Answer:
a + b = 100
a - b = 6
2a = 106
2a/2 = 106/2
a = 53
53 + b = 100
53 + b - 53 = 100 - 53
b = 47
Which line is parallel to the line y=x+7?
1) x+y=-2
2)x=1
3) x-y=5
4)y=1
Answer:
3
Step-by-step explanation:
to find the parallel of this line we need to find function with same slope
1) x+y=-2 ⇒ y=-x-2
2)x=1
3) x-y=5 ⇒ y=x-5
4)y=1
so third

Ja’quan was told to go inside one afternoon while he was at summer camp. He heard thunder and saw flashes of lightning. Suddenly, small balls and chunks of ice were falling on the field. Ja’quan checked the thermometer, because he never saw ice fall in South Florida, and noticed that it was 77°F (or 25°C). How was ice able to fall even though the temperature was much warmer than freezing? a) Ja’quan read the thermometer wrong b) He must have observed hail falling from thunder clouds c) It was cold enough to allow solid precipitation to fall d) Children were most likely throwing ice Reasoning (explain your answer using science facts) _________________________________________ _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Answer:
b
Step-by-step explanation:
hail can occur at temperatures not too cold and not too hot. since he checked his thermometer and it was warm, it is certainly possible that he saw hail
A card is drawn at random from a well-shuffled deck of 52 cards. what is the probability of drawing a face card or a spade?
Answer:
2/5 or 2:5
Step-by-step explanation:
Face Card:
The face cards in a deck are the Jack, Queen, and King. There are 4 of each card (1 in each suit), for a total of 12 face cards.
Spade:
1/4 of all the cards in a deck are spades, so 52/4= 13 spades.
When added, the numerator of the probability is 25, however, because the Jack, Queen, and King of Spades are duplicated, we have to subtract 3.
25-3=22
22/55
when simplified: 2/5

Mel is 7cm less then her grandma's height. Her brother is 11cm taller then his grandma. Together height total 502 cm. What are their heights?
Answer:
Mel's height is 159cm, her brother's height is 177cm and their grandma's height is 166cm.
Step-by-step explanation:
Let the grandma's height be g cm.
Mel's height= (g -7) cm
Brother's height= (g +11) cm
Total height
= Mel's height +brother's height +grandma's height
= g -7 +g +11 +g
= (3g +4) cm
Given that their total heights is 502 cm,
(3g +4) cm= 502 cm
3g +4= 502
3g= 502 -4 (-4 on both sides)
3g= 498
g= 166 (÷3 on both sides)
To find their heights, substitute g= 166 back into the expressions.
Grandma's height= 166cm
Mel's height
= 166 -7
= 159cm
Brother's height
= 166 +11
= 177cm
Find the surface area of this rectangular prism .
thanks!!!!!!!
Answer
Step-by-step explanation:
Answer:
solution given;
length [l]=9cm
breadth [b]=7cm
height[h]=3cm
we have
the surface area of this rectangular prism =2[lb×bh×lh]=2[9×7+7×3+9×3]=222cm²
is your answer
The length of a rectangle is 7 cm longer than its width.
The area of the rectangle is 120 cm².
What is the width of the rectangle?
Enter your answer in the box.
Answer:
length = 15 width = 8
Area 15x8 = 120
Step-by-step explanation:
L = length
W= width
L = W + 7 (width plus7)
Area = W x L
Area =W (W+7)
Do the distribution:
120 = W ² + 7W
Subtract 120 on both sides
W + 7W -120 = 0
Factor it
(W + 15)(W - 8) = 0
W = -15 or W = 8
8 is used for W
L = W + 7
L = 8+7=15
Length = 15
Width =8.

Find the volume of the triangular prism to the right
Answer:
V = 567 ft³
Step-by-step explanation:
V = Bh
[note: a capital 'B' represents the area of the base]
The right triangle is the triangular prism's base.
Because the triangle's height (9 ft) and it's base are the same value (9 ft), we can solve to find the area.
We can identify the base easily because the base and the top of the prism are exactly the same shapeArea of triangular base:
A = [tex]\frac{bh}{2}[/tex]
A = [tex]\frac{1}{2}[/tex] (9 ⋅ 9)
A = [tex]\frac{1}{2}[/tex] (81)
A = 40.5
We have 'B' for the triangular prism's formula, so next we need 'h'. 14 ft is provided as the prism's height, so we just need to multiply 40.5 and 14 for our answer.
Volume of triangular prism:
V = Bh
V = (40.5)(14)
V = 567 ft³

Convert the angle 17pi/12 radians to degrees.
Answer: 255°
Step-by-step explanation:
To convert an angle in radians to degree, we've to multiply it by 180/π. In this case, converting the angle 17pi/12 radians to degrees will be:
= 17π/12 × 180/π
= 17 × 15°
= 255°
The answer is 255°.
Boubacar went to the store to buy some walnuts. The price per pound of the walnuts
is $6.50 per pound and he has a coupon for $3.75 off the final amount. With the
coupon, how much would Boubacar have to pay to buy 4 pounds of walnuts? Also,
write an expression for the cost to buy p pounds of walnuts, assuming at least one pound is purchased.
Answer:
Step-by-step explanation:
Price per pound of the walnuts = $ 6.50
Price of 4 pounds of the walnuts = 4 *6.50 = $ 26
Amount needs to be paid = Price of 4 pounds of walnut - coupon amount
= 26 - 3.75
= $ 22.25
Expression:
Cost to buy p pounds of walnuts = p * 6.50 = 6.5p
Cost to buy p pounds of walnuts, assuming at least one pound is purchased = 6.50 + 6.5p
I’m not smart so help me please get it right
Answer:
Surface area = 148cm^2
Volume = 120cm^2
Step-by-step explanation:
You are smart don't say you're not. :)
Answer:
Surface Area is 148 cm^2
Your Volume will be 120 cm ^3
Step-by-step explanation:
Surface Area you get by getting the area of each of the 2 dimensional shapes, the formula to get the surface area for a rectangualr prism is 2(wl+hl+hw), so you would plug in 2((5(6))+((4(6))+(4(5)) which will give you 2((30)+(24)+(20)) which will then give you 2(74) and the final answer will be 148 cm^2
The formula for Surface Area is w(l)(h) so in this case it will be 5(6)(4) which will be 30(4)= 120 cm^3
Hope this helps
The perimeter of a rectangle is 13 cm and its width is 2 ¾ cm. Find its length in cm.
Answer:
length = 3 3/4
Step-by-step explanation:
13 = 2(2 3/4) + 2l
13 = 2(11/4) + 2l
13 = 22/4 + 2l
52/4 - 22/4 = 2l
30/4 = 2l
30/4 ÷ 2 = l
30/4 x 1/2 = l
30/8 = l
length = 15/4 or 3 3/4

Ryan conducted a 6-day study observing the effects of an organic plant food on the growth of his sprouting bean plant. He tracked these two pieces of information: the amount of plant food remaining in the container after each day's feeding the height of the plant over time
Answer:
[tex]Domain : 0\le x \le 6[/tex]
[tex]Range: 0 \le y \le 72[/tex]
Step-by-step explanation:
Given
See attachment for complete question
Required
Determine the domain and the range
From the complete question, we understand that the study was carried out for 6 days. This represents the domain;
So, we have:
[tex]Domain : 0\le x \le 6[/tex] i.e. from day 0 to day 6
Also, he experimented with 72ml, and he used an equal amount each day before he used up all the 72mL. This represents the range
So, the range is:
[tex]Range: 0 \le y \le 72[/tex] i.e. from 72mL to 0mL
