Answer: The best estimate for the amount of money she saves to buy clothes = $ 562.5
Step-by-step explanation:
Given: Breanna saves 75% of her earnings to buy new school clothes.
Earnings for Breanna = $ 750
The amount of money she saves to buy clothes = 75% of 750
= 0.75 x 750 [75%= 0.75]
= $ 562.5
Hence, the best estimate for the amount of money she saves to buy clothes = $ 562.5

What is the solution to the system of equations below?
y- x-3 and x = -10
0 (-10,-7)
0 (-10,-1)
0 (-7, -10)
0 (-1,-10)
Answer:
(-10,-7)
Step-by-step explanation:
the given equations: y=-3 and x=-10
we can substitute the x in the first equation as -10.
y=(2/5×-10)-3
simplify
y=(2/1*-2)-3
y=-4-3
y=-7
the y value is -7
we actually have the x value given as -10 (in the system)
So the answer is (-10,-7)

Joey is building a doghouse. He measures the lengths of two sides and the hypotenuse to make sure the boards create a right triangle.
Which of the measurements below could be used to create the right triangle?
5 in, 7 in, 12 in
8 in, 12 in 14 in
5 in, 9 in, 11 in
6 in, 8 in, 10 in
pleasee help mee
Answer: 6in, 8in, 10in
6 squared + 8 squared equals to the radical of 100, which equals to 10 because 10 squared is.. 100
The measurements that can be used to build a right-angled triangle are
[tex]6 in, 8 in, 10 in[/tex]
The measurements that can be used to build a right-angled triangle must form a Pythagorean triple. A Pythagorean triple is a set of three numbers [tex]\{x,y,z\}[/tex] that satisfy the Pythagorean relationship
[tex]x^2+y^2=z^2[/tex]
The measurements [tex]\{5 in, 7 in, 12 in\}[/tex] do not form a triple since
[tex]5^2+7^2=74\ne12^2[/tex]
The measurements [tex]\{8 in, 12 in, 14 in\}[/tex] do not form a triple since
[tex]8^2+12^2=208\ne14^2[/tex]
The measurements [tex]\{5 in, 9 in, 11 in\}[/tex] do not form a triple since
[tex]5^2+9^2=106\ne11^2[/tex]
The measurements [tex]\{6 in, 8 in, 10 in\}[/tex] form a triple since
[tex]6^2+8^2=100=10^2[/tex]
So, the last set of measurements [tex]6 in, 8 in, 10 in[/tex] can be used to build a right-angled triangle

how to calculate the volume of a cylinder if the height is 9.25 cm and the base is 6.5 cm
Answer:
306.94 cm
Step-by-step explanation:
The formula for volume of a cylinder is pi×r^2×h. Im assuming that you mean that the base is 6.5 cm in diameter so in this case you would plug in the values and do pi×3.25^2×9.25 and get 306.94 cm

7. A cone has a volume of 942 cubic inches
and a height of 9 inches. What is the radius of
the cone?
Answer:
Step-by-step explanation:
V of a cone V=3.14* r^2*h/3
942=3.14*r^2*9/3
r^2=942/(3.14*3)=100
r=sqrt100=10
The radius of the cone when the volume of 942 cubic inches and a height of 9 inches should be 10.
Calculation of the radius of the cone;
Since there is a volume of 942 cubic inches and a height of 9 inches
We know that
Volume of a cone V=[tex]3.14* r^2*h/3[/tex]
So,
[tex]942=3.14*r^2*9/3\\\\r^2=942/(3.14*3)=100[/tex]
r =[tex]\sqrt 100[/tex]
=10
hence, The radius of the cone when the volume of 942 cubic inches and a height of 9 inches should be 10.

The prism shown has a volume of 35 cm'.
Work out h, the height of the triangular cross section.
h
7 cm
4 cm
The height of the triangular cross section of the prism will be [tex]2.5 \ cm[/tex] .
What is prism ?Prism is a polyhedron comprising an [tex]n-[/tex]sided polygon base, a second base which is a translated copy of the first, and [tex]n[/tex] other faces, necessarily all parallelograms, joining corresponding sides of the two bases. All cross-sections parallel to the bases are translations of the bases.
And,
Volume of prism [tex]= Base\ Area\ *\ Length[/tex]
We have,
Volume of prism [tex]=35 cm^3[/tex]
Length of prism [tex]=7cm[/tex]
Height of prism [tex]=h\ cm[/tex]
We also have,
Base of triangle [tex]=4\ cm[/tex]
One of the side of triangle [tex]=5\ cm[/tex]
As we have Triangular prism so Base area of prism will be the area of triangle.
so,
Area of triangle [tex]=\frac{1}{2}*base*Height[/tex]
[tex]=\frac{1}{2} * 4*h[/tex]
Area of triangle [tex]=2h[/tex]
Now,
Volume of prism [tex]= Base\ Area\ *\ Length[/tex]
[tex]35=2h*7[/tex]
[tex]h=\frac{5}{2}[/tex]
[tex]h=2.5 \ cm[/tex]
So, the height of prism is [tex]2.5\ cm[/tex] .
Hence, we can say that the height of the triangular cross section of the prism will be [tex]2.5 \ cm[/tex] .

A small aircraft flies a 2160-mi round trip in a 45 mi/h wind. Find the average rate of speed for the trip if the aircraft can fly 225 mi/h with no wind.
9514 1404 393
Answer:
216 mi/h
Step-by-step explanation:
The time for the trip with the wind is ...
(1080 mi)/(225 +45 mi/h) = 4 h
The time for the trip against the wind is ...
(1080 mi)/(225 -45 mi/h) = 6 h
The average speed for the entire round trip is ...
(2160 mi)/(4 +6 h) = 216 mi/h

Step-by-step explanation:
Area of a Rectangle
The image shows a rectangular vegetable garden with different crops.
The rectangle has a length of L=2x+9 yards and a width of W=6x-3 yards.
The area of a rectangle is:
A = WL
[tex]A=(2x+9)(6x-3)[/tex]
Operating:
[tex]A=2x(6x)-2x(3)+9(6x)-9(3)[/tex]

[tex]\boxed{A=12x^2+48x-27}[/tex]
how do you work out this equation?
solve simultaneous equations by substitution
x + y =3
5x + y = 15
Step-by-step explanation:
x + y = 3. => y = 3 - x
5x + y = 5x + (3 - x) = 15.
=> 4x + 3 = 15
=> 4x = 12, x = 3.
Therefore y = 3 - (3) = 0.
The solutions are x = 3 and y = 0.
Answer:
Step-by-step explanation:
x+y=3
5x+y = 15
I method:
y = 3 - x. substitute this in 2nd equation
5x + (3-x) = 15
5x + 3 - x = 15
4x = 12
x=3
y=0
II method:
subtracting 2nd equation and 1st equation we get
4x +0y = 12
x = 3
y = 0
