/tex]
[tex]\star \:\: \tt m=-13[/tex]
_____________________________Janice bought an antique clock originally priced at $967 but on sale for 5% off. After 1% sales tax, what was the total cost?
Answer:
927.84
Step-by-step explanation:
The total cost of the antique clock that Janice bought is $927.82 approximately.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
For this case, we have:
Original price of clock = $967Sale discount = 5% on original price1% sales tax on the discounted priceTotal cost = (discounted price of clock)'s price + sales tax of discounted price.
Let d = discounted price of the clock
Then, we have:
[tex]d = $967 - \text{5\% discount on 967} \\\\d = 967 - \dfrac{967}{100} \times 5 = \$918.65[/tex]
1% sales tax on 'd' will be: [tex]\dfrac{d}{100} \times 1 = \$9.1865 \approx \$9.19[/tex]
Thus, we get:
Total cost of the clock ≈ 918.65 + 9.19 = 927.82 (in dollars)
Thus, the total cost of the antique clock that Janice bought is $927.82 approximately.

what are sides 'a' and 'b' called in a right triangle
Answer:
The relation between the sides and angles of a right triangle is the basis for trigonometry.
Step-by-step explanation:
The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (sides a and b ).
Answer:
The legs
Step-by-step explanation:
In a right triangle, sides a and b are called "the legs." These are the sides that create the right angle. Side c is called the hypotenuse and it is the longest side of a right triangle. Side c is opposite of the right angle.

PLSS HELP IMMEDIATELY!!!! ILL MARK BRAINIEST IF U DONT LEAVE A LINK OR GUESS!!!! (and it’s not multiplying. i already tried that)
Answer:
120cm³
Step-by-step explanation:
The volume of a rectangular prism is the length multiplied by the width and height. You may not have multiplied correctly or multiplied all of the dimensions.
So, let's multiply our dimensions, 4cm × 6cm × 5 cm.
4 · 6 · 5 = 120
4 times 6 equals 24, then 24 times 5 is 120.
The volume of the box, then, is 120cm³. Remember to use the ³ (cubed) sign for volume.
Good luck :)
