The community service club is raising money for a children's hospital. Earlier in the year, the club had raised $240 for the charity. The club then held a bake sale and after the sale they were able to donate a total of $750 to the charity. Write an equation and solve for the amount raised at the bake sale.
During a sprint, a basketball player is traveling at +3 m/s. Four seconds later, the player is traveling at –5 m/s. The average acceleration of the basketball player over the last 4 seconds is:
Answer:
the average acceleration of the basketball player over the last 4 seconds is 0.5 m/sec^2
Step-by-step explanation:
The computation of the average acceleration is shown below:
= Change in velocity ÷ change in time
= 5 - 3 ÷ 4
= 2 ÷ 4
= 0.5 m/sec ^2
Hence, the average acceleration of the basketball player over the last 4 seconds is 0.5 m/sec^2
which of the following equations is equivalent to log(y) = 4.876
Answer:
[tex]10^{4.876}=y[/tex]
Step-by-step explanation:
Logarithms are just another way of arranging an exponential equation! You know how you can rearrange the equation 2 + 3 = 5 as 5 - 3 = 2, or the equation 2 x 3 = 6 as 6 ÷ 3 = 2? With logarithms, you can do the same thing with an equation like 2³ = 8. As a logarithm, we would write this equation as log₂(8) = 3. Here, we call 2 the base, 8 the argument, and 3 the exponent.
Logarithms like the one in the problem with a base of 10 are just written as log, without the base written out. In the equation log(y) = 4.876, our base is 10, our argument is y, and our exponent is 4.876, so as an exponential equation, we would write it as
[tex]10^{4.876}=y[/tex]
Use triangles to find the sum of the interior angle measures of the polygon.
Answer:
1440°
Step-by-step explanation:
From the 8 sided diagram, 8 triangles can be obtained. 1 triangle adds up to 180° thus for the diagram ,sum of interior will be 180°×8=1440°
Sara picked 18 to 24 roses she divided flowers into groups so that the same number of tulips and roses were in each bouquet. What is the greatest number of bouquets she could have
Answer:
6 bouquet
Step-by-step explanation:
To obtain the greatest number of bouquet she could have ;
Obtain the greatest common factor of 18 and 24
Factors of 18 : 1 , 2, 3, 6, 9, 18
Factors of 24 : 1, 2, 3, 4, 6, 8, 12, 24
The greatest factor commo to both 18 and 24 is 6.
Hence, the greatest number of bouquet she could have is 6.
If side x has a length of 15 cm and side y has a length of 4 cm, then which value below could be the length of side z?
A.
20 cm
B.
21 cm
C.
17 cm
D.
10 cm
Answer:
Step-by-step explanation:
You should start with 10. The problem with 10 is that if you add 4 to it, the sum is less than 15, so no triangle will form.
A and B won't work either 4 + 15 is 19. A and B are both longer than 19 so no triangle will form.
The answer has to be C. 4 and 15 make 19. That's more than 17 so a triangle will be formed.

Which of the expressions have like terms? select all that apply
A. 14m + mn
B. 2y + 2x + 4
C. -3/4m + 8m + m
D. 4 - 3p
E. 5.75t + 7.75t - t
F. 8xy - 6xy
Answer:
C, E and F
Step-by-step explanation:
As,
C. - 3/4 m + 8m + m. [Like terms of m]
= 29/4 m + m
= 33/4 m
E. 5. 75t + 7.75 t - t. [Like terms of t]
= 13.5t - t
= 12 . 5t
F. 8xy - 6xy. [Like terms of xy]
= 2xy

here is a formula:
a=2b-c
what is the value of a if b=12 and c=-4
Answer:
a=28
Step-by-step explanation:
a = 2b - c
a = 2(12) - (-4)
a = 24 + 4
a = 28
by the formula
a=2b-c
if b =12
so, a= 2*12-(-4)
a= 24+4
a=28

−9x−6y=15
9x−10y=145
y=
x=
Answer:
Step-by-step explanation:
Adding the two equations together gives you
9x-10y-9x-6y=145+15
-16y=160
y=-10, using this value in 9x-10y=145 gives you
9x-10(-10)=145
9x+100=145
9x=45
x=5
So y=-10 and x=5
Quarters have a coating of copper mixed with nickel on the outside. If the diameter of a quarter is 24.3 mm, then what is the surface area of one side of the quarter that will get coated?
Answer: 463.96 mm² or 46.4 cm²
Step-by-step explanation:
Quarters are circular in shape so the surface area of one side will be the area of a circle.
Area of a circle = π * r²
Radius = Diameter / 2
= 24.3 / 2
= 12.15 mm
Area = 22/7 * 12.15²
= 463.96 mm²
you will explain how to go about solving for the unknown letters A B C D using your angle vocabulary /concepts. Organize your sentences in a way that clearly emphasis your understanding of this unit.
Angle vocabulary/ concepts :
Supplementary Angle
Transverse Angles
Complimentary Angle
Triangle Sum Theorem
Right Angle
Straight Angle
Vertical Angel
Congruent
Parallel Lines
Answer:
To find c° go with Triangle Sum Theorem .
To find d° go with Supplementary Angle with 58°.
To find a° go with Transverse Angles.
To find b° go with Transverse Angles .
Step-by-step explanation:
c° = 180- 58 - 48 = 74°
b° = 48°
d° = 180 - 58 = 122°
a° = 58°

Simplify. Your answer should contain only positive exponents.
Answer:
[tex]\frac{1}{4k^3}[/tex]
Step-by-step explanation:
It's already in a form that only ha positive exponents. Just to state it though you could rewrite it as [tex]k*(4k^{4})^{-1}[/tex] or [tex]k*4^{-1}*k^{-4}[/tex] The question asks for positive exponents though so yu don't need to do that.
You also need to know [tex]\frac{x^a}{x^b}=x^{a-b}[/tex] so in this case [tex]\frac{k}{k^4}=\frac{k^1}{k^4} =k^{1-4}=k^{-3}=\frac{1}{k^3}[/tex]
so [tex]\frac{k}{4k^4}=\frac{1}{4}*\frac{k}{k^4}=\frac{1}{4}*\frac{1}{k^3}=\frac{1}{4k^3}[/tex]
